BACKGROUND R.L. Alia Company overran the contract time by approximately 100 days and was initially assessed liquidated damages of over $100,000. Subsequently, R.L. Alia fIled a protest and provided additional documentation and details demonstrating that, in a lawsuit, they may be able to show that the plans were not clear enough to allow the bidder to plan for all the intricacies required to install the new water main across the Southcenter Boulevard Bridge through exiSting knockouts and penetrations without significant extra labor, materials, equipment and contract time. Due to the overruns in time, the base contract of $89,615 for construction management (CM) was increased with Amendment 1 by $12,414 and Amendment 2 is pending at $6,771, for a CM total of $108,800. Subsequently, the final settlement Change Order was negotiated in the amount of $73,000 to compensate R.L.Alia Company for all additional direct labor,.equipment and material costs. The attached closeout budget analysis shows that the expenditures exceed the budget amounts by $45,000. . ANALYSIS This final settlement Change Order is a fair and equitable complete compensation. Furthermore, this settlement minimizes the risk of a protracted battle with a contractor and eliminates potential litigation costs. An upcoming agenda item for an interlocal agreement with King County Metro includes savings of up to $110,000 for the City of Tukwila. King County will pay for the design and construction if Tukwila agrees to pay for bidding and construCtion management. See page 81 of the 2008 CIP for proposed savings. RECOMMENDATION Approve using ending water fund balance due to savings in the Interurban Water Reuse project to pay for project budget shortfall.
