Construction Cost Saving Through Adoption of IoT Applications in Concrete Works

Development of digital technologies and processes including Internet of Things (IoT) applications is central to the required transformation of the construction industry within the frame of Construction 4.0 concepts originated from the fourth industrial revolution Industry 4.0. The construction sector has vast potential to improve productivity and efficiency thanks to digitalization, innovative technologies and new construction techniques. The new tool Concremote, offered by multinational expert in solutions of formwork, uses digital sensors to measure the in-situ concrete maturity gradient and with this data it calculates early age strength. Being able to measure in real time the development of in-situ concrete maturity can reduce striking time and thus reduce cost of formwork. The aim of the case study is to demonstrate saving of formwork cost due reducing striking time through intended employment of the tool Concremote in construction of slabs. The cost of slab formwork was estimated in different variants of formwork striking times. For most variants of construction time and striking time, it was verified that the saving of the formwork cost due reducing striking time is higher than cost of the Concremote employment in the referenced construction.
