Heathrow tunnel refurbishment

Technics, appointed by BAM Nuttall Ltd. has undertaken topographical and utility surveys at Heathrow Airport.

Involved in the project since July 2014, Technics has provided detailed data and analysis to identify utilities and buried services on the site, and support the improvement of the entrance tunnels to the main terminal area of the airport.

The survey results helped limit potential risks during the project and helped prevent any disruption to services, enabling Heathrow to make upgrade improvements to the tunnel. The data also supported the team in its installation of new underground services and improvements to the access road to the main terminal area.

This is one of Technics’ first projects, and the first major project at Heathrow, that has been delivered in line with PAS 128 Surveys.

Published last year, PAS 128 is a new specification for underground utility detection, verification and location, ensuring that the survey a client chooses is being undertaken to the highest professional specification.

It’s a specification that Technics was heavily involved in last year, supporting the Chartered Institution of Civil Engineers, Transport for London and Highway England, in which they advised on how standardisation should and could be progressed.

This project forms part of Technics wider work at Heathrow.
