Why Backdated Baseline Schedules Are Not Acceptable: FIDIC, PMI, and AACE Guidelines Explained
In project environments governed by international best practices, a contractor's refusal to submit a baseline schedule updated to reflect 14 months of actual progress is a serious concern. From a contract management and project controls perspective, this approach undermines effective oversight and jeopardizes transparency.
Submitting a backdated, non-updated baseline after 14 months is non-compliant with FIDIC Sub-Clause 8.3, fails to meet PMI’s schedule management standards, and does not align with AACE RP 29R-03 practices. For accurate project control, transparency, and fair claim evaluation, the contractor must be required to submit an updated, data-driven baseline programme. This ensures both contractual and technical compliance while protecting the interests of all project stakeholders.
