Design-Build Projects: Understanding the Cash Flow Risks for Subcontractors

Design-build has emerged as America's fastest-growing construction delivery method, projected to represent over 47% of construction spending by 2026 - approximately $1.9 trillion nationwide, according to the Design-Build Institute of America (DBIA). While this collaborative approach offers many benefits for project owners, it can create unique financial challenges for subcontractors.

What Makes Design-Build Different? 

Unlike traditional delivery methods where design and construction have separate contracts, design-build combines both under a single contract. This integrated approach emphasizes collaboration, teamwork, and creative problem-solving. While this can lead to faster project delivery and fewer claims overall, it often leaves subcontractors managing significant financial risks.

How Design Changes Impact Subcontractor Cash Flow? 

Consider this typical scenario: A mechanical contractor bids based on preliminary drawings. As architectural designs progress, major equipment locations shift and ductwork needs rerouting. This creates a cascade of financial challenges:

• Work continues while change orders remain unapproved
• Subcontractors finance design changes with their own capital
• Payment delays stretch 45-90 days while funding labor and materials
• Material prices rise between initial bid and actual installation

Why Are Financial Risks Higher in Design-Build? 

While design-build promises benefits like faster delivery and fewer claims, subcontractors often bear increased financial pressure. The combination of incomplete designs and payment delays creates particular strain for specialty trades who carry substantial material and labor costs. Even as the project team collaborates to solve design challenges, subcontractors must often fund significant changes while awaiting approval and payment.

How Can Subcontractors Protect Their Cash Flow? 

Success in design-build projects requires a multi-layered approach to financial protection:

1. Maintain rigorous documentation of all design versions, verbal directions, and completed work
2. Include contract clauses that specifically address design evolution and price escalations
3. Secure flexible financing options that provide quick access to funds when change orders and payment delays create cash flow gaps

As design-build continues its rapid growth across both private and public sectors, subcontractors need robust financial strategies to succeed. Solutions like Constrafor's Early Pay Program help stabilize finances by providing quick access to funds without adding debt, allowing contractors to focus on execution rather than financing.
