1. TITLE

Method Statement for Installation of Insulated Roof & Wall Cladding

2. SCOPE OF WORK

2.1. General Description

Roof and wall sheeting installation method statement describes the procedures of work which will form the buildings that constitutes this project.

2.2. Plant&Equipment

A- Lifting Equipment- 50 ton mobile crane (2 No.)- 25 ton mobile crane (4 No.)- 3 ton telescopic boom loader- Scaffoldings- Man lift

B-Electrical equipment- Generator - Drill (110 volts)- Screw gun - Electrical nibbler- Industrial multi sockets- Cutting Machines

2.3. Materials

2.3.1 Cladding materials

Roof and wall sheets (0.8mm thk aluminum outer skin w/ 45/250 trapezoidal profile & 0.5mm thk. inner skin w/ 50mm thk. Core Polyurethane foam)

Fasteners/Aluminum rivets (4.8mm dia.) Mastic sealant (12x3 mm Polybutyl)Flashing materialExternal – 1.0mm. Gauge plain aluminum sheetInternal – 0.50mm. Gauge plain stucco embossed aluminum sheet




2.4. Site Planning & Preparation

2.4.1 Transportation:

Articulated Lorries are generally used for delivery and it is normally the responsibility of the recipient to arrange the provision of suitable equipment for off-loading. A crane with slings and spreader bar or a forklift truck will usually be required. Composite panels sheet may be delivered by curtain sided vehicles to afford optimum protection. Forklift trucks should be used for off-loading.

Each day prior to commencement of work lift plan would be prepared by safety personnel and shall be exercise during similar activity at site.

2.4.2 Handling:

Compared with panels manufactured from other material, cladding composed of aluminum with rigid polyurethane foam core is lightweight having density of about 35kg/m3, enabling long sheets to be handled with ease and with a minimum of operatives.

If a crane is used for unloading, at least two slings should be used – single sling should NEVER be used.

Unprotected chains, bars or fork trucks will damage the sheet, particularly at the edges, and should be avoided. Always ensure that packs of sheet are securely banded before lifting.

When handling individual sheets, care should be taken not to damage edges or corners, as they may interfere with sheet laying operations and, prevent the achievement of a weatherproof seal. Insulated sheet should be lifted from beneath the bonded insulation and never by the aluminum alone as this may cause the bond between the sheet and the insulation to break.

Other way of lifting by fork lift, the panels should be placed on the fork at equal length side by side in order to balance the weight to avoid the possible drop – off of the said materials and to ensure the maximum loading capacity of the fork lift must be attained.




2.4.3 Storage:

Ideally, cladding should be stored under cover in the original packing and in a dry, well-ventilated position.

Even crated material should be stored under cover, to protect it from the weather.

It is important to keep the sheets well away from building operations where they could be contaminated with lime and cement, which would cause staining. If they are stored for more than a short time out of their packaging, precautions should be taken to see that moisture is not allowed to percolate between them.

If sheets are stored in the open they should be kept off the ground and covered with polythene sheeting. Care must be taken to ensure that the timber battens used in building the stack are aligned and keep the tarpaulin off the metal. Wet tarpaulins in contact with bare sheet should be avoided. When covering sheets with tarpaulins it is important to ensure there is adequate ventilation to prevent condensation occurring.

Stacks of loose sheets should not be built too high or the bottom sheets may spread.

2.4.4 Project Site Condition:

Work would be proceed only when/depending on actual site condition and weather forecast so that damages might occurred would be prevented.

2.4.5 Field Measurements:

Site Cladding Engineer is in-charge in the overall measurements with the assistance of a foreman who would strictly check in order to ensure locations of structural members, openings etc. would be traced out in accordance to the approved drawings.

2.4.6 Coordination:

Before the commencement of cladding activities, any other trades such as MEP, related subcontractors and main construction team would conduct a coordination meeting on regular basis in order to facilitate/assist the activity at site in smooth progress and to complete the project without any mistakes, nonconformity being made.




2.4.7 General

2.4.7.1 Safety Roles and Responsibilities

HSE officer will be involved in all safety measures related to HEC scope of works. Environmental officer is checking for oil spill and housekeeping.

It is assured that the fixing team will have relevant electrical equipment and hand tools to adequately perform the installation work.

2.4.7.2 Pre Erection Checks

2.4.7.2.1 MATERIALS:

Materials arriving on site should be checked immediately for quantity, type and dimension against appropriate Advise Notes. Particular care should be taken to ensure the safe receipt of small parcels containing fasteners, mastic etc. When signing Advise Notes for sack or bundles etc, it is only necessary to check the type of contents and number of sacks, bundles etc.

2.4.7.2.2 ERECTION DRAWINGS:

Prior to commencing installation, visual checking would be carried out for the secondary steelwork. Any obvious problems should be pointed out immediately to allow remedial work to be undertaken before the cladding fixer begins work. Fixer must ensure that all relevant drawings and fixing instructions are available. These should be consulted and understood before commencing erection drawings with reference numbers;

CFS-1000-208-VB-8900-50015 to 50023, 50080 to 50081, 50107

CRW-1000-208-VB-8200-50010 to 50014, 50082

XRF1-1000-208-VB-8200-50035 to 50040, 50104

XRF2-1000-208-VB-8200-50095 to 50101

1000-208-VB-8200-50110 to 50121, 50106




Drawings, fixing instructions and Advice Notes, together should be kept in safe place on site.

2.4.7.2.3 BUILDING FRAMEWORK:

The frame of the building must be checked for the following before commencing installation. The frames would be checked by using man lift to ensure horizontally and vertically wise the frame is in true line and plumbed respectively.

Purlins and rails are at correct spacing as shown on erection drawings and are all in one plane.

Overall dimensions of roof or wall correspond with those shown on erection drawings.

Corner of roof are square and wall steelwork is perpendicular.

No protrusions occur on the face of the steel work, such as bolt heads, rivet heads, splice plates etc.

Work carried out by preceding trades (gutters, glazing, steelwork, painting etc.) is completed.

Where dwarf walls occur, they are of correct height and positioned as shown in the erection drawings.

Details and positions of openings, i.e. doors, windows etc are as shown on erection drawings.

IMPORTANT: Ladder would be securely fixed, inspected and tagged before the access lifting points.

2.4.7.2.4 SEPARATING SHEETS:

Care must be taken when separating items in packs, to ensure that damage does not occur to the coating. They should be separated with a series of jerking movements, rather than one continuous movement. During the hot weather, it is best to separate protected metal components early in the morning before the sun has heated the packs.




2.5 Work Methodology

2.5.1 Roof Cladding:

The first line of installation for roof cladding would be at end wall laid along the truss/rafter and must be carefully aligned, fixed temporarily with 115mm. long, 6.3mm diameter self tapping stainless steel fasteners with neoprene washers and PVC color cap. Fixers would use 110-volts power tools for fixing and working from a manlift.

First sheet of the first line would be lifted by crane to be laid out starting from the eaves held to 50-50-50mm Z- angle spacer fastened with 25mm. long 6.3mm. dia. Self tapping stainless steel, the second and third sheet towards the ridge then it can be finally fastened prior to proceed the succeeding line but before fixing of any fasteners sheets must be correctly aligned at right angles in relation to ridge and eaves line of building.

2.5.2 Ridge:

Crimped ridge would be laid after the installation of roof sheets at each gable.

Flashing of 400 mm. width would be fixed at inner skin of roof panel by blind rivets at 400mm. center to center. Flashing when securely fixed 50 mm. thick polyurethane insulation would be place on it then a 3x9mm polybutyl sealant tape would be placed on sheet/outer skin of panel at three (3) rows side by side from the edge of the panel.

Once the preceding works has been completed a 600mm. width crimped ridge would be fixed to panel and fastened with blind rivets at distance of 250mm. center to center.

The ridge will be installed as the roof sheets are laid ensuring all holes are covered.

2.5.3. Wall Cladding:

Wall cladding installation shall commence after the full completion of the roofing installation. But before works proceed deep check for the alignment of the rails, ensure that rail is in true line and plumbed and must be done by cladding engineer assisted with foreman.




2.5.4. Curved Sheet / Eaves:

Curved sheet would be laid in position temporarily in line with the wall & steel work. Ensure sheet secure in position.

2.5.5. Flashing:

All corners such as roof end wall, wall, and openings shall be covered with 1.0mm. Gauge plain aluminum sheet stitched with 4.8mm dia. by 11.5mm. Long rivets spaced at 350mm center to center. Details for each corresponding length and width of flashing can be found on approved shop drawings reference written in the QA/QC table below.

2.5.6 Inspection:

2.5.6.1 Prior to Installation of Roof and Wall Cladding, ensure IRF for steel erection is already approved and no NCR is open.

2.5.6.2 Each 9 bays when works completed, Inspection request would be submitted to the Client for approval prior to start of the succeeding bays.
