Understand what a Detailed Engineering Assessment is and when your building needs one.
A Detailed Engineering Assessment (DEA) is a thorough evaluation of an existing building to determine whether it is structurally safe.
When is a DEA needed?
- Older buildings with signs of distress such as cracks
- Buildings that will be extended or have floors added
- Change of use, for example converting residential to commercial
- Compliance requirements after new safety regulations
What the assessment involves
Data collection
Engineers review drawings, measure the structure and test material strength.
Structural analysis
The building is modelled and checked against current codes and expected loads.
Recommendations
The DEA report states whether the building is safe and, if needed, recommends retrofitting.
Why it matters
A DEA gives owners clear, evidence-based answers about safety and protects occupants.
