Kaikōura Earthquake Recovery

Since November 2016, Isaac Construction has been working for NCTIR, providing skilled people and resource, to supply and deliver a variety of works. Our teams worked alongside teams from numerous other companies and disciplines, all working towards achieving the same goal, to recover the infrastructure and re-open Kaikoura.   

Isaac Construction’s first involvement with NCTIR was the colossal task of clearing the hundreds of thousands of cubic meters of slip material, which completely blocked both the road and rail, extending into the sea. We deployed four of our 30T dump trucks and skilled drivers from our McLeans Island quarry. The government promised to have the road open in one year from the earthquake; it meant the earthworks team were required to work 24/7 to clear the slips one by one, to allow the civil crews to begin rebuilding the demolished transport network. Once enough room had been created, NCTIR requested as many trucks and drivers as possible to join the 24/7 operations. This resulted in 11 trucks and drivers, a significant proportion of Isaac Transport fleet, heading north to join the team.

Following the slip clearance, the resource and skill requirements changed from earthworks, to civil and drainage. We acted quickly and deployed a highly experience drainage teams to join the Site 1 team, to construct the new stormwater system. We were given strict targets due to the major milestone goal of opening SH1 to the public, for the 2017 Christmas period. This was a time when the construction works was happening quicker than the design team could issue out. Constant design changes with a fixed finish date, made it a technically challenging project. The stormwater design included precast manholes, 375mm PVC pipelines, subsoil drains, and rail culvert crossings. Every item was constructed and inspected to NZTA specifications. Therefore, quality could not be compromised. To achieve the goal the teams worked 24/7, by rotating days, nights and weekends between the Fulton Hogan and Isaac drainage crews.

Isaac Construction completed emergency works to the total value of $9.4m and were award Subcontractor or the Year at the 2018 CCNZ Canterbury awards for our contributions.
