Design-Assist & Design-Build Mechanical Services

Especially in today’s economy, tighter schedules and leaner construction budgets are par for the course. As a result, more Bay Area project owners are considering the design-assist and design-build mechanical construction delivery methods to help them make the most economical and effective use of time and materials.

When time is of the essence, the Peterson team can drive a quick schedule through fast-track material procurement, creative scheduling, overtime, and special shifts. We employ the latest CAD, CAM, and BIM technologies to help finish projects faster and reduce the risk of cost overruns.


Peterson’s design-build capabilities ensure turnkey mechanical systems while maintaining the project budget, schedule, and energy management plan. Our in-house engineering team will take the mechanical portion of the project from pre-planning through start-up and commissioning.

Analysis of System Alternatives & Lifecycle Cost

Peterson will provide you with multiple system options and conduct detailed economic analyses of design alternatives to determine payback periods.

System Selection

Using target value design (TVD) and budget validation, we will help you select the systems that meet your project’s budget, performance, and energy conservation goals.

LEED® Certification

Our in-house LEED Accredited professionals will target the appropriate LEED credits and meet all necessary requirements to achieve your desired certification level.

Energy Modeling

We use the latest technology to build, run, and tune whole building energy models for engineering economic analysis, LEED Optimize Energy Performance credits, and Title 24 documentation.

Code Compliance

Our team will provide expert analysis of all current building codes, including CALGreen, NFPA, and local codes. When necessary, we can prove alternate means of code compliance (variances) to reduce project costs.


The design-assist delivery method is an effective way to reduce project costs and control schedules while maintaining the traditional separation between contractor and consulting firm. Our engineers, project managers, detailers, and estimators will work with your design team to produce fully coordinated and constructible design documents. By identifying value-engineering opportunities, we can help you make the most effective use of resources while meeting performance goals.
