Risk Assessment for Foundation — create with RAMSagent
A Job Hazard Analysis for foundation work assesses project risks during excavation, sheet piling, piling, and slab work. It covers collapse risk, groundwater, cables/pipes, traffic, and heavy lifting according to Canada Labour Code Part II.
RAMSagent uses geotechnical data and cable mapping to quantify risks before work begins.
Typical risks for Risk Assessment — Foundation
| Risk | Description | Legal | Severity |
|---|---|---|---|
| Excavation Collapse | Collapse risk depends on soil type, depth, groundwater, and edge load. Slope angle or sheet piling must be designed before excavation starts. | Canada Labour Code Part II | Critical |
| Groundwater and Drowning | Excavation below groundwater level requires dewatering, a rescue plan, and sometimes a life jacket for work near open water. | Canada Labour Code Part II | High |
| Unprotected Utilities | Gas, electrical, and water lines underground must be mapped before digging starts. Cable location requests are made to utility owners. | Canada Labour Code Part II | High |
| Traffic Near Excavation | Site vehicles, machinery, and third-party traffic can affect excavation edges. Barricades and a traffic plan are needed. | Canada Labour Code Part II | Medium |

Frequently Asked Questions
- What slope is required?
- At least 1:1 in firm soil and 1:1.5 in looser soil. If uncertain or for deeper trenches, geotechnical data or shoring is required according to COHSR.
- How do I map underground utilities?
- Order cable and pipe location services from network owners (e.g., ledningskollen.se). Documentation is included in the Job Hazard Analysis (JHA).
