Request Commission authorization for the Executive Director to execute a change order to
Contract MC-0319013 Electric Utility Supervisory Control and Data Acquisition at Seattle-Tacoma
International Airport (SEA) to add up to 180 Calendar days to the Contract Duration for impacts
due to Covid related supply chain delivery delays of critical material. (CIP #C800699)
This change order requires the addition of up to 180 calendar days to the Contract Duration. 
Commission action is required under the General Delegation of Authority because the additional
time being added to the contract is over 60 calendar days.  No additional project funding is
included with this request. 
Description of Change 
This change order will revise the contract completion date and settles all claims due to impacts
caused by Covid related supply chain delivery delays of critical Port furnished material.
This project is installing  an industrial computer system to allow for the safe operation,
monitoring, and control of the electrical power distribution system at SEA. This SCADA system is
located throughout SEA providing a complete, fault-tolerant control and data acquisition system.
The SCADA system, when completed in 2023, will serve 26 medium-voltage supply power
distribution centers (12.4kV – 480V) and two utility substations (12.4kV) and will enable
compliance with current electrical safety regulations.
On July 15,2021, the Port executed a construction contract with VECA Electric & Technologies 
the amount of $2,917,225.00 with a contract completion date of January 6, 2023. The Contract

has experienced cost growth, due to several Change Orders for design changes to accommodate
differing site conditions, and operations and maintenance requirements. Additional ly delays in
delivery of critical material has occurred due supply chain issues for which the Contractor is
entitled to additional time. As a result of these material delays, VECA notified the Port of potential
time impacts to the contract Substantial Completion date of up to 147 calendar days. Discussions
with the Contractor are ongoing and further material delays are possible, hence our request for
up to 180 days. Upon agreement, this Change Order will encompass all additional time and cost
due the Contractor as a result of the material deliver delay. 
Diversity in Contracting 
The Woman and Minority Business Enterprise (WMBE) aspirational goal is 7% for the
construction project and the contractor is on track to meet this goal.

Alternative 2 – Authorize the issuance of the Change Order to extend the Contract duration by
up to 180 days. If executed,  this change order will settle all outstanding claims between the
Contractor and Port related to provision of the Port furnished material.

additional Contract Time. 
(2) This time extension is necessary for reconciliation of the schedule delay. 
(3) The Contractor will not have to submit a claim of protest.
