Provide structural design support needed to expand and/or upgrade ensuring the success of your improvements.

JN Engineering provides professional design services required to convert or improve tenant spaces ranging from single tenant spaces to entire buildings. We coordinate with architectural, mechanical, and other design consultants to determine whether structural revisions to the building are required to support new equipment, openings, and design components. Structural design for tenant improvement ranges from designing support for a sliding glass door and ceiling soffit framing, to anchorage of shelves, signage, bookcases, and displays.
