Quantity/quality: Undertake personnel interviews

Interview relevant personnel of the RA, project engineer, BuildWell or relevant sub-contractor or supplier who may have knowledge of the relevant issues.  E.g.:

• project manager
• procurement manager
• site engineer
• site supervisor
• site quantity surveyor
• supplier manager who dealt with the relevant materials orders
• truck drivers who delivered the relevant materials to site
• labourers and plant operators who laid the relevant materials.

Do their recollections of the issues in question match the documented records?

Did anyone compel them or encourage them to change any documented records, or write incorrect information?
