The project required the contractor to excavate within 25m of Beaumaris Castle – a UNESCO World Heritage Site and one of the best examples of 13th and 14th century architecture in Europe attracting over 100,000 visitors last year.

Faced with the challenge of installing 600m of 1.5m diameter polypipe in 6m sections between existing manholes, John Kelly Construction spent time researching the products available on the market, before finding that MGF’s High Clearance Trench Boxes were ideal for the job.

“Beaumaris’ most recent floods in 2017 was the catalyst that something needed to be done regarding the surface water drainage system. MGF became involved to supply the excavation support equipment to alleviate the threat of flooding to protect the natural beauty and tourism trade in the area”.

The Solution

The 7m x 2.9m wide High Clearance Trench Boxes coupled with Top Boxes saved time and money to the contractor when compared to sheets and frames. The strength of the box allows suitability and capability of going to 5m depth and having high clearance struts on both ends of the box allows access at both sides – ideal for installing larger diameter pipes and tanks.

MGF’s stock logistics team sourced the kit from out Dartford Depot and coordinated delivery to site from the Astley Depot with three artics and two 15t wagons to ensure the order was met.
