As members of the Association of Geotechnical and Geoenvironmental Specialists (AGS), LSTC Engineers have the knowledge and experience to undertake desk studies, and to design and undertake detailed ground investigations.
Within LSTC, the ground engineering group specialises in ground investigation and foundation designs for overhead line towers and substations, rail crossings and highways together with foundation condition inspections. LSTC staff are experienced in all aspects of this field, having worked on numerous power transmission, rail, highways and engineering projects from feasibility through to final design.
For ground investigation schemes, a desk study assessment is made of the likely ground conditions from past records or geological maps to provide a cost based on using the most appropriate investigation techniques. Following the site work, an interpretative report with foundation recommendations is provided. In addition, a contamination assessment is included to provide guidance on the health and safety risk to ground workers and a landfill classification for the disposal of excess excavated material.
Foundation condition assessments generally involve a visual inspection from ground level followed by staged excavations to inspect and test the foundation condition of selected towers.
Non-destructive testing techniques are also available. From the results, an assessment can be made of the likely overall condition of the tower foundations for the partial or full length of an overhead line. In addition, our Engineers can assess the capacity of the foundation should this be required for any upgrading schemes.
LSTC can provide detailed design of foundations for construction.
Our experts are fully qualified to diagnose foundation problems and advise on the most effective and economic remedial and/or strengthening measures.
