A 1,000-tonne tunnel boring machine imported from Thailand is being assembled in Indore for the metro’s first underground corridor between the Airport and Kalani Nagar. Officials expect assembly to take about a month before shifting the machine near the Airport. The machine can excavate nearly 20 metres a day and install precast concrete segments for tunnel lining.
The project will build two parallel tunnels, including an underground station near the Airport. Around 12 km of the metro network is planned underground, with officials estimating four to five years for completion. Most components arrived in 11 trailers. Actual progress may depend on ground conditions, logistics and approvals.
The project marks a major construction step, but early estimates should be treated cautiously. Tunnelling speed and completion time can change because of local ground conditions and unforeseen delays. Public assessments also need clearer information on costs, environmental checks and disruption to nearby communities. Strong promotional claims or sweeping criticism would both be premature while these details remain unavailable.
