SUMMARY OF CHANGES

SECTION SF 30 - BLOCK 14 CONTINUATION PAGE (SF 30)

The following have been added by full text:

AMENDMENT 0004

This Amendment 0004 is issued to incorporate the following:

1. Provide responses to Pre-Proposal Inquiries (PPIs)

2. Updates to the Solicitation and Standard Form 1442:

a. Update the proposal due date to reflect the current due date of 31 March 2023

b. Update the number of copies to be provided with the proposal

3. Update to clause 52.211-12 LIQUIDATED DAMAGES--CONSTRUCTION (SEP 2000) (changes denoted in red below)

1. Responses to Pre-Proposal Inquiriries (PPIs)

Question No.

Reference Question Government Response

Page Section Para.

Drawing Package

Page G-002

Under "Possible Work Sequence" section, Number 3 describes grouting and welding the piles in place after driving them. Does this mean grouting the annular space between the 22" diameter base frame template pipe and the 20" pipe pile? We don't see any reference in the drawings to grouting this annular space, only grouting the outside of the 22" base frame template pipe utilizing the fiberglass jacket and there is reference to filling the pile with grout up to +4.ft EL. If grouting the annular space between the 22" base frame template pipe and 20" pile is also required, this would typically require some kind of built in seal on the bottom of the 22" base frame template pipe where no fabrication provisions appear to be detailed for this.

Please clarify the requirement.

There is no requirement to grout in between the 22" rigid frame and the 20" piles.

Please clarify.

of fabrication done in the field and the number of sections assembled in the field is up to the contract to decide what is the most efficient method for them. Dwg. S-105, South Elevation - Detail B3 indicates that columns and braces between platform levels are typically welded with all around CJP groove welds. If the fabricator decides that certain locations require a field weld (depending on the preferred assembly sequence/procedure) then they can use field welds as a substitute for shop welds.

12 Drawing S-106 Detail C5

Is Specification 31 62 19.15 intended to also cover the fiberglass housing (split) shown in Detail C5 on drawing S-106. The particular item is not mentioned in the spec nor elsewhere that we can see.

The specification in this case is pertinent to the housing (form) material only. The thickness of the fiberglass housing shall be 1/2" thick.

Instructions to

Proposers 00 21 16 Factor 4

Factor 4 evaluation as described on page 14 of 75: May PPQs that have been completed for prior NAVFAC RFPs be acceptable if we are planning on using the same reference projects in Factor 1 or must we get new PPQs completed for those same projects?

Yes, this is acceptable.

Specification 01

50 00 Page 11 3.8

Is the temporary project safety fencing required around the Range House and the shoreline where the cable ducts are? It is not clear where the safety fencing is required.

Temporary safety fencing is required between the range house and water where the cable ducts are and in the area where the platform for external transformer and other equipment will be mounted. Expectation is the platform will be in the vicinity of the external stairs on the Fort Trumbull side of the building.

Specification 01

57 20 Page 2 1.2.1

It appears we have to submit the qualifications of the Protected Species Observer. It is not clear what the specific requirements are for observation. Are we to hire a Protected Species Observer only during pile driving and extraction, or during subsea cable installation as well? Please specify.

Protected Species Observers (PSOs) are required to monitor to ensure that the project can be completed without any takes of marine mammals.

Underwater sound resulting from pile driving and extraction activities has the potential to harass marine mammals.

Other construction elements, including installation of the DCS structure, sensor array, and Main Power Cable, do not have the potential to result in harassment under the Marine Mammal Protection Act (MMPA).

A marine mammal monitoring plan shall be submitted to NAVFAC for review and approval prior to initiating in-water work. The monitoring plan shall document the following: number of PSOs and locations of PSOs during pile driving and removal; figures showing the proposed 10-meter shutdown zone if a marine mammal enters the work zone to avoid collision with project vessels; figures showing the proposed disturbance zones to be monitored; proposed data form to be used to document monitoring and marine mammal observations;

conditions under which monitoring will be conducted; and proposed mitigation measures to preclude marine mammal takes, including pre-activity and post-activity monitoring.

Data forms documenting the marine mammal monitoring shall be provided to NAVFAC on a weekly basis when monitoring is required. In addition, an annual report detailing the monitoring protocol used, summarizing the data recorded during monitoring, and documenting any shutdowns required to avoid takes shall be submitted for each year in which monitoring by PSOs is conducted.

Specification 31

62 16.13 Page 10 2.2.5.1

There is language in this section pertaining to no splicing in the top 25 ft of the pile to eliminate coating vulnerability. We haven't located specifically where the drawings or specifications indicate the actual length of coating required on the pile. Is only the top 25FT of the driven piles to be coated?

Spec. 09 97 13.26, Section 3.1 indicates that all exterior steel surfaces are to be coated. The piles will be fully coated, the entire length.

Drawing

A turbidity curtain is required to be used for work activities related to the demolition of the existing DCS and construction of the new DCS. A turbidity curtain is also required during all construction when working within 10ft of the toe of the riprap. A turbidity curtain is not required for work related to the installation of new cables or the removal of the old cables and sensors.

clarification where and when curtain is required. Is curtain required around the New DCS platform install location and around the old DCS structure during demo only? Please confirm curtains are not required during the underwater work (installing new cables and removal of old cables and sensors)?

Confirmed, PPIs are due seven (7) days prior to the current proposal due date.

32 SF1442

SF1442 says the contract duration is 394 calendar days. This is also mentioned in Factor 2 requirements on page 11 of 75, however Section 52.211-12 LIQUIDATED DAMAGES states a 365 calendar day requirement.

Please clarify which is correct.
