EXECUTIVE SUMMARY
Construction of the River Intake Pump Station (RIPS) was completed in 2015 as part of the Lake
Oswego-Tigard Water Partnership. The RIPS is a critical component of the water supply system
used to supply water to Lake Oswego and Tigard citizens. Installation of a fifth and final pump
at the RIPS will improve facility reliability and resiliency.

BACKGROUND
The RIPS facility was designed to ultimately house five, vertical turbine pumps. The initial
construction of the RIPS included the installation of four of the five pumps with space set aside
for a fifth and final pump. Although it was not initially anticipated that the fifth pump would be
added until later, it was decided that it is beneficial to install the pump at this time to provide
more flexibility at the pump station and allow the other pumps to be taken offline for repair
and maintenance.
DISCUSSION
Engineering Department staff contracted with local engineering consulting firm Black & Veatch
(BV) to prepare plans and specifications for installation of the fifth and final pump at the RIPS.
As the original engineer of record for design of the RIPS facility, BV was able to economically
update the original plans and specifications for purposes of soliciting bids from contractors for
this final pump installation. On November 20th and 22nd, the City published notice in the Daily
Journal of Commerce, inviting qualified bidders to submit bids for the project. A mandatory
contractor pre-bid meeting was held at the RIPS. Potential bidders were allowed inside the
facility to familiarize themselves with the site of the work and existing conditions. On
December 12th, 2019, five bids were received from contractors. The lowest, responsive and
responsible bid was submitted by Stellar J. Corporation from Woodland, WA. The bid amount is
$584,500. The Engineer’s estimate was $637,000.
RECOMMENDATION
Move to approve award of a public improvement contract to Stellar J. Corporation for Work
Order 290: River Intake Pump Station Upgrades, in the amount of $584,500 .
