Change order conditions

Change orders cannot be issued if the aggregate cost increase exceeds 25% of the original cost, or if there's a decrease in work due to deleting work items.

Variation Order Exclusion

A supplemental agreement is not considered a variation order; while change orders and extra work orders are.

Time extension eligibility

A project delay due to uncontrollable factors might allow a time extension if critical activities, as shown in PERT/CPM, are affected.

Retention rate for progress payment

If work is satisfactory and on schedule after 50% completion, no further retention is required. Otherwise, a 10% retention rate is applied to progress payments.
