Federal Design-Build Services

Ameresco is a full-service engineering and construction firm offering design-build services.

Our expert in-house capabilities include engineering, architectural and design services, programming and planning, estimating, construction, construction management, and construction administration services.

We have successfully delivered projects for facilities under design-build, design-bid-build, design-build plus, design-bid-build, and bid-build contracts. Ameresco holds contracts to provide engineering, procurement and construction services on a site-specific, regional, and nationwide basis, and has performed under routine, rapid response, and emergency situations.

Ameresco regularly takes responsibility for the proper coordination and execution of design-build projects as prime contractor, including:

  • Overall design development, project management, and construction management
  • Maintaining strong lines of communications with our subcontractors
  • Design and construction quality control
  • Prioritizing workplace safety and ensure all subcontractors comply with our safety plans
  • Maintaining project schedules including any corrective actions if there are unforeseen changes
  • Managing multi-million dollar project budgets
  • Overseeing proper start-up and commissioning of the installed systems

In-House Quality

Ameresco has developed well-established procedures to ensure consistency, quality, safety, speed, and contract compliance in our management of design-build projects. Our experience is punctuated by delivering on time and on budget. Successful implementation relies as much on effective project management as it does on a sound technical approach. Our project teams consist of designers, engineers, and construction personnel to self-perform engineering, procurement, and construction management, as well as quality assurance and commissioning. We bring industry leading expertise to the coordination of multi discipline projects.
