Title
Authority to advertise Contract 13-246-3M Calumet TARP Screens, Calumet Water Reclamation Plant, estimated cost $9,800,000.00, Account 401-50000-645600, Requisition 1377205
Body
Dear Sir:
Contract documents and specifications have been prepared for Contract 13-246-3M Calumet TARP Screens, Calumet Water Reclamation Plant.
The purpose of this project is to replace the existing, manually cleaned bar screens, which are located upstream of the Tunnel and Reservoir Plan (TARP) pumping station, approximately 350 feet below ground with new screens which will be mechanically cleaned. The cleaning mechanism will be mounted on existing overhead crane rails at ground level and have a gripper which will travel down the shaft and remove the screenings from the bar screens, returning them to the surface for disposal. Even with the addition of the screen cleaning mechanism, there will be a decrease in maintenance costs for the screens due to the elimination of the manual cleaning operation. The installation of the mechanism will provide more frequent cleanings and a safer operation, as workers will no longer need to be lowered into the Wet Shaft via man basket in order to manually clean the screens. This project will restore dependability of equipment to the Calumet TARP pumping station, which is becoming increasingly important as the Thornton Reservoir nears completion.
The project consists of the following:
1. Replacement of the existing bar screens, located 350 feet below ground in the Wet Shaft.
2. Installation of guide channels and supports in the Wet Shaft to guide the gripper the full distance down to engage the bar screen.
3. Installation of the screen cleaning mechanism on existing crane rails in the Wet Shaft Equipment Room at ground level, including the addition of structural members.
4. Installation of associated electrical equipment and controls for the screen cleaning mechanism.
5. Modification of the Wet Shaft grating to provide hinged panels for gripper access to each side of the shaft.
It is estimated that 90 jobs will be created during this construction project.
The estimated cost of this project is $9,800,000.00.
The bid deposit for this contract is $392,000.00.
