AKEN — A brand of A K Engineering

Engineering knowledge portal

Engineering lessons. Safer structures. Stronger tomorrow.

Real-world structural failures, construction accidents, engineering observations and preventive measures — to understand why structural stability, fabrication quality, safe erection and continuous inspection matter.

Every incident here has been traced to a working source. Casualty figures that conflict between outlets are published as a range, not tidied into one number, and engineering mechanisms are presented as possibilities rather than causes.

Steel erection & temporary stability13 Oct 2026

Warehouse shed collapse during erection, Mankivali

Mankivali village, Khalapur, Raigad, Maharashtra

An under-construction warehouse shed collapsed while it was being erected near Khalapur, Raigad. One worker was killed and between 15 and 25 were injured depending on the source.

One worker was killed.

Warehouse collapse under investigation, Taratala

Taratala, Kolkata, West Bengal

An under-construction warehouse collapsed at Taratala, Kolkata. A police chargesheet later named seven people, with reporting referring to substandard materials, deviations from approved plans and steel beams buckling under fresh concrete.

Slab collapse on the Vikramshila Setu, Bhagalpur

Vikramshila Setu, Bhagalpur, Bihar

A 25-metre slab section of the Vikramshila Setu at Bhagalpur collapsed. No casualties were reported, and structural and safety audits were subsequently reported to be under way.

No casualties were reported.

Understanding structural failures

Fifteen mechanisms explained from first principles: how the failure works, what causes it, what the warning signs look like on a real structure, how to inspect for it, and which standards govern the design.

Our approach

How AKEN approaches structural safety

Eight stages, each with controls a client can inspect. These are the points at which a structural failure of the kind catalogued on this site is normally either prevented or allowed.

  1. 01

    Engineering review

    Before anything is cut, the approved drawings and the assumptions behind them are checked: the load cases, the structural details, and whether the drawing revision on site is the one that was designed.

    • Approved drawings and current revision
    • Design assumptions and load cases
    • Structural details and connection design
    • Buildability against the erection sequence
  2. 02

    Material verification

    Steel is verified against the specification on receipt. Mill certificates and heat numbers are what link the member in the structure to the grade that was designed for it; without that chain a substitution is undetectable afterwards.

    • Mill test certificates and heat numbers
    • Grade verification against the specification
    • Traceability from delivery to member
    • Incoming dimensional and visual inspection
  3. 03

    Fabrication quality

    Cutting, fit-up, welding, surface preparation and coating are inspected at defined points. Fit-up is checked before welding is closed out, because after that the only options are expensive.

    • Dimensional inspection at fit-up
    • Welding to a qualified procedure, with welder qualification
    • Weld inspection to the specified method
    • Surface preparation grade and coating thickness
  4. 04

    Anchoring and connection quality

    Anchors are where a structure meets its foundation, and almost all of the performance lives in preparation rather than in the product. Hole cleaning, embedment and curing are the variables that decide whether an anchor holds.

    • Substrate inspection before drilling
    • Hole diameter, depth and cleaning to the system data sheet
    • Anchor selection against the application and its approval
    • Adhesive injection, curing and torque checks
    • Testing where the specification requires it
  5. 05

    Erection and installation

    A partly erected frame is a different structure from a finished one and has to be stable at every stage. The erection sequence, the lifting plan and the temporary bracing are engineering documents, not site preference.

    • Approved erection sequence and methodology
    • Written lifting plan per pick
    • Temporary bracing designed and installed
    • Connection completion verified before crane release
    • Stability confirmed at each intermediate stage
  6. 06

    Site safety

    Fall protection, permits, exclusion zones and rescue arrangements. The controls that keep the crew alive are also the controls that keep the job legal under Indian construction safety law.

    • Risk assessment and method statement
    • Permits to work where the site is live
    • PPE and full-body harness at height
    • Exclusion zones under every lift
    • Emergency and rescue response
  7. 07

    Inspection and documentation

    Inspection is only a control if it is recorded, and a record is only a control if a non-conformance closes. Stage-wise sign-off is what stops a deviation progressing to the next stage.

    • Stage-wise inspection held points
    • QA/QC records and inspection reports
    • Non-conformance register with owners
    • Corrective action closed out and verified
  8. 08

    Maintenance and retrofitting

    Structures deteriorate, and the failure mode is usually one that was inspectable long before it was visible. Condition assessment, corrosion mapping and periodic inspection are how a structure is kept serviceable rather than replaced.

    • Structural condition assessment
    • Corrosion inspection and section loss measurement
    • Crack and deformation monitoring
    • Repair or retrofit methodology and its verification
    • Periodic re-inspection on a defined cycle

On scope: this framework describes how AKEN controls the work it carries out. It does not represent that AKEN provides engineering certification, statutory inspection, non-destructive testing, design approval or any specialist service that is not available and authorised for a specific project. Where a stage depends on a third party — an approved designer, a test house or a statutory authority — that third party is named on the project’s own documentation, not implied by this page.

Our position

Engineering responsibility. Structural safety. Long-term performance.

At AKEN, we recognise that every industrial structure carries a responsibility towards human life, operational reliability and long-term structural performance.

Structural failures are serious reminders of the importance of proper engineering, quality materials, correct installation procedures, effective supervision and continuous inspection. We take these lessons seriously.

For every project undertaken within our scope, AKEN is committed to implementing appropriate engineering reviews, material verification, fabrication quality checks, approved installation methodologies, anchoring procedures, site safety practices and documented inspections.

Our approach focuses on identifying potential risks before they become problems, following approved engineering specifications and addressing deviations through proper technical review and authorisation.

Our promise

We do not compromise on engineering responsibility, workmanship, quality control or site safety.

While no engineering or construction activity can honestly guarantee zero risk or the complete absence of defects, AKEN is committed to taking every reasonable and technically appropriate preventive measure within its scope to minimise risks and deliver work in accordance with approved project requirements.
