This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.
This report has been commissioned for the sole benefit of the client for the preparation for a detailed method statement for demolition and site clearance works associated with the construction of the new high specification health centre on Meade Street. The report will concentrate on the site arrangements and layout for the new Meade health centre site from the start of construction to the handover of the site. The labour resource which will be needed for this project will be discussed and assessed in each phase for demolition and site clearance works. The purpose of this report is to ensure efficient construction of the Health Centre whilst simultaneously causing minimum disruption to the neighbouring community which consists of:
1. The users and operators of the Sports Hall adjacent to the South East of the site.
2. The residents living towards the North of Floyd Road.
3. The Primary school students and staff located at the far side of the sports hall with an entrance situated on Floyd Road.
4. The local shops on the opposite side of Meade Street
5. Commuters travelling through Meade Street and Floyd Road.
1.1 Scope of Works
The works involved on the site involve:
1. The demolition and clearance of the existing Doctor's Surgery.
2. The erection of the Temporary Surgery on the proposed car park area.
3. The construction of a high specification Health centre.
4. The construction of the car park.
1.2 The Contract
The contract period for this project is 65 weeks and the contract sum is £5.7 million with liquidated damages set at £7,500 a week. The date for possession of the site is set on the 9th November 2009.
1.3 Hours of Works
It is anticipated that the core working hours for demolition and construction will be set out as follows:
0800 - 1800 hours Monday to Friday
0800 - 1300 hours on Saturday; and
No work on Sunday, Bank Holidays and any other Public Holidays 3 | P a g e
2.0 Site Arrangements and Logistics
The management of the site is crucial for a successful flowing project which delivers on time. With the site arrangements are planned for in advance for each phase of the project, this demonstrates the contractor's competence and understanding towards all the health, safety and welfare requirements needed for the projects success. This will require a dedicated and detailed plan and control of the site layout as well as its management. For the interest of health and safety and the well being of all labourers working on site, prior to any commencement of work, all employees will be aware of all site rules and regulations and the hazards associated with the site. Training will be provided if necessary to inform and educate the labourers on site health and safety and the regulations that need abiding by whilst working. All staff will be asked to present their CSCS cards to ensure their occupational competence. No labourer will be allowed to work on site without presenting their CSCS card.
2.1 Site Offices
The site offices for the Meade health centre project are shown on Section 3. This will remain its position to the point where the new health centre is constructed and works on the car park begin. It will then be moved to a different location as seen in Section 3. The site 'clocking in' office will be situated immediately after the access point in Floyd Road. The primary reason for this is that it creates a professional impression and allows easy access for the client, staff and suppliers and prevents unauthorised access of personnel. This ensures that there is sufficient measures taken for site security especially as children from the school nearby might try to stroll in to see the working area. There will be another access point situated on Floyd Road at the other end of the site. This will come in use for deliveries and disposal of stockpile material which is talked about later in Section 4.15. For health and safety reasons, two access points will be needed in the case of a fire i.e. a fire escape route. Suitable signage will be posted around the site showing the fire escape route.
With the aid of a gates man at the main site access point, it is possible to have pedestrian and vehicular access the same as the gates man will help direct delivery trucks to the right location with a sense of awareness to ensure the safety of site workers. Therefore, a necessary precaution to take into account at the access point is to have clear visibility both on and off site so pedestrians and cars passing by can see if trucks/plants are leaving the site as well as employees on site being able to see trucks entering the site. With people having greater awareness of what's going on around them, this minimises the risk of a potential accident.
2.2 Client's Offices
A mobile office with an area of 15m2 is to be provided for the client's visiting staff on site. Along with the office, the client shall have their own toilet/washing facility which is separate to the workers on site. The gates man will hold the key to the client's offices and will only allow the client's staff to make use of it. An important factor that will remain the same throughout the project is that the gates man will have been provided with adequate training to act as the gates man and would have been informed with what their duties and responsibilities are. Only the client's visitors will gain access to the office. 4 | P a g e
There have been provisions made for 2 portable toilet cabins (1.5m2 in area with built in washing facilities and drainage/supply tanks) around the site. The cabins can be used by both males and females and will be provided with a locking function so once the cabin is occupied, no other member can have access to the cabin. The washing facility includes a soap dispenser so the employee eliminates germs for hygiene requirements. The toilets will be cleaned by a labourer appointed by site manager ensuring they are clean and that there are adequate level of toilet rolls and soap throughout the day.
2.4 Hot and Cold Water Supply
There will be adequate provisions made for the supply for both hot and cold water supply. A storage tank will be built into the oasis cabin unit which and will be changed frequently to prevent water from being contaminated and stale. There will be a separate tap for drinking water which will be marked for clarity reasons preventing workers from drinking contaminated water. Cups and glasses will be provided for drinking facilities for employees. The site manager will appoint a labourer to clean the cabin at the end of each day at the very least to ensure a tidy working/resting area.
2.5 Employees Changing Room and Storage Area
The employees will be assigned a locker when checking in on site for them to put clothing and other personal belongings in for safe keeping. This area will be located in the oasis unit which the facility allows for toilets, washing, changing, resting and canteen area. This will be adequate enough for the employees to have their lockers and to gather their clothing to wear on site (hard hat, reflective jacket, gloves etc.). Men and women will be able to change separately as there are two changing rooms in the site office. The oasis unit will contain a suitable first aid box which will only be available to qualified first aider.
2.6 Accident Procedure
A first aider will be made at the main contractor's discretion. The first aider will take care of all injuries and keep a register of all accidents and injuries that occur on site whether they are minor or major. Major injuries will be treated by off-site personnel and recorded. The recorded information will be analysed and interpreted by the site manager to see what measures need to be taken to prevent the same injury happening again. They will also analyse the labour operatives competence and see whether or not they acquire training in the work they need to carry out to they can work in a safe manner not endangering others as well as themselves.
2.7 Resting/Canteen Facilities
The resting facility will be incorporated with the canteen facility where employees can have their lunch and break. This facility will be incorporated within the oasis units themselves saving time, cost and money. The resting/canteen facility will have tables and chairs accommodating up to 24 employees, a kettle which boils water for employees and a means of warming up food such as a microwave. The cabin will provide shelter for employees and will have windows to open to help ventilate the cabin if feeling discomfort. Their will be provisions made for adequate heating facilities as it is winter and the weather will be very 5 | P a g e
cold. Signage will be put up in the cabin to inform workers to keep the canteen tidy and also no smoking is permitted in the cabin as well as on-site for health and safety reasons.
2.8 Heating Requirements
Gas cylinders will be used to heat up the porter cabins. The cabins will be detached and replaced by trained colleagues ensuring that the cylinder is secure without any leakages. In best practice, the cylinders will be stored outside the accommodation in a well ventilated area including overnight. The colleagues in charge of maintaining the cylinder will ensure it is properly on/off when in/not in use. For health and safety reasons, all cabins will be fitted with a mounted carbon monoxide detector in case of leakages preventing poisoning.
2.9 Materials Storage
Materials are going to be stored in the location shown in the drawings (see section 3). Pre planning of material storage and location is necessary to ensure material safety and helps reduce material wastage as well as time wastage. The deliveries of the material will be made on site with the route the delivery vehicles takes on site highlighted in the drawings. They will then be off loaded mechanically (using the truck's machinery itself, fork lift truck or crane) onto the desired location. Materials which are delivered onto the site but aren't needed at that given moment will be stored in site containers which are locked to prevent theft or damage. The materials, when needed are then allocated to their designated area by fork lift trucks or cranes. The plant which delivers the material on the desired location will have its own road mapping so they stick to the routes that are given. This is to prevent running someone over as well as knocking something down. The layouts are shown on the drawing in the next section. Materials which are used and stored out in the open overnight (bricks, blocks) will have an adequate material covering around out to protect it from the weather and protects its visibility to prevent theft. Before delivery vehicles leave the site, adequate wheel washing facilities will be in place to clean the mud of tyres preventing dirt from polluting the footpath and roads. This is another measure taken to keep the local community happy as possible. The contaminated water will then be treated and disposed of in an environmentally friendly way.
2.10 Waste Management
As well as accommodating for all the materials needed for the construction of the new health centre, careful planning and consideration needs to be taken towards the handling of the demolition and waste materials. This is why (with the appointment of a waste management controller), the waste manager will have sufficient skips for all the different types of materials that need recycling as well as allocating the perfect area in which to dispose the waste in. Recyclable skips will be in place and co-ordinated in a way when so the replacement skip comes in time to replace to full skip. All other materials which aren't recyclable will be positioned in a separate skip to be disposed of in a landfill site to keep the co-ordination of site cleanliness in order. All skips will have boards saying which materials can disposed in a particular skip allowing labourers to separate recyclable materials into the different skips. The boards provide clarity and transparency with the workforce employed on site. With regards to the demolition of the external walls, load bearing walls and foundations, the rubble generated will be position in a stock pile (see section 3). The stockpile will then be disposed off to a landfill site with the use of an eight wheel tipper. The 360 degree excavator will load the wheel tipper with the rubble to be disposed off site. 6 | P a g e
Access point 2 will be used by the trucks to dispose of the stockpile. The waste management plans will enforce and abide by the Site Waste Management Plans Regulations 2008 and ensure all recyclable materials are recycled in appropriate disposal plants.
2.11 Ancillary Arrangements
Prior to any construction work starting on site, electrical, gas and water supply will be cut off from the perimeter of the site. This means the use of generators will be needed for lighting purposes on site, in the temporary surgery and electricity for the use of mechanical tools. Gas cylinders will be used to heat up the oasis cabin units. Storage tankers will be used to store fresh water for cleaning and drinking purposes. The will be enough electricity provided by the 110 Volts DC generator for the labourers on site to work on as well as powering the cabins and the temporary surgery. Along with the generator, emergency lighting will also be installed in the case of a power shortage hence blackouts.
2.12 Site perimeter
Prior to the commencement of any demolition work taking place, the site will need to be boarded off from the general public for their safety as well as site security issues. Therefore in the context of the project, the hoarding will need to be 2.4metres high consisting of a continuous ply material. This is to prevent debris from the deconstruction and construction phase from falling onto the public and roads causing nuisance. Posts for the hoarding will be cemented in ground to ensure they don't buckle in heavy winds and so that they are secure. The top of the hoardings will have barbed wire running throughout the site perimeter to prevent trespassers breaking and entering into the site. Site access points will be fitted with gates and surveillance (the gateman). The gates man will be in charge of opening and closing the site when necessary. When the working day is complete, the gates will be locked once the site is unoccupied. The perimeter of the hoarding will include signage showing where the site access/egress and the hazards that are faced to the public if they were to enter the site without permission. The hoarding will include the name, address and contact for the contracting authority working on site to answer any of the publics query or for the public to report damage to the hoarding or trespassers on the health centre site. There will also be signage showing access and egress points for workers on site and patients/employees who wish to enter the temporary surgery.
2.13 Site Access and Egress
The site will have three access points, two on Floyd road and a new access point which will be situated on Meade Street. The Floyd road access points will be for the entry and exit for site personnel and deliveries whereas the access point on Meade street will primarily be for the employees and patients who for the temporary surgery (see Erection of the Temporary Surgery). The Floyd road access point 1 will have all plant deliveries through this point and gateman will always be at the egress and exit to co-ordinate the movement of deliveries of plant on and off site. Access point 2 will be used as a fire exit and also in the demolition stage, the access point for disposal of rubble and debris to landfill sites. The gateman will also be part of the site security team where the gateman will register all personnel entering or exiting the site, deliveries on and off site and to keep vandals away. The gateman will find co-ordinate deliveries into the correct delivery zone as there are no parking facilities on Floyd road due to the double yellow lines. The Floyd road access points and Meade Street access point will run independently from each other therefore the construction and 7 | P a g e
deconstruction of the new health centre should have no effect on the running of the temporary surgery. 2.4 metre high ply hoarding will separate the temporary surgery to the new health centre site and the hoarding will be laid in a way to develop a path for the employees and patients to the temporary surgery. The hoarding which separates the demolition site to the temporary surgery will have directional arrows to guide the public to the entrance and exit to the temporary surgery and of the site. This is good practice for the health and safety prospective as well as site logistics to keep pedestrian access as well as vehicular access completely segregated.
Each supplier will have their own views on delivery arrangements. From analysing the local environment around the site, the problem occurs on Floyd road where deliveries are coming through that the road has double yellow lines, it is an extremely busy suburban road with school children using road as a route to the school down the road and is extremely busy at peak times. Therefore deliveries are highly recommended fit around times before and after school starts/finishes, and off peak times if possible. All deliveries will need to be kept of the street and on site on the delivery unloading bay. The delivered goods will be unloaded either manually or mechanically with trucks having their own unloading equipment. The goods will then be stored in railway bunkers and locked to prevent theft or damage and then brought out of storage when needed in the construction phase. The gateman will manage deliveries and will incorporate a 'roll in roll out system' where the delivery trucks must follow the flow of traffic into the site and not park outside the site. This will reduce disturbance to the local neighbours and community and the general public and ensure that there is no unauthorised on street loading/unloading which has clear safety and traffic management issues. Delivery trucks when leaving the site will have their wheels washed as described earlier.
The intention is to place a 60m luffing jib crane on the site as shown on the drawings (see section 3). The span of 60 metres will cover the area in which the new health centre is going to sit on as well as where all materials will be situated along the site. The crane will be erected on the ground which would have tests done to ensure the surface on which it sits on can carry the load of the crane. The crane will be anchored into place and positioned so that the crane will not make sudden unexpected movements (especially in windy weather conditions) when in operation. Before the crane is used for operation, the crane will undergo safety checks on a day to day basis by the main contractor and the operator/s to ensure that it is in an operable condition. Only a licensed and qualified operator will operate the crane and to ensure this, the operator will show evidence that he/she is qualified to operate the crane. Only then will the main contractor hand over the keys to operate the crane. It should be mentioned that the main contractor will give the keys to the operator at the start of the day and collect them at the end for safety purposes i.e. they will not be left in the crane. The crane operator will still need to comply with safety regulations and wear a hard hats and high visibility vests as long as they are on the construction site. The crane will use metal chains for the lifting of materials for transport purposes and will be tied securely by a labourer until it is safe to lift and move. The labourer in this case (because it is a small project) will be: 8 | P a g e
1. The slingers - who attaches and detaches the goods from the crane,
2. The signaller - relaying directions to the operator either through hand signals or radio communication.
3. The banksman - for guiding the crane on and off site safely.
Ideally steel beams or timber joists will be tied at the centre of gravity to prevent the materials from tilting and in the worse case scenario, if not tied correctly, falling from a height which is very dangerous. If needed, tag lines (made from rope) will be tied on each end of the beam where labourers will hold when elevated (as well as the crane to assist in keeping control of the beam). The banksman will then slowly help move the materials to a safe and convenient place. Direct communication will be used by all labourers and operators carrying out this method either by radio and/or by hand signals.
2.16 The Erection of the Temporary Surgery
It is anticipated that the erection of the temporary surgery will take place prior to the deconstruction of the existing surgery. This is to ensure that there is minimal inconvenience for the patients and employees who are the sole users and operators of the surgery. Mobile offices will be bought onto site and conjoined to make a useable temporary surgery. Mobiles will be joined together and fitted out with all the building services needed to make it functional. The mobiles will be bought onto the site on a delivery truck which is capable of lifting and positioning the mobiles in place. The ground conditions will be tested before to ensure that the ground will be able to withstand the loads of the temporary surgery. The mobiles will then be secured together and the correct adjustments will be made to ensure that the mobiles are level and secure. The fit out of the mobile surgery will include sufficient electricity and sockets/switches to satisfy the lighting and connection of equipment/facilities requirements. The temporary surgery will also facilitate for welfare facilities providing male/female lavatory facilities which both have a hot and cold water supply incorporated. The entrance of the surgery will be separate and completely independent from the existing surgery. The entrance into the temporary surgery will have a ramp access to cater for those in wheel chairs and mobile devices. For the interest and safety of the patients and employees, sufficient hoarding will separate the existing and temporary surgery making them independent from one another. This will prevent debris falling from the construction/demolition site and injuring the public. The safety and best interests for the public is vital to deliver this project successfully. This is why there will be barriers/hoarding along with suitable signage re-routing the public towards the entrance of the temporary surgery and the hazards associated with the construction site. 9 | P a g e
