As design-builder, Petra assumes the design, budget, and construction responsibility for the owner. Petra contracts directly with the architect, engineers, and consultants to develop drawings, provide a guaranteed maximum price, and and then build the project.

The design-build approach allows for early collaboration where all team members work together through the beginning stages of the project, with each bringing their design and/or construction expertise into the mix.  Getting everyone together early allows all team members to share their ideas for creative and innovative solutions, which can lead to faster project delivery and best cost value.

This system is used to minimize the project risk for an owner and to reduce the delivery schedule by overlapping the design phase and construction phase of a project.
