Agenda Item
Discuss, consider, and take appropriate action regarding Change Order no. 1 in the amount of $139,570.57 for 2138 CR 101 (James Construction), a Road Bond project in Commissioner Pct. 4.  P: 269 Funding Source: Road Bond.
This Change Order adds various changes to the project, including additional pipe underdrains to help alleviate groundwater, concrete used to backfill Culvert 4, and the use of full depth asphalt on side roads and intersections to expedite the reconstruction of the intersections.
Item 341-WC03 Full Depth HMAC was utilized to expedite the work at the CR 394/368, CR 160, CR 369, and CR 395 intersections with CR 101. These intersections were to be constructed with lime-treated subgrade and flexible base, while maintaining traffic access. Use of full-depth hot mix decreased the time for the work from approximately two (2) weeks to one (1) day at each intersection.
Item 401-6001 Concrete Backfill was used to backfill Culvert 4 because the top of the pipe protruded into the limits of the lime-treated subgrade. The Contractor had to place and remove formwork to construct the backfill. The concrete backfill will protect the pipe during the construction of the roadway pavement section. 
Item 556-WC01 Underdrain was for additional pipe that was needed to capture groundwater encountered while making subgrade for the roadway from stations 110+20 to 113+78, east of the existing roadway. The groundwater in this area was not allowing the subgrade to dry out enough to make a solid subgrade. Underdrain envelope rock sized at 3” x 5” rock was used, instead of the half inch gravel. This will provide a solid foundation for the roadway in this area.
