What needs to be clarified
Check whether the proposed work is technically necessary and recalculate restoration without counting included components twice, retaining substantiated repair alternatives.
Materials to prepare
- Chair with original hinges and photographs of damaged joints
- Itemised estimate listing quantities and labour operations
- Assembly diagram and offers for compatible replacement assemblies
What to compare
Compare play, deformation and hole condition with the proposed replacement. Use part numbers to establish frame contents and whether fasteners can be fitted separately. Separate dismantling, replacement and reassembly to identify repeated operations. Calculate using supplied, supported rates, showing delivery and work whose necessity remains unconfirmed after inspection separately.
Possible outcome of the analysis
A checked work schedule may compare technically feasible repair options, identifying duplicate charges, assumptions and items needing further confirmation of compatibility or scope.
Limits of the conclusions
The cheapest component may be unsuitable for a loaded joint. Recalculation does not guarantee repair safety; the restored chair’s load capacity needs a separate appropriate structural test.
