Agenda Item
Discuss, consider, and take appropriate action regarding Change Order No. 4 in the amount of ($366,519.81) for 2138 CR 101 (James Construction), a Road Bond project in Commissioner Pct. 4. Project: 269 Funding Source: Road Bond.
Background
This Change Order adds a force account item to the Contract to compensate the contractor for pavement repairs in the roadway and to perform grading to prevent future saturation. This Change Order also removes quantities for various Jonah Water SUD water line items, due to an alignment shift at the southern end of the project at the US 79 intersection.
Item 999-WC01 Force Account-Roadway Repairs and Grading on North End is being added to pay the contractor for pavement repairs and to perform grading.
Pavement repairs are necessary, due to recent rains that created an area of ponding water adjacent to the roadway. The standing water migrated into the roadway embankment and saturated the subgrade. This caused a failure in the new roadway at the north end of the project. The repair will consist of:
In addition to the pavement repair, the contractor will regrade the area to prevent water from ponding next to the roadway again. Tracking the contractor’s actual cost by force account is the best method to determine the cost of the work, because some elements of the work are unknown at this time.
The original Jonah Water relocation plans show relocations that were necessary for the proposed CR 101 alignment that was revised and moved further north. This change made the original Jonah Water relocation length of pipe and appurtenances shown on the attached sheets no longer necessary.
Item 999-WC01 Force Account-Roadway Repairs and Grading on North End is being added to pay the contractor for pavement repairs and to perform grading.
Pavement repairs are necessary, due to recent rains that created an area of ponding water adjacent to the roadway. The standing water migrated into the roadway embankment and saturated the subgrade. This caused a failure in the new roadway at the north end of the project. The repair will consist of:
- Excavating approximately 5’ below the current finished grade of the roadway to remove wet material. Actual depth of excavation will be determined based on moisture content of material encountered.
- Placing large rock in the bottom of the excavation to establish a good foundation.
- Place embankment material with low clay content or flexible base to level with original pavement section.
- To expedite construction, full-depth hot mix asphalt will be considered in lieu of flexible base.
In addition to the pavement repair, the contractor will regrade the area to prevent water from ponding next to the roadway again. Tracking the contractor’s actual cost by force account is the best method to determine the cost of the work, because some elements of the work are unknown at this time.
