Tackling one of SCIRT’s biggest challenges

The Stronger Christchurch Infrastructure Rebuild Team (SCIRT) set out in 2011 to repair Christchurch horizontal infrastructure within five years. It took on Fulton Hogan to tackle one of the toughest projects. The SCIRT Sumner Road Stage 4 project involved the re-strengthening of an existing retaining wall that supports Sumner Road above the Holcim Cement site. The retaining wall earthquake repair and strengthening consisted of three existing 100-year-old stone walls up to six metres high. The design called for 180 new soil nails to be drilled through the existing rock and grouted into place up to eight metres long and 180mm CATEGORY in diameter. 2 FINALIST Once the soil nails were completed, drainage was installed, a footing was dug and poured and a reinforced shotcrete facing was applied in two layers of 150mm. A new handrail and repairs to damaged kerb and channel and footpath completed the project. SCIRT’s Fulton Hogan delivery team was involved from the design phase through to the delivery of the project, which started January 12, 2015 and was completed September 11, 2015. The project cost was $1.45 million and was completed ahead of schedule and under budget.

Fulton Hogan says its team typically took a hands-on approach, getting buy-in from all staff on what was one of SCIRT’s biggest projects.

“The retaining wall repairs on Sumner Road, which links the port suburb of Lyttelton with the seaside suburb of Sumner and provides an alternative route to the port from Christchurch, was a challenging project for all involved.”

The project included “tough ground conditions”, as Lyttelton is built on sloping terrain, with its international seaport and associated trade located on reclaimed land.

“The project was a success by finishing ahead of schedule, under budget, and stakeholders were satisfied with the finished project and how everything ran during construction.”

SCIRT management confirms this: “The [Fulton Hogan] team excelled, despite these challenges and delivered a quality project to the client ahead of schedule. SCIRT was also impressed with the positive feedback received from the locals and that the community was satisfied with the construction.” l
