Renovation of a water / sewer project in Aurora, Colorado. Completed plans call for the renovation of a water / sewer project.

Reference Number 0000315149 The Work to be performed under the Project consists of furnishing all labor, materials equipment, tools, supplies for expanding the existing UVAOP clean-in-place to the remaining South Train units including UV Reactors 7, 9, 10, 11, and 12. The Work includes primarily mechanical and electrical, instrumentation and control (E, I&C) components. Phase 1 of the project including the installation of a new clean-in-place (CIP) system for UV Reactor No. 8 of the UV South Train, which includes UV Reactors 7 throuh 12. The CIP system mixes a batch of low pH acid solution and recirculates the solution through a single UV reactor over a 12 to 24-hour cleaning cycle to remove chemical buildup. The first phase of the project included constructing the majority of the CIP system including the chemical supply system, batch tank, recirculation pump, and electrical, instrumentation, and controls. The Work to be performed under the Project consists of furnishing all labor, materials equipment, tools, supplies for expanding the existing UVAOP clean-in-place to the remaining South Train units including UV Reactors 7, 9, 10, 11, and 12. The Work includes primarily mechanical and electrical, instrumentation and control (E, I&C) components. The principal project elements generally include the following: • Demolition, including: o Removal of existing softened water piping feeding the UV Reactors and the oxidized water piping exiting the UV Reactors and pipe supports • Mechanical, including: o Installation of new epoxy-lined softened and oxidized water piping and pipe supports o Installation of new small diameter PVC piping connecting the cleaning system to UV Reactors 7, 9, 10, 11, and 12 o Installation of new acid solution supply and return control valves o Miscellaneous existing chemical solution panel and other minor “lessons learned” improvements • Electrical, instrumentation and control, and security to include: o Electrical and control wiring for new control valve actuators o New discrete input/output (DI/DO) module terminal blocks and DI/DO modules o Jacobs Engineering will perform the programming (Jacobs performed programming during the first phase of the project) and the contractor will be responsible for integration. Work will be performed by an Integrator acceptable to Owner who is a subcontractor to the General Contractor performing the construction. Question Acceptance Deadline 04/11/2023 04:00 PM EDT
