Transmission Gully - Cut 40
Project Overview: Bulk earthworks, drainage, and environmental controls for construction of Cut 40 and Fill 41-42 of the Transmission Gully Motorway. Job started January 2017 and the weather was extremely wet until September with Wellington’s yearly rainfall achieved by this time! A huge amount of earthworks achieved up to this point.
Interesting Points
Total earthworks volume including topsoil handling, cut to fill in Wellington Greywacke rock, unsuitable, and other miscellaneous earthworks was over 700,000m3.
Achieved daily volumes consistently of over 10,000m3 solid fill volume. Best day 13,300m3! Huge achievement
50m deep fill batters all trimmed with GPS machinery, topsoiled and prepared for planting. Mulch cover put on by Goodmans team.
Very steep site with limited access. To remove unsuitable in the gully’s, we towed the 30 tonne dumpers out with a D6 dozer. They also had to be lowered back down. Motorscrapers were descending at 58%.
50,000m3 of R2 rock ripped by Cat D9 and D10 Bulldozers
