Subject: A) Consideration of Contract Change Order No. 1 to the contract with Argonaut Constructors, Inc. for the 2024 Pavement Rehabilitation Project for a decrease of $449,232.30; and

Executive Summary:
On July 29, 2025, your Board directed staff to proceed with modifying the construction contract with Argonaut Constructors, Inc. for the 2024 Pavement Rehabilitation Project in Cobb. That direction was to surface with asphalt concrete certain roads that had been pulverized and chip sealed in the original contract scope of work. To that end, attached for your Board's review and approval is Contract Change Order (CCO) No. 1 and CCO No. 2.
CCO No. 1 addresses the deletion of unused contract quantities for pulverization, double chip seal, hot mix asphalt (HMA), and asphalt concrete (AC) dike, as well as increased digout (i.e. road repair) quantity costs. The net decrease for CCO No. 1 is $449,232.30.
CCO No. 2 addresses additional contract quantities and costs for mobilization, traffic control, utility adjustments, HMA, and aggregate base; a reduced contract price for chip seal; and an added contract item for road preparation. Additionally, this change order adds fifteen working days to the contract. The net increase for CCO No. 2 is $1,477,626.93.
The two CCO's result in a total contract increase of $1,028,394.63, for a revised contract amount of $6,142,091.38.
The contract change will be paid using Road Maintenance and Rehabilitation Account apportionments and $225,000 of cannabis discretionary funding. There are sufficient capital appropriations in Budget Unit 3011, Roads.
