This prestigious subdivision for the Kaipara Group is situated between Whitford and Clevedon. Developing the challenging 160 hectare site required extensive undercutting in steep gullies and significant cut to fell operations.

This five stage award winning development was completed in 2017. Our earthmoving and civil crews did a great job with the sections, two wetlands, walking and cycle tracks and deserved the acknowledgments they received.



We recently completed the tailings dam for Oceana at the Waihi gold mine.

Taking six months to complete in bad weather, just over 100,000 cum of constructed fill was used, including mixing lime with the material to counter acidity. It’s a complex process but we complied with all consents to finish the job to the client’s and our satisfaction.



We relieved a slip at the J. Swap quarry (south of Cambridge) and removed 1.2m cum over burden in about eight months work.


Waikato Expressway

We completed contracts on two sections of the new expressway for Hick Bros and Ross Reid Contractors on time and budget. On the Ngaruawahia section we committed 28 personnel operating three 100 tonne and seven 50 tonne dump trucks, five excavators including a 110 tonne capacity Komatsu PC-1100-6, five Caterpillar dozers and two graders.

In 2014 we successfully built a large water retention superpond – 300m x 100m that has a capacity of 100,000bcm. The job was completed using Komatsu 65 tonne and 45 tonne excavators, three 50 tonne payhaulers and three Komatsu HM400 ADT units.



This large project completed for Perry Resources at Waingaro Quarry, required work focused on the environmental aspects of the large visual bund project, which included building 0.5ha wetlands and 400m of new stream habitat to create fish passage through a 250m culvert. This involved building in excess of 30 small rock check dams to allow the water to drop in elevation approx 7m, while still ensuring fish move upstream.

We completed removal of the large coffer dam that was constructed at the time and finished work on the intake structure and landscaping.




C & R completed the earthworks contract on the Clearwater hydro project at Te Anga in the Waitomo District last year. This difficult job required excavation of a 750 metre long cutting to allow for the placement of a two metre diameter steel pipe (laid in 12 meter lengths). Excavation was testing, as the materials encountered varied from sensitive clays to massive limestone boulders requiring drilling and blasting. This work was sub-contracted to the very professional and competent RedBull Powder Company.



Having won the contract by negotiation, from 1993 to 1997 BCL undertook earthworks on the Yamo section of the expressway to the new Hong Kong airport, as a sub-contractor to AOKI Corporation of Japan.

The project involved the construction of 5.2 km of highway, four million m3 of rock excavation (3.2m blasted granite all used as fill), sea wall construction and rip rap. The contract value was $55.7 million.

BCL had 15 New Zealand staff from a total of 60 on site. The Kiwis included the management team, earthworks supervisor, engineers and mechanics.

Additional locally sourced labour saw a total of 200 workers on-site overall. Major equipment included large Komatsu excavators and 50 tonne Komatsu trucks.




BCL was involved in this major project over a ten year period. Contracts and plant works included initial river diversion cut, fault line excavation, and buttress excavation. BCL undertook major sections in the Cromwell Gorge, which included Brewery Creek to Jackson's orchard, Champagne Gully to Sonora Creek sections and the Bamockburn contract. BCL was also heavily involved in the slip buttress works in the Clutha river.




BCL was the largest contractor on this massive project. Contract and plant day works were carried out over a ten-year period, including contract 515 and 516 for the Pukaki - Ohau canal section.


In 1981, BCL was awarded two contracts to construct both the upper and lower canals near the powerhouse on the Maniatoto irrigation scheme. The work consisted of excavating schist rock to form canals, lining and wave protection works.
