Allington Lane Embankment Stabilisation
Client: Osborne
Value: £1.3m

The works comprised the stabilization of the embankment at Allington Lane, Eastleigh, where we are the main earthworks supplier for Osborne. The contract was delivered under Osborne’s MFF with Network Rail. The works included installation of sheet piles on both sides of the embankment over a length of approximately 160m, re-grading of the embankment and installation of drainage and fencing. The works were carried out on both sides of the rail track simultaneously.

During the contract, 9.5m long sheet piles were installed whilst the rail tracks remained operational with trains running at 70mph. An open line working procedure was developed working in partnership with Osborne and approved by Network Rail.

The sheet piles were installed using a Movax attachment that made the open line working possible and safe and also reduced installation time for the sheet piling element.

Over 14,000T of material was imported to site. The site team value engineered the project and the construction methodology and achieved a zero waste percentage of materials off site by incorporating all the temporary materials into the permanent works, subsequently reducing CO² emissions on site.

The project received the divisional Right Works Award for high standards in site and works management.

These works are to stabilise a cutting and comprise the installation of soil anchors and rock netting, regrading the slopes and the removal of vegetation.

There are a number of challenges associated with the project including working adjacent to the live railway, rope access works, dealing with asbestos, overhead power lines and the presence of badger setts in a protected woodland setting.

The cutting slope exceeds 35 degrees with exposed sandstone beds and boulders likely to have come from earlier rock falls of undermined bedrock.
