The heave calculation, made as at 1 June 2015 using data from the CET report, indicated a heave risk of 6.5mm. This is considered to be very low. However, it was Mr Allen’s opinion that the subsequent downward movement of 34mm recorded to the garage by November 2017 would indicate a “real risk of heave” by the time the decision to underpin was taken.
