Contractor Questions and Answers

Q1. Specification 31 23 00 section 1.2.1 states "All work required in this section shall be measured for payment by the cubic yard of material cut to the design grade, and quantities will be determined by the average end area method as calculated by the Government." This is a commonly used method that can accurately represent quantities for features of work like Embankments or Channels when combined with appropriate centerline alignments and typical design sections however it is not accurate or representative of non-typical features of work using an offset alignment as shown in the solicitation drawings.

The surface to surface method of calculation would be more accurate to better characterize the site and magnitude of work to be performed for excavation/fill.

Will the Government allow volumes of excavation and fill to be generated using the surface to surface calculation method to quantify excavation volumes on this project?

A1. Volume calculations of excavation and fill using surface-to-surface calculation method is acceptable for this contract, as long as the contractor provides data sufficient to make this calculation.

Q2.

Specification 31 11 00 section 3.2.3 states "The CDF-12A site shall be cleared in its entirety to where the outside toe of the dike meets existing ground." After reviewing the solicitation plans and sections no information is provided regarding the location of where the existing dike toe meets original grade.

Is original grade making reference to the EL. +5 that degrading operations specify in 31 23 00? If not please provide a clarification clearing limits that allow Contractors to accurately estimate the quantity of this work.

A2. Limits of all construction activities are intended to be within the exterior toe dike of the project, and shall be determined in the field.

Q3. Specification 01 10 00 section 11(a) states "The rights of entry required for the work to be constructed under this contract within the rights-of-way limits indicated on the drawings, have been obtained by the Government and are provided without cost to the Contractor. The Contractor shall make its own investigations to determine the conditions, restrictions, and difficulties which may be encountered in the transportation of equipment and material to and from the work site. The proposed work, including rights-of-entry as defined by these specifications and as shown on the drawings, is in compliance with all applicable Federal and state environmental laws and regulations."

No contract drawings or specification sections outline the rights-of-way or construction limits for this project. Please provide the right-of-way information for use in preparing bids for this solicitation.

A3. Due to the irregular shape of the dike as a result of multiple lifts, exact coordinates will not be provided. Limits of work will be based on where the exterior toe of the existing dike meets existing ground.

Q4 Specification 01 10 00 section 12(d) states Access corridors where shown on the contract drawings shall be used to access the disposal areas; upland disposal areas where no access corridor is shown on the drawings shall be from the Calcasieu River Main Channel." No contract drawings or specification sections outline the access corridor for this project.

Please confirm that all access to the site shall be from the Calcasieu River for this solicitation.

A4. Confirmed. All access to the site shall be from the Calcasieu River main channel.

Q5. After reviewing the plans and specs, the job proposes sitewide degradation of the placement area, but the proposed and existing cross sections on sheets C-03 and C-04 call for the site to be brought to a final grade of +5.0 NAVO 88. Will the quantities onsite allow for a balance of material, or will import need to be brought in?

A5. The quantities onsite will allow for balance of material.

Q6. Specification Section 31 11 00, Paragraph 3.4 states that debris removed from clearing and grubbing cannot be burned on-site. Will the Government consider allowing clearing debris to be chipped or mulched on-site and evenly spread over the finished surface?

A6. All debris shall be hauled off site as per specifications. General concern is excessive wood chips on site being built into the future embankment section.

Q7. Please provide the Government quantity computation, including the pre-clearing surface/date, design surface, grading limits, cross-section intervals, and assumptions used to establish the estimated 104,000 CY excavation quantity. Please also identify whether the estimate includes dike degradation, interior high-area cuts, corrective grading, and material used to fill low areas.

A7. Analysis of survey data (dated September 2022) indicates that grading the entire site (degrading the existing dikes and interior high-area cuts, and filling in low areas within the side) to an approximate elevation of +5.0' will yield the most level surface. Using a surface-to-surface calculation, results of the cut/fill volumes of the surface at elevations ranging from +4.8' to +5.1' are shown as followed:

Level Volume Above Volume Below

4.80 122,864.3 78,975.4

4.85 117,607.9 86,903.8

4.90 112,675.4 95,156.0

4.95 108,018.6 103,683.9

5.00 103,611.4 112,461.5

5.05 99,472.5 121,507.4

5.10 95,646.0 130,865.7

Q8. Confirm that the original surface used for payment will be the Contractor's Government-accepted post-clearing/pre-grading survey, and that removal of stumps, root balls, organic mat, and other clearing-generated depressions will not reduce compensable excavation quantities. State how isolated stump/root voids are to be treated in the payment surface.

A8. The basis of payment shall be post clearing per specifications and any adjustment for materials lost during grubbing shall be accounted in the bid.

Q9. Confirm whether the design is intended to balance entirely with on-site material. If acceptable soil excavated to design grade is insufficient to raise all low areas to El.

+5.0 NAVD88 within tolerance, identify the required source, quality requirements, measurement, and payment mechanism for imported fill.

A9. The design is intended to balance entirely with on-site material. If in the case the design grade is insufficient, no fill import is required and resultant low spots within the future dike footprint will be addressed in the following contract.

Q10. Identify the approved on-site locations, maximum elevations, slopes, and placement requirements for wasted vegetation, wood, rock, debris, unsuitable soil, or excess soil.

Confirm whether off-site disposal is required when these materials cannot be placed within the grading limits.

Confirm that material placed to correct areas above tolerance is incidental and identify whether rehandling required by Government-directed acceptance corrections is compensable.

A21. Payment is based on the design grade. Material placed to correct areas above tolerance is incidental and rehandling to achieve design grade is not compensable.

Q22. Provide required temporary and final drainage paths, ditch locations/grades, low-point treatment, and ponding criteria. Confirm whether the final El. +5.0 surface is intended to be flat or must receive positive drainage slopes not shown in the cross sections.

A22. There are no temporary or final drainage paths, ditch locations/grades, low-point treatment, and ponding criteria required in this contract. The final surface is intended to be flat.

Q23. Provide GIS/CAD limits for wetlands, protected vegetation, cultural-resource buffers, and other no-disturbance areas. Confirm allowable corridor widths and whether field adjustments can be approved during construction without additional environmental review.

A23. There are no wetlands, protected vegetation, cultural resources, or other no-disturbance areas within the project footprint. Section 01 10 00, paragraph 12(d) allows for corridors to be field-adjusted to minimize impacts to existing wetlands, with the approval of the Contracting Officer. Any major deviation from the limits indicated in the P&S is subject to environmental review and is at the contractor's sole risk and liability (Section 01 10 00, paragraph 11(b)).

Q24. Confirm whether pumping, ditching, sumps, temporary culverts, or discharge of accumulated water is anticipated or permitted. Identify sampling, turbidity, discharge-point, permit, and treatment requirements and whether Government assistance with water-quality monitoring applies to this land-based work.

A24. Pumping, ditching, sumps, temporary culverts, or discharge of accumulated water is not anticipated, as this GDF has not been utilized in years. Water quality monitoring does not apply to this work.

A57. As a phase 1 project, the intent is to degrade and make a flat surface for the next construction phase. Moisture content and compaction for this contract will not be enforced.
