Caracterização do comportamento estrutural
            
        - Analysis and       monitoring of vibrations in structures 
- Quality and durability assessment for cement       pavements
- Pull-out test on bonded plates 
- Evaluation of the integrity of concrete piles by sonic tests. 
- Termographic survey
- Measurement of the superficial moisture in       walls 
- Monitoring of the evaluation of cracks and other structural       movements
- Boroscopic inspection of cavities and cracks
Apart from these and other “in situ”  techniques, Oz collects samples for laboratory testing techniques, in  particular the following most frequent tests:
      
        - Petrographic examination of concretes and mortars; 
- Control  of the compressive strength of the concrete one from cores
