| BACKGROUND: |
Meeting in regular session on August 16, 2018, the Board awarded Contract PD 17-18.048 - East Carver Park Drainage Improvement Project to B&W Utilities, Inc. The project consists of installing a new stormwater conveyance system along Washington Street, Lincoln Street, Webb Street, Griggs Street, and Ransom Street. The new system will outfall to a new stormwater pond located east of Ransom Street. Work includes but is not limited to construction of shallow roadside swales, ditch bottom, and curb inlets, approximately 4,900 LF of reinforced concrete and polyethylene stormwater transmission pipes, and a single dry detention pond. The project also includes the relocation/installation of approximately 1,900 LF of 4” and 6” PVC water main and appurtenances, segments of full depth roadway reconstruction, milling and overlay of affected area roadways, and final site dressing and restoration.
Change Order #1, in the amount of $68,778.11, provided funding for the removal and replacement of additional asphalt roadway, base, and curbing necessary to install a proposed 60" stormwater pipe 15' deep under the roadway, upsize of an 18" pipe to a 24" pipe and a 24" pipe to a 36" pipe to accommodate additional stormwater coming off of Highway 297, modification of structures and pipe required to change the alignment of the pipes running through the park to decrease impact to the existing heritage oaks, installation of a swale through the park to channel stormwater to the new conveyance system, installation of a berm around the south side of the pond top to help channel stormwater to the outfall ditch, installation of a 6" concrete weir wall within Structure S-65 and a concrete flume with a splash pad and rip rap in the pond to prevent erosion and backflow from the outfall ditch, and the additional liability insurance premium required to meet minimum insurance requirements specified by International Paper.
Change Order #2, in the amount of $34,913.41, was for a full reconstruction (in lieu of milling and resurfacing) of the roadway on a section of Washington Street due to the depth of the proposed adjacent stormwater pipe. The proposed pipe is 8' deep and is close to the roadway. As the contractors dig to install the pipe, they are losing portions of the roadway. Also, additional quantities for waterline work were required due to the proposed water line being in conflict with the proposed stormwater pipe on Webb Street.
This Change Order, #3, in the amount of $48,232.68, adds funding for additional dewatering work required to install the proposed stormwater pipe per plan, required because the contractor’s original bid on dewatering was based on a geotechnical report from 2014 which stated that perched groundwater only may be encountered at a depth of 10’ or less. The proposed stormwater pipe being installed is at a depth of 16’ and the contractor is encountering groundwater from the groundwater table, not perched groundwater. The county ordered a new geotechnical report which confirms that the contractor is in fact in the groundwater table.
