STAFF REPORT
Page 1 of 2
During the first stages of construction, the Contractor
discovered two errors in the construction drawings prepared by
the Consulting Engineer.
One was a one-half foot error in the elevation differ-
ence between the third floor of the City Hall Annex (Thrifty
Building) and the Five-Level Parking Structure. The plans do
not reflect the survey measurements provided by the City. As a
result, the pedestrian ramp must be extended by eleven feet, in
order to comply with the State of California I s Title 24 re-
quirements for handicap access. The cost to perform this extra
work is $4,576.11.
The second problem was the result of the Consultant
using the structural framing plan from the second floor of the
City Hall Annex rather than the third floor. Therefore, the
project drawings did not include the stiffener plates necessary
to increase the load carrying capacity of the existing steel
beam to handle the additional load imposed by the pedestrian
bridge. The cost to add the beam stiffener is $2,730.42.
Due to the changes to the ramp and the structure, the
structural steel shop drawings, the rebar shop drawings, the
handrail shop drawings and the beam stiffener plate shop
drawings must be revised. The cost to revise the shop drawings
by the Subcontractor is $1,767.15.
During the drilling of the bridge caissons, an unmarked
3" irrigation line was encountered. The Contractor removed the
interfering portion of the line and capped off the remaining
line. The cost to perform this work was $277.00.
Change Order No. One authorizes the Contractor to
lengthen the pedestrian ramp an additional 11 feet, install
stiffener plates to the existing beam within the Annex Building
and revise the shop drawings. The removal of the irrigation
line is also authorized. The total estimated cost of Change
Order No. One is $9,350.68, which will increase the contract
price from $116,000 to $125,350.68.
An amount of $6,900 was included in the total estimated
project cost for contingencies, which can be used to finance the
cost for this extra work. The remainder of the cost for
Contract Change Order No. One can be financed from the available
balances for other items of renovation work to be financed from
the total available amount of $600,000.
