Question 1

If BIS and employer specification conflict, which wins?

Accepted Answer

The contract documents should establish precedence; escalate to the engineer if silent.

Question 2

Can we accept a mill’s internal specification instead of BIS?

Accepted Answer

Only if the contract explicitly allows equivalency and the consultant signs off.

Question 3

Are older IS revisions still valid on site?

Accepted Answer

Depends on contract reference date; do not assume automatic rollover to latest revision.
