Rio 2016 Olympic Canoe SlalomBrazil

Rio 2016 Olympic Canoe Slalom

Ground has broken in Deodora, Brazil and construction work is well underway. The team that delivered the London 2012 Canoe Slalom course is delighted to see construction of their next Olympic facility well underway in Rio de Janeiro for the 2016 Games.

Whitewater Parks International (WPI), supported by the engineering team at Cundall have prepared the detailed concept drawings for the whitewater channels, lake, pumping stations and boat conveyors.

The integrated 2016 Canoe Slalom venue design has been completed by the architectural and engineering consortium responsible for the whole of the Deodoro cluster of venues and it is now being built rapidly in a race against the rainy season.

Following the successful 1:13 scale hydraulic modelling exercise commissioned by WPI, in collaboration with the Czech Technical University, all stakeholders have approved the design.
This has allowed the design phase to move quickly into construction.

The team has an ongoing role in advising on the procurement of the fit out which are fundamental to the success of the venue. These include the water pumps to deliver a combined flow of 22.5 m³/s, the boat conveyors, the channel obstacle system and the slalom gates.

The venue is due for completion in 2015.


Road construction company invents new machineAustralia

Road construction company invents new machine

A road construction expert on the NSW mid north coast of Australia has taken heed of the old saying about “building a better mousetrap”, by creating a unique machine to improve the efficiency and cost effectiveness of his business.

Leigh Brenton, owner of Bulahdelah-based Guardrail Systems, installs guardrail, wire rope and safety barriers under contract to local councils and major road authorities.

Leigh has combined a JCB 527-58C telehandler and an Orteco post driver hammer to create a machine that can carry, distribute and install rail posts.

JCB Construction Equipment Australia worked with Leigh and his team of specialists to customise the machine and install a remote control operating system.

When I started in this business in 2004, I had a standard tractor and a drop hammer, like a farmer uses to put up a farm fence. Two years later, I realised it just wasn’t the right way to do it.

Leigh’s first attempt involved another tractor and a pneumatic hammer. After some research, he locked onto the idea of combining a hammer with a telehandler.

It was effectively a one-man, one-vehicle operation and I thought this was the most efficient way of doing it so I decided to go down that route. There is a hammer available that is mounted on a track machine, and it’s great, but all it does is drive a post in, nothing else. So I decided to buy a hammer and a JCB telehandler that is strong enough to manage loading and carrying a pile of posts or a 1.5 t roll of wire, and add one to the other.

Leigh’s telehandler can be operated like any other. In manual mode, it loads and unloads trucks and carries the posts. A remote control that drives the telehandler also allows for the operation of the hammer, locking off the fork function.

Leigh now believes he has the perfect machine for the job he does, and he is very optimistic it will give him a distinct advantage in a highly competitive industry.
