RECOMMENDATION(S):

APPROVE and AUTHORIZE the Interim Public Works Director, or designee, to execute Contract Change Order No. 1 (CCO #1) with GradeTech, Inc., and Hess Concrete Construction Co., Inc., to increase the payment limit from $500,000 to $1,000,000 each, and to extend the completion dates for each contract from December 6, 2017 to December 6, 2018, for the 2017 On-Call Contract(s) for Various Road, Flood Control, and Airport Maintenance Work, Countywide.

FISCAL IMPACT:

100% Local Road, Flood Control District and Airport Funds.

BACKGROUND:

On December 6, 2016, the County awarded on-call contract(s) for various road, flood control, and airport maintenance work to supplement the maintenance crews’ routine and emergency work, for a total allotted amount of $1,000,000, in the following priority order:

GradeTech, Inc., in a not-to-exceed amount ($500,000) and unit prices submitted in the bid ($1,193.00 Total Unit Price);

Hess Concrete Construction Co., Inc., in a not-to-exceed amount ($500,000) and unit prices submitted in the bid ($1,484.00 Total Unit Price);

The on-call contracts became effective on December 6, 2016, and expires on December 6, 2017.

Due to the large amount of unforeseen infrastructure damage caused by last winter’s storms and the resulting maintenance backlog, the existing payment limit for these contracts is close to being exceeded. It is necessary to increase the contract payment limit for GradeTech, Inc.’s and Hess Concrete Construction Co., Inc.’s, from $500,000 to $1,000,000 each. CCO #1 has been prepared to cover the proposed increases and to authorize payment for road, flood control, and airport maintenance work performed on or after September 15, 2017. The Public Works Department is requesting the contract values be increased and the term extended to December 6, 2018 to accommodate the maintenance backlog.

To enable timely payment to GradeTech, Inc., and Hess Concrete Construction Co., Inc., the Interim Public Works Director recommends that the Board approve CCO #1 and authorize the Interim 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, flood control, and airport maintenance work to $2,000,000.

CONSEQUENCE OF NEGATIVE ACTION:

These contracts have a term of one year (with the option of two one-year extensions) 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 road, flood control, and airport 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, flood control and airport maintenance work.
