Comprehensive and Detailed Explanation:

According to the FIDIC Silver Book, 1999 Edition (The Conditions of Contract for EPC/Turnkey Projects), the Contractor is required under Sub-Clause 8.3 (“Programme”) to submit a time programme that illustrates the sequence and timing of the works, including milestones and key events. The intended order of the works (Option A), sequence and timing of inspections and tests (Option B), and review periods (Option D) related to contract management processes such as approval of design or submissions (Sub-Clause 5.2) are integral to effective scheduling and coordination.

However,remedial work instructed under Sub-Clause 7.6, which concerns remedying defects or damage, is generally not part of the initial or revised programme. Instead, remedial works are typically handled as separate tasks or incorporated into specific defect liability or rectification schedules after the main programme has been executed. Such remedial works arise from defects liability obligations and do not belong to the original or revised time programme used to plan the main construction phases.

This distinction is important because the programme reflects planned works execution, whereas remedial work is reactive and may be scheduled separately under defects liability clauses or final project close-out arrangements.
