DORMER CAPS AND CORRUGATED IRON REPLACEMENT

AKAROA BODY CORPORATE APARTMENT #49 DORMER WINDOWS & ROOF REPAIRS REPLACE 2 off DORMER WINDOW CAPS & SIDES REPLACE 2 off LONG RUN SHEETS OF CORRUGATED IRON Replace current ‘expired Butynol dormer claddings’ with preformed, welded and baked enamel Zincalume caps sourced from a known supplier with past experience of supplying exactly the same product. The capping flashings will be integral which means a complete Dormer Cap is replaced in 3 separate parts only ie a top and two sides. Details of the caps and the approved supplier will be provided by Jacques Body Corporate. Underneath the Butynol there is a layer of 20mm chipboard of low quality often called ‘Weetbix’. It needs to be replaced with Marine Ply or better and then sealed with a suitable moisture barrier material. The existing (1982) heat insulation inside the dormer should be replaced. Underneath the chipboard is a traditional Rimu 4x2 frame which will be in good condition but it is too hard to penetrate with nails and needs to be pre-drilled and screwed wherever possible. The Dormers are part of a corrugated iron roof (imperial dimensions) painted in 2017. There are 2 sheets of iron that need to be replaced with roofing screws, one each side of the West side dormer. They will need to be painted prior to installation. The roof is a 45 deg pitch over a second level apartment and will require scaffolding to approx minimum 5m. Mobile ‘H style units’ will be compatible with the area. There is a local set available for hire at low rates. It is expected that the contractor will supply all materials, equipment and transportation for the job to onsite except the dormer caps which will be ordered by the contractor from the experienced supplier and paid for by the body corporate. The builder must also provide:- 1. A copy of their Occupational Health and Safety plan for the job. 2. A copy of their public liability insurance certificate. 3. A copy of any builder’s accreditation certificates. 4. Suitable scaffolding (H frame is acceptable). 5. Required safety equipment. 6. Disposal of removed materials from the work area. 7. Weather protection for any ‘opened’ parts of the roof under repair. 8. 3 years warranty for the work completed and be responsible for any defects and/or leaks. TIME FRAME:-Autumn or Spring 2020 SUGGESTED PROCESS PLAN (Based on our past experience) 1. Advise local project manager of arrival, erect scaffold and safety equipment and assess the job ahead. 2. Measure the dimensions of the dormers and decide the sizes that will be submitted to the capping supplier. 3. Measure the dimensions of the new iron required and decide the sizes to be submitted to the iron supplier. 4. Submit the sizes of all components to the suppliers asap via email (must be in writing) with a copy for the Body Corporate. 5. Remove butynol and chipboard from the dormers and prepare to remove the old iron. Ensure the building is weather tight and safe for all concerned. 6. Prepare the new iron and caps for fitting. The 2 new iron sheets need to be painted to match the existing colour. 7. Recap the East dormer. 8. Partially lift the two sheets of old iron around the West dormer and fit the dormer cap. 9. Remove the old iron and replace with new. 10. Ensure site is clean and rubbish has been removed. 11. Water test the roof and dormers with the onsite fire hose. 12.
