Tolt Treatment Facility
Innovative Construction & Operation
The Tolt Treatment Facility was designed and built, and is operated under an innovative Design-Build-Operate (DBO) process. This non-traditional approach means that proposers compete for a contract that includes design, construction, and long term facility operation, and the owner makes a contract with a single entity for the implementation of the project.
The DBO contract for the Tolt project is primarily performance-based, which allowed the project to be done in the most efficient and practical manner. It encouraged cooperation among site permitting specialists, designers, constructors, and operators, and allowed project proposal teams to push the design envelope and be innovative in project implementation.
In addition, the contract is explicit about the water quality, supply, maintenance and engineering standards that must be incorporated into the facility.
A single point of accountability was established with the contractor rather than segmenting responsibility and liability. This consolidated accountability drove the contracted team to coordinate design, construction, and operations phases to achieve better quality, a faster schedule, and lower cost. The Tolt Treatment Facility was completed with an estimated $70 million in savings over the traditional method of designing, bidding, building and operating such a project.
