Sunderland Bridge Rising Main

Project Overview: Three60 Mapping was commissioned by ESH Stantec to undertake comprehensive 2D and 3D PAS128 utility and topographical surveys along a 3km urban route for the Sunderland Bridge Rising Main project.

Objectives:

• Deliver accurate and detailed utility and topographical surveys to support design and route planning.
• Minimise operational risks and reduce the impact on traffic flow during surveying.
• Provide reliable data to facilitate informed decision-making during design and construction phases.

Approach and Methodology: The project involved extensive surveying along an active urban highway. A high-definition 3D laser scan using the Leica RTC360 was conducted to capture precise site conditions, supplemented by traditional survey techniques and the establishment of a robust survey control network. For underground utility mapping, our PAS128 QL-B M3P survey utilised Vivax Vloc 3 Pro CAT and the advanced Leica Stream UP vehicular-mounted multi-array Ground Penetrating Radar (GPR) system.

Challenges and Solutions:

• Urban Highway Constraints: To overcome the logistical challenges posed by working on an active highway, our team employed advanced laser scanning technology to significantly reduce personnel exposure on the carriageway.
• Traffic Management: Implementing a vehicular-mounted GPR system allowed night-time data collection during low-traffic periods, greatly minimising disruption and eliminating the need for extensive daytime traffic management measures.

Key Deliverables:

• PAS128 QL-B M3P survey outputs delivered in 2D/3D AutoCAD DWG/PDF formats.
• Comprehensive topographical survey drawings provided in 2D/3D AutoCAD DWG/PDF formats.

Results and Benefits: ESH Stantec received highly accurate topographical and utility survey data, enabling efficient design planning and risk mitigation for the rising main project. Utilising our innovative methodologies resulted in substantial reductions in survey duration, costs, and carbon emissions, demonstrating clear operational and environmental benefits

Client Testimonial

“Esh-Stantec have worked closely with 360 for the last 10 years, delivering data collection for the Northumbrian Water Framework Design Teams, we have always found them to be reliable, flexible and team players.

As well as standard survey deliverables such as Topographical, Utility, Drone & 3D Surveys etc., they have worked with us to enable multi-disciplinary surveys with other specialist contractors which involved an innovative approach to survey works within confined spaces environments.

We consider 360 as one of our key delivery partners and look forward to working with them to deliver our current and future framework requirements.’’
