Our multidisciplinary expertise was applied to carry out the investigation, design and field review of the building envelope upgrade.  Rehabilitation was based on a condition assessment of the building and included several recommendations and cost estimates for repairs.  Rehabilitation consisted of replacement of existing windows with improved membrane and metal flashing details, replacement of rotten wood elements and removal and replacement of cladding  to improve waterproofing details in the wall assembly.  We also provided litigation support services, building envelope assessment, building science design services, preparation of tender drawings and specifications, construction administration, and construction review services to help the client complete a successful rehabilitation process from start to finish.
