Project Delivery - Design-Bid-Build

The Design-Bid-Build (DBB) method of project delivery is easily the most familiar to owners, architects and contractors.

D. Brown Management Profile Picture

No contractor should ever lose their ability to compete, win, and build profitable projects using this method of delivery. It keeps your estimating and operations teams sharp.

CM at Risk: Project Delivery Methods - Definition of Design-Bid-Build and pros and cons.

In this method, the project owner contracts separately with the architect for design and a single prime contractor for construction.  

  • It is the primary procurement method used for public works projects.
  • Due to the sequential design followed by the construction workflow, it has the longest timeline.

  • Contractors are typically forced into a competitive bidding situation, resulting in a low initial construction cost.

  • Because the contractors were not involved in the design phase, there are frequently cost and schedule overruns that sometimes end in litigation.  

The negatives must be weighed against the positives for this project delivery method. In many cases this is absolutely the right method for the project.

Coachability and Capability Matrix
Sustainable growth over time in your career and as a company has to do with being coachable and capable. Optimum growth occurs when we are stretching ourselves and others just beyond our current capabilities and then developing the needed capabilities.
Using a Vision to Create Desire and Context for Tasks
There is a whole lot of work involved in building projects and building a construction company. It is easy to get mired down in endless to-do lists, processes, and problems. The thing that holds this all together and accelerates performance is the vision.
Coaching and "GPS Feedback"
Contracting is a business where operational excellence is a major factor in winning. Project success which we all know is very different than “winning” the project depends on thousands of details over many months executed well.
