• There is no single statewide "moratorium" or specific time period on tree clearing and limbing.

26. Please provide the load ratings and any applicable weight restrictions for the roadway bridges that must be crossed to access the trailhead and project sites for each bridge location. During the site visit on July 28, 2026, several roadway bridges were identified along the access routes that did not have posted load limits. This information is necessary to determine equipment access, hauling restrictions, material delivery methods, and overall construction logistics.

• The roadway bridges are rated for HS-20 Loading. In addition, no parking is allowed on the bridges themselves. Contractor shall cross the bridges with a not to exceed HS-20 Loading and the axles must clear the vehicle bridges.

27. To help reduce the costs associated with transporting and installing the large glued-laminated timber (glulam) beams, including the potential need for specialized heavy equipment or helicopter lifts, would the U.S. Forest Service be willing to consider the use of Fiber-Reinforced Polymer (FRP) trail bridge systems as an approved alternative? FRP bridge components are significantly lighter than comparable timber members and can often be transported and installed using smaller equipment or manual handling methods, which may reduce construction impacts, improve site accessibility, and lower overall project costs. The US Forest Service issued a document entitled “A Guide to Fiber- Reinforced Polymer Trail Bridges” (https://www.fs.usda.gov/eng/pubs/pdfpubs/pdf06232824/pdf06232824dpi72.pdf) which outlines “The advantages of [FRP] composites in trail bridge applications include their light weight (figure 5), high strength, resistance to corrosion, and fast, easy installation.

These properties make them competitive with standard bridge materials in situations where access and construction present difficulties. [FRP] Composite materials can be designed to provide a wide range of tensile, flexural, impact, and compressive strengths.

They can be formed into any shape and colorants can be added to allow the structures to blend with most landscapes. The use of [FRP] composites eliminates any potential environmental impacts of treated wood or galvanized steel used in riparian environments”.

• No, the Forest Service will not consider the use of Fiber-Reinforced Polymer (FRP). The glulam beams shall be as currently designed.

28. Please let me know if either of the following two options would be acceptable alternatives for the Welded Wire 9GA PVC Coated Gabions the project is calling for. We are unable to supply Welded Wire in a PVC coating. Please see the available options below.

• Welded Wire Mesh 9GA GALVANIZED Gabion Baskets - (ASTM A974-97 Compliant)

• Twisted Wire Mesh 12GA PVC Coated Gabion Baskets - (ASTM A975- 97 Compliant)

• No, the welded wire shall be as currently designed (Welded Wire 9GA PVC).

29. Please confirm whether asbestos or lead is present on this project, and if so, provide the relevant documentation.

• No, asbestos and lead are not present on this project.

30. Is this project tax exempt?

• No, this project is not tax exempt for the contractor. Only Merchandise or services purchased by the Government is tax exempt. Contractors are encouraged to read FAR 52.229-3- Federal, State, and Local Taxes to ensure they are in compliance with the

31. When do you anticipate on site work starting?

• The onsite work is anticipated to start on October 2026.

32. Are third party inspections required?

• Yes, please refer to 100% drawings, G-105, III. Trail Bridge.

33. Is permitting required?

• No, permitting is not required.

34. Please confirm the testing characteristics that are considered for the statistical analysis/PWL pay items?

• All pay items were based on the current drawings. Please see 100% drawing set and refer to schedule of items.

35. Are soil boring reports available? If not, it will be assumed that excavation will be clear of rocks and obstructions.

• Yes, soil boring reports are available and will be provided to the awarded offeror if needed by the designer of record.

36. Do the Superintendent, SSHO and QC Manager need to be 3 separate individuals?

• Per the Technical Approach, contractors are to include in their narrative anticipated contingencies/challenges/risks and strategies for resolving them.

37. No seasonal or in-water work-window restrictions are stated anywhere, despite these being trout-stream crossings in a national forest. Confirm there are no fish-spawning, trout-stream, or nesting-season timing restrictions.

• All NEPA requirements were completed. No in-stream work shall take place on this project. The Contractor shall be strategic in their Technical Approach of addressing how they will cross the creek without affecting the creek floor bed with their mechanized equipment tracks or rubber tires.

38. Mobilization is a single lump-sum item covering all eight non-contiguous sites, but the SOW also says only one site may be active at a time (absent CO approval otherwise). Are partial/repeated mobilization between sites is anticipated and how it should be priced?

• Per the Technical Approach, contractors are to include in their narrative anticipated contingencies/challenges/risks and strategies for resolving them.

39. Is any landscaping restoration required for this project? For example; topsoil, seeding, and fertilizer.

• Yes, please refer to Schedule of Items and 100% drawings, D-111.

40. General Note XIII calls for a "Corrosion Plan… in accordance with Drawing No. D-109," but D-109 is the silt fence detail sheet, not anything corrosion-related. Is this the correct reference sheet?

• Yes, Drawing D-109 is a silt fence detail. General Note XIII should refer to an erosion plan.

41. Please confirm which party, the Forest Service or the Contractor, will be required to carry the cost of the third-party testing agency to verify that the concrete used on site contains the proper mix design and air content between 4% and 7% according to the Contract Drawings.

• Contractor shall be responsible for this requirement.

Schedule

42. When is bat season? This information is helpful regarding scheduling.

• Bat season is March 16th – November 15th.

43. Given the challenging site access, the number of geographically dispersed bridge locations, and seasonal tree clearing and limbing restrictions associated with protected wildlife habitats (including bat species), please advise whether the U.S. Forest Service would consider extending the contract duration. An extension of the project schedule may allow for a more efficient construction approach, reduce the need for accelerated operations, and help minimize the additional costs associated with meeting the current completion requirements. Please clarify whether schedule adjustments will be considered.

• The Government will consider this inquiry during the RFI stage after the requirement has been awarded. All offerors should submit their quotes according to the most recent Schedule of Items posted in the documents section of the sam.gov posting.

44. Can the period of performance be extended after award once the material/equipment lead times are confirmed due to current market conditions for the equipment for this project?

• The Government will consider this inquiry during the RFI stage after the requirement has been awarded. All offerors should submit their quotes according to the most recent Schedule of Items posted in the documents section of the sam.gov posting.

Attachment 2- Statement Of Work

45. The solicitation states Contractors can only work on one bridge at a time. Please confirm.

• In regard to working on different sites simultaneously, please utilize Technical Approach narrative to include anticipated contingencies/challenges/risks and strategies that shall be utilized during the course of this project. The Government reviews the approach to determine if proposed method or plan is acceptable .

46. Per the project phasing requirements on Page 5 of 21 in "C04_Attachment 2 – Statement of Work – CRRD Trail Bridges Phase 2," the document states: "Work at an active trail construction site shall be substantially completed before mobilizing to the next trail site.

Once construction activities begin on a site, the contractor shall make reasonable effort to complete all work at that respective site. In no circumstance shall the contractor begin work at one existing site then move to a new trail site and begin work." Given the accelerated contract duration, difficult site access, the wide spread bridge locations, and seasonal tree clearing/liming restrictions associated with protected wildlife (including bat habitats), constructing the project in a strictly sequential manner may not be feasible.

Please confirm that the Contractor will be permitted to work at multiple sites concurrently and that several, if not all, project locations will be made available at the same time to support the required project schedule. Additionally, please clarify any restrictions on concurrent operations between sites.

• In regard to working on different sites concurrently, please utilize Technical Approach narrative to include anticipated contingencies/challenges/risks and strategies that shall be utilized during the course of this project. Once Forest Service reviews we will confirm if proposed method or plan is acceptable. If permitted, all sites will be made available for full access and operations.

47. Based on the below statements from "C04_Attachment 2 – Statement of Work – CRRD Trail Bridges Phase 2” and discussions from the site visit on 7/28/26, the bidding contractors should assume the LOD from the trial head to the bridge site location is no wider than 4-feet to 4.5-feet and can be assessed by a UTV or equipment of similar width. Please confirm.

• Page 3 of 21: “All additional solicitation trails has an average existing and consistent width of 4-feet to 4.5-feet and can be assessed by a

UTV.”

• Page 1 of 21 note 6: “All specified work shall be confined within the limits of the existing trail traveled way, adjacent ditches, shoulders, cut/fill slopes, and trail embankment stabilizations. Running off the trails will not be allowed on project site and will result into write-up and Notice of Non-Compliance.

• Yes, all trails (except Becky Branch, which is 500-feet in total length and averages 2-feet in width) have an average existing and consistent width of 4-feet to 4.5-feet and can be assessed by a UTV.

48. Per Page 6 of 21 of "C04_Attachment 2 – Statement of Work – CRRD Trail Bridges Phase 2," there is a reference to a "Helicopter Safety Plan (Helicopter Transporting Safety Plan is optional)." Helicopter use was also discussed during the pre-bid site visit on July 28, 2026. Please confirm whether helicopter operations will be permitted for construction activities associated with this project. If permitted, please provide any applicable requirements or restrictions, including:

• Hours or days of operation

• Seasonal restrictions

• Environmental or wildlife-related limitations

• Minimum weather, visibility, or ceiling requirements

• Pilot, aircraft, or contractor qualification requirements

• Flight path, staging, or landing zone restrictions

• Any required permits, approvals, or coordination with local, state, or federal agencies

• Please also clarify whether helicopter use will be considered an acceptable means of access and material transport for all project sites, or if limitations apply to specific locations.

• Per the Technical Approach, contractors are to include in their narrative anticipated contingencies/challenges/risks and strategies for resolving them. The Forest Service will proceed forward from there.

49. The solicitation states anything out of the trail, the Government will issue a notice on noncompliance to the Contractor. Please confirm.

• This is referring to the Statement of Work page 1, bullet 6. This means do not constantly travel outside the trailway regularly as this will result in significant ground disturbance. There is some tree clearing and trail brushing required 4-feet on the uphill and downhill from center of trailway; this work shall result in some work outside of trail but shall include removing tracks/ruts to restore back to initial conditions (refer to 100% drawings, D-110 and D-111).

50. Please provide guidance on the Government’s penalty to the Contractor if a Notice of Non-Compliance is issued to disturbing land outside of the allowable areas adjacent to the trails.

• Responsible party will be cited in writing in areas not adhering to project scope and will be required to perform corrective measures addressing deficiencies in a timely manner as requested by Contracting Officer.

Attachment 3- Lake Russell M.P.2.18 Stakeout Coordinates_12-01-25 and Attachment 5- Lake Russell M.P. 2.18 Trail Bridge_100% Drawings.pdf - Please note, this Trail Bridge was removed from the solicitation and all associated documentation will be removed from the sam.gov.

51. Attachment 3 gives 40 stakeout points for Lake Russell M.P. 2.18 only. Will comparable stakeout data be issued for the other sites?

• The Government will consider this inquiry during the RFI stage after the requirement has been awarded. All offerors should submit their quotes according to the most recent Schedule of Items posted in the documents section of the sam.gov posting.

52. The general notes sheet (G-102) lists Drainage Area, Q100 flood flow, and Freeboard as "N/A," while the profile sheet (C-102) shows an actual "100-yr flood" elevation of

957.37 and a 3-ft freeboard callout. Which is correct?

• Lake Russell Trail Bridge M.P. 2.18 was removed from the solicitation and project in its entirety. Refer to Amendment 1.

53. How will Contractors be able to cross if the water is constantly flowing?

• All NEPA requirements were completed. No in-stream work shall take place on this project. The Contractor shall be strategic in their Technical Approach of addressing how they will cross the creek without affecting the creek floor bed with their mechanized equipment tracks or rubber tires.

54. Are Contractors allowed to divert the waterflow to allow access from one side to the other before the bridge is built? For example, Dam up the creek and pump water around.

• All NEPA requirements were completed. No in-stream work shall take place on this project. The Contractor shall be strategic in their Technical Approach of addressing how they will cross the creek without affecting the creek floor bed with their mechanized equipment tracks or rubber tires.

55. How was the bedrock verified?

• It was verified during surveying efforts.

56. Is access from the other side of the trail allowed?

• Lake Russell Trail Bridge M.P. 2.18 was removed from the solicitation and project in its entirety. Refer to Amendment 1.

57. What is the limitation of vegetation for bridge?

• Site disturbance and clearing shall be limited to the areas where the trail bridge abutment and approaches are constructed, and where construction equipment will be stored or used.

58. Please provide a copy of the Geotechnical Report so that the bidders can verify the density of the rock substrate that we are required to key into at the base of the Lake Russell 2.18 Bridge 24” piers as well as various other abutments.

• After further consideration, the Geotechnical report will not be provided to the public. Please note, Lake Russell Trail Bridge M.P. 2.18 was removed from the solicitation and project in its entirety. Refer to Amendment 1.

59. Lake Russell MP 2.18 Bridge Drawing G-102, Paragraph 3, Note 1 states “…excavation shall be to elevations shown… Unless Bedrock”. Please clarify if there is a rock excavation allowance or how payment will be made for unforeseen rock excavation within the plan dimensions of the foundations.

• Lake Russell Trail Bridge M.P. 2.18 was removed from the solicitation and project in its entirety. Refer to Amendment 1.

60. Lake Russell MP 2.18 Bridge Drawing C-106 Note 14 indicates that all exposed concrete will be stained a color of the Forest Service’s choosing after concrete placement. Does this note apply to all of the other bridges that have exposed concrete? Can you clarify which type of stain is required?

• Lake Russell Trail Bridge M.P. 2.18 was removed from the solicitation and project in its entirety. Refer to Amendment 1.

61. Sheet C-106 on Attachment 5 under the "Timber & Lumber" specifications shows the glulams to be of "Architectural Appearance" where on Sheet G-105 on Attachment 4 calls for "Industrial Appearance Grade" under Section III, Item 6B. Please confirm if both sets of plans can be of the same finish appearance.

• Yes, both sets of plans shall be of the same finish appearance.

62. Attachment 5 for Sheet C-106 under the "Timber & Lumber" specifications says the curb, sills, backing planks, etc. must be Coastal Douglas Fir/Larch. Will a #1 grade Southern Yellow Pine be acceptable here?

• Yes, Number (No.) 1 grade Southern Yellow Pine will be acceptable.

Attachment 4 - Drawings_TS Zeta Multiple Trail Bridges Project

63. Attachment 4 - Sheet G-105 Section III, Item 4 Section states to use A316 SS bolts for wood deck connections. Sheet D-101 states to use 60d (6") ring shank nails. Theseare typically supplied as Hot Dipped Galvanized nails. Will this be acceptable or is therea detail that shows how to use the 316 SS Bolts to fasten the deck planks?

• 60d (6") ring shank nails is acceptable. Screws are preferred due to shank nails backing out over time. For clarity, the posts require the bolts.

64. Attachment 4 - Sheet G-105 Section III, Item 6 Section F states the members shall be pressure treated prior to gluing with an oil borne treatment. Typically, the only treatment type done before gluing is a CCA water based treatment. Oil borne treatment is provided after gluing and sizing of the glulams. Can you confirm oil borne treatment after gluing is acceptable?

• Oil-borne DCOI treatment after gluing is acceptable. Girders shall be manufactured to the exact dimensions shown on the drawings, with all fabrication and drilling completed at the plant prior to treatment to the maximum extent practicable, per AASHTO LRFD Article 8.4.3.1. Treatment shall be to AWPA U1 UC4A retention in accordance with AASHTO M 133 and AITC 109. Each girder shall bear the treatment quality mark and be furnished with treatment certification per AASHTO LRFD Article 8.4.3.3, and with a Certificate of Conformance to ANSI/AITC A190.1 from an accredited inspection and testing agency per AASHTO LRFD Article 8.4.1.2.1. Field cutting of girders is not permitted. Field drilling is limited to bearing shoe connection holes only; all field-drilled holes shall be thoroughly saturated with copper naphthenate field preservative in accordance with AWPA M4 and AASHTO M 133 (per Article 8.4.3.1) prior to installation of hardware.

65. Would a CCA treatment done before gluing and sizing be acceptable for the glulam members? It would be 0.60 CCA and the material is kiln dried after treatment prior to gluing.

• 0.60 pcf CCA treatment of Southern Pine laminations prior to gluing, kiln dried after treatment with mating faces resurfaced prior to glue-up per AITC 109, is approved as an alternate for the laminated girders only. CCA shall not be used for decking, curbs, railings, or any component subject to direct pedestrian contact, per AASHTO LRFD Article 8.4.3.2.

66. Will the pressure-treated materials require WWPI BMP documentation/3rd party inspection?

• Yes. Pressure-treated materials will be provided with WWPI BMP documentation. Third party inspection will be provided if required by the project specifications or the USDAFS.

67. I have not seen the requirement for the glulam materials to be inspected by an independent testing and inspection agency per the 9th bullet under Section III, 6, F on sheet G-105 on Attachment 4. Will that be required? The glulam materials will be supplied by an ANSI certified supplier and will come with the necessary documentation/in house certifications.

• Independent inspection and testing agency certification is required per AASHTO LRFD Article 8.4.1.2.1. No additional or separate inspection beyond the supplier’s standard certification program is necessary. The requirement is satisfied provided that: (1) each glulam member bears the quality mark of an accredited inspection and testing agency (e.g., APA EWS or TP); (2) each member is furnished with a Certificate of Conformance to ANSI/AITC A190.1 issued under that agency’s quality assurance program; and (3) each member is stamped “TOP” at both ends (due to the required cambers). The ANSI-certified supplier’s standard documentation package, as described, meets this requirement.

68. Attachment 4 - Sheet G-105 Section VII, Item 2 states the backwall planks shall be incised and pressure-treated Southern Yellow Pine. Typically, Southern Yellow Pine is not incised prior to treatment. Usually, West Coast species such as Douglas Fir and Larch are incised due to their inability to accept pressure treatment, however SYP doesn't have that issue. Will that be required?

• No. Incising is not required for Southern Yellow Pine. SYP is a readily treatable species and typically achieves the specified preservative penetration without incising. Incising is generally used for refractory species such as Douglas Fir or Larch to improve treatment penetration. Provided the Southern Yellow Pine meets the specified treatment retention and applicable AWPA requirements, non-incised material is acceptable.

69. Attachment 4 - Sheet G-105 Section X, Item 3 for the Timber only says Southern Yellow Pine. Can you provide the grade required for these components listed here?

• Due to the heavy-use of the forest trail bridge supporting hikers, horses, and utility vehicles, No. 1 Southern Yellow Pine (SYP) treated to Heavy Duty Ground Contact (UC4B) or Marine/Foundation (UC4C / UC5) specifications are required.

70. Contract Drawing sheet S-110 describes the requirement for an engineered traffic control plan for a night time lane closure to deliver equipment and material to the Pole Creek trail. Based on the posted speed limit on Highway 76 the drum taper for the lane closure and advanced warning signage will extend into South Carolina. Has this encroachment been discussed with the SCDOT or will the Contractor be responsible for submitting the Tra=ic Control Plan to SCDOT for approval?

• The traffic control plan shall be submitted to the SCDOT for approval.

71. The Contract Drawings refer to multiple different counties that the sites are located

in. Will a building permit be required from any entity other than the USDA/US Forest Service?

• No, a building permit is not required for Federal Lands.

Site- Lake Russell .10 mile

72. What is the extent of demo on the abutment?

• Fully demo and dispose off Forest Service land.

73. Are the Civilian Conservation Corps (CCC) steps required to stay in/remain?

• Yes, the CCC steps are required to stay in/remain. Do not disturb the CCC steps.

Site- Sourwood

74. What is the load rating on the bridge?

• The roadway bridges are rated for HS-20 Loading. In addition, no parking is allowed on the bridges themselves. Contractor shall cross the bridges with a not to exceed HS-20 Loading and the axles must clear the vehicle bridges.

75. What should the Contractor do with trail when tracks appear?

• All mechanized equipment tracks, tire marks and ruts shall be removed. Please refer to 100% drawings, D-111.

76. Should the contractors put back the trail in the exact condition?

• Yes, please restore trailways back to initial conditions.

Site- Becky Branch

77. Is it allowable to widen the trail to get the equipment to the site?

• No, please refer to the 100% drawings, site general notes for each site. There are not to exceed widths for the mechanized equipment to be used.

78. There is a line item for removal of structure that is 7-cubit yard. However, we did not see the structure at the site. Please confirm the structure is still there, or the Government will remove this line item from the requirement.

• Refer to the drawings on Subsheet G-107. Pay Item 20305.B.1 and 20801.B provide the requirements of the 7 CY.
