2. Method of working.

Operation

2.1 Capital Construction Limited will obtain authorisation from the Clientand the adjacent hospital (The Wellington Hospital), to commencework on site and will confirm the working areas, welfare arrangements,first aid and emergency arrangements, storage & temporary laydownlocations and ensure that this information is communicated by way of

the site safety induction and daily task briefings.

Operatives will be required to provide details of training andCSCS/CISRS accreditation details at the induction together with asigned copy of the method statement/risk assessment register.

2.2 Following the arrival of the scaffolding materials the delivery shall be

offloaded initially using a vehicle mounted HIAB (in the interest ofavoiding unnecessary manual handling of materials and working atheight) and fully certified associated certified lifting accessoriestogether with a trained operator and competent personnel to an areaspecifically dedicated to the laydown of the scaffolding materials withinthe perimeter of the site.

All deliveries shall be directed to report to the Site Manager or


5/24

2.4 Once all necessary barrier protection and hazard warning signage has

been erected/prominently displayed around any working areas, ourskilled and competent operatives shall confirm the sequencing of workand shall confirm that the area has been cleared of any pre-existingservices or other obstructions that may impinge upon the erection ofthe scaffold.

2.5 Once satisfied that the areas have been made ready and that a suitable

level foundation for the scaffold is available, our competent (CISRS 1 &2 Card carrying operatives shall agree the sequence of erection andensure that any necessary permissions have been obtained from thehospital for the purpose of providing a temporary safe means of accessinto the existing ground floor area of the main house.

2.6 The initial phase of these operations will be to provide a scaffold

platform and ladder access into the existing ground floor of No. 8Wellington Place. Any such access will be subject to prior approvalfrom the Hospital as the platform position will encroach onto theirproperty by approximately 1.2 metres (see photo 1.0 below).

2.9 The 2nd phase of the operation will be to manually transport thenecessary components using a Ginny wheel and rope, where necessary

to the ground floor for the purpose of erecting an internal tower andcantilevered access platform and ladder access into the basement.

2.10 The scaffold design shall be checked for the purpose of establishingthe correct bay widths and setting out details for the standards, beforesiting the sole boards, upon which the standards shall be founded,using the footplates and locating shank to accurately position the

standard central to the sole board.

2.11 The standards shall then be set out and jointed using right angled loadbearing fittings to join the ledgers and transoms, checking the tubesfor alignment, plumb and level so as to ensure adherence to the designprovided or recognised standard configuration in accordance withBSEN12811 and TG20:13 i.e. maximum and minimum lift heights, bay

widths, and transom centres Etc.

2.12 The scaffolders shall ensure that the harness and lanyard issued toeach individual is worn at all times and scaffolders shall be madeaware that they must ensure that they are clipped on to the nearestavailable suitable anchor point when working at a height likely to causeinjury in the event of a fall, in accordance with SG04.

2.16 Tubes ends shall be capped to reduce the risk of impalement; cuts and

abrasions, standards projecting through the platform must eitherextend a minimum of 950mm above the platform or be cut off flush tothe working platform level, so as to reduce the risks associated withtrips and falls.

2.17 Gaps within the platform boards shall be closed using either anadditional ledger tube or ScaffGap proprietary void closer, (see

below) in the interest of reducing the risk of any materials, fittings etcfalling through any gaps. Notching of platform boards shall beprohibited.

3. Sequence of operations.

3.1 Delivery of materials and equipment

Arrangements will be made to ensure that adequate time allowance isavailable for the movement and set down of materials. All deliveriesmust be pre-booked at least 48hrs in advance.

In addition, Capital Construction Limited shall ensure that any planned

deliveries are notified to the Site Manager as soon as reasonablypracticable, so as to facilitate good communication between all partiesi.e. Hospital Staff/Personnel and neighbouring properties, therebyreducing the potential for impacting upon other residents, theneighbouring construction project and other traffic, in particular servicecontractors to the Hospital and Emergency Services.

Materials will be brought to the work site by a suitable sign written,long wheel base, flat bed, commercial vehicle and will report to the SiteManager before being directed to the designated loading/unloadingareas.

The attending delivery vehicle shall incorporate edge protection aroundthe bed of the trailer in the interest of reducing the risk of falls from

9/24

A restriction will be placed on the amount of materials placed in onearea at any one time on site to ensure that there is no overloading of

the existing ground or rc slab and that trip hazards are reduced withaccess / egress routes remaining clear.

In particular, the areas will be carefully monitored for any loose fittingsrolling stock or off-cuts, any such materials or debris will be clearedimmediately and securely stored within a stillage or Hessian sack forsubsequent disposal.

All materials will be placed to as close to the work area as possible(given the space constraints), in the prevention of manual handlingtasks.

3.2 Preparation.

Others within the work area will be advised of the works to beundertaken in the area and of any risks present e.g. slippery surfaces,uneven ground conditions or unstable ground conditions etc. Whereexcavation works are in progress, signage will be displayed uponbarriers warning of dangers e.g. Danger Scaffolding in Progress, NoUnauthorised Admittance etc.
