Some newly awarded failure analysis and accident investigation projects:

  • Failure analysis and accident investigation on explosion of electric storage water heater by Consumer Safety Department of Singapore Government - Spring Singapore/Enterprise Singapore

  • Failure analysis investigation on damage items at and/or recovered from incident sites (two year contract + one year option) by Singapore Civil Defence Force (SCDF)

  • Failure analysis on fractured manhole framesets from Public Utilities Board (PUB)


  • Failures and accidents often occur on products, facilities, infrastructures, production line and work sites in various industrial sectors, not only resulting in huge economic loss but also fatalities in some cases. It’s critical and imperative to perform failure analysis and fornsic investigation to determine the failure cause(s), failure mechanism(s) and provide counter measures to prevent similar failure(s) recurrence in future. Effective failure analysis (FA) and accident investigation can not only enhance reliability and safety of products and infrastructures, but also improve product quality and reduce operational cost and down time of facilities so that improve productivity.

    Objectives of failure analysis & accident investigation

      Effective failure analysis (FA) and accident investigation will:

    • Determine root cause(s) of failures/accidents/incidents.
    • Find out mechanism(s) of failures, incidents and accidents.
    • Recommend counter measures and solutions to prevent recurrence of failures and accidents.
    • Support litigation/court hearing on litigation/liabilities related to failures and accidents

    Recent Court Cases

    A mobile crane toppled when lifting an 40 feet container, resulting in damages amount to several hundred of thousands dollars. UTC was engaged to investigate the accident causes and as expert witness in legal litigation. According to the court record, the Judge accepted our conclusion that the crane toppled was due to defective/malfunctional AML system.

    A heavy gate toppled during installation and caused a worker death. UTC was engaged by MOM for accident investigation and as expert witness in this court case. According to Straits Times and Channel NewsAsia's reports, the court ruled that the contractor was fined S$280,000 for fatal gate toppling. The contractor filed appeal, but lost the appeal and punishment was increased from S$280,000 to S$330,000 for fatal gate toppling, reported by Straits Times. UTC had successfully determined the root causes of the accident and testified in the court hearing by providing solid evidences with scientific methodolody.

    One crane collapsed in a construction site, which severely damaged the nearby plant facilities and workshop during lifting operation. China Taiping Insurance engaged UTC to investigate the accident and as expert witness in legal suit. We successfully determined the root causes of the accident. Shortly after receiving our report, the case was settled favourably before court hearing.
