Q&A

Discipline Sheet Detail Spec Description NPS Response

1 General 01 57 19.12 Para 3.1.B

Specification section 01 57 19.12 Noise & Acoustics Management includes overly stringent restrictions related to allowable noise levels, for instance limiting noise over 80 dB(A) (such as pile driving), to 3 minutes per hour. Due to the nature of the project, the noise level restrictions would severely impact our ability to perform the project work. During project execution there will be noisy activity associated with work such as demolition, excavation, marine work, pile installation, and other heavy equipment operations and construction activities within the project site and in the immediate proximity of the site. Please remove these noise restrictions as they are not realistic with the extent of work required for this project.

Spec Section can be struck. Being Reviewed by the Designer of Record for a more thorough response;

however, it is anticIpated that Contractor would need to follow the Collier County Noise Code

Ordinance

2 Civil Civil 01 11 00 Para 1.11.B;

Div 31

Specification section 01 11 00 Paragraph 1.11.B states, "In case of conflict between [Soils Investigation] report and drawings and specifications, the drawings and specifications govern." The Soils Investigation Report discusses a preload program involving placing fill to 2 feet above proposed grades and allowing settlement and consolidation to occur for 90 days prior to grading, foundation and utility work. Neither the Division 31 specifications nor the drawings contemplate this work. Please confirm whether the preload program discussed in the Soils Investigation Report is a requirement of this project.

Being Reviewed by the Designer of Record for a more thorough response and by contracting in context of FAR 52.285-8. However, if the preload program is required, review of visitor access and site closure times and locations, and solutions to address the time impact of this program also will be addressed.

3 Civil Geotechnical Report

Please confirm the preload program outlined in the geotechnical report is required at all fill areas and not limited to paved areas and path of new utilities only

G106

Amendment 4 and 5 Q&A responses

Amendment 4 and 5 Q&A responses confirm that the phased turnover dates listed in 01 11 00 Paragraph 1.3 do not apply. General Note E on Drawing Sheets G105 and G106 still includes closure windows for the kayak launch and the marina boat tours of a maximum of 3 months between June 1 thru November 1. The preload program described in the geotechnical report requires a 90 day preload, so the limitation of the construction phase where the kayak launch is to be completed to 3 months does not allow for demolition, grading, preloading, removal of preload material, and then the permanent work. Please confirm that the closure limitations and associated Stages/Phases on this drawing do not apply, and that the only scheduling constraint that applies is the 730 calendar day period of performance. Should these limitations and stages/phases still apply, there would be schedule impacts associated with the 90‐day preload program at multiple phases, and additional costs such as subcontractor remobilization and temporary accommodations for public access.

5 General Amendment 4 Q&A

Responses 43, 44, 45

Amendment 4, Q&A responses #43, 44, 45 (Round 2 Q&As 18, 19, 20) indicate that the NPS's intent is to award all CLINs, and that if bids come in above available funds then a formal path will be issued regarding tying in significant fill areas to existing grades at the marine bulkhead, other site areas and utilities. It is not possible for the bidding contractors to provide a firm fixed price for the base bid scope of work without knowing how the NPS may subsequently change the scope of the project if CLINs 12 and 14 are not able to be exercised. Due to the current format of the Bid Form, there are areas of 3‐5' of fill directly adjacent to the marine bulkhead and other site areas with hardscapes, utilities, etc.

Without understanding how this scope may be unilaterally changed by the NPS, the only way to mitigate risk is to include significant contingency dollars which will exacerbate the potential issue of funding availability. In order to drastically reduce cost to the NPS, we recommend including CLINs 12 and 14 within the base bid if it is truly the intent to award these CLINs. Otherwise, we will need an alternate design to understand how the proposed grades and hardscapes should tie back into the existing grades.

Being Reviewed by the Designer of Record for a more thorough response with regard to the fill and preload issue. This question initially was answered in Amendment 05, but additional information will be provided.
