It is advisable to take into account the strength of the construction after repair. For example, in situations where the timber is "load bearing", it may be appropriate to use timber splice in accordance with Repair Method Number 5. 2 Remove all decayed wood with the Window Care Profi using the Round Cutter. Continue to remove the decayed wood until sound timber is reached. The sound timber can be recognised by the high pitch sound of the Window Care Profi, it is generally of harder structure and uniform colour. 3 Lightly sand the surface of the timber using a medium grade abrasive paper. Check that the moisture content is below 18% using the Window Care Wood Condition Meter CS1. Apply hot air using a Hot Air Blower at 60-80°C. Avoid burning the timber fibres, this ensures good adhesion of Dry Flex RP. 4 Ensure that the adjoining paint system is removed up to 10mm from the vicinity of the repair. 5 Mix the required quantity of Dry Fix Wood Stabilizer in the correct ratio. Apply the Dry Fix well into the surface using a small brush. Wipe off any excess Dry Fix. Leave for 25-30 minutes before applying the Dry Flex RP. 6 Mix the Dry Flex RP thoroughly until a homogeneous "butter-like" mass is achieved. 7 Apply the Dry Flex RP using plastic modelling knives available from Window Care Systems Limited. For more complex repairs use perspex plates for "shuttering." 8 Apply hot air to the surface of Dry Flex RP for a few minutes. This is optional and is only recommended at times when wet weather can be anticipated or application at low temperatures. 9 Ensure that the Dry Flex RP is completely dry (normally 24 hours are required at 20°C) and longer periods when applied under low temperature conditions. 10 Use the Window Care Scraper to remove 'excess' cured Dry Flex RP. 11 Sand the repaired areas lightly to achieve an even, smooth surface before painting with an alkyd or water-based paint system. * Check with the Specifier, if, Window Care DRY PIN is to be used. * Where applicable, DRY PIN should be applied as illustrated in the "Systems" Brochure. A test application is always advisable before commencing work. Ringley Chartered Surveyors Job Number: b176931b-0f20-4f79-8d43-c365df4aced7.xls Materials Workmanship Window Care System OPTION B – REPAIR USING PART TIMBER SPLICE REPLACEMENT. Cut out the decayed wood at an angle of 75° until the sound timber is reached. The timber may be cut using a saw, chisel or Window Care Profi. The strength of the construction after repair should be taken into account. In situations where the timber is load bearing", the use of steel reinforced rods may be necessary. For normal repair by "splicing in timber", follow the procedure below: 1 Prepare the new timber splice (moisture content <18%) in such a way that there is a seam/gap of at least 4mm between the contact areas, use the Window Care Wood Condition Meter CS1 to measure the moisture content. 2 If the contact areas of the existing wood have a moisture content of over 18%, blow dry the affected area using a hot air blower at a temperature of 60-80°C. Strip the existing paint finish up to at least10mm from the joint on existing timber. Ensure that the new timber is left clean and un-primed during the fixing process. 3 Apply Window Care Dry Fix Wood Stabilizer to the end grain of the existing timber and the new timber splice using a brush. Work the Dry Fix well into the surface. Leave for about 25-30 minutes. Apply Dry Flex RP on all areas of contact (already treated with Dry Fix). Use a 4mm "space" at the joint and secure the new timber splice in position using a perspex fixing plate. Fill the "joint" with Dry Flex RP and smooth the surface using a plastic knife. Avoid any surface irregularities. 4 Allow at least 24 hours drying at 20°C before any surface sanding and subsequent painting. At lower temperatures allow a longer period of time for Dry Flex RP to dry. The fixing plate can be removed when the Dry Flex RP has dried completely. Use the Window Care Scraper to remove 'excess' cured Dry Flex RP. Sand the Dry Flex RP lightly. Remove dust/dirt before painting with an alkyd or water-based paint system. * Check with the Specifier, if, Window Care Dry Pin is to be used. * Where applicable, DRY PIN should be applied as illustrated in the "Systems" Brochure.

All the terms and conditions of the Licence must be met, including the payment of the deposit notified before the structure is erected. Applications should be made to the Highways Licensing Section. Great care must be taken when erecting or dismantling scaffolding on or near the public highway. The scaffolding contractor and the main contractor share responsibility for ensuring that work is carried out safely. All too often accidents involving members of the public and their property are caused by bad working practices. Scaffolding must comply with the following conditions After the scaffolding has been erected, any diagonal cross-bracing used at ground level must be removed at once to allow unobstructed pedestrian access. A width of at least 1.8 metres and a headroom clearance of at least 2.44 metres are required for pedestrians to pass, unless other arrangements are agreed by the Local Authority. While a scaffold is being erected, signs should be prominently displayed saying “Scaffold is incomplete”. Vertical scaffold poles erected on the pavement must not be closer than 0.45 metres to the kerb edge, unless other arrangements have been agreed with Local Authority. Scaffolding that projects beyond the kerb edge must have at least 4.88 metres clearance above the surface of the carriageway. Where agreement has been obtained to erect the scaffold nearer than 0.45 metres to the kerb edge, baulk timbers 300mm x 300mm must be placed on the carriageway for the full length of the scaffolding. These timbers must be painted red and white and fitted with red bulkhead lights at 3 metre intervals. Continuous timber or sole plates may not be placed on the highway. Scaffolding must be lit from half an hour after sunset to half an hour before sunrise. On the inside of the structure, white bulkhead lights must be set at each end of the structure 2.44 metres high and at 3 metre intervals. Similarly, on the outside of the structure red bulkhead lights must be set at each end of the structure 2.44 metres high and at 3 metre intervals high and at 3 metre intervals. The diagram overleaf indicates the Local Authority‟s general requirements. Where a scaffold is longer than 3 metres, the Local Authority will insist that you provide “escape routes” for pedestrians at 3 metre intervals. The Crime Prevention Officer at the local Metropolitan Police Station may request more onerous requirements. You must obtain approval in principle for any such structure before a licence is issued. Standards must be painted white up to a height of at least 2.44 metres. Any couplings below 2.44 metres must be fixed so that any projection, or threaded or clamp fixing, is on the opposite side to pedestrians. Horizontal scaffold poles, such as handrails, must be fitted with plastic end caps or otherwise made safe, as directed by the Local Authority. Scaffolding, scaffold boards, temporary roofs and sheeted scaffolds must be properly secured to resist high winds. Sheeted scaffolds are particularly vulnerable to wind damage from the “sail effect”. Scaffolding must not obstruct access by emergency services vehicles. If there is any risk of falling material injuring passing pedestrians or hitting vehicles, you must erect a protective scaffold fan. For instance, a scaffold fan is needed when operating cradles or carrying out masonry work. Fans or screens must be wide enough to provide complete protection to the public, and to prevent material of any kind from falling onto the public highway. Ringley Chartered Surveyors Appendix Job Number: b176931b-0f20-4f79-8d43-c365df4aced7.xls Scaffolding, Rubbish Shutes Gantry Fans that project to within 0.45 metres of the kerb edge must have at least 2.44 metres clearance above the surface of the public highway. Fans projecting beyond this line must have at least 4.88 metres clearance above the surface of the carriageway. CLEANING BUILDINGS When cleaning the exterior of buildings, ensure that no cleaning materials, sand, grit, or water fall onto the public highway. Water spray must be confined to the face of the building and be channelled across the footway. The scaffold to the building shall be completely encased in plastic sheeting, which must be securely tied. Stone cleaning operations may be restricted to times outside normal working hours. Contact the 24 Hour Noise and Dust team to obtain permission. We also advise you to consult the Local Authority‟s Development Division before cleaning any listed building. GANTRIES, HOISTS AND SITE HUTS Before erecting any gantry or hoist no the public highway you need to get permission from the Local Authority and be issued with a licence. All the terms and conditions of the licence must be met, including the payment of the deposit notified, before the structure is erected. Applications should be submitted to the Highways Licensing Section. Permission will not be granted for the erection of gantries for storing materials or as working platforms for hoists and associated equipment if there is any practical alternative on site. The Local Authority does not allow site huts for offices to be put on gantries on or over any part of the public highway. Offices must be contained within the boundaries of your site. If there is not enough space on site for accommodation, you should use alternatives such as rented office space. Only in exceptional circumstances will temporary accommodation on a gantry be allowed, and then only for welfare and messing facilities. Again, you should apply to the Highways Licensing Section. Gantries must comply with the following requirements: Gantry platforms must be double-boarded with polythene sheeting between each layer and set at a minimum headroom clearance of 2.44 metres from the surface of the doorway. The outer standards or columns of the gantry must be encased in plywood up to 1.22 metres high and boxed in at the top. Once the gantry has been erected, any bracing etc used at ground level, or less than 2.44 metres above the footway, must be removed to allow safe passage by pedestrians. Any gantry that projects beyond the kerb edge must have at least 4.88 metres clearance above the surface of the carriageway. Gantries must be lit from half an hour before sunrise. On the inside of the structure, white bulkhead lights must be set each end of the structure 2.44 metres high and at 3 metre intervals. Similarly, on the outside of the structure, red bulkhead lights must be set at each and at 3 metre intervals. The following diagram indicates the Local Authoritys‟ general requirements: Mechanical or platform hoists must not descend onto, or operate from the public highway. Permission will only be granted for hoists to be operated only from gantry platforms at first floor level or above. Gin wheels and other forms of rope or cable must be used only on the outside of scaffolding, and then only when the scaffolding reaches the kerb edge. In these circumstances building materials must be hoisted from the carriageway and are never permitted over the footway. Any other kind of hoisting must be carried out on private land. Ringley Chartered Surveyors Appendix Job Number: b176931b-0f20-4f79-8d43-c365df4aced7.xls Scaffolding, Rubbish Shutes Gantry The hoisting of hot tar buckets is not permitted on the road except from a gantry platform, and is never permitted from the footway. RUBBISH CHUTES To protect passing pedestrians, rubbish chutes can be used only when fixed to a supporting scaffold gantry which has a minimum clearance of 2.44 metres over the footway. To stop dust or debris escaping, chutes must be completely enclosed and covered at the discharge end, (which includes lorries and skips), to stop dust or debris escaping and must be moved aside when not in use. They must be fixed or tied to the supporting gantry or scaffold. HOARDINGS Before erecting a hoarding on the public highway you need to get permission from the Local Authority and be issued with a licence. All the terms and conditions of the licence must be met, including payment of the deposit notified before structure is erected. Application should be made to the Highways Licensing Section. A hoarding may affect access to gullies, manhole covers, fire hydrants, public lighting, parking meters or residents‟ parking bays, access covers, apparatus or services belonging to statutory undertakers or to the local authority. Before your application for a licence is considered, you must obtain permission from all parties whose services may be affected. Permission is also required if you have to resite or remove street furniture such as light columns. Apply to Westminster Highways Consultancy Service. If a lamp column cannot be repositioned, you may have to provide alternative lighting fixed to the satisfaction of the Local Authority. Hoardings must comply with the following requirements: They must be not less than 2.44 metres in height and should be constructed of smooth, close-boarded timber. Corrugated sheeting must not be used. For safety reasons, the corners of the hoarding must be splayed where vehicles or pedestrians pass around them. Hoardings must be painted in a uniform style. Members of the Considerate Builders Scheme are encouraged to paint their hoardings in the scheme‟s colours, which are green and blue on a white background. British Standard Paint references and design guidelines are available from the Considerate Builders Office. Murals, company logos and hoardings decorated in other ways may require advertisement consent from the Local Authority‟s Development Division. Hoardings must be lit from half an hour after sunset to half an hour before sunrise. Bulkhead lights should be fixed at the top of the hoarding at each end of the structure and at 3 metre intervals in between. Any access points in the hoarding must not open outwards over the public highway. No advertisements may be placed on any hoardings. Special attention should be paid to any contractor‟s signs and logos placed on hoardings to ensure that they comply with the Town and Country Planning (Control of Advertisements) Regulations 1992. Any fly posting or graffiti on hoardings must be removed immediately by the licence holder. It is also the licence holder‟s responsibility to ensure that no structures associated with the works give rise to complaints, and that they are maintained to the satisfaction of the Local Authority. You can get advice on anti-fly posting measures from the Street Patrols Service of the Environmental Protection Group. If a platform or handrail is needed, this must be maintained to the satisfaction of the Local Authority. Hoardings must not obstruct access by emergency service vehicles. Hoardings should be properly secured to resist high winds.
