Design-Assist / Design-Build
EAS delivers best-in-class results on some of the industry’s most technically demanding projects through a collaborative, integrated approach. By engaging key design and trade partners early in the preliminary design phase, our Design-Assist / Design-Build process drives consistency, predictability, and performance from concept through commissioning.
What is Design-Assist / Design-Build?
Design-Assist / Design-Build is a delivery model centered on early partnership and shared accountability. EAS joins the project team during design development to align the mechanical scope, cost, and constructability. Through collaborative modeling, prefabrication, and precise coordination, we streamline design decisions, accelerate installation, and eliminate surprises in the field.
​
Our goal: Increase predictability with the team, cost, and schedule; delivering certainty where it matters most.

Featured Project: Confidential Pharmaceutical Client
EAS was the mechanical contractor for this leading confidential pharmaceutical client and a member of the IPD project team. EAS worked with engineer, owner and other key trade partners to provide pre-construction design, Full BIM modeling and coordination and competition of mechanical scope of work. As part of the IPD process, EAS worked to identify cost saving measures to reduce project budget. schedule, off-site construction, alternate materials, and labor savings.
