PO was issued on July 4th to Plan B, that was two months ago. If there is any further delay at NG roof then Plan B should do the roof above Retail corridor as per schedule and not wait to finish NG first.
The longer Plan-B takes to do water proofing at the PRV station above Retail Corridor then the higher the risk of the Retail corridor ceiling collapsing again due to possible heavy rain and flooding, it has happened twice this year and we cannot afford a third incident hence request that the Retail area is given priority and dates are not changed again.
