Civils in top gear

 

Progress on the country’s transport network has accelerated again as civil engineers reach milestones on major road and rail schemes.

On the rails, new transport minister Humza Yousaf has been on site to see progress on the £60m Queen Street project, the largest engineering work on the Edinburgh-Glasgow railway since it was built in the 1840s.

Since the high level station closed to trains on March 20, more than 2,100 workers have been renewing track through the tunnel, lengthening and rebuilding platforms and track layouts.

The 20-week scheme remains on schedule and the project team has completed the first line of new slab-track and operations have started on laying the second line. More than 5,000 tonnes of concrete and rock have been moved to clear the way for a new 945-metre concrete base and 820 metres of new slab-track units and 2,000 metres of new rail have been laid.

The tunnel renewal is part of the programme to electrify the main Edinburgh-Glasgow line. Click here for video

On the roads, a ground investigation contract worth nearly £1m has been awarded to Soil Engineering Geoservices Ltd for work on the 8.5 km Tomatin to Moy section of the A9. It’s expected to begin next month and take around seven weeks. It will be the first of a series of ground investigations to be carried out across the dualling programme this summer as design continues to identify preferred routes.

Elsewhere, Transport Scotland has released time-lapse footage of recent heavy lifts at the largest single-span bridge being built on the M8 M73 M74 Motorway Improvements Project.

The Liebherr LR1350 is owned by Inverness lifting specialist Weldex and was used on construction of the North Calder Water bridge to lift nine pairs of three-metre high steel beams, around 77 metres long and weighing almost 2,000 tonnes.

At 77.25 metres the structure is one of the widest of the project and placing the beams was described as “a significant milestone”. Click here for video
