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 insitu 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
