are to be driven to an ultimate capacity of 175 kips. Specification 31 62 16.13, paragraph 1.4.2 says piles are to be driven to obtain a bearing capacity of not less than 230 kips. Please clarify which is correct.

The piles are to be driven to an ultimate capacity of 230 kips. Please see Amendment Continuation Page.

Paragraph 3.6.1, is not applicable to this contract. Please see Amendment Continuation Page.

There isn’t any space or location set aside for a contractor field office. It is presumed, but not required, that the contractor will have an office on a barge at the work site.

There is no requirement to provide an office for government use during the contract.

16 Specificati on 01 50 00

Page 9 3.6.1 Does section 3.6.1 intended to describe what is required for the Contractor's field office, or is the office being described to be provided to the government for government use during the project?

19 Drawing Package - Demo Set

G-002 Under the "Summary of Work" section, there are numerous references to original as-built drawings being available upon request. Please provide all as-built information regarding the existing structure. Of particular interest is whether the annular space between the foundation structure pipe sleeve and the driven pipe pile is grouted, whether the driven pipe pile is filled with concrete or grout, the dimensions and thicknesses of the top concrete deck and any weight

Page 2 3.1 There is reference to a specification 33 71 02 Underground Electrical Distribution but this does not appear to be included in the specification documents. Would you please provide?

All medium voltage cable testing is covered under Section 26 20 00. Section 33 71 02 is not applicable and thus was not included in the specifications.

You have included specification section 13-34-19 Metal Building Systems. This specification is for field fabricated buildings. Can the specification be changed to include Prefabricated Buildings? Where the structure would be fabricated in a factory.

The Navy does not have an active pre-fabricated specification, only 13 34 19 Metal Building Systems, but factory-assembled structures that meet the requirements of 13 34 19 can be submitted for review and acceptance.

1.5.8 An underwater Dive QAQC team is

required to monitor underwater activities. Please clarify specifically what scopes of work they are to inspect and frequency? Are they required to simply inspect the DCS structure upon completion. We assume they don't need to be on site the entire time. Also, if required to also inspect the cable installation that is being jetted into the ground there isn't anything for them to inspect. Please confirm.

Section 1.5.8 will be deleted. Please see Amendment Continuation Page.

34 Section 01 50 00

Page 9 3.6.1 Section says "Provide and maintain administrative field office facilities within the construction area at the designated site." Will the government be providing space in Fort Trumbull Park or elsewhere as the designated site? Are we allowed to setup an office trailer and park at Fort Trumbull park visitor center?

Paragraph 3.6.1, is not applicable to this contract. Please see Amendment Continuation Page.

No space will be provided at Fort Trumbull or elsewhere. No office trailer will be allowed at Fort Trumbull. No office of any kind is required for the government.

Based on previous projects of this type, expectation is that the contractor may want an office on a barge at the work site.

Progress meeting locations will be arranged by the Construction Manager.

West Elevation Detail on Drawing S-103 references Detail A1 on drawing S-505 for the details of the anode connection. Drawing S-505 does not have a Detail A1 nor any details on the anode connection.

Please provide this detail.

The contractor should assume That 2 - 6" long C3x6 channel will be welded to the structure, for each anode, with a 3/16 fillet weld. The anode will then be bolted to the channel. The weld should be coated but there must be an electrical connection between the anode and the channel.

52.211-12 a LD scheduile section 52.211-12 appears to dictate that above water sections of pile must be removed prior to 7/15/2024 and then piles below water by 8/30/24 and there is a 1 day break between. Are piles allowed to be removed below mudline prior to the 7/15/2024 date and prior to the 1 day break? If not, please confirm that the sequence of demolition would require the piles to be cut at mudline and that the section of pile below mudline must be removed seperately from the section of pile above mudline.

Yes.

Page 2 1.2.1 In addition to an earlier question about the Protected Species Observer requirements, please specify how many observers are required and where they need to be stationed (on the vessel doing the work or some distance away from the work on a boat).

The contractor shall determine the appropriate number of Protected Species Observers (PSO) to adequately monitor the work zone and zones of influence to ensure that the project can be completed without any takes of marine mammals.

For prior projects at SUBASE, a minimum of three PSOs were deployed with one PSO located on land to monitor the work zone and two located on a boat in order to monitor the zones of influence.

The marine mammal monitoring work plan shall detail the contractor’s proposed approach. Refer to the response to RFI #18 for additional details regarding the marine mammal monitoring plan.

51 1 01 14 00 1.1.b. Referenced specification states that the DCS Tower will remain in operation during construction and the Contractor must conduct his operations so as to cause the least possible interference. The Milestone 1 date for new construction being complete is 6/24/2024 and the start of demolition as 5/15/2024. Please clarify this discrepancy of the demolition date being before the completion of the new tower. Is the demolition allowed to start prior to completing the new construction?

Demolition has to start by 5/15/2024. It is allowed to start before completion of the new construction
