saga between the Architect , Structural Engineer and Steel Detailer , latticed and faceted steel plates were chosen as the superior design option with the inclusion of tensile steel cables connected to the hotel concrete frame as additional support . Each of the 264 plates and their unique connections were analysed , designed , fabricated and installed in their unique position to create the low profile complex multi-curve porte cochère that stands today .
Environmental Impact Consideration The client expressed a keen interest in understanding the topographical profile of the land he envisioned the hotel being developed upon . As a result , a series of tests and investigations were carried out as a precursor to the design . These studies formed an intrinsic part of the design process .
The site falls within the Sterkfontein upper groundwater compartment , and with the presence of Karoo sediment suggested perched groundwater conditions , which had a direct impact on the structural design and architectural footprint of the building . The presence of Black Reef Formation quartzite and dolomite immediately called for the implementation of a site specific Dolomite Risk Management Plan . These conditions set the pace for a design and build of a formidable structure which had a sensitive response to the site conditions and larger context “ designed into its DNA ”. A Stormwater Management Plan
further guided the design from the onset with the inclusion of two stormwater attenuation dams to manage surface runoff thereby protecting the local fauna and flora . This consideration was of particular importance due to the neighbourhood largely comprising of agricultural holdings , and to not overburden the limitations on the existing infrastructure .
