Temporary Structures in Indian Construction: Why We Get It Wrong

Formwork failures, prop collapses, shoring incidents — many of India's construction accidents trace back to inadequate temporary structure design.

The Problem

In Indian construction culture, temporary structures are treated as low-priority. The reasoning: "It's only temporary — it doesn't need to be designed properly." This is wrong, and it is dangerous.

What Temporary Actually Means

The word describes the duration of use, not the engineering rigor required. A falsework system carrying wet concrete is under full design load.

A temporary structure must:

  • Carry the full dead load of wet concrete (24–25 kN/m³)
  • Handle construction live loads from workers and equipment
  • Account for dynamic loads during concrete placement
  • Have enough stiffness to prevent unacceptable deflection

Where the Gaps Are

No design document — many falsework installations are erected by labourers based on habit, with no engineering drawing.

Inadequate foundation design — soil conditions are assumed, not measured. Props settle unevenly.

Lateral stability ignored — vertical props need bracing. The typical site solution of whatever pipes are available is not reliable.

Premature striking — decisions based on "7 days is enough" rather than cube test results.

What Engineers on Site Can Do

  1. Document your temporary structure design, even roughly
  2. Refuse to pour if the prop layout deviates significantly from design
  3. Keep strike records tied to cube strength, not just elapsed time
  4. Raise concerns in writing — email is evidence, verbal instruction is not
