Due to changes in the discharge permit, the City is required to increase the sludge -holding capacity. The most expeditious and economical method to increase sludge -holding capacity and meet the requirement is to concrete line Sludge Lagoon No. 1 and place it back in service, as shown on the attached drawing. Staff proposes to use Western Water Constructors, Inc., to perform the work included in this change order because they are currently under contract for the Phase 3 improvements project. Western Water Constructors has crews and equipment available to begin the work immediately so that the lagoon can be completed and placed in service before the next rain season. Final change order pricing is being negotiated. The Engineer's estimate for the work is $1,032,000. Working together on value engineering ideas, City staff and Western Water Constructors believe the work can be completed for less then $900.000. The contract change order for this work would be approximately 5.5% of the original contract price. The requested appropriation includes contingency funds in case unknown conditions are discovered during the actual installation. The change order costs have been reviewed by City staff and our design engineers, West Yost & Associates. FISCAL IMPACT: This work was anticipated in the cost estimates for the multi -phased White Slough Water Pollution Control Facility Improvements. FUNDING AVAILABLE: The requested appropriation of $900,000 will be from 2007 Certificates of Parti ' i roceeds. vans, Budget Director /17" 11 lqe�JQAA46 J& I F.
