Northampton, MA 01060 po �d * " Re: 64 Hawley Street fovo� Northampton, MA 01060 Louis: On July 17, 2012, 1 visited the above address at the request of Mr. Michael Pancione from Pancione Associates Regional Realty, LLC. Mike informed me that he would be making some foundation repairs to the top of a foundation wall located under a gable wall at the north side of this structure. The structure at the above address is a four unit R-2 use group apartment house. The cubic area of this structure is likely over 30,000 cubic feet and will require controlled construction reports while the proposed foundation repairs are being made. The foundation wall that Mike intends to repair consists of a multi-wyth brick foundation wall from the existing wood sill above to slightly below grade. This brick wall cap bears upon a dry- stacked stone foundation wall that starts slightly below grade and ends at an unknown depth below grade. The wall to be repaired is located at a small crawl space that juts off of a full basement. The repair is being made because the existing wall to be repaired has bowed inwards at the brick and field stone interface located slightly below grade. The brick foundation wall cap, nor the dry stacked foundation wall below is no longer plumb. Mike intends to install temporary needle beams to support the existing main floor and gable wall above the foundation wall in question. This will allow him to rebuild and repair the foundation as n:quired to return this foundation wall to a plumb location beneath the wall above. Mike asked me to design a new main floor dropped beam to install near the tbundatior, Nvall, repair location. There is currently a wood dropped beam that supports the main floor joists at the fidil basement/crawlspace location. This wood beam is supported by masonry counterforts at the beam ends and a wood column at the beam mid-span. The existing foundation supports belwo the existing dropped wood beam does not look to be in great condition. A new main floor steel beam will be installed south of the existing wood beam. This new beam will support the same joists as the existing wood beam. The existing beam and the new beam will only support a small area of the main floor and does not support and additional load from above. 8 Coates Ave.,South Deerfield,NIA 01373 W (413)665-4018 W fax(413)665-1142 W thayerstreetassociates.com
