Working with the architect, SGH helped develop a rehabilitation plan for the building enclosure and consulted on the building enclosure design. Highlights of our work include the following:

• Visited the site to document the condition of the building enclosure, including roofing and exterior brick masonry walls clad with cement plaster
• Provided recommendations to improve the building enclosure’s performance
• Developed procedures for monitoring cracking in the cement plaster walls during structural repairs
• Prepared construction documents for replacing the low-slope roofing and installing new clay tile roofing
• Reviewed the proposed design for waterproofing at existing loggia and balcony areas, and for flashing at new and rehabilitated windows
• Provided construction administration services, including reviewing contractor submittals, observing ongoing construction to compare with the project requirements, and helping the contractor resolve unforeseen field conditions
