RFP Engineering - Phase I of the North Complex Hazeltine Pump Station and Complex EI and C Project

Site work and new construction of a water / sewer project in Denver, Colorado. Conceptual plans call for the construction of a water / sewer project. Denver Water is seeking a Consultant to provide Structural and Architectural pre-design and 30% design services for Phase I of the North Complex Hazeltine Pump Station and Complex EI&C Project including assisting with the Basis of Design Report, evaluating existing Geotechnical Data and performing an additional Geotechnical Investigation, if needed, developing wet well design and building alternatives, performing cost estimates, and delivering 30% Structural and 30% Architectural Designs. The Hazeltine Pump Station will be in the northeast corner of Hazeltine Reservoir and will pump water out of the reservoir into the existing concrete outlet structure in the same area that connects to a box culvert crossing under 120th Parkway to the South Platte River. It will also pump water out of Hazeltine Reservoir into the existing tee on the North Fulton Pipeline to fill Dunes and Tanabe Reservoirs above their maximum gravity fill elevations. The Hazeltine Pump Station is currently envisioned to consist of the following components: - Concrete intake structure on reservoir floor with steel trash rack. - Reinforced concrete pipe intake pipeline. - Approximately 65-foot-deep by 60-foot-wide by 40-foot-long concrete wet well to house 4 to 6 vertical turbine pumps (220 cubic feet per second of cumulative pumping capacity) - Enclosed pump gallery above the wet well. - 60-inch steel discharge header pipe that connects to both the existing complex outlet structure and the existing 42-inch tee in the Hazeltine bypass pipeline. - Enclosed at grade electrical room adjacent to pump gallery to house motor controllers, variable frequency drives (if needed), control panels, and other miscellaneous pump station electrical components. Electrical transformers will be exposed on a slab adjacent to the enclosed electrical room. - Basic building structural system and roofing system to enclose the pump gallery and electrical room. - H2S monitoring and mitigation system for wet well, pump station and electrical room. - Raw water washdown system, floor drains, and building heating, ventilating, and air conditioning (HVAC). The North Complex Hazeltine Pump Station and Complex EI&C Project will be completed in three construction phases: Phase I: Hazeltine Heavy Civil (Focus of this RFP) Hazeltine Pump Station intake structure, intake pipeline, wet well and enclosed pump station, enclosed electrical room, large diameter yard piping, earthwork, site grading, and landscaping. Anticipated schedule: - Design: August 2022 to September 2023 - Bidding and award: October to December of 2023 - Material procurement and construction: January to August 2024 Phase II: North Complex EI&C Complex wide power distribution, supervisory control and data acquisition (SCADA), lightning protection, interior and exterior pump station and area lighting, security systems, unit heaters and ventilation for all structures, electric actuators for existing valves, electrically operated vehicle access gates, reservoir level measurement systems, and water quality measurement systems. Anticipated schedule: Design: July 2022 to September 2023 Bidding and award: October to December 2023 Material procurement, construction, and commissioning: January 2024 to April 2026 Phase III: Pump Station Mechanical and Electrical Scope: Vertical turbine pumps and motors, station piping and valves, overhead crane, building HVAC, station transformers, motor control centers, variable frequency drives, power, and lighting instrumentation and controls (I&C). Design: October 2023 to July 2024 Bidding and award: August to September 2024 Material procurement, construction, and commissioning: October 2024 to March 2026 The anticipated Project Schedule for Phase I: Hazeltine Heavy Civil is summarized as follows: May 6, 2022 - Request for Proposals issued to Contractors May 19, 2022 - Mandatory Pre-Proposal Meeting May 24, 2022 - Final Written Questions Due June 2, 2022 - Proposals Due June 21, 2022 - Contractor Interviews (if required) July 13, 2022 - Selected Contractor Recommendation to the Board July 28, 2022 - Notice to Proceed Issued to Selected Contractor Oct 6, 2022 - Final Basis of Design Report Completion Oct 27, 2022 - 30% Project Design Completion Feb 2, 2023 - 60% Project Design Completion May 11, 2023 - 90% Project Design Completion Sept 14, 2023 - Final for Bid Document Completion July 18, 2024 - Construction Complete The method of contractor selection has not been determined at this time
