ENGINEERING DIVISION CONSTRUCTION CONTRACT NO: 18-050
PROJECT: Mission Avenue Improvement Project CONTRACT DATE: 5/31/2018
PRIME CONTRACTOR: MDM Construction,Inc. CIP NO: 123
DESCRIPTION OF CHANGES
The project design calls for a 12'diameter PVC storm drain line(P-31)'on the north side of Mission Avenue to cross under a
6 inch diameter Consolidated Irrigation District 19(CID 19)6 inch diameter Asbestos Concrete waterline running on the west
side of Greenacres Road on the west side of the Mission Avenue/Greenacres intersection. The storm water design
assumed the waterline was installed with 4 foot of cover and the 6 foot deep storm waterline would pass underneath. The
waterline,constructed in 1967 had 6 feet of cover, resulting in a conflict. CID 19 has prior rights and did not wish to
reconfigure the waterline.
This change order revises the stormwater piping and grades to pass over the CiD 19 waterline. It also pays, per force
account for the work involved to remove the installed pipe P-30, reset SDMH-1 and core in a new western inlet at the revised
invert elevation.
