Request Commission authorization for the Executive Director to execute a change order to
Contract MC-0319302 AOA Perimeter Fence Line Standards Compliance to add 103 Calendar days

date. (CIP #C800842) 
EXECUTIVE SUMMARY 
This change order requires  the addition of 103  calendar days to the Contract  Duration.
Commission action is required under the General Delegation of Authority because the Change
Order includes a time extension of more than sixty days. No additional project funding is included
with this request. 
Description of Change Order 
This change order revises the contract completion date and settles all claims due to Port and
Contractor impacts to the project schedule. 
Background 
The Airport Operations Area (AOA) perimeter fence line is the primary physical barrier into the
secured areas of commercial airports. Over the past years, other airports have experienced
several nationally recognized breaches in security that included accessing the AOA by climbing
over a perimeter fence. Seattle-Tacoma International Airport has also experienced this type of
trespass. There is a recognized need to improve security by increasing the level of difficulty for
unauthorized access through the AOA perimeter fence. 
On February 26, 2019, the Port executed a construction contract with Massana, Inc. in the
amount of $4,042,694.55. The Contract has experienced cost and schedule growth , due to 
multiple Change Orders for design changes to accommodate differing site conditions, and 
operations  and  maintenance  requirements,  which have  extended the  current  Contract
completion date to July 19, 2020.  Additionally, the Contractor requested and was granted a 41-

day contract extension due to a work stoppage related to COVID-19, which further extended the
Contract End date to August 29, 2020.  The actual date the Contractor achieved Substantial
Completion was December 10, 2020, 103 days beyond the contract specified date. This Change
Order includes a credit back to the Port of $131,879.22 for impacts to the Port due to late
completion. The current value of the Contract is $4,453,834.57.

FINANCIAL IMPLICATIONS 
There is no additional funding being requested with this action. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do not authorize the issuance of the Change Order, continue further Dispute
Resolution Processes. 
Pros: 
(1)   Further negotiations may result in a larger credit back to the Port. 
Cons: 
(1)   Delays project closeout and increase Port costs to continue negotiations. 
(2)   Creates a risk potential for litigation. 
(3)   Additional staff soft costs, potential legal expenses. 
This is not the recommended alternative. 
Alternative 2  Authorize the issuance of the Change Order to extend the Contract duration by
103 days.  If executed, this will be the final Change Order on this project and will settle all
outstanding claims between the Contractor and Port. 
Pro: 
(1)   Settles all claims between the Port and Contractor and allows contract close-out to
commence. 
Cons: 
(1) Eliminates potential additional credit to the Port. 

This is the recommended alternative.
