Piling Projects

Project Name - Puhinui Footbridge and Sheet Pile Across Rail Corridor

Client	Hawkins Infrastructure
Principle	Kiwi Rail and Watercare.
Consultant	PETERS AND CHEUNG LIMITED
Project Duration	6 Weeks
Project Scope	Footbridge piles for railway station and water pipe crossing the rail corridor
Machines Used	7045 Crane, 7055 with PD6000, Ape Vibro Hydraulic Hammer, Ex120 and EX40.
Challenges	The 60 metres of sheet piling which crossed the main trunk line had to be completed in less than 30 hours to allow for the 2m diameter pipe to be installed over the Christmas shutdown. Our part started 6.00am Boxing day and needed two crews working two shifts around the clock, Three 50 Ton cranes were on site as well as three hydraulic vibratory hammers to allow for any breakdowns that could occur. Our portion of the project was completed ahead of schedule which considering the dire weather that was encountered was a huge achievement. The crews then concentrated on the driven piles for the foot bridge, 40 piles down to 30 metres. These piles also tested our guys as the rain was relentless. The piles were installed ahead of schedule and were finished on New Year’s eve giving everyone a chance to celebrate.

Project Name – Ratcliffe House Piles - Hamilton

Client	Construct Limited
Principle	Robin Ratcliffe
Consultant	Design Engine
Project Duration	10 Days
Project Scope	To Drill 12 house piles up to 1500 Ø, 21m deep
Machines Used	Soilmec R312, Kobelco 7055 Crane, EX120
Challenges	Site access for this project was particularly challenging due to a long, narrow driveway. The driveway measured 300m in length and 3.2m in width, making it a very tight fit for our machinery. Each piece of machinery was measured to the nearest mm, and trees were trimmed where necessary to allow access. Delivery trucks were required to reverse the entire length of the driveway, as there was no room to turn around on departure. Specialised house-moving trucks were used to deliver the reinforcing cages. No onsite storage was available, so materials were bought to site in stages. The project was completed successfully and on time with a TVNZ film crew recording our progress for an upcoming television programme.

Project Name – Arrow Tower – St Heilers, Auckland

Client	Arrow International
Principle	Telecom
Consultant	Tokin and Taylor
Project Duration	4 Days
Project Scope	A single pile of 1500 Ø, 4m deep- inside a telecommunications tower
Machines Used	Hired crane, modified Vibrator Head
Challenges	The site had one point of access; a driveway between two buildings just 2.3m apart reducing the options for machinery. Using a very small hired crane, part of the roof was removed. The hole was dug by hand (into sandstone) and a permanent caisson was vibrated into position. With machinery access impossible, a vibrator head was removed and dismantled from one of machines, then successfully modified to suit the situation. As concrete trucks could not access the site, they were parked on the road, and the concrete was pumped down the 50m driveway.

Project Name - Western Network Line Upgrade - Raglan

Client	Balfour Beatty United Group Ltd
Principle	W.E.L. Networks
Consultant	BECA
Project Duration	May - August 2010
Project Scope	To carry power generated by the new Te Uku Wind Farm by Meridian Energy, an upgrade of the existing 33 kV transmission line from Te Uku to Te Kowhai substations was required. 149 pole foundation piles were constructed, ranging in depth from 3.0 m to 9.5 m, and a diameter of 1.050 m.
Machine Required	Komatsu PC 200 and Volvo EC140B pendulum rigs, Bulldozer and 4WD tractor with trailer and helicopter for material deliveries to remote sites.
Challenge	In the soft ground conditions full length permanent caissons were required. The caissons needed to be airlifted into place in sections due to the helicopter’s lifting capacity. Some of the piles were located in areas with basalt rock present, resulting in our crew having to be prepared for all eventualities. Our piling crew carried out the project through the heart of winter. Specialized and/or difficult projects are where Spiral Drillers Civil Ltd excel.
