Design / build is our preferred method of contracting.  This is a collaborative process closely partnering you, the owner, together with your design team member to determine the best, most economical design.  Typically, the key to design / build is the integration of the site and building designs.  To foster this relationship, the owners of A. P. Williams, Inc. founded Mainline Excavating, Inc. in 2000 and Williams Site Civil in 2017.  With our vast field knowledge, practical experience and cost / value understanding of both the sitework and building construction, A. P. Williams, Inc. can be a powerful asset to you throughout the design process. 

Most often, the design / build team is working toward a specific budget.  At various times throughout the design process, we will solicit competitive bids from local subcontractors and suppliers.  We then work together with you and the design team to review those bids and select our project subcontractors and suppliers.  Using this process, you can more clearly understand the construction budget from an owner's perspective and make more informed decisions if adjustments to the project scope are mandated to meet the established budget.

Another great advantage of having your contractor involved during the design phase is that this will naturally eliminate the potential for many of the change orders that often arise on competitively bid projects.  This offers you increased peace of mind that our project budget is solid.  The design / build process implemented by A. P. Williams, Inc. eliminates costly design inefficiencies while affording you the essential insight needed to make critical decisions between design element and budget constraints, resulting in the best, most cost effective design that your budget will allow.
