Project Scale

52,000 gsf / $24M

Sustainable upgrades to the Upper Elementary School.

Colliers provided project management and commissioning services for the addition and renovations to the Upper Elementary School at the Greenwich Country Day School.

The project combined 15,000 gsf of the campus’ original 1890’s farmhouse with a 37,000 gsf classroom addition that houses 19 general classrooms and three specialty classrooms, including a wood shop, art studio, and a developmental learning classroom arranged along two north-south wings. The wings are linked by the open and active central spine that houses a library, media center, and primary gathering space.

Recognized as a High-Performance Building Standards Project for sustainability, the school features the first insulated concrete form (ICF) exterior wall and structure in a school in the state of Connecticut, as well as Electro-chromatic (Automatic Darkening) Glass, and an extensive Photovoltaic solar system on the roof.

As owner’s project manager, Colliers was responsible for representing the owner throughout all phases of the project, facilitating communications between all participating parties, and interfacing with the school’s constituents to ensure communication and coordination of project planning and construction activities.
