I am writing this letter on behalf of the survey team. As you mentioned in your letter, that in a few days ago, survey teams have not yet arrived at the site at the time this happens because of the way our team explores many of the monitoring work and to communicate with the survey of the RT team. to access the quality of jobs, but the team has not been notified to the survey team advance notification that a tunnel would have to move slowly into the audit schedule. The way our team explores so I apologize to the team tunnel. On the quality control work next to the survey team will go to work or to attend a scheduled inspection, if there is a change to the schedule can make an exploration team tasks, through the team tunnel is known.
We are one of the teams working for the same goal, and the team is always available to support your survey anytime you want.
