Project Update: In response to the COVID-19 pandemic and State of Emergency, the City of Cambridge issued a directive on March 19, 2020 calling for the suspension of all construction activity in the city no later than close of business, Saturday, March 21. Contractors have until close of business on Thursday, March 26, to fully secure all job sites and ensure make-safe measures are in place. The project team will be on site taking the necessary steps to secure all materials, equipment, and the site in preparation for this temporary work stoppage.

After Thursday, March 26, the contractor will continue to visit the job site as required to monitor it and maintain security. Any limited staff remaining to secure the site has been instructed to adhere to the CDC guidelines regarding hand washing, social distancing, monitoring their health, and staying home if they don’t feel well.

If you have any questions or concerns about this activity now or during the shutdown, please reach out to Harvard Construction Mitigation at mitigation@csl-consulting.com or 617-496-0857.

Originally built in 1893, the house at 109 Irving Street was generously purchased and gifted to Harvard Law School in 2018. Throughout the course of the next year, the historic home will undergo a full restoration both inside and out. The restoration project will begin in mid-November 2019, with project completion scheduled for December 2020. During this time, work crews, construction equipment, and general construction activity will occur between the project’s work hours, Monday through Friday from 7:00 a.m. to 5:00 p.m.
