Design-Assist-Build (DAB)

Bolander partners with owners, architects, engineers, and general contractors from the earliest design stages. Our senior management and field operations staff help build constructability, cost certainty, and schedule efficiency into your project before it breaks ground.

Why Design-Assist-Build?

  • Enhanced cost certainty: Early involvement produces realistic, accurate budgets.
  • Fewer change orders and RFIs: Field issues are solved on paper, not after mobilization.
  • Improved safety and quality: Field expertise makes designs practical and safe to build.
  • Faster delivery: Early procurement of long-lead items and compressed schedules.
  • Seamless integration: Our systems are designed to fit your site plan, sequencing, and team.

How It Works

Phase 1: Collaborative Design and Preconstruction

Phase 2: Constructability, GMP Budgeting, and Scheduling

Phase 3: Construction Execution
