Site work for a civil project in Commerce City, Colorado. Completed plans call for site work for a road / highway; and water / sewer project.

As of June 20, 2024, this project is under construction and is expected to be finished by the end of 2024. The South Adams County Water and Sanitation District, acting by and through its South Adams County Water and Sanitation District Activity Enterprise (Owner), is requesting sealed proposals for Construction Manager/General Contractor (CMGC) services for the Districts 2023 Counter Drive Lift Station Improvements. Muller Engineering Company (Muller/Engineer) is providing design services to support this CMGC procurement. Preliminary design has been completed, and Muller will continue to advance this design and submit packages for SACWSD review at intermediate and final design levels and provide design services during construction. The project consists of increasing emergency response time at the District s Counter Drive Lift Station site by creating additional wet well containment capacity. Anticipated work includes construction of a water-tight secant pile wall (or equivalent) containment structure drilled to bedrock adjacent to the lift station s existing wet well, cast-in-place floor and roof slabs, connecting overflow pipe between the existing wet well and new containment structure by HDD or other means, sump pump system to evacuate the containment structure when used, and miscellaneous site restoration, landscaping and surface improvements commensurate with the adjacent properties and neighborhood. The site is in a high-groundwater residential area, in close proximity to the adjacent residences to the north and south, and lies immediately east of a concrete-lined section of the Fulton Ditch. The District currently owns the property to the south of the Lift Station parcel, and will grant an easement and/or relocate the lot line to facilitate construction and create the permanent area necessary for the containment structure. As part of the pre-construction phase services, the selected Contractor will prepare a project risk analysis, and will collaborate with the Owner and Engineer to develop concepts, establish construction methods, and advance the conceptual design included in the Request for Proposals (RFP) to acceptably mitigate the project s risks associated with groundwater control and the protection of nearby structures and residences. The selected Contractor will coordinate with subcontractors, suppliers, and any needed outside consultants in collaboration with the Owner and Engineer to finalize the design, establish a detailed project schedule, and develop a Guaranteed Maximum Price (GMP) for recommendation to the District s Board of Directors. Of critical importance to the success of the project will be the Contractor s role in the management and mitigation of construction, cost, and schedule risks throughout the duration of the project. If the GMP is approved by the District s Board, a GMP Amendment will be executed for the construction phase of the project and establish the Contractor in the role of General Contractor for the completion and final acceptance of the project by the District. Final completion is targeted for early August of 2024, based on anticipated timing of the CDPHE Site Application approval in mid-February. Additionally, interested Contractors are required to attend a mandatory pre-proposal meeting at the project site as set forth in the RFP The District intends to award the contract to the firm which submits the proposal that, in the District's estimation, represents the best value to the District. The District reserves the right to reject any or all proposals, including without limitation, nonconforming, nonresponsive, unbalanced, or conditional proposals. If it appears Owner can perform the Work or secure material for less than the lowest proposal, it may proceed to do so. Owner reserves the right to act in its best interest and may terminate, modify or suspend the process, modify the terms and conditions of this proposal and selection process, and/or waive informalities of any submission.
