This is Ralph. He is drilling a 400mm hole in the side of a pipe.
This process involved bolting on a hydrostress drill rig to the concrete required drilling a 400mm hole. Due to the location of the hole required, the drill rig was mounted on an angle as can be seen in the above images.
Ralph works for Sharp Concrete Cutters and Drillers. He is a professional concrete driller and has specialised training in order to determine how the hole ought to be drilled, and what equipment was required to do the job.

Designs unveiled for new landmark attraction in the city centre.
Interactive lights, Maori carvings and a vibrant magenta surface are set to turn the old Nelson Street motorway off-ramp into a must-see Auckland attraction for people to walk and cycle across when it opens later this year.
The off-ramp is being transformed into a shared path as part of the Nelson Street Cycleway, one of a network of cycleways being delivered in partnership by the NZ Transport Agency (NZTA), Auckland Council and Auckland Transport.
It will connect to Upper Queen Street by a new bridge off Canada Street – the last piece of which was lifted into place in mid-October – and will continue to Nelson Street where a separated cycleway is being built.
The design was developed following an online survey in June when Aucklanders called for it to be ‘modern’ and ‘distinctly New Zealand’. It includes LED lights lining the safety barriers that can interact and pulse as people pass them, as well as a strong magenta surface colour that will fade out at the northern end in a Maori design.
Political urban design champion councilor Chris Darby says: “This project shines a light on walking and cycling and offers an inspiring new way through a previously impenetrable spaghetti junction. It offers a seamless walk-across-the-rooftops connection into the city centre, with sweeping views of the city and harbour. The innovative design catches the eye and captures the imagination, heralding the future of transport across Auckland.”
A more attractive transport choice
The concept has been created by Monk Mackenzie architects and LandLAB, in association with artist Katz Maihi. Maori patterns and narrative form a core part of the designs, following discussions with iwi.
The path includes etched carvings at intervals along the length, with a 6 m pou at the entrance. The colour represents the heartwood of a freshly cut totara, with the red and pink shades strengthened to contrast with the surrounding motorway lanes.
Brett Gliddon, the NZTA’s Auckland and Northland highway manager, says: “It’s great to see the beginning of our urban cycling future here in Auckland with a wonderful facility like this. It’s helping to make cycling a safer and more attractive transport choice as well as leading the way in world-class cycling infrastructure.”
The off-ramp was closed a decade ago, and transforming it – as highlighted in the council’s city centre masterplan – has received strong support. Barbara Cuthbert, Cycle Action Auckland chair, says: “This cycleway will be the highlight of all the new projects we’ve seen in the city so far. It’ll be a beacon attracting people to walk, cycle and delight in the views – a new landmark for Auckland.”

The 880F4 cutting system offers the superior strength of FORCE4™technology in a package that meets industry standards of design and ergonomics. Builtfor the hardcore cutter, this sleek powerhouse is packed with features designed to make it the hardest working saw ICS® has ever made.
Six of our Concrete Cutting and Drilling Technicians worked together today on one job site. This is a rare occurrence as most of the jobs are spread across the city in any given day.
The sound of six petrol powered hand saws running simultaneously was a thing of symphonic beauty. This could only be achieved because our crew is big enough to handle the big jobs and yet small enough to do the best job every time.
