Site Management and Engineering - Essay Example For further safety of the site, an additional gate is placed just in front of the construction area, this is for occasional use. For instance movement of formwork when it is no longer required, this will not disrupt the movement at the entrance and in movement corridors, further making the site safe. The plant area is kept just in front of the construction area, as it will avoid to and fro movement of materials to construction site and save money, manpower and time. The junk area and storage area is kept at the corner end, this place will have minimum disturbance to corridor movement, will be safe from any theft and access to general public could be monitored as it is far from the working area. Lastly the rest area and cafeteria is kept opposite and away from the construction area, this will have a psychological effect on the workers as they will feel easy and this area will have least construction activities, hence least safety supervision will be required in this crowded area. Q 2 a) The most appropriate formwork system for in-situ concreting of lift walls would be Jump formwork system. This system consists of two components one being the formwork itself and the other the working platform from which the steel is fixed, concrete is poured. This type of formwork is self supporting and is most suitable for vertical elements such as lift walls. As the formwork is designed for staged processing hence it enables the speedy and efficient construction. The material of choice for our construction site would be Steel, this enables a perfect surface finish. But these steel frames must be properly designed before concrete is poured. The individual panels are attached to the frames which have different supporting conditions such roller support, once the concrete is poured and set, the panel is rolled back and a perfect finish is acquired. In the next process the jacks and lifting mechanism lifts the whole frame up one stage. The process is repeated again where panels are attached and then concrete is done. This shift of formwork and its components can take as less as 2 hours. This gives speedy and time effective solutions. Some of the views of the system made by Transkon FormworkSystem, are given in the figures below. Transkon are specialist of the field and renowned for new innovative formwork solutions. Q2 b) Although, the jump formwork provides several benefits such as the increase in construction speed and low resource requirement in terms of manpower. But at the same time it possesses considerable hazards against safety of workers and failure of formwork structural system. As mentioned earlier the formwork is self-supporting and self-climbing, hence there is the chance of structural failures of formwork, in case any joint or member fails and damages will be collateral. The first step towards safety is properly checked safe design of formwork and falsework. As these formworks work at a height hence an efficient free-fall breaking devices must be incorporated in the design. Then the platform in use must always be clear from any unnecessary material and waste should be removed as soon as possible. In addition a well maintained false work must be used for erection of the formwork and the platform. Each component must be oiled and painted properly. If excessive damages are seen in these parts they must be replaced. As our material of choice for false work and formwork is steel and metals hence corrosion of these components is to be monitored by the safety supervision team. Braces must be fastened properly, edge protections should be erected on the corners.     Ã‚
