Dear Sir:
On September 2, 2021, the Board of Commissioners authorized the Director of Procurement and Materials Management to advertise Contract 16-127-3D A/B and C/D Service Tunnel Rehabilitation - Phase Three, Stickney Water Reclamation Plant at an estimated cost between $16,625,000.00 and $20,125,000.00.
The bid opening was November 2, 2021. The sole bid was rejected on December 16, 2021.
During the original bidding process, questions were raised that required clarifications and additional work required under the contract documents. Prior to the re-bid, the District worked with the engineering consultant to revise the contract drawings and specifications to address these issues and to clarify the details of the work. It is anticipated that these revisions to the documents and drawings should attract more bidders. The cost estimate for the project has been revised to reflect the additional work and to reflect these inflationary increases.
The purpose of this project is to perform localized repairs of deteriorated segments of various service tunnel structures within the Stickney Water Reclamation Plant. Some of these structures are over 80 years old and contain utilities vital to plant operations. This project is required to restore the structural integrity of deteriorated concrete slabs, walls, beams and columns, and restore them in such a way to prevent further accelerating deterioration.
The project consists of the following:
1. Structurally rehabilitate approximately 1050 lineal feet of the A/B Service Tunnel, 1050 lineal feet of the C/D Service Tunnel, 733 lineal feet of the South R&D Tunnel, 225 lineal feet of the E-W Aerated Grit Tunnel and provide minor repairs on other tunnels.
2. Provide temporary and/or permanent relocation of electrical, mechanical and process utilities inside the tunnels. Remove abandoned electrical conduits and mechanical piping from the tunnels.
3. Install new or repair pipe racks, piping, electrical conduits, lighting, and mechanical equipment in the A/B and C/D Service Tunnels and the South R&D Tunnel.
4. Modify and upgrade the A/B and C/D Service Tunnel ventilation systems, including electrical feeds, fans, ductwork and associated appurtenances. Provide additional temperature control by repairing and insulating Batteries A, B, C and D Air Mains.
It is estimated that 120 jobs will be created or saved as a result of award of this contract with an estimated 152,368 man-hours of skilled trades utilized.
The estimated cost for this contract is between $23,845,000.00 and $28,865,000.00. The cost range will be stated in the advertisement for bids.
