Design-Build & Design-Assist Services for Commercial Mechanical Projects

• Design-Build: Harold Brothers provides both the engineer and construction team under one contract.

• Design-Assist: You bring your engineer; we assist with budgeting, constructability, and coordination during design.

Yes. While the contractor doesn’t lead the project in Design-Assist, their early involvement can streamline scheduling by resolving issues during design. This often reduces delays during construction caused by redesigns or change orders.

Ideally, you want your mechanical contractor involved during the design phase—not after the drawings are already finalized. By bringing us in early, we can work alongside your architect and engineers to review constructability, suggest cost-saving options, and ensure all systems are properly coordinated before anything is built.

Think of it like involving your designer when planning a kitchen—you don’t want to find out the oven doesn’t fit after the cabinets are installed. Early involvement helps prevent those headaches and keeps your project running smoothly.

In Design-Build, risk is reduced by having one team responsible for both design and construction. This unified approach minimizes gaps, reduces miscommunication, and streamlines accountability, making it easier to resolve issues quickly and keep the project on track.
