BACKGROUND This project will provide roadway improvements on Tukwila International Boulevard from S 116 St to S 138 St. The improvements will include curbs, gutters, sidewalks, landscaping, retaining walls, traffic signal modifications, storm drainage facilities, paving, and other related street amenities. The project will also include sanitary sewer and water utility work that will be reimbursed by the respective districts. The project was advertised for bids on October 9 and 16 and bids were opened November 13, 2008. The bid proposal included a base bid and one additive alternate for concrete wall facings. Ten bids were received with the low base bid of $11,461,309.20 from Gary Merlin Construction Company. The engineer's estimate was $14,974,001.00 in the attached bid tabulation. ANALYSIS The bids were reviewed and tabulated. No errors or irregularities were discovered in the five lowest bids. Two mathematical errors were discovered in the remaining bids that did not affect the bidding order. The sales tax rate was shown incorrectly on the Proposal as 8.8% and was corrected in the bid tabulation (for all bids and the engineer's estimate) to reflect the current rate of 9.0 A new rate of 9.5% will be instituted in January 2009 that will increase construction costs by approximately $330.00. Staff has reviewed the lowest bid, completed reference checks, and determined the Contractor to be responsive and responsible. Gary Merlino Construction has been given good recommendations from other agencies and has performed satisfactorily on previous construction projects for the City. Since the bids received for the project were very favorable, it is possible to award the base bid, award the additive alternate, retain a 15% construction contingency and still remain within the project budget. Award of the work included for the Valley View Sewer District and Water District 125 is subject to approval by each District's Board. District staff recommendations have instructed us to award their portions of the project at $19,096.80 (sewer) and $52,712.40 (water).

ADDITIVE ALTERNATE BID ITEM: SHOTCRETE FASCIA PANELS The shotcrete fascia panels included in the bid proposal as an additive alternate bid item are necessary components of the soldier pile wall structures. Without the fascia panels, the H -pile with timber lagging walls are considered "temporary" structures. Over time, the wood will decompose; lose its structural capacity and fail. The proposed concrete fascia panels will cover the timber lagging, thus making the finished wall a permanent structure. The fascia panels will also include an anti graffiti coating and will be more visually pleasing than the soldier pile wall. The objective of bidding the shotcrete fascia panels as an additive alternate bid item was to make the project more affordable if construction bids came in too high, as was expected throughout the design phase. The walls could be constructed without the shotcrete fascia, but the fascia would need to be added within 5 to 10 years based on engineering recommendations. The bidding and construction climate has changed dramatically in the past six months. Favorable bids were received on November 13, 2008 with the lowest bid (including the additive alternate bid item) well within the budget and engineer's estimate. The additive alternate shotcrete fascia panels cost $800,000 and the engineer's estimate was $1,358,491. It is recommended that the additive alternate bid item be constructed now rather than in a future contract at a much higher cost to the City. The additive alternate bid item includes approximately 42,000 square feet of shotcrete fascia panels covering walls 1 through 4 on the east side of Tukwila International Boulevard.

BUSINESS AGENDA A. Tukwila International Boulevard Phases II and III Staff is seeking full Council approval to award a bid to Gary Merlin Construction Company m the amount of $12,261,309.20 for construction of Tukwila International Boulevard (TIB) Phase II and III improvements. Robin Tischmak provided a brief overview of the project explaining that these phases will provide roadway improvements on TIB from South 116 Street to South 138 Street. Robin also explained the additive alternate that will now be included in the project due to the bids coming in under the engineer's estimate. The $800,000 additive alternate is a concrete wall fascia that will run on both sides of the highway. The /'alternate should not be considered an optional addition only to improve the physical attributes of the project; the additive is an integral part of the project which was considered as an additive in order to save money based on predictions of an escalating bid climate. Committee members asked staff to include a sample of what the fascia will look like in the packet which goes to full Council. UNANIMOUS APPROVAL. FORWARD TO DECEMBER 8 COW FOR DISCUSSION. Mike Hansen, a representative from Sabey Corporation, expressed his company's desire for undergroundmg wires, specifically in the Homeland Security and Intergate West building locations. Mr. Hansen offered his assistance in encouraging a conversation between the City of Tukwila and Seattle City Light regarding the possibility of pursuing an undergrounding opportunity. Mayor Haggerton briefly explained the undergrounding history and issues the City has been faced with regarding the anticipated high cost of undergrounding. He believes that a facilitated discussion between the City of Tukwila, Seattle City Light and Sabey Corporation will encourage the pursuit of possible undergrounding opportunities. Mayor Haggerton has consistently stated in the past, and currently believes, that undergrounding is in the best interest of the City. Staff stated that Transportation Improvement Board funds will not pay for undergrounding; however, undergrounding was part of the original Improvement Board grant application.
