RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute Contract Change Order No. 1 with GradeTech, Inc., effective June 21, 2022, to increase the contract limit by $57,466.08, to a new payment limit of $169,454.08, for the Ygnacio Valley Parking Lot & ADA Improvements Project (WONX40608), Walnut Creek area.

FISCAL IMPACT:

The total estimated construction cost will be funded by 85% Community Development Block Grant (CDBG) and 15% Library Department.

CONSEQUENCE OF NEGATIVE ACTION:

Without approval, the contractor will not be able to successfully complete this contract and receive payment for the additional work performed.

BACKGROUND:

Contract Change Order No. 1, is necessary to pay the contractor, GradeTech, Inc., for the following items: Labor, materials, equipment, and supervision for additional 158 SF of concrete curb and sidewalk removal plus 315 LF of new minor concrete work in the amount of $32,917.50 and to raise storm drain inlet approximately 9” at added curb replacement to allow for ADA parking grades in the amount of $6,596.88. In addition, due to rise in cost of oil from time of bid, Contractor is allowed compensation for additional cost of Hot Mix Asphalt in the amount of $17,951.70.

Change Order No. 1 will increase the original contract limit from $111,988 to a new payment limit of $169,454.08 and is well below the engineer's construction cost estimate of $260,000.
