The Challenge: The project took place at one of the busiest intersections and sidewalks in Boston, all while the building remained fully occupied. There were many surprises with the existing roof deck that were discovered during construction but the project team was able to adjust and keep the project moving with minimal impact to the schedule. Multi-year phase plan restoration.

Project Scope:

  • 420 Boylston Street, aka "The Berkeley Building", is a 6 story commercial building constructed in 1905.

  • Wessling Architects was engaged by A.W. Perry to assist with a complete roof replacement in 2014.

  • Existing roof was a ballast EPDM that was coming to the end of its life cycle. The client was proactive and decided to completely remove the existing roof and replace it with a new reinforced adhered EPDM system.

  • Multi-phased facade restoration completed by Heritage Restoration over the summers of 2017-2019.

  • Full cleaning of facades, terracotta crack and spall repairs, mortar joint restoration, 100% repainting of all wood window frames and cast iron spandrels.

  • Repair of rotted wood, resecurement of existing wood trim and cast iron elements, installation of raised sealant joints at skyward facing joints.

  • Replacement of all wood perimeter and metal panel sealants, selective stucco repairs and coating of existing previously coated copper roofs over the bays.

  • City of Boston Facade Inspection
