Capabilities: Environmental | Deep Foundations | Design Build | Earth Retention | Utilities | Demolition

Bolander services for the HCMC – AOSC project included demolition of two existing buildings, installation of an earth retention system, mass excavation & site utilities.  The most distinguishable feature of our work is the 30,500 SF earth retention system.  At its deepest point, the system is holding back a 36’ vertical face, which requires 3 rows of grouted tie-back anchors.  Bolander teamed with Pete’s Water and Sewer to install site utilities.  The utility challenges include pre-work for a new tunnel crossing 8th Street.  An existing 24” high volume sanitary line was reconfigured to provide clearance for the tunnel.
