Design West Engineering Revit MEP Success Story

Autodesk released this latest success story of a company in California that is using Revit MEP. Clients ask me if companies are using this software all the time, and I tell them yes. Not only all over the US, but locally as well. Some companies don't want to be on the leading edge, but we are getting to the tipping point where more companies are using Revit than thinking about using Revit. The key is having a good strategy and a progressive team and support from upper management.

With Revit® MEP software, Design West Engineering completes construction documents for the SEA LIFE™ Aquariumat LEGOLAND®.



Design West Engineering Customer Success Story
Revit® MEP Revit®
For our clients using Revit Architecture, our original
goal was to produce 100 percent of our construction documents with Revit
MEP and we’ve already accomplished that. It really does help us run a much
tighter project and put a better product into the field. The 3D models give the
entire design team — from the project engineer on down — adramatically improved
understanding of the building. As a result, contractors can build our projects
more easily and with far fewer questions.

Firm Summary
Design West Engineering is a mechanical, electrical, and plumbing (MEP) engineering consulting firm based in San Bernardino, California. Established in 2000, the firm delivers services to clients from a wide range of building sectors, including higher education, K–12 schools, religion, and civics. “We’ll tackle almost any type of commercial engineering or energy-efficiency project,” says Robert Cronk, a principal at the firm. “Lately, we’ve also done quite a bit of multifamily residential work.” Until early 2007, Design West relied primarily on AutoCAD® software to deliver exceptional service and designs to its architectural partners. “However, we began to notice that more and more architects were using Revit Architecture software and becoming quite passionate about wanting to collaborate with us via a complete building information model.” As a result, Design West began migrating to Revit MEP software, the intuitive building information modeling (BIM) solution built specifically for MEP engineers and designers.

The Challenge
Since adopting Revit MEP, Design West has completed construction documentation on 14 major projects, including the 28,000-squarefoot SEA LIFE Aquarium at LEGOLAND near San Diego, California. “SEA LIFE is designed to introduce children to the wonders of the ocean,” says Cronk. “There’s a whole chain of them across Europe, but this project is their first U.S. venture.”

“The whole park is very heavily themed, with lots of exposed ductwork and piping that must be painted or covered with theming,” says Cronk. When designing SEA LIFE locations throughout Europe, the project architect used Revit® Architecture software. “However, because the MEP engineers on those projects were still using traditional CAD applications, they sent him 2D ductwork drawings. As a result, before the theming contractors could decorate any of the spaces, the architect had to provide interior elevations of every single wall in all of the attraction rooms so they could estimate the proper duct heights.”

Revit MEP provides instant design feedback— not a large set of error-prone documents for after-the-fact examination.

Architects are obviously concerned with aesthetics; our initial requirement is to make sure the system works properly. The Revit platform enables both of us to do our respective jobs better.

The Need for Speed
All of that work was time consuming and not very accurate. Yet the SEA LIFE project was on a fasttrack construction schedule and could not afford any delays or possible design errors. “We broke ground in late November,” says Cronk. “The goal is to have the project fully operational in late June and open to the public in time for the July 4 weekend.”

An Information Disconnect
“In the construction process, there’s often a disconnect between the information we provide the
architects and what they really understand about the ductwork systems,” says Jarrod Baumann, a project manager at Design West. “Often, we don’t resolve that disconnect until after construction begins. With Revit MEP, we hope to greatly increase the architects’ understanding of our projects long before we get to the fi eld. We want them to know exactly where our ducts are going to run and how they’ll interact with a building.”

The Solution
Right from the start, Revit MEP and its intuitive tools for system design and analysis enabled Design West to save valuable time. “The principal architect was absolutely tickled to receive our 3D Revit MEP model,” says Cronk. “He used Revit Architecture to cut a section from every single wall and quickly get all the information the theming team needed to do its job.”

Reduce Design Conflicts
“He was also able to interactively check to make sure no future confl icts existed,” says Cronk. “We already knew that we didn’t have any confl icts with the building structure, but he was able to verify that there would be no problems with the theming and the ductwork. That was a very big benefit.”

Easily Visualize MEP Designs
“Revit MEP also enabled the architects to easily visualize our designs,” says Baumann. “Architects are obviously concerned with aesthetics; our initial requirement is to make sure the system works properly. The Revit platform enables both of us to do our respective jobs better.”

Create More Accurate Designs
“Because the architects can easily see where we want to place a unit, how big it is, and what it looks like, we can quickly make adjustments based on their input,” says Cronk. “Plus, the Revit platform itself gives us instant design feedback rather than a large set of documents that someone has to carefully examine for accuracy much later. That helps us make better decisions and increases the likelihood that our MEP systems will fi t the building in the best possible way.”

Increase Understanding
“As a result, we’re starting to see that the architects have a much better understanding of our discipline,” says Cronk. “To give a specifi c example, one of our clients does a lot of multi-family residential work with Revit Architecture. Those types of buildings have very tight space constraints on the mechanical systems. Using our model, the architects easily produced shafts and soffi ts for ductwork right around the work we gave them. They absolutely loved this capability.”

Build Credibility
“Another benefi t is added credibility with the architects,” says Cronk. “Sometimes it seems as if they think we’re crying wolf when we ask for more duct space. With Revit MEP, we can quickly show them exactly where all of the space is getting chewed up. The whole interaction is more efficient and we’re able to move forward that much faster. That’s a huge benefit.”

Share a Common Model
Design West also worked closely with the SEA LIFE project’s structural engineers. “More often than not, if we have a problem fi tting the ductwork on a project, it involves the structural cavities,” says Baumann. “We used Revit MEP to determine whether we had enough space for ductwork or adequate clearance in various spaces throughout the entire project.”

Clearly Communicate Design Intent
Even on a much smaller scale, Design West has found tremendous benefi t in Revit MEP software’s 3D visualization capabilities. “For example, we recently designed a small retail space,” says Cronk. “The owner was interested in how the different displays were going to look. He was very pleased to be able to sit down in front of the 3D model, interact with it, and see exactly how the space and diff erent light fi xtures would appear in real life.”

Reduce Costs
“Based on what he learned in that meeting, the owner made signifi cant changes to the light fixtures,” says Cronk. “Because he also received some budgetary feedback from the model, he decided to cut costs by changing some of his lighting selections.” Design West also helped one of its architectural clients, WLC Architects, save money on the design of its new 60,000-square-foot offi ce building. “Using the information in our Revit MEP model, the architects were able to determine the actual cost of several different lighting packages and make appropriate budgetary decisions,” says Cronk. “They also chose the fi xtures that looked best in the space.”

Practice Green Design
“That particular offi ce building is going for LEED certification,” says Baumann. “As a firm, we’re
involved in several other sustainable design efforts, such as the Collaborative for High Performance Schools (CHPS), a spinoff of LEED focused primarily on schools. Currently, we’re designing a combination high school and middle school campus. The client wants to score incredibly high on the CHPS checklist and plans on using the Revit platform to accomplish a substantial portion of that.” In particular, Design West is experimenting with exporting geometry from Revit to various software packages for heating/cooling and lighting analysis, such as eQuest, IES Virtual Environment, and AGI 32, either with direct export/import or through GBXML.

Transform Attitudes
Revit MEP software’s 3D capabilities have had a profound impact on contractors. “One of our project managers recently presented 3D designs to a contractor who’s been building multifamily residential homes from 2D documents for more than 20 years,” says Cronk. “At first, he wondered why we’d even bothered to use 3D.”

Maximize Coordination
The fi rm’s ultimate goal is to receive very accurate structural models at the same time that it receives the architectural models. “That really enables us to do our jobs well,” says Baumann. To further minimize design coordination errors on the SEA LIFE project, Design West regularly updated its model via links to the architectural building model, the structural framing model, the aquarium tanks, and the underground tanks.

Intuitively Create MEP Systems
“At one point on the SEA LIFE project, we got into a real time crunch,” says Cronk. “The owners made dramatic changes at a time when we had pressing deadlines on other projects. Because our entire offi ce wasn’t yet trained on Revit MEP, I produced some of the immediate changes in AutoCAD to get us past the hurdle.” Later, when engineers input Cronk’s changes into the Revit model, they quickly noticed several ways to improve the AutoCAD-produced design. “Being able to spin the model on-screen made me feel like I was at the job site discussing ways to save money with the contractor,” says Baumann. “Using Revit MEP, it’s easy to take that kind of step in the office— long before getting to the field.” “But by the end of the meeting, he had to admit
that it really helped him visualize the lighting for the parking lot and courtyards,” says Cronk. “He also admitted that 3D would be even more helpful to someone without his skills. Even with his level of experience, he still thought that 3D was worthwhile— even if it required extra effort.”

Improve Workflows
As a direct result of using Revit MEP, Design West modifi ed its workfl ow in several important
ways. “For one, our project manager and Revit trainer is very quickly moving into the role of BIM manager,” says Cronk. “His job is to oversee the quality and content of the model and to make sure that it works across the entire Revit product family— throughout our office and with our partners.”

Subscribe for Maximum Benefit
After receiving early training at Autodesk University, Design West chose to participate in the Revit MEP subscription program. “There’s definitely a benefit to being able to keep up with the latest release,” says Cronk. “We also get access to additional helpful information and quick responses from the online product support team. Our subscription has been very useful to us; we certainly don’t intend to do it any other way.”
The Result
“We’re really excited,” says Cronk. “Our original goal was to produce 100 percent of our construction documents with Revit MEP for our clients using Revit Architecture and we’ve already accomplished that. It really does help us run a much tighter project and put a better product into the fi eld. The 3D models give the entire design team—from the project engineer on down—a dramatically improved understanding of the building. As a result, contractors can build our projects more easily and with far fewer questions.”


Gain Competitive Advantage
Our marketing director says that the best thing he can tell
an architect is that we use Revit MEP. We’re currently really well positioned in
the marketplace and have a distinct competitive advantage—particularly because
most other MEP firms can’t provide these services yet. We wouldn’t have that
advantage without Revit MEP.

Setting Up Default Fittings To Be Used In Revit MEP

You can create and set up a number of different Duct Types and Pipe Types in Revit MEP by editing the properties of those Type families. Within these various Duct/Pipe Types that you create, each type can have their own default fittings that you will use for that Type. The key though, is to make sure that the correct fittings that you want to use are loaded into your project. If the correct fittings are not loaded into the project, you will probably not get the results you are looking for when laying out duct/pipe.

Once you set your Duct and Pipe Types, save those into your project template so that you can reuse those types and fittings for future projects. This will save you time and allow you to do more designing and less setting up.

To set up your pipe types, select a type in the project browser down at the bottom under families, and right-click and duplicate it and rename it with your new name. Then right-click and change the properties. Within the properties dialog box, you can change each fitting that that pipe/duct type will use by default when laying out a system.





Each type can be unique and have different fittings. This speeds up the design process because Revit MEP will automatically place the correct fitting based on the Pipe/Duct type you are using when laying out your routing. You shouldn't have to manually place fittings very often.






This goes not only for manually routing pipe/duct, but also for the automatic layouts that are generated. When you have Revit MEP layout a system for you, in the Settings, you can choose what Pipe/Duct type you want to use, and Revit MEP will automatically place the fittings that you choose to be the defaults for that Pipe/Duct Type.



If you go into the Mechanical Settings under Settings Pull Down menu, you can also create your own piping materials and assign Roughness and set the connection type and assign sizes for your own custom pipe. You can then assign other pipe properties in your pipe types to these custom pipe materials and settings.

Rectangular Duct - Tap - Beveled Revit MEP family

Kyle to the rescue again. Revit MEP has a lot of Duct Fittings and Pipe Fittings. They may not all be loaded into the default project template, but you can load them in from your Imperial Library.
If you haven't noticed yet, it is missing a Rectangular Beveled Tap.




(From Kyle)

This one has all sorts of bells and whistles, as I got engrossed with
fixing it one afternoon, and my trig hand was strong that day. It adheres to
SMACNA standards OOTB (Takeoff Length = 0.25 * Duct Width, 4" Minimum), but allows you to override both the length and the angle if desired, so this is
really all that you need. To accomplish this, there are a bunch of nested IF
statements that drive the dimensions, have fun going through it if you'd
like.

Below are some picks of some ducts that I connected using the Rectangular Beveled Tap Fitting.

From the AUGI thread, and if you an AUGI member, you can download this family by going to the link I posted.

On a side note, I loaded every Duct Fitting, and every Pipe Fitting from the Imperial Library in a template project, to see how large a file it would create, and the template project file was just under 20 meg with nothing modeled yet.

[Request for Feedback] Pipe Naming Conventions

Kyle Bernhardt with Autodesk Revit MEP's team is requesting participation in a survey to help them define how best to name Pipe Fittings by end users.

Kyle writes on his blog (Inside the System):

I wanted to solicit your participation in a survey we have developed involving Pipe Fittings, and how you as users think about them.

Pipe Fittings are a complex beast when it comes to describing them in a short concise manner. Many aspects about them, such as Material, Class, Type, Connection Type, etc., are factors for selection in a design.

We'd like to know more about what is important to you as users, so we can define a convention that best reflects that feedback.

With that in mind, I ask that you please fill out the following survey to provide us your perspective on this matter. It shouldn't take more than 5 minutes.

For those of you who are CAD Managers, I would request that you ask your end-users to fill out the survey, as they will most likely be the folks most directly impacted by choices that we make.

Thanks in advance to all of you.

Taking Advantage of View Templates

View Templates are preset view properties for your project or for your project template. You use view templates in your project to set views up quickly and to make sure that your views are consisitent with other views in the project. You do not want to be changing these view settings everytime for every view that you create in Revit MEP, but rather you would just apply a view template to a view. These view templates can be included in your project template or used in other projects using the Transfer Project Standards option and selecting View Templates as one of the objects to transfer.




Once you set the view scale, the visibilty/graphics settings, the discipline, the sub-discipline, and other view parameters, you can save those settings as a view template to apply to other views.


You can create this view template from an existing view by right-clicking on a view in the project browser and Create. Then you apply this view template to another view by right-clicking on a view in the project browser and Apply.



You might have multiple views on one sheet. You can apply one view template to multiple views at one time by right-clicking the sheet in the project browser, and Apply View Template to All Views. Once you open up the dialog box, you can clear the checkbox of any property that you don't want all the views to include. So if you don't want all the views to have the same scale, and retain the scale that was set in the original view, then you can clear the view scale property.




While you are applying a view template to a view, you can select the "Show Views" check box. This will show you all of the other views in the project that are of that type, and you can set your current view to the settings of another view without having to create a view template.
