- Prior to commencing, the plotter operator is to check all cutting patterns are within cutting area of table and do not overlap each other.
- Any queries that arise must be answered before marking and cutting begins.
- All patterns are to be cut by the plotter unless otherwise discussed
- Prior to commencing, the plotter operator is to check all cutting patterns are within cutting area of table and do not overlap each other.
- Any queries that arise must be answered before marking and cutting begins.
- All patterns are to be cut by the plotter unless otherwise discussed.
- After plotting, a final check of panels will be performed by the plotter operator. Operator to check that panel numbers, fold lines etc are present on all panels.
- All panel marks shall be made with a GREEN pen only which can be removed with white spirit and clean cloth.
- When plotting is complete the Operator is to complete SUPPLIER – Plotting sheet and sign off his work.
- A properly performed high frequency weld shall be defined as one which when peeled apart, removes the Teflon or PVC coating from one or both sides completely. This is referred to as “delamination” test.
- All weld surfaces must be clean and free of obstruction prior to welding. Ensure the welder bottom plate is covered with barrier paper prior welding.
- All test welds are to be welded out of the fabric being used for the project. The test weld samples for the completed job shall be labeled and placed with project detail sheets. These samples will be stored for future reference.
- Any errors in welding shall be immediately reported to Production Supervisor
- Overlapping panels must be properly lined up and even tension placed on either panel. Uneven tension will cause wrinkling in the fabric once it has been welded and this will not be acceptable.
- Use the maximum size welding bar suitable for the project as to minimize the amount of welds required. The welding bar should be checked for surface quality and straightness before use. Report any faults to Supervisor.
- Test welds to be performed before commencing welding on project fabric.
- Welds should have no excessive PTFE / PVC visible outside the weld width.
- When welding is complete the Operator is to complete SUPPLIER – Fabrication Worksheet and the Supervisor is to check and sign off this work.
- Doublers are to be welded with small plates “Floaters” using the size that minimizes the amount of welds per doubler according to the size of doubler.
- All hardware including cables, membrane plates, nuts and bolts etc, shall be made to the project specifications and design details.
- Holes in fabric for membrane plates must be punched in the factory using the membrane plate itself as template. Provided this will not pose any risk to the safe packing and transport of fabric panels to site, membrane plates are to be fitted in the factory to ensure no misfits on site.
- As far as is practicable, also bale rings are to be fitted inside the factory to ensure no misfit problems on site.
- Fabric Supervisor Worksheet, the following activities should always show a record of the date work was performed, the Operator who performed the work and the Supervisor who checked the work:
- Fabric Inspection
- Plotting
- Test welds
- Welding
- Sewing
- Marking Out
- Cutting
- Punching
- Cleaning
- Folding/Packing
The above record sheets are provided to factory staff prior commencement of each project. SUPPLIER Plotting Sheet and SUPPLIER Fabrication Worksheet must be filled throughout each process and must be kept in the project file during fabrication. These records are to be kept in the appropriate project file and archived for future reference on completion.
INSTALLATION OF FABRIC ROOF OVER CAFETERIA
- Ensure that Material submittals and subcontractor are approved by the COMPANY.
- Ensure that shop drawings showing details of fabrication, assembly, installation and fixing of specific items or components are submitted and approved by the COMPANY.
- Installation should be done as per the manufacturer recommendations.
- Check that all necessary clearances and permits are available.
- The work areas must be barricaded with warning tapes before start of work.
- The work areas must be clear from un-wanted material and other obstructions.
- All the survey and setting out works are complete and inspected by the COMPANY. All levels / locations for base plates and/or other fixings are correct as per approved shop drawings.
WORKMANSHIP
- A typical installation sequence shall be as follows:
- The anchor bolts that hold the steel structure will be done first. These are either cast-in RCC footings or site-fixed into RCC walls/slabs/columns using HILTI chemicals.
- The structural steel framing (columns and beams) shall be then fixed and made plumb / square. All bolts will be tightened up.
- The factory-packed fabric panels will be positioned on a clean surface area over a clean ground sheet. Each fabric panel will be carefully opened and its accessories (viz. membrane plates) bolted to it.
- Fabric panels will be carefully lifted up and connected in position as per the sequence. Great care shall be exerted to avoid any damage to the fabric during installation.
- Fabric panels will be then tensioned as per approved procedures to the shape intended.
Finally, the completed structure will be cleaned up and any paint scratches shall be touched up to Client satisfaction.
