Preparing AlexRenew’s Campus for the RiverRenew Tunnel System

The decommissioning and demolition of Building J is an essential step toward making space for the Tunnel System Project.

To pave the way for the Tunnel System Project, an existing building on AlexRenew’s campus, known as Building J, must be demolished.

Building J housed AlexRenew’s laboratory, locker rooms, and other facilities for over 20 years. Following the relocation of AlexRenew’s essential workers and facilities to Buildings G/1 and G/2, utilities were disconnected to prepare Building J for demolition.

On November 25, dismantling of Building J began using an excavator with hydraulic attachments that removed portions of the structure piece by piece. These materials were then loaded into a truck for recycling or disposal.

The removal of Building J will create enough space to construct two large shafts, approximately 65 feet and 35 feet in diameter, respectively, and 12 stories deep. These shafts will serve two purposes:

As of December 10, AlexRenew’s construction partners, Clark and ACECO, have safely demolished the above-ground portion of Building J. Demolition activities are anticipated to be complete by January 2021.
