ACTION REQUESTED:
Request authorization for the Chief Executive Officer to issue Change Order Number 054 for
Contract MC-0316219, East Marginal Way Grade Separation project in an amount not to exceed 
$371,000 to replace approximately 200 lineal feet of existing 20-inch diameter water main that
runs adjacent to the project site. The total project cost is $21,151,058. No additional project

SYNOPSIS:
This project is for the construction of a new vehicular overpass structure to separate vehicular
traffic from rail traffic at the intersection of lower Spokane Street and East Marginal Way. The
project includes: 
Pavement improvements at the existing street connections 
Realignment of a portion of Spokane Street surface street to pass under the new overpass 
Installation of an earthquake drain system under the retained fill

This change order provides the replacement of approximately 200 feet of 20-inch diameter water 
main adjacent to the project site. The installation activities related to the earthquake drain
system at the northern project boundary caused slight settlement of the existing water main.
Seattle Public Utilities is requiring the replacement of the affected water main. Replacement of
the existing water main needs to be completed during a period of low water usage as this main
feeds a large portion of the West Seattle neighborhood.
The change order will be issued for a not-to-exceed amount of $371,000 and costs will be
reconciled in a future change order after the Port has completed evaluation and negotiation with
the contractor. 
The source of funds for this change order would come from the contract construction
contingency, requiring no additional funds. The contract currently has an executed change order
rate of 3.81%, this change order represents an increase of 1.92%. 
BACKGROUND:
The East Marginal Way Grade Separation project is a roadway improvement project near the
East Marginal Way/South Spokane Street intersection. The grade separation is a complex
geometry bridge structure that moves surface traffic above both Burlington Northern/Santa Fe
and Union Pacific Railroad tracks. The completed project will service north, south and
eastbound traffic, improving freight mobility for Terminals 5, 18, and 30 as well as providing 
safer transit for all traffic with the elimination of railroad crossings in this vicinity.
Mowat Construction Company was the low bidder with contract execution on October 26, 2009.
The contract amount is $18,250,482.70 with a contract completion date of September 14, 2011. 
As there have been complications encountered with the City and nearby stakeholders, the final
configuration is currently being redesigned and has delayed the completion of the project. This
uncertainty has affected the ability of Port staff to predict an end date for this project.
The grade separation is open to traffic in an interim condition with work remaining to be
completed in the west and south approaches that would allow northbound traffic on the structure.
Due to weather and asphalt supply issues, the project was placed in suspension starting
November 29, 2011, with work resuming on January 3, 2012. Based upon the remaining work,
this project is anticipated to be complete during late first quarter of 2012. Time impact analyses
are currently being performed on all remaining design changes and time impact will be awarded
as appropriate for each issue as they are resolved. 
CHANGE ORDER DESCRIPTION: 
The following information relates to the pending change order scope and cost: 
Change Order No. 054 
Scope of work: The contractor shall provide labor, materials, and equipment to remove a section
of the existing 20-inch diameter water main line and install a 20-inch restrained joint ductile iron
pipe (RJDIP) water main line as directed by Construction Bulletin 051.1. The contractor shall
coordinate all work with Seattle Public Utility (SPU).

COMMISSION AGENDA 
Tay Yoshitani, Chief Executive Officer

Page 3 of 4 
All cement lined 20-inch restrained joint pipe fittings shall not require any special tools for
assembly and shall comply with the City of Seattle Standard Specifications 9-30.1(6)D. 
The contractor shall install the 20-inch diameter RJDIP water main line in accordance with City
of Seattle Standard Specification Section 9-30, "Water Distribution and Transmission Materials." 
The contractor shall proceed for a total amount not to exceed $371,000. Costs will be reconciled
in a future change order after the Port completes the proposal evaluation and negotiation with the
contractor.
As there are multiple issues affecting the completion of the work, additional time may be granted
by separate change order after an analysis of whether this specific issue contributed to
prolonging the contract duration. 
JUSTIFICATION: 
SPU has required the replacement of the affected portion of water main as a result of the
earthquake drain installation activities near the water main. Although, in the opinion of Port
staff and the designer of record, the settlement is minor and has not weakened or shortened the
anticipated lifespan of the water main in question, SPU has maintained its position. The City of
Seattle is the eventual owner of this project, and failure to complete this work may affect the
turnover of this project to the City. 
FINANCIAL ANALYSIS: 
The funds to pay for this change order are part of the project construction contingency funds that
were included in previously approved authorizations of $50,700,000. The project authorization
includes grants from both Freight Mobility Strategic Investment Board (FMSIB) and the
American Reinvestment and Recovery Act (ARRA). No additional project funds are being
requested as a result of this change order.
