-- Building Design & Construction, 9/8/2009 8:28:00 AM
A newly released guide from ASHRAE on building information models and building information modeling (BIM) serves as a resource for professionals considering BIM tools and applications for their businesses.
According to "An Introduction to Building Information Modeling," BIM is “a digital representation of the physical and the functional characteristics of a facility.” Unlike 2D or 3D CAD, BIM software utilizes intelligent objects to create models.
The benefits of using BIM applications are numerous, including enhanced interoperability, which will improve integrated building design and integrated project delivery (IPD), according to Dave Conover, a member of the BIM Steering Committee who wrote the guide. Most important, however, is BIM’s ability “to create an accurate model that is useful throughout the entire life of the building, from initial design through occupancy and operation.”
Conover feels that, in addition to the actual benefits of the BIM process, the guide itself offers advantages in that it gives those unfamiliar with BIM “a fast and high level introduction.” He went on to explain that even those already familiar with BIM could benefit from downloading the guide: “It provides some broad level insight into how BIM will affect the building industry in general.”
In addition to BIM’s advantages and tips for getting started with the application, the guide also includes a list of helpful software so that engineers might choose the best program for their company.
An Introduction to Building Information Modeling is available as a free download on ASHRAE’s Web site at www.ashrae.org/publications .
ASHRAE, founded in 1894, is an international organization of some 50,000 persons. ASHRAE fulfills its mission of advancing heating, ventilation, air conditioning and refrigeration to serve humanity and promote a sustainable world through research, standards writing, publishing and continuing education.

I just got done verifying an process that I've heard mixed issues that result if your workflow process is not correct when using Revit MEP. And it's great news in my opinion.
When you place plumbing fixtures in your Revit Model, it is placed in the Default System.
You can connect multiple plumbing fixtures to each other with pipe, and get all the wonderful flow information - all without adding those fixtures to a specific system that you create. If you select the pipe and look at it's Instant Properties, you can not only see the flow going through those pipes, but you can see that it has a "System TYPE" of Domestic Cold Water and a "System NAME" of Default Domestic Cold Water. Make sure not to confuse the two.
The default View Filter displays System Types of Domestic Cold Water in a blue color. So everything looks good, but there is a limitation of how many plumbing fixtures you can connect to each other that are put on the Default System Name. And that limitation is 50 fixtures.
Below is a thread from Jason Martin at Autodesk explaining the history of this Warning further:
One of the things that is most expensive in the “calculation process” is maintaining the “pressure losses” in sections of a duct or pipe system. To do yhis we divide any connected system into sections at any junction or size change in the system (there are additional reasons for a section to be created, like a resistance change, and I’m sure a few others). For each of the sections we track things like pressure loss, static pressure etc. Maintaining these types of calculations for relatively small sets of elements is relatively inexpensive compared to the time it takes to do things like actually move the things. In systems with thousands of elements, however, these calculations became exponentially more expensive as the element counts increase. We decided at that point that when there are more than a set number of “system assignable-1” elements assigned to a system that we would turn off these types of calculations. After quite a few rounds of testing (as well as some arguing) we decided that a “tolerable” number of elements to turn off these “complex” calculations at was 50. So, now, as soon as the number of elements in a system goes above 50 you’ll get an error message that says something like:
“The default system "Default Supply Air" is now over 50 elements. To improve performance, Revit is no longer calculating the critical path pressure drop and the more complex duct sizing has been disabled. If you want to use these features, you must define logical systems in the model instead of using the default system.”
If you receive this error message it doesn’t have anything to do with things not updating in elevations / sections, and it doesn’t make the application automatically disconnect things. In versions prior to 2009 WU3 (or whichever one it was) it was very true that creating systems improved performance “massively”. Since the introduction of the “50 element” rule, it isn’t as significant as it once was.
For other “performance” things, it really, really, really depends. In 2010 a significant portion of effort was spent on improving the performance of what we referred to as “model manipulation”. This includes things like dragging, connecting, moving, sizing (either with sizing tools or just changing the size), and deleting items like pipe, duct and fittings. As a few others have mentioned here, “model manipulation” in 2010 is significantly faster than it was in previous releases.
If you are moving a connected duct / pipe / fitting - our internal testing has shown that it is actually “slightly” faster to not have systems defined than it is to have systems defined. If you are making new connections between things - our internal testing has shown that it is actually “slightly” faster to have systems defined than it is to not have them defined. If you are changing the flow of elements in the system (like air terminals) - it is “slightly” faster to have systems defined than it is to not have them defined. If you are creating systems - it is significantly faster to create them before things are connected with ducts and pipes.
System assignable elements are things like air terminals, mechanical equipment etc. Things that when you select them you see a create system button (or edit system button) but don’t include things like ducts, fittings, pipes, etc.
Which brings me to the name of the article, Don't Go Half Way. I hear a lot of firms that just want to model certain parts of the building in Revit, and do 2D for the other in AutoCAD. Or they want to just create a 3D model, and not use the flow calculation tools that Revit has. But there are a lot of things going on in the program that if you're not aware of, you run into these limitations such at connecting 50 elements to a default system and you end up creating more headaches than you thought you were going to avoid by taking shortcuts. So go the extra step and create the systems and use them to your advantage. You can save so much more time accepting the full Revit process the way it is supposed to be used, than trying to come up with workarounds and unproven processes of how Revit is not supposed to be used.

Models Contain Geometry and Data To Improve All Phases of Construction
The rapid adoption of 3D design tools and building information modeling (BIM) software represent profound challenges and opportunities for the architecture, engineering and design professions.
The potential is that tools like Autodesk Revit® and Bentley MicroStation® will help specifiers create structures that are more sustainable, deliver productivity improvements during design and construction, and provide greater value to owners even faster.
And, in this new era, one of the significant challenges is that specifiers don’t have access to a full and accurate library of 3D models for all of the products that go into a construction project.
Acuity Brands Lighting (ABL) is working with the design community to help improve the promise of BIM by providing 3D models of its lighting products.
Architecture, design, engineering and construction professionals can find a starter set of 3D models of Acuity Brands most popular luminaries on this site. These models will allow designers to seamlessly integrate lighting into project, saving both time and money as they eliminate the guesswork about how the lighting look and interact in the built environment.
This initial set of products is only the beginning. ABL will continue to add more 3D models to our library each month so that designers have access to an ever-growing selection of innovative lighting products.

These Revit families are 2009 version.
The families are not the smallest files. They are a bit large. (900k typically). But if you don't have a lot of them, you could make due.
The Taco families are parametric, and there are hundreds of files, one for each pump and they contain all of the data associated with the pump.
There is a Type Catalog TXT file for each Taco family. Make sure that file is in the same location as the family itself.
You can download an entire pump family as a zip file, but then each pump is in another zip file, so you need to unzip each pump, and like I said, there are hundreds of them. Otherwise you can download them on the fly as you need them from Autodesk's Seek site.

PHOENIX--(BUSINESS WIRE)--Greenbuild Expo 2009--Autodesk, Inc. (NASDAQ: ADSK), a world leader in 2D and 3D design, engineering and entertainment software, announced that building product manufacturers including Reilly Windows & Doors (Reilly) and Mestek, Inc., are successfully using the Autodesk solution for Digital Prototyping to collaborate with the building information modeling (BIM) process and architecture, engineering and construction (AEC) firms.
By providing “BIM-ready” product models that can be directly incorporated into the building design and construction process, product manufacturers help AEC firms make better design decisions around constructability, fit, aesthetics, performance and cost, while increasing their own ability to win new business.
With the growing adoption of BIM in the building industry, AEC firms are increasingly requiring 3D, BIM-ready models from manufacturers as part of the acceptance criteria. Autodesk Inventor software gives building product manufacturers the ability to create digital prototypes of their products and then publish simplified 3D representations with intelligent connectors and product information as BIM objects. These 3D representations can be consumed by the Autodesk Revit suite of products, which are purpose-built BIM applications designed for architects, engineers, and construction professionals. BIM-ready models can also carry important information about a product’s green characteristics, providing early insight into potential LEED certification.
Digital Prototyping as a Competitive Advantage
Reilly designs, fabricates and installs custom windows and doors that exceed the expectations of even the most exacting clients. To create elegant, high-quality products, Reilly relies on a Digital Prototyping workflow based on Autodesk Inventor software to design, visualize and simulate its products digitally and to deliver models of its products to architects who use Autodesk Revit Architecture software.
“Delivering 3D models to architects is a huge value, particularly because most architects can’t spend time creating realistic models of windows and doors,” said Michael John Iwanyczko, director of marketing at Reilly. “We’re offering them highly detailed 3D models that they can incorporate into their architectural designs — it’s another level of service that sets us apart.”
Mestek, Inc., is a family of more than 30 specialty manufacturers providing heating, ventilating and air conditioning (HVAC) products. For more than 40 years, the company has focused on creating a superior indoor environment for building occupants through its offerings. The company recently started using digital prototypes created in Inventor software to develop BIM objects and currently has a published library of more than 300 objects that can be downloaded directly into Revit models.
“The ability to reuse our digital prototypes and repurpose that data to create BIM objects is very important for us, especially since our products tend to be complex and highly configured,” said Mike Kaler, general manager of Mestex, a Dallas-based subsidiary of Mestek. “Sharing these BIM objects with the architects and engineers provides tremendous time savings since we don’t have to create the content from scratch again.”
“Autodesk’s established presence in both the AEC and manufacturing markets is enabling more effective communication and collaboration between disciplines,” said Robert “Buzz” Kross, senior vice president, Manufacturing Industry Group at Autodesk. “Using Inventor software-based solutions allow building product manufacturers to go beyond 3D to Digital Prototyping, and it allows our AEC customers to leverage digital prototypes in their Revit-based BIM workflows.”

Julian Kang, associate professor and graduate program coordinator, Texas A&M University, www.tamu.edu, College Station, Texas, had a clear reason for wanting to host a BIM (building information modeling) forum in Houston—to talk about everything the industry can do with BIM, specifically in the construction phase of a project.
Three years ago, Kang did a BIM investigation as part of research efforts for the AGC (Associated General Contractors of America), www.agc.org, Arlington, Va., and found general contractors in the Houston area did not clearly understand how much they can accomplish using BIM.
When he met George Pontikes, chairman of the board, AGC Houston Chapter, and president and CEO, Satterfield & Pontikes Construction, www.satpon.com, Houston, Texas, Kang brought up the idea of offering a BIM forum in Houston, and coincidentally Pontikes had a similar idea. With a program committee, Kang and Pontikes began making decisions and promoting the first BIM forum in Houston.
The BIM Forum Houston 2009, http://bim.tamu.edu/, took place Sept. 17, 2009 and had roughly 90 people in attendance. The event focused on BIM issues and trends in the construction phase of a project. With two keynotes, six breakout sessions, two interactive presentations, and a panel discussion, the event was full of best practice stories and emerging technology.
While one keynote—reported by the AGC—focused on the current economic situation, it was the other keynote—from the Texas Facilities Commission—that garnered a lot of attention, according to Kang.
Recently, the FDC (Facilities Design and Construction Division) within the TFC (Texas Facilities Commission), www.tfc.state.tx.us, Austin, Texas, adopted BIM for state design and construction projects, in an effort to standardize the use of BIM in future projects.
Texas is not the first state to develop a set of BIM standards and guidelines for all partners involved in a state project. Earlier this summer, the Division of State Facilities in Wisconsin prepared BIM guidelines and standards, which were implemented on July 1.
Chris Tisdel, director of building information modeling, TFC, presented the keynote at the BIM Forum Houston.
“He is one of the courageous guys in the construction industry who is preaching the benefits of BIM in construction as an owner,” says Kang. “So, if you want to get a project from the State of Texas, you have got to use BIM.”
Tisdel even talked of specific applications that should be used. According to Kang, Tisdel is asking companies working with the State of Texas to use Revit Architecture from Autodesk, www.autodesk.com, San Rafael, Calif. At the forum, contractors learned about the state’s BIM template for project team members and learned how to incorporate BIM into the lifecycle of projects.
Kang says Tisdel presented many benefits of the standards and guidelines including interoperability, reducing redundant work, and sharing information with others on the team.
“He is basically talking from the owners’ perspective. He wishes to have some central repository where he can get all kinds of 3D models—in this case Revit models—of all buildings that was awarded by the State of Texas,” says Kang.
Another hot topic at the forum was the use of COBIE (Construction Operations Building Information Exchange) to continue to use BIM even after the construction is over.
According to the National Institute of Building Sciences’ WBDG (Whole Building Design Guide), www.wbdg.org, Washington, D.C., COBIE simplifies how work is captured and exchanged. The approach is to enter the data as it is created during design, construction, and commissioning. While it is intended to work within the BIM process, the data can also be exchanged using spreadsheets. Many attendees focused on COBIE and how to use the building information model for facilities management.
Kang says overall event and attendee response exceeded his expectations and he is planning to expand the program next year—beyond just Houston.
“I guess what I would like to say is next year’s forum is … going to be a forum for everybody in Texas,” says Kang. “It is a forum for people that want to see more BIM coming to the construction industry.”
Autodesk Navisworks BIM models, synchronized through LATISTA, contain information for quality assurance (QA/QC), collaboration, production tracking, and materials tracking on the jobsite and in the construction office.
Reston, VA (PRWEB) October 7, 2009 -- LATISTA Technologies, a leader in construction automation and field management solutions, announced that LATISTA Field automation software has integrated Autodesk Navisworks project design and synchronized BIM modeling capabilities. Autodesk, Inc., is a provider of computer aided drawing (CAD) and building information modeling (BIM) software.
LATISTA Field was developed specifically to be used on the jobsite with portable tablet PCs. Now it includes Autodesk Navisworks BIM capabilities to improve collaboration between the office and the jobsite.Combining LATISTA Field's mobile and web-based solution with comprehensive Navisworks models enables owners, architects, engineers, and construction professionals to update, access, and share information on a single construction model on and off the jobsite. LATISTA Field is leading the way in linking BIM technologies to the LATISTA Enterprise quality and field operations management solution.
To improve efficiency and accuracy, LATISTA integrates information from the Navisworks model and augments in LATISTA Field it with statuses, issues, and actions for automating field operations including quality assurance and control (QA/QC), materials tracking, production tracking, punch list and commissioning.
Our software is already proven to reduce a construction project's time and cost. Adding Autodesk's BIM information into LATISTA and enabling project teams and owners to view LATISTA information in Navisworks only compounds the return on investment for our customers.
With a mobile tablet PC in the field, a LATISTA user can key in or scan the item's tag code from RFID or barcode and status the item. Back at the office, the Naviswork model is automatically updated with the latest statuses from the field, generating an instant up-to-date view of the project's progress. Project teams and owners benefit from having a visual representation of the latest information from the field, since shared information leads to less confusion and fewer delays.
"Our software is already proven to reduce a construction project's time and cost," said Chris Ramsey, Executive Vice President of LATISTA, "Adding Autodesk's BIM information into LATISTA and enabling project teams and owners to view LATISTA information in Navisworks only compounds the return on investment for our customers."

NVIDIA further refines its graphics cards
Oct 1 2009 12:17PM
By Jeff Yoders
NVIDIA released its 10th generation of professional graphics cards earlier this year. I was given a test NVIDIA Quadro FX 1800 with the HP Z600 workstation for a test drive earlier this year. Here’s a more detailed look at the Quadro FX 1800, a mid-range professional graphics card that would be a good fit for any architecture or engineering firm looking to upgrade its graphics cards with or without new hardware.
The Quadro FX1800 has 756 megabytes of onboard memory, two digital display iutputs, and one DVI output, all in a PCI Express interface. The card does not require a separate power connector from your computer’s power supply. While the Quadro FX1800 is listed as a top mid-level card, it’s really the minimum anyone doing heavy CAD or using even the most basic BIM programs should have. Only NVIDIA itself manufactures the Quadro line, so the company can guarantee quality and performance. (Its GeForce consumer line of cards has much more tolerant production specifications and therefore can be outsourced to other manufacturers around the world.) All Quadro cards are certified to run on Windows, Linux, and Mac OS.
Thanks to its partnerships with software manufacturers such as Autodesk and Adobe, NVIDIA makes sure that every Quadro card passes minimum requirementsbefore shipping. Working with AutoCAD 2010, Revit, and Navisworks Manage 2010, my Quadro FX 1800 was ready to use upon installation with the latest Autodesk drivers and also optimized to take more of the workload off my test machine’s processors. The NVIDA Application Configuration Engine, included with every Quadro card, automatically adjusts graphics settings for optimized application performance from the start, eliminating the need to manually adjust settings for different applications.
I noticed the 50% more graphics memory that the Quadro FX1800 boasts over the last generation of NVIDIA cards for interactive visualization of large assemblies and scenes. (The Quadro FX 1500 was used in the HP xw4600 I tested last year.) One test of performance was done by opening multiple large models created in both Revit and AutoCAD. The graphics card was able to significantly speed up the process of opening and viewing the large files. The test took about twice as long on the older machine.
The NVIDIA Quadro FX 1800, easily removed
from my PC with no tools.
One welcome improvement in the card’s interaction with AutoCAD 2010 is higher image quality with AutoCAD Smooth Lines. Any card can render a generic line, but will it produce the smooth, high-quality lines that AutoCAD demands? Usually not. That used to lead to only two choices: sacrifice line quality for the sake of performance, or fall back to software rendering and live with the inevitable drop in frame rate. Professional-class cards like the Quadro FX 1800 integrate a fast hardware engine specifically designed to draw AutoCAD-style smooth lines. The aesthetic lines we drew had the desired level of detail with no drop in frame rate, thanks to the card’s processing power.
The Quadro FX 1800 is an excellent solution for any AEC firm looking to upgrade. The out-of-the-box optimization and GPU acceleration for software partners is a huge timesaver for IT departments, too. More than half of NVIDIA’s engineers are actually software engineers, so years of work actually went into making the Quadro FX 1800 this easy to use.
The Quadro FX 1800 is a mid-level graphics card optimized to perform with today's most popular design programs, including
SolidWorks and AutoCAD.

Apparently, even Building Information Modeling is bigger in Texas. The Texas Facilities Commission announced yesterday that it is requiring a BIM m..."
Building information modeling (BIM) is the process of generating and managing building data that can be used from the planning stage, through construction, and well into all stages of a building’s life-cycle. Typically, it uses three-dimensional, real-time, dynamic building modeling software to increase productivity in building design and construction.
Drafting’s Evolution to Building Information Modeling
When computer-aided design (CAD) was introduced, it brought a new dimension to creating line drawings. Rather than needing a compass or triangle, one could type a command, and a circle could be drawn in any size and any scale. A line could be given any length or angle. Even with the slow speed of early computers, copying and deleting could happen at a pace only previously imagined. Building layouts could be changed much more quickly than on the drafting board.
However, this speed came at a price. When plans were designed on the drafting board, architects and engineers met before the building design started to coordinate mechanical room sizes, water heater locations, electrical panel locations, etc. All members of the design team focused on completing the project with as few changes as possible.
Building information modeling software has developed as the next step in CAD’s progression. BIM software has taken the approach of creating the model within a database. This allows higher functions to be applied through the use of parameters. Parameters can input more information than units of measurement. They can be used to apply text, graphic overlay for rendering, and referencing information from other databases. The entire model has the ability to be parametric. Rather than lines representing a pump, the pump now has become a virtual object with the ability to contain real-world information such as plan location, elevation, weight, volume, horsepower, pressure loss, and much more (see Figure 1).
The ability to contain a wide variety of data types gives the BIM program the ability to perform calculations and display the information in multiple views in real time (see Figure 2). Several different products on the market today are used to create BIM models (see sidebar).
HOW BIM Will Change Plumbing Design
When a company decides to commit to BIM, the plumbing designers will be tasked with learning the new software to produce their designs. The company may need to invest in new computer hardware to run the software effectively. The transition will require training to use the software and might require more time to develop content. This endeavor can take six months to a year before plumbing personnel actually become efficient.
The International Code Council is in the process of developing new standards to incorporate BIM in the code review process. This new project is called SmartCodes. This can have a major effect on plumbing design if plumbing designers and engineers are not involved in the development of this process. There have been numerous discussions about how industry societies need to be more involved in the development of plumbing standards. I believe BIM can be a catalyst. Within BIM’s format, plumbing calculations can be produced to help show building sustainability. Plumbing engineered systems then would have more credibility. (If you would like to learn more about SmartCodes, visit www. iccsafe.org/SMARTcodes.)
Advantages of Using BIM in Plumbing Design
Coordination with other disciplines always has been at the top of our list when designing a system. Being able to work in a virtual 3D environment really helps detect conflicts. Most BIM solutions have a means of performing conflict detection and will highlight the areas in question. Since BIM solutions are normally databases, the ability to track items such as mechanical equipment, plumbing fixtures, fixture unit counts, and gas loads is much easier. Creation of the final documentation is quicker. BIM models normally contain parametric objects, and information can be added to adjust the physical attributes of these objects. If any piece of information needs to be scheduled, a parameter can be created to allow the object to share information with a schedule.
The 3D view of the BIM model can be rotated to different directional planes to produce plumbing isometrics (see Figure 4). Since most BIM software creates the model using databases, streamlining construction specifications can be done through third-party software such as e-Specs. Cost estimating for plumbing systems becomes more accurate due to the requirement for a more accurate layout within the BIM model. Most BIM software allows CAD files to be imported and models to be exported to CAD so other groups that are not using BIM can coordinate.
Disadvantages of Using BIM in Plumbing Design
Training on the MEP portions of these solutions is very hard to find due to the specialized nature of our fields. Some engineers also state that the quality of contract documents is not as good as CAD-produced documents. The linetypes that contain text styles that currently are used in CAD are not available in some BIM programs. Also, when a designer is routing piping inside a vertical
wall cavity from a section view, the floor plan view may not show the single line piping correctly. However, this will improve as these programs mature.
The main objective of BIM is to produce a more accurate representation of the building and all of its components, thus providing better engineered systems. More time is required to lay out an accurate BIM model in plumbing due to all of the virtual pipe the designer is modeling. If proper workflow is not followed, results can be untimely delays or increased change orders. Most of the plumbing content for these solutions, such as objects for traps or valves, must be created due to the current development stage of BIM software, which can be very time consuming.
Also, if other disciplines are using 2D CAD, coordination becomes much more involved because the plumbing designer no longer can take advantage of designing in the 3D environment and cannot run any automated interference checks, increasing the chances for error and liability due to the accuracy of the model.
Tips for Using BIM Successfully in a Project
First, research what product would best suit your needs. Have vendors send a trainer to demonstrate how their software works. A good test is plumbing two water closets with cold water, sanitary, and vent. Ask others about their experience, cost impact, training requirements, and vendor software support. Ask the vendors about the computer system requirements to run their software. Since most modeling software programs are databases, the system requirements are much greater than that of standard business class machines. BIM software requirements can affect the network infrastructure of your office. Upgrading to a BIM software package is like buying an old house—do your homework and research and be prepared to do a lot of repairs and customizations.
When you finally decide what software you will be using and have updated your computers to handle the software, make sure to purchase proper training. As stated earlier, training seems to be hard to find when looking for plumbing solutions for BIM. BIM software can be self-taught, but the learning curve can be very steep. Vendors normally recommend searching online for forums dealing with the software package that you have chosen. The personnel chosen for training should have a positive attitude and specific experience in your type of design work.
Once training is complete, start developing a template containingyour company’s standards. This template will continue to evolve as you develop more content for other projects. Converts much information from CAD as possible to your BIM software and, if time allows, create this information from scratch. When trying to import information from one software to another, databases can become unstable or corrupt.
When you are ready to start using BIM on a project, it is preferable to select a pilot project, such as a small job that can take a loss. Don’t use BIM for the first time on a project with a short deadline. This can be counterproductive and can ruin morale. When your pilot project is complete, make a list of things that did not work properly and a list of things that did work properly and use this as a benchmark for your next project. As your team develops their skills, the list of issues will grow smaller, and your team will have the confidence to complete any project.

elements) takes too long and is cumbersome to say the least. Fourth, opening a project in Revit takes a considerable amount of time. Fifth, setting up sheets is cumbersome. Sixth, there’s not enough flexibility in the final presentation. Next, changing symbology to match a company’s standard is time consuming and in some cases impossible. Program bug fixes are slow to nonexistent. The software company has time to add content but not enough time to go back and fix
what doesn’t work. It seems their interest lies in creating content just good enough so they can advertise that it does more to get companies to buy a ‘new’ and ‘improved’ version. Lastly, creating the information in elements so you can use the dynamic schedules is too cumbersome.
“I think 2D is more stable and faster (therefore cheaper for the client) to use. Unless you have a client that insists on BIM, wait about 10 years to buy it until it becomes useful. As a bare minimum, quadruple your time estimates for project completion in BIM versus 2D CAD.”

“On the other hand, it can be quite tedious at times and very time consuming. The more work you have on your model, the longer it takes to regenerate. I haven’t had a lot of formal training, so there can be a steep learning curve. The out-of-the-box fixtures are not good. You have to look around forums and websites to get the fixtures and fittings you need or create them yourself.
where the line work can get busy, space is tight, and coordination is paramount.
“For example, there was a corporate office building that we just completed. Revit certainly helped when it came to the coordination with the structural beams. There was a restroom/locker room in the basement garage, and there were beams overhead that pretty much boxed us in. By looking at various angles of the 3D model and sections, we could coordinate with the architect to get the furring and chases needed to get though the structure and avoid a possible RFI and/or change order.
“We use AutoCAD Revit because we felt it was the best for the overall firm. It offered the best local support.
“For example, in designing a 12-story hotel, the architect located some floormounted, tank-type water closets over a corridor below. By looking at the section, we realized that the architect had only allowed 9 inches of ceiling space for the corridor below. If we weren’t already looking at that section to check the pipe and fittings, we may not have caught this ceiling space issue as early as we did. Also, on the same project, because of the amount of work and pipe in a hotel, the model became so large that it would take a minimum of 15 minutes just to open the drawing. At one point it took almost an entire day to draw one storm line from a roof drain down to below the slab and out the building. As more information is put in the model, the slower it gets. Eventually the file crashed, and all work from the previous day’s backup had to be exported to AutoCAD to be able to complete the project on time. As I previously stated, BIM is great for coordination but awfully slow in the real world.”

“We use Autodesk Building Systems. We already use AutoCAD extensively, so this was the easiest transition. We are currently testing Revit MEP but are not convinced of its capability for piping design.
