Comprehensive and Detailed Explanation:

Under FIDIC Red Book 1999, the Performance Security (or Performance Guarantee) is held to ensure the Contractor’s performance during the defects liability period. The security is typically released only after the Employer issues the Performance Certificate, which confirms the completion of defects liability obligations and that the Contractor has fulfilled the contract.

The contract commonly specifies a fixed period (often 21 days) within which the Employer must return the Performance Security after issuance of the Performance Certificate (Option D). The Taking-Over Certificate (Options A and C) marks substantial completion but does not end the Contractor’s obligations for defects.

Comprehensive and Detailed Explanation:

Under FIDIC Red Book 1999, price adjustments after the Time for Completion are based on the indices or prices applicable on the date 49 days before the expiry of the Time for Completion, not the current index. This prevents the Contractor from benefiting from price fluctuations after the contract period.

This clause ensures fairness by locking the price basis as of a fixed reference date, protecting the Employer from increased costs due to delays.

Y is not correct. The Contractor’s obligation to commence works depends on the Commencement Date notification as per the contract. If the Employer requests commencement on the 14th day after signing, and the contract allows or the Engineer has not yet notified otherwise, the Contractor should comply unless formally instructed otherwise.

Delaying work beyond the contractual or Employer’s instruction without valid cause may be considered breach of contract and could lead to claims against the Contractor.

According to FIDIC Red and Yellow Books (both 1999 and 2017 editions), the advance payment guarantee amount may be progressively reduced as the Contractor repays the advance payment through deductions from interim payment certificates. This means the guarantee is reduced as per amounts repaid, not only upon full repayment.

Option D is correct: The guarantee reduces as partial repayments are certified in Payment Certificates.

Option C is incorrect because the reduction happens gradually, not only after full repayment.

Options A and B do not directly relate to the reduction mechanism of the advance payment guarantee.
