CONTRACT CHANGE ORDER AGREEMENT
CAG-23-005 West Hill Booster Pump Station Improvement Project
WTR-27-04184
CONTRACTOR: Gary Harper Construction, Inc.
SUMMARY OF PROPOSED CHANGE:
Additional Pump Can and Pump Bay Excavation Requirement.
C.0.#1
The change order no. 1 is for the compensation for material, labor, and equipment costs for the contractor to
furnish and install three new pump bays, and pump cans to accommodate the new pumps to be installed as part
of the West Hill Booster Pump Station Improvements Project. The design plans for the project were developed
based on information from existing records of equipment in the pump station. After the removal of the existing
pumps, the contractor discovered that the three existing pump cans are shallower than anticipated. Three new
steel pump cans with longer lengths are needed to accommodate the installation of the longer bowls for the
new and larger pumps along with additional excavation and removal of soil materials under the existing pump
cans. The concrete bays supporting the pumps will need to be removed and replaced as part of the work.
Thirty (30) additional working days were approved for the additional work and lead time to get the new pump
cans and equipment. This change order will be paid as a lump sum.
ESTIMATED TOTAL CHANGE ORDER COST= $72,102.07
