Smart City mission is an urban renewal and retrofitting mission to develop 100 cities across the country making them citizen friendly and sustainable. The pace of implementation of project has been considerably low with the demands of a fast-growing economy, a mere 31 projects worth of Rs 1,882 crore are under implementation so far, while 11 projects worth Rs 443 crore still wait for the completion of the tender process. The original plan was that the mission will cover 100 cities and its duration will be five years (FY2015-16 to FY2019-20).
Smart cities are concerned about three broad categories – smart living, smart safety, and smart sustainability. Building such an infrastructure, there are many design touchpoints. Construction and project teams have to collaborate closely as well. The volume of asset information is heavy in any Smart City project and all these teams have to work together to ensure that the information exchange happens seamlessly.
A smart city project depends highly on integration to develop an intelligently integrated infrastructure for transport, communication, energy consumption at the building, as well as on the city scale. In such mega projects, the buildings remain permanently integrated with these other bases. Putting this jigsaw together is a complex task to manage. Thus, converting a design masterpiece into physical structures requires great precision. BIM’s highly detailed, precise and constructible 3D structural models help in project visualization from conception to completion. BIM models can also easily test building constructability in advance and ensure that errors, rework and any wastage is minimized.
It is not just at the stage of design and construction that technologies like BIM and Internet of Things (IoT) have a role to play, stressing their utility in the long-term maintenance of structures.
These technologies help reducing project duration by 50% and the cost of field layout by 50%, besides improving accuracy by 80%. Data storage on the cloud is another enabler, as it allows the different stakeholders in the construction process to work in sync, reducing errors and ensuring better predictability of costing and timelines.
