Project: Fenchurch Street, City of London
Works: Utility Mapping Survey
Description Mantra Services were commissioned to undertake a PAS 128 survey in the vicinity of Fenchurch Street for the proposed demolition of a city block and subsequent £400million development of the project colloquially known as 'Gotham City'. After our initial reconnaissance we decided this project would require a PAS128:2014 survey level of M4P to successfully map the extremely complex underground network of pipes and cables. Due to nature of the location, we were unable to proceed with any work until permission had been granted for traffic management by the City of London. This required intense negotiation and effective communication to arrange dates and times which would create minimal disruption to this densely populated area. It was decided much of the work would need to be undertaken out of hours at nights or weekends. The post processing procedure involved using 3D GPR post processing to provide the most accurate information available for this high profile project.
