A Multi-Function Metro Concept | Ý Tưởng Kết Hợp Tàu Điện Ngầm, Cao Tốc Và Nhà Ở Xã Hội

The video introduces a multi‑function metro concept that merges subway tunnels, highway corridors and social‑housing units under a single infrastructure umbrella. The presenter argues that such integrated corridors can serve as long‑lasting transport arteries while simultaneously delivering affordable apartments in Hanoi and Ho Chi Minh City, where housing shortages are acute. Key elements include a profit‑sharing model: developers sell social‑housing units at roughly VND 12‑13 million, generate a VND 12‑25 million margin, and channel that surplus into road construction, eliminating direct government outlays. A novel “rầm bản rỗng trên cọc ly tâm” foundation technique is touted as low‑cost, suitable for rural, peri‑urban and swampy sites, reducing foundation expenses to slab‑and‑wall work only. The speaker cites concrete figures—selling units for VND 25 million while costing VND 12‑13 million to build—and emphasizes that the tunnel’s lifespan could extend to five centuries, far exceeding typical 100‑year expectations. He offers the design to the state, pledging guidance for contractors to adopt the method as a “peaceful solution” for infrastructure challenges. If adopted, the model could reshape urban development by aligning transport and housing standards, cutting public capital requirements, and accelerating delivery of affordable homes. Realizing this vision, however, hinges on regulatory reforms that merge transport‑infrastructure codes with housing construction norms.
