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.
