No idea, as I have already explained; I am not a structural engineer, however, Atkins are and you haven't provided me with any reason to doubt the validity of their findings other than to backtrack on your claims regarding the content of their report and point out they cannot possibly conclude carbonation has occurred from a visual inspection. Obviously they feel confident in their own expertise that they can assess that from the investigation they carried out.The only mention of carbonation of the concrete is in the summary, as someone who has worked on several projects were concrete and steel carbonisation is an issue that we have to deal with, how would you establish that carbonation has taken place without taking a test ?
There is no mention of carbonation tests in the report therefore it can’t be proven to be true, if there’s no test you cannot surmise that carbonation is present…I used to work for Atkins in Leeds back in the day and was part of a team doing conditions surveys in old buildings, a test would always be required, if a doctor said you’ve broken your leg would you take his word or ask for an x-ray.
Yes I’m doubling down on the fact that you can’t say with certainty that carbonation is present without doing phenolphthalein or other tests, a binocular and drone survey would not give you the necessary level of detail to give anything beyond a rough approximation of shelf life and internal deterioration.
