Dunbar Mechanical offers Building Information Modeling.

See a 3-D version of your project before construction begins.

Dunbar's commitment to be your  contractor is illustrated well through our Building Information Modeling (BIM) system. (What is BIM?) When you build with Dunbar Mechanical, you benefit from our state-of-the-art services which are among the most progressive in the industry. Dunbar Mechanical was one of the first, and remains a leader, in implementing BIM technology.  Dunbar brings true value by working with you and your design team to ensure your concept is efficiently constructed. This systems approach allows us to completely serve your needs, from walking through the facility before it is built to providing you with 3-D “as built” drawings. Dunbar's BIM services guide the fabrication production process and later become a complete and accurate record for your ongoing operational reference. BIM is more than a technology at Dunbar. We have made it a process for project success, identifying and correcting discrepancies before installation.

Dunbar Mechanical performs Building Information Modeling (BIM) utilizing AutoCAD® compatible 3-D modeling software, NAVISWORKS®. Dunbar Mechanical ties our BIM capabilities to our fabrication process, making this a valuable tool to bridge engineering vision with construction.

Using Dunbar Mechanical’s Building Information Modeling (BIM) system, you’ll get to see the layout before we begin. Additional benefits of BIM include:

  • bimAll systems including mechanical, electrical, security and fire protection, can be shown at the same time.
  • The ultimate end user as well as designers and the construction team can take a “virtual tour” through the facility to assure the systems are constructed in the preferred manner.
  • Identifying discrepancies and resolving interferences BEFORE  installation minimizes costly change orders and field delays.
  • "Build it once" mentality improves construction team morale and productivity.
  • Cost and schedule data integration -- mitigating risk, managing costs and speeding delivery.
  • Complete as-built drawings are available electronically and on paper for easy reference.

The experienced professionals at Dunbar Mechanical would be pleased to provide your company with a computerized demonstration of our building information modeling which is a key component of our service.

The critical connecting point between the virtual world of BIM and actual field construction is the accurate measurement of existing conditions on site. Dunbar has recently employed Laser Scanning / Existing Conditions Surveys to help with our work as the Prime Mechanical for Life Support Systems in the renovation of The Toledo Zoo's Aquarium. This Works Progress Administration (WPA) building is undergoing a transformation and Dunbar is using the latest technology to ensure success.


What is BIM?

Building Information Modeling (BIM) means different things to different people. BIM can include a variety of
characteristics, including:

  • building information modeling toledoa more fully integrated project delivery method.
  • a 3-D model of portions of the project and/or the entire project.
  • a method of electronically sharing construction documents.
  • a method to efficiently assure systems will fit in the space allowed and detect potential system collisions.
  • A way to include the construction schedule and cash flow projections into the overall project plan.
  • An effective maintenance tool containing equipment data and as-built location information.

Dunbar Mechanical has already used BIM to implement these characteristics. Coupled with our team partnering culture and experience, Dunbar is uniquely qualified to participate in BIM projects. Below is another BIM example -- this is from Fremont Energy Center, a 720 MW Combined Cycle Power Plant in which Dunbar used BIM to self-route al small bore piping.

Dunbar Mechanical has been producing 3D models of our work since 1998 and offers an easy reference to our BIM capabilities by clicking here for a .pdf file.
