PROJECT EXAMPLES

CHRISTCHURCH INTERNATIONAL AIRPORT

Abseil Access was contracted to remove the chainmail and install vertical pickets on the Iconic “vortex” façade, wrapped around the Christchurch Airport Air Traffic Control Tower.

Using a five-person rope access team, Abseil Access provided constant removal and installation of the picket elements. Back up and rescue systems were pre-rigged into our access solution.

HISTORIC BRIDGE REFURBISHMENT

The Springvale Suspension Bridge was built in 1923 and was New Zealand’s first engineering heritage structure.

Abseil Access was engaged to perform a major refurbishment of the timber bridge with services including; replacing 10% of the timber decking, applying corrosion protection to steelwork, improving of access points and maintenance of the main cable, anchor block and anchor bar.

STACK INSPECTION & MAINTENANCE

Our team was tasked with performing inspection and maintenance work on the 146m aluminium smelter chimney.

The concrete structure requires regular inspection and various maintenance tasks(concrete structure inspections, coverage surveys and repairs), which are not practicable by any other means but rope access.

This method also allowed for movement onto different portions of the stack as the weather or task changes, with no equipment left exposed.

BRIDGE 19 INSPECTION & MAINTENANCE

Abseil access were engaged to complete detailed rope access “find and fix” on bridge 19 which is located on the Midland line of the South Island in Springfield. This 6-month campaign included Close Visual Inspection (CVI), treatment, and re-installation of all accessible hold down bolts. The principal maintenance repairs included replacing bolts, damaged structural members, coating touch ups removal of 400m of rail system material from the lower chord, replacement of all loose rivets, corrosion treatment between plates and cleaning and greasing of bridge bearings.

TIWAI POINT, CONCRETE STACK

Producing aluminium at 98.98% grade of purity, the 146m main chimney stack at Tiwai Point Invercargill is the centrepiece of the NZ aluminium smelter. The concrete chimney requires regular inspection, and maintenance tasks which can only be performed by rope access. Abseil Access have provided inspection and repairs for NZAS since 2002. This project included rope/specialist access, concrete structure inspection, concrete coverage survey, safe removal of spalling material, concrete repairs and conduit install. Our equipment and methodology minimised weather impacts enabling completion in 10 days.

CAPE FOULWIND CEMENT PLANT

Abseil Access Ltd were contracted to inspect the 4 cement storage silos, 3 chimneys and 5 water storage silos using rope access and specialist access systems. The chimneys are 50m and the silos up to 40m high. Spall sites were marked, measured, and recorded. Serious concrete deterioration at the top of two of the chimneys resulted in removal of 15m of concrete and brick lining. This required installing a temporary upper platform, scaffold and crane lifting operations. The inspection of cement and water storage silos was followed with a full repair programme for all spall sites.

NATIONWIDE SILO REBRAND

As part of a national rebrand, Abseil Access Ltd were contracted to remove all the existing Milburn logos, apply a white coating system, and apply the new 3 colour Holcim super graphic.

This nationwide project involved 17 logos on 9 sites with steel and concrete silos up to 40m high. Resene paints were selected along with UV stabilised epoxy acrylics compatible with the variety of existing coating encountered. Three teams of rope access painters and technicians were required to complete the project within the time frame.

LIGHTHOUSE PAINT & BLAST

Abseil Access Ltd were contracted to remediate a 110-year-old, 16 Meter high, cast iron lighthouse located in Kahurangi National Park. The site was challenging with no onsite water, power, accommodation, communication, or road access. This meant establishing the site required transportation of 16 tons of equipment by helicopter. The project required removal and containment of the original lead-based paint. The bare cast iron was then garnet blasted to SA2 before six coats of Resene epoxy paint were applied. The eight-person team completed the project within the designated seven weeks.
