Design-Bid-Build

The Design-Bid-Build (DBB) or ‘Hard Bid’ approach is a traditional delivery method commonly used for publicly funded projects. In this procurement method, an architect is contracted to produce complete construction documents. Upon completion, the documents are then ‘bid out’ to often a minimum of three General Contractors. Typically, the low bid is then reviewed for accuracy by the Design Team, presented to a council or board members for approval, and then a notice of award is issued to the General Contractor. Certain opportunities allow for value engineering, which Harper looks forward to. However, a typical DBB project minimizes design collaboration in favor of a faster start to the schedule and little to no shared cost savings among the project team.

Historically, infrastructure, municipal, and education projects regularly required design-bid-build procurement. However, these sectors are beginning to adopt alternative delivery procurement methods like Construction Management At-Risk or Design-Build to utilize the General Contractor’s knowledge and resources during the design phase and enhance design collaboration and savings opportunities.

What People Are Saying

“Woolpert was the Design Engineer for the City of Aiken’s 3MGD Silverbluff WTP. Harper was the successful bidder on the job and was awarded a 3.6 million dollar contract to perform the construction. Since day one, Harper approached the project with a team mentality offering Value Engineering suggestions as well as successfully collaborating with the Engineer, Owner, equipment suppliers, and sub-contractors to keep the shop submittal process and construction operations moving forward. The project was completed, 7 months ahead of schedule.”
