SAISC PROJECTS Leading from the main lodge through folding stacker doors is the outside leisure and entertainment area which consist of: the marquees tent and braai boma; a large curved pool and a pool/patio deck, whereof the support columns for the patio roof is constructed from a combination of wood and structural steel.The structural support posts for the marquees tent have been included in the design of both the boma and pool deck. A proper interlinked subterranean Wine Cellar was built under the floor of the outside pool/patio deck.The wine cellar is Zimbi’s hidden gem and can be accessed from the bar area through a steel-and-glass connection that houses the steel stairs. The protection of natural flora was of highest importance during design and construction, thus the lodge footprint was fitted between existing trees and today forms an integral part of the aesthetics of Zimbi Lodge. The site has a significant slope from North to South that required careful planning with regard to both the topand underwater flow into a storm water management system that feeds the vleidam situated outside the Lodge footprint. The soil condition, uneven ground and heavy rainfall posed to be challenges during construction but were overcome by extra foundation reinforcement and lifting of the foundations in order to optimize the views. Water sealing of the underground wine cellar posed as a huge stressor during the construction phase The remote location of the lodge required that structural manufactured items had to be planned and designed to accommodate normal transport and ease of installation. The view of the Lodge is towards the South West and all the facilities had to be designed in a manner where the view is optimized and unobstructed.

Internally cladded with 15mm Firestop Gypsum and 102mm Cavity batt insulation in wall cavity. • External cladding of Manufacturing Plant – 65m x 17m x 10m high perimeter. • LSF double story office – 1 200m² over both floors. The total cladded wall area was approximately 1 300m2, excluding openings. • Entertainment deck – 230m². Shiplap cladding was 10m high in 6m Shospec were provided with a complete structural steel skeleton for the factory envelope and gantry crane. This was designed and erected by client. Shospec were then responsible for the roofing and side cladding of the building. modules. All planks were pre-painted. This eliminated additional cost for painting and height access and achieved a quick and complete wall cladding system. Shospec were involved in the entire process from design to completion of Exterior wall cladding comprised of 90mm LSF C-section bracketed to structural girts on the main structure. Walls were then the office block (excluding lying of slab). Comprising of a double storey office block 42.5Lm x 14m (W) x 9.0m (HT) (1 200m2). LSF was chosen due to the clients open mind towards modern construction methods. Steel Construction Vol. 40 No. 4 2016 19
