5. Health & Safety Hazards
Before commencing any of the Fabrication and Installation of Wooden Doors, the team shall strictly follow woodwork Health Safety & Environment recommendations for handling and use of the materials and make sure that all involved working teams shall be aware of the same.
6. Procedure
- All the materials, which shall be used for the fabrication of doors, frames, and architraves shall be approved by QA/QC before starting manufacturing.
- Make sure that the timbers used for doors shall be free from unsound knots, dead knots, loose knots, and knotholes. The timbers should also be free from any type of decay and insect attack other than pinholes.
- All structural timber and softwood for permanent incorporation in the works shall be treated for protection from degradation by wood-destroying organisms.
- Protection against fire shall be by vacuum pressure process carried out following the manufacturer's recommendations.
- The certificate of treatment of timber following the specification shall be provided with every consignment of treated timber delivered.
- Treatment is to be carried out after all cutting and shaping have been completed. If subsequent cutting of the timber is unavoidable all freshly exposed surfaces shall receive a liberal application of the preservative recommended in the relevant treatment specification.
- The plywoods used shall be free from the bow, twist, and warp. The core in 3 pIy shall not be more than 60% of the total thickness.
- All plywoods thicker than 10 mm shall be made cl not less than 5 plies.
- Flush doors shall be plywood faced on both faces with hardwood piping to all edges.
- Openings for glazing in fire check flush doors shall be fitted with hardwood glazing beads on both sides minimum of 25 mm thick, fixed with brass screws and cups.
- Timber for carpentry shall be in continuous lengths in one piece wherever possible.
- All joints shall be glued and screwed or dowelled and in work that is exposed to the weather or internal wet areas they shall be glued with WBP Grade glue.
- All works shall be prepared, framed up, and put together at the earliest time possible and placed in a drying room for as long as practicable before being wedged or glued up.
- All joinery work shall be taken approval from QA/QC Engineer before being fixed in place.
- All the dimensions shall be verified on site before fabrication and installation.
- Exposed and semi-concealed joinery shall be planned and sanded to remove all machinery and other surface defects so that after application of the specified finish imperfections in manufacture will not be apparent.
- Arc traves, cover fillets and the like shall be accurately shaped to fit the contour of any irregular surface against which they are required to form a close connection.
- Where possible joinery for painting shall be primed before delivery to the site, and where this has not been carried out shall be primed as soon as possible after delivery, and approval shall be taken from QP Engineer.
- All joineries shall generally be secured with nails, masonry nails may be used to secure joinery timber directly to concrete or blockwork.
- Hardwood joinery and other timber which is polished or clear finished shall be secured with screws and with plastic plugs fixed to concrete or blockwork. The heads of the screws shall be counter sunk below the finished surface and covered in a matching timber pellet glued in and finished perfectly flush and smooth.
- On completion of fixing of doors/joineries, a final inspection shall be carried out and approval shall be obtained from the QA/QC engineer.
