10. Are the maps accurate enough to follow as a guide to line location?

Yes

11. Is there an assumed number of leaks we will find (Grade 1, Grade 2, Grade 3)? This will help budget time to perform survey. If there are not, it will be difficult to identify how much time will be spent at each leak once found and pinpointing/barholing leak.

No there is not an assumed amount of leaks. This is why the survey is being done.

12. Following Grade 1 Leak protocol, Gas leaks of this magnitude need to be shutdown or mitigated once found. Will this responsibility fall on the contractor (i.e. will there be standby time for each Grade 1 leak as found to mitigate the leak or will this be the bases responsibility after the leak is found).

This will be the bases responsibility once the leak is found.

13. Are there any special certifications, licenses required to perform leak survey work?

No as long as the proper equipment is being used, flamepack, barhole survey.

14. Can the survey take place using multiple teams to survey? (Will leak response team be overwhelmed if leaks being reported from multiple survey teams).

Two teams would be ok; more than that we will not have enough manpower to fix leaks and provide escorts.
