Inspection and Diagnosis

NCREP performs inspection and diagnosis actions on constructions. Although the two have different objectives, they complement each other and, in the framework of NCREP, they should be inseparable. The Inspection corresponds to the survey phase, namely to the material and geometric assessment and damage survey of the construction elements, in particular, of those of structural nature. During this phase NCREP performs also an historical investigation and (or) research on the past of a construction whenever the circumstances demand it. Such investigation aims studying and evaluating the constructions’ evolution and transformation, namely the interventions to which they were submitted in the past, being used as a support diagnosis tool.

The Diagnosis takes the information of the historical investigation and of the inspection, and it evaluates the performance of the construction and the importance, extent and cause of damage. It aims assessing the current conservation and safety condition of the structural elements.
NCREP uses multiple complementary means of analyses during inspection and diagnosis actions, particularly on-site, to complement visual assessment. These are, essentially, simulation and experimental tools that are used whenever the complexity of the problem demands it.
The knowledge gathered through these actions is fundamental for the definition of solution and intervention strategies that are effectively directed to solve the constructions’ weaknesses and, simultaneously, have reduced intrusion levels. This approach demands a deep knowledge on the materials and experience on the use and interpretation of results of numerical and experimental tolls.
