King piles BH115, BH67, BH55 and BH1 have single sheets perpindicular to the alignment of the proposed combiwall structure. The existing face of the MZ Sheet pile wall is shown to be 3'4" behind the centerline of the king piles per detail A1 on DWG SB503. The existing MZ Sheet Pile Wall includes a wale that will remain in place after partial demolition of the MZ Sheet Pile wall and appears to conflict with the transverse sheets to be installed at BH115, BH67, BH55 and BH1. Please confirm contractor is to remove/demo the wale at these locations to allow for the installation of the transverse sheet piles.

See A1/SB503, and yes wale must be cut to install closure. Note that closures will only be required at the ends (BH1 and BH115) since the pier is part of the base bid.

71 C-102

Soil Manage ment Note 4

Section 01 57 19

1. Reference Drawing C-102, Soil Management Plan Note 4 and Specification Section 01 57 19 (Introductory Paragraphs) which respectively require:

“For bidding purposes, assume 100% of excavated material will be contaminated.

Refer to Specification Section 01 57 19, Temporary Environmental Control and Section 02 61 13, Excavation and Handling of Contaminated Material. Attention is called to the characterization data on the nature and extent of the contaminated material included in 02 61 13, Attachment A.”

and “For bidding purposes, assume 100% of excavated material in these areas and all debris from in-water work will be contaminated.”

It does not appear as if the contract differentiates between “contaminated” and “hazardous” materials and it is our experience that while all hazardous material is considered contaminated, not all contaminated material is considered hazardous. As Drawing C-102 references bidders to specification section 02 61 13 Attachment A (which contains test results

Pursuant with Section 01 57 19 (Part I – General), assume 100% of excavated material will be contaminated as the waterfront/per landing areas are an Installation Restoration site. It is assumed at this time that excavated material will be nonhazardous for estimating purposes, which is consistent with the September 14, 2019 Tetra Tech ROD that states “Excavated soils will be managed as remedial action construction-derived waste, which will be characterized, transported, and disposed off-site appropriately based on the characteristics of the waste (assumed nonhazardous for estimation purposes)”. Pursuant with 01 57 19 (3.7.1.1 – Sampling and Analysis of Waste) and 02 61 13 (1.2 Description of Work) waste must be demonstrated to be nonhazardous through sampling and analysis. Work must be performed in compliance with all federal, state, or local controls for handling, storage, or disposal pursuant with 01 57 19 (1.2.13).

Also, recent construction activities may have resulted in a release of asbestos containing material (ACM) which for numerous hazardous materials on site), it could be construed that offerors must assume that all excavated materials and debris from in-water work is both contaminated and hazardous.

The costs and risks of the project are significantly impacted by the specific amounts, makeup, and concentrations of hazardous materials, it is not practicable for offerors to make such a broad assumption within their bid pricing. We request that the Government provide clarification distinguishing “contaminated” from “hazardous” materials as it relates to offerors’ required bid price assumptions.

requires an asbestos-contaminated land survey in areas with visible signs of potential asbestos debris (02 61 13 [1.2 – General]). However, at this time, there is no confirmed volumetric estimate for such material if it were encountered.

Price per Price Proposal Form Line Item 0014, Option Item 12.

72 02 81 00 1.4.4

2. Reference Specification 02 81 00, Paragraph 1.4.4 which notes (emphasis added):

“Comply with Federal, state, and local laws and regulations addressing transportation and management of hazardous materials including but not limited to DOT 4500.9R, OPNAVINST 4110.2, Rhode Island Department of State 250-RICR-140-10-1, and Rhode Island General Law 31-23-37.

These requirements are amended frequently and compliance with amendments is required as they become effective. Notify the Contracting Officer immediately if compliance exceeds the scope of work or conflicts with specific requirements of the contract.”

Any change in law contemplated by the above referenced specification section could significantly impact the cost and time of performance of the work. Although the contract notes that such changes may “[exceed] the scope of work” or “[conflict] with specific requirements of the contract”, there is no explicit statement that the contractor is entitled to an equitable adjustment for such a change. We request that the Government consider amending the above language to confirm that changes is law which impact the contractor’s cost or schedule will be addressed in accordance with FAR 52.243-4 Changes.

Changes in law which impact the contractor’s cost or schedule will be addressed in accordance with FAR 52.243-4 Changes.

73 01 57 19 3.7.3.1

3. Reference Specification 01 57 19, Paragraph 3.7.3.1:

“Hazardous waste generated within the confines of Government facilities is identified as being generated by the Government.”

and Specification Section 02 41 00, Paragraph 3.3.1 (Title to Materials):

“Except for salvaged items specified in related Sections, and for materials or equipment scheduled for salvage, all materials and equipment removed and not reused or salvaged, shall become the property of the Contractor and shall be removed from Government property. Title to materials resulting from demolition and deconstruction, and materials and equipment to be removed, is vested in the Contractor upon approval by the Contracting Officer of the Contractor's demolition, deconstruction, and removal procedures, and authorization by the Contracting Officer to begin demolition and deconstruction.”

Please consider revising Specification Section 02 41 00, Paragraph 3.3.1 to exclude hazardous waste from items which become the Contractor’s property and for which title is vested in the Contractor.

Section 02 41 00 is relevant for materials from the demolition of existing structures and utilities and this language would not change. While 02 41 00 (2.1 – Fill Material) does reference the requirement to comply with excavation, backfilling, and compacting of soils, this specification does not include excavated materials (e.g., soil/sediment) as Contractor property for which Section 01 57 19 and 02 61 13 applies. With regards to excavated material (e.g., soils), 01 57 19 Part 1 defers to Section 02 61 13 for the requirements to manage contaminated soil, and Section 02 61 13 (3.8) defers to Section 01 81 00 for the management of such materials that are found to be hazardous. In turn, Section 02 81 00 (3.2

– Onsite Hazardous Waste Management) states that the paragraphs apply to Government owned waste. This would include excavated materials (e.g., soil) for which 02 81 00 (3.3.4) requires the generator (Contracting Officer) sign hazardous waste manifests, not the Contractor.

74 02 81 00 3.2

4. Reference Specification Section 02 81 00, Paragraph 3.2:

“Comply with generator requirements in 40 CFR 262 when accumulating hazardous waste onsite.”

Please note that 40 CFR 262 contains certain requirements that can only be managed by the generator itself (generator category determination, annual reporting, etc.). Please consider revising the above to:

“For hazardous waste generated under this contract, comply with generator requirements in 40 CFR 262 on behalf of the Government when accumulating hazardous waste onsite.”

As related to construction-related hazardous waste generated by the Contractor, this request would not apply.

As related to the staging of excavated material that is determined to be hazardous, the staging, labeling as appropriate, storage, BMPs, and adherence with federal/state waste accumulation times, and as otherwise documented in the specifications, will be the responsibility of the Contractor.

However, 02 81 00 (3.2) also requires coordination with the installation environmental function and the Contracting Officer. Federal/state requirements (e.g., annual reporting) for the Department of the Navy based on the generator status of the installation are separate from the Contractor requirements under the specifications.

5.B.2

Process for determin ing whether subgrade is suitable

After reviewing the specifications, the description of Option 6, and the notes in the drawings we are seeking clarity on subgrade acceptance by the CO. Note 2 requires the contractor to notify the CO rep when loose or soft soils are exposed…. so that a determination may be made regarding the improvement of this potentially undersireable condition. If there were no other notes / specs then exercising Option 6

- undercutting and disposing of unsuitable subgrade material and replacement with Structural Fill would be the solution.

However, the specifications don't provide a clear path to subgrade acceptance:

3.3 - Excavation "Excavate to contours, elevation and dimensions indicated.", "Excavations below indicated depths will not be permitted except to remove unsatisfactory material. Unsatisfactory material encountered below the grades shown shall be removed as directed. Refill with satisfactory material and compact to 95% of ASTM D1557 maximum density."

3.3.6 - Final grade of surfaces to support concrete "Excavations to final grade shall be made until just before concrete is placed."

3.4 - Subgrade Prep "Unsatisfactory material in surfaces to receive fill or in excavated areas shall be removed and replaced with satisfactory materials as directed by the CO."

3.4.1 - Proof Rolling "After stripping proof roll the existing subgrade of building....Rutting or pumping of material shall be undercut as directed by the CO and replaced with select material."

All these sound alot like what is described above in Note 2 and Option 6.

Then you read specification 3.10 - Compaction "Determine in-place density of subgrade; if required density exist, no compaction of existing subgrade is required." and 3.10.2 - Structures, Spread Footings and Concrete Slabs "Compact top 12 inches of subgrade to 95% of ASTM D1557."

Did the criteria for subgrade acceptance just change? That if, the existing subgrade is tested and does not pass 95% compaction, then the contractor owns the effort of compacting the top 12 inches of subgrade?

This could include removing subgrade

The criteria for subgrade acceptance did not change, Section 3.10 Compaction is an additional requirement to prevent/minimize settling. Contractor is responsible for compacting the the subgrade, and removal of subgrade material for compaction may be required.

Contractor shall meet subgrade preperation and compaction requirements as specified. Sections 3.10 and 3.10.2 are applicable to all concrete structures.

Specifica tions Attachm ent

Specifications attachment final submittal document 1562331_spc_att_101 indicates in several locations throughout that asbestos is present in sediment, and while there is no current risk associated with asbestos in sediment, there may be potential future risk if the associated sediment were to be dredged and allowed to dry out. In summary our understanding is the response action will include safeguards to protect potential future receptors from this potential and that the navy determined that it would be appropriate to include a response action for asbestos in sediment to address the concern by developing documentation precautionary measures and safe work practices. Scenario (1): During the course of marine construction contractor will predrill the sheet pile for the bulkhead which is required by spec and introduce temporary materials such as pin piles into the sediments with periodic removal as a course of normal means and methods for marine construction. During removing the drill and temporary materials required for marine construction the potential for sediments with asbestos may be removed from water. Question (1): will the sediment removed from water need be contained, tested, and disposed of appropriately Please Clarify. Question (2): Where is the containment, handling, testing, and disposal of the sediments with potential asbestos paid for in Attachment H? Please clarify.

Question (3): Will government consider providing an allowance to include in the estimates for bidding purposes which is intended to capture the contractors costs associated with containing, handling, testing, and disposal of sediments with asbestos?

As indicated in 02 61 13 (1.2 – General), “…as relevant for Site 19/Operable Unit 12 (or other areas with visible signs of potential asbestos debris) …Asbestos-contaminated land surveys should be performed…”. Also, 01 57 19 (3.10 – Control and Management of ACM), the Contractor is required to “Manage and dispose of asbestos-containing waste in accordance with 40 CFR 61, Rhode Island Rules and regulations…and all federal, state, and local requirements."

While is has been reported that recent construction activities may have resulted in a release of asbestos containing material (ACM), at this time, there is no confirmed volumetric estimate for such material if it were encountered. This includes sediment that is within 0U5 (marine sediment) that is within ERP Site 19.

Attachm ent H Option 7

Attachment H - Option 7 pay item indicates underwater debris removal and disposal, in accordance with the drawings and specifications, for the bulkhead, for objects and debris larger than 0.25 cy. Question (1): If an obstruction is encountered which is assumed greater than 0.25 cy and cannot be removed by excavation and must be overcome by means of DTH Hammer, spudding, or other means to break the obstruction in order to advance the pile then how is the contractor paid for the additional level of effort, time, and materials associated with the DTH Hammer, Spudding, or other means required to advance the pile? Question (2): if an obstruction is encountered which is assumed greater than 0.25 cy and it is determined the most economical means for removal is by excavating the material then

See Amendment 0007, Upadted Attachment H-Price Proposal Form R4.

Option 7 is intended for debris removal that can be picked up with a clam shell or similar means, effort for use of DTH hammer will be be carried in the Obstruction Line item.

is the contractor paid for the excavated material in addition to the debris which is larger than 0.25 cy? Question (3): if an obstruction is encountered and removed via excavation and the excavated material is contaminated where is the handling, testing, and disposal of the contaminated material paid?

Attachm ent H Option 7

Attachment H - Option 7 pay item indicates to provide underwater debris removal and disposal, in accordance with drawings and specifications, for the bulkhead, for objects and debris larger than 0.25 cy encountered.

Question (1): Confirm this pay item is applicable to removal of obstruction and debris in water larger than 0.25 cy at all planned trestle and pier water side pile locations

Attachment H Option 7 is only for debris removal at the bulkhead effort on the pier and trestle if anticipated may be included under the line item for Obstructions.

104 General

Our understanding of the requirements for the sheet pile bulkhead installation are as follows: Contractor is to perform the indicator pile program to find top of glacial till. Contractor is to prob prior to installing sheets and contractor is to predrill to loosen soil but the diameter of the drill shall not exceed 8 inches and minimum center to center distance of the hole is 16". If an obstruction is encountered which is greater than 0.25 CY it is removed under Option 7 and paid for by the Unit Price per Ton.

Clarify the following: (1) if obstructions are found along the length of the wall such as rip rap under the sediments and a significant volume of sediment along the wall is required to be moved to expose the rip rap for removal where is the cost of moving the sediments paid? (2) if sediments require removal and disposal will government permit decanting the barge and reintroducing the decanted water into the waterway with follow on transloading of the sediments to land for testing, and appropriate disposal? (3) where is this work paid which includes the handling of sediments, decanting sediments, transloading sediments to land, testing, and follow on disposal?

The intent of Obstructions are for Bearing Piles and not king piles, which are covered onder the STEEL

FOUNDATION NOTES - STEEL

BEARING PILES. Also this project is not intended to be a dredging project, we do not anticipate sediment disposal.

Please confirm that pier fender piles (16" Pipe Pile) do not have an axial capacity requirement, and acceptance of fender piles relys on minimum tip elevation for lateral stability only.

PDAs are not indicated for Steel Fender Piles on Sheet SB603 therefore they must be driven to indicated minimum pile tip elevation to estabilish lateral stability.

Please confirm if the axial capacity requirement noted on drawing SB003 for 18" pipe piles also applies to the 18" combiwall king piles, or if the 18" combiwall king piles are only required to be driven to minimum tip elevation to establish lateral stability.

PDAs are not indicated for Bulkhead for King Piles, which are covered under

STEEL COMBINATION PIPE-Z

BULKHEAD. The correct response is that All of the steel piling in the Pipe-Z bulkhead must be driven to minimum tip elevation to estabilish lateral stability, as indicated on sheets SB601 and SB602.

Specification 31 62 16.13 Paragraph 3.2.8.1 states "…and the obstruction cannot be cleared by their drilling or spudding,…" with respect to obstructions encountered during pipe pile driving. Note 6 on Drawing SB003 under "FOUNDATION NOTES - STEEL PIPE PILES" states "Spudding and/or jetting of steel pipe piles will not be allowed." These appear to be contradictory, please confirm spudding of pipe pile will be allowed if an obstruction is encuontered.

See Amendment 0007, continuation page.

Spudding is permitted, Jetting is not.

Note 6 has been revised.

Clarify if past project with DBE goals versus SB goals can be used to complete Attachment E Historical Small Business Utilization form

No, Bid per RFP.

Specification 31 62 16.13 Paragraph 2.2.1.A.1 states Helical-lap seams are not permitted for steel pipe piles. Drawing SB002 states Steel Pipe Piles must conform to the following "ASTM A252, GRADE 3 MODIFIED FY=60 KSI". Please confirm spiral weld pipe pile are permitted.

Bid per RFP, please note that a spiral welded pipe pile is not a helical-lap seam pile, spiral welded piling is acceptable.

Specifica tion

01 57 19 3.3.1

Per Spec 01 57 19 3.3.1 “Discharge of ground water is prohibited. All ground water is to be collected into frac tanks and disposed of offsite in accordance with state regulations and specification 02 61 13”.

Spec 02 61 13 3.3.4 states to “Capture, sample, and dispose of dewatering effluent in accordance with all local, state, and federal laws. Due to the unknown qty of potential water disposal encountered during deeper utility installations, and the requirement for these liquids to be stored in 55 gal drums or 500 gallon tanks, please clarify if it is allowable to treat the groundwater on site to within the given laws and discharge/percolate on site.

Per the referenced specification, “Discharge of ground water is prohibited”. This does not allow for treatment and then discharge. However, Contractors have the option to perform treatment that may reduce disposal costs at their discretion. This is in part related to the ongoing Land Use Controls within Site 19 and the potential for treated groundwater from dewatering to become recontaminated if discharged/percolated on site.
