After installation and commissioning, we conduct post-commissioning surveys which are essential to ascertain the integrity of all project systems for the duration of the design life. Also, these studies help our client to take remedial measures in case any flaw is detected. The post commissioning study is largely the same as pre commissioning, the key difference is the intention of the survey which becomes focused on the functionality against expected degradation and the remedial action required in the post Cx survey, whereas the pre Cx survey is focused on initial performance against design and the requirements to achieve these targets.
