Frequently Asked Questions


What is Design-Build for commercial HVAC and plumbing projects?
Design-Build is an integrated project delivery method that combines design and construction services under one contract with Interstate AC. Unlike traditional approaches requiring separate contractors for design and installation, Design-Build streamlines the process by having one team handle both preconstruction and construction phases. We work with both general contractors and owner direct, ensuring your project can be completed with your unique goals in mind.This collaborative approach reduces project timelines by 30-40%, enhances communication between designers and builders, eliminates costly change orders from design-construction conflicts, and provides single-source accountability. For Nashville commercial and industrial buildings, Design-Build delivers customized HVAC and plumbing solutions more efficiently and cost effectively than traditional methods.
What are the advantages of Design-Build for commercial construction projects?
Design-Build offers Nashville businesses faster project completion, reduced costs through streamlined processes, better communication with one point of contact, fewer change orders and disputes, early identification of constructability issues, integrated planning that optimizes system performance, and guaranteed project outcomes. Interstate AC’s Design-Build approach eliminates the adversarial relationships common in traditional design-bid-build projects, where designers and contractors work separately. Our team coordinates all aspects from initial concept through final commissioning, ensuring HVAC and plumbing systems meet specifications, budgets, and timelines while delivering long term performance and efficiency.
