Below shows an outline of the proposed site hoarding layout, the site is in a very narrow and tight location so hoarding must be located effectively so that it still allows for pedestrians to use the public footpaths that run parallel to the site. Hoarding is erected mainly due to site safe and to stop from any unauthorised persons from accessing. The site is located on a quite area that is susceptible to crime as the streets are not very well lit and CCTV is not present. Hoarding also provides safety as it acts as a shield for the general public who could happen to be walking in close proximity of the site and stops them from accidentally wondering onto site. As there are businesses that will still be in operation to the north west of the site as the image below states, the hoarding will have to be placed so that it does not effect their day to day running of their business. By placing the hoarding where it is it will mean that workers can still access it on foot and by car and also their site deliveries can be unaffected.
Noise reducing hoarding should be considered due to residential properties in close proximity to the site. This will minimise the travel of sound and also vibrations which will occur during the demolition and piling phase of the project. It is said that these can reduce noise by up to 34 decibels.
Below shows an outline of the proposed location and layout of the site facilities which are extremely important in order to comply with the CDM Regulations 2015.
The provision of site welfare facilities is specified under schedule 2 of the CDM Regulations 2015 which is shown below. The welfare, office spaces and first aid facilities will be located in the court yard which is to the left of the building as shown on the diagram below. This will provide site workers with a warm indoor space where they can have a break and eat their lunch. Site offices will allow for the CPM, site manager and other office workers to carry paper work. A first aid point must be located if injuries occur on site to workers, this will be located within the same building as the site offices.
To the left is an example of what kind of temporary welfare pods can be used for construction sites. To save space these can also be stacked on top of each other as shown in the image below.
The site storage will be secure shipping container which an example is shown below, where all site materials and equipment are kept when the site is closed. These should be locked whenever no one is working on site to make sure that no trespassers try to steal them. This will be located in the court yard close to site so that workers don't have to travel far to bring materials to the site.
Fire exits and assembly points are extremely important when conducting a construction project and it is important that all workers and also everyone that enters on to site knows where these points are in the event of a fire. As heavy machinery is being used and also the possibility of hot works this could easily lead to a fire breaking out on site. Fire exits and assembly points will be clearly sign posted with direction arrows leading the way. A designated fire marshal will also be on site who will make sure that if a fire does break out all the safety procedures are followed and adhered to.
Below shows the image of where the proposed fire assembly point will be for this development for if a fire was to break out on site. Alarm bells would sound which would indicate to the workers that a fire is present, they would then follow the fire exit sign that is shown above, which would then lead them to the fire assembly point which again would be clearly sign posted. By this time the fire brigade will have been notified, the fire marshal would then have the job of collecting all the names of the workers on a register to make sure nobody has been left behind on site.
Site security discourages trespassers from attempting to enter the site during off hours. Firstly this could result in materials and equipment being stolen which would delay the project and also add further cost implications but also secondly if an unauthorised person or persons does gain access to the site and they injure themselves, and it can be deemed as preventable this can be seen as negligence meaning the developers and the contractors could face penalties under the occupiers liability act 1984. In order to deter trespassers from entering the site CCTV should be put in place and the site should remain brightly lit at night (not too bright to distract neighbouring residential properties), also the hoarding and the site entrance/exit should be checked every night before leaving side.
Below shows an outline of the proposed site logistics plan that will be carried out when deliveries of materials takes place. Delivery vehicles will access from the Penistone Road side taking an immediate left turn onto Dixon Street. As there is a business next door that will still be in operation it is important that we the CPM, contractor and the planner stay in communication with these so that deliveries can be staged in order not to clash with each other and cause congestion. Once the delivery vehicle arrives the site entrance gate will be opened so that they can then drive onto side and the labourers can unload the delivery. They will then carry on driving forward where the exit gate will open and they will proceed to depart the site. A traffic operations manager should be used so that deliveries run smoothly.
Below shows an outline of the proposed boarding for a cofferdam which will be put into place to stop the river from flooding the site once the existing building is demolished. There are several different types of cofferdams and for this particular development a single-walled cofferdam would be recommended which can withstand water of up to 6 metres deep. This process starts with driving timber sheets into the bed of the river along the boundaries of the site. After, on the inside of these timber sheets, steel sheets are then introduced, this helps to form a barrier to stop water from penetrating the site and causing delays and damages to the works. What water is left in cofferdam once it is constructed is then pumped out.
