As part of the Sighthill development works in Glasgow, a new road bridge was constructed by AMCO off Keppochhill Drive and over the Railway line EGM1. This bridge was positioned at the same location of the old footbridge which had been previously demolished as part of Edinburgh Glasgow Railway Improvement Programme (EGIP).
This bridge will be used as one of the accesses into the £250m regeneration area in Sighthill.
MHB Consultants designed the earthwork tie-ins at the four corners. This consists of Maccaferri terramesh walls sitting on soil slopes stabilised via a combination of soil nailing and flexible facing.
Due to the limited space available near the cemetery wall corner, MHB Consultants also designed an anchored sheetpile wall to provide the transition into the original ground profile.
Our solution avoided the need to construct reinforced concrete wingwalls and is more environmentally friendly and cost effective.
Construction of the bridge and tie-ins has recently been completed with some photographs of the structure and works below.

We recently completed our 1000th job since MHB was founded in 2007. It’s been a bit of a journey – starting from a one man band freelancing in 2007, to 3 staff in our first office in a shared business centre, to 24 staff today in our St Enoch Square Glasgow office.
The jobs have ranged from fees of £100 to over £0.5 million with everything in between. We have expertise in temporary works, permanent works, bridges, tunnels, soil stabilisation, drainage schemes, railway platforms and lots more.
Thanks to all our past and current clients and we look forward to continued success, Cheers!
Friday celebrations (L-R): Alistair Gray, Gleb Borshchyev, George Marjane, Chris Miller, Graeme Edwards, Sean McDade, Craig McLeod, Damien Moore, Gillian Pettigrew, Mike Lauder, Amy Buchanan, Hendrie Barbour, Noosha Madjlessi, Michael Hynan.
As part of the Stirling/Dunblane/Alloa (SDA) electrification works, the existing footbridge at Stirling station between platforms 6 and 9 (which is listed) is to be removed and then reinstated.
The footbridge is to be removed and refurbished and will be returned to site in approximately 1 year.
When the footbridge is removed, temporary propping is required to the station building beams which are currently supported from the footbridge superstructure.
MHB designed the temporary propping to the station building façade, temporary footbridge foundations, temporary hoarding and piling platform to facilitate the removal of the footbridge and the installation of the permanent works.
The footbridge was removed on 2 September 2018.
The remaining works are ongoing but here are some pictures from the site to show the footbridge being lifted out for its makeover!

Over the past few weeks two new members of staff have joined us at MHB Consultants. These fresh faces are here to bolster our team and support our continued growth.
Chris Miller has just completed his honours degree in Civil Engineering at the University of Strathclyde. During his time at University he worked part time as a land surveyor, and as a student engineer in the construction industry during his summer breaks.
Noosha Madjlessi has recently finished her PhD in Civil Engineering at Heriot Watt University. She studied her MSc in Civil Engineering Structures at City University London and her BEng (Hons) at Cardiff University. She has 2 years post graduate experience in a multi-disciplinary firm of consulting engineers whilst working in Iran.
We welcome another new starter at MHB Consultants.
Sean is our newest bridge engineer, he will be working alongside the bridges design team supporting them on a variety of new contracts.
He graduated from the University of Glasgow in 2014 with a first class degree in Civil Engineering. He has 4 years of industry experience with the most recent being a role with AECOM. He comes to MHB with extensive technical knowledge in the form of production assessment and designs for bridges and analysis through the production of linear and non-linear models of existing structures.
We look forward to supporting Sean’s growth and development within the firm.
If you are interested in working with us please send an email to:
Alistair Gray has been promoted to Director, effective 17 July 2018. Alistair was the very first employee at MHB Consultants back in January 2010. Since then he has been instrumental in growing the civil engineering department, including our temporary works design and land surveying teams. He currently leads a team of ten engineers and surveyors.
Many congratulations to Alistair and we look forward to the next chapter !
MHB Client - CPMS – Principal Contractor
Ultimate Client – Network Rail
On behalf of CPMS, MHB undertook Topo Surveys of 11 no. station footbridges to support structural and condition assessments. The drawings were delivered in 3D AutoCAD.dwg format.
The topo survey of the footbridges required a mix of working during daytime in normal high street conditions and at night under track possession (times when there are no train movements). The client CPMS arranged possession times with Network Rail and provided a schedule from which MHB could plan additional day shift visits to allow efficient completion of the onsite survey works. Tracks, platform edges, track furniture and sections of the footbridge not accessible form the platform were surveyed under possession. During normal operating train times when survey work was being carried out no equipment was placed within 1.25m of the platform edge in accordance with Network Rail PTS.
The key challenge of the footbridge surveys was the intricacies of the structure and the requirement of multiple total station set ups to capture all aspects of the bridge. The works were undertaken using a Trimble S8 High Precision 1” total station. Angular Accuracy is accurate to 1” (0.0003°) with electronic distance measurement accurate to ± 1mm + 1ppm in prism mode and ± 3mm +2ppm in direct reading (reflector-less) mode. This is above the minimum standards for total station accuracy as outlined in section 5.9 of Network Rail Document NR_L3_TRK_3101 which states a minimum angular accuracy of ±2” and EDM accuracy of ±2 mm + 2 ppm. All observations on rails were taken with prism on a rail foot adaptor to get the inside running line which is 14mm below the head of the rail.
Before commencement on each site a reconnaissance was carried out to plan the optimum total station locations. These were positioned in areas which allowed large sections of the survey to be completed to minimise total number of set ups required, and thus possible introduction of error. Lines of sight were taken into consideration as well as safety of location and ensuring not to block or hinder public access during station operational hours.
The total station was set up over a survey nail and levelled to gravity. The instrument was levelled using electronic bubble until 3” or below in both pitch and roll was indicated. The compensator was switched on in case of any minor vibration from passing trains etc. All required survey control was set in from the initial set up. A base line longer than the extents of the site was selected from which GPS coordinates were observed using Trimble R6 dual frequency GNSS receiver with choke ring antenna. The completed survey could then be transformed to OS National Grid coordinates in Trimble Business Centre post-processing software.
Levels were taken on inside running line of rail track, platform edge, platform extents footpath edges and centres. On roads, top and bottom of kerb lines were taken along with road centre to ascertain camber. Building footprints were observed with levels taken either side of door openings. Soffit and cill levels were taken by reflectorless measurement on buildings and underside of bridges. Stairs were taken at front edge of each riser with levels on centre of walkways and landings. Ample points were observed to show the position and orientation of all service covers and street furniture. On completion of each set up observations were made back to the reference object to ensure that no drift greater than ± 0.1m in 100.00m had occurred within instrument position.
A MHB method statement for topographical survey and risk assessment was carried out for all sites and a tool box talk was conducted by staff immediately before commencement on site. A COSS briefing was attended in addition for nightshift works to highlight any other activities which may be going on along the line and when to be clear of tracks.
As the survey was carried out to the specifications detailed in Network Rail document NR/L3/TRK/3101 Topographic, engineering, land and measured building surveying guidelines the 3D CAD drawing is compliant to BIM level 3.
We are really pleased to have Scott Kennedy here with us as our Summer student for 2018.
Scott has already completed 4 years at Strathclyde University studying Civil and Environmental Engineering. During his time at MHB Consultants he hopes to gain valuable industry insights and get some hands-on site experience, and even an occasional nightshift with our senior engineers! We are lucky to have a flexible working environment, so we can ensure that Scott gets involved across a wide variety of projects.
After his summer placement has finished, Scott plans to further his studies at Glasgow University, taking on a Masters degree in Civil Engineering or Sustainable Energy.
