Old Historic Building Meets New Modern Addition: Creating a new working space for an architectural client

DCI Engineers provided structural design services for the NAC|Architecture Office Building Addition, which connects to the firm’s original historic brick building.

Project Highlights

The structure has several features that challenged the design team, including 9’ cantilevered slabs, zero offsets at the property lines, and large skylights in the building’s roof.
Consists of 7” deep post-tensioned slabs and 14” slab beams that are support by cast-in-place concrete columns and walls.
Post-tensioned concrete was chosen for the design in order to minimize structural depths, so that the floor-to-floor heights could be matched to the existing building.
