Project Overview
The Tallaght / Clondalkin to City Centre Core Bus Corridors of the CBC Infrastructure Works measures approximately 15.5km with an additional offline cycling facility approximately 3.9km in length consisting of two sections, namely the Tallaght to City Centre section and the Clondalkin to Drimnagh section.
Project Brief
Create a 3d model of all subsurface utilities and features of the entire route to assist in the design and programming of the project.
Our Approach
To create an accurate 3d model of such a large area, we carried out a full PAS128 quality level B utility survey of the entire route. We utilised our Stream DP mobile mapping GPR, to allow us to get full coverage of the route and minimize the disruption to traffic in the area.
- Liaise with all utility providers and stakeholders in the area.
- Design and implement adequate traffic management plans for client approval.
- Deploy 4 x utility survey teams on site.
- Utilise our Stream DP mobile mapping GPR to cover the entire route.
- 2,850 manholes surveyed.
- Post process GPR and survey data into a 3D model.
Results
The entire route was successfully delivered on time and to the desired quality levels. This allowed our client plan and mitigated the risks of utility clashes on site.
