eGSE Electric Charging Stations Change Order

AGENDA MEMORANDUM                        Item No.          8g 
ACTION ITEM                            Date of Meeting    September 13, 2022 
DATE:     August 22, 2022 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Janice Zahn, Interim Director of Engineering 
SUBJECT:  Electric Ground Support Equipment (EGSE) Charging Stations (CIP #C800335) 
Amount of this request:                       $0 
Total estimated project cost:         $38,100,000 
Request Commission authorization for the Executive Director to execute a change order to
Contract MC-0319135 Ground Support Equipment Electric (eGSE) Charging Stations Phase 2A to
extend the duration up to 150 calendar days to the Contract. (CIP #C800335) 
This change order requires the addition of up to 150 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 Port and
Contractor impacts to the project schedule due to delays caused by supply chain issues and
design changes. 
When this contract is completed in December 2022, this project will have installed 100% of this
programs new electric charging infrastructure to support the EV charging needs of airline
electric ground support equipment (baggage tugs, belt loaders, pushbacks, etc.). Our airlines
currently use approximately 600 Ground Support Equipment (GSE) and about half of those have
been converted to electric to-date. 
When completed, the full project will reduce approximately 9,000 tons of carbon per year and
almost 400 tons per year of criteria pollutant emissions from ground support equipment. It will
also reduce airline maintenance costs, save fuel costs, and contribute to the Century Agenda
goal to “Be the greenest and most energy efficient Port in North America.”

Meeting Date: September 13, 2022 

On October 20, 2021, the Port executed a construction contract with Valley Electric Company
Inc. in the amount of $2,339,410.00 with a contract completion date of July 29, 2022. The
Contract  has  experienced  schedule  growth  due  to  significant  design  changes  and  to
accommodate procurement of proper equipment. Discussions with the Contractor are ongoing,
but upon agreement, this Change Order will encompass any additional time and cost due the
Alternative 1  –  Do not authorize the issuance of the Change Order, continue further
negotiations until negotiations are complete. 
(1)   Further negotiations may result in a bi-lateral agreement with the Contractor. 
(1)   Does not start the timelines in the contract to begin the contractually established
tiered dispute resolution process.
(2)   Delays project closeout and increase Port costs to continue negotiations.
(3)   Creates a risk potential for litigation. 
(4)   Will still require the project to return to Commission for approval of a future change
order to resolve the contract days in excess of 60 days. 
This is not the recommended alternative. 
Alternative 2 – Grant the Contractor additional Contract Time to accommodate the Port caused
delay related to the design changes and supply chain issues. 
(1)   This is a Port caused, excusable and compensable delay. The Contractor is entitled to
the additional Contract Time. 
(2)   This is a fair resolution. 
(3)   The Contractor will not protest. 

(1)   The Port will pay extended overhead costs. 
This is the recommended alternative.
