Information requested

Geotechnical reports are mentioned in the above referenced letter between the Transport Minister Graeme Dey MSP and Collette Stevenson MSP. The following was quoted:

“The geotechnical conditions between Busby and Hairmyres are challenging, and double-tracking would require significant earthworks to be undertaken, carrying a high degree of risk”.

I'm making an FOI request to receive copies of the reports that outline this statement please?
