Smith Geothermal Energy Project - Winter '25 Overview

(Began summer 2024; runs through fall 2027)

In spring 2024, the Geothermal Energy Project expanded to the Central District for placement of the geothermal distribution pipes. Work throughout the Central District took place through the summer with placement of site fencing, trenching for piping, interior and exterior enabling work on select houses / buildings, and trucking of materials and soils.

Excavation work will began at Sage Hall in mid-December and will continue in this location through early March 2025:

• Sweeney Auditorium's main entrance will not be impacted, however, parking on Sage Circle will be unavailable. The Geo team will make temporary handicap spots available between Sage and Mendenhall to replace spaces offline during construction at Sage Circle.
• Green St will continue to connect to College Lane via road plates during construction.

Excavation for the first section of the upper College Lane distribution pipe running from McCartney Hall to just north of the Sabin-Reed loading dock began on January 2, 2025. This section of upper College Lane will be closed from January 2 through February 28, 2025. Access to the loading dock at Sabin Reed will be from lower College Lane or Green St. during this time.

College Lane will reopen and all construction along College Lane will pause from March 01, 2025, through March 17, 2025, for the Smith College 2025 Bulb Show.

At the completion of the 2025 Bulb Show, excavation for the second section of distribution pipe in upper College Lane will begin and continue through early May 2025. This section will run from

the loading dock at Sabin-Reed to just north of Tyler Dr.:

• Work will not impact the front approach to the Conference Center
• One lane of upper College Lane will remain open for access to the Conference Center loading dock from lower College Lane or Green Street.

Following this phase of work, there will be a short break in activities from mid-May 2025 through mid-August 2025, when excavation activities will restart in front of the Conference Center. Excavation activities for this final section will progress south from the College Club into Tyler House lawn along Green St. Upper College Lane will remain fully open to traffic during this period of construction.
