Fugro will start work on its third contract for Transport Scotland on the A9 dualling programme later this month.
The 26-week £1.3M award includes integrated geotechnical and geophysical data collection along 23km of road corridor - Glen Garry to Dalwhinnie and Dalwhinnie to Crubenmore.
A 12-week programme of site work will include 48 rotary boreholes to undertake 290m of coring and 334m of open hole drilling, plus a further seven sonic boreholes for soil and rock coring to over 70 metres in depth.
The firm will also undertake almost 100 machine dug trial pits, geotechnical soil and rock testing, contamination testing, peat probing, wireline geophysics, surface geophysics, post fieldwork monitoring and reporting.
Fugro’s estimating manager Neale Davies said: “Fugro is delighted to have been awarded a third ground investigation on this prestigious project through some of Scotland’s most picturesque mountain scenery.
”We look forward to continuing our close work with Transport Scotland and their engineer, CH2M Fairhurst Joint Venture, in order to meet, or even exceed, their expectations” he added.
With its latest package, Fugro will have undertaken either preliminary or advanced site investigations across more than half of the overall 129km project.
In 2015, Fugro completed ground investigations of superficial deposits and bedrock along a 46-kilometre section between the Pass of Birnam and Glen Garry.
In addition last year, Fugro carried out geotechnical work to characterise ground conditions for a 14.5km section from Tay Crossing to Killiecrankie within the project’s southern section.
A9 dualling upgrade
The Scottish Government’s £3bn dualling programme will see eleven sections of the A9 between Perth and Inverness upgraded to dual carriageway by 2025.
The first completed stretch, 7.5km between Kincraig and Dalraddy, opened in September.
