Title
Resolution Approving a Design Consultant Agreement with Burns & McDonnell Engineering Company, Inc. [Plum Creek Water Purification Facility Expansion Project, 1929 Liggett Rd., Castle Rock, CO 80109]
Body

Executive Summary
Castle Rock Water (CRW) staff requests approval of a Resolution (see Attachment A) approving a Services Agreement (see Exhibit 1) with Burns & McDonnell Engineering Company (BMcD) to complete design phase engineering services for the Plum Creek Water Purification Facility (PCWPF) Expansion project at a contract amount of $2,388,880. A competitive process was used to obtain proposals from qualified consulting firms, and BMcD’s proposal met the qualitative requirements. This project is a key component to Castle Rock’s long term renewable water plan and will expand the PCWPF treatment capacity from 6 million gallons per day (MGD) to 12 MGD. Facility improvements include but are not limited to expanding water treatment and solids handling systems, increasing high service pumping, and installing an emergency electrical generator.
Five consulting firms were invited to submit proposals in response to the Request for Proposals (RFP) issued on February 6, 2023. The design services require full time commitment of the firm’s core project team to complete these services within the project schedule. Four of the firms decided not to submit proposals and either did not have the available resources to commit to this project or have not been competitive on past CRW PCWPF projects. For context, BMcD has completed the engineering for the original plant and the advanced treatment components of the plant.
BMcD is a nationally recognized engineering firm with offices located in Douglas County. They have recent experience completing projects using similar treatment technologies and project delivery methods that are planned for the PCWPF Expansion Project. This project will employ a Guaranteed Maximum Price Construction Management (GMPCM) delivery method to complete the project. Prior experience with similar projects and alternate project delivery methods is a critical criterion in the consultant selection process, and BMcD has the requisite experience.
Staff recommends approval of the services agreement for $2,388,880, plus a Town-managed contingency of $119,444 (5%), for a total project authorization of $2,508,324. Completion of the design portion of this project is expected by Summer of 2024. Construction Work Package 1 is early procurement of long lead equipment packages and award of this package is expected in January 2024. Construction Work Package 2 is scheduled for completion in 2026. The total project budget with estimated costs for construction work items is shown in the table below. The total funding currently projected in the five-year capital plan is $60,000,000. A future budget amendment will be completed to fund any difference between current planning budget and construction cost estimates developed with contractor input and detailed project designs.
