Foundation and structural repair cost

[Dhru Das]

hello I am looking to purchase a 2 unit frame building in Chicago with full basement. The building has visible water seepage along with some brick foundation cracks. Also floor on all 3 floors are uneven.Following is recommended action as per the structural engineer. Anyone done similar kind of work and any idea on approximate cost? OBSERVATIONS AND RECOMMENDATIONS This  house  structural  system  needs  rehabilitation  including  existing  floor  joists  strengthening  by  adding  new members or replacing with new joists.  Roof  Rafters  need  to  be  strengthened.  The  basement  need  a  drain  tile  system  with  new  sump  pumps  for  proper drainage. Also existing brick foundation  wall need  to be tuckpointed and waterproofed. The  existing  roof  structural  framing  will  need  to  be  strengthened  by  adding  new  wood  rafters  of  appropriate  size and any existing roof rafters  found deteriorated will  be replaced or  strengthened. Here is a  brief summary of  proposed structural work:      The building  basement  perimeter  (inside)  will  need  to  be  dug  and  new  drain  tile  will  be  installed  along  with brick  foundation  wall  tuckpointing  and  water  proofing.  A  new  sum  pump  system  will  be  installed  and connected  to  main  storm  sewer  system  for  proper  drainage.  Similarly,  the  existing  exterior  front  walls  will be strengthened as required  and will not be removed.    All  floor  framing  will  be  evaluated  after  the  existing  ceiling  is  removed  and  will  be  removed,  replaced  or strengthened  as required. Specifically the first floor framing  through out  the building due to  uneven floors in the front and  cur joists in the  utility room. Existing roof framing need to be strengthened as the existing roof rafters are inadequate.
