BRT Scheme for NTA
About This Project
This scheme will serve the busy corridor between Swords and the City Centre. Murphy Surveys were required to carry out a topographical survey of the above ground infrastructure & non-invasive mapping of existing underground utilities. The purpose of the survey was to facilitate the development of the design of the relocation of existing utility services which may be required to be diverted or protected during the course of the BRT Scheme Construction Works. The results of the survey were relied on for the estimation of quantities for the main contract for the BRT Scheme Project.
• A full topographical survey of the proposed route and the investigation and mapping of all surface and sub-surface utilities and utility apparatus, using nondestructive methods
• The investigation and mapping of all surface and sub-surface utilities and utility apparatus within building structures and basements, using non-destructive methods
• Liaison with the various authorities, utility service providers and landowners
• The implementation of temporary traffic management arrangements
• The confirmation and verification of the results of the survey by means of the excavation of a number of slit trenches within the scope of the survey boundary
• The preparation of digital survey drawings and a utilities database
Operation/Safety Interfaces present in project
Murphy Surveys carried out all works on site during the night. This involved implementing a traffic management plan, obtaining work permits from Dublin City Council and liaising with various utility providers and an Garda Siochana. The survey objective was achieved utilising various techniques such as sonde surveys, radio detection surveys, ground penetrating radar surveys and any existing records that were available.
