What Project Delivery Methods Are (and Why They Matter)
Welcome
Hello, and welcome. This is Super Structures General Contractors — a national general contractor headquartered in Powhatan, Virginia — here to help you and your clients build something that lasts. We're glad you're with us, and we look forward to connecting with you.
Today we're tackling What Project Delivery Methods Are (and Why They Matter), and it's worth your full attention. Here's the big idea to walk away with: The delivery method sets who holds the contracts, when the builder joins, and how price is fixed — driving cost, speed, quality, and risk; the main families are Design-Bid-Build, Design-Build, and CM at-Risk, with the industry trending toward collaboration. Get this down and you'll work smarter, safer, and a step ahead of the crew.
A project delivery method defines how the owner contracts for design and construction — who holds which contracts, who carries which risks, and when the builder gets involved. It's one of the most consequential decisions on any project, shaping cost certainty, speed, quality, and risk.
The variables that define every method
- How many contracts the owner holds (and with whom).
- When the builder joins — after design is complete, or during it.
- How the price is set — lump sum, guaranteed maximum price (GMP), or cost-plus.
Going Deeper (Intermediate)
The three core methods are Design-Bid-Build (DBB), Design-Build (DB), and CM at-Risk (CMAR), with variations like CM Agency, multi-prime, and Integrated Project Delivery (IPD). Each trades off cost, schedule, quality, and risk differently, and each puts the owner in a different relationship with the designer and builder. The long-running trend is away from pure low-bid DBB toward more collaborative methods as projects grow complex.
Advanced / Pro-Level
The delivery method interacts with two other choices: procurement (low-bid vs. best-value/qualifications) and contract type (lump sum / GMP / cost-plus). It also drives risk allocation — for example, the Spearin doctrine (in DBB the owner impliedly warrants the design it provides). Public owners historically favored DBB for transparency, but most are now allowed alternative delivery for complex or fast projects. As a contractor, you position differently for each — sharp bidding for DBB, teaming with designers for DB, preconstruction/relationship selling for CMAR.
Practice Challenge
An owner wants the fastest schedule and a single point of responsibility for both design and construction. Which family fits, and what do they give up? (Answer: Design-Build — one entity owns design + construction, enabling overlap/fast-track and single-point accountability; the owner gives up some control over design details and the price transparency of competitive bidding.)
Takeaway: The delivery method sets who holds the contracts, when the builder joins, and how price is fixed — driving cost, speed, quality, and risk; the main families are Design-Bid-Build, Design-Build, and CM at-Risk, with the industry trending toward collaboration.
