  • 6-12-18 - Rott Rd. is closed.  Above & Below (A&B) is on site and starting construction activity in the work zone.  A&B is hand digging to expose known utilities in the area.  This process is known in the construction trade as "potholing."  They are doing this before commencing with larger scale excavation work involved to replace the retaining walls and storm sewer piping.
  • 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.
  • 6-19-18 - A&B continues with pipe installation in hopes of beating the forecast rains.  They continue to encounter bedrock with pipe installation.  They are about 1/2 way across the street moving toward the old rock wall as of 8am this morning.
  • 6-20-18 - A&B is on-site performing clean up work.  They might start removing some of the old wall in preparation for the new wall.  They have 2 more sections of pipe to set.
  • 6-21-18 - A&B is removing what's left of the old retaining wall today and starting to excavate for placement of the new retaining wall.  Ameren completed their power relocation work in the area.
  • 6-22-18 - A&B is on-site.  They are de-watering and hope to set the last sections of pipe and excavate to start setting wall sections. A&B was not able to set pipe or wall for the rock that was encountered.  The rains in the afternoon cause the water main  in the are to break.Block Wall

  • 7-6-18 - It was determined that the reset pole by Ameren needed to go about another 5' east that the location where it was set.  We're not sure when Ameren can mobilize to correct this matter, but it will impede the progress of this wall installation.  A&B will be moving blocks and digging the west wall down to grade.  They say they can set some of the bottom block and new pipe for this Headwall even with the power pole conflict.  They are also water jetting the fill area of the East wall and placing wall cap blocks on this structure.
