Gov. answer No.16 In Amend 02

After the Turbidity Protection Floating Frame is provided, vessel will not be able to berth. Is it allowed?

Yes, the vessel of Government will not berth at work area during dredging construction.

However contractor must follow the Contracting Officer’s decision if work is suspended for Government ship operation.

Gov. answer No.27 In Amend 02

Although it is indicated as "There is no maximum percentage increase or decrease specified in FAR 52.211-18" on the Gov.

answer, is there no maximum amount to increase the contract price?

There is no maximum percentage increase or decrease specified in FAR 52.211-18. As such, there is no maximum JPY increase or decrease in contract price.

The contractor shall promptly notify the Government if they expect the quantity to vary more than 15 percent above or below the estimated quantity.

According to the drawing, dredged soil shall be included YOBORI (30cm). Should we maintain the maintenance depth indicated on the drawing? It seems to become deeper if YOBORI is included.

Yes, the maintenance depth indicated on the drawing must be maintained.

Dredged soil volume on the drawing is included YOBORI (30cm).

For dredging work, is there any possibility that dredging work will be interrupted by other than related Gov. regulation.

There is a possibility that dredging work can be interrupted by Non-Government related actions….i.e. weather/natural disasters.

Currently, there is no accurate sounding measurement data existed.

Also, the size and quantity of construction area are not clear, and also it is not clear in those of transporting distance to a sediment disposal facility; treatment capacity per day; accepting agency's requirement.

After pre-survey is completed and sediment disposal facility is determined, the specification of workship and the number of ships will be considered.

Is it possible for the Gov. to modify the design including the extension of construction period?

Dredging area is clearly shown in drawing C-101.

Dredging volume is shown in drawing and spec for biding purposes, so offeror should bid based on the provided information.

If dredging volume is much different from the assumption, a modification will be done to include additional contract time.

The disposal facility shall be determined by the Offeror and the Offeror shall provide their bid based on the disposal facility selected.

Although it is specified that YOHORI is 0.3m, in case that the depth of water is more than - 0.9m, the depth of YOHORI at the bottom is 0.6m and the width of YOHORI is 4.0m according to the estimate standard by the Japanese Government (Kokudo Kotsu Shou).

And it looks difficult to meet 0.3m, is it possible to change it?

Government requires the dredging depth shown in drawing and consider the YOBORI volume 0.3m.

Offeror can dredge only depth to keep the required dredging depth. But government will count the dredging volume with required depth plus YOBORI 0.3m.

According to the drawing, required dredging depth is 11.0m from C.D.L.

However, it is assumed that the survey error might affect the accuracy of dredging when managing the production.

Is it possible for Gov to modify the dredging depth from -11.0m to -11.2m?

Government requirement for dredging depth is 11.0m from C.D.L.

Contractor shall provide accurate survey.

Regarding hoisting work for pontoon, is it possible for workers to perform drainage work on the pontoon while it is hoisted at sea level by a floating crane?

The decision to perform drainage work of the pontoon is the Contractor’s responsibility. The Government requires the sunken pontoons removed and disposed of.
