Working as a sub-consultant to Carillion, MHB carried out the design of embankment stabilisation works at Dun Falloch on the West Highland Line, near Crianlarich. An existing gabion retaining wall was showing signs of movement and required remedial works to ensure the safety of the railway line. Following a site investigation and assessment, it was concluded that the wall was failing due to surcharge loadings from the embankment due to an increase in ballast depth over the years. MHB carried out the design of a ground anchorage scheme, where Ischbeck self- drilling anchors were installed through the gabions to provide the necessary stabilising force to ensure stability. This also allowed the wall to be heightened as required to retain the embankment side slopes.
MHB have recently completed temporary works designs associated with the £60m revamp of Queen Street Tunnel and Station. Morgan Sindall carried out the construction works in a 20 week shutdown of the station and tunnel over the summer of 2016. The works were successfully completed and the station was re opened and handed back to the client a week ahead of programme
The works carried out by MHB Consultants included:

MHB Consultants have been commissioned by Arcadis to carry out design work on the Holytown to Midcalder Electrification Project. The scheme forms part of the Government’s rolling programme of electrification in Scotland’s railway infrastructure. MHB’s role in the scheme includes design work for the foundations of the 1500 electrification masts required along the 36 km route. Work commenced at Early Contractor Involvement (ECI) phase working with Carillion Powerlines and Network Rail to develop outline foundation designs and site investigation strategy. This has continued through to development of detailed designs in conjunction with our design partner, Arcadis. More details of the Government's electrification programme can be found here.
We are pleased to announce that as of July 2016 our graduate training scheme has been approved by the Institution of Civil Engineers.
MHB were commissioned by AMCO to carry out design works on Sandyford Street Railway Bridge near Finnieston in Glasgow. The existing lattice girder structure is over 100 years old and under strength for the current level of rail traffic. In addition the bridge had numerous corroded elements which required repair due to water ingress. The works involved looking at various repair options including replacing the bridge with a new structure, infilling it to render it redundant or repairing and strengthening the existing bridge. Following an options report by MHB, the scheme selected was to repair and strengthen the bridge. Works involved strengthening of the main trusses, various repairs to corroded members, installation of a new timber deck, waterproofing and full repainting. The works were completed early 2016.
