Extending Utilities to the West End

About this Project

Informed by the development of a long-term energy and sustainability master plan, Dartmouth is undergoing a multi-phase utilities infrastructure project that establishes campus-wide hot and chilled water networks, new communications pathways, and additions and safeguards to the existing electrical utility system. Major highlights include:

  • reconfiguration of the campus electrical distribution system to feed the west campus from the existing north campus electrical substation,
  • extension of chilled water piping to the Thayer/Computer Science building and Arthur L. Irving Institute for Energy and Society, as well as planned future buildings on the west campus,
  • creation of new hot water distribution between Sudikoff and the future site of the new Thayer campus expansion, and
  • provision of additional communication paths for Information Technology (IT) infrastructure.

Phase 1, which occurred Aug. – Nov. 2018, extended the electrical system from the north campus electrical substation near the McLaughlin Cluster to a new electrical duct bank built in front of the Fahey/McLane residence hall. Power for the west end electrical infrastructure was successfully turned over from the former west electric substation to the north campus substation in March 2019.

Phase 2 of this project is scheduled to occur from April – early winter, 2019. This phase will complete the ability to send hot/chilled water from north campus (Sudikoff/McLaughlin) to the end of Tuck Mall, where it will be distributed to west end buildings starting in March 2020. 

Specifically, this project phase will:

  • construct a new energy transfer station in the basement of Sudikoff that will convert existing steam heat to hot water.
  • install hot/chilled water lines in parallel from the west end of Tuck Mall to N. Main Street, north on N. Main Street to Kemeny Hall, and along the pedestrian pathway north of Kemeny Hall, with hot water lines being connected to the new energy transfer station in Sudikoff. 
  • new chilled water piping will be connected to the existing underground north campus chilled water plant under the McLaughlin Cluster. 
  • provide new high voltage electrical distribution to the Choates, with hot and chilled water piping stubs installed for future connections.
