Please confirm that Contractor is allowed to issue Performance Security
from a bank in Japan. If yes, Bidder would like to issue the

local currency.
Bidder‟s attention is called to GC 4.2 where it is stated that “the
Contractor shall obtain a Performance Security in the currency(ies)

camp batching plants, equipment and loading yard will be located in an
area of approx. 10ha at the North end of the site adjacent to the junction
of the new access road and the existing National Highway.” Whilst
this will be suitable for most of our construction requirements, we
would like to propose siting our main offices near to (or combined
with) the area identified for the Employer / Engineer‟s Offices and
Laboratory. The triangular area between the new Access Road and the
Boundary Fence enclosing the Buildings and Airfield would be our
preferred location. Please confirm if this may be possible as identified
as being outside of Airport Boundary as currently shown?
As shown in the drawing (for status of land acquisition) issued in

occupied by the DOTC‟s satellite office for the Project. The
property is rectangular of approximately 1 ha, where the Contractor
may partially occupy and erect his main office behind the satellite
office. Alternatively, the Contractor can propose to squeeze his
main office in the same compound of the Employer/Engineer‟s
office and laboratory shown in the Attachment-B (1/2) of

TAX registration to BIR subject to Philippines Income Tax Law.
On the other hand, our corporation and “A Japanese Company” don't

exemption of this ODA related Project, is our understanding correct
