Plano de Trabalho para Fundação — crie com RAMSagent
A method statement for foundation covers excavation, sheet piling, piling, and base slabs. The document describes slope angles, lateral earth pressure, groundwater management, and heavy lifting — with a particular focus on collapse risk and documentation requirements according to HSE guidance.
RAMSagent suggests slope angles based on soil type and depth, and integrates lateral earth pressure into lifting plans for excavation machinery.
Riscos típicos para Plano de Trabalho — Fundação
| Risco | Descrição | Legislação | Gravidade |
|---|---|---|---|
| Collapse in Excavation | Excavations deeper than 1.25 m require shoring, sloping (at least 1:1 in stable soil, 1:1.5 in loose soil), or other support systems. No one is allowed in unprotected excavations. | AFS 2023:13, 5 kap | Crítica |
| Groundwater and Drowning | Pumped excavation bottoms can refill quickly during rainfall. Work near open water requires a rescue plan and life jackets in case of drowning risk. | AFS 2023:13, 5 kap | Alta |
| Collision with Excavation Machinery | Exclusion zones around excavation machinery must be at least 1.5 × reach. A signal person must maintain visibility with the operator during reversing and lifting. | AFS 2023:13, 8 kap | Alta |
| Culverts and Cables | Cable and pipe surveys using cable locators or project documentation are required before machine-driven work. Hand digging is necessary near unprotected lines. | AFS 2023:13, 5 kap | Alta |

Perguntas frequentes
- When is shoring required?
- For excavations deeper than 1.25 m that cannot be sloped, or where adjacent buildings/roads are affected. RAMSagent flags if shoring is needed based on projected depth.
- What is a rescue plan for excavation?
- It describes how a person can be evacuated in case of collapse, groundwater filling, or unconsciousness. According to HSE guidance, it must be available on site.
