DESCRIPTION

This special provision contains the Division's estimate for force account items included in the Contract.

The estimated amounts marked with an asterisk will be added to the total bid to determine the amount of the performance and payment bonds. Force Account work shall be performed as directed by the Engineer.

The Force Account Work (labeled as Future Work in construction plans) on Harmony Road will encompass a series of planned infrastructure improvements. These include the extension of the CR-15 Trail to establish connectivity with the existing pedestrian sidewalk north of Harmony Road, installation of a reinforced structural headwall designed to interface with the existing box culvert conveying stormwater beneath Harmony, placement of a code-compliant safety handrail, relocation of one signal pole on the SW corner, Harmony Road median modifications and execution of all associated grading operations to ensure proper drainage and structural stability.

Payment will be made in accordance with subsection 109.04. Payment will constitute full compensation for all work necessary to complete the item.

Force account work valued at $5,000 or less, that must be performed by a licensed journeyman in order to comply with federal, state, or local codes, may be paid for after receipt of an itemized statement endorsed by the Contractor.

Force Account Work on Harmony Road will be quantified and presented to the contractor so that unit costs can be negotiated for the work. It is the town’s intent to utilize agreed upon unit costs to compensate the contractor instead of using the force account methodology to pay for this work.
