Winter excavation continues

March 7, 2016

By the beginning of March, our caisson wall has been completed and approximately one third of the tiebacks are installed. To accomplish this a trench has been excavated close to the wall allowing the tieback drilling rig to maneuver.  In addition, in preparation for the tiebacks, the round caissons have been ground flat.  The tiebacks will be stress tested before the next operation.

Our next step is to backfill the Phase 2 excavation and dig down to the bedrock for Phase 1 where the first footing will be poured.

We continue to be on schedule with our construction activities.

Look for further updates, when we are ready to pour the footings.
