Heritage Cases

The proposed development is for the construction of 2 identical rearing houses positioned either back to back or face to face. The proposed structures are to house 400 ‘Day old Chicks’. These structures will be constructed on concrete strip foundations with high density engineering brick pier walls supporting floated concrete slab floors. Floors will be graded so as to facilitate the effective drainage and removal of generated effluent. External walls will be constructed in double course brickwork that will support the bearing trusses for the roof which in turn will be fixed to span the 4 meter width of the building. Walls will be plastered and painted with approved acrylic paints to a suitable colour both internally and externally. Access and service doors will be provided at the ends of each building. Doors will be industrial quality with louvered finishes so as to provide sufficient air flow capacity thus accommodating the mechanical ventilation system. Whirlybird ventilators will provide for mechanical extraction and ventilation to each of the buildings. The Floor will be provided with adequate drainage and flushing channels which will run the full length of the eleven-meter walls. These channels will discharge to external collection points, which will eventually be connected to a minimum of four 50mm NB UPVC pipes finished flush to the internal face of the wall and discharging over the lip of the external collection channel. Timber trusses with 38mm x 76mm SA Pine purlins will support the 0.5mm galvanised sheet steel roof with fixed underside insulation. The roof will be fixed to the timber purlins with suitable drive screws that will have bonded washers to ensure a sealed and leak free installation. The ostrich camps will comprise designated area in age categories. The proposed ostrich camp is a 7500m2 fenced enclosures. This dedicated enclosure is to be subdivided into four (4) equally sized camps with pedestrian and transit walkways between the individual sub-enclosures. Fencing will comprise of a 1,8-metre-high diamond mesh wire having steel posts and stays firmly grounded in concrete foundations and supplemented by treated wooden droppers at prescribed intervals. A 1.5m wide 60% shade net screen will be attached to the fence. Each ostrich camp will also incorporate a 10m by 20m protective shelter with a minimum height of 2.5m. The shelter is constructed from 150 - 174mm treated gum poles, 50mm x 152mm SA pine bolted to the gum pole with screwing purlins and roofed with corrugated iron sheeting. Weather protection and shading will be provided by installation of a 2.5m high shade net screen fixed to steel wire supports, spaced at 300mm centre to centre at the back of the shelter and at both ends. The identified site has a number of existing boreholes. These boreholes have windmill driven pumps that supply water to a brick and concrete reservoir as well as an existing JoJo tank. The existing water reservoir is impaired and will require rehabilitation before it may be used on a permanent basis. Two (2) dedicated and interconnected JoJo tanks with individual capacities of 5000 litres each will provide water to the proposed development. This water supply will continue to be sourced from existing boreholes with windmill driven submersible pumps. The total manure to be generated by the layer houses will be approximately 480kg per day. The manure will be temporarily stockpiled on an impenetrable (concrete) layer and covered with sails to prevent contamination of the surrounding environment. The stockpile area for this manure will be located approximately 400-600m away to the north of the ostrich houses. Manure will be used on site as fertilizer for crop production. The remaining manure will be sold to local farmers. If there is further remaining manure it will be disposed of to the nearest landfill site. Diseased carcasses will be disposed of an open pit covered by lime. A 4m wide x 4m long x 2m deep pit will be provided at least 400m away from the site. This hole will be fenced off and have a locking mechanism. Carcasses safe for consumption will be taken to a predator farms in the area.
