Ledcor-Haisla Limited Partnership (LHLP) was awarded the Heavy Haul Roads scope of work for the future Liquid Natural Gas (LNG) export terminal. The work included constructing a 2.5 km x 33 m wide heavy haul road for self-propelled module transporters to move heavy modules from offshore transport vessels for construction on the plant site.

The scope of the Heavy Haul Road project consisted of an embankment of 300,000 m3 of structural fill placed on 200,000 m2 of Stratagrid and the construction of retaining wall structures comprised of one 150 m x 3 m high lock block wall and four 150 m x 4 m MSE Gabion basket walls. Also responsible for maintaining fish habitats, LHLP installed two large pre-cast culverts, one 1,600 mm diameter 50 m, and one 3,000 mm diameter 70 m, both filled with rock substrate for fish spawning. LHLP also installed 8.2 km of 4” to 30” HDPE utility pipeline and piping along the 2.5 km road and tank pad area inside the plant as part of the plant's underground. These underground utilities also included the Moore Creek utilities crossing section (MCX). MCX utility construction was completed using an innovative 1.5 m double-barrel flume for a live-creek diversion. In addition, sheet piles were utilized as shoring as the excavation was located adjacent to the existing SHHR and its seven layers of specialized geogrid. As well as the Tank Pad and MCX utilities were completed without any incident.
