SUBJECT: Surface Water Lift Station No. 15
Project No. 91041203
Project Status
ISSUE
Provide a project update and anticipated construction schedule for the Surface Water Lift Station No.
15 Improvement Project.
BACKGROUND
A design contract was issued to PACE Engineering in March 2011 to design 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, a
total capacity of 43.7 cfs and is the largest storm water lift station in the City. The electrical controls and
pumps are located below ground and the station currently does not have generator backup power.
Construction was originally planned for 2013, but staff was unable to secure the needed easements.
Universal Field Services was hired in May 2012 to negotiate with the out of state property owner for the
required construction and permanent easements needed for the project.
STATUS
The property owner recently approved the required easements and returned them to the City for
payment and execution. The total cost for the easements is $43,899, which includes temporary and
permanent easements and an administrative settlement of $10,000 to cover attorney's fees. The total
cost for easement acquisition including the real estate negotiator is $56,064, although the project
budget for real estate acquisition is only $40,000. The additional acquisition cost of $16,064 will come
from the Project's construction budget.
The project is currently being advertised with a bid opening scheduled for July 16, 2013. Staff will
request approval to present the bid results and recommend bid award at the July 23 Transportation
Committee meeting. In addition, at the 7/23 Transportation Committee meeting, staff will request
purchase of the backup generator under separate contract. Purchase of the generator requires a long
lead time and is expected to take 3 months. Electrical upgrades to the generator backup for the pump
station must take place during dry periods to avoid the need for temporary bypass pumping systems
and is anticipated to begin in late August.
