Dear Sir:
On February 7, 2019, the Board of Commissioners authorized the Director of Procurement and Materials Management to advertise Contract 15-266-4H, Odor Control Systems at Two TARP Shafts and Decommissioning of the Thornton Transitional Reservoir, Calumet Service Area, at an estimated cost between $4,750,000.00 and $5,750,000.00.
The contract was originally advertised for bid on March 20, 2019. However, no bids were received, which is being reported to the Board of Commissioners under a different item at the meeting of May 16, 2019.
The increase in contract cost estimate is required due to steel tariffs, risk of specialty underground contract work, working under live tunnel conditions, additional work added to the contract, and the expedited schedule required to perform the work.
The purpose of this contract is to complete work required in preparation for the decommissioning of the Thornton Transitional Reservoir (TTR), to complete miscellaneous work related to the operation of the Thornton Composite Reservoir (TCR), and to install odor control systems at the Construction Shaft and Gate Shaft at the Thornton Composite Reservoir.
The work for which tenders are invited consists of furnishing all material, labor and equipment required for the following items:
1. Installation of two concrete plugs within the Thorn Creek Diversion Tunnel to the TTR;
2. Removal of the existing rock plug within the Thorn Creek Connection Tunnel to the TCR;
3. Completion of 254-ft of tunnel lining in the Thorn Creek Connection and Diversion Tunnels;
4. Construction Shaft concrete liner repairs;
5. Decommissioning the TTR Dewatering Valve Chamber;
6. Installation of stone pathways at groundwater monitoring wells and inclinometer instrumentation locations along the west and north rim of the TCR;
7. Installation of reservoir level measurement equipment and rehabilitation of rockfall netting along the north highwall of the TCR; and
8. Installation of 13,500 CFM carbon-filter Odor Control Systems at the Construction Shaft and Gate Shaft.
It is estimated that 51 jobs will be created or saved as result of award of this contract, with an estimated 8,230 man-hours of skilled trades utilized.
The revised estimated cost for this contract is between $8,616,000.00 and $10,430,000.00. The cost range will be stated in the advertisement for bids.
