CMAR vs Design-Bid-Build: The Great Debate

Two Worlds Collide
In the red corner, we have the tried-and-true Design-Bid-Build (DBB) method. In the blue corner the up-and-coming contender, Construction Management at Risk (CMAR). But how do these two heavyweights of the construction world differ? Grab some popcorn because we’re about to dive into the main distinctions between CM at Risk projects and traditional Design-Bid-Build.
The Key Differences Between CM at Risk and DBB
The Timeline Tango
First on our list of disparities is the project timeline. In a traditional DBB approach, the design phase comes first, followed by bidding, and finally, construction. It’s a linear process that can sometimes feel like a slow dance. With CM at Risk, however, the design and construction phases can overlap, allowing for a little “fast-tracking” action that can save both time and money. It’s like trading your two-step for a lively salsa.
Collaboration vs Competition
When it comes to working relationships, CMAR and DBB are like night and day. In a DBB project, contractors submit competitive bids after the design is complete, which can sometimes create an adversarial atmosphere. CMAR, on the other hand, fosters a collaborative environment by involving the construction manager early in the design process, working closely with the owner and architect. It’s like hosting a construction tea party to which everyone’s invited.
Exploring More Contrasts Between CM at Risk and DBB
The Price is (Not) Right
One of the most significant differences between CMAR and DBB lies in the financial realm. In DBB projects, the owner typically selects the lowest bidder, which can sometimes lead to cost overruns if the contractor underestimates the project’s complexity. CMAR projects employ a Guaranteed Maximum Price (GMP), putting the risk of cost overruns on the construction manager and giving the owner some financial peace of mind.
Quality Matters
Quality is king in construction, and the way each method approaches quality control is another point of distinction. In DBB projects, the contractor is responsible for the construction quality, while the architect and owner play a more hands-off role. In CM at Risk projects, the construction manager is actively involved in the design process and can provide valuable input on constructability, materials, and systems, helping to ensure top-notch quality throughout the project.
And the Winner Is…
Finding the Right Fit
So, which method is better: CMAR or DBB? The truth is, it depends on the project. Each approach has its pros and cons, and the best choice will depend on factors such as project complexity, owner involvement, and the desired level of collaboration. The key is to assess your project’s unique needs and determine which method aligns best with your goals and expectations.
In Conclusion
CMAR and DBB are two distinct construction delivery methods, each with its own set of advantages and disadvantages. Understanding the differences between them can help you make an informed decision and set your project on the path to success. Whether you opt for the collaboration-focused CMAR or the traditional DBB, remember that the most important thing is to stay true to your project’s vision and enjoy the journey!
