Wrecclesham Landslip Repairs

Customer – Geoffrey Osborne Ltd.

Project duration – 4 months

When – September – December 2016

Type – Sheet piling, Earthworks, Gabion baskets

Overview:

After a landslip caused by heavy rain forced the closure of a stretch of railway line from Farnham to Alton in Hampshire, Suttle Projects was called in to assist with the emergency repair works.

The company was later awarded a permanent works contract to install gabion baskets (with stone supplied by Suttle Stone Quarries) for further reinforcement, as well as drainage on both sides, along with extensive earthworks.

Working alongside construction business Osborne, the project was scrutinised by Network Rail throughout, and a scoring system that sought to identify key safety criteria was being met was applied.

Projects identified key risks involved in the work, and established a number of innovative solutions including the installation of a propping system to accommodate traffic over a low weight bridge, slewing restrictors on equipment operated near power cables to physically prevent any collisions, an adjacent line opening (ALO) review while working at the top of an embankment, and a specialised trench support system design.

In addition, harness eyes were welded to sheet piles to solve the risks involved with working at height on an embankment. Network Rail considered the innovations and works worthy of its prestigious gold award, and demobilisation works were also awarded to Projects.

Network Rail awarded Suttle Projects with a gold star for its innovative approach to health and safety for working at height, and for its work as a whole. Projects maintained its relationship with Osborne, and by extension Network Rail, through their positive reception of the work.
