MGL are a highly experienced civil engineering contractor with specialist expertise and core competency in major earthworks, temporary and permanent roads infrastructure, quarrying and mobile aggregate processing, marine rock
armour construction and underground cabling infrastructure. Based at Lairgandour near to our Midlairgs Quarry, this
recent acquisition will allow us to target larger civil engineering projects and strengthen our offerings to the wider construction sector.

As part of SSEN’s Argyll Reinforcement Project, MGL have been awarded the earthworks platform for the An Suidhe North GIS Substation, and the Workers Camp at Lochgilphead, by Balfour Beatty. MGL started the main works in March, and with a programme duration of 40 weeks, should be complete by the end of this year. The construction of the substation platform requires the reopening of the redundant Forestry Land Scotland Auchindrain Borrow Pit (BP), which is located within 3km of the new substation location. The BP works involve drilling and blasting, and processing of circa 175,000t of crusher run materials.

The earthworks for the substation platform, include the removal of peat overburden (circa 20,000m3), which have to be deposited within constructed peat containment cells. The site has an element of cut to fill, including rock excavation and removal, prior to the placing of the aggregates from the BP. In addition, the earthworks scope includes drainage and attenuation, the construction of an access road, a maintenance track, and the supply of aggregates for a reinforced soil wall. MGL are also undertaking earthwork contracts with Global Infrastructure on the Keith 132kV Substation upgrade and Compass Building and Construction Services at Campbells Farm Phase 6 in Broadford, Skye.
