Services
Site Engineering
Our site engineering services deliver high-accuracy dimensional control using robotic total stations, GPS/GNSS, and digital levelling equipment. We translate design data into precise on-site implementations, ensuring compliance with project specifications. Our QA reporting system automatically generates accuracy documentation for seamless project handover.
Surface Modelling
We create digital terrain models from survey data to enable volumetric analysis critical for project planning. These models support pre-construction valuations and post-completion account preparation, integrating UAV-captured data for mining and infrastructure projects.
Automated Machine Control
Complex 3D surface models are installed onto automated guidance systems for construction machinery. Our team manages data preparation and troubleshooting across proprietary platforms, ensuring real-time accuracy during earthworks and grading operations.
Utility Mapping
PAS128-compliant utility mapping identifies subsurface infrastructure with precision. This service mitigates risks during excavation by providing detailed records of buried utilities, enhancing safety and project efficiency for civil engineering works.
Aerial Imaging Surveys
UAV technology captures high-resolution aerial data for topographical mapping and progress monitoring. This non-intrusive method provides rapid site coverage, supporting volumetric calculations and deformation analysis for large-scale infrastructure projects.
Questions
What surveying technologies does 4D CES use?
We utilise robotic total stations, GPS/GNSS, digital levelling equipment, and UAV drones for high-accuracy data collection and analysis.
Do you provide services outside the South West?
Our primary focus is the South West region, though we may consider select projects beyond this area based on specific requirements.
What is PAS128 compliance in utility mapping?
PAS128 is a UK standard specifying detection and verification methods for underground utility data, ensuring safety during excavation works.
How do you ensure accuracy in setting out?
Our integrated systems validate measurements in real-time, with automated QA reporting highlighting tolerances against design specifications during site operations.
Can you assist with volumetric calculations?
Yes, we generate digital terrain models for pre-construction valuations and post-project account preparation using UAV-captured survey data.
