Dimock Acute Treatment Center

Roxbury, MA


The Dimock Center is a long-term valued client of Timberline’s with multiple projects completed and underway on its dense urban campus. This 14-month gut rehabilitation project restored and revitalized the aging 100-year old Acute Treatment Center for substance abuse disorder. The Dimock campus houses one of only three inpatient detox facilities in Boston.

Substantial exterior work comprised repair and restoration of the masonry facade and slate roof, refurbishing of existing windows as well as construction of a ground-up addition. Interior renovations created new program areas including residential double-occupancy units, open nurses’ stations, integrated case management offices, multipurpose community rooms, integrated security and an outpatient treatment area. Timberline installed all new building systems as well as structural replacements.

The construction team coordinated around existing water, gas & sprinkler lines that had to remain active to support adjacent buildings. Timberline installed a new elevator to serve the three levels of the existing main entry building. Special drilling techniques and a chemical expansion process was used to excavate the elevator pit from solid rock while protecting the adjacent bearing elements and mechanical systems of the historic structure.

The project serves to attract and retain expert treatment providers standing as a leading example for future treatment facilities.

This project received the Mayor Thomas M. Menino Legacy Award through Preservation Massachusetts, an award that recognizes preservation projects that are transformative, catalytic, embrace the community, create partnerships and revitalize the best of the past to make something good for the future.
