The document discusses the procedure and essential elements involved in preparing a final account. It defines key terms like final account, provisional sums, and prime cost sums. The procedure for final account involves the contractor submitting documents within 6 months of completion for the architect to complete the account within another 6 months. Adjustments must be made for variations, remeasuring provisional quantities, omitting unused provisional/prime cost sums, and adding back nominated subcontractors' accounts. Implications of omitting works from the bill of quantities and not allowing them as provisional sums are discussed from the client and contractor perspectives.
