There is too much waste in construction: waiting, excess motion of materials, defects, overdesign, and the list goes on. It is difficult to fully remove waste from the process because every project is unique, often involves working with a new project team and new stakeholders to meet new objectives. And it doesn’t help that on most projects the contractor is engaged only after the design has been fully completed.
A project delivery method defines the roles, responsibilities, and timing of the engagement of project stakeholders working to design and build a facility. The traditional design–bid–build (DBB) delivery method offers limited opportunities for collaboration between project stakeholders because the contractor cannot inform the design.
