Our Design-Build Process

The key to our proven design-build process is a detailed project design and construction schedule, featuring seven key phases

Preliminary Schematic Design

Our design team will work with the project owner and other key project stakeholders to determine comfort requirements, building constraints, energy considerations and other important project details. The discussion of these requirements contributes to our recommendations for preliminary mechanical and electrical system options.


Our in-house estimating group will work with the design team on budgeting a variety of mechanical and electrical systems. We’ll use this information to develop clear, realistic project budgets and system energy pay-backs.

Engineering & Design

Our engineers and designers develop mechanical and electrical system designs informed by our preliminary analysis and created with the latest building analysis and digital design tools.

Building Information Modeling (BIM)

Our in-house staff will transform mechanical and electrical system designs into a comprehensive 3D building model for improved design coordination, accurate material and equipment procurement, and efficient system constructibility.


The project management team will work closely with the design team to ensure a smooth transition from design to construction.


Our project managers, installation crews, and fabrication staff will ensure your project’s budget and completion deadlines stay on track.


Our technicians and applications engineers will ensure your systems operate as designed and at peak efficiency.
