Job Hazard Analysis for Foundation — create with RAMSagent
A risk assessment for foundations evaluates project risks during excavation, sheet piling, piling, and slab work. It includes risks of collapse, groundwater, cables/pipes, traffic, and heavy lifting in accordance with HSE guidance and CDM 2015.
RAMSagent uses geotechnical data and cable mapping to quantify risks before work begins.
Typical risks for Job Hazard Analysis — Foundation
| Risk | Description | Legal | Severity |
|---|---|---|---|
| Excavation | Collapse risk depends on soil type, depth, groundwater, and edge loading. Slope angles or sheet piling must be designed before excavation starts. | AFS 2023:13, 5 kap | Critical |
| Groundwater and Drowning | Excavation below groundwater level requires dewatering, a rescue plan, and sometimes life jackets for work near open water. | AFS 2023:13, 5 kap | High |
| Unprotected Utilities | Gas, electricity, and water lines underground must be mapped before excavation begins. Cable location services should be requested from utility owners. | AFS 2023:13, 5 kap | High |
| Traffic Near Excavation | Establishment vehicles, machinery, and third-party traffic can affect excavation edges. Barriers and traffic plans are necessary. | AFS 2023:13, 8 kap | Medium |
Applicable Regulations

Frequently Asked Questions
- What slope angle is required?
- At least 1:1 in stable soil and 1:1.5 in loose soil. In cases of uncertainty or deeper excavations, geotechnical data or sheet piling is required according to HSE guidance.
- How do I map underground utilities?
- Request cable and pipe location services from network owners (e.g., www.linedetection.co.uk). Documentation is included in the risk assessment.
