Inspected by: Younten Jamtsho
Report Generated by: Nezar
Inspected on February 27, 2014
SUMMARY
C.D.F Design (BD). is located in Diganta Complex. Diganta complex consists of three
multistoried buildings and seven separate sheds covering 432000.0sqft of land. The buildings and
sheds were constructed as industrial structures. There were 9777 workers in the premises, during the
inspection.
The Factory was surveyed for electrical safety by Woosun Energy and Construction Co., Ltd.
(WEC). The purpose of the survey was to identify significant electrical safety issues and to provide
recommendations for remediation based on applicable standards specified by the Accord. The
scope of this initial electrical safety inspection was limited to the review and identification of major
electrical safety issues. The inspection did not include identification of minor deficiencies, which will
be further addressed as part of follow-up inspections.
Table below summarizes the major electrical safety issues identified during the inspection.
Recommendations have been provided to address each issue.
An implementation schedule shall be developed by the factory to remediate each of the
findings. The specific timing of improvements, including any requested extensions due to
design / installation constraints, shall be submitted to the Accord for approval.
