Agrivaal building refurbishment, Pretoria

WSP was appointed for the engineering services for refurbishment of this historical building in Pretoria. The Agrivaal building was in need of large-scale restoration and refurbishment, and great care had to be taken to preserve the original structure.

Bullet Location: Pretoria
Bullet Client: Department of Public Works
Bullet Role: various

The existing three-storey building is owned by the Department of Public Works and located on the corners of Hamilton and Edmond Streets in the CBD. It was vacated in early 2000 and stood vacant until 2012. The building was approximately 60 years old with great historical significance, so the South African Heritage Resources Association mandated that the building be refurbished and preserved.

Our client needed to revitalise the building and commissioned a large scale restoration and refurbishment project. This required a team of specialists – not only for the general refurbishment, but specifically as the Department wanted to create a Green Star Building – the first national Government building project to target a Green Star certification.

Challenges included the 18m deep excavation and lateral support for the new six-level basement parking.

The design and implementation approach on this 4-Green Star structure yielded benefits such as reduced carbon footprint, lower energy costs, reduced water costs, increased productivity and market leadership in sustainable buildings.

The building is linked to a new ten-storey building with six basement parking levels and a gym, canteen, coffee shops, roof gardens, auditorium and modern conferencing facilities.
