STAFF REPORT
Subject:
Authorize the Director of Development Services to execute Contract Change Order No. One with
El-Co Contractors, Inc. for Sanitary Sewer Improvement Relocations for State Route 210,
Segment 11 (SW09-03), Per Project Plan No. 12517.
Background:
In March of 2009, the California Department of Transportation (Caltrans) and the City of San
Bernardino entered into a utility agreement as part of the realignment and widening of the 1-210
Freeway. The agreement, which required Caltrans to reimburse the City for all engineering,
inspection and construction costs associated with the relocation of conflicting sewer facilities
within Segment No. 11, was approved by the Mayor and Common Council on March 16, 2009.
The sewer relocation project involved the Segment No. 11 1-21011-215 Interchange
Improvements, which included sewer relocations at 27h Street and a portion of Little Mountain
Drive. Under the utility relocation agreement, Caltrans agreed to reimburse the City for all costs
associated with the relocation of conflicting sewers related to the Segment 11 I-210/1-215
Interchange Freeway Improvements up to and amount of$412,500.
On July 6, 2009, the Mayor and Common Council approved the award of a contract to El-Co
Contractors, Inc. for Sanitary Sewer Improvement Relocations for the I-210 Freeway Widening,
Segment 11 (SW09-03), per Project Plan No. 12517.
Construction Change Order No. One:
During construction, the contractor discovered that the existing sewer line location differed from
the one shown on the approved plans by Caltrans, causing delays and re-design work. In
addition, relocations of an undocumented conflicting utility, and siphoning of an existing water
line were included in the project as part of the changes and approved by Caltrans. This
additional work was not included in the contractor's original bid. The descriptions and
justification of these items are detailed in the attached copy of Contract Change Order No. One.
Financial Impact:
The revised estimated project costs are as follows:
TOTAL
Original Contract Amount $ 195,033.00
Adjustment due to Reduced/Deleted Items $28,918.00
Contract Change Order No. One $ 105 080.89
Total Construction Contract Amount $ 271,195.89

STAFF REPORT—Continued
This change order represents a net increase of 53.9% of the original contract amount. There are
sufficient funds in the project account to cover this change order. The change order exceeds the
10% contingency, but the actual inspection costs were less than estimated in the original design
phase, so no additional funds are needed for this project. In addition, the City will be
reimbursed 100% of the final construction cost including change orders from Caltrans. The
project was recently completed.
Account Budgeted Amount: $ 3,012,100. Balance as of: 03/05/2010.
Balance after approval of this item: $2.907.019.
Please note this balance does not indicate available funding. It does not include non-encumbered
reoccurring expenses or expenses incurred but not yet processed.
Recommendation:

SANITARY SEWER IMPROVEMENT RELOCATIONS FOR STATE ROUTE 210,SEGMENT 11(SW09-03),PER PROJECT PLAN NO.12517
JUSTIFICATION:
Extra Mobilization Due to Delay
Item During construction, it was discovered that the existing sewer line location in the field
Item differed from the one shown on the approved plans. With that, the Contractor had to
de-mobilize and re-mobilize their operation due to the time necessary for the design
engineer to alter the proposed sewer alignment per the field condition.
Additional Video&Manhole Exploratory Work
The contractor was directed to video additional existing sewer line and manhole
1-2 exploratory work, due to the new alignment. This additional work was not
included in the original contract bid item.
Additional Sewer Main and Sewer Concrete Encasement
Item 1-1 required the contractor to perform additional survey services since the
alignment and elevations differed from the ones shown on the approved plans;
therefore, the contractor was required to construct the proposed sewer line at the new
1-3 proposed alignment and elevations accordingly. In addition,the contractor was required
to construct 100 additional lineal feet of 8" sewer main along with 48 additional lineal
feet of concrete encasement. Three (3) pine trees and stumps were in the way in the
new sewer alignment that needed to be removed and disposed of This additional work
was not on
nally anticipated and was not included in the original contract bid item.
Remove and Replace Storm Drain Line and Sewer Concrete Encasement
During construction, it was discovered that the existing 16" storm drain line was in
1-4 conflict with the proposed sewer line in the dike's vicinity along 27th Street; therefore,
the contractor was directed to remove the existing Storm drain and replace it after the
encasement of the 181 lineal feet of the existing sewer line. This additional work was
not included in the original contract bid item.
Extra Work on 2 Sewer Manholes
1-5 During construction it was determined that the contractor was required to modify two
existing manholes of the sewer line. This additional work was not originally included in
the original contract bid item.
Additions Done on Time and Material and Equipment Basis on August 26-27,
September 8-10 and 24
1-6 The contractor was directed to perform exploration work for the existing sewer main,
buried manholes, and an unmarked water line for the design engineer between the
period August 26 and September 24 on time and material basis. This additional work
was not originally anticipated and was not included in the original contract bid item.
Additional Work Done to Siphon Water Main on 27' Street
During construction, it was discovered that there was a conflict between the proposed
sewer main and existing water main along 27' Street,which was not shown correctly on
1-7 the approved plans; therefore, it was necessary for the contractor to siphon the water
main in order for the contractor to construct the proposed sewer main per the approved
plans. This additional work was not originally anticipated and was not included in the
original contract bid item.
Additions Done on Time and Material and Equipment Basis on Asphalt Concrete
Pavine
1-8 During construction, it was discovered that the contractor was required to perform
additional asphalt concrete paving beyond and above the original contract bid item (up
to 125%); therefore, it was necessary for the contractor to complete the said paving
work on a time and material basis.
