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 a 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$206,619 purchase for the
actual generator.The total construction budget is$515,000 and with the generator purchase of$206,619,this leaves only
$315,000 for this award.Additional funding is available from the 2013 Small Drainage Program and it is recommended that
$43,000 be transferred to allow for construction of the Surface Water Lift Station No. 15 project.

II. BUSINESS AGENDA
A. Surface Water Lift Station No. 15 —Bid Award
Staff is seeking Council approval to award a bid to Gary Harper Construction, Inc. in the amount of
$318,568.35, for the construction of the Surface Water Lift Station No. 15 project. This project will
provide a backup generator for this station, which drains approximately 200 acres of the northern
portion of the Tukwila South Development. Gary Harper Construction is the low bidder and has
successfully completed a similar project for the City. $36,000 unused dollars will be transferred
from the 2013 Small Drainage Program to cover a project budget shortage. UNANIMOUS
APPROVAL. FORWARD TO AUGUST 5 REGULAR CONSENT AGENDA.
B. Surface Water Lift Station No. 15 —Purchase of Backup Generator
Staff is seeking Council approval of the purchase of a 600KW generator in the amount of
$206,619.93 from Cummins Northwest, LLC for the Surface Water Lift Station No. 15 project
described in item A above. Cummins is the manufacturer of the majority of the City's standby
generators and maintenance staff are satisfied with the reliability and serviceability of the units.
UNANIMOUS APPROVAL.FORWARD TO AUGUST 5 REGULAR CONSENT AGENDA.
C. 42nd Ave S/Allentown Roadside Barrier Warrant Analysis
Staff presented and discussed the draft roadside barrier warrant analysis for 42nd Avenue South in
Allentown that was prepared by KPG, Inc. Several areas of the river bank along 42nd Avenue
South and South 115`h Street are being recommended for guardrail or barrier installation and/or
upgrades and modifications. Most of the areas analyzed in the report would benefit from beam
guardrail type 31. Existing concrete barriers are recommended to be removed and replaced due to
being unrestrained, their proximity to the edge of pavement, and erosion under the base. The total
project cost estimate for all recommendations is $366,480. The report also included short-term
safety improvement recommendations, which are not figured into the total cost. Committee
members asked clarifying questions about definitions and barrier types.
The committee packet includes a draft CIP sheet that reflects staffs proposal to spread the cost and
the construction over the next six years to minimize the impact to the Residential Street Fund (103
Fund). Committee members requested that staff prepare a proposal that would reflect a
compressed schedule allowing construction to be completed sooner but having more immediate
financial impact.
