TO: Mayor Haggerton
UTILITIES COMMITTEE
FROM: Public Works Director
DATE: February 9, 2011
SUBJECT: Storm Lift Station No. 15 Improvements
Project No. 91041203
Consultant Recommendation and Agreement
ISSUE
Approve a Consultant Agreement with PACE Engineers, Inc. to design pump station improvements.
BACKGROUND
Storm Lift Station No. 15 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 pump
station in the City. The electrical controls and pumps are located below ground and the station does not have
generator backup power.
The Tukwila South Project will construct the north storm pond with a total capacity of approximately 15 acre -feet of
storage. This pond will then be connected to Storm Lift Station No. 15 through a 36" storm pipe. Development of
the Tukwila South Project will significantly increase the discharge to this station.
ANALYSIS
Failure and flooding at Storm Lift Statiofi No. 15 could result from a power failure or storm flows over the station
capacity. Flooding of the station would result in the loss of the station and significant costs due to damaged
electrical panels, controls, and pumps. Planned improvements to reduce these risks are:
Installation of a back -up power generator to run all or a portion of the pumps
Installation of an electronically activated gate that reduces discharge to the station during flood events
Sealing the dry portion of the station so that stormwater cannot enter through drains connected to the wet well
The current Consultant Roster was reviewed and three firms were short- listed to perform this design. The firms
were: KPG, PACE Engineers and Parametrix. PACE, Inc. was selected as the firm that best met the requirements
for this type of project as PACE has performed similar work for other cities. PACE also completed the Drainage
Study for this pump station in 2010. Staff met with the proposed Project Manager and developed a scope of work
that includes design upgrades to the station.
BUDGET SUMMARY
This project will be funded through the 412 Surface Water Fund.
Cost Budci
PACE Engineers, Inc. 59,839.00 60,000.00
RECOMMENDATION
The Council is being asked to approve a Consultant Agreement with Pace Engineers, Inc. in the amount of
$59,839.00 for consideration at the February 28, 2011 Committee of the Whole meeting and subsequent March 7,
2011 Regular Meeting.

SCOPE OF SERVICES
STORMWATER PUMP STATION 15 IMPROVEMENTS
Project Understanding
The existing Lift Station No. 15 serves the Tukwila south property. The general boundaries of the
Tukwila south property are South 180 Street to the north, I -5 to the west, Green River to the east
and South 204 Street to the south. Lift Station No. 15 was constructed in the late 1970's and has a
total capacity of 43.7 cfs (19,614 gpm). Currently, Lift Station No. 15 conveys stormwater flows
from the Northeast Basin which is mostly commercial. It will also take future flows related to the
new development to the south. To date there have been no major reports of mechanical problems
with the lift station.
There is currently no on -site emergency back -up power if there were to be a complete failure of the
pumps due to a power outage. To resolve this issue the City has requested PACE provide:
Bid ready contract documents for the installation of a 600 kW standby generator with a
1,000 gallon subbase -fuel tank adjacent to the lift station to provide power to the pumps
during power outages.
Provide drawings to seal the electrical room from the wet well
Provide power to the new actuated sluice gate that will be constructed as part of the North
Pond.
Evaluate the cost and benefits to replace the existing motor starters with VFD's and the
replacement of the existing control panels.
Scope of Services
This proposal includes necessary civil and electrical engineering services through the design phase
of this project. PACE will be the prime consultant for the entire Scope of Work and will oversee and
administer this Scope of Work. PACE will complete all civil engineering and survey services in-
house. PACE will subcontract with Follett Engineering for the electrical engineering portion of the
project. Based upon our discussions we have not included the services of a professional land
acquisition specialist on this project. If during the course of the project, a specialist is required to
assist with obtaining an easement for the generator location the scope and budget would need to be
modified accordingly.
We anticipate starting this work immediately and proceeding on a preliminary layout to submit to the
City for review. The estimated cost for this work is approximately $59,839 (see Exhibit B). The
budget is based on our 2011 rates.
SCOPE OF WORK
Task 1- Project Management /Coordination /Meetings
PACE will provide administration and coordination of the project. The following items are
included in this task:

Right of entry to the site will be provided by the Client.
The City will provide available as -built drawings of existing pump station and the adjacent
strip mall.
The limits of the survey will include the southern half of the parking lot between the two
driveways and including two rows of parking stalls in a northerly direction. The existing
parking stall locations will be surveyed along with all surface features and subsurface utilities
as located in the field. The survey will extend across S 180 Street to the proposed location of
the new sluice gate.
Task 3 Preliminary Design
PACE will prepare a preliminary layout of the proposed improvements to submit to the City for
review and comment. This work includes:
Prepare preliminary site plan for the proposed generator and appurtenances.
Utilize lift station as- builts provided by the City to prepare details associated with
sealing of the electrical room from the wet well.
Preliminary layout of the CMU wall and access gate to enclose the generator.
Prepare preliminary electrical site plan with generator and conduit placement.
Instrumentation and control drawings for communication and operation of the
generator.
Prepare preliminary construction cost estimate.
Task 4 Final Design
Based upon City comments on the preliminary design as well as input from the property owner,
PACE will prepare the final design and contract bid documents in accordance with City standards
using the City's standard template and the most recent version of the Washington State Department
of Transportation `Standard Specifications for Road, Bridge and Municipal Construction. The design

Estimate of Probable Construction Costs
PACE will incorporate any City forms or special bid /construction requirements within the bid
document. It is assumed that the City will advertise, open bids and award the project with
support from PACE.
Task 5 Electrical Pre Design
Follett Engineers will prepare the following electrical design and evaluation:
Determine /confirm the size of generator needed to run 4- 150HP pumps and other
appurtenances.
Determine automatic transfer switch (ATS) size and options including interface with the
existing system.
Develop options to replace the motor starters with VFD's.
Review the existing control system and develop alternative analysis for replacement.
Prepare preliminary electrical drawings.
Prepare a preliminary construction cost estimate of the above items
Summarize the above items in a Technical Memorandum.
Task 6 Final Electrical Design
Follett Engineers will prepare the final electrical design for the new generator and appurtenances
based upon review comments from the City. This task excludes final design on converting the
motor starters to VFD's and the control pan replacement design. Both of those items are optional
design elements based upon city comments and available construction budget. If the City
decides to add these items to the scope of work the fee estimate would need to be adjusted
accordingly/
Task 7- Easement Acquisition
PACE will negotiate with the property owner for a permanent easement at the location of the
proposed generator. Work under this task will include:
PACE will secure the latest title report on the property
PACE will prepare Legal exhibit and for the proposed easement as needed.
Communication with property owner on the need and benefit of the easement.
Determine assessed value of easement based on current square footage value.
