Construction site safety: accident, barriers and liability

A person who creates or controls a source of danger must take reasonable safety measures. On construction sites this may concern the client, contractor, subcontractors and, depending on role, coordinators.

The duty is not a rigid checklist. It depends on the type of danger, visibility, access and foreseeable traffic.

A concrete risk assessment of the site matters more than a general clause in the contract.

Client and contractor may have different tasks. The party actually working on site often controls different risks than the commissioning client.

Contractual allocation matters, but may not be enough. If a danger is visible, inaction can become problematic even for parties not performing the specific work.

The BauKG mainly concerns coordination and safety on construction sites. Civil liability under the ABGB must be assessed separately.

After an accident, sites change quickly. Barriers are added, materials are moved and access routes change.

Photos, videos, witness names, weather, lighting, time, access situation and exact accident location should be recorded quickly.

Insurers, site management and involved firms should be informed without premature admissions of liability.

Before the site starts, define who keeps routes clear, checks barriers, places warnings and reports safety defects.

Where several trades work together, clear reporting lines are needed. Otherwise everyone may later point only to their own section.

Minutes and regular site inspections help prove duties and actual control.

After personal injury or property damage, liability insurance, construction insurance and legal expenses cover should be reviewed.

For injured parties, the evidence question matters: who was responsible, what was visible and which measure would have prevented the damage?

For clients and contractors, preserving documents and clarifying internal responsibility is central.
