Describe parameters and basis used for $1.0M to $5.0M engineers estimate

Per ER 1110-2-1302, cost estimate data is considered confidential, sensitive, proprietary, and For Official Use Only. Sharing of this data is restricted since disclosure may easily compromise the integrity of competitive bidding processes.

Elaborate on concerns over unexploded ordinance and specified restriction that prohibits use UW arc welding and cutting torch equipment req’d to secure rigging, Please refer to Specification 01 11 00 which states that no cutting or welding is allowed during debris relocation operations. There is not a MEC/UXO concern for welding/cutting. The requirement for not welding/cuting is a Cultural Resources requirement to preserve the potential historic items. This requirement was reiterated in the 01 35 16 Section since diving requirements were largely covered in this section.

Provide copies of regulatory permits and/or clarify turbidity restrictions when conducting dredging, transporting and hoisting debris above water surface @ designated location.

Copies of the regulatory permits were attached at the end of the specifications package.

At what juncture during pre-bid and solicitation process is contractor required to identify and commit using designated subcontractors for this offer?”

There is no requirement to identify and commit to using designated subcontractors during pre-bid or the solicitation or process.

The RFP Project Drawings provide a brief description of each of the 25 debris objects scheduled to be moved. However, the debris object description doesn’t include size, weight, or material. Can the USACOE provide the estimated size, weight, and material of each debris object?

AGS provides some data in their “Sidescan Sonar Report” starting on page 402 of the specification, but it isn’t clear if this correlates and should be used in bidding.

Please refer to the descriptions of the debris objects on the plan sheets and the 511th EDD report which provide the anticipated length, width, and height. The weight is unknown. The description of the debris objects on the plan sheets were obtained from the "side scan sonar report" from AGS.

What is the protocol if a debris object cannot be found in the location shown on the project drawings?

Please refer to Amendment 0003 which has revised Specification 01 11 00 1.2.1 which has clarified the protocol.

What is the protocol if a debris object breaks apart during movement? What is the maximum size of debris that can be left in location? We note that divers are required to be out of the water during initial lifting and final placement of debris per MEC protocols for unintentional detonation.

Please refer to Amendment 0003 which has revised Specification 01 11 00 1.2.1 which has clarified the protocol. Correct, please refer to Specification 01 35 16 regarding the requirement for divers to be out of the water during initial lifting and final placement of debris per MEC protocols for unintentional detonation.

Section 01 11 100 Summary of Work, paragraph

1.5 notes “The Contract shall obtain…all licenses and permits required…” What other licenses and/or permits are required for this project?

All the permits are attached at the end of the specifications package. The contractor is responsible for all other licenses and permits per Clause 52.236-7 in Specification Section 00 72 00.

Is jetting allowed to expose debris objects before rigging and moving them? Yes, jetting is allowed.

To what depth will the debris objects be found?

Section 01 35 16 MEC Construction Support Operations, General Paragraph requires “the area must be cleared to depth of work by qualified MEC Divers prior to non MEC divers entering the area.”

Please refer to Amendment 0003 which has revised specification 01 35 16. The depth of work depends on how deep the Contractor needs to excavate to perform the work, e.g. if the Contractor needs to water jet sediment under a Large Object which is -3 feet bellow the mud line, then the depth of work in that specific area is - 3 feet. Depth of detection to clear an area is dependent on the equipment provided by the UXO contractor and possibly the proximity of other ferrous objects in the area, and may need to be cleared as the excavation is being conducted, often in one foot lifts.

What is the process if a ship needs to access the berth while the debris object relocation is underway?

Please refer to Amendment 0003 which has revised Specification 01 11 00 1.2.1 which has clarified the protocol.

Will the Army/USACE will let us keep a small boat in the Barge Dock area so we can shuttle the work crews out to the work barge each day?

Please refer to Amendment 0003 which has revised plan sheet G-004 that shows the barge dock area and can be used to shuttle personnel every day.

Context: In the drawing C-102 for example Point ID B28 lists 3 objects for relocation. It’s understood that along with B32 showing 2 objects for relocation equals the 16 targets total for that CLIN. The SSS Contact Reports starting on page 397 of 648 i.e.B18, B20 and B24 indicate “objects in debris field,” “Surrounded by objects” etc.B35 Question: What if there are similar size object(s) in those fields? Are contractors only responsible for the items identified by the GPS coordinates.

Please reference the Plans. Contractor is responsible for the relocation of the debris objects that are identified on the plan sheets. If there are similar objects in those fields, but the similar objects were not identified to be relocated on the plan sheets, then they don't need to be relocated.

The debris objects to be relocated have the GPS coordinates identified on the plan sheets.
