Stop Nigeria's Building Collapse Epidemic

Nigeria has experienced more than 1,000 building collapses in the past decade. The causes are consistent: use of sub-standard materials, non-compliance with approved plans, absence of stage-by-stage inspections during construction, and no occupancy certification before buildings are used. Lagos LASBCA and equivalent agencies in other states exist on paper but lack the capacity to inspect the volume of construction activity in their jurisdictions. Your challenge is to design a building inspection and compliance system that dramatically increases the probability that a building in Lagos or Abuja is inspected at the critical construction stages (foundation, columns, roofing slab). The system must work within the existing legal framework, not require a doubling of inspection staff, use technology to extend inspector reach, and create a public accountability mechanism. Submit a system design document (max 12 pages) including: how inspection scheduling is triggered, the technology for remote and in-person inspection recording, how material quality is verified, the public accountability mechanism, how developer compliance incentives work, and a plan to cover 10,000 active construction sites within 24 months. Judging criteria: 35% inspector reach extension technology, 30% public accountability design, 20% material verification approach, 15% developer incentive structure.
