Case Study: Alva Construction achieves 50% faster wharf pile placement and improved safety with Trimble Marine Construction 3D software

3D Software Halves Wharf Pile Placement Time

Trimble Marine Construction software was used on an Alva Construction wharf replacement project in Nova Scotia that required driving 180 piles (132 vertical and 48 batter) from a barge-mounted crane. Alva needed faster, safer positioning and pile-driving guidance because manual crew positioning was time-consuming, hazardous, and they wanted GPS machine control for their floating crane.

Systems integrator Measutronics fitted the crane with pitch/roll sensors, dual GPS antennas, Trimble GNSS receivers and a cab-based laptop running the Trimble software, providing real-time on-screen guidance for location, heading and inclination. After installation (with the project 65% complete for before/after comparison), vertical pile set-and-drive time dropped 40–50% and batter piles by 25% (with an expectation of reaching 50%), improving safety and reducing production time.
