Description

Distinguished by a twinned structural lantern at the building crown, the metal and glass exterior rises nearly 60 feet above the top of the main structure. An outdoor plaza with shade trees and a three story glass and marble lobby give the building further distinction from the street.

The owner’s lease obligation dictated an aggressive schedule to secure the major tenant. The 8 months from the start of design to the construction start included entitlement acquisition through the zoning process, design of the building, and overlapping of packages to allow for early release of subsurface permit documents.

Beginning with the demolition of the existing building, we minimized time, costs, and construction debris by leaving the below grade structure component intact and bore through with caissons. A deliberate implementation strategy, timely decision-making, an intimate working knowledge of the City’s regulatory entities and a cooperative relationship with the contractor enabled delivery of the project for tenant occupancy in 33 months.
