JILONA SHORELINE STABILIZATION

1. Question: Modules that meet the spec 2.02 could be better served with three longer modules. The proposed modules would be 1-60’x10’; 1-56’x8’; 1-28’x8’. Is this permissible?

Answer: The current specification for floating dock requires concrete. No concrete modules shall measure greater than 20 feet in length or greater than 10 feet in width. Pile spacing will remain as proposed on Drawings. The Contractor may propose alternative floating dock materials (FRP) with measurements greater than this specification subject to Government and Engineer approval through signed and sealed shop drawings and calculations.

2. Question: What is the quantity of rock required for the options that require rock?

3. Question: Are there more details of the staircase that goes from the retaining wall to the seawall and the seawall to the beach?

Answer: Yes. Details added to Drawings.

4. Question: Does the #57 stone under the sheet piles go along the sheet pile or only where 6” corrugated pipe goes?

Answer: The gravel drain extends along the entire alignment of sheet pile.

5. Question: Please provide the width of the crushed concrete pad for the retaining wall.

Answer: Crushed concrete pad is part of the free-standing block wall design. Free-standing block wall is preliminary design only. Contractor to engage a specialty engineer licensed in the state of Florida to submit shop drawings and final design calculations during construction for Engineer approval. Shop drawings and calculations must be signed and sealed by a licensed Professional Engineer in the state of Florida.

6. Question: Can a non-structural 2,500 psi concrete 6” thick be substituted for crushed concrete leveling pad on the retaining wall?

Answer: See answer to Question #5 above.

7. Question: Could you provide CAD drawings to assist with quantity take-offs?

Answer: Yes. Provided with this response package.

8. Question: What is the anticipated date (or range of time) that the project will be awarded?

Answer: The government anticipates awarding this prior to the end of fiscal year 2024.

9. Question: What is the anticipated date (or range of time) that the Contractor can commence work onsite?

Answer: Following receipt of performance and payment bonds and insurance and issuance of notice to proceed.

10. Question: Reference specification section 0135 43-1.01D - Please provide the applicable FDEP and USACE Permits.

Answer: Attached to Specifications.

11. Question: Referencing Plans, Sheet C-5 AND Sheet C-2, Staging & Construction Access, Note #6 – If Contractor performs clearing within all of the limits shown on Page C-5, is it then required to re-plant similar native vegetation within these same limits after construction, or can the areas remain cleared?

Answer: Clearing and grubbing shall be performed as needed for construction. Drawings present maximum available space, but the Contractor shall minimize these areas as required to complete work. Impacted areas will have to be restored to pre-existing conditions by grassing (seeding/sodding) as presented on updated Drawings and Specifications. Planting is no longer a part of the scope of work other than preservation of government specified trees (detailed on Drawings).

12. Question: Referencing Plans, Sheet C-15 and C-27 – Please revise the plan views on these pages to include the elevations on the contour lines similar to other pages.

Answer: Contour labels added to the referenced sheet.

13. Question: Referencing Plans, Sheet C-16, C-17, and C-18 – Please provide plan view scales on these pages.

Answer: Scales added. Please see updated Drawings.

14. Question: Referencing Plans, Sheet C-6 – Please provide engineered details for the 3 EA access stairs with platforms that drop from the free-standing block wall and the 4 EA that drop from sheet pile wall. At minimum, we need to know their plan dimensions, piling foundation details, framing, decking and handrail details, and how they connect to adjacent wall structures, to provide accurate pricing.

Answer: Details added; please see updated Drawings.

15. Question: Referencing Plans, Sheet C-20, Detail F5 – Please provide the clear distance required for inside handrail post face to opposing inside handrail post face. We are trying to determine if this is 8’-0” or some other dimension.

Answer: Dimension added to Drawings; dimension is 8-ft.

16. Question: Referencing Plans, Sheet C-20, Detail F5 – Please provide the actual width of decking required. Based on the plan view detail, which shows 6’-8” as the center-to-center dimension of 12” diameter piles, the bidder can only infer that the deck must be minimum 8’-2” wide to cover all exterior stringers (6’-8” + half of a pile @ 6” x 2 sides + 2 ea. exterior stringers @ 1.5” x 2 sides). This 8’-2” deck dimension would not be cost effective since the standard widths for FRP deck panels are 8’-0” wide and 10’-0” wide. Meaning contractor would need to purchase 10’ wide decking and trim and waste a significant amount of the product. Please clarify.

Answer: Dimension of the deck width at Detail F5 is 8-ft wide; dimension added to Drawings.

17. Question: Referencing Plans, Sheet C-20, Detail F5 and Sheet C-21, Details A1 and A5 – Is the intent to have the deck be flush with the inside edges of the handrail posts or should the deck overhang the exterior stringers and be notched around the posts. Please understand there is a significant cost increase to notching this decking around all the posts.

Answer: See answer to Question 15 & 16 above. The deck shall extend inside post to inside post (8-ft wide typical).

18. Question: Referencing Plans, Sheet C-21, Detail A - Based on the plan view detail, which shows 6’-8” and 8’-0” as the center-to-center dimensions of 12” diameter piles, the bidder can only infer that the deck must be minimum 16’-2” wide to cover all exterior stringers (6’-8” + 8’-0” + half of a pile @ 6” x 2 sides + 2 ea. exterior stringers @ 1.5” x 2 sides). But the clear distance required for inside handrail post face to opposing inside handrail post face is 16’-0”, which should equal the deck width. Please clarify.

Answer: The deck is 16-ft wide (inside post to inside post); drawings have been revised to clarify.

19. Question: Referencing Specifications, Section 06 13 00, Part 2.08 – Are the minimum moisture contents (19% and 25%) listed for varying lumber sizes to be field measured periodically during delivery and installation of wood? If so, please provide the testing specification that describes testing methods and frequency of testing.

Answer: The moisture content specification derives from the AWPA U1 and T1 standards and ensures the structural integrity of the member. The specification has been updated to state the lumber shall be the specified moisture content prior to delivery (not as observed at the project site). The Contractor/supplier shall provide formal documentation of the moisture readings. “KDAT” product is not specifically required. The Contractor will be required to ensure all dimensional lumber at the site shall be covered with tarps and blocked above the ground prior to installation.

20. Question: Referencing Specifications, Section 06 13 00, Part 2.08 – If the 19% and 25% or less moisture contents are to be field measured periodically at deliveries and during installation of wood, please clarify whether the testing will be the scope and financial responsibility of the Owner or the Contractor.

Answer: See response to previous question above.

21. Question: Referencing Specifications, Section 06 13 00, Part 2.08 – 19% and 25% or less moisture content at the time of installation is an extremely unique specification, and nearly impossible to estimate due to uncontrollable outdoor rain/humidity conditions after material is delivered to the site and stored prior to installation. Is the intent of this note to ensure that the wood material is kiln dried after treatment (KDAT) to 19% and 25% or less moisture content, not at the time of installation? We have built hundreds of dock structures in South Florida and have never been held to a requirement like this.

Answer: See response to Question #19 above.

22. Question: Referencing Specifications, Section 06 13 00, Part 2.08 - If the intent of this specification is to ensure that the wood material is kiln dried after treatment (KDAT) to 19% and 25% or less moisture content, would certifications from the manufacturer suffice for proof of conformance to the project specifications?

Answer: Yes. See response to Question #19 above.

23. Question: Referencing Specifications, Section 06 13 00, Part 2.08 - If the intent of this specification is to ensure that the wood material is kiln dried after treatment (KDAT), please specify as such, and understand that this type of wood is much more susceptible to bowed ends, splits, checks, cracks, will have a much higher waste percentage, and is not conducive for screwing into.

Answer: See response to Question #19 above.

24. Question: Referencing Plans, Sheet C-23 – The handrail top cap is called out to be “2x10 composite handrail or approved equivalent”. This is confusing because there is nothing in the specifications about this and there are dozens of 2x10 “composite” materials that can be used in this application, and we believe there no “approved equivalent” to a generically specified composite material, i.e. its either composite or it’s not, correct? Please specify the brand, model, and color of decking to price since prices vary widely.

Answer: HDPE composite material is intended for the handrail top cap. Weardeck was used for basis of design. Color is to be in-kind as existing observation pier at the site (Gray).

25. Question: Referencing Plans, Sheet C-23 – Regarding the previous question, if no composite material is specified, can bidder assume to bid the most cost-effective composite material available?

Answer: See response to Question #24 above.

26. Question: Referencing Specifications, Section 06 13 00, Part 2.07E. – Will 0.60 CCA be an approved alternate treatment for stringers and blocking (opposed to 0.60 ACQ)? This is the typical treatment for these members in this environment.

Answer: Yes. Specification updated to 0.60 CCA. Handrail timber components (direct contact) shall be 0.60 ACQ or CA-C use category UC4B.

27. Question: Referencing Specifications, Section 06 13 00, Part 2.07E. – Are bidders to assume that handrail southern pine posts and side rails are to be treated to 0.60 ACQ? And will 0.15 or 0.31 CA-C be approved alternate treatments for any of these members?

Answer: Yes, CA-C is acceptable. CA-C treatment must meet use category UC4B (.31).

28. Question: Referencing Specifications, Section 06 13 00, Part 2.02A. – Can the cross bracing that required 2.5 CCA treatment be rough sawn opposed to S4S dressed? This is the typical dressing for these members with this treatment requirement.

Answer: Yes, cross-bracing shall be rough sawn based on specified treatment. Specification revised.

29. Question: Referencing Specifications, Section 06 13 00, Part 2.03C and D. – Are you sure that you are okay with having the handrail posts and side rails as #2 Grade opposed to #1 Grade?

Answer: Timber handrail components shall be No.1. Specification revised.

30. Question: Referencing Plans, Page C-23, Handrail Details – Do bolts that secure handrail posts to framing need to be hex head bolts (as drawn, but not specified) or can they be all thread rods with nuts and the ends of the rods leaving all thread slightly exposed beyond the nuts, and outboard of the posts? There is a significant price increase to procure 24” long hex head bolts, opposed to using all thread rod.

Answer: The Engineer’s intent is to use 316 S.S. all threaded rods. Bolt in Drawings updated.

31. Question: Referencing Specifications, Section 06 13 00, Part 2.01B.

0. Are there timber “indicator” (a.k.a test) piles on this project, and if so, please provide their locations and more detailed requirements.

Answer: Test pile program added to Drawings and Specification.

0. Are all 12” diameter piling called out on plans to be furnished a minimum of 12” diameter 3 ft. down from the head (butt) of the piles?

Answer: Yes.

0. Are all 8” diameter piling called out on plans to be furnished a minimum of 8” diameter 3 ft. down from the head (butt) of the piles?

Answer: Yes. Drawings are revised to require 10” Ø butt piles for stair applications.

32. Question: Referencing Plans, Sheets C-15, C-16 – Please provide minimum butt of the timber signage and fender pilings on these drawings?

Answer: Minimum embedment depth is 19 ft shown on Drawings.

33. Question: Referencing Plans, Sheets C-3, Note C.2.a. and Note D.3.a. vs. Sheet C-15 / C-16 – The notes for the fender and signage piles call for all 30 ft long timber piles for the piles shown on plan view sheets C-15 and C-16. On the plan views the piles are annotated to have head elevations of +8 NAVD, and minimum embedment’s of 19’. If we follow the annotative notes this means these piles could be anywhere from neat 28 ft. to 44 ft. long based on existing mudline elevations. Are bidders to follow the annotative notes on sheets C-15 / C-16 or the General Notes from sheets C-3 to determine the bidding pile lengths?

Answer: 30 ft pile length mention in Drawings is removed. Embedment required is 19-ft with pile head at +8’ NAVD.

34. Question: Referencing Specifications, Section 06 13 00, Part 2.01C. – The available thicknesses for HDPE pile wrap are 30 mil (0.030 in) and 60 mil (0.060 in) and the specification calls for minimum 1/32” which equals 0.03125”. Will 30 mil pile wrap suffice or must Contractor upsize to 60 mil?

Answer: 30 mil pile wraps will suffice.

35. Question: Referencing Specifications, Section 06 13 00, Part 2.01C. – what is meant by “from pile cap”? is this referring to a timber pile cap that supports stringers or a plastic pile cap that goes on the head of a pile. Could you please provide a minimum elevation (in NAVD) or a distance above MHW for top of HDPE pile wrap on all timber dock and fender piles?

Answer: In Section 06 13 00, Part 2.01C language stating “from pile cap” is referencing the timber pile cap that supports the stringers. Pile wraps shall extend up to elevation +6’ NAVD. Specification revised.

36. Question: Referencing Specifications, Section 06 13 00, Part 2.01C. – Is pile wrap required for bluff stair and landing piles that are installed into a grade above MHHW?

Answer: No. Drawings revised.

37. Question: Referencing Plans, Sheet C-17 & C-18 - Is Contractor required to follow the pile bent quantities and layouts on these drawings, or can layouts be re-designed by Contractor to accommodate the specified 10’-0” maximum bent spacing and 5’-0” maximum hand rail post spacings?

Answer: No. Dock shall be built as presented in Drawings. Field modification can be made during construction at the approval of the Engineer.

38. Question: Referencing Specifications, Section 06 13 00, Part 3.02-B.1. – This specification states that “Piles shall be laterally supported during driving”. We interpret this to mean piles should be templated or driven with fixed lead systems, and that free swinging leads would not classify as lateral support during driving. Is this a correct assumption?

Answer: Contractor can use free swinging leads, but pile location and plumbness tolerances remain as detailed in Specifications. Any pile out of tolerance is subject to rejection by the Engineer. Concrete floating dock piles shall be installed by fixed lead system to ensure accuracy to accommodate floating dock.

39. Question: Referencing Specifications, Section 06 13 00, Part 3.02-C.2. and Plans, Sheet C-19 – Our understanding is that the required minimum ultimate bearing capacity for the boardwalk piling that have a minimum tip of EL -27, will require a capacity of 15 tons, calculated by a minimum blow count determined by the FHWA Modified Gates Formula, and there will not be PDA tests or a test pile program of any kind. Please confirm.

Answer: Confirmed. PDA testing is not required.

40. Question: Referencing Specifications, Section 06 13 00, Part 3.02-C.2. and Plans, Sheet C-19 – If the previous question is a correct understanding of the requirements and Contractor plans for ordering piles to stop at or slightly below minimum tip EL -27, and piles do not reach capacity at this elevation, and Contractor runs out of pile to drive, what will happen in that situation? Especially if Contractor has ordered and stored a high volume of future piles that might not be long enough to meet bearing capacity. Maybe it is worth specifying a test pile program?

Answer: A test pile program shall be completed. Drawings revised to indicate test piles.

41. Question: Referencing Specifications, Section 06 13 00, Part 3.02-C.2. and Plans, Sheet C-19 – If timber pilings do not reach capacity at or slightly below minimum tip EL -27, and Contractor runs out of pile to drive, will he be compensated by the Owner to pull that pile and replace with a longer piling?

Answer: A test pile program shall be completed. Drawings revised to indicate test piles.

42. Question: Referencing Specifications, Section 06 13 00, Part 3.02-C.2. and Plans, Sheet C-19 – Referencing the previous two questions. If EOR agrees that a test pile program is a worthwhile exercise to protect to Owner and the Contractor, please specify this in the bid, and please confirm that Contractor would be compensated via change order for ordering approved pile lengths (subsequent to test pile program) that exceed the lengths that would have met the minimum tips shown on the plans at bid time?

Answer: A test pile program shall be completed. Drawings revised to indicate test piles.

43. Question: Referencing Specifications, Section 06 13 00, Part 3.02-C.2. and Plans, Sheet C-19 – Our understanding is that the required minimum ultimate bearing capacity for the boardwalk piling that have a minimum tip of EL -27, will require a capacity of 15 tons. Please specify the required minimum ultimate bearing capacity of the timber piles that support the west and east bluff stairs and landings, if any.

Answer: 4 tons. Drawings updated.

44. Question: Referencing Specifications, Section 06 13 00, Part 3.02-C.2. and Plans, Sheet C-15 & c-16 – Our understanding is that the required minimum ultimate bearing capacity for the boardwalk piling that have a minimum tip of EL -27, will require a capacity of 15 tons. Please specify the required minimum ultimate bearing capacity of the signage and fender piling, if any.

Answer: No minimum ultimate bearing capacity is required for signage and fender piles.

45. Question: Referencing Specifications, Section 06 13 00, Part 3.02-D.2 and Part 3.02-F.1. – If timber pilings hit hard soils and Contractor is unable to advance piling to minimum tip with the use of jetting and driving (i.e. early refusal), will punching and drilling be compensable via change order?

Answer: Contractor may use punching and drilling to drive piles to minimum tip elevation if obstructions are encountered (with Engineer Approval). Contractor shall employ BMPs to adhere to permit conditions (turbidity). Punching and drilling for the timber dock during construction would be considered a differing site condition if there is difficulty in driving.

46. Question: Referencing Plans, Sheet C-3, Note G. AND Sheet C-27 – Please elaborate on the statements “selective placement of proprietary artificial stabilization structures (i.e. reef balls, shehive)” and “Bid Option 6 may result installation of experimental stabilization units” in the notes. We are unable to find any details on these items on Bid Option 6 Plan (sheet C-27). How are bidders supposed to price this without details? Or are these future design items that will be change orders?

Answer: Cost Bid Option 6 as limestone breakwaters, if this changes during construction, it would be considered a differing site condition.

47. Question: Reference Specification, Section 0135 43-2.01.A. - The section states ‘Contractor is advised there shall be zero impacts to seagrass (turbidity). Contractor shall furnish adequate turbidity curtains accordingly’. Is it the intent of this article that there is a zero (0) NTU difference in turbidity levels allowed between the compliance site turbidity level and the corresponding background turbidity level?

Answer: Correct. Please review permits attached that outline regulatory turbidity requirements.

48. Question: Reference Plans, Sheets C-7 and C-8. - Please provide the required tip elevation of the AZ19-700 steel sheetpiles.

Answer: Minimum tip elevation: -20’ NAVD. Drawings updated.

49. Question: Reference Plans, Sheet C-8, TYPICAL SEAWALL CROSS-SECTION, and the note related to the sheetpile coating on the right hand side of the detail that states ‘AZ19-700 STEEL SHEETPILE UPPER 20’ COATED WITH MACROPOXY 646 (BOTH SIDES)’ - Specification section 35 31 16-2.01.A seems to require a three (3) coat sheetpile coating system – (1) zinc primer full length both sides, (2) Macropoxy 646 top 20’ both sides, (3) Sher-Loxane 800 top 20’ both sides. Please clarify the required steel sheetpile coating system.

Answer: The coating on sheet pile shall be 3 coat system as detailed in specifications. Required dry film thicknesses and coats:

50. Question: Reference Specifications, Section 03 30 00-3.04.A.1. - The section requires a 7 day moist/wet cure consisting of Methods 1 and 2 when the concrete contains silica fume. Based on the mix design provided in specification section 03 30 00-2.03.B., it appears the sheetpile cap concrete mix design does require silica fume (7-10%), and therefore the cap will require the 7 day cure comprised of Method 1 and Method 2. Please confirm, or clarify if different.

Answer: Yes, the silica fume pile cap will require the 7-day cure comprised of Method 1 moist curing for at least 72 hours followed by Method 2 moist curing for an additional 4 days.

51. Question: Reference Plans, Sheet C-8, TYPICAL SEAWALL CROSS-SECTION, and the note related to the backfill material behind the Free Standing Block Wall - The note states ‘CLEAN SAND BACKFILL WITH LESS THAN 12% PASSING THE 200 SIEVE’. Does the existing material on site meet these requirements, or will the sand fill backfill material for this area need to be imported from off-site?

Answer: The intent is to reuse existing on-site material from construction. The material must be free of debris and organics.

52. Question: Reference Plans, Sheet C-8, TYPICAL SEAWALL CROSS-SECTION, and the note related to the sub-base material below the wall 12” base material - The note requires that the ‘SUB-BASE IS COMPACTED TO 95% MODIFIED PROCTOR, MIN LBR:40. Is the in-situ material suitable for the sub-base material and meeting these requirements, or will material for this area and use need to be imported form off-site?

Answer: The Government expects the in-situ material to be suitable to meet these requirements. No material is expected to be imported from off-site.

53. Question: Reference drawing C-8, TYPICAL SEAWALL CROSS-SECTION. - There is 57 stone gravel drain material behind the free-standing block wall, and underneath the pile cap. The notes require that the 57 stone drain material under the pile cap is granite or river-rock, and limestone is not allowed. Is the drain material behind the free-standing block wall also required to be granite or river rock, or can it be limestone?

Answer: All features and notes associated with the free-standing block wall on the Drawings are preliminary design (see note on Drawings). The contractor is to engage a Florida licensed professional engineer specializing in large block wall design to finalize design including all features associated with the block wall (i.e foundation pad and drainage system). The design calculations and shop drawings (signed and sealed) shall be submitted to the Government and Engineer via submittal for approval.

54. Question: Reference drawing C-8, TYPICAL SEAWALL CROSS-SECTION. - What is the spacing of the 4x4 timber posts? And what are the requirements for the post timber and treatment?

Answer: Maximum spacing of 6 ft (post and rope). Southern pine 0.31 pcf CA-C or 0.60 pcf ACQ (category UC4B) is the required fence post timber and treatment. See updated Timber Specification.

55. Question: Reference specification section 04 22 00-1.07.A. related to the RWIC (Retaining Wall Installation Contractor). Must the installer meet the requirements and qualifications listed in this specification section, or can the wall supplier (Redi-Rock/Truemont) provide on-site technical support so the Bidder/Prime Contractor can self-perform the Work?

Answer: The installer must be the qualifications outlined in section 1.07 of the specification 04 22 00.

56. Question: The notes on sheet C-2 related to the GEOTECHNICAL REPORT appear to state that the REPORT is part of the Contract Documents, and that the Contract Documents were formulated based on its findings and directives. The notes on C-2 further go on to state that the Contractor is required to review the REPORT, be familiar with the requirements, and incorporate the findings into the Work. Terracon stated in several areas of the REPORT that the timber piles must have not less than 30 feet of embedment and penetrate to a tip elevation that is no higher than -40.0’ NAVD. The details shown in the WATERFRONT BOARDWALK ELEVATION on sheet C-19 of the Contract Documents require that the timber piles are installed to a minimum tip elevation of -27.0’ NAVD or higher in other locations. The required tip elevation shown in the Contract Documents is higher than what is required in the Geotechnical Report and seems to contradict the REPORT’s findings and installation requirements. Please clarify.

Answer: Minimum tip elevations updated on Drawings. The geotechnical report has been updated.

57. Question: Reference Specifications, section 01 35 43-1.01D – if FDEP and USACE Permits are not available prior to bid, is it fair to assume that any enforceable conditions from them that could not have been foreseen at bid time, and could have cost implications, will be compensable via change order?

Answer: FDEP permit and USACE permit are now provided as an attachment to Specifications.

58. Question: Reference Specifications, Section 03 41 33.01, Part 1.02.C.– It appears that a third party piledriving inspector (PDI) is required for the concrete pile installations, and is the financial responsibility of the Contractor. Please confirm this PDI is not applicable to the timber piling scope.

Answer: Correct. PDI is only required for the concrete floating dock.

59. Question: Reference Specifications, Section 03 41 33.01, Part 2.02.A which states that “pre-drilling will not be permitted” and Reference Plans, Sheet C-26, Detail B which states that concrete pile shall be installed “full length of the piles or until refusal BUT NOT LESS than the minimum pile tip elevation”. These concrete dock anchor piles have a minimum tip around 14 ft into limestone, so what happens if refusal is met prior to minimum tip in a hard limestone layer and Contractor is not permitted to pre-drill, and drilling is the only way to advance the pile(s)?

Answer: Pre-drilling and punching may be required for floating dock construction. Specification updated. PSC pile now require shoes. Turbidity requirements are presented on permits.

60. Question: Reference specification section 03 41 33-2.01C & D – We have had two different pile suppliers tell us that FDOT does not have any pre-approved fly ash to meet this specification. Would the FDOT Pre-Approved mix # 01-1424 be an acceptable alternative?

Answer: No. Concrete mix is as specified in Specification. The Contractor may propose to substitute fly ash for 55% slag (ASTM C989, Grade 120). Silica fume requirement remains. All concrete mix designs must be submitted during construction subject to Engineer approval.

61. Question: Reference specification section 04 22 00-2.05 A-01 Drainage HDPE pipe shall be 4” diameter according to this section, but the plans call for 6” HDPE pipe. Please clarify.

Answer: All features and notes associated with the free-standing block wall on the Drawings are preliminary design (see note on Drawings). The contractor is to engage a Florida licensed professional engineer specializing in large block wall design to finalize design including all features associated with the block wall (i.e foundation pad and drainage system). The design calculations and shop drawings (signed and sealed) shall be submitted to the Government and Engineer via submittal for approval.

62. Question: Reference specification section 04 22 00-2.05 A-01 What type and what rating (i.e. DR11 vs DR26 and IPS vs. DIPS) is required for the HDPE pipe.

Answer: All features and notes associated with the free-standing block wall on the Drawings are preliminary design (see note on Drawings). The contractor is to engage a Florida licensed professional engineer specializing in large block wall design to finalize design including all features associated with the block wall (i.e foundation pad and drainage system). The design calculations and shop drawings (signed and sealed) shall be submitted to the Government and Engineer via submittal for approval.

63. Question: Reference Specification, Section 01 11 00, 1.01, Part 4a – which states the scope is to “Preserve Government-specified specimen trees at temporary on-site location; replant following wall construction”. Please provide plans and specifications for this scope, or at least some more description about what the requirements are.

Answer: Notes added to clearing and grubbing sheet for further clarity.

64. Question: Reference Specification, Section 01 11 00, 1.01, Part 4b – which states the scope is to provide “New native vegetation planting at specified areas”. We are unable to find the specified areas on the plans. Please clarify.

Answer: Planting is removed from the scope of work. Preservation of government specified specimen trees is part of this scope of work. See notes on clearing and grubbing sheet. There are areas that require sod or grassing (seeding). Drawings and specification updated.

65. Question: Reference Specification, Section 01 11 00, 1.01, Part 7a – which states the scope includes “Construction of a concrete pathway that leads to the pavilion from existing ADA pathway”. We only see a stabilized stone pathway on Sheet C-10 and cannot find a concrete pathway. Please clarify.

Answer: The pathway that leads to the pavilion from the existing ADA pathway will be concrete (sidewalk) for the upland portion and gravel for the remaining portion. See updated Drawings for new layout.

66. Question: Reference Specification, Section 01 11 00, 1.01, Part 8c – which states the scope includes, “Select revetment cross sections provide planters along structure centerline”. We are unable to find where these planters are on the plans, or any specifications, or qualifications required for installation. Please clarify.

Answer: This component is no longer included in the project.

67. Question: Reference Specification, Section 01 11 00, 1.01, Part 8d – which states the scope includes “Construction of a concrete pathway that leads to the pavilion from existing ADA pathway”. We only see a stabilized stone pathway on Sheet C-10 and cannot find a concrete pathway. Please clarify.

72. Question: Base Bid: Please provide sheet pile lengths. Can a wall profile drawing with sheet pile tip and top elevations shown be provided?

Answer: Sheet pile shall be 30 ft long with a minimum tip elevation of -20 ft NAVD. See updated Drawings for details.

73. Question: Base Bid: For the upper tier wall, please provide a wall profile.

Answer: The block wall top elevation and foundation elevation does not change along alignment. If the contractor requires a wall profile, it will be provided during construction.

74. Question: Base Bid: No performance anchors are shown on the drawings provided. Are Performance anchors sacrificial?

Answer: Performance testing (pull testing) will be required as presented in specifications (8 EA). Performance anchor locations will be decided during construction with discussion with the Contractor but generally every 100-ft along alignment. They are permanent structures.

75. Question: Base Bid: Can a helical anchor schedule be provided which includes helical anchor location, type, helix configuration and depth?

Answer: All helical information above is provided on Drawings.

76. Question: Base Bid: If the target capacity or torque for the helical anchor is not achieved at the 45 ft helical length how will the Contractor be compensated for additional anchor length or other remedy to achieve the target capacity?

Answer: The Engineer and Government will evaluate the actual testing results as compared to performance specification. If the helical anchors need to be lengthened or additional helical anchored need be installed, this would be considered a differing site condition.

77. Question: Base Bid: What is the remedy for achieving the target anchor capacity if the target capacity is not achieved with a 45ft anchor length?

Answer: The Engineer and Government will evaluate the actual testing results as compared to performance specification. If the helical anchors need to be lengthened or additional helical anchors need be installed, this would be considered a differing site condition.

78. Question: Base Bid: The SS225 helical anchors are not typically stocked and will require to be ordered special. For bid purposes, will GOV consider alternates which achieve the 77 kips ultimate strength? It is recommended by the supplier that the SS175 will provide 100 kips ultimate strength and is more readily available.

Answer: The SS225 is specified due to anticipated torque from installation. Based on helical model calculations (Chance), the SS175 is not sufficient given the anticipated installation torque.

79. Question: The experience requirements placed within the sheet pile wall, helical anchor and large block specifications will limit competition and preclude many competent bidders from the work due to the specificity of the requirements by anchor type, wall type, etc. Will the government consider the totality of the bidder’s experience with retaining walls and more complex civil works rather than limiting their experience to the specific type of wall construction or wall element?

Answer: The government assumes this question is in reference to past performance. If so, please reference L-10 and M-5 of the solicitation.

92. Question: Please provide detailed information related to the Contractor's limiting of access by the Public. Is there a length of time any area can be closed to Public use? What is the maximum size area and length of time permissible to close areas to the Public?

Answer: The Contractor may close areas immediately around active construction and staging within the “Construction Area” or limits of disturbance as shown on the plans for the duration of construction activities within that area and as needed to ensure safety of all staffs and public. Closures however, may not interrupt routine tours of the Lighthouse or impact events outside the Construction Area (a calendar of scheduled event will be shared with the construction contractor). Therefore, closures will move with construction as it moves through the various options within the contract. Potential contractors should be aware that there is mixed public sentiment of the project and larger closures may increase the risk of vandalism (such as tearing down fencing, removing marker stakes etc.). Therefore, the closures necessary shall be coordinated with the BLM prior to implementation to ensure public awareness messaging and law enforcement partners are aware.

Answer: The Government will have a brief wildlife training during the pre-construction meeting. Contractor is to review permits for wildlife requirements (now attached to Specifications).

106. Question: Option 4 calls for bank & shore to be placed under the boardwalk. We believe this will damage the timber piles. A possible alternative would be cable concrete. Would that be an option?

Answer: Option 4 calls for an armor stone revetment placed under the boardwalk. Contractor may propose alternatives for Owner/Engineer review and approval during construction.

107. Question: Will it be permissible to install a bulkhead at the south end below the block and sheet pile in order to access from waterside?

Answer: Only structures that are permitted and presented in the Construction Drawings may be constructed.

108. Question: The new statement of work shows NZ-26 steel sheet pile which is much larger and more expensive than AZ19-700 or equivalent as specified in the drawings. Please clarify what is required as there is a large price difference between the two sheet pile sections?

Answer: NZ19 sheet pile is required for this project. Drawings and Specifications updated.

109. Question: Press in sheet pile method with integral auger is now shown in this new scope of work due to slope stability but was never shown in the plans or specs and furthermore specification 3.02A states that pilings shall be driven without the aid of water jet, AUGERING or other soil loosening techniques unless approved by the government. This new requirement not only contradicts the specifications but provides nothing other than excessive cost since the slope’s stability can be easily managed by excavation and regraded which is already shown as part of the terrace wall plans. Please remove this requirement from the statement of work.

Answer: Press-in technology is not required for this project. However, Contractor is advised on the slope stability concerns with use of the vibration attachment. Use of water jetting, auguring, or other techniques may be requested during construction if installation challenges arise – subject to approval of the Engineer.

110. Question: The plan cross section shown on sheet C-8 only shows the post and rope fencing at the top of slope behind the block wall. Please provide clarification if this is required behind both the upper and lower walls?
