You are authorized and directed to make the described changes from the plans and specifications, or to
increase or decrease contract quantities, as follows:
During the dewatering operations, additional groundwater was observed entering the stilling basin from drains
that were uncovered under the silt levels at the bottom of the spillway. After the dewatering operations were
completed, 4” rubber drain plugs were installed at the uncovered spill way drains to allow dredging operations
to start and continue with the skid-steer and a small trash pump. All labor, rental equipment, and installed
materials were recorded under a force-account and the contractor was directed to continue per the
requirements of the plans and specifications.
The contractor is directed to provide credit for Bid Item #6 for the Temporary Dam and Piping system required
to drain the stilling basin and provide additional dewatering systems to inspect the six spillway drains
uncovered under the silt deposits.
The work includes additional equipment rental for a storm pump, piping connections to a lay-flat hose, and
erosion control measures per the contract plans and specifications. MidCal Dredging has submitted a total
cost of $89,101.68 for this scope, which includes all labor and materials and a credit of $39,691.00 from the
original contract, which totals a contract change order of $49,410.68.
Staff supports this directive, as it is within the existing project area and represents a cost -effective
enhancement to the contract.
All labor, equipment, and material will be paid at the Lump Sum price submitted by MidCal Dredging as
