Topographic Survey | Darwen
Introduction
Location: Darwen, Lancashire
Client: Confidential
Sector: Commercial Development
Turnaround: 2 days
Deliverables: 2D & 3D CAD, PDF, Control Point Package with Images
Project Overview
Brookes Geospatial was appointed to carry out a topographic survey in Darwen to support the initial stages of a planned commercial development. The client required a fast, reliable land survey to enable architects and consultants to begin design work with confidence.
The survey focused on capturing the existing topography, surrounding buildings and boundaries, and a newly constructed access route on site. Due to the time-sensitive nature of the project, we delivered all outputs within 48 hours of instruction.
Scope of Work
Our topographic survey included:
Full site level mapping including contours and breaklines
Recording of site boundaries, surrounding structures, and existing features
Mapping of the newly installed road and its position within the wider site context
Establishment of a survey control network for future setting-out work
Survey Methodology
To achieve high accuracy and efficiency, we used a combined workflow of:
Leica GNSS
Leica TS16 Total Station and Traverse Kit
LSS Software to carry out a Bowditch-adjusted traverse
Drafting in AutoCAD to deliver clear and usable CAD outputs in both 2D and 3D
We also provided the client with:
Retro targets installed and tied into the adjusted control network
A photo register of control points to assist contractors with referencing in future works
Results & Impact
All deliverables were issued within 2 working days, allowing the design team to move forward without delay. The high-quality survey data gave a clear understanding of the site's topography and features, reducing risk during the design and construction planning phases.
Our integrated control network and supporting imagery also provided a solid foundation for any future site setting-out, saving time and increasing accuracy for downstream teams.
