RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute Contract Change Order No. 1 (CCO #1) to the contract with GradeTech, Inc., and Hess Concrete Construction Co., Inc., to change the not-to-exceed contract amount from $400,000 to $700,000 each for the On-Call Contract(s) for Various Road and Flood Control Maintenance Work, Countywide.

FISCAL IMPACT:

CCO #1 will increase the not-to-exceed amount for each contract from $400,000 to $700,000. This work is funded by Local Road and Flood Control funds.

BACKGROUND:

On March 15, 2016, the County awarded two on-call contract(s) for various road and flood control maintenance work to supplement the maintenance crews' routine and emergency work, for a total allotted amount of $800,000, in the following priority order:

BACKGROUND: (CONT'D)

GradeTech, Inc., in a not-to-exceed amount ($400,000) and the unit prices submitted in the bid ($1,254.51 Total Unit Price);

Hess Concrete Construction Co., Inc., in a not-to-exceed amount ($400,000) and the unit prices submitted in the bid ($1,511.50 Total Unit Price);

The on-call contracts became effective on March 15, 2016 and expire March 15, 2017.

In February 2016, a sink hole developed on Hazel Avenue between Ralston Avenue and Sonoma Street in the East Richmond Heights area. The sink hole developed due to the deterioration of an aging corrugated metal storm drain pipe under the road. To accommodate the unforeseen emergency storm drain repair work on Hazel Avenue, it is necessary to increase the not-to-exceed amount of GradeTech, Inc.'s contract from $400,000 (as awarded) to $700,000. CCO #1 has been prepared to cover the proposed increase and to authorize payment for road and flood control maintenance work performed on or after June 1, 2016 for both GradeTech, Inc. and Hess Concrete Construction Co., Inc.

To enable timely payment to GradeTech, Inc., and Hess Concrete Construction Co., Inc., the Public Works Director recommends that the Board approve CCO #1 and authorize the Public Works Director, or designee, to sign it for the County. The increased contract amount for GradeTech, Inc., and Hess Concrete Construction Co., Inc., will increase the total allotted amount for road and flood control maintenance work to $1,400,000.

CONSEQUENCE OF NEGATIVE ACTION:

These contracts have a term of one year and once the available contract capacity is used, there is no remaining contract capacity for on-call routine and emergency work for the remainder of the term. Failure to approve CCO #1 would prevent the Public Works Department from completing routine and emergency road and flood control maintenance work in a timely manner and preclude payment to GradeTech, Inc. and Hess Concrete Construction Co., Inc. for compensation due to them for completing road and flood control maintenance work.
