Boston Public Library

A Copley Square landmark, the Johnson building addition to the Central Branch of the Boston Public Library reopened to the public in 2016 following a three-year, $78 million renovation project.

Designed by William Rawn Associates, the renovation called for the removal of the granite plinths that covered the building’s windows, creating an inviting, light-filled space that reconnected the building to the street. Other highlights of the project included a revamped lecture hall, a new innovation center and hi-tech community learning center, an enlarged fiction section and new ways of book browsing, a state-of-the-art Welcome Center, digital imaging suite, and an enterprise retail space that blends seamlessly with the library.

Sunrise’s scope of work included the installation of an all-glass curtainwall system with all-glass vestibules supplied by Sentech Architectural Systems; fabrication and installation of structural steel perimeter attachment system and stainless steel perimeter cladding; and installation of corrugated metal and aluminum composite panels.
