CITY OF SAN BERNARDINO - REQUEST FOR COUNCIL ACTION
Staff Report
Subiect:
Authorization to execute Change Order No. One to contract with Fibrwrap Construction, Inc. for seismic
retrofit and repair of City's five-level parking structure, per Plan No. I0304-A.
Backt!round:
Bids for seismic retrofit and repair of City's five-level parking structure, per Plan No. I0304-A were
received on May 28, 2002, and a contract in the amount of $1,146,000.00 was awarded to the lowest
bidder, Fibrwrap Corporation, on August 5, 2002.
While preparing the expansion joint on level 2 between grid A and grid B (westerly bay) for replacement
as required by the plans, the Contractor found a crack approximately 8 feet long paralleling the joint. The
crack appears to be the result of deterioration from age and water intrusion into the concrete together with
the effect of repetitive traffic loading. The structure has been in service for approximately 28 years.
Staff reviewed the crack with representatives of the project Structural Engineering firm, T. Y. Lin
International, and concluded that the crack can be repaired with epoxy; however, in order to make the slab
structurally safe for traffic, it will be necessary to install an additional steel bent plate support below the
slab.
Steel bent plate supports were initially deemed to be required only under the slab at the joints on levels 3,
4 and 5 during design. Based on examination of plans of the existing structure, the consultant Structural
Engineers concluded that the steel bent support was not needed on level 2 because the existing joint gap
appeared to meet seismic separation requirements. However, field inspection clearly confirmed the need
for the steel bent plate support under level 2 as well.
The Contractor has submitted a cost proposal in the amount of $459.23 to perform an epoxy repair ofthe
8 foot long crack in the slab on level 2. The Contractor has also submitted a proposal to supply and
install the additional steel bent plate supports under the slab of level 2. The cost of the work is
$27,858.70 for a total change order amount of $28,317.93. We feel the costs submitted by the Contractor
are reasonable for the proposed work. Copies of the Contractor's proposals are attached to the attached
Change Order No. One.
The details of this change order are described in the attached Change Order No. One.
Financial Impact:
Total funding needs for this project in the amount of $1,800,000.00 were allocated from various City and
EDA funding sources by actions of the Mayor and Common and the Community Development
Commission at the regular meeting of August 5, 2002. Sufficient funds are available to cover the cost of
this change order in the $110,000.00 contingency account which was authorized by the Mayor and
Common Council as part ofthe contract award.
