QUESTION GOVERNMENT RESPONSE

RFP Package;

Attachment(3) h(3)_1624524

Electromagnetic & Hydrographic Equipment:

The RFP package included attachment 3 which lists very detailed (to include manufacturer name and model number) information on equipment which has been approved for use. Can the Government clarify if the exact equipment listed must be used, or if bidders are allowed to use equipment from other manufacturer's which perform similarly to the equipment specified by the Government?

The Electromagnetic and Hydrographic Equipment to be used by the contractor awarded this requirement must be approved by the Naval Ordnance Safety and Security Activity (NOSSA). The awarded contractor is NOT required to use this exact equipment.

However, the list of equipment in Attachment (3) was used during Phase I Dredging. Attachment (3) is included to inform all bidders of the previously used equipment.

If the awarded contractor intends to use different equipment, then it will require NOSSA approval prior to being used. It does not need to be approved prior to award.

Sediment Disposal:

The cost for sediment disposal will be based on assumed quantities of contaminants listed in the Chugai Technos Test Report which starts from PDF page 217 of 269 of Atch(1)_1624524-SPEC. In the event contaminant(s) not listed in the Chugai Technos Test Report are encountered will the contaminant(s) be considered a "Changed Conditions" eligible for compensation?

Changes to the specifications will be executed in accordance with 52.243-4 Changes.

Changes in quantities will be executed in accordance with 52.211- 18 Variation in Estimated Quantity. See para “Variation in Estimated Quantity” in General Information in the IFB.

General Description of Work #2

Anomalies:

The quantity of 150 metal anomalies is listed in the RFP package;

in the event that quantity turns out to be higher will that be treated as an "unforeseen condition" eligible for compensation?

Changes to the specifications will be executed in accordance with 52.243-4 Changes.

Changes in quantities will be executed in accordance with 52.211- 18 Variation in Estimated Quantity. See para “Variation in Estimated Quantity” in General Information in the IFB.

Para. 1.4.1.2;

Exclusionary Period:

During the period of "work stoppage" between April and October, is it possible for the Contractor to conduct non-dredging related work such as sampling of sediment, magnetic surveying, underwater surveying and depth and shallow surveying?

Yes, it is possible.

Sec 01 11

00.00 33;

Para. 1.4.1;

Period of Performance:

On an assumed award timeframe of early November 2021 (90 days after the bid date) the Contractor would have until the end of March 2022 (about 4.5 months) to complete all contract specified pre-construction safety & environmental documentation, coordinate permits with various host nation authorities, coordinate and finalize disposal venues for dredged materials, and conduct all required pre-dredging surveys. Actual dredging would not start until December 1, 2022 after the April to November exclusionary period has passed. This means the Contractor will have about 121 calendar days (until Mar 31, 2023) to complete all of the dredging.

Once the anticipated weather delay days (01 32 16.00 33, para.

1.3.1.1), weekends and US holidays (01 14 00.00 33, para. 1.3.4) and Japanese New Year's observances are subtracted from the 121 calendar days, the actual time the Contractor will have to complete all of the dredging, associated surveying and acceptance inspections will be roughly 78 working days. In light of all of the coordination required, the 78 working days is really cutting the schedule close. Would the Government consider modifying the specified period of performance of 540 calendar days?

The 90 calendar days will be extended to finalize report and document after dredging works.

See Attachment (5).

Overnight Berthing:

This section states that overnight berthing of Contractor's vessels will be limited to just (2) two; however, this type of operation requires a larger number of vessels for it to be done safely and efficiently. Will the Government reconsider the specified quantity of (2) two vessels?

There is no limit number of vessel berthing and floating-equipment if there is no impact with ship operation and it is approved by Port Ops.

Over depth Dredging:

In regard to over dredging, does the 30 cm allowable over dredging depth also applicable to the side slopes that are within the "dredging limits", or is that applicable to just the flat (horizontal) seabed?

The 30 cm allowable over dredging depth also applicable to the side slopes that are within the "dredging limits".

Down time Compensation:

This section states that Contractor will be compensated for any downtime caused by rescheduling brought about by emergency use of the dredging area by the military.

Question 1 - How can Contractors best reflect a single hourly rate for the multiple work tasks which could be impacted by an "emergency use" situation requiring a demobilization and remobilization and which each carry a significant cost difference?

Examples of planned work tasks which have significant costs differences include crane barges used for deploying and retrieving framed silt fence, divers for removal of non-hazardous anomalies, dredger and transport barge during actual dredging operations.

Question 2 - Will the hourly rate(s) also apply to time associated with demobilizing and remobilizing, or will the hourly rate(s) be applied only to the time the Government uses the dredging area under the "emergency use" provision?

Question 3 - To safely shut down work operations and demobilize due to an "emergency use" situation a minimum of six

(6) hours would be needed. How much advance notice can Contractors expect to receive in an "emergency use" situation?

Question-1:

The hourly cost of dredging work should be reflected as down time.

Question-2:

The hourly rate(s) will be applied all the effort of the time for Government uses the dredging area under the "emergency use" provision.

Question-3 The Government intends to issue the "Suspension of Work Order" 14 calendar days prior to suspend the Contractor's work.

See spec 01 14 00. 00 33 page 2, para 1.2.2 Government Emergency Use Scheduling Requirements.

Site Investigations:

Electromagnetic surveys are required to be conducted prior to dredging and surveys are more effective if conducted when there aren't any berthed crafts in the way; will the Government have all watercrafts cleared from the area to be surveyed or are Contractors expected to work around them?

The Electromagnetic surveys is performed when the ship is not berthed. The Port OPS will coordinate the ship operations in India Basin to enable Contractor to complete the Site Investigations works within 90 days.
