Subject: INDIAN CANYON DRIVE AT VISTA CHINO TRAFFIC SIGNAL
MODIFICATION, CITY PROJECT NO. 08-17
From: David H. Ready, City Manager
Initiated by: Public Works and Engineering Department
SUMMARY
Approval of Contract Change Order No. 1 to Agreement No. 6093 with PTM General
Engineering Services is necessary to accommodate required changes in the work
related to the Indian Canyon Drive at Vista Chino Traffic Signal Modification, City
Project No. 08-17.
RECOMMENDATION:
1) Approve Change Order No. 1 to Agreement No. 6093 with PTM General
Engineering Services, in an amount of $27,354.83 for a revised total contract
amount of $230,557.83 for the Indian Canyon Drive at Vista Chino Traffic Signal
Modification, City Project No. 08-17; and
2) Authorize the City Manager to execute all necessary documents.
STAFF ANALYSIS:
On November 17, 2010, the City Council awarded a contract to PTM General
Engineering Services for modification and upgrade of the existing traffic signal at the
Indian Canyon Drive and Vista Chino intersection. Previously, the existing traffic signal
had no left-turn phasing in any direction, which made turning left difficult during peak
hours of traffic at this highly congested intersection. Vista Chino is also State Highway
111, and Caltrans operates and maintains this traffic signal.
Construction of this project has been under inspection by Caltrans, and during
construction Caltrans imposed certain requirements related to installation of underground
conduit and trench pavement repairs. These additional requirements were not originally
included in the project, and complying with these requirements incurred additional cost to
the contractor.
Item No. 2A .

depth of 30". The conduit placement as well as the placement of aggregate base and AC paving
of trenches was performed on a time and materials basis. The actual time and materials required
to complete the work was monitored and all applicable mark ups were applied to determine the
price of the work indicated above.
B. In accordance with State of California Requirements,the conduit trenches will be ground 18"
outside of trench edges and final paving cap will be placed. The lump sum price indicated above
was obtained by obtaining bids to complete the work. The low bidder was the originally listed
subcontractor and the price is inclusive of the allowable 5% mark up for work performed by a
subcontractor.
C. The cost for the originally specified installation method (which was not performed), is being
credited to the contract in the amount indicated above.
This is a final balancing change order. There are no other additional items of work on this contract.
