Body
Dear Sir:
Authorization is requested to increase the cost estimate for Project 07-168-3P Scum Concentration, Centrifuge Building, Preliminary & Imhoff Tanks, Elevator Improvements, Diffuser Plates and Trailer Replacement, Stickney Service Area, LASMA, in the amount of $29,700,000.00 from an amount $2,000,000.00 to an amount not to exceed $31,700,000.00.
The authority to add this project was obtained at the Board Meeting of January 17, 2008.
The project was initiated to accomplish several infrastructure rehabilitation items within the Stickney Service Area. Since the inception of the project, the Maintenance and Operations Department has identified further needs. Since there are no other major projects pending in the service area, it was deemed most efficient to add these items to this project. Additionally, since bids for Project 06-157-3P were rejected, the scope of work from this project was incorporated into Project 07-168-3P.
The increase is due to added scope of work at the Stickney Water Reclamation Plant, which consists of: nondestructive inspection of digester feed and recirculation piping; replacement of diffuser plates, drop piping, and air main couplings and spool pieces in the Y-walls in Aeration Battery C; replacement of diffuser plates, coarse bubble diffusers, drop piping, and air main couplings and spool pieces in the Y-walls in Aeration Battery; replacement of sludge piping in Imhoff Batteries B and C; and replacement of the existing glass entrance doors and concrete paved area at the cafeteria entrance. The added scope of work at LASMA consists of removing an existing 31’ x 15’ construction trailer with utilities and all other appurtenances; removing the existing construction office with utilities and all other appurtenances; and providing a new 21’ 9” x 60’ permanent construction trailer with utilities and all other appurtenances.
Therefore, it is recommended that authority be granted by the Board of Commissioners to increase the cost estimate for Project 07-168-3P in the amount of $29,700,000.00 from an amount of $2,000,000.00 to an amount not to exceed $31,700,000.00.
Funds for the revised cost estimate are available in Accounts 401-50000-645750 and 645780.
