Answer 2

Phillip has been (1) my best friend for over 30 years. We have known (2) each other since we were children. We studied (3) at the same school and graduated (4) from the same University of Underground Engineering in our past. Recently, he and his family moved (5) to a house on the same street as me. They live (6) in an old house near an abandoned mine, and now I'm very glad that they have become (7) my neighbors. For the last 10 years, Phillip and I have worked (8) for the same engineering company. We have just gotten back (9) from work. We have been (10) working on our current project for 2 years already. So, 2 years ago our company started (11) the tunnel under the river. It became (12) the most important thing in our careers as well. Last week we finished (13) developing the central block and fully passed (14) the upper adit. During this week we have been preparing (15) everything for opening the calotte. So, we have just started (16) to move temporary tunnel support to the upper adit level. We need to be sure that the vault is protected well against falling down. The explosion crew has been drilling (17) the blast-holes on the low level to extend it to the side-blocks by blasting after the calotte is finished. We have already met (18) a lot of difficulties while dealing with incoherent ground here, limestone mostly on the upper part and quite solid rock on the lower one. So, we have had (19) the main problem to solve by combining soft and hard rock tunneling techniques. There have been (20) ground water leaks and rock slides as well, but we have successfully coped (21) with these problems using appropriate technologies, adopting our equipment, knowledge, and cutting techniques to such changeable ground conditions. We have also made (22) the track gauge wider to make it more stable and tolerate heavier loads. We have created (23) the tunnel project to be inclined not only on the ends of it leading to the daylight. We have supposed (24) our tunnel to be inclined along the whole length of it because our chief engineer has always believed (25) that such a feature can make it safer, more stable, and perform its features for a longer period.
