Geotechnical engineering services are an important part of Roughton's multi-disciplinary approach to road and highway engineering projects.
Regularly working in challenging terrains; mountainous, rocky, swampy, arid etc, it is the geotechnical element that provides some mitigation against the risk of design and construction issues arising in both the short-term (such as during construction) and long-term future of a highway. In these circumstances the resident engineer role on a design and construction supervision project, might be undertaken by a Geotechnical Engineer.
Geotechnical design is based on an understanding of site specific geological data and any known historical information. This might be gathered through a site visit and with reference to aerial photography. Issues are identified that may later affect a structural or highway engineering project, such as ground movement and subsidence, allowing mitigation measures to be taken, such as:
