Scotrail Abellio have an ongoing programme to improve cycle facilities across the Scottish Rail Network. This is part of a vision for a major shift in journey type; away from cars and towards public transport, cycling and walking. As part of this programme they have undertaken to provide 3500 extra cycle spaces within the first 3 years of their franchise. The work is being implemented in a number of tranches throughout this period. MHB have carried out the design of Phases 5 and 6 of the scheme, which involves detailed design of cycle racks at 15 stations, mainly in the central belt of Scotland. The racks themselves are generally 2 tier to increase capacity within a small footprint area. The supplier is a Dutch firm, Falco, who bring with them extensive experience from the Netherlands where a much higher proportion of journeys are made by cycling. MHB services on the project included topographical surveys, foundation design and principal designer services. Partners on the project included LH Architecture who carried out listed building consents at Troon Station, and Principal Contractor Luddon who carried out construction works.
We are happy to welcome our new engineering geologist, Dhugal McQuistan, to the MHB team. Dhugal has a degree in Geology from Edinburgh University and an MSc in Applied Geotechnics from the Cambourne School of Mines at Exeter University.
As part of Scottish and Southern Energy’s ongoing works at the new Melgarve Sub-Station near Laggan, MHB have carried out a number of temporary works designs for the main contractor, BAM Nuttall. These have included assessments of abnormal loadings on two existing bridges along the access route to check their ability to carry transformers into the worksite. As well as this, MHB designed the foundations for a 50m span temporary structure across the River Spey. This was required to support a vehicle carrying transformer units, with a total weight of 197 tonnes. The temporary bridge superstructure was supplied by Mabey and was launched from a levelled platform area and supported on a series of roller bearings and reinforced concrete pad bases. The launch was carried out in February 17. MHB services on the project included assessment of ground conditions and detailed design of the foundations.

Amy Buchanan joined MHB in March 2017 as a Technician in our CAD department. She has a BSc in Environmental Civil Engineering and 6 years experience having worked with Amey, Buro Happold and BAM Nuttall.
The railway line at Lochburn, in Lambill, Glasgow was affected by a landslip on 4 April 17 at the site of an existing footbridge. One of the bridge retaining walls had collapsed with debris including masonry and soil lying on the track. This resulted in the cancellation of services between Glasgow and Crianlarich. An emergency contract was set up to remove the bridge and reopen the line as quickly as possible. A 500T crane was procured by the contractor, AMCO, and MHB were commissioned to carry out the crane foundation design. The general area is affected by historic coal and ironstone workings and part of the check included an assessment of the extent of the workings and whether they would impact on the crane pad. The proposed foundation pad comprised rock-fill reinforced with layers of Geogrid material, and loadings on the ground were reduced further by a grid of heavy timber mats. The design work was completed at short notice, and the crane lift was successfully carried out on 8 April 17.
