Assistance was required at a waste bunker at Earls Gate Energy Centre in Grangemouth, Scotland, to provide temporary support for safe access to complete ongoing progress.
MGF became involved with the project after meeting with the contractor, Clugston Construction. Discussions took place surrounding the initial design and how external factors had the potential to affect the end scheme.
‘We sat down with their designers and through numerous phone calls and meetings we came up with a temporary work solution which sped up the process.’

Tackling unsafe ground conditions with one of the strongest hydraulic struts on the shoring market
The MGF Major Projects team provided an initial design of one frame for the excavation, but due to issues with Deep Soil Mixing installation, this was amended to a two-frame solution. As excavation works progressed, excessive sheet movement occurred due to poor ground conditions. A third frame was added to reduce any additional movement.
The final solution consisted of 15m long sheet piles containing three levels of propping comprising MGF 406UC Tank Brace supported by 8 No. corner braces. The innovative element of this project was the inclusion of MGF’s 350-tonne hydraulic strut, used because of the high loads and the unstable ground conditions.
The 350-tonne hydraulic strut is one of the strongest in the shoring market.
The solution incorporated MGF’s integral prop load monitoring hardware. Prop load monitoring enabled MGF, the contractor and designers to monitor the live loading on the prop through an online portal. This provided significant benefits, as it was possible to assess how the excavation was behaving through the pressures induced in the hydraulic struts.
The overall excavation was 28 metres x 24 metres x 7.8 metres deep.
Keeping in constant contact with the contractor allowed MGF to respond quickly and efficiently when any issues arose. By having members of the team on-site, MGF were on hand to assist in any way necessary.
A recent update on the project showed that the dig and pile cropping is now complete with rebar installation at approximately 80%, with plans to pour the concrete base and have the bottom frame removed sometime after.
Our 406UC Brace has been designed to brace large and deep cofferdams, these are frequently used on major basement and …
