INFORMATIONAL MEMORANDUM

Transportation Committee
FROM: Bob Giberson, Public Works Director
By: Ryan Larson, Senior Program Manager
DATE: July 19, 2013
SUBJECT: Surface Water Lift Station No, 15
Project No, 91041203
Bid Award
ISSUE
Award the bid for construction of the Surface Water Lift Station No. 15 improvements.
BACKGROUND
This project will provide a back-up power generator for the Surface Water Lift Station No. 15, which drains approximately 200
acres of the northern portion of the Tukwila South Development. The station was built in 1977, has four pumps and a total
capacity of 43.7 cfs. The electrical controls and pumps are located below ground and the surface water lift station currently
does not have generator backup power.
ANALYSIS
The Surface Water Lift Station No. 15 project was advertised for bids on July 2 and 9, 2013. Four bids were received and
opened on July 16, 2013. The bids were checked and tabulated and Gary Harper Construction, Inc. is the apparent low bidder
with a bid of $318,568.35. Gary Harper Construction has successfully completed similar project for the City in the past.
A review of the bid tabs showed that the lowest three bidders were within 10% of each other and that the individual bid
amounts were similar. The engineer's estimate was $266,194.50. The engineer's estimate was lower by approximately
$50,000 due to the electrical upgrade component of the project.
This bid award is only for the installation of the backup generator. A second memo will propose the $200,000 purchase for the
actual generator. The total construction budget is $515,000 and with the generator purchase of $200,000, this leaves only
$315,000 for this award. Additional funding is available from the 2013 Small Drainage Program and it is recommended that
$36,000 be transferred to allow for construction of the Surface Water Lift Station No. 15 project.
