Modjeski and Masters has been involved in all major areas of project delivery for bridge engineering projects. Our staff have an in-depth understanding of the unique requirements of each delivery model:
- Design-Bid-Build (DBB): An owner develops contract documents with an architect or an engineer consisting of a set of blueprints and a detailed specification. Bids are solicited from contractors based on these documents; a contract is then awarded to the lowest responsive and responsible bidder.
- Design-Build (DB): An owner develops a conceptual plan for a project, then solicits bids from joint ventures of architects and/or engineer and builders for the design and construction of the project.
- Construction Manager/General Contractor (CM/GC): An owner will hire a contractor to act as a combined agent and general contractor. As substantial portions of the documents are completed, the GC/CM or CM/GC will solicit bids from suitable subcontractors. These may be bid openly (similar to DBB) or via an alternative subcontractor selection process. Subcontractors and sub-CCM's are frequently contracted to the GC/CM or CM/GC but may be contracted directly to the owner. This may allow for accelerated construction and confirmation of pricing, sharing of risk between owner and contractor, and flexibility in construction investigation, sequencing, and procurement.
- Public-private partnership (P3): A public–private partnership is a cooperative arrangement between one or more public entities (typically the owner) and another (typically private sector) entity to design, build, finance, and at times operate and maintain, the project for a specified period of time on behalf of the owner.
