Civil Engineer in Nelspruit

Various projects with an estimated value of R 750 million (Surveying, design and documentation, site supervision, project management, project coordination with professional team.) Pro.com Civil, Structural and Green Building Consultants is a vibrant and experienced Engineering company providing specialist expertise on environmental and green building projects and products. Fanie Joubert, the sole director, has 30 years experience in a multitude of civil and structural projects, including the construction of schools, hospitals and multi storey buildings. Pro.com is involved in the planning and design of various building projects,and has recently started with the planning, design, supply and construction of earth retaining structures and erosion protection systems, such as gabion basket structures. The conservation of the Environment plays an important role in our planning and design and we always investigate alternative building methods to achieve play a positive role and to achieve our goal. With ever increasing building costs, the requirement for rapid building and greater awareness of energy conservation as an important aspect of building design, expanded polystyrene (EPS) is becoming increasingly used in modern day construction. The system comprises a priority high strength galvanized steel rib which supports the high density PES EPS void formers. The system is completed by the placement of reinforcing bars between the PES blocks in both directions, reinforcing mesh above the blocks and concrete to fill the channels, encapsulate the rebar and mesh to form the structure of the floor slab. The beams which are created by the concrete infill and rebar in the gaps between the PES blocks creates a monolithic structure. The PES void formers are left in place and act both as a thermal and sound insulator. These are propped at 1,6 meter intervals to support the wet concrete and construction loading. 6) If needed, formwork is placed around the perimeter of the floor area and service ducts to confine the concrete pour. Where complex designs are required, incorporating angles, split levels and curves System offers increased versatility as the blocks and channels can easily be cut to. The system components are lightweight and can be installed without heavy lifting equipment or large labour crews Eco Slab Polystyrene Blocks easy to handle on site. To support the weight of the concrete until the concrete has cured the deck has to be propped The propping spacing can be extended as the dead load of slab system is 150kg/m² less than an equivalent concrete rib and block slab. The routine is to place the support channels and blocks and then prop.Propping is typically at 1,6 meter centers. Polystyrene Void Formers are strong and durable The load supporting capability is designed into the system using the variables of; support beams and columns, slab beam depth, reinforcement configuration and concrete strength. Concrete usage varies according to the height of the blocks with the deeper blocks requiring more concrete, as the concrete beams between the blocks are deeper. The amount of concrete used slab does not vary greatly from thinnest to deepest slab. This is what makes the slab system cost competitive against concrete slabs, particularly in situ slabs. The plastert has excellent adhesion to both the steel rib and the polystyrene TASS blocks, can be smooth finished and does not crack over time. The droppers are fixed to the underside of the steel channel which run at 600mm centers. For parkades and basements which do not need a high aesthetic finish the under side of the blocks can be painted with any high quality, acrylic, water based paint. components fit closely together and the underside is therefore flat, a painted finish is perfectly acceptable. This has beneficial implications for the overall structural design of the building.
