future revenue bonds

ACTION REQUESTED:
Request Port Commission authorization for the Chief Executive Officer to execute a major
works construction contract to install one new Passenger Loading Bridge (PLB) at Gate B1 and
to refurbish one PLB at Gate B11 for the amount of $597,093. No additional funding is
requested to execute this contract. 
SYNOPSIS:
This project represents the continuation of the one-time realignment of air carrier operations that
is taking place at the Airport and is included in the 2013-2017 capital budget and plan of finance.
As part of the ongoing Terminal Realignment program, this project will install one new PLB at
Gate B1 where one does not currently exist. It will also purchase and refurbish the 23 year old,
airline-owned PLB at Gate B11 thereby bringing it up to current code and Airport PLB standard.
On July 24, 2012, the Port received two bids for this scope of work as a Major Public Works
project, and both bids were more than 10% over the engineer's estimate. Port staff decided to rebid
this work, as authorized by the Commission on October 2, 2012, and revised the engineer's
estimate to $537,948 for the rebid work. The Port received four bids on October 30, 2012, all of
which exceeded the engineer's estimate by more than 10%. Staff has analyzed these bids and
has determined that they accurately represent the current bid market. Staff believes the low bid
of $597,093 by Lydig Construction offers a fair and reasonable price. Staff recommends that the
Commission approve the execution of this contract as provided for by Section 4.2.3.4. of
Resolution No. 3605, as amended, which requires Commission approval to proceed in the case of
a bid irregularity, such as the bid being greater than 10 percent over the engineer's estimate.

BACKGROUND: 
This project continues the next phase of PLB Replacement  Airline Realignment work for the
two affected gates at Concourse B. It further advances the Airport's objective to standardize on
John Bean Technologies AeroTech / Jetway PLBs and components.
On July 24, 2012, proposals from two bidders for this scope of work came in at $781,530 and
$776,776, which were 98% and 97% higher than the engineer's cost estimate. Changes were
made by Staff to the phasing of the work and the previous 6% Small Contractor and Supplier
participation requirement was also waived. The Commission authorized rebidding the revised
scope of work at the October 2, 2012 Commission meeting. However, the new bids seem to
indicate that the previous small business requirement was not a factor in bid price.On October
30, 2012, the Port of Seattle received four bids ranging from $597,093 to $825,335 as shown in
the table below. All bids were more than 10% over the engineer's estimate; therefore, in
accordance with Resolution No. 3605, as amended, staff is seeking Commission approval to
execute this contract. 
Contactor                  Bid                 Variance 
Lydig Construction                  $597,093                11% 
PCL Construction                  $629,271                17% 
Mowat Construction Company          $777,025               44% 
M D Moore Company Inc.            $825,335               54% 
Staff analyzed the engineer's estimate of $537,948 and identified three primary shortfalls
associated with the following items: 
Additional mobilization/demobilization costs arising from performing this scope of work
during the winter months. 
Necessary upgrades to the subsurface Industrial Wastewater System adjacent to the PLB
foundation at Gate B1. 
Need for additional work crew on the B11 refurbishment based upon previous experience
with similar work being completed at Concourse D. 
Based on the qualifying factors stated above and because all four bids were above the engineer's
estimate, staff believes the bid tendered by Lydig Construction accurately represents the current
bid market as well as a fair and reasonable price. Commission authorization to proceed with the
Lydig bid will also allow this scope of work to take place as scheduled.
The low bid amount exceeds the engineer's estimate by $59,145 or 11%. As a result of cost
savings realized on an earlier phase of this project no additional funding is being requested. 
Specific Commission authorization is required by Section 4.2.3.4 of Resolution No. 3605, as
amended, due to a bid irregularity, i.e., the bids being greater than 10 percent over the engineer's
estimate. This bid amount exceeds the engineer's estimate by $59,145 or 11%. As a result of
cost savings realized on an earlier phase of this project. no additional funding is being requested.

FINANCIAL IMPLICATIONS: 
Budget Status and Source of Funds: 
This project is included in the 2013-17 capital budget and plan of finance within CIP #C800467,
Passenger Loading Bridge Replacement  Airline Realignment with a budget of $14,874,000.
The funding sources will include existing 2010 revenue bonds and future revenue bonds. As
discussed at the plan of finance briefing on October 23, 2012, the Port plans to issue revenue
bonds in 2013 or 2014 to fund a number of projects. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative #1: Do Not Award Contract: Staff evaluated rejecting all bids for a second time and
re-advertising the contract which would seriously delay the project and interrupt the airline
realignment effort. Frontier Airlines is scheduled to be assigned to gate B1 and Virgin America
will be assigned to Gate B11 at the end of March 2013. Rejecting bids and re-advertising this

scope of work will seriously delay the project and these airline moves. This is not a
recommended alternative. 
Alternative #2: Award Contract: Based upon our technical analysis of the factors which
affected the bid prices, Port staff believes this bid price from Lydig Construction is fair and
reasonable. Staff recommends the Commission authorize for contract award. This is the
preferred alternative. 
OTHER DOCUMENTS ASSOCIATED WITH THIS REQUEST: 
None.
