Despite major advances in building materials and construction methods, water remains a formidable foe. Cracked, deteriorated masonry allows water to enter into a building, creating leaks that can eventually lead to structural damage. In cold weather, trapped water freezes and expands, causing bricks, stones, and other masonry to loosen, spall, and dislodge.

RAND has extensive experience in fighting leaks and deterioration through a carefully planned approach to maintenance and repair. Our engineering and architectural expertise covers the entire spectrum of exterior repairs and waterproofing, including:

Facade Inspection Safety Program (Local Law 11/98)

Under New York City's Facade Inspection Safety Program (formerly called Local Law 11/98), all buildings taller than six stories must be inspected by a Professional Engineer or Registered Architect every five years, and owners must file a facade condition report with the Department of Buildings. RAND’s in-house engineers and architects have issued more than 4,000 Local Law 10/80, 11/98, and FISP reports, and we have administered hundreds of follow-up repair programs. With our comprehensive knowledge of the laws' many details, we help building owners comply with the often complicated inspection, filing, and repair process to achieve a safe status for their properties.

Rope Access Facade Inspections and Evaluations

RAND has a team of certified Professional Rope Access Technicians who conduct facade inspections by rappelling down the sides of buildings. Rope access can be a more cost-effective and less intrusive way to evaluate facades compared to using a motorized scaffold. The advantages of rope access are faster mobilization, less disruption to tenants and residents, and cost savings for building owners.

RAND’s rope access team conducts FISP (Local Law 11/98) inspections, leakage investigations, emergency evaluations, curtain wall analysis, facade repair quantifications and evaluation, and more. 

Window and Door Replacement

Although one of the more costly and lengthy major capital improvement projects, window and door replacement programs can result in better thermal insulation, energy efficiency, and noise reduction, as well as an improved appearance to a building. Replacing window and doors requires careful consideration of several key issues, including the structural stability of the frame, water resistance, air infiltration, and noise abatement. For architecturally significant buildings, retaining the same design aesthetics, configurations, and sight lines is paramount. RAND has extensive experience with many types of window and door replacement projects, including double-hung, casements, sliding, projecting, and those for properties in historic districts.
