PRE-CONSTRUCTION SERVICES

The three most common methods of construction delivery are CM/GC (or CMAR), Design/Build, and Design-Bid-Build.  ECI has experience of successful project delivery utilizing each construction method and has developed a brief informative description for each.   

Under the CM/GC (or CMAR) delivery method, the construction manager (CM) is selected based on qualifications during the design phase of the project.  The CM will assist with cost estimates, scheduling, constructability review and value engineering.  The CM/GC delivery method is a collaborate effort between the owner, designer and contractor.  For more detailed information click here.

Under the Design/Build delivery method, a contractor and designer jointly pursue the project and are selected based on joint qualifications.  The contractor/designer team is responsible for defining roles within the team of who is responsible for all aspects of the project delivery.  For more detailed information click here.

The Design-Bid-Build (DBB construction delivery method is the most common historically.  Under this method, a designer is selected based on qualifications and prepares a full set of construction drawings and specifications.  Once the drawings and specifications are approved by the owner, the project is advertised for bid and a contractor is selected based on minimum price.  Optionally, an owner may incorporate contractor qualifications by pre-qualifying a short list of contractors prior to the bid or requiring a qualifications packet in addition to the bid.  For more detailed information on this delivery method click here.
