Date of Meeting
April 14, 2009
DATE: April 6, 2009
TO: Tay Yoshitani, Chief Executive Officer
FROM: Dakota Chamberlain, Director, Seaport Project Management
SUBJECT: Request authorization for construction and for approval to advertise a major works
bid package based on the design prepared and completed for Bird Control systems
at Smith Cove Cruise Terminal.
SYNOPSIS
Smith Cove cruise terminal is situated in a prime area for Seagull and other pest bird activity.
Due to the seasonal nesting activity of these birds, it is important for the terminal to have systems
in place to prevent nesting and to discourage birds from roosting above areas which will
experience heavy cruise customer traffic.
BACKGROUND
In January of 2009, the Port of Seattle, using an existing open order contract, executed a service
directive for a design that identified and proposed solutions for pest bird activity. Using the
Port’s drawings, the designer created a comprehensive plan to address the locations most
vulnerable to bird activity. 4 distinct areas were identified and appropriate systems/materials
specified for each section.
PROJECT DESCRIPTION/SCOPE OF WORK
The scope of work developed includes the following:
BUILDING ROOF
Bird netting will be installed upon the air handling units and the skylights to prevent gulls from
getting close enough to the units to be out of the wind. Uprights will be installed upon the
corners of the skylights and air handling units that extend upward and outward from the
structures. These uprights will support an installation of bird netting that will protect the
skylights and units, while allowing easy access for maintenance. A bird shock track system, a
standard and harmless device used to prevent Gulls from landing on the edge of the roof, will run
around the perimeter of the roof.

BUILDING CANOPIES
To prevent perching, roosting, or nesting by any species of bird above the walkways or other
areas that will be occupied by passengers, ¾ inch polyethylene bird netting, supported by a
stainless steel cable/bracket system will be mounted under the North Entrance Canopy, and both
the East and West Balcony Canopies. Tension wire, which prevents birds from perching, will be
installed upon any surfaces that will be below the plane of the netting. The bird netting is
uncomplicated to remove and replace, allowing for future maintenance needs.
ACCESS / EGRESS STAIRWAYS
There are four separate stairways to be treated. The deterrent in these locations will be bird
netting installed across the underside of the ceiling in the same manner as that used under the
adjacent canopies of the exterior passenger balconies. The netting will prevent entry into the
areas behind the support beams near the corners and along the top edges .There are some flanges
that are too low to be protected by the netting and these will be protected by installing a bird
slide on them. A bird slide is a product which creates an angle at which birds are unable to perch.
There are beam tops that will be protected by installing tension wire (bird wire) upon them.
SOUTH EXTERIOR BEAMS (SUNSCREENS)
Tension wire and bird slide will be installed on the exposed beams in this area to prevent birds
from perching and roosting.
ALTERNATIVES CONSIDERED/RECOMMENDED ACTION
1. Do nothing. Without action, not only will nesting and roosting be an issue, but the associated
droppings will become a problem. Bird droppings can be extremely toxic and disease laden
and could easily be tracked in to the cruise terminal. This is not the recommended alternative.
2. Install a comprehensive bird control system to discourage and prevent birds from nesting at
the Smith Cove Cruise Terminal. This is the recommended alternative.
FINANCIAL IMPLICATIONS
Cost Estimate
The cost estimate for this work is $185,677. However, with the addition of sales tax, the estimate
becomes $203,316.31.
Source of Funds
The capital costs incurred will be allocated to the work project budget of the existing
CIP 800085. No additional funds are requested.

cruise call schedule.
PREVIOUS COMMISSION ACTION
On February 14
th
, 2006, the Commission authorized $10,850,000 for staff to proceed with
environmental reviews, design, and permitting of the T25/30 container terminal and the relocated
