We've worked on all types of enclosures from modern curtain walls and mid-century hybrid construction to prewar composite walls and ornate historic structures. This experience means we can help with whatever you need: structural support, waterproofing, or components such as windows, roofing, plazas and sidewalks.

We evaluate the root causes of performance failures and develop solutions that meet the building’s needs and your budget. We approach projects holistically: we solve structural and waterproofing deficiencies while tackling the crucial energy performance challenges. We assist you in navigating codes and local agency review processes. We develop phasing schemes to minimize impacts on building and site accessibility.

We also have a long history of supporting owners in achieving compliance with local façade ordinances. If you need assistance with New York City FISP (formerly Local Law 11) compliance, please contact Gary Mancini at 917.661.7800. If you need assistance with Chicago façade ordinances, please contact Rachel Michelin at 312.596.2102. For Boston ordinances, please contact Lisa Davey or Laura Bashaw at 617.250.4100.
