Chemical Technologies Enhancing Construction Resilience

The Kolkata Chapter of the Construction Chemical Knowledge Leadership Initiative (CC KLI) facilitated knowledge exchange and collaboration among industry experts to advance construction practices.

The discussions emphasised the transformative impact of smart construction technologies on the speed and durability of construction projects. Speakers underscored the importance of meticulous planning and the adoption of modern construction technologies. Key topics included the use of ultra-high-performance concrete (UHPC) and high-performance concrete (HPC) in infrastructure projects.

The Keynote Speaker, Dr. Debasish Bandopadhyay, discussed corrosion in concrete, showing that even high-quality concrete can be vulnerable without proper maintenance.

This was followed by a panel discussion. Col. Mahesh Narayan shared insights from large-scale projects like IIM Shillong and railway electrification. Mr. Tarun Dey emphasised that effective waterproofing is crucial for structural durability, relying on proper implementation and oversight. Dr. Syed Shahid highlighted the importance of advanced monitoring systems for maintaining structural integrity. Dr. Dipesh Majumdar examined how rapid construction may lead to early deterioration, contrasting with techniques from Japan and Korea. Mr. Krishnendu Ghosh stressed the importance of project planning, cash flow management, and minimising design changes.

The panel noted that logistical challenges, such as material transport to remote sites, can delay projects. They suggested using basic technology for on-site monitoring, as advanced tools like AI and robotics may not be feasible in all settings. They also discussed new digital platforms for improving project management and communication, especially given reduced skilled labour.

The panel concluded by underlining that waterproofing is vital for protecting structures, with its success dependent on proper application and skilled supervision. Overall, meticulous planning, effective technology use, and rigorous quality control are essential for overcoming construction challenges and ensuring structural longevity.
