The construction industry continues to be a hotbed of innovation, with activity driven by an increased focus on environmental sustainability and workplace safety, and the growing importance of technologies such as robotics and the Internet of Things (IoT). In the last three years alone, there have been over 248,000 patents filed and granted in the construction industry, according to GlobalData’s report on Modular construction in Construction: Reinforced prestressed construction. Buy the report here.

According to GlobalData’s Technology Foresights, which uses over 179,000 patents to analyse innovation intensity for the construction industry, there are 80+ innovation areas that will shape the future of the industry.

Reinforced prestressed construction is a key innovation area in modular construction

Reinforced prestressed construction uses prestressed concrete as a structural material, allowing the counteraction of the stresses that will occur when the structure is subject to a load. Prestressed concrete combines the compressive strength of concrete with the tensile strength of steel.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies.  According to GlobalData, there are 20+ companies, spanning technology vendors, established construction companies, and up-and-coming start-ups engaged in the development and application of reinforced prestressed construction.

Key players in reinforced prestressed construction – a disruptive innovation in the construction industry

‘Application diversity’ measures the number of different applications identified for each relevant patent and broadly splits companies into either ‘niche’ or ‘diversified’ innovators.

‘Geographic reach’ refers to the number of different countries each relevant patent is registered in and reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
