According to Sub-Section 3.1 (page 13), the inner structural

embankment material shall be obtained from excavated materials, and

the CBR value when compacted to 95% MDD shall be more than 10%

(Table 2140.1). As per our experience, it is difficult to attain this CBR

requirement when just using the excavated materials. Will the

Employer be amenable to the importation of suitable embankment

From the designer‟s point of view, the excavated materials of the

type of coralline limestone could possibly achieve the subgrade

CBR value of not less than 10 % when compacted to 95 % of

MDD. However, in fact the pavement thickness has been designed

based on subgrade CBR value of 7 % on safe side. Only if the

Please confirm that Contractor is allowed to issue Performance Security

from a bank in Japan. If yes, Bidder would like to issue the

performance bond in the single currency of Japanese Yen, instead of

multi-currency bests, since it believes that it may be difficult, from

practical view point, for Japanese banks to issue the guarantee in 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)

credit (from which part of the payments to the Contractor is

being made) is suspended, the amount shown on any statement

submitted by the Contractor within 14 days after such statement

is submitted,…

Regarding the condition after “at a time when”, does it means that if the

Bank‟s loan or credit is suspended, then the payment will be received

This is exactly what is stated in the FIDIC GC, which should not be

questioned.

Remember in the past, Banks‟ loan was suspended or nulled due to

force majeure.

Alternative Bids for STP

Sludge thickener

It appears that there is no mechanical sludge dewatering but only drying

beds after the gravity thickener. Can we offer an alternative design such

as a combination of gravity belt thickener with belt filter press which

uses up less space and is much more efficient in drying/dewatering the

thickened sludge?

No, there is no mechanical sludge dewatering, but only drying beds.

Should the Contractor consider the alternative design applicable, he

can later propose Value Engineering.

Please provide clarification on the following:

a. PLC automation is not found in the BOQ but is included in the

specifications for the STP. We propose that this be inserted into

the BOQ for the STP.

b. There is no odor control unit for the STP?

c. Quantities from the P&ID, BOQ and Drawings are not consistent.

What will be our reference for the costing?

d. Do we need to include the cost of “future equipment”?

e. SC104A in drawing no. U3-3350- 03 is installed while in P&ID

drawing no. U3-3350-01 it is indicated “for future” - what will

prevail?

f. There is no ventilation provided for the STP (both in drawing and

BOQ ).

g. Schedule of SS304 pipes not specified.

h. Minimal IP rating for motors not stated - are we supposed to make

the assumptions?

i. Screen removal system (for human waste processing) - the

specifications are not very detailed. It appears that both the 70mm

coarse screen and 5mm fine screen are in the same drum. Is it

correct?

j. Fine screen A – appears to be just a bar rack without mechanism,

i.e. manual screen. Is this correct?

a. No. PLC shall be, as stipulated in the specification, included in

the instrumentation panel.

b. There is no odor control unit provided for the STP.

c. Quantities from the P&ID, BOQ and Drawings are consistent.

d. No, there is no odor control unit for the STP.

k. Automatic traveling belt screen – The specs are little confusing.

Usually belt screen is made of filtering elements moving by chain

but he bid specs seem to indicate rake. Is this a multi-rake chain

screen or a single rake vertical bar screen?

l. Clarifier bridge – based on drawings, it seems to be a diametrical

bridge not radial. Is this correct?

m. Treated water screen – This seems to be a simple wedge wire type

grid. Is this correct?


Section 3210,

Clause 5.1

Power Transformer

We refer Section 3210, Clause 5.1 2000kVA Transformer,

13.2kW/4.16 kV. The specification & drawing shows that the

connection of transformer is Delta/Delta, however vector group symbol

requires Dyn11. We understand that Dyn11 is normally used when the

transformer connection is Delta/Wye connection. This means that there

is a contradictory between the connection and vector group symbol

specification requirement. Please clarify.

In relation to connection of transformer shown in the specification

& Drawing, the Delta/Delta shall be amended to be Wye/Delta

based on primary commercial power from BOHECO 1.

Vector group symbol shall be Yd11.

for topsoil is approximate only, and to be measured by volume

(m2). Quantity for topsoil removal and storage is assumed to be the

sum of 5,000 m³ (C1-2120) and 20,000 m³ (C2-2120), or 25,000 m2

in total. Quantity for delivery of imported humus soil for the later

use of topsoiling is assumed to be 5,000 m2 (C2-2140). Therefore,

total volume for topsoil to be excavated or imported is assumed to

be, say 30,000 m2. Meanwhile, quantity for topsoiling is assumed

to be the sum of 1,405 m2 (C1-2510) and 27,000 m

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

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

TSA certificate (EDS) -

Multi-view type X-ray

The required EDS equipment L3 MVT-HR listed in the specification

7400 clause 5.1 is NOT included in the TSA list as EDS but Advance

Technology (x-ray transmission) or Non-CT technology.

In the TSA list, it is composed of two types of x-ray technologies:

1. Advance Technology (x-ray transmission) or Non-CT technology.

2. CT Technology

Explosive Detection System or EDS is based on CT Technology. So, in

the TSA list, both MVT-HR and other EDS x-ray machine model such

as HS 10080 EDX-2 is in the TSA list under Non-Computed

Tomography (Non-CT) Transmission X-ray Devices but not in the

EDS table (see page 6 of TSA list). We therefore consider that TSA

certificate which was required in specification 7400 clause 5.1 means

“Advance Technology (x-ray transmission) or Non-CT technology”.

Yes, MVT-HR is TSA certified advanced technology (X-ray

transmission, non-CT).

The equipment is recommended by IATA for Level-1 and Level-2

(residual image reprocessing) for Inline HBS (Hold Baggage

Screening).

Detector (ETD) are working on a 230 VAC power supply.

However, EDS x-ray machines are working on 3 phase, 400 VAC

used at all airports here in the Philippines. 615mm x 455mm is the

maximum baggage size that aviation authority and airlines permits as

hand carried items that will fit in the aircraft overhead cabin.

In this regard, we request that this particular provision in the

ground communication will be able to continue by Transceivers

installed at VFR room which are backed up independent Backup DC

Power Supply. Is it necessary to prepare the DC power supply as 3rd

redundant backup power supply?

The controller needs to continuously operate the radio

communication even though the disaster occurs. If the power cable

between VFR room and Equipment room is physically damaged

with shutdown, the power distribution should be automatically

transferred to DC power supply system at VFR room. Therefore the

DC power supply system should be provided at VFR room.

Company” (the JV) to participate this bid as a “Bidder”. If we could be

selected as a “Contractor”, the JV will obtain a special PCAB License

under the name of JV for this project. Likewise, the JV will apply for

TAX registration to BIR subject to Philippines Income Tax Law.

On the other hand, our corporation and “A Japanese Company” don't

have any Branch/PE in Philippines now. Considering the tax

exemption of this ODA related Project, is our understanding correct

that it's not required to apply for any tax registration under the name of

our corporation's Philippines Branch and under the name of “A

Japanese Company's Philippines Branch” by each?

Sincerely thanks for your kind confirmation and instruction.

The Bidder‟s understanding may be correct, however, the winning

Bidder must make sure by its own with tax office that the JV can be

duly paid VAT and jointly make tax return with such proposed

arrangement.
