ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to amend the Walker Parking
Consultants (Walker) Professional Service Agreement up to $603,590 for design support during
construction and provide notification to the Port of Seattle Commission in accordance with RCW
53.19.060 that the amended amount exceeds 50% of the original contract not to exceed value of
$100,000. The history of the Walker Parking Consultants Agreement was briefed to the
Commission on April 5, 2011. With the execution of this amendment, the value of the Walker
Agreement will be $32,271,911. The completion date remains December 31, 2012. No new
budget is requested to amend this Agreement as funds have been previously authorized in the
Rental Car Facility (RCF) program budget. 
SYNOPSIS: 
In order for the Port to complete the RCF and the Off-Site Roadway Improvements (ORI)
projects, Walker's service agreement must be amended for additional budget to continue to
provide support services through completion of the projects, opening day of April 19, 2012, and
project closeout. As required by Resolution No. 3605, as amended, this memorandum also
constitutes notification to the Commission that the amended amount exceeds 50% of the original
not to exceed contract value. Funds supporting this amendment have been previously authorized 
and there is no increase to the overall RCF program budget. This memorandum will be placed on
file for public inspection at the Port's bid desk.

BACKGROUND: 
In fall 2001, the Port of Seattle executed a contract with Walker for design and construction
support services for the RCF and ORI projects. The original procurement anticipated the total
cost of this work to be $15 million; however, the initial contract value was only $100,000. To
control cost and effectively manage the contract, a series of amendments was intentionally
planned and issued to add portions of the original scope in logical phases as a way to efficiently
complete the design and provide construction support services. Since the RCF program has been
stopped and restarted several times since it began in 2001, the overall cost for design and
construction support services has increased. The original estimate of $15 million was estimated
based upon an RCF construction value of $110 million. The RCF construction value has
increased to $230 million. At each of the major project phases, and with each stop and restart,
the Commission has authorized the additional funds necessary for design and construction
support services to support the RCF program. 
On April 5, 2011, staff briefed the Commission on the history of the Walker contract and Port
procedures in place at the time of each amendment and what might have been done differently
under current procedures. At the time of that briefing, Walker's contract value was $31,466,116
and the completion dates for the RCF and ORI were November 15, 2011, and March 28, 2012, 
respectively. Since that time, there have been two further amendments to the contract: 
Amendment 34 was executed on May 17, 2011, for an equitable adjustment in the amount of
$202,205 for design claims, 
Amendment 35 was executed on November 11, 2011, for a no-cost time extension to extend
Walker's contract until December 31, 2012.
The current amendment request is required due to the construction schedule extension granted to
Turner Construction Company revising their contract completion to February 13, 2012, as
authorized by the Port Commission for 80 days on July 26, 2011, and by staff executing Change
Order No. 893 on September 13, 2011, for an additional 10 days. In addition, with staff setting
April 19, 2012 as the opening date for the RCF, the ORI contract completion date must be
extended to this date for the installation of revised freeway signage that can only be done the
night of the opening cutover to the new facility. These project time extensions require Walker to
continue to provide design services during final construction. The current Walker contract value
is $31,668,321. With the execution of this amendment, the total contract value would increase to
a value up to $32,271,911. The contract completion date remains December 31, 2012, per
Amendment 35. 
SCOPE OF WORK AND SCHEDULE: 
The scope of services for this Amendment is included in this request and is a continuation of
design support services during construction described below.
