Project Description

SCOPE OF WORKS: 200 linear metre soil nailed slope up to 7m sprayed with rigid concrete facing and 40 linear metre king post wall

CLIENT: IBO Construction Ltd

CONTRACT: Design and build


In preparation for a new cold storage warehouse south-east of Chesterfield, Aarsleff were contracted by IBO Construction Ltd to design and install a 200 linear metre soil nailed slope with a sprayed concrete ‘rigid’ facing and 40 linear metres of a king post retaining wall. Challenging design and complex logistics have made this a keystone project, with it being one of the largest soil nailing projects delivered by Aarsleff in recent years. Our design engineers were faced with many complex design elements including assessment of rock stability, soil nail design, groundwater control, and producing high quality construction drawings. The scheme, from tender, to design, to installation, is a prime example of Aarsleff’s ability to add value for our clients at every stage, delivering trusted solutions to even the most complex of projects.

One of the key parts of the logistics of this project was that the level of the development platform was considerably lower than the existing ground level on site, and therefore, the soil nails were installed on slopes excavated at 80 degrees up to 7m high, which is higher than the average two storey house. To ensure stability of the slope as it was excavated, Aarsleff had to work closely with our client to install 5 rows of soil nails in a top-down sequence as the excavation progressed. Soil nails of up to 7m long were installed in a grid-pattern at 1.5m centres before the face was reinforced with a structural steel mesh and sprayed concrete facing.
