and Construction Superintendent with work experience of not less than 5 years each

and not less than five maintenance and instrumentation and control specialists.

(In case a Bidder submits a Bid for Lots 1 and 2 or for Lots 1 and 2 and 3 because of

the need to execute works simultaneously, it has to provide the information about the

personnel capable of performing the scope of works simultaneously at two projects,

specifically the information about availability of at least a qualified Chief Engineer and

two Construction Superintendents on the staff with work experience of not less than 5

years each, and not less than ten maintenance and instrumentation and control

specialists).

d. Availability of, at least, five concluded and successfully performed contracts for pre-

commissioning works of a similar nature, including at least 1 successfully performed

contract for each of the following types of work: pre-commissioning works on the

59

company’s Balance Sheet and Certificate of good standing.

g. Company’s annual turnover of not less than USD100,000 in 2014, 2015. (In case a

company submits a Bid for Lots 1 and 2 or for Lots 1, 2 and 3, the annual turnover

should be not less than USD200,000).

h. Elaboration and inclusion of the pre-commissioning works program and estimated cost

conforming to the Terms of Reference into the Bidding Documents.

draw up the Act to be forwarded to the Contractor for elimination of defects.

d. Calculation of the warranty period is suspended for a period of elimination of defects due

to the Contractor’s fault. The period for which the warranty period is suspended is to be

calculated from the date of signing the Act of Defects Detection and terminates on the date

of signing the Act of Completion of Remedial Works.

e. The remediation period within the warranty period is not more than 10 calendar days from

the date of notification by the service provider.
