London civil structural engineering

About us. 

Established to provide innovative and practical civil engineering solutions.

OTB was specifically established in 2005 to provide the operators of London’s underground railway with innovative civil and transportation engineering solutions for growing and maintaining their underground rail infrastructure


Set up by a small group of leading practitioners, we have since grown to become a dynamic international business. Our operations are global: in the past 6 years, we have delivered projects in 13 different countries. And, as a growing business, we aim to provide a wider range of specialist services and greater depth of resource both regionally and internationally. 


We opened our UK regional office close to Chester in 2010. In January 2016 we moved our growing northern office to a larger space in Northwich, to support the northern powerhouse.
