Thanks for update. In order to reduce risk in communication, I advise to ask TRC site team to strictly follow the Work Packs. If any deviation is required, they need to re-submit the WP and receive approval for that.
As CM and Engineering team are working on multiple project, they don’t have sufficient time and are susceptible to misunderstanding and miscommunication. So, I requested their support to always review Work Pack in detail and cross-check it with calculations. For Site Team, Work Pack should be like your ultimate reference to avoid any misunderstandings. Therefore, make sure that TRC capture all changes in the Work Packs.
