SUBJECT:  Request for Funding Increase for the T91 Lift Station #4 Replacement 
(Project #104358, CIP #C800186) 
Amount of This Request:  $65,000         Source of Funds:    General Fund 
Est. State and Local Taxes: $6,000          Est. Jobs Created:   N/A 
Est. Total Project Cost:    $315,000 
ACTION REQUESTED: 
Request Commission authorization (1) for the Chief Executive Officer to amend the Terminal 91
(T-91) Lift Station #4 Replacement project budget by $65,000 for a total project budget
authorization of $315,000; and (2) for use of Port crews to construct the project. Additional
funds for the project are available due to under-spending in other Seaport small project CIPs.
SYNOPSIS: 
T-91 Sewer Lift Station #4 serves all the buildings on Pier 90 (P90) and the shortfill. Lift
Stations are used to reduce pipe depths over a length of pipe. They 'reset' the pipe depth by
pumping sewage from a lower to a higher elevation to accommodate long gravity sewer pipe
runs without having to install and maintain pipe at prohibitive depths.The existing lift station was
installed in 1981 and was repaired with a temporary fix in 2007, following a major equipment
failure. 
This project will allow sewer system improvements and complete replacement of Sewer Lift
Station #4 at Terminal 91. The project scope replaces the existing lift station and resolves
system deficiencies. The project is currently budgeted in the 2009 Seaport Small Project CIP
#C800186. The authorized budget for the lift station replacement project is $250,000. The
authorized project budget was based on rough order of magnitude design and construction cost
estimates determined during preliminary design. Subsequently, in-house engineering completed

design, and construction cost estimates were determined. The project cannot be completed within
the authorized budget. Port staff are requesting an additional $65,000 to complete the project. 
BACKGROUND: 
Sewer Lift Station #4 is located south of the Resident Engineers trailer on Pier 90. It is the final
sewage collection and discharge point from the buildings on P90 and the shortfill to the City
sewer main. The existing pump and controls are portable, and were installed as a temporary fix
in 2007 following a major failure of the original equipment. 
Replacement of the lift station was identified as a potential project and included in the 2009
Seaport Small Project CIP. The project was activated, after authorization to begin design, in
June, 2010. Since 2010, shifting project priorities have resulted in delays of the lift station
replacement project. Operation of the temporary pump allowed staff to defer this item and
prioritize a permanent solution to lower on the project list. As an example, the lift station project
competed for resources with the T91 Water Main Replacement project and the water main
project was given priority. Now, the temporary equipment is near the end of its service life and
the project shouldn't be delayed further. 
During design, the scope of the project increased to include improvements to the sewer system
feeding the lift station in order to eliminate system deficiencies. Deficiencies include: 
A wet well that is too shallow to effectively receive discharge from surrounding buildings 
Improperly sloped sewer pipe causing sewage backups to the manholes serving Building 86 
Rather than a simple pump replacement, the scope of design included improving the sewer
system feeding the sanitary lift station. The project scope required more design work and field
investigation than originally anticipated, as well as an increase in construction budget. Design is
now complete and project costs are more than originally estimated. 
Port of Seattle Engineering completed design and will provide engineering support services 
during construction. Marine Maintenance and PCS will partner to construct the project.
Procurement of equipment and materials, and scheduling of construction will begin following
Commission authorization. 
PROJECT JUSTIFICATION: 
T-91 Lift Station #4 is well past its service life. It was installed in 1981. The typical service life
for a lift station is 15 to 20 years. The portable pump and controls, which were installed as a
temporary repair in 2007, periodically break down and require repair. This lift station is critical.
It is the final sewage collection point from the buildings on P90 and the T-91 shortfill prior to
discharge to the City sewer main. It is essential that it be reliable.

Project Objectives: 
Install new, reliable sewer lift station 
Install deeper wet well 
Correct sanitary sewer line slopes 
Provide easy to maintain system 

PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
The scope of work is to replace existing sewer lift station #4 with a new lift station and improve
the pipe system feeding the lift station. The work includes replacement of a wet well,
submersible pumps, pump controller, valve vault, and replacement and regrading of pipe feeding
the lift station. 
Schedule: 
Design of the lift station is complete. Procurement of equipment and materials will likely require
four to six weeks. Construction is estimated to last between four and six weeks and is expected to
be complete by the end of October 2012.

Budget Status and Source of Funds: 
This project was included in the 2012 approved budget as a Small Capital Project under
CIP# C800186, in the amount of $250,000. The additional $65,000 in funding needed to
complete this project is expected to be available due to timing differences in other planned Small
Capital projects. 
This project will be funded from the General Fund.

discount rate 
Key risk factors      Construction costs may increase if required work is more
extensive than currently known. This risk is deemed to be
relatively low, as the design process for this project is complete
and the scope of work necessary is well defined. 
Project schedule could be delayed due to project complexity,
weather, and the need to minimize disruptions to terminal
operations and existing tenants/customers.

Effect on business   This asset replacement project will not generate any incremental
performance       revenue. However, it will eliminate disruptions due to sewer lift
station failures to terminal operations, tenants, and customers.
Incremental depreciation expense from this project is estimated at
$16,000/year, based on a 20 year asset life. NOI after Depreciation
will decrease by the associated depreciation from this project.

ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1: Stop work on the project. Do not replace the lift station or make system
improvements. The lift station will continue to have failures and require repair. Sewage backups
will occur. This is not the recommended alternative. 
Alternative 2: Continue with the planned T-91 Lift Station #4 Replacement Project.
Authorization of an additional $65,000 for a total project authorization of $315,000 will allow
sewer system improvements and complete replacement of the lift station. This is the
recommended alternative.
