I had a question about the work taking place at Pier 9. McNally construction currently is building a new Quay to serve as a Home base for the new AOPS vessels under construction at Halifax Shipyards. The dredging work was completed over the winter, and they are now pouring the blocks that make of the Quay.
The blocks are individually slipformed on a semi-submersible barge, then floated off when complete, towed to their final location and sunk into position. the blocks are hollow, and will be filled with rock, and the whole area will then be backfilled, and paved over.
A completed block, tied up at Pier 9
A new block, just underway.
The whole process hasen’t changed much in close to 100 years – this is the same method used to construct the Ocean Terminals almost 100 years ago
One Final Note: Why is it a Quay?
