A new tunnel formwork system from Pilosio reduces the time needed for assembly. Made from standard components, this can be used for a wide range of geometries.
Advanced bridge formwork solutions are allowing contractors to complete vital major highway infrastructure projects covering Norway, Sweden, Estonia and Poland. Guy Woodford reports
Building the Labbdalen bridges in Norway is a key feature of the E6 highway improvement programme. Main project contractor HÆHRE tasked RMD Kwikform and Teknikk with supplying a complete formwork and shoring solution that could tackle the challenging Norwegian terrain, whilst preserving the environment.

Develon has launched the DX235RTF-7 tunnelling excavator, an extension to the company’s line-up of special application machines.
The DX235RTF-7 is based on Develon’s well-established DX235LCR-7 reduced radius crawler excavator and is powered by a DL06V Stage V engine, providing 141kW of power. The DX235RTF-7 uses the successful compact design and minimum swing radius of the DX235LCR-7. However, the key part of the machine is the heavy duty tunnelling front, offering a new arm and boom design with special kinematics and a tilting function.
Versatility and productivity are key drivers for the concrete plant sector - Mike Woof writes. The days of most construction machines being expressly designed and built for a single specific purpose have gone. These days construction equipment is largely intended to be versatile and adaptable, allowing it to be operated in a wide array of applications and duties. New concrete plants are designed too for mobility as this allows users to set up highly productive equipment quickly on basic sites, with little p
Seattle's State Route 99 viaduct is coming down. David Arminas was on site.
Bertha, the world’s largest diameter earth pressure balance tunnel boring machine, with a cutterhead diameter of 17.5m, is no more. Her 2.7km journey underneath the waterfront area of Seattle finished on April 4 and the power went off for the last time on an extraordinary TBM that had finally completed an extraordinary job.
“A small sidewalk job would have had more impact on city traffic than we have had,” says Brian Russell a v
