These measures aim to boost energy efficiency, reduce carbon emissions, and enhance indoor air quality.

The global construction market is experiencing increased demand, propelled by the time-saving benefits of technological advancements such as Building Information Modeling (BIM), laser scanning, 3D printing, and smart building systems. Stakeholders including contractors and builders are integrating digital technologies like artificial intelligence (AI), advanced analytics (AA), and machine learning (ML) to achieve better business results and address challenges such as labour shortages, further bolstering the market's growth prospects.
