injury or illness or disease suffered by a person employed by any other
sub-contractor.”
Revised Clause 4.6.1
“Liability in respect of death, bodily injury, illness or disease suffered by:
1) Any person employed by any insured party i.e. principal contractors,
sub-contractors, sub-sub-contractors for the purpose of execution of
insured contract or any parts thereof and
2) Any person to whom part or parts of the insured contract have been
sub-contacted including but not limited to self employed
sub-contractors.”
In essence, the original clause 4.6.1 has no cover for death/injury to
employees of contractors or sub-contractors because they should have
separate insurance cover under employee’s compensation ordinance.
However, it does not exclude the liability for “worker to worker” i.e.
sub-sub-contractors. For the revised Clause 4.6.1, it rules out the liability
for death/injury to employees of any insured party.
6. Should design life be the same as return period for design
conditions? (GI4)
Design life means the minimum duration a structure is expected to last.
The longer is the design life; the higher is the cost of a project. Therefore,
in choosing the design life for a structure, engineers should consider the
design life which generates a economical project without sacrificing the
required function.
In selection of return period of certain design conditions, winds, waves, etc.,
one should consider the consequences of exceedance. In fact, there are
normally no extreme maximum values of these design conditions and its
selection is based on the probability of exceedance which is related to
return period.
Therefore, design life may not be equal to return period of design
conditions because their selections are based on different considerations.
7. What is the difference between sureties and security? (GI5)
In construction contracts, if a contractor fails to perform the works, the
employer would suffer from severe financial loss and therefore some forms
of protection has to be established in the contract.
