Subject: PALM SPRINGS STORM DRAIN LINE 6A, LINE 8, LATERAL 20C AND
LATERAL 20CA PROJECT, CITY PROJECT 05-20
From: David H. Ready, City Manager
Initiated by: Public Works and Engineering Department
SUMMARY
During construction of the major storm drain project, currently underway, it was
necessary to perform additional design work to ensure continued progress with the
project. Approval of Contract Change Order No. 4 to the consultant's agreement will
compensate the consultant for work performed.
RECOMMENDATION:
1) Approve Amendment No. Four (4) to Agreement No. 5275 with Engineering
Resources of Southern California, Inc., in the amount of $31,165 for a total
revised contract amount of $683,170 for the Palm Springs Storm Drain Line 6A
and Line 8, City Project No. 05-20; and
2) Authorize the City Manager to execute all necessary documents.
STAFF ANALYSIS:
On July 16, 2008, City Council awarded a construction contract to Ken Thompson, Inc.,
for construction of Palm Springs Storm Drain Lines 6A and 8. This project has been
underway since October 2008, and has made significant progress to date. The original
plans required construction of large cast-in-place reinforced concrete box culverts (12
feet high by 8 feet wide, and 8 feet high by 5 feet high) within Sunrise Way. The
logistics of constructing cast-in-place structures involves forming the bottom first,
pouring concrete and allowing it to sufficiently cure; forming the sides second, pouring
concrete and allowing it to sufficiently cure; and forming the top last, pouring concrete
and allowing it to sufficiently cure prior to backfilling and paving the trench. Cast-in-
place construction is labor intensive and time consuming.

Storm Drain Projects (CP 05-20)
The storm drain improvements, once completed, will be owned and maintained by
Riverside County Flood Control District (RCFC). Prior to starting the work, staff
coordinated with RCFC to determine their willingness to allow installation of pre-cast
reinforced concrete box culverts in lieu of cast-in-place structures. Initially, RCFC
denied the request, as there is no "standard" for pre-cast concrete box structures they
have accepted. However, through cooperative efforts, and the assistance of the City's
design consultant, RCFC reconsidered and allowed this project to serve as a test-case
for installation of pre-cast concrete box structures.
Additionally, during construction certain opportunities occurred where value engineering
of the approved design would result in cost savings, and changes to the alignment
would decrease impacts to traffic during construction- Staff coordinated with the City's
design consultant to prepare revised construction drawings to facilitate certain value-
engineered components of the project, and to revise alignments to decrease disruptions
to traffic during construction-
Staff and the City's consultant have worked diligently during construction of this project
to ensure progress has not been delayed, and coordinated ways to speed up the project
at every opportunity. Staff recommends that the attached contract amendment be
approved to compensate the City's consultant for services provided during construction
that have enabled this project to progress more quickly, and in some cases, resulted in
cost savings to the City.
The overall construction phase of the consultant's contract, including Amendment No. 4,
is $321,725 which represents 6.3% of the construction contract amount of $5,087,598;
typical construction inspection/administration costs are equivalent to 15% of
construction costs. The consultant's fees for construction phase support are very
competitive and reasonable.
FISCAL IMPACT:
Sufficient funding is available in account 135-4371-55006. This project has been
funded entirely with drainage fund revenues; no miscellaneous General Fund revenue
has been used for this project-
