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.  The project earned a LEED Silver rating by daylight harvesting, solar controlled blind systems, and the use of high recycled content and low-emitting materials.

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.
