ANSWER: Amendment 2 extended the deadline for questions.

23. QUESTION: Can the proposal due date be extended.

ANSWER: Amendment 2 extended the deadline for proposals.

24. QUESTION: We would like to better understand the timing limitation outlined in spec 01

14 12 If possible (there maybe reasons for the restriction we are unaware of) we believe the work on the culverts needs to be starting in March or April 1 of 2024 and finishing in April or even early May as its necessary to gain access to the spillway. The anticipated Notice to Proceed is 11-29-24, at that time submittals will began being created and sent to the Bureau for review, I fear with the holidays and possibility of some submittals being rejected on their first review that we may not be ready to start work February 1, 2025. I don’t see a problem with work on the upstream side of the spillway occurring between Sept 1, 2025 – March 31, 2026 – only the culverts/access road to the spillway.

ANSWER: Refer to revised Specification Section 01 14 12 Work Restrictions and Limitations and revised Section F.

25. QUESTION: Is the 24/7 continuous pumping only required until completion and approval of the culvert portion of the road construction?

ANSWER: Refer to Specification Section 02 70 10 – Removal and Control of Water.

26. QUESTION: Does this project require a Full-Time Superintendent, Quality Control Manager and a Safety Officer? Or can the select personnel fulfill multiple roles (i.e.

Superintendent “dual hatting” as Safety Officer)? Note: There will be a significant amount of QC testing performed during this project. In fact, {company name redacted} envisions a representative of the independent testing agency being onsite daily throughout construction.

As a possible cost savings measure, would BOR consider allowing the independent testing agency, in lieu of the contractor, to function as the QC Manager, given their daily presence onsite?

ANSWER: No. Refer to Specification Section 01 46 00 Quality Procedures. The effectiveness of the Contractor’s Quality Control Program will be subject to continued review and approval by the CO.

27. QUESTION: Can water from Harry Strunk Lake be used in and for hydro/water cutting and saw cutting activities?

ANSWER: Yes, provided it meets the water quality standards required of the equipment used.

ANSWER: Refer to Specification Section 01 74 00 Cleaning and Waste Management paragraph 3.03.

30. QUESTION: There is no way to accurately estimate the amount of rebar replacement that will be required. If rebar/reinforcement is encountered that is rusted, degraded, or not at the stated depth of 3”, is there a CLIN to address rebar replacement on a unit-based quantity? Will the Government QC be on-site to determine if reinforcement is acceptable or determine and approve new rebar replacement? if rebar replacement is required, please provide a repair detail drawing for various scenarios.

ANSWER: Refer to Specification Sections 03 20 00 Concrete Reinforcing, 03 81 10 Concrete Removal and Drawing 40-D-60004.

31. QUESTION: The Government indicated that full-time or part-time onsite QC oversight will occur. Will the COR we able to approve “field adjustments” and “rebar replacement” on-site without delay or stop of work?

ANSWER: Yes.

32. QUESTION: If the contractor would reshape and grade the access road on the east side of the dam, to remove the extensive gulling, would it be allowable to utilize the road to bring materials in from that side of the spillway?

ANSWER: Yes. Refer Specification Section 01 14 00 Use of Site.

33. QUESTION: If a schedule can be developed and implemented to install the culvert area completely, could the remaining portion of the roadway be finished after the April 1 deadline?

ANSWER: Yes. Refer to revised Specification Section 01 14 12 Work Restrictions and Limitations.

34. QUESTION: Please provide the geology and/or reports that indicate the insitu soils and existing rock site conditions are adequate for road construction and soils and existing materials will proctor and compact in compliance with specifications.

Reactivity) test for the ready-mix aggregates mined locally, can admixtures be used to mitigate ASR?

ANSWER: No. Refer to Specification Section 03 30 00.

38. QUESTION: The Controlled Low Strength Material (CLSM) spec, 31 23 70, is not a pumpable material. Based on discussions with one particular supplier, the following mix is recommended to make it more pumpable: 50 lbs of type 1L, 250 lbs of C Ash and 10% air.

Would BOR accept this mix design as an allowable substitution?

ANSWER: Refer to Specification Section 31 23 70 Controlled Low Strength Material (CLSM), paragraph 2.05. The Contractor will be required to submit a mix design showing conformance with specified requirements for compressive strength and spread.

39. QUESTION: To facilitate installation of the culverts, will BOR be completely shutting off water released from the outlet works; or does the contractor need to construct a coffer dam, in conjunction with a pumping system, to pump water away from the work area of the culvert?

ANSWER: The outlet works will be closed during the non-irrigation season to allow installation of the culvert crossing. See revised Specification Section 01 14 12 – Work Restrictions and Limitations paragraph 1.02, B.

40. QUESTION: According to Section 01 57 30 (1.05.A.1.a): “The Bureau of Reclamation has made application for a permit to discharge dredged or fill material into waters of the United States (including wetlands) as required under section 404 of the Clean Water Act (Public Law 92-500 as amended.” What is the status of the 404 permits?

54. QUESTION: Section 01 31 19, Part 01.04.A.1.a.1 mentioned Project Engineer attendance.

Does this project require a full-time or part-time On-site Project Engineer? If yes, does he/she need to be employed by the Contractor?

ANSWER: There is not a requirement for a Project Engineer.

55. QUESTION: Section 01 35 30 – 4, Part 01.05.D talks about CIH requirement; However, D.1.b states that or as deemed necessary by the COR. Does this project have full time or part time On-Site CIH requirement? If yes, does he/she need to be employed by the Contractor?

ANSWER: Refer to revised Specification Section 01 35 20 Safety and Health paragraph 1.03, B, 8, r, 1, e.

56. QUESTION: Does any work need to be performed in the upstream face of spillway?

ANSWER: No. Refer to revised Specification Section 01 14 12 Work Restrictions and Limitations and revised Drawing 328-600-60077 in revised Specification Section 52 00 00 Drawings.

57. QUESTION: Does any sandblasting and coating need to be performed on this project?

ANSWER: There are no coatings to be performed. Sandblasting may be required as specified in Section 03 30 00 Cast-In-Place Concrete paragraph and revised drawing 328-600-60077.

58. QUESTION: Has the government performed any type of survey for existing contaminants?

On these solicitations, there are typically preliminary assessments/surveys for contaminants that provides the basis for all the environmental, industrial hygiene, and safety/health requirements listed in the project specifications. If a survey or assessment has been performed, can you please provide a copy of it? If a survey is not performed, please let us know the requirements of exposure assessments.

ANSWER: The Government has not performed surveys or testing for existing contaminants.

Exposure assessments are for engineering controls to mitigate exposures to hazardous substances or potential environmental impacts. (i.e. respirable silica, excessive noise, etc.) Refer to Specification Section 01 35 20 Safety and Health.

59. QUESTION: Can the contractor begin spillway repairs with pier 2 and 3 repairs then starting at Panels 1-7 and working from top to bottom? The specs say to complete panels 43

– 56 first but we believe the work will be more efficient and safe proceeding from top to bottom as the hydro demolition debris will always be rolling down to the stilling basin which will make it hazardous to begin performing concrete repairs below the robot.

Starting at panels 43-56 could create a need for the hydro demolition equipment to demobilize and remobilize while waiting for the lower concrete repairs to complete and cure prior to beginning removals at the top.

60. QUESTION: Per Page 379, Factor 2: Company Experience, provide at least three (3) past projects and the following information must be provided for each project:

• Key personnel directly involved in the projects. Provide resumes of key personnel from the projects for personnel currently employed by the offeror/subcontractor.

Please clarify if we submit a project that none of the key personnel remain on our current staff, that the project is still valid to be submitted for past performance. Typically, it is a requirement to provide resumes for planned staff for a proposed project.

ANSWER: Refer to revised Sections L & M removing the requirement for key personnel resumes and evaluations thereof.

61. QUESTION: Per Page 379, Factor 2: Company Experience, for consideration of projects for evaluation, could you please advise if it is acceptable to use the experience and qualifications sister companies and/or related subsidiaries under the same parent company for consideration for this proposal?

ANSWER: No.

62. QUESTION: There is a requirement for a part time Safety Professional in 01 35 30. How often does this individual need to come to the site?

ANSWER: See revised Specification Section 01 35 30 Contractor’s On-Site Safety Personnel.

63. QUESTION: 01 14 12 1.02.B.1 (Work Restrictions and Limitations) notes that work on the culverts will be limited to Sept 1st through March 31st. Will the Outlet Works Regulating Gate be closed at this time and that the only flow will be from leakage from the gate, and seepage from the toe-drain outfalls?

64. QUESTION: Can the Government provided an estimate of the amount of leakage for the

Outlet Works Regulating Gate?

ANSWER: Refer to revised Specification Section 02 70 10 Removal and Control of Water.

65. QUESTION: 31 02 10 – Water for dust abatement requires water to be applied twice a day during earthwork activities. Is there a water source that can be utilized from the lake or outlet works or does the contractor have to source water themselves?

ANSWER: Water from the reservoir may be used.

66. QUESTION: 02 70 10 3.02.A notes the requirement to remove any debris in the stilling basin. Does the Government expect there to be existing debris in the basin or does this note refer to debris from construction activities? If there is existing debris, does the Government have an idea as to how much debris that may require removal?

ANSWER: The stilling basin was un-watered and cleaned in 2017. The government expects little to no debris in the stilling basin. Refer to Specification Section 01 74 00 Cleaning and Waste Management.

ALTERNATE III (MAR 2022)

(a) General Security Requirements:

(1) This clause addresses security requirements, including general procedural requirements, information security requirements, contractor employee suitability requirements, identification card requirements, site security requirements, vessel exclusion barriers, and information technology security requirements. Within this clause, COR means Contracting Officer's Representative. If there is no COR appointed and identified to the Contractor, the term instead will mean the Program Manager or any other authorized individual responsible for technical oversight under the contract. “Work site” means the Government facility, office, construction site, and any other area within the Government office or facility that the Contractor must access to accomplish work under this contract.

(2) The work performed under this contract shall only be accomplished by individuals (in the employment of the Contractor or any subcontractors) whose conduct and behavior is consistent with the efficiency of the Federal Service and the requirements of this contract, and who are acceptable to the contracting officer. If Reclamation finds a Contractor employee to be unsuitable or unfit for his or her assigned duties, the contracting officer will direct the Contractor to remove the individual from the contract and access to the Federal facility at which the contract activities are occurring.

(3) The Contractor’s employees governed by this contract may need access to sensitive information and/or sensitive areas. The Federal Government (Government) reserves the right, in its sole discretion, to determine suitability of Contractor personnel and deny access to any sensitive information or project specific area to any personnel for any cause.

(4) The Contractor is responsible for informing and ensuring compliance by its employees with any applicable security procedures of the Government facility where work may be performed under this contract.

(5) Any Contractor employee that will have access to a Federally-controlled facility or information system will be required to have a Government-issued identification card, consisting of a Personal Identity Verification (PIV) Card, a temporary identification card, or a visitor badge.

(Note: within the Department of the Interior this card is known as a DOI Access Card.) During performance of the contract, the Contractor shall keep the COR apprised of any changes in personnel, or changes in personnel access or duration, to ensure that performance is not delayed by compliance with credentialing processes.

(6) A Contractor employee will not be provided access to a Government facility or information system until a Government PIV Card, temporary identification card, or visitor identification badge has been issued to the Contractor employee. For those individuals that will be receiving a PIV Card, the Government may, at its discretion, issue a temporary identification card or visitor identification badge after the electronic background investigation forms have been received and the investigation is initiated.

(7) All Contractor employees shall access the facility via the facility’s entry screening system and visibly display the Government-issued PIV Card, temporary identification card, or visitor identification badge at all times. Contractor employees must visibly wear the Government-issued identification card at all times they are on Government facilities. Contractor employees are responsible for the safekeeping of all Government-issued identification cards, whether on-site or off-site. Cards that have been lost, damaged, or stolen must be reported to the COR and DOI Access Sponsor immediately, but not later than within 24 hours. The Contractor shall return all identification cards and card keys and any other Government property and information upon completion of performance or when personnel depart permanently or for a period of 7 days or more. The Contractor may be required to turn in access control cards or identification cards on a daily basis.

(8) Misuse or loss of access control or identification cards, or failure to comply with required surrender of such cards may, at Government discretion, result in Contractor personnel being denied access to the work site, at no cost to Government. The Contractor may be charged up to $500 for each occurrence for any required replacement of Government-issued access control or identification cards due to loss or misuse. At the end of contract performance, or when a Contractor employee is no longer working under this contract, the Contractor shall ensure that all access control and identification cards are returned to the COR.

(9) All Contractor personnel, including subcontractor personnel, with access to the work site shall be U.S. citizens or foreign individuals legally residing in, or legally admitted to, the U.S. For all non-U.S. citizens working under this contract, irrespective of length of time working on the contract, the Contractor shall provide to the COR, legible and valid copies of the individual’s passport and visa (unless individual is on the Visa Waiver Program) a minimum of 14 calendar days prior to beginning work or arriving at the facility. A driver’s license is not acceptable identification. In addition, a completed form I-94 shall be submitted to the COR upon the individual’s arrival at the work facility and prior to beginning work.

(10) The Contractor shall report all contacts with entities, individuals, and counsel/representatives (including foreign entities and foreign nationals) who seek in any way to obtain unauthorized access to sensitive information or areas. The Contractor shall report any violations of contract provisions, laws, executive orders, regulations, and guidance to the contracting officer. The Contractor shall report any information raising a doubt as to whether an individual’s eligibility for continued employment or access to sensitive information is consistent with the interests of National Security and the Public Trust.

(11) Unsanctioned, negligent, or willful inappropriate action on the part of the Contractor (or its employees) may result in termination of the contract or removal of some Contractor employees from Reclamation facilities at no cost to the Government. These actions include, but are not limited to, exploration of a sensitive system and/or information, introduction of

I-22 unauthorized and/or malicious software, inappropriate release of sensitive information, or failure to follow prescribed access control policies and/or security procedures. Failure to comply with Reclamation policies, procedures, or other published security requirements may result in termination of the contract or removal of some contracted employees from Reclamation buildings and/or facilities at no cost to the Government.

(12) All provisions of this clause shall equally apply to all subcontractors. The Contractor shall incorporate the substance of this clause in all subcontracts.

(13) These security requirements apply to all sections of this Contract including Contract Drawings and other Contract Specifications as applicable. Related documents include other general provisions of Construction or Operations and Maintenance type Contracts, including FAR clauses by reference or as amended by related documents.

(b) Information Security Requirements.

(1) Sensitive Information. The term “sensitive information” means any information which warrants a degree of protection and administrative control as defined by Reclamation or that meets the criteria for exemption from public disclosure set forth under Sections 552 and 552a of Title 5, United States Code: the Freedom of Information Act and the Privacy Act. Sensitive information is generally categorized as CONTROLLED UNCLASSIFIED INFORMATION (CUI), but in some cases may include other unclassified information. (The protection of National Security information is beyond the scope of this clause. If any work on National Security information is required under this contract, it is addressed under other contract clauses.) The Contractor shall protect this type of information from unauthorized release into public domain, or to unauthorized persons, organizations, or subcontractors. Information which, either alone or in aggregate, is deemed sensitive by Reclamation shall be handled and protected in accordance with Reclamation Directives and Standards SLE 02-01 Identifying and Safeguarding Controlled Unclassified Information (CUI), which is available from the COR or at http://www.usbr.gov/recman/DandS.html#sle.

(i) Any Government-furnished information or material does not become the property of the Contractor and may be withdrawn at any time. Upon expiration or termination of the contract, all documents released to the Contractor and any material created using data from such documents shall be returned to the COR for final disposition. Government-furnished information residing on any electronic systems (laptops, servers, desktops, media) shall be deleted from those systems using a COR-approved data erasure solution. Only with prior authorization from the contracting officer may the Contractor retain the material. The Contractor or subcontractor shall not disclose or release the materials provided to the Contractor to any individuals of the Contractor's organization not directly engaged in providing services under the contract or that do not have a valid need-to-know. All technical data provided to the Contractor by the Government shall be protected from public or private disclosure in accordance with the markings printed on them. All other information relating to the items to be delivered or the services to be performed under this contract shall not be disclosed by any means without prior approval of the contracting officer. Prohibited dissemination or disclosure includes, but is not limited to: permitting access to such information by foreign nationals or by immigrant aliens who may be employed by the Contractor, publication of technical or scientific papers, advertising, disclosure to Contractor staff not investigated and deemed acceptable at the appropriate information sensitivity level, I-23 and any other public release. The Contractor shall maintain, and furnish upon request of the contracting officer, records of the names of individuals who have access to sensitive material in its custody and the sensitive material to which the individuals had access. All questions regarding information security, access, and control shall be referred to the COR.

(ii) The Contractor shall not release to anyone outside the Contractor’s organization any sensitive, or otherwise protected information, regardless of medium in which it is contained (for example, film, tape, document, electronic), pertaining to any part of this contract or any Reclamation program or activity, unless the contracting officer has given prior written approval. This includes, but is not limited to, news releases, marketing promotions, articles, interviews, reports, social media posts, and any other media releases. Requests for approval shall identify the specific information to be released, the medium to be used, the purpose for the release, and a description of the need-to-know. The Contractor shall submit its request to the contracting officer ten business days before the proposed date for release. Subcontractors shall submit requests for authorization to release through the prime Contractor to the contracting officer.

(iii) The Contractor shall notify the COR immediately when known or suspected loss/compromise of sensitive information or other documents, notes, drawings, sketches, reports, photographs, exposed film or similar information which may affect the security interests of Government has occurred. This requirement extends to employees and other personnel working on behalf of the Contractor, and expands responsibility to include prompt reporting of security issues, including observed or subsequently discovered efforts by unauthorized persons to gain unauthorized access to sensitive information.

(2) Classified Information.

(i) The disclosure of U.S. Government documents by third parties can result in damage to our national security. While this contract may not deal directly with classified information, each contractor is obligated to protect classified information pursuant to all applicable laws and to use Government information technology systems in accordance with agency procedures so that the integrity of such systems is not compromised.

(ii) Unauthorized disclosures of classified documents (whether in print, on a blog, or on websites, or other electronic or non-electronic media) do not alter the documents' classified status or automatically result in declassification of the documents.
