Colleagues,<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The AEC (UK) CAD Standards Initiative was formed in 2000 to
improve the process of design information production, management and exchange.
Initially the initiative addressed CAD layering conventions as the primary
concern for users of design data. As design needs and technology has developed,
the initiative has expanded to cover other aspects of design data production
and information exchange.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The committee was re-formed in 2009, including new members
from companies and consultancies highly experienced in BIM software and
implementation, to address the growing need within the UK AEC industry for a
unified, practical & pragmatic BIM standard in a design environment.<o:p></o:p></div>
<div class="MsoNormal">
The AEC (UK) BIM Standard was released in November 2009, and
this document forms part of that body of work, as a Revit-specific standard
which conforms with the platform-generic BIM standard. <o:p></o:p></div>

<div class="MsoNormal">
<i><b>Copyright Notice:</b><o:p></o:p></i></div>
<div class="MsoNormal">
<i>It is important to note that this standard will only become
truly useful if as many companies adopt it as possible. To that extent, it may
be freely distributed and used in any format necessary.</i><o:p></o:p></div>

<div align="center" class="MsoNormal" style="text-align: center;">
<br /></div>
<div class="MsoNormal">
My current interest in the notion of BIM Standards was
engendered during my work overseas, but I also learned that there are practical
limits to what can be achieved, depending on the market in which one's design
practice operates, along with many other factors.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Internationally, there is a wave of interest in
standardization, prompted by the 2016 UK Level 2 BIM Mandate. There is also an
overlay of academic interest in BIM, which can distort its practical
implementation.<o:p></o:p></div>

In addition, centrally funded government departments will be required to provide “clear and complete” Employer Information Requirements with all contracts. The mandate supports the UK’s 2025 Construction Strategy, which has four main goals: a 33% reduction in the initial cost of construction; a 50% reduction in the overall time; a 50% reduction in greenhouse gas emissions; and a 50% reduction in the trade gap between total exports and total imports for construction products and materials.</span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);"><br></span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);">In the much broader USA market, where the term ‘BIM’ was coined, several government agencies and private owners have driven development forward, and builders have recently surpassed designers and architects in the rate of BIM adoption, achieving a 70% adoption rate in 2012.</span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);"><br></span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);">A 2014 McGraw Hill report, The Business Value of BIM for Construction Major Global Markets, reports that “BIM usage is accelerating powerfully, driven by major private and government owners who want to institutionalize its benefits of faster, more certain projects delivery, and more reliable quality and cost.” It is further reported that “three-quarters of all contractors surveyed report a positive ROI on their investment in BIM.”</span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);"><br></span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);">BIM diffusion in Qatar, as defined by Dr. Bilal Succar on his BIM ThinkSpace blog (www.bimthinkspace.com) seems to be a blend of “Top-Down” pressure by clients and owners coupled with “Middle-Out” encouragement by global and multi-national designers and constructors.

I have a confession.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Before I came to practice BIM Management in Qatar, I had
never authored a BIM Execution Plan. I am really “old school” – I began doing
3D architectural modeling before it was called BIM. Among a fraternity of soon
to be geriatric colleagues (you know who you are) we were drawn to the
technology in search of a better way to create the instruments of service known
as drawings. A coordinated set of drawings without errors and inconsistencies
that always crept in to the multiple file methodology of CAD. Sure it was cool
that the process also yielded three-dimensional images, but 2D quality
improvement was the primary driver.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Flash forward 25-30 years. The stakes involved in BIM
delivery are much higher. Primarily because of improvements in computing
technology (processing power, speed, memory) we have loaded up BIM with many
more facets of building design technology. Visualization and analysis were once
separate processes – now they are integrated. Facility data management was a
manual process; now that too is expected to be delivered by BIM.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
In 2003, the United States General Services Administration
(GSA), through its Public Buildings Service (PBS) established its National
3D-4D-BIM Program. Agencies of the U.S. military (NAVFAC, USACE, USCG) were
among the first official bodies to recognize and institutionalize BIM for
design, construction and facility operations. The Associated General
Contractors of America (AGC) published its first Guide to Building Information
Modeling in 2006.<o:p></o:p></div>

The American Institute of Architects’ <a href="http://info.aia.org/siteobjects/files/ipd_guide_2007.pdf">Integrated
Project Delivery Guide</a>, which sets forth the principles of collaboration
which have become synonymous with BIM Nirvana – the simultaneous involvement of
all project stakeholders in the planning, design and execution of buildings and
other built assets – was published in 2007. The AIA’s <a href="http://www.aia.org/contractdocs/referencematerial/aiab099128">BIM

BIM project execution planning began in 2007 with the <a href="http://bim.psu.edu/">Penn State CIC</a> research program. BIM then was
typically just architectural modeling. “Information Exchange” was mostly
theoretical. It was difficult to convince structural engineers of the benefits,
and MEP BIM was virtually non-existent. In 2011, the Penn State CIC began the
development of the <a href="http://bim.psu.edu/">Owner's Guide to Building
Information Modeling</a>. The group determined there was a need to develop “a
guide for facility owners and operators that includes a procedure to develop a
strategy for integrating BIM throughout their organization.”</div>
<br />
<o:p></o:p>
<div class="MsoNormal">
In May 2011 the <a href="https://www.gov.uk/government/collections/government-construction">UK’s
Government Construction Strategy</a> was published, announcing the intention to
require collaborative 3D BIM (with all project and asset information,
documentation and data being electronic) on its projects by 2016. The “Level 2
Mandate” resulted in the creation of <a href="http://www.bimtaskgroup.org/pas-1192-22013/">PAS 1192</a> by the British
Standards Institute, which many consider to be the “Holy Grail” of BIM
implementation strategies. The UK’s <a href="http://www.cpic.org.uk/">Construction
Project Information Committee</a> (CPIc) is a consortium of construction industry
organizations. CPIc provides <a href="http://www.cpic.org.uk/cpix/">templates</a>
which support the PAS 1192 BIM strategy, and is the author of the new Uniclass2
classification system.<o:p></o:p></div>

precede the development of any BIM planning process. The <i>plain language questions</i> that must be asked and answered may
overlook the possibility that, especially in the MENA region, an employer (client,
owner) may just respond to some of those questions (i.e. “How will BIM be
managed and exploited in this project?) with an “I don’t know.” This should not
be a barrier to BIM delivery. Designers especially must be proactive and become
advocates for BIM development if progress is to be made.</div>
<br />
<o:p></o:p>
<div class="MsoNormal">
In the U.S. there is not a government mandate for BIM. The <a href="http://www.buildingsmart.org/">buildingSMARTalliance</a>, a council of
the National Institute of Building Sciences, employs a consensus approach to
the development of its National BIM Standard (NBIMS-US). BIM development in the
U.S. is driven by designers, builders and owners who believe in its benefits
and its ROI. Indeed, <a href="http://tangent.autodesk.com/i/545766-measuring-the-value-of-bim-achieving-strategic-roi/">a
study by Autodesk strategist Erin Rae Hoffer</a> indicates that the most
heavily invested firms have stopped measuring ROI because they simply
“believe”.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The uses for BIM span across three main categories – Design,
Construction, and Operations. 22 BIM uses were identified in the original Penn
State Guide. On his BIM Excellence website Dr. Bilal Succar has identified <a href="http://bimexcellence.com/model-uses/">125 model uses</a> (so far).<o:p></o:p></div>

<div class="MsoNormal">
As the well-known MacLeamy Curve illustrates, BIM shifts
design and construction project decision-making to an earlier project phase,
when the cost of changes is less, and the ability to impact design outcome is
greater. It is generally agreed that the major beneficiary of BIM is the owner,
with lower construction costs, fewer construction RFIs, and a more efficient
building or facility.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
So what are the immediate benefits for designers?</div>
<ul style="text-align: left;">
<li><span style="text-indent: -0.25in;">Reduction in waste and risk</span></li>
<li><span style="text-indent: -0.25in;">Improved design quality</span></li>
<li><span style="text-indent: -0.25in;">Reduction in errors</span></li>
<li><span style="text-indent: -0.25in;">Increased client, design, and construction team
understanding and communication</span></li>
<li><span style="text-indent: -0.25in;">Improved project delivery through efficient use
of resources, improved safety, and accurate timelines</span></li>
<li><span style="text-indent: -0.25in;">Accelerated regulatory approval and permitting</span></li>
</ul>
<div class="MsoNormal">
There is a vision of the future for building design and
construction professionals in which BIM is no longer considered to be an
alternative. It will be mainstream. BIM is the natural outcome of technology
applied to the process of creating buildings. The previous methods of design
delivery will eventually be seen as archaic, outmoded, and no longer relevant.<br />

<b>Project Delivery Methods</b><br />
<br />
True Integrated Project Delivery requires early involvement of the Constructor. <i>Multi-Party Agreements</i>, in the contractual forms of a Project Alliance, Single Purpose Entity, and Relational Contracts, define the process, decision-making procedure, sequencing of tasks, compensation, risk management, etcetera to be followed.<br />
<br />
In a multi-party agreement (MPA), the primary project participants execute a single contract specifying their respective roles, rights, obligations, and liabilities. In effect, the multi-party agreement creates a temporary virtual, and in some instances formal, organization to realize a specific project. Despite the custom nature of multi-party agreements, three general forms have emerged: Project Alliances; Relational Contracts; and Single Purpose Entities.<br />
<br />
In a <b>Project Alliance</b>, the owner guarantees the direct costs of non-owner parties, but payment of profit, overhead and bonuses depend on project outcome. Significant decisions are made by facilitated consensus and the parties waive liability, except in the case of willful default.<br />
<br />
A <b>Single Purpose Entity</b> (SPE) is a temporary, but formal, legal structure created to realize a specific project. In an integrated SPE, key participants have an equity interest based on their individual skill, creativity, experience, services, access to capital or financial contribution. Equity owners are paid for the services they provide, with additional compensation tied to overall project success.<br />
<br />
In <b>Relational Contracts</b>, the parties agree to limit their liability to each other, but it is not completely waived. Compensation structures have project-based incentives. Decisions are developed on a team basis, with the owner retaining final decision rights in the absence of team consensus.<br />
<br />
In some instances, participants may be required to use a delivery model that does not allow a constructor to be involved early in conceptualization (i.e. Design-Bid-Build). Other models, however, rely on earlier constructor involvement and would be more amenable to utilizing IPD methods (i.e. Construction Manager at Risk and Design-Build). Each of these traditional delivery methods present unique challenges to integration.<br />

<div>
Multi-Prime is commonly utilized within a Design-Bid-Build process. In this form of project delivery, the owner contracts directly with multiple contractors or trades. The owner acts as the general contractor on its own project. Multi-Prime project delivery requires that the owner provide substantial management services, and accordingly must have extensive experience and internal resources to perform the tasks which are typically managed by a general contractor or construction manager. When Multi-Prime is used for Design-Bid-Build, it offers few opportunities for IPD.</div>

In CM at Risk the construction manager is hired early in the design process to deliver an early cost commitment and to manage issues of schedule, cost, construction and building technology. Design remains the responsibility of an architect, who is independently contracted with the owner. A fully integrated CMc project might see the architect and constructor working with the owner to establish project goals, utilize BIM, and adopt other principles of integration and implementation techniques. Because work performed by trade contractors is typically bid, CMc satisfies the bidding requirements of most public procurement codes.</div>

Design-Build is characterized by a single point of responsibility for design and construction. Many owners choose Design-Build in order to reduce project-based risk. This risk is borne by the design-builder, in exchange for retaining any cost savings that are realized. Costing in the traditional Design-Build agreement is usually fixed early in the form of a Guaranteed Maximum (GMP) or lump sum. Project success is measured by improved delivery time or cost savings as compared to the agreed-upon Guaranteed Maximum Price. Linking compensation to project goals such as building performance, sustainability, and accelerated delivery can be used to promote greater collaboration and better outcomes.</div>

Design Bid Build is the most prevalent construction project delivery model in the U.S. and also here in the Middle East. DBB offers the owner the market advantage of a regimented design phase followed by separate bidding and construction phases. The project is designed with little input from the parties actually constructing the project. In many markets, and especially those with goverment mandated BIM, publically procured contacting requirements interfere with or prohibit early involvement by the Constructor. A Design-Bid-Build delivery model is somewhat antithetic to the goals of BIM and IPD.<br />
<br />
To alleviate these restrictions, owners may choose to tender the project at an earlier stage. The consequence of early bids is a loss in their accuracy and the necessity to accept bids with large contingencies. This strategy may also result in added amounts of redesign, requiring an adjustment to the designer's compensation.<br />
<br />
<b>IPD</b><br />
<br />
It has been eight years since the National AIA and its California Council published the guide to <b>Integrated Project Delivery</b>. Its introduction states, <i>"Integrated projects are uniquely distinguished by highly effective collaboration among the owner, the prime designer, and the prime constructor, commencing at early design and continuing through to project handover."</i><br />

</tbody></table>
The 2007 document was the impetus for development of LOD definitions and for the current AIA Digital Practice documents including Building Information Modeling and Digital Data Exhibit (E203).<br />
<br />
The guide contains reference to the now well-known MacLeamy Curve, which was first debuted in 2004. This graphic is famous to BIM users because it depicts the shift of effort which we know as "front end loading". The justification for the shift is the fact that effort is moved to an earlier stage, when the cost impact (risk) of making changes is less.<br />
<br />
In addition to shifting design decision making forward, redefinition of phases is driven by two key concepts: the integration of early input from constructors, installers, fabricators and suppliers as well as designers; and the ability to model and simulate the project accurately using BIM tools.<br />
<br />
Integrated Project Delivery does not <i>require</i> BIM. The 2007 guide states that "BIM is an evolving technology and is not used consistently in the industry at the present time." In the near decade that has passed since its publication, these statements about IPD have become the framework within which BIM users have strived to bring about change within the AECO industry.<br />
<br />
<i><span style="color: #660000;">Integrated delivery strengthens the project team’s understanding of the owner’s desired outcomes. IPD allows constructors to contribute their expertise early in the design process resulting in improved quality and financial performance. It allows the designer to benefit from early contribution of the constructor’s expertise, increasing the likelihood that project goals will be achieved.</span></i><br />
<span style="color: #660000;"><br /></span>
<span style="color: #660000;"><i>Integrated Project Delivery is built on collaboration, which in turn is built on trust. Trust-based collaboration encourages parties to focus on project outcomes rather than their individual goals. </i><i>Innovation is stimulated when ideas are freely exchanged among all participants. In an integrated project, ideas are judged on their merits, not on the author’s role or status.</i></span><br />
<span style="color: #660000;"><i><br /></i><i>Key participants are involved from the earliest practical moment. Combined knowledge and expertise is most powerful during the project’s early stages where informed decisions have the greatest effect. </i><i>The thrust of IPD is not to reduce design effort, but rather to greatly improve design results, streamlining the much more expensive construction effort.</i></span><br />
<span style="color: #660000;"><i><br /></i><i>IPD represents a behavioral sea change in the industry by breaking down the silos of responsibility, requiring close cooperation among all participants. The focus is on collectively achieving shared goals rather than meeting individual expectations. Success is measured by the degree to which common goals are achieved.</i></span><br />
<br />
Traditional contracting contemplates project participants operating within their own separate silos of responsibility. IPD seeks to break down these barriers by having all major participants focus on achieving shared goals. Most traditional construction contracts seek to limit the parties to whom duties are owed. In direct contrast, IPD proceeds under the theory that projects run more smoothly where all parties formally recognize what exists in practice – that every construction projects is a network of inter-linked roles, commitments and mutual promises.<br />

<div style="margin-bottom: .0001pt; margin: 0in;">
Greetings to All.<o:p></o:p></div>
<div style="margin: 0in 0in 0.0001pt;">
<br /></div>
<div style="margin: 0in 0in 0.0001pt;">
I am trying to
arrive at consensus with my colleagues regarding some aspects of our Standards
and Procedures for Revit.<o:p></o:p></div>
<div style="margin: 0in 0in 0.0001pt;">
<br /></div>
<div style="margin: 0in 0in 0.0001pt;">
Many Revit users
follow the practice of customizing content with a "company" acronym
to signify that the content is vetted to conform to office standards. <a href="http://bimaficionado.blogspot.com/2012/05/family-naming-simplified.html" target="_blank">My personal preference</a> is to precede each family type name with an acronym derived
from the family category, and I have now <a href="https://www.blogger.com/blogger.g?blogID=711812065588876537#editor/target=page;pageID=2336851029727413153" target="_blank">expanded the list</a> to include content
in all disciplines. I maintain that the presence of the acronym provides ample
significance.<o:p></o:p></div>
<div style="margin: 0in 0in 0.0001pt;">
<br /></div>
<div style="margin: 0in 0in 0.0001pt;">
However, in the
Project Browser, I contended that OOTB naming of standard content was
desirable. My view was countered with the argument that confusion may result if
other parties with whom we might collaborate used modified content with OOTB
naming.<o:p></o:p></div>
<div style="margin-bottom: .0001pt; margin: 0in;">
<br /></div>
<div style="margin-bottom: .0001pt; margin: 0in;">
One well-respected colleague has developed a naming strategy that
includes the prefix ‘AN’ for most annotations. I’m inclined to concede, but I
happen to disagree on the practice of ALL CAPS in the browser.<o:p></o:p></div>
<div style="margin-bottom: .0001pt; margin: 0in;">
<br /></div>
<div style="margin-bottom: .0001pt; margin: 0in;">
Again, most users follow the tradition of capitalization of sheet
names, however I would even question that practice. I believe it is a remnant
of old-fashioned CAD thinking, where the practice originated because of the
extension from hand drafting. (I was there.) ALL CAPS is generally avoided in graphic design and web design because it is harder (slower) to comprehend. There is some fairly <a href="https://www.digitalcookie.com.au/blog/writing-readable-content-and-why-all-caps-is-so-hard-to-read.html" target="_blank">consistent information</a> available to back this point of view.<o:p></o:p></div>
<div style="margin-bottom: .0001pt; margin: 0in;">
<br /></div>
<div style="margin-bottom: .0001pt; margin: 0in;">
I’d like to know what other Revit users have to say about these
options:</div>

Happy Holidays to all of my friends and associates around the globe.<br />
<br />
Christmas is not an official working holiday in the Middle East, but most of my coworkers have already departed, and I'm still here because I will be joining a few of my colleagues for dinner near the office.<br />
<br />
I recently returned to Qatar after a three week vacation in the U.S., encompassing Thanksgiving, Autodesk University, and an early Christmas celebration with my family. I was pleased to have met with several friends at the Las Vegas event, and the time spent at home was precious indeed.<br />

I have moved on from my role as BIM Manager of the Al Wakra FIFA 2022 World Cup stadium, having been promoted to BIM Manager of KEO's Architecture and Engineering Services division. I now occupy a nice corner cubicle in our Doha office with this view of one of the country's underground rail stations under construction.<br />
<br />
KEO has several BIM projects underway in our three main offices in Qatar, UAE, and Kuwait. I was invited to the BIM Leadership Forum at AUx Dubai, and will be presenting on BIM at the Future Interiors Conference January 20-21 in Dubai. We have recently organized the Doha BIM User's Group (D-BUG), Qatar's first ever BIM group, for which I will serve as chairman.<br />
<br />
Hopefully this change will facilitate my return to blogging, and I intend to focus on the unique situation which now confronts everyone involved in BIM and construction in the MENA region.<br />
<br />
I wish everyone a peaceful, happy and prosperous New Year. <br />

In the U.S., after two decades of development, Building Information Modeling has gained a fairly broad acceptance in most sectors of the AECO industry.There are many organizations involved in promoting and advancing BIM. Building Information Modeling is typical for large and complex buildings - airports, hospital & medical facilities, laboratories, schools.<br />
<br />
<span style="font-family: inherit;">In the beginning, BIM adoption was driven by professionals who quite simply wanted to improve quality, performance, and profit. In 2007 BIM adoption was boosted by the GSA National 3D-4D-BIM Program. Transition has not always been easy, and the level of implementation as well as methodologies vary widely, but today the top design firms in the U.S. are BIM firms: <i>Gensler, HOK, HDR, Perkins+Will, SOM, HKS. </i>Not coincidentally, the top construction firms have also invested in BIM: <i>Turner, Clark,
DPR, Hoffman, Hensel-Phelps.*</i></span><br />
<span style="font-family: inherit;"><i><br /></i></span>
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg56mZEdFDqkVORvc63LrGiNevL-4NqXBx78Tsmno4xKBM53oB2uZHDkmRBo2luLQYQWc8FYBOXy5y2xBafCT2OGq6iRencjVdwfu8FOOEFqpgy1NuMrIh2GdorV6nCMIfU8CObWfx_-3A/s1600/4609004740_d0e92df326_o.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg56mZEdFDqkVORvc63LrGiNevL-4NqXBx78Tsmno4xKBM53oB2uZHDkmRBo2luLQYQWc8FYBOXy5y2xBafCT2OGq6iRencjVdwfu8FOOEFqpgy1NuMrIh2GdorV6nCMIfU8CObWfx_-3A/s1600/4609004740_d0e92df326_o.jpg" height="175" width="320" /></a><span style="font-family: inherit;">Similarly, in the U.K., BIM adoption is being driven by the government sponsored Building Information Modeling Task Group. The 2011
Government Construction Strategy will require collaborative 3D BIM (with all
project and asset information, documentation and data being electronic) on its
projects by 2016.</span><br />

<span style="font-family: inherit;"><i><br /></i></span>
<span style="font-family: inherit;">The story in the MENA (Middle East & North Africa) region is not the same. Doha, the capital and largest city in Qatar, did not exist just fifty years ago, and it seems unlikely that many of the towers that have seemingly erupted from the desert were conceived using BIM. Even today, the new buildings currently being constructed are not exactly high tech, in terms of construction. They are reinforced concrete with block infill structures clad with aluminum and glass. They are </span>massively built and <span style="font-family: inherit;">labor-intensive and fantastic, but any evidence of BIM use is difficult to identify.</span><br />

<span style="font-family: inherit;">Qatar does have a National BIM initiative, which is an aspect of its <a href="http://www.gsdp.gov.qa/portal/page/portal/gsdp_en/qatar_national_vision" target="_blank">2030 National Vision</a> for growth and development following the FIFA World Cup in 2022. All of the major infrastructure projects and all of the 2022 stadiums are BIM driven projects. Familiar names like Atkins, AECOM, Jacobs Parsons and Turner are among those involved. Overall, however, the progress and development of BIM is far behind what we take for granted in the West. </span><span style="font-family: inherit;">Why?</span><br />

Nawar, BIM Coordinator at Arabtec Construction LLC, explains:</span><br />
<div class="MsoNormal" style="text-align: left;">
<span style="font-family: inherit;"><br /></span>
<span style="font-family: inherit;">Software
companies took the lead in introducing BIM to Middle East, as a set of software
and tools in the form of modeling, clash detection, quantity take-offs, and
drawing extraction. This has resulted in a huge misunderstanding of BIM as a
collaborative business process and limited the deployment of BIM in industry to
the usage of BIM tools.</span></div>
<ul style="text-align: left;">
<li><span style="font-family: inherit;">As
BIM is new to the region, qualified BIM specialists are rare. Accordingly firms
tend to hire and train people on using BIM tools without educating them on BIM
process.</span></li>
<li><span style="font-family: inherit;">BIM
requires significant sharing of data and information through the project life
cycle between internal and external parties involved in the project; however
companies in this region tend to be conservative and not so open to the sharing
of information</span></li>
<li><span style="font-family: inherit;">BIM
is a collaborative process that requires a major change in the internal work
process and culture.</span></li>
<li><span style="font-family: inherit;">BIM
(as it is meant to be!) is struggling to float to surface in this part of the
world. A conservative and limited form of BIM is starting to form in the Middle
East, a version of BIM limited to technology and capabilities of BIM software
and tools.</span></li>
</ul>
<span style="font-family: inherit;">Hamzeh
concludes, “Benefits are still realized with this version of BIM, but the major
benefits of a full BIM deployment are still a long-shot. Apparently BIM-ers
still have a really long journey to go before they start realizing the actual
benefits of BIM in Middle East.</span><span style="font-family: inherit;">”</span><br />

I've been silent for quite some time, but <a href="http://bimguruqatar.blogspot.com/2014/07/culture-shock.html" target="_blank">I've decided to start blogging again</a>.<br />
<br />
The reasons for the silence include immersion in my work as BIM Manager for the FIFA 2022 World Cup Al Wakrah Stadium and Precinct Development project, the intensity of that activity, and the observance the of the client's explicit interest in confidentiality. I am not allowed to share any of the details of the project, the processes involved in its creation, or detail the challenges that are typically encountered on any large and complex building project. I intend to comply with that mandate, no matter how much it goes against my professional and democratic sensibilities. Imagine where we would be with BIM if we could not share and learn from each other's successes - and failures.<br />
<br />

I can confirm that it is a BIM project with a high degree of complexity. I am on the Project Management team from KEO International Consultants. The project's architect of record is AECOM (London), the design architect is Zaha Hadid, and the client is represented by Project Management Consultant CH2MHill. Most of the professionals involved are British, along with Australians, a few Americans, and workers of many other Asian and European nationalities.<br />
<br />
Personally, there are always two aspects of my work-life from which I derive satisfaction, in addition to the actual objective activity of the job. Teaching and learning.<br />
<br />
In Qatar I have learned quite a lot, but so far the opportunities to "pay it forward" have been limited. The revival of this blog is one of the ways I intend to change that.</div>

<span style="font-family: Verdana, sans-serif;">In multi-family housing <i>CAD</i>, </span><span style="font-family: Verdana, sans-serif;">the design development process relies on surface modeler SketchUp. While most agree it is a "great design tool", the model is not connected to the plan development, and frequently loses its fidelity.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">Projects </span><span style="font-family: Verdana, sans-serif;">often receive client or agency approval in spite of inconsistencies. W</span><span style="font-family: Verdana, sans-serif;">hen a project moves from DD to CD, the 2D plan files developed by the designers are handed over to production staff who refine the building plans and develop construction documents. It is they who must decipher or verify the "design intent" while applying their knowledge of building codes and constructability. The redundancy and inefficiency in this process is apparent. </span><span style="font-family: Verdana, sans-serif;">The obvious solution is to use the same program for both modeling and plan development. That is the reason that BIM and Revit exist.</span><br />

<span style="font-family: Verdana, sans-serif;">The arrangement of the various unit types has significant impact on the building's form. Using mass families these unit types may be modeled as multi-story elements that can be driven parametrically to </span><span style="font-family: Verdana, sans-serif;">analyze </span><span style="font-family: Verdana, sans-serif;">and </span><span style="font-family: Verdana, sans-serif;">optimize the building design. Over time a library of </span><span style="font-family: Verdana, sans-serif;">plan types and plan forms will be developed that may be combined to rapidly complete the plan development. </span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>

<span style="font-family: Verdana, sans-serif;">Revit is very entrepreneurial, and even within the same company, there are often as many modeling strategies as there are modelers. Methods also vary depending on the type of project. My goal is always to improve both the process and the product. The knowledge gained will be applied to subsequent projects, regardless of type.</span><br />

Our largest <a href="http://bimaficionado.blogspot.com/2013/05/the-end-to-caddiction.html" target="_blank">BIM housing project</a> so far was <b>nearly derailed</b> during a
kick-off meeting with the owner's MEP consultants. I was not present (perhaps I should have been) but it was reported that
these CAD based designers were upset about the extra effort involved in working
with CAD files exported from a Revit model. One claimed that they would need to add 4 weeks to their schedule because of problems they have had with some other architect's BIM output. Of course this is just fear the
unknown - were have not yet provided anything. <i>(Owners take note - if the work were being done with BIM, this would be a non-issue.)</i><br />
<br />
It was stipulated that unless we can provide backgrounds and sheet
layouts that look exactly like our standard 2D files, the project will revert
to CAD. I did not hesitate to guarantee that will not happen. I further guaranteed that the export will be better than, not equal to, the typical 2D output.<br />
<div>
<br /></div>
Internally, we had previously discussed that the 'OOTB' Revit export setup
produces files that conform to the AIA Layer Standards, which is also the
basis for our office standard. To placate those who cannot seem to conceive of <b><a href="http://bimaficionado.blogspot.com/2012/09/core-only-walls-in-revit.html" target="_blank">walls with finishes</a></b>, we had further decided modify the export setup
to place the finish material line work on separate layers, allowing these
items to be hidden or deleted. <br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgb_OVa_HPK7_seUTnhgjFsMC1Uz5RjIFimAmR9pnUwqS0Ky7oMOa85vdsbKlImFXJZ5CDE7up4vozc2NQ0jFz-OQau7hU-Ur1JCaP0xKl1FegL_dKoqHZb1ne03bHe-JUbU4Sw1XtD2Wo/s1600/Layers.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="200" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgb_OVa_HPK7_seUTnhgjFsMC1Uz5RjIFimAmR9pnUwqS0Ky7oMOa85vdsbKlImFXJZ5CDE7up4vozc2NQ0jFz-OQau7hU-Ur1JCaP0xKl1FegL_dKoqHZb1ne03bHe-JUbU4Sw1XtD2Wo/s200/Layers.png" width="78" /></a>The main problem with <b>CAD standards</b> is they<span style="color: red;"> <b>DO NOT WORK</b></span>. We have a very well
documented office standard that defines layer names for every type of
"object" in the 2D world. We also have a table listing all of the
approved line colors and their corresponding line weights. I randomly chose one
base plan file from the project's "xref" directory and easily
discovered violations of both these "standards". Non-standard layer
names and colors.<br />
<br />
With the typical "x-clip/xref" methodology, there are
literally hundreds of layers to manage - one set for every instance of every
unit plan, plus many other random layers - more than six hundred layers in all.<br />
<br />
The CAD exported from the Revit model is completely consistent and reliable. The options for CAD export are explained very well by Steve Stafford in this <a href="http://revitoped.blogspot.com/2009/10/export-to-dwg-layer-options.html" target="_blank"><b>Revit OpEd post</b></a>,<br />
<blockquote class="tr_bq">
<span style="line-height: 115%;"><span style="font-family: inherit;"><i>"It is important to understand that the intended purpose
for exporting to DWG is to create files that can be used as a background for

I actually had to "dumb down" the standard export setup, combining items that would normally be on separate layers.<br />

For export to our specific office layer standard, line weights are controlled using color by layer:<br />

<br />
In the Visibility Graphics dialog, Cut Line Styles allows adjustments of lines weights of host objects (floors, walls, ceilings & roofs) which affect both display and export.<br />

Overall the output is better. 689 layers in a typical CAD floor plan base are reduced to thirty-one - yet CAD is the "industry standard" that is defended, against the elegant, simple, consistent output created by Revit.<br />
<br />
Strange but true.<br />

<span style="font-family: Verdana, sans-serif;">When I became immersed in the housing industry and began studying its
processes, </span><span style="font-size: 12pt;"><span style="font-family: Verdana, sans-serif;">my original strategy
for implementation was to emulate the methods being used with CAD, to make the
transition to BIM easier. That strategy has evolved over several months, and
each new project is an opportunity to improve the the process and the outcome.</span></span><br />
<span style="font-size: 12pt;"><span style="font-family: Verdana, sans-serif;"><br /></span></span>

<span style="font-family: Verdana, sans-serif;">Housing is similar to high-rise hospitality, where repetition of the individual
units within a structural bay is the key to efficiency, in the modeling process
as well as in actual construction. This repetition allows the unit mix within a
hotel or condo tower to be adjusted late in the design process, or perhaps
during construction, in response to project conditions. In tower BIM the
individual unit models typically do not include the building enclosure
(although this has been done).</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiyKkbytdVjH7R1CKY2o6LJOR-34s0W7n7vhgwwuSlty5fO9vV08tj2dfDDJfd8tgGUGSobBgtJfBHy_oMDwEqBSunZ2VSWIcbGVzx_Iy11TEAznu0jmcfjKjq_nBanqA61z2A0ShtxwTM/s1600/Units-2013.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="231" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiyKkbytdVjH7R1CKY2o6LJOR-34s0W7n7vhgwwuSlty5fO9vV08tj2dfDDJfd8tgGUGSobBgtJfBHy_oMDwEqBSunZ2VSWIcbGVzx_Iy11TEAznu0jmcfjKjq_nBanqA61z2A0ShtxwTM/s320/Units-2013.jpg" width="320" /></a><br />
<span style="font-family: Verdana, sans-serif;">Low-rise, Type V mixed-use and multifamily housing differs in that,
unrestricted by a structural grid, the unit shapes and sizes vary greatly, and
in design the pieces must be assembled like a jigsaw puzzle, to achieve the
desired unit mix. Within the individual unit types, there may be variations
based on story level or exposure, including windows, railings, balconies and
other interior and exterior features.</span><br />
<br />
<span style="font-family: Verdana, sans-serif;">In construction, these buildings are "stick framed" with bearing
walls, simple span floor joists, and roof trusses. They are very simple
buildings.</span><br />
<ul>
<li><span style="font-family: Verdana, sans-serif;">The <b>benefit of BIM to builders</b> is the refinement of the design to eliminate
surprises in the field. Surprises lead to changes, delays, and loss of
efficiency.</span></li>
<li><span style="font-family: Verdana, sans-serif;">The <b>benefit of BIM to designers</b> is that a building prototype may be rapidly
assembled with many variations tested to achieve the optimum design
configuration.</span></li>
<li><span style="font-family: Verdana, sans-serif;">The <b>benefit of BIM in production</b> is rapid composition of construction
documents that are coordinated and graphically consistent.</span></li>

<span style="font-family: Verdana, sans-serif;">
It is tempting to try assembling an entire building from groups or linked
files. While this is a great way to start, for a "stacked flats" project it must eventually be abandoned - <i>especially when using groups.</i></span><br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhE9QJhOduYFPMdKJ6rtQpxULVyPxd4_yLnRnrqqEF1fAE_qnj56IbMVN_fRXmjP1WDxsTX3-vx0ZGIhJ2-12MSGdgOc0Mh75pJDLHdk0aLBx2_9dpnuocliJ3WonWtKZlqPjt6lf4rXuE/s1600/Building+Group.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="264" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhE9QJhOduYFPMdKJ6rtQpxULVyPxd4_yLnRnrqqEF1fAE_qnj56IbMVN_fRXmjP1WDxsTX3-vx0ZGIhJ2-12MSGdgOc0Mh75pJDLHdk0aLBx2_9dpnuocliJ3WonWtKZlqPjt6lf4rXuE/s320/Building+Group.png" width="320" /></a><span style="font-family: Verdana, sans-serif;"><br />
A residential building's exterior walls vary in their height, materials, and openings. </span><span style="font-family: Verdana, sans-serif;">Once the basic form is generated, it seems best to remove these items from their groups. We start with "core only" walls for layout, but these are quickly replaced by components with specific materials and finishes.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">At the building level, the largest repeatable segment was identified as the entire building enclosure, consisting of roof, walls, floors, windows, doors, stairs and railings.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>

The key with these interior groups is that all objects must share the same reference level. Interior groups are independent; they <i>are not</i> nested into the larger building group.</span><br />

I was astonished when he projected ten more years before BIM would fully penetrate the profession. Already working on the bleeding edge of architectural technology for several years, that estimate was beyond my belief. <i>That was thirteen years ago.</i></span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">I visited <a href="http://philbernstein.typepad.com/phil-bernsteins-blog/" target="_blank">his blog</a> and was refreshed to learn that someone is thinking about architectural at a much higher level than is common in our daily professional lives:</span><br />
<blockquote class="tr_bq">
<em style="background-color: white; color: #232323; font-family: Arial, sans-serif; font-size: small; line-height: 19px;">"How do we make design a more profitable practice? Design practice has traditionally positioned building as a commodity in the delivery supply chain, valued by clients like other products and services purchased at lowest first cost. Intense market competition, sole focus on differentiation by design quality, and lack of innovation in project delivery models and and business models, has resulted in a profession that is grossly underpaid and marginally profitable, despite the fact the building sector in its entirety operates in large capital pools where significant value is created. </em><em style="background-color: white; font-family: Arial, sans-serif; font-size: small; line-height: 19px;"><span style="color: #990000;">The profession must explore new techniques for correlating the real value of an architect's services to clients and thereby break the downward pressure on design compensation."</span></em></blockquote>
<span style="font-family: Verdana, sans-serif;">This is the purpose of the <a href="http://bimmentors.wix.com/bim-4-homebuilders" target="_blank"><b>BIM-4-Homebuilders</b></a> conference. To learn what your colleagues and peers are thinking as well as what they're doing with regard to BIM. </span><span style="font-family: Verdana, sans-serif;">Those who have been to our SCRUG meetings know that the real purpose of the meetings is networking. At this event it will be on a grand scale, amid a 30 million dollar collection of exotic cars - and the proceeds of the event go to charity.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">Owners, designers, builders, and consultants all may have differing ideas about BIM. What is it? What does it do? What is it's value? What is it for?</span><br />
<span style="font-family: Verdana, sans-serif;">Why has this sector resisted change?</span><br />
<ul>
<li><span style="font-family: Verdana, sans-serif;">After a brutal economic downturn, workers are grateful to be employed, and reluctant to "rock the boat".</span></li>
<li><span style="font-family: Verdana, sans-serif;">It took years to get designers to give up their pencils - now they're stuck on Sketchup, the "hollow" modeler. Most designers show no interest in advancing the technology. Most are simply waiting to be told what to do.</span></li>
<li><span style="font-family: Verdana, sans-serif;">Practitioners have streamlined the CAD process beyond efficiency to minimalism. "We don't show that on our drawings" is a common instructional phrase. Coordination is one direction: downstream. It is up to the consultants to keep their work up to date. Conflicts are resolved in the field.</span></li>
</ul>

<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">My part in all this is to teach - to anyone who will listen - how easy, how satisfying, and how rewarding it is to build with </span>BIM<span style="font-family: Verdana, sans-serif;">. All the work depicted in the video above, and much more, was accomplished in two days time. Wall and floor types; custom windows and awnings, materials. Coordinated civil data; imported topographic data. As of today the first wave of design refinements has been implemented. </span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">We proceed with the confidence that all of this information is coordinated and up to date. </span><span style="font-family: Verdana, sans-serif;">We are gradually accumulating a library of components and prototypes, and a repertoire</span><span style="font-family: Verdana, sans-serif;"> of methodologies, that must eventually be moved upstream, to realize its full value. </span><span style="font-family: Verdana, sans-serif;">Those who resist are likely to be overwhelmed. </span></div>

<span style="font-family: Verdana, sans-serif;">At the end of its design development phase, a current project hangs in the balance between CAD and BIM. This study was commenced in an attempt to influence the direction of that decision. </span><br />
<span style="font-family: "Verdana","sans-serif";"><br /></span>
<span style="font-family: Verdana, sans-serif;">The "GA" Apartment pro</span><span style="font-family: Verdana, sans-serif;">ject was earmarked as a possible Revit/BIM project several weeks ago. Because of its impending launch into the CD phase, it was important to formulate and test the intended methodology for the accomplishment of that task using Revit.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">A breakthrough concept that
has evolved over the last several projects is the understanding that the
highest efficiency can be gained by modeling the largest repeatable segment of
the building. On this type of project, it is the entire "stack" of
units of the same type.</span><br />
<div>
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj6c-RMF3ep287bbCs-89fYpGQbZJOgtVkxSjqtfhnqQGNTR4RL5nzbaGg5-Rde1P5LiyezFoEdw9NJDYqIRbIbVs-or1x8kwWrFJE4ALIMFAwgzMxxLgm4F9HZXInvab45zRanTtNob8s/s1600/Unit+Types.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="220" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj6c-RMF3ep287bbCs-89fYpGQbZJOgtVkxSjqtfhnqQGNTR4RL5nzbaGg5-Rde1P5LiyezFoEdw9NJDYqIRbIbVs-or1x8kwWrFJE4ALIMFAwgzMxxLgm4F9HZXInvab45zRanTtNob8s/s320/Unit+Types.png" width="320" /></a><span style="font-family: "Verdana","sans-serif";"><br /></span>
<span style="font-family: "Verdana","sans-serif";">A review of the project reveals that
there are only six distinct unit types, and that these unit stacks occur in 2,
3, 4 and 5 story configurations. The interior of the units are identical on
every level, while the building exterior envelope may vary based on story level
and interior or end condition.</span><br />
<br />
<!--[endif]--><span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif; mso-bidi-font-family: "Times New Roman"; mso-bidi-theme-font: minor-bidi;">A <i>variable
height</i> mass component family was created for each unit type. This is simply
the unit footprint, extruded vertically. Each family is color-coded. When
placed in a massing model, these height of these components may be varied
parametrically. A complete massing model may be quickly assembled by placing
these 3D families, and filling in the interstitial spaces for circulation and
other services.</span><br />

<span style="font-family: Verdana, sans-serif; mso-bidi-font-family: "Times New Roman"; mso-bidi-theme-font: minor-bidi;"><span style="font-family: Verdana, sans-serif;">These components, of course, contain basic area
and volume data which may be scheduled. Over time, a library of the many
variations that are generated during design will be assembled, reducing
repetition and further accelerating the project development process. </span><o:p></o:p></span><br />

the creation of the stacked unit model. For this exercise the most typical unit
type was selected. The mass family is loaded into a separate project file.
Walls, floors, and roofs are created by selecting the faces of the massing
model. Next, doors, windows, decks and railings are added. Objects that repeat
from level to level are grouped for consistency and efficiency. Roof slope is
assigned and parapet walls are extended vertically. Finally exterior materials
are specified.<o:p></o:p></span></span><br />

<span style="font-family: "Verdana","sans-serif";">There is no debate about the value of Building Information Modeling. That has been realized for many years by countless practitioners on projects of all types. </span><span style="font-family: Verdana, sans-serif;">BIM is the obvious choice for design and construction professionals whose goals include the delivery of accurate and well coordinated contract documents. This can, of course, be achieved with the current system, but only with a high degree of discipline involving knowledge that has nothing to do with architecture. BIM assigns that responsibility to the software program, and allows users to focus on their specialty, whether it be management, design, or production. A small percentage of owners and builders now require BIM, but its benefits accrue to every project stakeholder, regardless of their level of knowledge or participation.</span><br />

<span style="font-family: "Verdana","sans-serif"; mso-bidi-font-family: "Times New Roman"; mso-bidi-theme-font: minor-bidi;"><span style="font-family: Verdana, sans-serif;">BIM can be used solely for production, but the maximum benefit comes from moving its application "upstream". For most homebuilding architects, the design work flow involves Sketchup and CAD. The main flaws of this methodology are that the models are hollow and contain no volumetric data; secondly, it (again) requires great discipline to keep the two programs in sync, until the goal is eventually abandoned.</span></span><br />
<span style="font-family: "Verdana","sans-serif"; mso-bidi-font-family: "Times New Roman"; mso-bidi-theme-font: minor-bidi;"><span style="font-family: Verdana, sans-serif;"><br /></span></span>
<span style="font-family: "Verdana","sans-serif"; mso-bidi-font-family: "Times New Roman"; mso-bidi-theme-font: minor-bidi;"><span style="font-family: Verdana, sans-serif;">The mass modeling capability of Revit is equal to Sketchup, and in the process described here, leads to a rapid and efficient development process, and an accumulation of resources which are easily accessible across all studios, offices, and project types.</span></span><br />

The tool is intended to do a slightly different job, and so it may not fit into your hands in just the same way.</span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Verdana, sans-serif; font-size: 12pt; line-height: 18px;">In residential projects with multiple buildings, whether single or multi-family, one of the expediencies forced by CAD is that every instance and variation of every building is not fully documented. </span><span style="font-family: Verdana, sans-serif; font-size: 16px; line-height: 18px;">There is a ripple effect throughout the drawings. Changes must be followed through. And this is where the weakness of CAD becomes too obvious to ignore. It is extremely inefficient when it comes to the minor adjustments and fine tuning of the drawings. And so we do not do it. Because of CAD.</span><br />

Instead we frequently refer to someone else's drawings, and it's up to the builder to put it all together in the field.</span></div>

The minimum standard is a four inch step and two inches of slope (one percent). </span><br />

<span style="font-family: Verdana, sans-serif; font-size: 12pt; line-height: 18px;">In single family, the step-down may be increased to adapt the building to a sloping site. </span><span style="font-family: Verdana, sans-serif; font-size: 12pt; line-height: 18px;">With larger buildings, in addition to the garage step-down, sometimes the entire floor slab must be offset, or even the entire building. Although these decisions are not within our scope, we are required to depict this information on our drawings.</span><br />

<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">In CAD, where accuracy is often pushed aside for expediency (because it's so inefficient?) these values have been "leveled off" to 9'-1", 10'-2", and 19'-3".</span></div>
<div>
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<div>
<span style="font-family: Verdana, sans-serif;">Also in CAD, reference values from finish floor are rarely given. The plate to sub-floor dimension is also excluded. </span><span style="font-family: Verdana, sans-serif;">The logic (?) being that at the start of the job, the floor assembly depth is unknown, and CAD must be protected from the demand for changes, where it is extremely inefficient.</span></div>
<div>
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<div>
<span style="font-family: Verdana, sans-serif;">When modeling with Revit, the best practice is to use actual values whenever they are known. </span><span style="font-family: Verdana, sans-serif;">There are no "unknowns" in a Revit model. The model is a record of all the information gathered about the building being designed. What better place to record those decisions <i><span style="color: #990000;">accurately </span></i>than in a Building Information Model?</span></div>

<span style="font-family: Verdana, sans-serif;">Practitioners who wish to see no "differences" between CAD and Revit may set the dimension tolerance "to the nearest inch" and exclude the values from the level annotations.</span><br />

<span style="font-family: Verdana, sans-serif;">There is no substitute for accuracy. </span><br />
<span style="font-family: Verdana, sans-serif;">When using Revit, do not attempt to substitute an illusion for reality.</span></div>

Eventually three different users spoke about their procedures regarding central and local files, and all of them were different from mine.<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiE0QZ_sWtj7tywlGF6Z8p6T9YI4MeHX38Vp1kMjBdY8YaYhO6fkEKzikieXS6S-ZXnazydR6EwkDZs13JdsoJ4h80RmuPH-9UlpamrK-TbJDYeyfVuwSqKQz_GGRCI4oPn4z7722GRmLo/s1600/Worksets.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="143" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiE0QZ_sWtj7tywlGF6Z8p6T9YI4MeHX38Vp1kMjBdY8YaYhO6fkEKzikieXS6S-ZXnazydR6EwkDZs13JdsoJ4h80RmuPH-9UlpamrK-TbJDYeyfVuwSqKQz_GGRCI4oPn4z7722GRmLo/s200/Worksets.png" width="200" /></a>Revit Worksharing was introduced in version 4 (2002?) and represented the first true multi-user BIM environment. With this innovation, all objects in the model were assigned to a collection; the "workset", which was required to be checked out by a single user. Conflicts still arose when an objects in different Worksets interacted with each other. These limitations eventually led to the development in version 6 (2004) of "element level borrowing", which lessened the need for Worksets, except on larger projects.<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhbrKj1IdKhDV69c8F15jTf8oi7aBX58ofL8EbkD36aPf7IYh09EJ3H5jNUSu62LPgTNSOS3sXSJHuRgbHQWTjf1ENnddrz5ur-3Bj72AAuE7piJ92BVyM8xSBhSd3l8mwhZlNLJZFkclE/s1600/Worksharing.png" imageanchor="1" style="clear: right; display: inline !important; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="137" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhbrKj1IdKhDV69c8F15jTf8oi7aBX58ofL8EbkD36aPf7IYh09EJ3H5jNUSu62LPgTNSOS3sXSJHuRgbHQWTjf1ENnddrz5ur-3Bj72AAuE7piJ92BVyM8xSBhSd3l8mwhZlNLJZFkclE/s200/Worksharing.png" width="200" /></a>When Worksharing is activated, the single user file is automatically converted to a central file. Copies of the new central file are automatically designated as "local' files which must be periodically synchronized with the Central.<br />
<br />
When this feature was initially implemented, all file management was manual. It was not unusual for inexperienced users to accidentally open the central file; one solution was to include the word 'central' in the file name, as a reminder.<br />
<br />
Another common problem was the failure to save local changes back to the main file, locking other users out. This led to the so-called "best practice" of creating a new local file every day or even with each new work session. These protocols were originally all manual, and some users created external programs to automate the process.<br />

Some CAD users have developed the habit of browsing to a file and "double-clicking" it in Windows Explorer (which is fine for single user files). When users open a Revit central file by this method, or any other, they will soon receive a warning to save their work into a new local file.<br />
<br />
<i>As with CAD</i>, when using Revit there is no reason maintain some strange attachment to procedures that have become obsolete. The Zen of Revit means developing a sense of "what Revit wants" and following it.<br />
