Expert report for offices building due to strength reduction of supplied concrete
2019-2020
CERTIS

Certis, the construction company building the project, requested an expert report on the structure executed, for which a reduction in resistance was foreseen, due to the non-conformity of acceptance of several batches of concrete.

Windmill's mission is to evaluate, at the level of structural safety, the concrete structure of the office building already built, and to establish a plan of action based on this analysis.

To achieve this, a study of the statistical sampling and population parameters of the concrete was carried out. By means of the descriptive statistics, these parameters were obtained and a normal curve representing them was inferred by the maximum likelihood method.

Once the resistance of the concrete was estimated,  we evaluated the various structural elements already executed that were affected by the batches and that did not comply.
