  • 6-13-18 - Excavation work continues, storm sewer pipe has arrived on-site, and A&B hopes to transfer a sanitary force main over to a new pipe that will be out of the immediate area of the new head-wall.  A&B hoped to transfer over the sanitary force main to get it away from where the new retaining wall will be located.  MSD Maintenance had difficulty in finding the pump station for that main, so this transfer is planned for tomorrow morning.
  • 6-14-18 - A&B got the north manhRott Pipeole structure dug down to grade.  The force main relocation was completed this morning.  They also plan to set the new north manhole today.  New retaining wall block was received this morning as well as new storm sewer structures for this project.
  • 6-15-18 - A&B is having to remove rock from the bottom of the north structure in order to get the bottom of the new structure down to grade.  There is a steady stream of water coming from above too that required de-watering.  The plan today is to get the north structure set so material and be removed to run new pipe before commencing with old wall removal and placement of new retaining wall. 
  • 6-18-18 - A&B has the north structure set.  They removed rock for this on Friday until about 2pm.  Today the plan to de-water the upstream hole, dig out the pipe crossing below the road and set the new pipe.  The old wall still requires removal.  Rain is predicted in the area from Wednesday through the weekend.  A&B would love to have the new pipe in place before the rains come.
