CITY OF SAN BERNARDINO - REQUEST FOR COUNCIL ACTION
STAFF REPORT
Subject:
Authorize the Director of Development Services to execute Contract Change Order No. One with
Guzman Construction Co. for the reconstruction of the Storm Drain and Catch Basin at Highland
A venue and "H" Street.
Background:
On October 13, 2008, a request for an informal bid was sent to Weka Inc., Nikola Construction
Corporation, and Guzman Construction. The informal bid request was to repair a box culvert at
Highland Avenue and "H" Street. Guzman Construction was the only contractor that responded
to the bid at a price of $24,000.00. On December 2,2008 a request for a P.O. was submitted and
construction followed thereafter.
Change Order:
During the repair of the box culvert the contractor encountered unforeseen conditions and
utilities as follows:
I. The existing soil was over-saturated and unsuitable for back fill. It was necessary to provide
new back fill material and haul away the saturated dirt. The cost of new dirt and time to haul
away the existing saturated dirt resulted in additional costs of $5,000.00.
2. During construction the contractor encountered an existing concrete roadbed that was not
known. To repair the box culvert it was necessary to remove the roadbed and dispose of the
concrete. The additional work was completed at a cost of $1 ,900.00
3. During construction the contractor encountered an old signal foundation that was in the path
of the proposed storm drain. It was necessary to remove the signal foundation and also the
existing sidewalk above the signal foundation. After the work was completed it was
necessary to replace the sidewalk. The cost to remove the signal foundation and replace the
sidewalk was $1,127.00.
Financial Impact:
The revised estimated project costs are as follows:
TOTAL
Original Contract Amount $24,000.00
Contract Change Order No. One $8,027.00
Total Proiect Cost $32.027.00
This change order represents a net increase of 34% of the contract amount. There are sufficient
funds in the account for the Change Order.
