Feasibility & Development

During the Feasibility and Development Stage, the City uses various methods to inspect and analyze its system. Physical inspection is performed using cameras and other technologies. Data analysis is completed using engineering tools and processes. Master plans, hydraulic modeling, planning, assessments, and detailed engineering studies are often completed during this Stage. Based on an in-depth understanding of the system, the City can identify which areas are most in need of improvement. This allows projects to be prioritized, selected, and planned for capital expenditures. Design alternatives and concepts are often defined and selected during this Stage. This phase can take several months to several years depending on the complexity of the assessment.

After projects have been selected, engineering consultants are typically selected to develop designs for the projects. Securing engineering services, which includes defining the detailed scope of work, negotiating cost, preparing the required forms, contract and legal review, and City approval, typically takes between four and eight months.

Design

During the Design Stage, the engineer (either City staff or a contractor) prepares detailed plans and specifications for the project. Any needed servitude (easement) plats and permit applications are also prepared by the engineer. Completing detailed design documents for a typical project usually takes between 9 and 18 months. A complex design, permit approvals, or land (servitude/easement) acquisitions can extend the time required to complete this Stage.

Bid & Award

During the Bid and Award Stage, the City solicits proposals from bidders to complete construction of the project. Bids are advertised, received, and evaluated. Contracts are then executed with the selected bidder. This process typically takes 3 to 6 months to complete. 

Construction

Construction is when elements of the project are physically completed. The selected contractor is responsible for completing the project in accordance with the contract documents. The City and its consultants oversee, inspect, and document the contractor’s activities. Equipment installed during the project is commissioned to validate it is operating properly. Construction typically takes 6 months to 30 months to complete depending on the size and complexity of the project.

Post-Construction

During the Post-Construction Stage, the City operates and maintains the system. The City may also perform inspections of completed work during the correction period (warranty). Maintenance includes routine inspections, cleaning, and emergency repairs and replacements.
