NJ State Museum Roof Donor Antenna

Trenton, New Jersey

Project Overview

MFS Consulting Engineers & Surveyor, DPC provided structural engineering services for the New Jersey State Museum Roof Donor Antenna project in Trenton, New Jersey. The scope of the work was to support the relocation of the roof-mounted antenna. Initially, the antenna was designed to be attached to the northern penthouse roof level. However, the project scope was modified to move the antenna to the southwest corner of the penthouse, near an existing shaft opening. In this revised configuration, the antenna was to be ballast-mounted directly on the roof membrane rather than affixed to the wall.

MFS conducted a site visit to observe the existing conditions of the penthouse roof and confirmed the proposed new antenna location. After reviewing the record structural drawings, MFS performed a detailed structural analysis of the penthouse roof framing. This analysis accounted for the various loads the roof would be subjected to, including dead, live, snow, and wind loads, in accordance with relevant building codes. MFS ensured that the existing structural framing could support the antenna without requiring modifications, and a letter memorandum detailing the findings was issued, signed by a New Jersey professional engineer.

Additionally, MFS provided structural CAD support to produce detailed drawings for the roof penetration required for the pull-box and a design loading criteria schedule that outlined the applicable loads. Throughout the project, MFS provided construction administration services, including reviewing submittals, responding to contractor RFIs, and preparing or modifying construction sketches. MFS also attended construction progress meetings and conducted site visits for general observance, ensuring that the structural work aligned with the project’s scope and specifications.
