Every major construction collapse in India prompts the same cycle: shock, investigation, compensation, then silence until the next one.
A significant number of these collapses happen not because the permanent structure was weak, but because the temporary structure holding it during construction failed.
The Problem with "Jugaad Engineering"
In Indian construction culture, temporary structures are often treated as low-priority. The reasoning: "It's only temporary — it doesn't need to be designed properly."
This is wrong, and it's dangerous.
What "Temporary" Actually Means
The word "temporary" describes the duration of use, not the engineering rigor required.
A temporary structure must:
- Carry the full dead load of wet concrete (typically 24–25 kN/m³)
- Handle construction live loads — workers, equipment, dumpers
- Account for dynamic loads during concrete placement
- Have enough stiffness to prevent unacceptable deflection
- Be designed for safe erection and dismantling
Where the Gaps Are
No design document — many falsework installations are erected by labourers based on judgment and habit, with no engineering drawing.
Inadequate foundation design — soil conditions are assumed, not measured. Props settle unevenly on soft ground.
Lateral stability ignored — vertical props carry vertical load well. But they need horizontal bracing and diagonal ties. The typical site solution of cross-bracing with whatever pipes are available doesn't provide reliable restraint.
Premature striking — the decision to remove formwork should be based on concrete cube test results showing adequate strength. In practice, it's often based on elapsed days.
What Good Practice Looks Like
- Design drawings for any non-trivial falsework system
- Propping loads checked against slab or beam capacity below
- Striking schedules tied to cube results, not just time
- Named responsible person for falsework inspection
- Inspection checklist signed off before any pour begins
What Engineers on Site Can Do
You don't need to be the decision-maker to make a difference:
- Document your design, even roughly — a sketch with load calculations beats nothing
- Refuse to pour if the prop layout deviates significantly from design
- Keep strike records — date, cube strength at time of strike, who approved it
- Raise concerns in writing — email is evidence, verbal instruction is not
The workers who erect and dismantle falsework are the most exposed. They deserve engineered protection, not improvised structure.
