BIDDER’S QUESTIONS AND GOVERNMENT REPLY

(Questions that may be of general interest to all Bidders 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 bidders “For Information Only” and do not revise the solicitation, plans or specifications.)

Bidder Inquiry 01: Please direct bidders to the contract plans, specifications, bid schedule, and other relevant bid documents.

Government Response: All documents including the Plans, Specs, and requirements and instructions for bidding, can be found at the System for Award Management (SAM) website at www.sam.gov using Solicitation W912DS24B0002 under “Attachments/Links”. The Plans are labeled “Part A, Part B, Part C and Part D”.

Bidder Inquiry 02: Can you please share any CAD files associated with the project plans, as well as any survey data?

Government Response: CAD Files are not available for public release. Project Survey Data can be found in “Part+A_Plans_SSSI_Area+E_General+Survey+Geotech_Dec+2023.pdf” as posted under the “Attachments/Links” section of this solicitation.

Bidder Inquiry 03: It is requested that the bid date be extended from it’s current bid opening date of February 1, 2024.

Government Response: Amendment 1 extended the bid date to 29 February 2024.

Bidder Inquiry 04: Is this an RFP/ Best Value contract?

Government Response: The solicitation is an Invitation for Bids (IFB), and the bid opening date is scheduled for 29 February 2024.

Bidder Inquiry 05: It’s assumed that the Pipe infrastructure in the streets is to be supported by piles such as CFA’s or Timber Piles. It’s not clear where the pile supports are to be installed and what pipe they are supporting. We are asking for a specific Bid item for the piles that show the total length and also clarity on what pipe they are to support.

Government Response: For pile supports information, refer to structural drawings: S-102, S-104, S-107, S-110, S-112, S-115, S-119, S-120, S-121 & S-122.

Bidder Inquiry 06: Will there be a Prebid and or a Site Visit for this contract?

Government Response: No pre-bid site visit will be hosted by the Government for this solicitation;

however, the entire project area is visible from public property. Contractors are encouraged to view the site at their own availability to aid in the development of their bids.

Bidder Inquiry 07: Sheet LP601 of the Landscape Plans requires some clarification. For example, it has two Wetland Emergent Zone plug charts with the same exact label but different plug mixes. Both are labeled with the same target elevations, yet they both have different quantities of the same species. Which is correct?

Government Response: There are three sets of landscape schedules on LP-601 that are specific to each BMP: BMP SBE-1A, BMP SBE-1B, and BMP SBE-1C. Each Wetland Emergent Zone plug schedule is specific to the BMP indicated (e.g. BMP SBE-1A requires 97,250 wetland emergent zone plugs, BMP SBE-1B requires 89,300 wetland emergent zone plugs, and BMP SBE-1C requires 8,650 wetland emergent zone plugs).

Bidder Inquiry 08: Sheet LP601, the chart for extended detention zone seed mixes appears to be duplicated, with the only difference being the elevation contour is 3.59 on one and 3.5 on the other. What is the intent with these two charts?

Government Response: There are two sets of extended detention zone seed mixes on LP-601 that are specific to BMP SBE-1A and BMP SBE-1B. Each extended detention zone seed mix schedule and elevation note is specific to the BMP indicated (e.g. BMP SBE-1A requires extended detention zone seed mix to be planted between el. -0.66 and 3.59, BMP SBE-1B requires extended detention zone seed mix to be planted between el. -0.66 and 3.5. BMP SBE-1C does not contain an extended detention zone so there is no extended detention zone seed mix specified. Please note, the correct upper elevation of the extended detention seed mix for BMP SBE-1B is 3.59. This has been adjusted on LP601.

Bidder Inquiry 09: Sheet LP601, Upland Zone Seed Mix. There are two identical charts with no distinction. What is the intent here?

Government Response: There are three sets of landscape schedules on LP-601 that are specific to each BMP: BMP SBE-1A, BMP SBE-1B, and BMP SBE-1C. While the Upland Zone Seed Mix schedules are identical, they are to be applied to each BMP as indicated.

Bidder Inquiry 10: Sheet LP601, Note 5, what is the purpose of providing the note saying "Shrub plants to be installed at 25% of acreage in upland zone"? Exact quantities of shrubs are provided, so how is the 25% to be used?

Government Response: The inquiry is correct; the quantity of shrubs was calculated based on 25% of the upland acreage for BMP SBE-1A and SBE-1B, respectively. Provide the quantity of shrubs per the landscape schedule for the upland zone as indicated for BMP SBE-1A and SBE-1B. Layout of the shrubs shall be as indicated in Note 7.

Bidder Inquiry 11: Sheet LP601, Note 5, there is a note on the right hand side of the page states "Shrub plants to be installed at 50% of acreage in upland zone". This is a conflict with the other Note 5 on the same page stating 25%.

Which is correct, and how is this information to be used when exact quantities are given?

Government Response: The inquiry is correct; the quantity of shrubs was calculated based on 50% of the upland acreage for BMP SBE-1C. Provide the quantity of shrubs per the landscape schedule for the upland zone as indicated for BMP SBE-1C. Layout of the shrubs shall be as indicated in Note 7.

Bidder Inquiry 12: Sheet LP601, please clarify Note 11 on the Plant Schedule Notes.

Government Response: The seed mixes are to be applied in their respective planting zones prior to the installation of plant material. Extended detention seed mix is to be applied to both the extended detention and the emergent zones. Upland seed mix is to be applied in the upland zones as well as in areas where the restitution trees are planted as noted on the LP drawings.

Bidder Inquiry 13: Bid Items #30, 15’’ DIP & Bid Item #50, 18’’ DIP. Are these two pipes to be installed on piles?

Government Response: Bid Item #3 15" DIP & Bid Item #5 18" DIP are the total linear footage of multiple pipes and will not be installed on piles.

Bidder Inquiry 14: 18’’ ESVP that is shown on Plan G108, with details on CU111. Where are we to include the costs of this work? Which item should include the cost of this work?

Government Response: The cost of the 18" ESVP shown on CG108 and CU111 should be included in Bid Item #54 Vulcan Street - Storm Sewer.

Bidder Inquiry 15: Can the Contractor reuse the Excavated Materials from this project to fill excavations/trenches to grade? Or must the contractor import clean material for fill?

Government Response: Excavated material is assumed to be contaminated non-hazardous material until acceptably proven otherwise. Onsite source material can be reused if acceptable through appropriate inspection and testing. Refer to Specifications Section 02 61 13 Excavation and Handling of Contaminated Material.

Bidder Inquiry 16: In the solicitation package, the workforce participation goals for the minorities and females are only listed. In terms of minority subcontractors, what is the percentage goal?

Government Response: It is incumbent upon the offeror to provide subcontracting percentages that they feel that are achievable and will maximize Small Business Participation through their subcontracting activities. Responses should be provided in accordance with 52.219-9 Alt I Small Business Subcontracting

Plan (SEP 2023) Alternate I NOV 2016. Any socioeconomic category that the offeror does not feel they can meet should be justified.”

Bidder Inquiry 17: Spec. Section 00 21 13 Instructions to Bidders under Additional Instructions lists five (5) documents to be submitted as the bid proposal submission. Please confirm that these are the only documents that need to be submitted, and also confirm that we do not need to submit the entire 101-page Solicitation.

Government Response: Yes, these are the only documents that are required, the bidders do not need to submit the entire 101 page solicitation.

Bidder Inquiry 18: Spec Section 00 21 13 Instructions to Bidders states: “NOTICE REGARDING BID BONDS, PEFORMANCE BONDS, AND PAYMENT BONDS: The Standard Forms (SF24, SF25, and SF25A) for these bonds have been revised as of August 2016.
