Hello. A previous CE-10 is already closed with no time impact (revised drawing of CE-10 compared to CE-01).
Now, the Contractor is submitting a new CE (say CE-50) due to another set of drawings (revised drawings between CE-50 vs CE-10) and now want to include the impact of a forgotten impact of CE-10 (part of changes brough by CE-10 drawings). This forgotten issue is already shown in CE-10 drawings but forgot to assess by both PM and Contractor in CE-10.
Can the Contractor include this forgotten issue in CE-10 to the new CE-50 since CE-10 is already closed without considering the newly found forgotten impact? Any related clauses? Thanks.
