Re-roofing a Landmark: NJR Delivers Engineering Precision at NWU Auditorium NJR Potchefstroom was recently commissioned by North-West University (NWU) to solve a persistent leak in the auditorium roof—a complex task due to the very low pitch of the existing structure. Rather than replace the roof entirely, the team opted to erect a new roof structure over the old one. This solution ensured minimal disruption to ongoing activities inside the auditorium. In the absence of an appointed architect, NJR joined the design team directly, offering both product expertise and technical input. Our proposed light steel truss system was reviewed and approved by the project’s structural engineer. The project posed significant engineering challenges. The 40-year-old auditorium had no CAD documentation—only original paper plans. The building’s large, kite-shaped roof spans 70 metres diagonally and 35 metres across the shorter axis, with perimeter wall heights reaching 12 metres.
