Scottish Transport Minister Oversees Start of Works on A9 Ground Investigation

Soil Engineering were recently awarded the Birnam to Tay Crossing Ground Investigation work package, a five mile section of Transport Scotland’s £3 billion A9 Dualling scheme.

It is proposed to improve and upgrade the existing A9 between the Pass of Birnam and the River Tay Crossing, from single carriageway to dual carriageway standard. The ground investigation is being undertaken to provide geotechnical and geo-environmental information for the design process for the new road scheme.

The objective of the investigation is to form exploratory holes in soil and rock to obtain samples for geotechnical analysis whilst facilitating in-situ testing and the installation and monitoring of in ground instrumentation.

The investigation works are to be undertaken on or adjacent to the existing A9 carriageway and the existing Highland Mainline Railway, as well as a number of water courses and environmentally sensitive areas.

Scottish Transport Minister Keith Brown was on site 27th May to meet Soil Engineering and to officially launch the start of the works. Mr Brown said “Our commitment to dual the A9 between Perth and Inverness is unwavering, and underlined in recent weeks with the first of three multi-million pound design contracts awarded, and the remaining two expected before the year is out”

“I’ve seen for myself today the start of ground investigations work for the section between Birnam and Tay Crossing which is vital to help inform the design process and help move towards publishing the draft orders next year. This section presents some particular challenges and we are working hard to minimise any impacts to properties, the railway and the environment.”

Soil Engineering Geoservices are acutely awareof the environmentally sensitive nature of the Pass of Birnam to River Tay Crossing area and the challenges this presents e.g.the River Tay Special Area Conservation (SAC) and the proximity to settlements at Birnam, Dunkeld and Inver.

Soil Engineering propose to undertake the works with the following modern plant and equipment:

  • 6 No. Cable percussive Rigs
  • 5 No. Rotary drilling rigs

Testing of samples obtained will be carried out at Soil Engineering Geoservices in house geotechnical laboratory.

Site works are programmed to last 22 weeks.
