ACTION ITEM                            Date of Meeting      October 22, 2019 
DATE:     October 1, 2019 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Jim Rosmond, Manager, PCS Construction, Port Construction Services

SUBJECT:  Port of Seattle Fire Station House HVAC Upgrades (CIP #C800100) 
Amount of this request:                  $55,000 
Total estimated project cost:            $350,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to: (1) approve an increase to the
funding of design, construction, and permitting of the Port of Seattle Fire Station HVAC Upgrades
project in the amount of $55,000 for a total of $350,000; and (2) resume the work to complete
upgrades to the Fire Station heating system under a Small Works contract, presently in progress,
and as early as practicable prior to the onset of lower seasonal temperatures. 
EXECUTIVE SUMMARY 
The Port of Seattle Fire Station HVAC Upgrades Project (WP 105985) was designed, permitted,
and activated for construction to address a serious problem with the air quality within berthing
and administrative spaces in the existing Aircraft Rescue and Fire Fighting (ARFF) building. The
scope of this project calls for the replacement of two interior humidifiers, installation of one new
humidifier, and replacement of valve assemblies for 15 existing duct coil units in the ceiling areas
throughout the building. 
Work was begun as a Small Jobs Capital project funded at $295,000. Due to discovery of
unforeseen conditions, Port Construction Services has increased the project budget to $350,000,
which triggers the need for Commission authorization under the General Delegation of Authority. 
JUSTIFICATION 
This project originated out of the need to address poor interior air quality, particularly health and
comfort issues of low humidity and inadequate heating in the building's three berthing areas.
The 40-year-old HVAC system has experienced failing duct heating coils and in-duct humidifiers
in the berthing spaces.   During winter months when outdoor air is excessively dry, the
conditioned air supplied to fire station dormitories trends to the low end of the Occupational
Safety and Health Administration (OSHA) acceptable range (20 percent to 30 percent), and
occupants have complained of ill effects such as itchy skin, irritated throats, and dry eyes. The

Template revised January 10, 2019.

Fire Department relayed the need to the Aviation division to act on improving conditions in the
Station House in response to increasing complaints from the firefighters.  Since a protracted
design and construction cycle would jeopardize the ability to resolve the issue before the heating
season began this year, a Facilities and Infrastructure (F&I) design and Small Works contract
managed by Port Construction Services (PCS) was believed to be the best available project
delivery option to affect the repairs in time.
Diversity in Contracting 
The contractor currently performing the HVAC upgrades at the fire station under Small Works
Contract #SW-0319867, is a Minority Business Enterprise (MBE). 
DETAILS 
See Executive Summary 
Scope of Work 
The scope of work for this project is for the design and installation of the new humidifiers and
heating coil valve assemblies above the ceiling area throughout the fire house building.
Additionally, work to relocate existing utilities is required in some areas above the ceiling to
install the new equipment.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Suspend current Small Works contract, demobilize and remobilize contractor
after authorization to extend and fund additional change order work is granted. 
Cost Implications:  Contract will incur charges for the effort to pull equipment, labor and
materials off the site and then remobilize at a later date. Inefficiencies will also be realized for
possible work during the heating season to provide temporary heat and extended rental costs of
equipment and material cost escalations. Impact estimated to cost approximately $20,000 in
contract costs and additional cost of $10,000 per month for temporary heating measures. 
Pros: 
(1)   Port of Seattle will retain existing contractor for continuity and resumption of contract
work without need for resoliciting a new contract and orienting a new one to take over. 
(2)   Integrity of normal Port authorization procedures and protection from unauthorized
cost overruns. 
Cons: 
(1)   Work will be pushed into the "heating season" when building occupants will need to
rely on a temporary heating system and probably gaps in heating service during
construction. 
(2)   Project cost will escalate proportionate to the period of delay in resuming the contract
work. 
This is not the recommended alternative. 
Alternative 2  Terminate the incumbent Small Works contract for convenience and resolicit the
contract as a Major Works Contract project. 
Cost Implications: This option will increase costs and delay the start of work well into or after
the heating season.  This option will escalate costs for not only a new contract and the
management of it, but also termination costs of the incumbent small work contract. The overall
cost is estimated to be approximately $650,000 ($200,000 in sunken costs of the current contract,
$50,000 for temporary heating measures over the autumn/winter, and $400,000 to follow on
with another contract to complete the work). 
Pros: 
(1)   A repackaged contract may be able to address additional deficiencies by completely
modernizing the current HVAC infrastructure. 
(2)   The project would follow regulatory procedures for contract solicitation and award. 
Cons: 
(1)   Work to upgrade HVAC system components is nearly 50 percent complete. Termination
would disregard final completion of work which is projected in late October 2019. 
(2)   Cost.  Completion of work on the present course is roughly half of what it will be to
abandon the current contract and transition to another (next year). 
(3)   This option would terminate the work currently being performed by a DBE contractor.
A rebid of the contract does not assure this opportunity again.

Meeting Date: October 22, 2019 
This is not the recommended alternative. 
Alternative 3  Continue work, presently in progress at roughly 50 percent completion, and
approve additional funding, with Commission approval, of the current Small Jobs Capital project
to completion, expected late October/early November. 
Cost Implications:  The Small Jobs Capital project is presently funded at $295,000. This work can
be completed with a supplement of $55,000 for a total cost of $350,000. 
Pros: 
(1)   Work will be completed at earliest opportunity with the need of little or no temporary
heating measures for the autumn months. 
(2)   This option affords the most economical solution to the health and safety issue
concerning the air quality issues inside the fire station. 
(3)   The work will be completed by a MBE contractor. 
Cons: 
(1)   The Port will forego an opportunity to implement the replacement of a more thorough
and contemporary HVAC system in the fire station house.  This alternative can be
viewed as a provisional repair to a dated system that has potential for more HVAC issues
until the station is replaced/relocated. 
This is the recommended alternative.
