DATE: February 4, 2015 CONSENT AGENDA
SUBJECT: APPROVE SOLE-SOURCE PURCHASE OF EQUIPMENT FOR
RUNWAY PROJECT
FROM: David H. Ready, City Manager
BY: AIRPORT
SUMMARY
This action considers the authorization of a sole source purchase of equipment for the
upcoming Palm Springs International Airport main runway pavement rehabilitation
project.
RECOMMENDATION:
1. Approve the sole source purchase of two (2) Pulsed Light Scope Approach
Indicators (PLASI) from DeVore Aviation Corp. in the amount of $29,048.50,
inclusive of shipping and applicable taxes.
2. Authorize the City Manager to execute all necessary documents as required.
STAFF ANALYSIS:
On April 16, 2014, Council approved the Federal Aviation Administration Grant and
professional services agreement for the summer 2015 main runway pavement
rehabilitation project at Palm Springs International Airport.
In order to orchestrate this project with minimal impact to aircraft operations, the project
must be conducted during the airport's least busy time of the year. Based on the
current schedule, the plan is to award the project in April, pending FAA's grant
authorization program timing, and complete the construction over the course of the
summer.
Because of the tight timing of all phases of this project, and the long lead time of some
important equipment necessary for the temporary runway that will replace the main
runway during construction, it is necessary to make an equipment purchase ahead of
the contract award. There is a lead time of several months for this specialized

navigational aid equipment and if it waited until after the bid and award this timeframe
would not be conducive to the project's timing objectives.
There are two Navigational Aids that must be used to demark the temporary runway
and provide the visual approach assistance to landing aircraft. Although the purchase is
up front, these units will still be installed by the contractor who wins the construction bid
and FAA will flight check and calibrate the units prior to the construction commencing.
Based on the analysis provided by the Airport's professional engineering design firm for
the project, the PLASI units from Devore Aviation Corporation are the only devices that
meet the specifications and they are the only authorized manufacturer. As such, staff is
requesting, pursuant to the provisions of section 7.04.020, that the City Council approve
a sole-source purchase of this specialized equipment that is required for the project.
FISCAL IMPACT:
Because these units are essential to the project, they are eligible for funding by the FAA
construction 90/10 grant. The airport fund No. 416-6601-56172 will be used to make
the purchase and staff will then orchestrate reimbursement through the grant funds.
