Alva Construction Ltd. streamlines pile driving with new visualization and control system
By Judith Powers
As Alva Construction Ltd. Of Antigonish, N.S. began the timber pile component of a major project to replace the fishing wharf at Little Dover, N.S., engineering manager Reg Tramble was looking for a machine control system that would streamline the placement of the piles.
The job involved driving 180 timber piles – 132 bearing or vertical piles and 48 batter piles in the L-shaped pile work wharf section. Positioning and adjusting the angles of the batter piles had always been accomplished by crewmembers in a raft, which in addition to being time consuming, presented an element of danger to the crew.
