2020
February
Please note that this project was repackaged into 3 distinct types of construction projects to encourage bidder participation. The packages and respective scopes as follow:
- Package 1 - Pipe Bursting: Hatfield Road to Orange Street
- Package 2 - Lift Stations and Mykawa Road Gravity Sewer. (This package also includes abandoning all gravity sewer mains along with the decommissioning of 3 existing lift stations along Mykawa Road)
- Package 3 - Force mains: Orange Street and Scott Street
Highlights:
Package 1 - Since the last Project Update the contractor, Nerie Construction, has completed the following:
- Contractor installed the remaining manhole at the intersection of Woody Street and West Orange Street.
- Site restoration is ongoing.
- Inner lining of existing sanitary sewer manholes has been coated with Sewper Coat.
- Completed CCTV inspection of existing sanitary sewer line along W. Orange Street and Hatfield Road.
- Cast iron frame and covers have been placed on all sewer clean-outs as specified in the City's construction details.
Nerie Construction officially submitted their letter of substantial completion dated February 3, 2020 for Package 1, approximately 20 days ahead of schedule.
Package 2 - Since the last Project Update the contractor, Black Castle, has completed the following:
- Received wet well risers for both proposed Orange-Mykawa and Scott-Mykawa Lift Sations.
- Implemented dewatering methods around both Lift Station locations due to shallow water tables.
- Constructed and installed the Orange-Mykawa Lift Station and the Scott-Mykawa Lift Station - wet well via Caisson-Method. Once the wet well was set at its permanent elevation, the contractor placed a seal-slab at the foundation to ensure that the inside of the well's surface remains dry and allows form work to take place for the proposed 2' wet well floor for both lift station bottoms.
- Black Castle's boring Sub, Nerie Construction, started boring preparations which consist excavating 2 pits, a sending pit and receiving pit at the intersection of Orange Street and Mykawa Road.
Enterprise Pipeline representatives suggested that the City adjust the vertical elevation of the proposed 12" sanitary sewer up and allow the Enterprise pipeline to remain under the City's sanitary sewer line.
Implementing this adjustment will not allow the City's sanitary sewer run to be shallower by approximately 9' to 10' depths on the downstream of the system and will also be a potential cost savings to the City of up to $90,000.00 while serving the same amount of area.
Package 3 - Since the last Project Update the contractor, Nerie Construction, has completed the following:
- Directional bored approximately 5,000 LF of 8" sanitary sewer force main at the following locations:
- Woody Street to Mykawa Intersection, along W. Orange Street
- SH35 to Scott Road (with the exception of the BNSF railroad crossing)
- Completed the proposed 200 LF jack and bore under the Orange-Mykawa Intersection.
- Installed 2 - 5-foot air release valve manholes.
During preparation of the proposed bore going under the BNSF Railroad, the railroad representative noted that the material on the approved permit issued by BNSF was different than what was noted on the construction drawings. This omission resulted in the contractor to be shut down until revisions to the permit are resubmitted and approved.
Upcoming Work Items:
Package 1 - Once the substantial walk-through takes place on February 12, 2020, the project will only begin to focus on closing the project and finish up any punch list items noted on the walk-throuhg.
Package 2 - In the upcoming weeks, Black Castle's sub-contractor, Nerie Construction, will continue to bore the proposed 12" sanitary sewer line from the Orange-Mykawa Lift Station, north towards Hickory Slough.
Black Castle will continue to work on building out the inside of both lift stations which includes the following:
- Complete form work for the 2' thick foundation floor
- Install the concrete fillets as shown in the construction details
Package 3 - Completion of Package 3 construction is dependent on the approval of the BNSF permit. Once the City has received the permit, the contractor will complete the bore under the railroad easement and afterwards will officially submit for substantial completion.
