BIM adoption in smart cities at construction world
This July 2015, Construction world released an article focusing on Challenges faced by the Indian Government in implementing Smart Cities project. As the Indian government has planned to launch smart solutions to meet the need of growing urbanization and have approved 100 smart cities project in India.
Many industry experts contributed to different solutions to the challenges highlighted within the article. Like,
Mr. Pratap Padode says, ¨The Smart Cities mission and AMRUT are likely to infuse a total of Rs 400,000 crore, once integrated with other missions like Digital India, Swachh Bharat, Housing for All, etc.¨
Mr. Kanwaljeet Singh, Business Development, Energy and Smart Cities, Schneider Electric India say’s “At present, only Lavasa near Pune can be classified as a smart city. Other cities (such as Mumbai and Delhi) are still in the process of upgrading their systems and could qualify as smart in the future.¨
¨We have been talking to these cities about the best way to do this, following which they will come up with their procurement procedures,¨ says Aamer Azeemi, Managing Director, Cisco, adding that the company is in discussion with many cities. ¨We have done the complete smart city planning for four cities in the Delhi Mumbai Industrial Corridor,¨ he shares.
Similarly under the “Utility and Solutions” section where there are two components to any smart city: Physical infrastructure and software. Every city, from ancient times to now, has required roads, water, power, parks, security, transportation, shopping, food production, and services of different types for its citizens. What has changed is that all these facilities can now be designed using analysis of data . Therefore, you get smarter roads where traffic lights are coordinated with the amount of traffic and smarter water by measuring the amount of water being consumed and then planning how much to buy, how much to clean and purify, and how much to store and distribute. While smarter power and the fine granular measurement can improve load factors and reduce electricity cost, smarter grids for electricity distribution improve the resiliency of power networks. Additionally, smarter transportation, agriculture and services can be possible by backing every decision with data collection and analytics.
This considered, the benefits building information modelling (BIM) offers at various stage are proven. “It can play a significant role to make smart cities a success”. She highlights some goals for BIM adoption or implementation in smart cities:
- At the design stage: Visualisation of the project leads to reduction in coordination time; reduction in time by design changes; accuracy in data used for construction as BIM lets us build virtually before building physically.
- At construction stage: Reduction in rework at site owing to clash detection and resolution; accuracy of Bill of Quantities (BOQ) and consequently material procurement; delay monitoring through 4D construction simulation; availability of an as-built model for facility management.
- At maintenance stage: Integration of design data with maintenance data; impact of any updates or renovations can be assessed against the data available in the BIM model. reference the article THE SMART CITIES CHALLENGE.
