The fatal accidents happen
everywhere. These accidents not only influence the workers and projects but
also have direct effect on money and time. It normally takes much money to
compensate the loss of workers and to repair the damages of the project and
many other expenses. Besides, it consumes much time during accident investigation,
designing, repairing and sometime for legal questions.
Some people think that accidents
are unavoidable. Hoang Don Dung made a study to improve and analyze every
aspect of the problem in detail and propose recommendation. The objectives of
his research were to:
1. analyze the reasons of the recent
construction accidents in Vietnam which are related with the quality of
temporary structure.
2. apply the regulation of
Vietnam government and FIDIC contract to study these accidents.
3. give out some recommendations to
improve the safety and quality of temporary support structure in construction
process.
Conclusion
Studying
occupational accidents happened in the past. We can recognize that there were
two kinds of them: predictable or unpredictable. But the damages of these
accidents were taken by human. A predictable occupational accident means
avoidable if we do the right work. Most accidents of temporary construction
structure in the past are predictable and avoidable but they have happened
because the behavior of construction employees is subjective.
Many people at
site often think that every temporary structure is just serving for executing a
super-structure, it is not worth for long time. The executing weight loading on
temporary structure is short-term load, too. The owners or customers won’t
check it closely and in detail like other parts of project. In fact, some kinds
of loading capacity may load on super-structure but not on temporary structure
such as loads defined by probability, loads following seasons, earthquake, etc.
This makes ideas of disregarding the temporary structure systems.
In many
projects, temporary structures have not been considered as superstructure in
processes of designing and executing.
That means before
implementing the temporary structure at site, it must be designed in detail
attending the applied standard and codes. The design drawings and specification
must be verified and accepted carefully by the Engineer/Supervisor as defined
by Fidic terms or Vietnam Decree 209 to the superstructure.
Before implementing
the temporary structure at site, its materials must be tested based on the
applied standard and codes. Contractor may use old material but loading
capacity must be ensured. Besides, using materials for the temporary structure
must obey specification.
Contractor’s
technical staff and owner’s supervisor must supervise and accept temporary
structures carefully to achieve technical requirements defined by approved
design and specification.
Recommendation
To solve the
problems, the support of authority is indispensable. Government policies should
have to regulate besides the regulations that were defined in Decree 209 (or
the Fidic conditions of contract if applied) as follows:
a. Every temporary
structure must be behaved as superstructure in designing and executing process.
b. Contractor’s
employees have to be trained appropriately. They have to have proper profession
certificates.
Abstract
Years by years, the persons who
do their routine work at construction site still try to devote themselves to
their jobs. Now and then there is information of a construction accident
happened somewhere, they hear information and feel sorry for their coworkers.
Then they can forget it at once because they think simply that accident was not
their case; it does not relate to them.
Is that true? Don’t they relate
completely and absolutely to any occupational accident though it happens out of
their construction site? The answer is no because each of them is playing a
roll in construction sector. Each person has his obligation of occupation.
Somehow, by his opinions or activities he can help either to prevent accidents
or reduce damage. He may not keep it for himself. Therefore those opinions must
be written down.
This report writes about
occupational accidents happened in Vietnam construction site in several recent
years. The accidents happened by poor-quality and un-safety of the different
temporary structure systems at the different site but basically the causation
is human. They did not put all their consideration to the temporary structure
because it’s non-permanent. In fact, they did design, manage, execute and check
the temporary structure carelessly.
The author hopes that this report
will give a more opinion to persons who do their routine work at construction
site related to temporary structure systems. They will play very well their
rolls at site as defined by government regulations and/or terms of Fidic
contract.
