Constructech magazine | BIM in Specialty Markets

...and then there's this. All of the contractors and subs are getting into BIM. There's just no time left to train the 2D year olds when they finally realize they've missed the boat. Well, they are on a boat, it's just that it's called the Titanic and it's sinking fast. Welcome to a world where no one cares about line weights, hatch patterns or what font you used. Quite frankly, I've never met a contractor who's paid any attention to line weights. When exactly did that become so important.

I love AutoCAD. The more the architects and engineers keep using it, the more business I get from GCs and subs wanting to learn the BIM process so they can get the job done. Ho Ho Ho, Merry BIMness and Happy New Layer.

These days, CAD (computer-aided design) software is being more widely used across the construction lifecycle as a tool to improve productivity. Taking it a step further, the BIM (building information modeling) process is also being used by all parts of the construction project team—including specialty constractors.

According to Matt Firestone, chief estimator, Commonwealth Electric Co., www.commonwealthelectric.com, Lincoln, Neb., the biggest challenge specialty contractors face with regards to using BIM is a lack familiarity with the technology—primarily the fact so many people are focused on BIM just being a 3D rendering of a project.

“We are using Revit and MEP to do our BIM design,” says Firestone. “We are also actively educating the industry on the benefits of using it.”

With the models, the company is able to dissect the project into smaller working parts and pieces. Whereas before multiple sets of drawings were required on the jobsite, now the company just has one set of working drawings in the trailer.

More so than that, Firestone sees a big opportunity for seamless integration between Revit and its estimating system from McCormick Systems, www.mccormicksys.com, Chandler, Ariz.

According to Firestone, more specialty contractors should look to tie the data from the working model to other programs for estimating and scheduling, among others. This will help connect the entire construction lifecycle.

One upgraded product on the market comes from DraftLogic, www.draftlogic.com, Edmonton, Alta. Built on top of AutoCAD from Autodesk, DraftLogic Electrical is designed for electrical-systems contractors and engineers.

The technology reduces the time it takes to do repetitive calculations, which will allow the company to have more time to communicate with clients. Contractors can also create schedules, plans, and a bill of materials with conduit, wire, devices, and switch gear quickly.

Recently, DraftLogic showcased integration between DraftLogic Electrical and ConEst, www.conest.com, Manchester, N.H., IntelliBid. This means estimators can import device counts from DraftLogic Electrical into ConEst’s IntelliBid.

This type of integration between CAD and estimating software will ultimately help the construction industry reduce the amount of rework that needs to be done on a construction process, allowing contractors to focus more on the customer’s needs.
