Advanced machine control technologies are speeding site layout and construction operations Canadian house building firm Mattamy Homes has brought in a contractor that has used sophisticated equipment to build the roads around its new development in Oakville, Ontario. The site is just 30 minutes drive from Toronto. Phase 1-A of the project is under construction and nearly every one of the 550 homes that will be built there has been sold already. Additional phases will bring the total number of homes to 1,800

Two important routes in Germany, the A9 and A6 autobahn highways, have benefited from the use of the latest Wirtgen slipforming machines. The A9 is a particularly important route in Germany as this 529km link connects capital Berlin with the southern city of Munich, running through Brandenburg, Saxony-Anhalt, Saxony, Thuringia and Bavaria.

In Tucson, Arizona, contractor McNeil brothers is using a two-track GOMACO concrete slipformer on a 3.2km stretch of highway. This project is for the Arizona Department of Transportation (ADOT) and involves widening Interstate 10 to four lanes of traffic in each direction between Ruthrauff Road and Prince Road in Tucson. This new stretch was needed to better handle increasing traffic demands in the city and includes rebuilt entrance and exit ramps to improve access to the city.

The firm has been using the machine on the US$64 million project to resurface a section of Interstate 20, close to the city of Columbia.

Canada’s vast tar sands operation is providing a major financial boost to the country and this industry has relied heavily on Fort McMurray airport. Situated in Alberta, Fort McMurray is a remote town that has seen a huge expansion following the upturn in activity in the tar sands operations nearby. Although the massive resource has been worked for decades, only in the last 15 years or so have new extraction methods made the operation truly economic. Since 2010 Fort McMurray’s population has increas

With an increasing number of aircraft using Jeddah International Airport in Saudi Arabia, the authorities realised there was a need to upgrade the facilities. King Abdulaziz International Airport opened in 1982 and serves over 15 million passengers/year, with a high percentage travelling on the annual Islamic pilgrimage to Mecca, some 80km away. The city has the largest port on the Red Sea and is named after Abd al-Aziz ibn Saud, the former king and founding father of Saudi Arabia, and is one of the kin

Upgrades to a slipform concrete paver built in 1999 allow it to use current technology. US firm Streb Construction has taken a novel approach to its paving fleet by upgrading a CMI paver built in 1999 to use modern machine control technology. The company bought the CMI SF3302 machine new and this piece of equipment had logged a high number of hours since its purchase. However the company realised that this proven piece of equipment could be made to operate more efficiently and productively, as well as more

Machine control technologies were pioneered in the concrete paving sector with systems having been used for over 10 years. Leica Geosystems was the first of the machine control technology suppliers to offer these systems on concrete slipforming machines and has developed a strong position in this segment. However the company met resistance from some quarters in the construction market and specialist Karl Soar said that some contractors were very reluctant to give up using conventional stringlines. He said,
