Gravitv Sewer Proiect Project No. 90440208, Contract No. 11 -099 Project Completion and Acceptance ISSUE Accept contract as complete and authorize release of retainage. BACKGROUND The Notice to Proceed for Contract No. 11 -099 with R.L. Alia Construction of Renton, Washington, was issued on August 19, 2011 for construction of the Interurban Avenue S. Gravity Sewer Project. This project was designed to replace a failing sewer lift station with a series of gravity feed lines on the west side of Interurban Avenue S. between Fort Dent Way and S 144 Street. DISCUSSION Construction was physically completed on May 10, 2012. Ten change orders were issued during construction for a total of $28,580.38. The change orders can generally be summarized as minor revisions that were offset by under -runs in quantities for various bid items. The largest change order in the group ($13,146) was due to an unexpected subgrade condition which caused problems with the trench when installing the new sewer main. The total budget for this contract, with an 11 contingency, was $828,256.25. A retainage bond was used, so no retainage amount was withheld. Contract Award Amount 681,440.00 Change Order Nos. 1 10 28,580.38 Cost Under -runs (103,260.91) Sales Tax 57.642.15 Total Amount 664.401.62 RECOMMENDATION The Council is being asked for formal acceptance and retainage bond release authorization, subject to standard claim and lien release procedures, for the contract with R.L. Alia Construction, in the amount of $664,401.62 and to consider this item on the Consent Agenda at the June 4, 2012 Regular Council Meeting.

BACKGROUND The Departments of Health and Ecology require the City of Tukwila to update the Water and Sewer Comprehensive Plans every six years. In 2010, the City contracted with Carollo Engineers to update the Water and Sewer Comprehensive Plans. DISCUSSION Carollo Engineers completed the work draft of Chapter Two, "Demographic Analysis and Demand Projections," for the Comprehensive Plan in October 2010 using current population data. In November 2010, DCD requested that the Public Works department rerun the population study model with 4,800 new housing units and 15,500 net new jobs by the year 2031. In the 2005 water model, most areas of the City had more than adequate fire flows in excess of 4,500 gpm. In May 2011, the Tukwila Fire Marshal requested that the fire flows in the Commercial Business District (CBD) be increased from 6,000 gpm to 8,000 gpm. The increased fire flows resulted in most of the CBD not having adequate fire flows and would require costly upgrades to existing water lines. In April 2012, the Fire Marshal revised the required fire flows in all areas of the CBD except north of Strander Blvd to 6,000 gpm. The Consultants scope of work was to prepare a sewer system map book for the Public Works field crews to carry in their vehicles. The task went over budget due to City staff finding multiple discrepancies in the existing sewer pipe maps. FINANCIAL IMPACT Supplement No. 2 will increase the Consultant's scope of work for Task 300 Planning Considerations for $5,721.50, Task 700 Distribution System Analysis and Task 900 Capital Improvement Program for $10,000, and Task 060 Hydraulic Model and Mapping for $6,000, for a total Supplement of $21,721.50. Funding for the additional work will come from the Interurban Water Reuse Project, page 86, 2012 CIP.
