(Questions that may be of general interest to all Offerors and/or the Government and that are not readily answered by the proceeding changes will appear below. These questions may have been paraphrased or altered to represent several questions regarding the same subject and/or simply revised to clarify and simplify the question(s).

Questions and answers are issued to the Offerors “for information only ”and do not revise the solicitation, plans or specifications.).

Question 1: In Amendment 2, a requirement to purchase wetlands mitigation credits was included in the proposal and specifications. When contacting the approved bank, I was told that the price they provide is subject to change if a purchase agreement isn’t executed within 45 days.

As it is unclear what the duration will be prior to award, I ask that these items be converted to allowances rather than firm fixed price items.

Answer 1: Mitigation credit shall remain FIXED PRICE. Should the actual cost of the credits exceed the price quoted during bidding, the contractor may submit a request for an equitable adjustment for the cost difference. The contractor must be able to demonstrate through documentation that the quote received during the bid process was lower than the actual purchase price.

Question 2: Bid items 0002, 0019AB, 0019AJ, 0020AB, and 0020AK (the Floodwall and Culvert items) all include excavation and backfill as part of the scope of work. Where is the cost for the disposal of excess satisfactory material to be paid?

Answer 2: Excavated material is only to be hauled from the site if it is unusable for the rest of construction. If hauled from the site, cost will be paid under Bid Item 0011.

Question 3: In Amendment 2 the description for item 0011 Haul and Dispose states, "not including any work in Bid Item 0009." Is the reference to item 0009 correct? Should it instead be item 0020 (18AA)?

Answer 3: The reference to Bid Item 0009 should be to Bid Item 0014.

Question 4: There is over excavation and soil replacement shown on plan pages CG-104 and CG-105 and cross sections C-305 and C-306. This is mostly within the Option 1 limits of construction. Please confirm that the over excavation in this area is incidental Bid Item 0019AB and that the hauling and disposal of the over-excavated material for both the Base Bid and Option 1 is paid under item 0011 or 0014 depending on the characterization of the material and that the replacement soil is paid under item 0012.

Answer 4: Note that the majority of this material is required to be excavated for installation of the floodwall. Excavation and fill is incidental to floodwall Bid Item 0019AB. The excavated material is only to be hauled from the site if it is unusable for the rest of construction. If hauled from the site, cost will be paid under Bid Items 0011 or 0014 depending on characterization.

Question 5: With regard to the Base Bid Work versus the Optional Work, please clarify the following:

a. Please clarify why the entire C2 Flood Wall is not to be included in the Base Contract Price, and why certain sections of the C2 Flood Wall are bid as Optional Work.

b. Please clarify why it may take the Government up to 395 Calendar Days at NTP to determine if Option #1or Option #2 will be awarded?

c. Is it possible that Option #1 could be awarded without Option #2, or vice versa?

d. Is the entire C2 Flood Wall Project entirely funded by the Government for the Base Bid and Optional?

Work areas?

e. Are all Construction Easements and Rights‐of‐Way secured for this project?

Answer 5: The project is divided among a base and two options due to real estate acquisition.

All real estate in the base contract will be available by contract award; real estate in options1 and 2 is not yet acquired but is expected to be available within the 395 day period listed. In addition, the base contract is currently funded. Funding for options 1 and 2 is expected within the 395 day period listed.

Question 6: Please clarify if there is a cut‐off date for all questions to be submitted by the bidders

Answer 6: The cut-off date for all questions is COB 09/17/18.

Question 7: With regard to the Sheet Pile Cut‐Off Wall, please clarify the following:

a. The Sheet Pile structural Notes on Dwg S‐101, as well as the Sheet Pile Specification Section 31 41 16, appear to be providing a choice that allows the Contractor to select either Vinyl Sheet Piles, FRP Sheet Piles, or Steel Sheet Piles for the construction of the Cut‐Off Wall. Is this interpretation correct?

b. If the above interpretation is correct, please clarify why this highly unusual approach is being used for this project.

c. If all three Sheet Pile products are allowed to be used, then does the Government believe that all three Sheet Pile products are equal in their strength and performance?

d. In our experience, Vinyl Sheet Piles or FRP Sheet Piles are typically used in areas with relatively soft, unconsolidated sandy soils such as along the New Jersey coastal areas. Why does the Government believe that Vinyl Sheet Piles or FRP Sheet Piles are appropriate for the Green Brook project which requires the Sheet Piles to be driven to refusal into the weathered shale?

e. Considering the driving conditions on the Green Brook C2 Project, wouldn’t it make more sense to specify Steel Sheet Piles as the only reliable material to be used for the Cut‐Off Wall?

Answer 7: Amendment 2 eliminates vinyl and FRP sheet pile and requires steel

Question 8: Please clarify the apparent inconsistent use of “ highly weather shale” versus “weathered shale” in the notes on the drawings that apply to the Sheet Pile Cut‐Off Wall Refusal.

Note #5 on Dwg S‐805 uses the term “highly weathered shale” to define the Sheet Pile Cut‐Off Wall Refusal. However, Note #4 on Dwg S‐103 to S‐114 appears to use “weathered shale” to define the Sheet Pile Cut‐Off Wall Refusal. Yet, the Boring Logs use the following terms to classify the shale on this project: Decomposed Shale, Decomposed & Highly Weathered Shale, Highly Weathered & Decomposed & Shale, and Highly Weathered Shale. Since the Boring Logs do not differentiate between Weathered Shale and Highly Weathered Shale, please clarify which layer of Shale correctly defines the Sheet Pile Cut‐Off Wall Refusal.

Answer 8: The terms "weathered shale" and "highly weathered shale" are used synonymously on the drawings. There are two lines that pertain to sheet pile installation on the drawings. The lower of the two lines, labeled "Top of Weathered Shale and PZ22 Sheet Pile Tip Elevation" is the minimum depth to which the sheets must be driven for seepage considerations. The line labeled "SPT Refusal" has been included to indicate at what elevation additional driving effort may be required to reach the required tip elevation. See spec section 31 41 16 Sheet Piling, paragraph 3.2.2.2.f. In the event that a sheet reaches the required tip elevation but does not refuse, driving shall then continue until refusal.

Question 9: Please clarify how the Contractor is to determine the depths of the Sheet Pile Cut‐ Off Wall, for bidding purposes and in the field. For example, Note #4 on Dwg’s S‐103 to S‐114 states that the Sheet Pile Cut‐Off Wall is to be embedded some undefined distance into the Weathered Shale to Refusal. However, other Notes on the same drawings point to a dashed line below the footing on the Wall C2 Profile and indicate that the dashed lines represents the Top of Highly Weathered Shale and the Tip of the Vinyl Sheet Pile Cut‐Off Wall, which implies that the Sheet Pile Cut‐Off will not be embedded into the Weathered Shale. Since the Notes are not consistent, please clarify the expected depth of the Sheet Pile Cut‐Off Wall

Answer 9: The terms "weathered shale" and "highly weathered shale" are used synonymously on the drawings. There are two lines that pertain to sheet pile installation on the drawings. The lower of the two lines, labeled "Top of Weathered Shale and PZ22 Sheet Pile Tip Elevation" is the minimum depth to which the sheets must be driven for seepage considerations. The line labeled "SPT Refusal" has been included to indicate at what elevation additional driving effort may be required to reach the required tip elevation. See spec section 31 41 16 Sheet Piling, paragraph 3.2.2.2.f. In the event that a sheet reaches the required tip elevation but does not refuse, driving shall then continue until refusal.

Question 10: Please clarify how Vinyl Sheet Piles or FRP Sheet Piles can be driven into the Weathered Shale or Highly Weathered Shale without damaging these types of Sheet Piles.

Answer 10: Vinyl and FRP sheet piling have been eliminated by Amendment 2.

Question 11: Please clarify the method to be used by the Contractor to determine when the Cut‐ Off Wall Sheet Piles hit Refusal.

Answer 11: See Amendment 2, spec section 31 41 16 - Sheet Piling, paragraph 3.2.2.2.e

Question 12: Currently, Note #5 on Dwg S‐805, as well as Note #4 on Dwg S‐103 to S‐114, instruct the Contractor to use an Alternate Cast‐In Place Concrete Cut‐off Wall in lieu of the Sheet Pile Wall when the depth from the bottom of Pile Cap to the Top of Weathered Shale is 4’‐ 0” of less. Since the Boring Logs do not define any of the Shale Layers as “Weathered Shale” please revise the language in these Notes to be consistent with the Shale Classification terms used on the Boring Logs.

Answer 12: Based on the exploratory borings, the tip elevations for sheet pile are more than 4' below the bottom of pile cap, thus the alternate cut-off wall detail is not expected to be used.

The detail is included to cover the possibility that actual subsurface strata deviate from what was found during exploratory boring.

Question 13: We do not understand why the C2 Wall Profile Drawings do not indicate the areas of the project where the Alternate Cast‐In‐Place Cut‐Off Wall is to be used based on the Boring Logs. This type of design preference or choice can be shown on the drawings and should not be determined in the field, since that approach is relying on a “trial & error” approach. For example, Dwg S‐104 & S‐105 clearly show areas where the Top of Highly Weathered Shale is 4 feet or less from the bottom of footing. Yet, the plan view of the C2 Wall on these same drawings shows the sheet pile symbol and the notes indicate that Vinyl Sheet Piles are to be used in these same areas where the Alternate Cut‐Off Wall should be used. Therefore, we request that the Profile Drawings be revised to clearly show where the Sheet Piles are to be used and where the Alternate Cut‐Off Wall is to be used.

Answer 13: Based on the exploratory borings, the tip elevations for sheet pile are more than 4' below the bottom of pile cap, thus the alternate cut-off wall detail is not expected to be used.

The detail is included to cover the possibility that actual subsurface strata deviate from what was found during exploratory boring.

Question 14: On several of the C2 Profile Dwg’s S‐103 to S‐114 there are two dashed lines shown below the bottom of the footing. One dashed line is identified as “SPT Refusal”, and the other dashed line is identified as the Top of Highly Weathered Shale and Tip Elevation of the Vinyl Sheet Pile Cut‐Off Wall. On some Profile Views these two dashed lines converge, while other Profile Drawings show a variable depth between the two dashed lines. With regard to these two dashed lines, please clarify the following.

a. We do not find the term “SPT Refusal” shown on any of the Boring Logs and we see Blow Counts shown at all depths. Please clarify why SPT Refusal is not shown on the Boring Logs.

b. Please clarify what soil layer or soil condition is defined by the dashed line defined as “SPT Refusal”.

c. What is the relationship between the two dashed lines

d. Why isn’t there a more constant depth between the two dashed lines?

Answer 14: SPT Refusal is defined as 50 or more blows advancing less than 6". The geotechnical report uses the term to highlight the refusal elevation. Those elevations determine the lines shown on the drawings. See revised spec 3.2.2.2 Driving

Question 15: There are too many micropile bid items. The work cannot be broken down into as much detail as they are requesting as many of the items overlap. For example, casing is installed as you are drilling, we cannot offer two separate pay items that both include the associated labor equipment and material. Can you submit an RFI and propose that the Micropile Pay Items are changed so that there are only two items: (1) LF of fully installed permanently cased portion of pile and (2) LF of fully installed Rock Socket/Bond Length portion of pile which should also include temporarily casing the hole if needed?

Answer 15: Micropile bid items remains. The intent is to allow the USACE to have unit prices for all the components of the pile installation operation in the event that unknown subsurface conditions are found during construction and a change order becomes necessary. The unit prices will be in the contract.

Question 16: Contract Drawing EC-104 indicates a 'potential contractor staging and stockpile' area in the vicinity of Block 244, Lot 9. This area is partially located within the limits of the base bid and partially with the limits of option #1 for this contract. As the Corps may take up to 395 calendar days to choose to award Option #1 or not, the contractor's staging area has the potential to be severely limited throughout the bulk, if not the entirety, of the contract duration.

Furthermore, there is a house on the property and those are to be demolished under a separate contract, possibly further limiting our timely access to this area. Is another staging area available within the base bid project limits or in the surrounding area?

Answer 16: The houses are being demolished by change order to the current Segment B3 construction contract. Houses will be gone by January 1, 2019. There is not another staging area available within the base bid project limits or in the surrounding area. The Contractors are of course free to obtain their own staging areas.

Question: 17: We cannot find a Bid Bond Form in the Contract Booklet, and we could not find Section 00 70 00 – Contract Clauses that was referenced in the Bid Guarantee clause of Section 00 73 00 of the Special Contract Requirements. Please clarify if there is a Government Bid Bond Form that is to accompany the bidder’s proposal.

Answer 17: Bid bond form shall be on a SF24 (REV. 08/2016)

Question 18 a.

With regard to the Sampling and Environmental/Chemical Testing of Imported Soil specified in Section 2.1 of the Earthwork Specification Section 31 00 00, please clarify the following:

a. The first sentence describes a series of chemical tests that are to be performed by the Contractor for the approval of Offsite Soils. Please clarify if this Testing complies with all of the requirements established by the NJDEP for Residential Direct Contact Clean Soil.

Answer 18 a.

This is the Contractor's responsibility.

Question 18 b.

b. The second to last sentence states that at least one composite sample is to be tested from each Borrow Site. Please clarify if this is the only testing that is to be performed by the Contractor on the Borrow Soil.

Answer 18 b.

The Contractor shall perform comply with all state requirements for testing.

Question 18 c.

c. Please clarify whether or not periodic Sampling and Environmental/Chemical Testing will need to be performed on the Borrow Soil as the Borrow Soil is being imported and used at the site, and clarify which party is responsible for this testing, if requiredv

Answer 18 c.

One test per borrow site, indicative of all materials to be imported from that site, is required. The Contractor is responsible for testing and submitting test reports to the Contracting Officer.

Question 19

The first sentence of Part 3.15 of the Earthwork Specification Section 31 00 00 conflicts with Part 3.2.3 of the Seeding Specification 32 92 19 regarding the required preparation depth of the compacted subgrade. Section 31 00 00 says 2” deep and Section 32 92 19 requires 12” deep. Please clarify which specification section governs.

Answer 19

Specs added in amendment 2

Question 20

Based on the information collected during Government’s Subsurface Exploration Program, please clarify whether or not the excavated soils from the project site are expected (for bidding purposes) to be suitable for the backfilling of the new Flood Wall, Culvert C1, and other items, especially considering that the backfill will be used only for the support of landscaped areas.

Answer 20

Satisfactory material for general backfilling (non-structural, non-embankment) is defined in specification section 31 00 00 Earthwork, paragraph 1.2.1. The boring logs in the drawing set indicate types of soils expected to be encountered. It is expected that some of the excavated material will be satisfactory though it must be segregated from unsuitable material. The Contractor shall sample and test material intended for backfilling in accordance with paragraph 3.16 Testing to determine that it is satisfactory.

Question 21

Specification Section 09 97 02 requires the painting/coating of the Steel Micro Pile Casings as well as Steel Sheet Piles that may be used for the Cut-Off Wall. The coating of these two items is unnecessary and increases the cost of the project without benefit to the project. Once installed, these two items will be completely buried. Typically we do not see Micro Pile Casings provided with a protective coating, and the same observation applies to typical Sheet Pile Cut-Off Walls. In addition, the coating is likely to be damaged during the installation of both items, which negates any potential benefit of providing the coatings. Therefore, we request a revision to the Specifications that deletes the coatings for the Micro Pile Casings and Steel Sheet Pile Cut-Off Walls.

Please clarify.

Answer 21

No. Specs shall remain as written

Question 22

Dwg C-104 & C-105 indicate that an area adjacent to the proposed flood wall is to be overexcavated and backfilled with Embankment Material as per Spec Section 31 00 00 from STA 41+50 to STA 45+00. With regard to this area, please clarify the following.00 is to

a. Please explain why this area is to be over-excavated and backfilled with Embankment Material.

b. Please clarify why this area is to be treated differently from all of the other areas within the project limits.

c. Specification Section 31 00 00 does not have specific section that is called Embankment Material. Please clarify the type of material that is to be used for the backfilling of this area.

Answer 22

A and B are design requirements, See section 31 00 00 - Earthwork, paragraph 1.2.6 – Embankment Material

Question 23

We assume that the purpose of CLIN #0003 is to pay for the Off-Site Removal and Disposal of Unsatisfactory Soil that is geotechnically unsuitable, but not contaminated.

However, the description of work under this CLIN does not explicitly state this important bid condition, which creates an unnecessary contractual ambiguity that needs to be corrected prior to the bid date. Therefore, in order to correct this problem, please insert the word “uncontaminated,” in the first line, just before the word “unsatisfactory”.

Answer 23

The bidder has correctly interpreted the bid items. The term "unsatisfactory" is defined in the Earthwork spec and is sufficient.

Question 24

The description of work under CLIN #0004 does not clearly define what is intended by the statement that Borrow Material must meet “all residential requirements”. In other words, what residential requirements are to be met? We assume the intent is to require “Residential Clean Soil” to be used for all Borrow Material. However, this ambiguity needs to be clarified. Therefore, please revise the description of work under CLIN #0004 to make it perfectly clear that the Borrow Material must meet the specific requirements established by the NJDEP for New Jersey Residential Direct Contact Soil Clean-Up Criteria (NJAC 7:26D) as established by the NJDEP. Please clarify.

Answer 24

The bidder’s interpretation is correct.

Question 25

Please clarify under what circumstances (how and when) the Contractor will be paid to import Top Soil to the site under CLIN #0005

Answer 25

The requirement is that the Contractor will strip and stockpile existing top soil for reuse.

Top soil will only be imported when the stockpile is exhausted.

Question 26

With regard to the description of work for CLIN #0006, please clarify the following:

a. The description of work for CLIN #0006 does not mention Sampling and Testing, which needs to be done by someone in order to characterize the soil as being ID-27.

Please clarify this issue.

b. Please clarify how the ID-27 Contaminated Soil will be identified on this project for Off- Site Removal and Disposal.

c. Is it the intent to have all excavated soil Sampled and Tested before the excavated soil is re-used as backfill?

d. Since Sampling and Testing Services can get very expensive, and since it is not known at this time the extent to which the existing soils will need to be sampled and tested, we recommend that a new CLIN be inserted into the price proposal to provide a Fixed Allowance to cover the Sampling and Testing costs that may be required to characterize the excavated soils.

e. Has the Government performed any sampling and testing of the existing soils to determine if there may be any contamination in the soil?

Answer 26 The Government has sampled and tested soils in the general area and not found contamination. However, this sampling does not guarantee that there is no ID27 material. It is the Contractor's responsibility to sample and test soil to be transported offsite and to include the cost in the bid item.

Question 27

We found Temporary Sheet Pile Cofferdams on the two of the Erosion Control Drawings EC- 101 and EC104. No other drawings indicate the need for Cofferdams. This can be interpreted by bidders to mean that the contract only requires Temporary Cofferdams at those locations. Is this correct? Please clarify the Temporary Cofferdam requirements for bidding purposes.

Answer 27

The temporary cofferdams shown on the Erosion Control drawings are a condition of the Soil Erosion and Sediment Control Certification to be issued by the Freehold Soil Conservation District for this project. The Contractor’s means and methods of construction may require other temporary cofferdams.

Question 28

With regard to the Demolition and Removal (Site Clearing) work to be performed by others, vplease clarify the following:

a. Please confirm that all tree stumps will be removed and backfilled by the other Site

Clearing Contractor.

b. Please confirm that basements will be completely removed, backfilled and graded with imported fill material by the other Site Clearing Contractor.

c. Please confirm that all disturbed areas will be temporarily seeded and mulched to control soil erosion by the other Site Clearing Contractor.

Answer 28

All Confirmed

Question 29

Please clarify the responsibility of the Contractor and the Government with regard to the topsoiled and seeded areas that are located within the Flood Plain areas because these areas are at high risk of being damaged by flooding after these areas are seeded by the Contractor. The Government needs to recognize the special nature of this work. By the time the Flood Plain seeding work is performed these areas cannot be protected with temporary cofferdams, which means that the Contractor is completely at the mercy of the river. This means that recently seeded Flood Plain areas could be completely obliterated by flood waters, and this could happen multiple times, depending on when the Base Bid work is performed and when the Optional Work areas will be awarded. In the event that this type of flood damage occurs, please clarify what actions will be taken by the Government to make the Contractor whole. The bidders need to know if the Contractor will be compensated for replacing lost topsoil and for re-seeding the flood damaged Flood Plain areas.

Answer 29 The risk associated with damage to top soil, seed and plants shall be assumed by the Contractor. Please see specification section 32 92 19, paragraph 1.7.5: “Under the terms and conditions of the one-year plant guarantee – seeding, the Contractor shall be solely responsible for plant survival in seeded areas. Losses attributed to herbivores, disease, biodegradation, inappropriate hydrologic regimes, drought, insect damage, fire, wind or wave energies, ice scouring or vandalism shall not lower the minimum survival or coverage requirements.” Reference drawing VH601 includes a 20-year record of river discharges and stages to assist the bidders in assessing risk to build into their bids. Please note that the rating curve on drawing VH601 gives river stages in the NGVD datum while the project drawings use the NAVD88 datum.

Question 30 a.

With regard to the Painting of the Flood Wall, please clarify the following items in the Painting Specification Section 09 97 02.

a. A review of the Painting Specification Sections 1.3.1.4, 1.3.1.5, 1.3.1.6, 1.3.1.7, 1.3.2, indicates that this is a generic specification that applies to primarily to painting that is performed in a confined space within an enclosed building, such as a Paint Shop, and is primarily focused on painting metal surfaces. Therefore, please revise, remove or clarify the numerous conflicting requirements in the Painting Specifications that are not applicable to the Painting of the Flood Wall, which is not metal and will not be performed in a Paint Shop. These revisions are needed to avoid unnecessary confusion during the bidding phase of this project as well as during the construction phase of this project.

Answer 30 a.

Please be aware that the sheet piling – which is now required to be steel as part of Amendment 2 – and the micropile casings are to be coated with coal tar epoxy which is assumed to happen in an enclosed environment. The specification paragraphs cited in the question apply to painting of these items and not to painting of the floodwall.

Question 30 b.

b. Please clarify the intent of Painting Section 1.5.1 which requires the submittal of the “certificate for each Certified EHS Professional” who will provide “preconstruction and on-site environmental, safety and health services”. This section does not appear to pertain to the Painting of the Flood Wall. Please either remove Section 1.5.1 or provide clarification regarding the relevance of Section 1.5.1 to the Painting Specifications.

Answer 30 b.

The requirement is applicable to both shop painting of steel and painting of the floodwall.

Question 30 c.

c. Section 3.5 is either organized incorrectly or it is missing words, which is making it difficult to interpret with any certainty. Please review and clarify the reason why the alphabetical listing under Section 3.5 includes the following: (a) Steel Micropile Pipe Casings, (b) Steel Sheet Piles, and then (a) Floodwall.

Answer 30 c.

Please read the spec section carefully. The micropile casings and steel sheet pile are items a and b respectively in paint System 6 (coal tar epoxy); the floodwall is item a – the only item – under paint System 25 (concrete coating system).

Question 30 d.

d. The coatings that are specified in Section 3.5 for the Flood Wall only specify products produced by Euclid Chemical. However, there should be other coating manufacturers that produce coating products that are considered equal to the specified Euclid Chemical coatings. Please provide additional coating suppliers and coating products that are considered “Equal”.

Answer 30 d.

Please see revised spec section 2.2.2 Concrete Floodwall Paint. This specification is the only coatings approved for use on this project. They match the colors and coating characteristics of floodwalls previously constructed and to be constructed in the future on the Green Brook project.

Question 31

Please clarify the size of the portion of Culvert C1 that is to be constructed in Option #2.

Due to some conflicting details and notes, we are not certain if the Culvert in Option #2 is to be 6’ x 2.5’ or 6’ x 3’, or both.

Answer 31

Please see drawing S-113, the Plan – Grate Inlet C1-2 on S-701 and Section E on S-

702. These make clear that the inside height of the culvert increases from 2’-6” to 3’-0” very near to inlet C1-2 which is well within the limits of Contract Option 2. Therefore, the culvert is both 2’-6” high and 3’-0” high within the limits of Contract Option 2. This is also apparent on drawing C-201. (Please notice that the culvert profile on C-201 is drawn in reverse direction to the civil and structural plan views – the upstream or higher elevation of the culvert invert is on the left on C-201 but on the right side of the civil and structural plan drawings.)

Please note the plans, specifications and bid schedule are finalized Bids are due no later than 21 September at 2:00 P.M EST.
