Abstract: Super speciality hospitals on crowded urban sites rarely open on time, yet most delay studies rank causes from opinion alone. This paper links a practitioner survey with the planning record of a delayed project. Twenty-seven delay factors, drawn from recent literature and a pilot study, were rated on a five-point scale by 19 professionals working on hospital and high-rise projects in the Mumbai Metropolitan Region (513 ratings, Cronbach's α =...

Abstract: Many low-rise reinforced concrete (RC) buildings in coastal Mumbai reach the middle of their service life with corroded column bars, spalled cover and concrete grades that are now below the code minimum. This paper examines a three-storey RC cold-storage building in Andheri built with M15 concrete and 225 mm × 525 mm columns. A staged protocol is followed, combining visual survey, rebound hammer and ultrasonic pulse velocity (UPV) testing....
