Many contractors can claim design/build capabilities. Dunbar takes it to a new level in design/build with:

Superior Project Management
Our ISO certified processes prove it—you’re getting more with Dunbar. We have perfected out Project Management systems to control, manage, track and report all project details. Over 80 percent of the savings in every project is built in during Dunbar’s planning process. While planning is stressed at the beginning of every job it is actually a continuous process with routine schedule updates. Our systems can provide schedules in as detailed as 15 minute increments for exceptionally fast projects including shut-downs and change-over's.

Advanced cost control methods
Saving you time and money isn’t a by-product. It is the product. Our cost accounting methods are second to none in procurement, tracking, justification and forecasting. Tracking is a daily task with a commitment to providing itemized breakdowns of budget vs. actual vs. cost to complete reporting for your use. You will know where we stand on the project and have hard facts to use in your cash flow projections as well. Our accounting group provides all of this information to you on a real time basis.

Unprecedented project delivery
From initial planning to our production manufacturing process—right through to final punch-list close out, Dunbar’s project delivery efforts are unsurpassed. Just one part of our process is our Material Status Report which tracks equipment ordering and delivery dates plus the submittal process for reviews and approvals. This report documents Dunbar’s process which ensures nothing is overlooked as projects proceed. You can see your project before we build it through our CAD proficiencies and BIM processes. Dunbar’s Design/Build benefits continue in the outstanding work of our Fabrication facility AND, most importantly, in
your operation.
