What do I do if I enter under guarded access and then discover the scope of the job is larger than I thought?
If you are in the tunnel under a guarded access and the job looks like it will take longer than 30 minutes, phone MCC x2151.
Tell them that you wish to go to permitted access and give your new time estimate.
