The Greater Chennai Corporation (GCC) will upgrade civic infrastructure across about 90 km in three industrial estates in the city, covering Ambattur, Guindy and Vyasarpadi. The project is divided roughly into 50 km in the Ambattur Industrial Estate, 20 km in Guindy and 20 km in the Vyasarpadi Cooperative Industrial Estate, the GCC Bus Route Roads department said. As a first step, GCC will float tenders to appoint a consultant to prepare a detailed project report. The scheme covers roads, stormwater drains, footpaths and streetlights. The appointed consultant will conduct a detailed survey of the three estates to assess infrastructure requirements and to prepare estimates and a phased implementation plan. The survey scope will include carriageways, footpaths, stormwater drains, streetlighting, solid waste management and other essential services, with priorities set on connectivity and drainage resilience. Based on the survey findings, the consultant will draft technical specifications, cost estimates and a schedule for phased execution to enable the GCC to invite construction tenders. The upgrade in Ambattur and Guindy follows a memorandum of understanding signed earlier this year between the GCC and the Tamil Nadu Small Industries Development Corporation, under which the civic body assumed maintenance responsibility for roads, streetlights, stormwater drains and solid waste management in those two estates for 30 years. Vyasarpadi’s inclusion responds to long standing requests from workers and industrial stakeholders in the cooperative estate, which falls in the Perambur assembly constituency represented by Chief Minister C Joseph Vijay. GCC officials said bringing the three estates under a single project will streamline maintenance and improve service delivery for industrial units that depend on reliable civic infrastructure. The corporation will phase works to limit disruption to industrial activity and to allow timely handover of completed stretches. Procurement for consultants and contractors will follow the statutory tendering process and implementation will be monitored by the civic administration.
