Description Ridge 5, known as Strauss Daly Place, is a new office development in the prestigious Ridgeside Office Park in Umhlanga, KwaZulu Natal. The building comprises four levels of basement parking, one level of open parking and eight levels of office accommodation with a concrete roof slab. The total Gross Building Area is 35,000m², with approximately 10,000m2 of this being lettable office space. The building is designed as a reinforced concrete frame with post tensioned slabs, and is supported on piled foundations. Pile diameters vary between 300mm and 750mm diameter. An unusual feature of the building is the raking off-shutter concrete wall to the south-west elevation, with cantilever balconies projecting from the face of the wall. Due to the tight space constraints on the site, anchored contiguous piled walls were utilised to form the basement levels, in addition to conventional reinforced concrete retaining walls. The process of excavating for the basement had to run hand-in-hand with installation of gunite facing to the contiguous piled walls, which resulted in a very complicated earthworks operation. The building comprises four levels of basement parking, one level of open parking and eight levels of office accommodation with a concrete roof slab Scope of Services Hatch Goba (formerly Goba) were appointed by Chanter Properties to carry out the civil and structural design for the new office block. Hatch Goba were able to provide an efficient structural solution on a very restricted site which came in on budget and within the tight development timeframes.
