BMC Integrates 3D City Model with Civic Systems for Enhanced Oversight

The Brihanmumbai Municipal Corporation (BMC) has initiated the process of integrating its 3D digital model of the city with multiple civic systems. This step is aimed at improving how urban data is used for planning, approvals, and revenue monitoring. The integration currently covers departments such as building proposals, property tax, and estates, with more departments expected to be added in phases.

The 3D model, often referred to as a digital twin, provides a detailed representation of Mumbai. It maps buildings, roads, bridges, flyovers, underpasses, open spaces, water bodies, and even slum clusters. The platform also enables a 360-degree street-level view, helping officials examine specific locations closely without physical site visits.

With this integration, officials can directly compare approved building plans with on-ground structures. This is expected to help identify unauthorised constructions, encroachments, and deviations from sanctioned layouts more efficiently. It also allows departments to verify details such as building height, floor configurations, and road access before granting approvals or taking action.

Another key objective is to improve revenue collection. By linking the digital model with property tax records and estate data, the civic body can identify mismatches in property size, usage, and classification. This is expected to reduce leakages and ensure that taxes and development charges are assessed more accurately.

Officials indicated that the system will be particularly useful in dense and older parts of the city, where buildings are closely packed and manual inspections are difficult. Remote monitoring through the 3D model can help track structural changes and redevelopment activity in such areas more effectively.

The platform also supports better coordination between departments. Data layers related to underground utilities, infrastructure networks, and existing developments can be accessed together, allowing more informed decision-making while planning new projects or granting permissions. This is expected to reduce delays caused by fragmented data across departments.

The integration also has implications for infrastructure planning and disaster management. Authorities can use the model to run simulations, assess the impact of proposed developments, and plan upgrades with a clearer understanding of existing conditions on the ground.

This move follows recent steps taken by the civic body to digitise approval processes. In the past few weeks, the administration has been working on introducing AI-based systems to streamline real estate approvals and reduce manual checks. The 3D model integration is seen as an extension of these efforts to improve transparency and efficiency.

Experts believe that such systems can address long-standing issues in the city’s development process, where differences between approved plans and actual construction have often led to disputes and revenue gaps. A more accurate and visual system of verification is expected to improve accountability for both developers and authorities.
