SUBJECT:  Increase Technical Vendor Contract (CIP #800844) 
Amount of this request:                       $0 
Total estimated project cost:         $28,500,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director  to increase the Perimeter
Intrusion Detection System  contract (S-000319688)  with Siemens by $375,000 for a new
contract amount of $5,411,000. In accordance with Port policy, this request, and a previously
executed change order, constitutes notification to the Commission that the amended amount
of the technical contract exceeds 10% of the original not to exceed contract. 
SUMMARY 
In January 2019, the Port Commission authorized a project to procure and implement a
Perimeter Intrusion Detection system (PIDS) for the Seattle-Tacoma International Airport (SEA)
perimeter. System implementation and construction design are currently in progress with
construction authorization estimated for fourth quarter 2022. 
This request for a contract increase with Siemens, the PIDS system vendor, is to procure
hardware   and   implementation  services  to  ensure  PIDS  system  redundancy.  Dual
communication path and hardware redundancy of the in-scope SEA perimeter is required to
ensure the system is configured at the highest performance and quality level given the variety
of tactical, unplanned, and environmental situations that could occur. 
This request utilizes program contingency prior to authorization for construction. Should final
construction estimate require additional contingency, it will be requested with construction
authorization expected in the fourth quarter of 2022. 
There are no attachments to this memo.
