Construction Method Statement Example

twirl Method Statement Example1.0 IntroductionThis manifestation Method Statement describes the development of six houses in three monovular semi-detached blocks on a plot of land. The document give suffice for the volume of encounters undertaken during the construction but leave require alterations or additions for authentic(prenominal) projects. This mode statement is a qualified assessment based on current information and is subject to refinement as the project evolves. This method statement is prepargond to discuss about all the construction wait on and operations and also emphasize on the health, safety and environmental concerns.2.0 advance twists2.1 Access and Material DistributionConstant flow of dishonor is needed during the construction period. Small door proud channels and driveways unitedly with short-lived roads argon constructed to define come in circulation routes and provide a suited surface for plant movement (Chudley Greeno, 2008, p.118). A sma ll access road is set up nearby the storage area of the lay to charm materials that are required within a short topographic point of time. A forklift go forth be apply for material offloading and distribution around the site. The reparation of the access road shows in the Figure 1 site layout plan. Moreover, the road result be subjected to light and atrocious day to day trading such as cover speech, steel delivery lorries, brick and block delivery lorries and delivery vehicles generally. All the deliveries leave be fitted into a delivery history system which is controlled by site personnel under guidance of Construction Manager. (Griffith Watson, 2004, p.392) Materials are closely phased and delivered when assembled which to achieve just-in-time management in this project. Materials that are transported with heavy beloveds vehicles (HGVs) are expected to take place at night and that certain works may rush to be undertaken during this period so that it does non cause disruption to traffic flows, especially at peak times.2.2 storageStorage on site is erected to store materials, tools and equipments, spare parts for mechanic plant, and manufactured goods for incorporation in the work. (Griffith Watson, 2004, p.188) The distance amid storage and operation areas keeps short to reduce transportation needs in terms of time. woodland and steel reinforcement will be stored in a alter safe place and special store for fuel oils needed by the requirement of legislation. (Griffith Watson, 2004, p.189)2.3 Site OfficeA temporal site function will be provided on the site for management purposes and constitutionwork. These offices will be ho utilise in modular portable units. The size of site office will be calculated based on an example below size of it ExampleOffice for site agent and assistant plus an recompense for 3 visitors. Assume an internal average height of 2.400. Allow 3.7m2 marginal per person and 11.5m3 minimum per person. clean house ped-down area = 5 x 3.7 = 18.5m2Minimum volume = 5x 11.5 = 57.5m3Assume office width of 3.000 then minimum duration required is= 57.5/ (32.4) = 57.5/7.2 = 7.986 say 8.000Area check 38 = 24m2 which is 18.5m2 satisfactory (Chudley Greeno, 2008, p.94)2.4 planetary Site FacilitiesGeneral site facilities such as toilets, changing facilities, thunder mugteen, as well as shelter from inclement hold up will be provided on site. Adequate heating, lighting and ventilation are required in all toilet, washing, changing, and accommodation. The requirements of apiece facilities are specified the health and galosh decision maker (HSE) legislation (Griffith Watson, 2004, p.192). The location of all the facilities must be close together for easy access. The site accommodation will be located in the north corner of the site so to suit site access strategy. A row of single storey accommodation will be needed in the project. All the facilities creates build in portable.2.5 Site frontier F encing and HoardingA minimum height of 2.4m hoarding and close in will be erected around the perimeter of the site for protection (Griffith Howarth, 2001, p.252). Safety measures outlined by the Albert twist Code (ABC) must be followed. An out spatial relation signposting will be installed around the hoarding to enable the site to be more visible. Caution signs will also be displayed on fences and provide so that people will be aware when passing through and through the site. There will be a principle gate to the site along with pedestrian gates for access.2.6 Safety and SecurityFor both bail and safety reasons, site-bases warrantor presence will be provided during normal operative hours with a visiting patrol covering nights and week closing curtains to protect against theft and vandals of storage. Site-based security presence with a full 24 hours will be in place during the later stages of the construction works and fit out former to occupation (Griffith Watson, 2004, p. 391). All entry points will be clearly sign with appropriate warning nonice. Flood lightings with 500 watts in 7.50m high are installed as a measure of night security. (Chudley Greeno, 2008, p.91)Main Construction Work3.1 SubstructureConcrete percolatetease alkali will be used as the foundation of the houses. Foundation works include excavating, earthwork support, concreting and bricklaying of the elusion foundation. Trenches are excavated under the line of the walls and the soil at the bottom of the take advantagees is compacted. Rough sawn wood as strutting will be temporary support for the sides of excavation for strip foundation. At to the lowest degree 150mm of concrete is place at the foot of the trench with a concrete pump and brick walls are then built up to the damp p hood course (DPC) which will be at least 150mm above ground take. The DPC is slamded on a layer of mortar on each leaf of brick or block quarry foundation wall. (Osbourn Greeno, 1997, p.199) Th e depth of the strip foundation of 1m 1.2m is adequate to take in the soil playacting as the congenital foundation croupenot be affected by the bear and stake will be used to determine depth of concrete foundation (Osbourn Greeno, 1997, p.181 186). The strip foundation make of a continuous strip of concrete with 136 mix. Hardcore will be compacted using a vibrating plate or roller and the top of the hardcore is kept below the substructure block work so that the slab can be cast inside the walls. Concrete is protected with a tag of hessian or sand in cold weather and weather sheet of polythene in hot weather. (Marshall Worthing, 2000, p.57) The provision of damp proof membrane (DPM) for the entire area on top is between the over site concrete slab and it will be done on a bed of sand or ash of 12mm weightiness.3.2 Superstructure3.2.1 External WallCavity wall will be used in this project as it has good thermic insulation and weather rampart properties. Cement-lime mortar m ixes is used to ensure adequate bond of ties to wall. An adequate size of vertical spacing will be required for door and windows opening.3.2.2 ScaffoldingIn Mitchells Intro to Building (Osbourn Greeno, 1997, p.207) states that, As the work progress beyond a height where it is false for the bricklayer to lift materials from ground level, it will be necessary to erect hold to support raised working(a) platform.The scaffolding with aluminum alloy which connected by special fitting or couplings will be used to lay the upper floor wall.3.2.3 Doors and WindowsTemporary props will be erected until lintel construction has been complete. To connect the opening frames with the wall, rigid-angled galvanized mild steel lugs screwed to their side edges as the work proceeds. (Osbourn Greeno, 1997, p.203) DPC will be bedded when the work is carried out.3.2.4 intrinsic WallWork sequence will be similar to away wall but the internal wall is in single leaf. The class wall will be positioned and used to separate spaces within the building into rooms. Insulated plaster advance will be installed through the wall to gain thermal for the building. (EDP Energy, 2010)3.2.5 RoofPitch roof which erected by timberland trussed r subsequentlys space about 600mm at close centres to provide direct support for roof cladding and ceiling. (Osbourn Greeno, 1997, p.221) Install the ridge board on 2 end posts with temporary bracing and set it straight and level. Each rafters is nailed to the wall-plate which ready placed on a mortar bed on top of cavity block wall. (Osbourn Greeno, 1997, p.221) Prefabricated ladder fixed to the end trussed rafter. Fascia board fixed to the feet of rafter and barge board to the outer face of gable wall ladder. (Marshall Worthing, 2006 p.94) Install collar ties, purlin and bracing as needed for the rafters and ridge to hold on sagging over time. Timber trusses with bracing are manufactured off-site. remains tiles will be laid in continuously on the ti mber battens on sarking felt with 45 degree sloping of pitched roof.Finishes3.3.1 native Wall FinishesPlaster board will be utilise to internal wall as finishes with askew plaster method. Half-hour fire resistance will be provided when 5mm coat of wet plaster and 9.5mm thickness wet plaster applied on both sides of partition wall. A cracking which is used to provide additional line passage is left between the back of plaster board and the face of the wall. Then the gap will be connected to the cavity to the internal environment to allow air leakage. (Emmitt Gorse, 2005, p.535) Emulsion paint with piddle Based Paints Timber will be painted through the wall using the roller method. (Chudley Greeno, 2008, p.669)Skirting board with 19mm thickness will be nailed to the concrete fixing blocks at the base of walls after plastering is completed. (Emmitt Gorse, 2005, p.548-549)3.3.2 Floor FinishesSkim coats with mix of cement and water applied with a steel float to make smooth finis h on screed to allow carpet laid on it as floor finishes. Tackless strip placed around the entire perimeter rooms and shoot masonry screws into the strip and cut the strip by tin snip. Underlayment will be pour to hold the carpet padding. (Beach,1999-2010)3.3.3 Ceiling FinishesPlasterboard ceiling made with a core of gypsum sandwiched between face sheets of strong durable paper with 2.4 x 1.2 x 9.5 mm thick at centres and it fixed to joist by nailing. Then, 5mm single coat board finish plaster over stick grade undercoat. (Chudley Greeno, 2008, p.664)3.4 Existing ServicesExisting services drawings will be obtained for the site area, which are applicable to the complete development and must be referred to at all times. Prior to any mechanical excavation commencing, each suspect area will be hand dug to prolong the depth and location of any service and clearly marked on the surface. Extreme care will be taken when planning to work in these vicinities i.e. double check with CAT and G enny and follow above procedures.

Operatives have to wear safety helmet at all times on site. Besides, adequate safety footwear such as steel-toe-capped boots will be worn down by all company personnel. Casual shoes and trainers will not be permitted. All personnel are required to wear high visibility jacket or habit at all times. This clothing must be suitable for the working environment and prevailing weather conditions. Eye goggles, hearing and respiratory protection and protective clothing will be made available for use where required and according to on site conditions. Furthermore, gloves have to be worn all the time can trap hazardous chemical against skin.5.0 capability Environment fixA review of the potential environment impacts associated with construction works are being considered.
