Survey & Engineering Projects (SEP) has announced the launch of a new survey business, SEP Geophysical.

The company brings expertise and experience in geophysical land surveys and associated data processing to support UK public and private sector clients. SEP Geophysical joins the existing multidiscipline SEP group, which provides services to the infrastructure, energy, construction, utilities and telecommunications sectors.

SEP is a multidiscipline land and marine survey business operating throughout the UK. The company has a strong track record of providing high-quality products and services to support civil, geotechnical and environmental engineering projects and objectives. SEP's Directors have a wide range of international experience and expertise, each with a minimum of 20 years' survey industry experience. The company is recognised for its ability to coordinate complex surveys.

SEP Director Mark Hayes said:

"SEP's existing survey teams have earned an enviable reputation for providing high-quality data and analysis to support all types of projects across the UK. The launch of SEP Geophysical means we can now offer a broader range of expert geophysical disciplines on a fully supported basis, to help ensure all our clients' geophysical objectives are achieved. It also means the companies in the SEP Group can more easily support each other's existing projects by providing complementary services."
