5 17 2.11.2

20.4 Volts dc is indicated as fully discharged battery voltage, but this is incorrect. Batteries are 12VDC, with two in series to create 24

VDC.

20.4VDCが完全に放電されたバッテリー電圧として表示されて

いるが、これは正しくない。バッテリーは12VDCで、２つを

直列につないで24VDCを作り出している。 Specification (dated July 2020) does not reference 20.4 Volts dc.

60 Hz is indicated as normal building power supply, but is this the existing power plant in Yokosuka base; not 50Hz?

建物の通常電源として60Hzが示されているが、これは横須賀

基地の既存の電源ですか？50Hzではありませんか？ 60 Hz power is available for this building.

7 20 2.12.5.2 d

Mass Notification LOC: Naval facilities only requires one LOC.

Should this paragraph be omitted to avoid confusion and possibly unnecessary cost?

非常放送のLOC:海軍の基地では１つだけのLOCが要求される。

混乱と不必要なコストをさけるために、このパラグラフを削

除すべきではないか？

Specification (dated July 2020) does not include a paragraph 2.12.5.2_d. In addition, Drawing Sheets FA101 and FA603 indicate only one LOC provided for the facility.

8 22 2.14

Amplifier spare capacity: It is stated calculation with one tap setting higher than the anticipated tap setting, but this would be excessive spare capacity, even with modification of USFA requirement of 50% spare at maximum wattage.

アンプの容量：仕様書は、「予想される設定の１つ上の設定

で計算」と述べられているが、これはUSFAの最大ワット数の

50％のスペア要求を考えても、過剰だろう。

されている。1ヘルツだけは現実的ではない。

Paragraph 2.16.2 in specification (dated July 2020) indicates a strobe flash rate of 1‐2 flashes per second.

Upper left note indicates “All devices, …in the maintenance area 202 must have a black or dark colored factory finish.” There is a red or a white device. It will violate the UL listing to paint device after the factory finish.

Drawing G‐

The contract period seems short. It takes time until the application for the asbestos/lead abatement work is approved. Since a wide range of excavation is involved, it takes time to coordinate with other related parties. At least 510 days are necessary. The contract period should be 600 calendar days with a 20% increase.

510日は実質かかります。カレンダーデイは20％増の600日と

するべきです。

The contract period remains unchanged due to mission requirements.

Bid Item 0001, Base Bid, reflects a completion period of 420 calendar days based on Fast Track or accelerated completion of Phase 1.

Bid Item 0002, Alternate Bid, reflects a completion period of 510 calendar days based on the assessment of the construction requirements.

14 Drawing S‐603

The intention of “OUTLINE OF RUBBLE CONCRETE” is not clear. It should specify how it is related to the geological survey.

OUTLINE OF RUBBLE CONCRETEの考え方がはっきりしません

地耐力調査とどう関係しているのか示すべきです。 See Drawings S‐602 and SA‐101 showing soil boring information for foundation level and depth.

Drawing ET‐

Has the TELECOM work been coordinated with BCO? Since it is usually not coordinated in advance, it has always been causing problems.

TELECOM工事は基地のBCOと調整済みでしょうか？

何時も事前調整してなく最大のトラブルの原因です。

Coordination with BCO has been made for the regular system.

However, the Telecom System for this project will be handled by NAVAIR (Using Agency).

Drawing FX‐

The roof slope is 19.3 degrees. I think it does not meet the NFPA specifications.

Measures are needed. Please refer to the attached file.

屋根勾配が19.3度です。NFPAの仕様に合わないと考えます。

対策が必要です。添付ファイルを見てください。 The facility is not designated as a storage occupancy so the criteria of NFPA 13, Chapter 20 is not applicable.

Drawing A‐

A new steel pillar is installed on the structure of the existing office.

Should it not be a problem in earthquake resistance?

既設OFFICEの構造体に新設の鉄骨柱が取り付いているが耐震

的に問題ないか？

Calculations of the loads at the construction time were compared it with the new loads to be imposed, establishing the limitations of the existing load carrying capacity. Therefore, loads actuating in an eventual earthquake shall not exceed the original structural design capacity.

18 Drawing C‐001

It is necessary to consider encountered contaminated soil due to excavation work.

掘削作業による汚染土の検討が必要である

See note 12 on Dwg. C‐001.

We would like to request the bid due date be extended by two weeks. The reason is that the manufacturer was closed due to the holiday, and we need more time to quote.

入札期日を2週間延長して頂きたい。理由は、お盆休みにより

メーカーが休業していたためであり、見積もりにさらに時間

が必要です。

Refer to Amendment 0001. The date for receipt of bids is extended from 03 September 2020 to 14 September 2020 at 10:00 AM local time as target award is on or about 30 September 2020.

On page 27, it says that the amount of the bid guarantee shall be 20 percent of the bid price or ¥300,000,000 Japanese Yen whichever is less. In this case, should the bid guarantee be 20 percent of the total amount of Bid Item No. 1 Base Bid and Bid Item No. 2 Alternate Bid or either one of them whichever is higher?

Bid guarantee shall be based on whichever bid amount is higher (Bid Item No. 1 Base Bid or Bid Item No. 2 Alternate Bid).

21 11 RFP B.1 The site visit was conducted on 17th Aug., however the bid due date is 3rd Sep. and there is not enough time for us to prepare for the bidding. Is it possible for the Government to extend the due date by 60 calender days? See response to Question 19.

G‐004 The 3rd item under SEQUENCE‐1 in the PHASE‐1 on G‐004 indicates to refer to SHT G‐006 for confirming the temporary facility, "INTERIOR ENCLSURES". However, the G006 is not included in the provided drawings, and we cannot confirm. Please provide the Sheet G006. We think that it is difficult to protect the ELECTRICAL EQUIPMENT by creating some enclosure in portion of the existing Bldg. A32.

This is a typo, it should say G‐005. There is no Dwg sheet G‐006.

Interior enclosures refers to the temporary barricades and protection of existing facilities and equipment remaining on site, to be provided by the contractor as part of his construction site plan in accordance with the contract specifications.

1.4 a It is very difficult for KTR to perform works in occupied building with Government regular operation. For example, there will be a large noise and vibration during the demolition works for the existing concrete floor and structural steel flame works, and we believe that such works will interfere with the Government operation. We recommend the afflicted area to be unoccupied during the construction. Building occupants are aware of this construction effort and

Government operations will continue to the extent possible.
