Emerging Technologies in Civil Engineering The Construction Industry has undergone revolutionizing changes in the last decade by embracing technological advancements. New-age construction methods have become highly efficient to ensure faster delivery time and cost-effectiveness. From construction drawings within blueprints during the 19th century to its gradual shift to whiteprint and now 2D and 3D CAD drawings, the industry has witnessed a digital transformation in its methods and practices. The present- day Building Information Modelling (BIM), 4D Scheduling, and 5D cost modelling mark the beginning of a new era of construction technology. The 4D project management software simulation of construction progress tracks and validates the process including temporary works, traffic management, construction work tasks, as well as coordinates supplies and progress delivery to optimize project plans much ahead of time. Application of Robotics has also made a disparity in the industry and in making the lives of the construction industry workers safer and effortless. With the help of Artificial Intelligence, Automated Rovers can now provide Jobsite status information, monitor sites autonomously and feed data back to the predictive analytics systems. The industry has also adopted prefabrication technology, available at different budgets for assured quality of construction and speedy completion. Formworks have evolved from conventional timber to MIVAN and Tunnel formworks, which assure high-quality control measures and save time significantly. Green and innovative materials are being preferred as these are recyclable, reusable, non-toxic, and they engender little pollution. The practice of using air cleaning bricks on the outside of the building is prevalent as it funnels air into an internal cyclone filtration section separating heavy elements and drops them down into a hopper at the base of the wall, pulling clean air into the building.

Building-integrated photovoltaic glazing helps the building generate its electricity by turning the whole building envelope into a solar panel. Kinetic footfall in road pavements and footpaths is a sustainable energy source used for generating electricity. However, despite these innovations, project execution faces major challenges due to slow adoption of the new technologies, non-availability of skilled laborer’s and material resources, improper risk management techniques, improper planning, changes in design, coordination issues in site management, and lack of budgetary control. Therefore, implementation of latest technology has an additional cost factor involved as it is imperative to develop training programs for unskilled laborer’s, outsource labor-hire requirements, and provide safe and healthy work environment to address the manpower scarcity issues. By controlling procurement, carrying cost can reduce total project cost and fast track project completion. Inventory categorization, resource levelling and smoothening assure material usage at an optimum refined level so that the storage cost can be eliminated. Enterprise Resource Planning (ERP) with analytics using data from various construction processes allows manufacturers to proactively manage operations and prevent disruptions and delays. Even though the industry has witnessed many disruptive changes over the years, it has been relatively hesitant to implement these practices and technologies aggressively. Although these are established methodologies by now, the industry still trudges along with the traditional methods. At the pace technology is advancing and being adopted across various segments of our lives, the construction industry to needs to be high tech-driven to add value to the customer and operate with profitability.
