Pre-feasibility study started. But under construction expressway may create problem.

It is old news. Has it not already been completed?

In Chittagong - the route has to be planned carefully because of several low lying hills (~200-500 ft. high) which may require a combination of pier-supported and tunnel boring situation.

This is quite unlike Dhaka where Line 6 was totally pier supported (above ground). However for Lines 1 and 5 there will be a combination of 'above-ground' and 'cut-n-cover' construction methods adopted. If soil-liquefaction and integrity is NOT an issue (or cost of remediation thereof), then they MAY bore under hills using the Tunnel Boring Machine (TBM) method. BUT TBM is the most expensive because of,

a) how expensive the borer machines themselves are, and
b) the massive shuttering costs at the entrance and egress points of the tunnels.

Likewise, it is the last resort of all the available options - like in the Karnaphuli tunnel under the mouth of the Karnaphuli, as is currently ongoing. It is the first TBM project in Bangladesh.

Good news. BD needs to consider metro in other big cities.

Infact surprised Chittagong did not have the metro first

The population in Chittagong is a distant (distant!) second to Dhaka and hence this is not an imminent and emergent need. Dhaka has fifteen million people in the metropolitan area proper. Chittagong at present may have around five million at best and that includes the population of all the city districts (thanas) and subdistricts (upazilas) in the Metropolitan Area of Chittagong.

But there are huge export zones around Chittagong and population is expected to increase rapidly to at least ten million in the next ten years as urbanization increases and matures in that area. Better to do it now (and less expensive) before uncontrolled urbanization presents issues later for rights-of-way development.
