1 Is the 16x6 able to be changed to a double run of 8x6 per ASTM

C1577.

No, while the conveyance area might be equal, a double barrel CBC does not meet the design intent, especially with regards to debris passage.

2 Is the Concrete Box Culvert going to be redesigned for the depth of cover required in the drawings? Existing specifications indicate a maximum cover of 4 feet vs the design of 10 feet.

The contractor is required to submit shop drawings per Section 602 of the Special Contract Requirements. The wall thickness of the submitted box culvert should be sized appropriate to design earth cover as conveyed in the plans and cross sections.

3 The Substituted paragraphs on page E-12, 108.05 Failure to Complete Work on Time are confusing. If a Winter storm event shuts down the job, are we going to be charged $230.00 / Day until we can go back to work?

If the project enters an approved winter shutdown period after the contract completion date, liquidated damages will be assessed at $230.00 per day.

Under Section 108.05 of the Special Contract Requirements, liquidated damages assessed during an active winter shutdown period are reduced to 10 percent of the full rate specified in FAR Clause 52.211-12.

Once the winter shutdown ends and work resumes, the full liquidated damages rate of $2,300.00 per day will resume until the work is substantially complete.

1 We saw that in the fall creek project that there was a line item with spring bypass/ creek bypass. We have heard from a few contractors that they would like numbers to assist in the bypass. I looked through the plans and was able to locate what CFS the bridge will need to be able to withstand but was unable to locate the CFS the creek is expected to be running at when the project is happening. Do you have any additional information to this, or can you point me in the right direction?

Section 628 specifies a stream diversion for a 2-year peak flow, which is 205 cfs in this case, as shown in the Hydraulic Report Table 4. See Section

628.03 for contractor submittal requirements. A different flow and supporting analysis can be submitted with the contractor's diversion plan. Since this stream is not gaged, CFL cannot make this determination or provide a recommendation.

• Provide the review duration and confirm whether precast fabrication may proceed before wall-design approval.

No further design of the headwalls, wingwalls, cutoff walls, and foundations will be required. Shop drawings of these structures indicating layout of the structures in relation to existing ground conditions will be required. Shop drawing need to be submitted, reviewed, and approved before precast concrete fabrication may commence. The Government review is for general conformance to the plans.

13 Unsuitable Foundation Material and Dewatering at Fall Creek Reference: SCR 102.02A, pages E-1 and E-2; Geotechnical Recommendations Technical Memorandum; Fall Creek plan sheet L.1; Bid Schedule.

Please clarify the required action and payment basis if the Fall Creek box-culvert excavation encounters

Refer to Sections 602 and 209 of the FP and SCRs.

unsuitable material, bedrock or oversized boulders, groundwater, flowing water below the diversion, inadequate bearing conditions, or a need for undercut, stabilization aggregate, lean concrete, geotextile, or revised bedding.

Identify the applicable pay item and confirm whether these conditions will be handled as measured quantity changes, Government-directed extra work, or differing site conditions.

14 Haul Route and Delivery Restrictions Reference: SCR 104.08, page E-3; Bid Item A0440; Summary of Quantities, Sheet B.1.

Please identify the approved access and haul routes for each site and provide all applicable vehicle weight, axle, bridge, width, length, seasonal, permitting, gate-access, turnaround, delivery-hour, and roadway-repair restrictions.

Specifically confirm that the 16-foot-span precast box-culvert sections can be transported to the Fall Creek site using the approved route.

Legal loads are required on all haul routes. County Road 648 which accesses the West Fork Bridge and Hatcher sites has a load limited bridge with a 2-axle limit of 25 tons, a 3-axle limit of 39 tons, and a 4-axle limit of 41 tons.

Some of the roads that provide access to these sites are currently gated and closed. These roads will remain closed to the public during construction.

The Forest will provide the contractor with a key to open the gates and access the sites.

The Fall Creek site is located very near the US 160 highway. The Forest Road accessing the site can accommodate transport of the precast concrete box culvert; however, there are no truck turnaround locations at the project site.

15 RSS Drainage Components and Payment Reference: Hatcher Road plan sheet H.1 / Special 204-A; Bid Item A0300; SCR 207.09, page E-29.

Please confirm the pay item under which the complete Hatcher Road reinforced-soil-slope drainage system is included. Confirm whether geocomposite drains, geotextile, collector and outlet piping, fittings, screens, granular backfill, excavation, and outlet protection are incidental to Bid Item A0300 unless otherwise identified.

Refer to section 207 of the FP for clarification.

16 Reuse Suitability of Excavated Material Reference: SCR 102.02A, pages E-1 and E-2; Geotechnical Recommendations Technical Memorandum; SCR 204.16 and 207.09, page E-29.

On site materials within the construction limits may be reused in the construction of this project provided those materials meet the necessary requirements for the specified material. The Government has not performed any testing to verify the quantity or quality of available material at each site.

Please identify which onsite materials, if any, may be reused as standard embankment, RSS backfill, roadway aggregate, streambed material, general backfill, or riprap bedding/chinking material. Provide available gradation, plasticity, moisture-density, durability, and other testing data.

Confirm that bidders should assume imported material where no approval or test data is provided.

17 Streambed-Material Acceptance Basis Reference: SCR 647.05, page E-39; Summary of Quantities, Sheet B.1; Final Hydraulic Report dated May 28, 2026, identified in

SCR 102.02A.

Please identify the reference location and acceptance criteria for conserved or imported Fall Creek streambed material, including target gradation, maximum particle size, fines content, plasticity, color, angularity, and lithology.

Confirm whether the 45-cubic-yard bid quantity assumes a specific split between conserved and imported material.

Per Section 647 of the SCRs, streambed material will be tested by the contractor to confirm the gradation of existing material. Streambed material can be excavated, conserved, and stockpiled at locations within the construction limits, as identified by the CO. However, because the majority of streambed material at the site was lost in the flood, the contractor should expect to import most, if not all, the required streambed material.

18 Government-Approved Staging and Stockpile Areas Reference: SCR 105.04, pages E-3 and E-4.

Please identify on the plans the previously disturbed areas at each site that are approved for staging, stockpiling, equipment parking, field-office placement, and temporary material processing. For any additional area requiring environmental clearance, identify the review process and expected duration.

All previously disturbed areas at each site (along the road, pullouts, etc.)

can be submitted for use as a staging or stockpile area. No additional environmental clearance is expected for areas that have been previously disturbed.
