Reference Question Response

Page Section Paragraph

1 Page 37-38 of 54

Solicitation Based on tight scheduling time frames for each phase and high liquidated damages for the work phases included in the contract documents,(5 of 12 at $75,000/calendar day) the financial risk associated with this project is high.

For example, a project of this size takes at least a minimum of 2-3 months for adminstrative & safety related submittals prior to starting construction due to the required 20 working days for Government review/approval allowed in the specifications. Similar to all projects bid this time of the year, the project will be awarded at the end of September. If the contractor is unable to start the project until the end of the 2020 calendar year on the first phase of work, we will be limited to only 3-4 months out of the alloted 6 months to execute the first phase of work. In addition, this does not account for any potential delay of:

long lead procurement items (flood gates), weather days, and government holidays. Additionally, a delay in the first phase of work affects all subsequent phases.

UPDATED REPONSE: See revisions to the Milestones and Liquidated values. Dates are planned to work around Dry Dock and Berth Projects, as well as other construction projects within NNSY. If the contractor needs to plan to work 2 or 3 shifts, or weekends during the begining of the project, or any phases to complete the dates, it's their responsbility. The intent of the early start is to incentavise the contractor to start work as soon as possible. LD's have been removed from Phase 1, but time period and LD's remain for Phase 2.

Please re-evaluate and provide your detailed schedule for each phase of work because at this time, it is uncertain any phase can be properly accomplished within the specified time frames. In addition, please reconsider the current use of specific timelines for all 12 phases and eliminating liquidated damages for each specific phase.

2 Page 37-38 of 54

Solicitation Please consider allowing the contractor to work in multiple areas at once. This gives the contractor (and their respective subcontractors) the flexibility to share resources between the different phases and does not limit them to single areas. Any flexibility that can be provided will lower the bid price and the overall project becomes more manageable. We suggest: Eliminating the phased liquidated damages and have definitive timelines for the work around the dry docks/waterfront but allow the other phases to be fill in work with no definitive time lines.

See revisions to the Milestones and Liquidated values. The phasing is planned around Dry Dock and Berth Projects, as well as other construction projects within NNSY. The phasing is also spaced out to minimize the contractor work areas to become excessive and impact NNSY activities.

3 Page 37-38 of 54

Solicitation Due to the inherent risk associated with this project's phase work approach, and the tight timelines and substantial liquidated damages associated with 5 of 12 of them, we request 3 additional weeks to prepare our proposals and bidding package.

Please see Amendment 0002.

4 Page 37-38 of 54

Solicitation Why are the liquidated damages for Phases 4-8 $75,000 per calendar day delay? This seems high. As you know, the liquidated damaged values should be reflective of the actual potential damages the Navy could incur due to this delay. In accordance with published Naval Facilities Acquistion Standards (NFAS), has

See revisions to the Milestones and Liquidated values. These are estimated cost in damages to the NAVY, if the work is not completed by those dates.

this analysis been accomplished and approved by the Echelon II/IV Chief of the Contracting Office (CCO)?

5 Page 8 of

Solicitation Due to the rare occurrence of $20M construction contracts related to this type of work in the past 10 years, since this overall solicitation has 12 separate smaller phases, (in an effort to promote more qualified competition), please consider reducing the relevant construction projects to a minimum of $15M or greater construction costs within the past 15 years.

Please see Amendment 0002.

6 Page 1 of

Solicitation Due to the tight timelines for the phases work and and substantial liquidated damages, please consider reducing the bid acceptance period of 120 days to 60 days.

Bid acceptance period remains unchanged.

7 Is it possible for the caissons to be taken out of Norfolk Naval Shipyard, to an off site facility, to be repaired in accordance with the design documents?

UPDATED RESPONSE: See revisions to the Milestones and Liquidated values. There are two time slots for Phase 6.

From 3APR21 to 3OCT21 the contractor can remove the Caisson #3 to an offsite location to be worked on. The contractor needs to complete the wing walls and flood wall work from STA 9+05 to STA 10+95 by 3OCT21. Caisson #3 needs to be installed for government inspection by 16SEP21. Any remaining work on only the flood wall can be completed in the second window of time 19JUL22 to

28NOV22.

8 14 of 54 4 4.1 Is this site visit mandatory for all bidding contractors to attend?

The site visit is not mandatory.

However, this will be the only government sponsored site visit for this project.

9 14 of 54 4 4.1 Does the site visit include walking into Controlled Industrial Area’s that we will need to request access via CVS-CIA spreadsheet? Or is Controlled Access something we DO NOT need to request for this site visit?

The site visit includes walking into the Controlled Industrial Area. The request is needed for CIA access.

10 SWBS- 37 622 d.1 This section includes, but is not limited to NEW fiberglass reinforced plastic (FRP) grating, and its framing for ballast tank sump grating, stair landings and catwalks. Is it the intention to replace ?

17 Solicitation

3.3 In section 3.3, (1) Factor 1, Experience, it states “Projects submitted for the offeror shall be completed within the past ten (10) years from the date of issuance of this RFP.” Due to the limited amount of similar types of projects completed in the past ten (10) years, will the Government consider changing this requirement to the following language to increase the breadth of submitted project experience: “Projects submitted for the offeror shall meet one of the following requirements in relationship to recent experience

1. Completed project within in the past ten (10) years from the date of issuance of the RFP or;

2. Current project under construction that shall be at least 75% complete by the date of issuance of the RFP.”

Please see Amendment 0002.

18 Drawing G-

Drawing G-106 Phase 6 notes to base bids for ongoing submarine repairs in Drydock 3 starting in September 2022. The liquidated damages schedule notes that Phase 6 starts on July 19, 2022. This only leaves less than 6 weeks complete caisson rework and other associated work.

This timeframe is not feasible. Please revise the timeframes to provide adequate time to complete this work

There is a separate window for the upgrade of caisson #3 and raising the wing walls at DD3 caisson seat. (3 April 2021 - 3 October 2021) The intent of phase 6 is to build and tie-in new flood wall to newly raised wing walls at caisson seat. The two phases should allow enough time to finish all caisson, caisson wing wall and new flood wall work without impacting ship avaliability work in DD3.

19 8 of 54 Solicitation Factor 1, Experience

1. The Solicitation Submittal Requirement for Factor 1 Experience requires that projects submitted for the offeror shall be completed within the past (10) years from the date of issuance of this RFP. Please consider changing the requirement to the project shall be completed within the past (20) years.

Please see Amendment 0002.

21 33 00700 Can NAVFAC provide any clarity how they will address the contract execution of this project relative to the current COVID-19 outbreak in relationship to Guidelines and Orders that currently exist at the shipyard or potentially be modified due to this ongoing unprecedented event;

particularly working within tight and restricted barricaded areas? Is NAVFAC considering to adjust any current contract language during this pandemic relative schedule and/or cost relief?

Contract language remains unchanged.

22 37 52.211-11 (b) Phase 1 duration in Amendment 0001 was lengthened to 235 calendar days and the duration for Phase 2 was shortened to 57 calendar days. Please confirm this is the intent and that the Government requires Phase 2 to be completed within this time frame at a rate 10.70 lf per calendar day while all other phases are required to be performed at an average rate of 3.83 lf per calendar day . This duration doesn’t seem reasonable or consistent when compared to the other durations on the project.

Please see Amendment 0002.

23 37 52.211-11 (b) The phasing schedule shows Phase 10 ending at station 31+15 and plan sheet G-111 shows 32+15. Please confirm which is correct.

UPDATE: See Amendment

24 37 52.211-11 (b) The phasing schedule shows Phase 1 ending at station 47+10 and Phase starting at 46+50. Please confirm which is correct.

UPDATE: See Amendment

25 37 52.211-11 (b) The phasing schedule shows Phase 8 ending at station 21+20 and Phase 9 starting at 21+00. Please confirm which is correct.

UPDATE: See Amendment

26 Can the Navy furnish a detailed construction schedule per phase?

This could be beneficial to help estimate the project. There remains a scheduling concern regarding the tight timlines to perform some of these phases of work with the multitude of government approved submittals and outages that will be required for this project that are required to allow the government at least 20 working days for review of submittals and at least 28 days for processing utility outages.

The work has been planned around the requirements of NNSY. The governemnt recommends applying for outages, surveying existing conditions and other items well in advance of the Div 1 timelines.

27 SWBS It is our understanding that Dry Dock #3 will have a boat in it (as a part of Phase 6) when the caisson is supposed to be removed, taken off-site, and repaired. Please confirm the schedule when Caisson #3 is required to be repaired off-site.

See revisions to the Milestones and Liquidated values. There are two time slots for Phase 6.

From 3APR21 to 3OCT21 the contractor can remove the Caisson #3 to an offsite location be worked on. The contractor needs to complete the wing walls and flood wall work from STA 9+05 to STA 10+95 by 3OCT21. Caisson #3 needs to be installed for government inspection by 16SEP21. Any remaining work on only the flood wall can can be completed in the second window of time 19JUL22 to

28NOV22.

28 34 Solicitation 52.228-5 FAR 52.228-5 is included in this solicitation, but there are no insurance requirements or minimum limits listed. Please clarify the Minimum Insurance Requirements for this project.

Refer to spec section 01 30

00.00 22, Part 1, 1.4 Minimum Insurance Requirements.

32 16/54 4.2.3 1 If electronic bid is not allowed, may contractor allowed to meet a NAVFAC representative outside the secured perimeter to submit the bid, Similar to the Dry Dock 4 Bid?

See Amendment 0005

33 1 01 11 00 1.2.1.i Line 1.2.1.i notes "Remove terracotta duct banks and provide with split casing conduit and concrete encasement." Split casing conduit is normally used when existing wires must not be maintained rather than removed and replaced. If this will require the existing ductbanks will have to be removed by hand demolition in small pieces rather than larger sections. Can the existing wiring be removed and replaced?

Refer to the manhole survey (Appendix F1) for the labeling of wires. In most cases, the conductors are not specifically identified. It will be extremely difficult for anyone in the Government to identify all conductors (power and/or comm); therefore the wires will be protected by the split casings and the duct will be encased in concrete. No wires will be removed/replaced.

34 1 01 11 00 1.2.1.i Please confirm the existing duct banks are not to be considered a contaminated or hazardous material.

With the duct bank being required to be demolished by hand will all the contaminated and hazardous requirements for removal be required such as the use of a licensed contractor performing that work, tenting the work and all the appropriate personal protective equipment?

The existing ductbanks are either vitreous clay ducts or fibrous ducts; both encased in concrete. The fibrous material is not a hazardous material and is a non-conductive fiber (wood) mixed with coal tar.

The duct bank can be demolished without special requirements.

35 1 01 11 00 1.2.1.i The hand demotion and special handling of the duct banks will have a major impact on the schedule in each phase, please allow the duct bank work to be completed prior Phase work beginning.

special handling is not required.

3.2.7 Within this paragraph it notes to

"Allow bituminous pavement to cure for at least 21 days before paint is applied." Please confirm the completion of the final striping in each Phase does not have to be done by the Acceptance Date and is not subject to the noted Liquidated Damages.

Contractor should plan to use Thermoplastic. Thermoplastic is to be required for all traffic markings. Thermoplastic Alkyd pavement markings may be applied directly after paving operations provided all other conditions in specification section 32 17 23 paragraph 3.2 are met.

38 1 Solicitation Block 13 A Additional time is requested due to the strict schedule requirements, high liquidated damages and technical planning required to prepare this bid.

It would be in the best interest of the government to all this extra time for bidders to prepare a thorough bid.

We request an additional two weeks to prepare our proposal.

Please see Amendment 0002.

39 SF-30 Block 14 Continuation

Per amendment 0001, first PPI response, it is allowed for phase 1 and phase 2 to “overlap”. Is it the government's intent to allow phase 1 and phase 2 to run concurrently and maintain each phase respective completion date milestone? if so, will there be a duration constraint on phase 2, as currently the phase constraint is 57 days. Also, should the phase 1 'Phasing-Comment' language be revised to address the allowable "overlap" work. Please clarify.

40 37 52.211-11 (b) Prospective bidder is extremely concerned with the significant Liquidated Damages contained in section 52.211-12 assigned to the various phases of this project. The damages assigned to phase 4 through 7, appear to be unprecedented when considering the potential compounding and stacking effect (Compounded LD’s could be as high as $11,250,000.00 per month just for Phases 4 through 8) of large LD’s for this project size, scope and aggressive interim phasing durations. Following are some key challenges that further shift significant schedule risk to the prime contractor which amplify the concern even further:

1. Impacts arising from the Coronavirus, especially the supply chain impacts that have impacted the industry thus far along with the social distancing requirement that present themselves in the confined small interim work phases inherent to this project.

2. Modifications of ship work required to Dry Dock Caissons 1 and 3, has raised some significant concerns from Shipyards citing that the short interim phase durations where caisson work occurs present significant challenges to shipyard availability and operations coupled with large LD’s that shipyards will not support. These conditions present concerning schedule issues and a significant transfer of risk to prospective prime bidders who rely on the shipyards availability and acceptance of prime contract flow down terms since the prime contractors have no way to remedy these delays.

3. The completion of site investigations, shop drawings and submittals for this project is significantly impacted by the inherent phasing plan which affects the prospective bidder’s ability to perform investigations and submittals early in the project for all phases, and effectively reduces the working time in each phase.

Prospective bidder requests

Liquidated Damages have been revised due to changed conditions at NNSY. Item 1 Response: Understood, but this contract makes it the responsibility of the contractor to work thru those challenges.

Item 2 Response: See revisions ot the Milestones and Liquidated values. Item 3 Response: Investigation work, exisiting conditions documentation will be allowed to take place in advance of the actual phased work to advance the work successfully. See revisions to the Milestones and Liquidated values.

NAVFAC consider the following to allow to mitigate significant risk transfer to prospective bidder:

A. Reduce the significant LD’s in the interim phases 4 through 8.

B. Allow bidders to work in select multiple locations at once with access and coordination provisions for shipyard operations and other contracts.

C. Consider allowing some of the shipwork modifications to caissons in place which may support longer overall durations.

41 37 52.211-11 (b) Can NAVFAC provide more clarity/definition to the phase '240 Linear Foot Construction Work Area Limit' when working within a phase?

Does this mean that all construction must be fully complete for any 240' section within any given phase? Or is the intent not to have, say, an open trench greater than 240' for any given phase?

See revisions to the Milestones and Liquidated values. The 240 LF Construction Work Area Limit was emphasized to help the contractor manage safety requirements, and damage to subgrade. Per the specifications the contractor is responsible for these items.

The government has removed this requirement. If the contractor does not demonstrate good practices, non-compliances are written, then they will be at risk for the requirement to be enforced. It is acceptable for the contractor to pave and pavement mark the project in one mobilization, as long as it is compelted before the milestone date.

42 1 Solicitation 13 Due to the complex nature of this project will the Navy extend the current bid date by 2 weeks?

Please see Amendment 0002.

116 SWBS-8 70 b Perform and submit the results of an inclining experiment as the basis of the contractors responsibiility in determining the values of displacement, vertical center of gravity, list and trim of the Saisson at its design displacement, supplemented by the weight control program and amount of permanent concrete ballast, if nessary, to establish the required lightship draft and minimun GM at the lightship condition. How much permanent concrete ballast is expected to be added?

No additional ballast concrete is anticipated. Transverse metacentric height (GMT) is shown on sheets SA601 and

SA602.

117 CU Sheets In reviewing construction and pavement demolition limits, these limits are not adaquate due to the conditions and nature of the underground work required as part of this project. Will additional pavement removal and replacement beyond the limits shown on the plans be paid as a change condition? Also,will the limits of construction be able to be increased in order to complete the work?

Project limits are indended to maintain a tight, linear work area. Pavement demoltion and repair limits are set with this in mind. Refer to 31 23 00.00 22 for sheeting and shoring requirements where needed by contractor to acomplish construction.

118 333000 1.3 There is not enough information provided in the specifications or on the plans to be able to identify the flows that will require bypass pumping, and the existing system configuration in order to determine how many temporary bypass pump setups will need to be installed to maintain the operations of the Shipyard. In order to provide an accurate bid, please provide more information for bypass pumping of the existing sanitary sewer system that will be required in order to complete the work for this project.

See Amendment 005

119 334000 1.3 There is not enough information provided in the specifications or on the plans to be able to identify the flows that will require bypass pumping, and the existing system configuration in order to determine how many temporary bypass pump setups will need to be installed to maintain the operations of the Shipyard. In order to provide an accurate bid, please provide more information for bypass pumping of the existing storm drain system that will be required in order to complete the work for this project.

120 312300.002 2.3 Please clarify backfill requirements for casing located beneath the flood wall footing. Per the last sentence of this specification it requires CLSM from the bottom of the cutoff wall to the bottom of the casing excavation.

Does this apply to all utilities within the floodwall footprint regardless of utility elevation? If this is meant to apply only to utilities located below the bottom of the cuttoff wall, this conflicts with detail A1/CU502 which requires "low permability fill" from top of bedding to 1'-0" above the bottom of the cutoff wall. Please clarify.

See Amendment 005

121 CU Sheets The CU 400 series of drawings requires valve vaults to be constructed on existing lines or connected to existing lines, and these lines are required to be cutoff flush with the valve vault wall. This will not be possible on existing lines.

Please revise to allow existing lines to protrude into the vault.

Existing pipes may extend into the vaults as long as they do not interfere with operation of valves or gates controlling flow through the vault.

122 33 40 00 Storm Drainage Utilities does not call for any type of field testing of the valve vaults or slide gates. Please confirm that visual inspection of the work is the only requirement

See Amendment 005

123 35 2014, 35 20 16.33, 35 20 16.59

Spec Sections 35 20 14, 35 20 16.33 and 35 20 16.59 for the different types of flood wall gates and stoplogs require that 10% of gates be tested per manufactures instructions. After consulting with one of the manufacturers, they stated that their normal field inspection of the installation and operation was suffice for their certification of gate installation. Since it is unlikely that we will actually have a major flood event after the gates are installed, will the contractor be required to build a temporary water containment barrier at the gates selected for testing. If this

The contractor will be required to build a temporary water containment barrier at the selected gates for testing.

Selected gates for testing must be approved by the Contracting officer. Intent is that minimum 10% of each gate type be tested.

is required, will (1) test for each type of gate (total of 3) be sufficient for the 10% test requirement since there are (27) total gates/stoplogs on the project.

Can you define "Navy Shipyard Controlled Industrial Area (CIA)?"

Would this specific designation only apply to the controlled areas at Norfolk Naval Shipyard, Pearl Harbor Naval Shipyard, Portsmouth Naval Shipyard, and Puget Sound Naval Shipyard? Would the secure area at Huntington Ingalls Industries in Newport News or other similar secure facilities be considered comparable?

The CIA is defined by the area inside the red line on the attachment :"NNSY Map.pdf".

Yes this area requires a second level of clearance as defined by specification 01 14 00.00 22- Work Restrictions, and other guidance.

125 CS and CU Sheets

There are several locations where the CS100 series sheets and the CU100 series sheets do not correlate. The CS100 series shows some existing utilities crossing through the cutoff wall or below the cutoff wall referencing a detail for casing to be installed, but no casing is shown to be installed on the utility on the CU100 series sheets with the note 5 callout..

Examples on the CS100 sheets include CATV at 0+20 (CS101), 8" storm at 14+60 (CS104), 4" sewer at 17+00 (CS104) etc....Please advise which drawings should govern in determining the utilities that require a casing to be installed.
