BID AWARD
ISSUE
Award the bid for the Southcenter Boulevard Water Main Replacement project (see attached map for
project location).
BACKGROUND
After the 2001 earthquake, the existing 12-inch cast iron water main in the Green River Trail broke.
The main was repaired and it was determined that the existing line needed to be upgraded to ductile
iron pipe. The water main is being installed in the WSDOT limited access area of 1-405 and WSDOT
requires work to be done at night in this area. The water main is also being attached under the bridge
crossing the Green River. These two factors have resulted in increased construction costs.
The contract documents for the project were completed in the fall of 2006 and the project was
advertised on December 7 and 14, 2006. The project is listed in the proposed 2007 CIP, page 78.
Four bids were opened on January 5,2007. The engineer's estimate was $720,123.48. R. L. Alia
Company of Renton, Washington, submitted the low bid of $764,864.00 for the base bid. All bids
included state sales tax.
The City of Tukwila currently has R. L. Alia under contract for the AllentownIFoster Point Water and
Sewer Improvements project and work on the project is satisfactory.
BUDGET AND BID SUMMARY
When the 2007 budget process was completed in September of 2006, the project budget was $490,000.
City staff requested an additional $130,000 in November of 2006 due to the steep rise in construction
costs in the late fall. The funds could not be shifted because the preliminary budget was completed. It
was decided to bid the project using funds from other 2007 projects. The remaining $400,000 to
complete the project will be from the Interurban Ave South Waterline project. The Interurban Ave
South Waterline project will be moved to 2008 with the design completed this year.
