Design Assist is the procurement method by which, prior to completion of design, a construction contract may be awarded on a best value basis pursuant to which a contractor provides design assistance to the architect or engineer of record through a design professional separately retained by the contractor.

Design Assist Professional

The role of the Design Assist professional (DAP) is to be an engineering representative of the installing contractor (IC) throughout the design phase of a project. The (DAP) becomes an integral active member of the design team and is the installing contractors link into the design process. It is imperative that the (DAP) understand the intent of the system design, the project factors, and the decisions that are influencing the system design as created by the Engineer Of Record (EOR). The (DAP) involvement begins at the SD phase of the project and shall be an active participate in all design charrettes and design team meetings. The DAP will involve the means and method, cost estimating, and scheduling experts of the (IC) in the appropriate design meetings.
