Project Plan and Spec

Plan Your Mechanical Contracting Project With QuesTec

Although we are not always low, we are almost always in the bottom third in bids ranked by price. Why can we do this? Simply because we have the most consistent systems, people and technologies to deliver efficient projects time after time.

In this traditional method of building, an owner hires an architect and engineer, and plans and specifications are sent out for competitive bids. The lowest qualified bidder is usually selected to build the job. This is the where QuesTec began to work. We cut our teeth on plan and spec work and have become one of the best at what we do.
