While last year’s work on the Dedham Square Improvement Project took place almost entirely during the day, this year the work will be mainly performed at night, according to a recently released project update.
But the project will not begin again until late May or early June, as project contractor FED Corp. must wait for NStar to complete an unaffiliated gas main replacement project in and around Dedham Square, the update said.
Thursday’s update was the first since the project’s winter shutdown in November; project leaders ordinarily release updates each week.
As of Thursday, FED Corp. had worked a total of 162.5 shifts of the maximum of 366 allowed, according to the release. But 147.5 of those had been day shifts, the release said.
In order to strike a balance between businesses, who are hurt by daytime work, and residents, who must endure noise during night construction, selectmen decided in September 2011 that work should be done 50-50 during night and day.
Night shifts will primarily be taking place on Sunday night through Thursday night, and will begin with full depth roadway reconstruction, according to the release.
All project work must be completed by Dec. 3.
