Trial pits, slit trenches, and service location surveys — proving clear corridor for EPC clients on infrastructure projects across the UK.
Before any infrastructure project breaks ground, the corridor needs to be proven clear. AIM delivers comprehensive site investigation — trial pits, slit trenches, and service location surveys — with full 3D point cloud capture, detailed reporting, and fast turnaround. Our EPC clients get the certainty they need to programme works and manage risk from day one.
Each trial pit is scanned and processed into an interactive 3D point cloud — giving the design team a permanent, measurable digital record of what was found below ground. Pan, zoom, and rotate to inspect the excavation from any angle.

AIM's site investigation service is designed around what EPC contractors and utility clients actually need — reliable data, fast turnaround, and reporting that feeds straight into the design process.
Machine and hand-dug excavations for service location, ground investigation, and corridor clearance verification on live infrastructure routes.
Positive identification and recording of all underground services — utilities, drainage, telecoms — with depth, diameter, material, and condition logging.
Every excavation photographed and processed into an interactive 3D model — a permanent digital record the client can revisit at any stage of the project.
Full trial pit reports with dimensioned plans, sections, photographic records, and GPS data — formatted to client or principal contractor standards.
Delivering the evidence EPC clients need to confirm a corridor is clear before major works begin — reducing programme risk and avoiding costly rework.
Mobilisation within days, not weeks. Reporting delivered promptly with 3D models processed and shared via secure link for immediate design team access.
Client provides the SI schedule — service types to locate, corridor limits, and required depths. We review, clarify, and programme.
Crew on site with plant, hand tools, and detection equipment. Trial pits dug to specification with all services positively identified.
Photographic survey, GPS recording, and 3D point cloud scan of each excavation. Full trial pit form completed on site by the team leader.
Trial pit reports compiled with plans, sections, and photo records. 3D models processed and shared. Reinstatement completed to specification.
