Why does missing the implicit activities lead to a misleading schedule?
Why does missing the implicit activities lead to a misleading schedule?
Not all activities are visible in the Bill of Quantities (BOQ). Implicit activities like curing, compaction test approvals, or authoritiesā€™ handover procedures are rarely listed, yet they consume time and resources.
Ignoring them can create misleading schedules.
For example:
Compaction may take 5 days, but waiting for test certificates adds more.
Authoritiesā€™ approvals at project close can span months, even if the detailed breakdown is not stated in the contract.
When these implicit tasks are overlooked, schedules appear longer or delays seem artificial.
The result is inaccurate progress tracking and weaker claims for extensions of time.
A robust schedule must account for both explicit and implicit activities.
Only then can a project plan reflect reality and ensure fair, transparent delivery.
