Howard Civil Engineering were contracted by Wates Group Limited to undertake the groundworks and civils package for a new Leeds City Council housing project. As part of these works a 60 linear metre culvert was required and NTS (UK) were engaged to design and supply the excavation support system to allow the culvert installation.
The works were carried out with requirements to ensure maximum working space and clearance to allow the culvert installation. The depths ranged from 3.4m – 3.8m with a minimum 2.3m under strut clearance required. As the culvert run was to be installed within a sloping the shoring system had to provide both flexibility and strut position adjustment.
NTS (UK) designed and supplied a 30m run of the unique single slide rail shoring system which was to be ‘leap frogged’ and re-used to complete the full 60m requirement. The system incorporates rolling struts which allow vertical adjustment and 6m plates which provided maximum clearance between struts, with the rolling struts also positioned to allow for a maximum 3.0m under strut clearance, both something which cannot be achieved with traditional box systems.
