SUBJECT: Addendum 1 to 42303IFB26 – Pablo Creek Conservation Area Cultural

Resources Assessment Survey

As a result of questions received from potential respondents, please be advised of the following changes to the subject IFB:

Questions/Answers

Q1 May a firm submit a proposal as a Prime Contractor and participate as a Subconsultant on another team's proposal?

A1 Offerors may bid and participate in another bid with another company as a subcontractor. The District has no contract with subcontractors, and we would like to view each offer on its own merits.

Q2 Could you please confirm that the stated budget of $60,000 and the period of performance ending September 30, 2026, are correct?

A2 Offerors are encouraged to provide proposals representing the actual costs necessary to complete the work, inclusive of profit. The District expects all work to be complete no later than March 1, 2027.

Q3 Page 1 (of 42303IFB26) notes that “All Work” must be completed by September

30, 2026. What exactly is included in “All Work”? I am asking because proposals are not due until August 10, 2026, which means that there is only slightly more than a month and a half to get everything finished if “All Work” includes the following tasks: (1) full survey of the 2,722 acres of the Pablo Creek Conservation Area (PCCA), (2) delineation of any sites discovered, (3) analysis of whatever artifacts and other cultural remains are recovered, (4) preparation of a draft report, (5) review of the draft report by the Florida SHPO, (6) revisions to the draft report based on comments received from the SHPO, and (7) preparation and submittal of the final report. Given that the SHPO usually requires at least 30 days to review a draft report, that only leaves less than a month to do everything else. Having conducted thousands of cultural resources investigations over more than 50 years, my experience tells me that it will be impossible to complete “All

Per Addendum 1

Work” by September 30, 2026, if “All Work” includes the seven tasks noted above.

If “All Work” means only the field investigations (i.e., Tasks 1 and 2 of the above), that also will be extremely difficult, if not impossible, to complete by September 30, 2026. Even if only half the survey area is considered to have a high or moderate probability for containing cultural resources, that’s likely thousands of shovel tests spaced at 25-m intervals, each of which needs to be excavated to at least 1 m deep (unless bedrock is hit), screened for cultural material, and with its stratigraphy recorded. The remaining low-probability areas also cannot be ignored, as they will still need to be shovel tested, albeit at greater spacing than 25

m. And that is not counting the unknown number of additional shovel tests that will need to be excavated to delineate the areal extent any sites discovered. I just do not see how even the fieldwork can be completed in by September 30, let alone “All Work.”

A3 The District expects all work to be complete no later than March 1, 2027.

Q4 How firm is the estimated budget of $60,000 that also is mentioned on page 1 of 42303IFB26? Again, in my over 50 years of conducting archaeological research across the U.S. Southeast, including projects in Florida, I don’t see how any firm, or even a university using students, can survey 2,722 acres, excavate thousands of shovel tests, delineate several sites, analyze the recovered material, and prepare both draft and final versions of a report for that amount of money. I would think a survey of this magnitude would require a budget of several hundred thousand dollars, at least.

A4 Offerors are encouraged to provide proposals representing the actual costs believed necessary to complete the work, inclusive of profit.

Q5 The two previously recorded canoes (8DU21513 and 8DU21514) mentioned on page 3 of the RFQ have not been evaluated by the SHPO. Will revisitation and documentation of the canoes be required as part of the survey?

A5 A revisit and site monitoring will be part of this solicitation. The Master Site files can be provided.

Q6 Is there a boat ramp or kayak launch point within the project area to access the two previously recorded canoes (8DU21513 and 8DU21514) and investigate for additional shoreline resources?

A6 There is an area where kayaks can be launched after an approximately 600-foot portage. A dolly can be used; however, the route has many low cypress knees that could pose a problem for vehicles. This area may be mowed by the time of the survey, but that is not certain. The launch is followed by about a 4,000-foot paddle (see highlight in map below). The creek is not significantly tidally influenced. The closest public boat ramp is McCue Park:

Q7 The project is on State land and requires obtainment of a 1A-32 permit through the Bureau of Archaeological Research (BAR). It can take the BAR up to 30 days to issue a 1A-32 permit. If the proposals are due on August 10, 2026, and the 1A- 32 permit is not issued until early September, will there be flexibility to extend the September 30, 2026, project completion date?

A7 The District expects all work to be complete no later than March 1, 2027.

Q8 Please clarify if we are to include a cover letter, firm qualifications, technical methodology, and resumes in addition to the required forms and documentation listed on pages 12-13, Part 2, 2.3, How to Assemble Your Submittal section of the RFQ, or is our response only to be comprised of the forms and documentation listed in section 12-13, Part 2, 2.3, How to Assemble Your Submittal section of the RFQ.

A8 Please note that this requirement is solicited as an Invitation for Bid, not a Request for Qualifications. Beginning on Page 12, Part 2, Section 2.3, the cover letter consists of Page 1 of the IFB, completed by the respondent. The Bid Form is Page 11 of the IFB and is listed as Form 2 in the solicitation. The General Qualifications Questionnaire, Similar Projects Form, Certificate as to Respondent's Authority to Do Business in the State of Florida, Affidavit as to Non-Collusion and Certification of Material Conformance with Specifications, Drug-Free Workplace Form, and Submittal Acknowledgement Form are found in Part 3, beginning on Page 19 of the IFB. The respondent-provided documentation described on Page 13, Part 2, Section 2.3, is required as part of each offeror's submittal. Firm qualifications beyond the minimum qualifications stated on Page 12, Part 2, Section 2.1, and illustrated through Pages 20 and 21, Part 3, are not expressly requested. Technical methodology for the Pablo Creek CA CRAS is not expressly requested, but techniques and methodologies may be reviewed if provided as part of an offeror's similar project details. Resumes of key employees are not expressly requested. In all cases, the District reserves the right to request additional information from any respondent prior to award, in accordance with Page 12, Part 2, Section 2.3 of the IFB.

Q9 We wanted to confirm that all work would need to be completed by September

30, 2026. Would this just be for the predictive model, or is that for all fieldwork, reporting, and approvals?

A9 The District expects all work to be complete no later than March 1, 2027.

Q10 We wanted to confirm that the anticipated budget is $60,000. Again, is this just for the predictive model, or for all fieldwork, reporting, and approvals?

A10 Offerors are encouraged to provide proposals representing the actual costs necessary to complete the work, inclusive of profit.

Q11 For fieldwork, are there anticipated acreages for high, medium, and low probability currently to aid in general budgeting and assumptions?

A11 A LiDAR map can be provided if that would help with prioritization.

Q12 Can any GIS and archaeological reports be shared at this time?

A12 The District can provide a LiDAR map as well as the files from the Master Site

File

Q13 In addition to the invitation to bid, can the solicitation package be shared with us?

A13 The solicitation package is included within the Invitation for Bid posted on

DemandStar, Central Bidding, and MyFloridaMarketplace. Bidders are welcome to share the solicitation package and the full Invitation for Bid may be provided by emailing a request to the Procurement Director JBAshwor@sjrwmd.com

Q14 We noticed the bid form requests unit prices, but there is not a space to add those unit prices to the current form. How would the District request those prices be added to the submission?

A14 The bid form is page 11 of the Invitation For Bid and is a lump sum total bid. A revised Bid Form is included in this Addendum.

Q15 Are we able to add on to certain forms? For example, the similar projects form leave space for two projects, and elsewhere in the IFB states that the respondent must have successfully completed a minimum of two projects. Could we make a copy of the form so we can include more than two projects?

A15 Yes. Respondents may make a copy of the Similar Projects Form to include more than two projects.

Q16 Does the District need a compliance level CRAS, or is the District looking for more reconnaissance?

A16 More of a reconnaissance level survey with delineation and description of any sites found, bearing in mind that the large ditch north of Pablo Creek itself will be restored by filling it in with spoil from the adjacent berm. We want to prioritize that area with that project in mind.

Q17 Are there any other more specific mapping images that identify where within the acreage the CRAS would need to be performed? And if so, could those maps be shared with respondents?

A17 We would like the entirety of the property to be surveyed, with priority on the canal/ditch north of Pablo Creek itself.

Q18 Is there any chance of the APE being refined based on known project plans?

A18 The highest priority is a survey of the man-made canal/ditch north of Pablo

Creek

Q19 Is site delineation included in the overall budgeted cost?

A19 Yes

Note to Offerors / Bidders:

A revised Statement of Work has been provided below to address numbering issues in the posted solicitation. No information in the Statement of Work has changed other than numbering.

A revised Bid Form has been included below to replace the bid form on page 11 of the Invitation for Bid. The revised Bid Form removes “Unit Price” as a required field.

Five additional maps are included herein and provided below for offeror/bidder information and situational awareness.
