Q.6. Can you clarify the depth of excavation in the existing ponds? It is written as a 6" depth but during the prebid it was said to be a 24" depth?

A. For the excavation of the bottom of Ponds 3 and 4, a min. of 6 inches should be excavated as shown in Attachment 5- Bentonite, The Blanket Method. This may vary as some areas of the pond bottom may need to be over excavated and go deeper than other areas.

Q.7. Can you clarify the type of Bentonite requested, is it powder, granular or is it rolls of bentonite in a GCL application ?

A. Powder or Granular can be used and it is up to the contractor. No rolls. Must be mixed homogenously with the excavated soil from the embankment as shown in the plans.

Q.8. Can you send a detail for the concrete headwall to be used at each new valve location?

A. See Attachment 2 in the Project Manual.

Q.9. Is there compaction testing required for this work? If so does the owner provide this or the contractor?

A. Yes. See page 13 (Testing) of Project Manual. One compaction test will be performed by the

Contractor at a minimum for each pond or every 100 CY of compacted fill. The Contractor is responsible for this work.

Q.10. Will there be BM and survey information given by the Owner?

A. No, Localized control can be established by the contractor/surveyor to verify cubic yardages from each pond.

Q.11. Since there are alternate bid items should there be bid items added for layout, erosion control quality control and dewatering for each alternate ?

A. Erosion Control, Quality Control, and Dewatering has been added to Alternative 1 and 2.

Q.12. Is there a project sign?

A. No.

Q.13. Is the contractor responsible for obtaining any permits?

A. No. WVDNR will be responsible for obtaining the WV DEP Stormwater Permit and will work closely with the Contractor to ensure all rules and regulations are met.

Q.14. Can the owner locate and identify the existing utilities currently buried onsite? If those are broken during the work who pays to repair them if they cannot be located prior to digging?

A. When digging in critical areas, Contractor must get prior authorization before digging in critical areas from Palestine Fish Hatchery Manager, Rodney Null. All utilities will be marked to the best of our ability. If a utility line is broken and prior authorization was given by Rodney then the

WVDNR will be responsible for payment to repair.

Q.15. What is the Engineers estimate for this project?

A. We do not disclose budgets.

Q.16. During the prebid it was discussed that the pond embankment excavation would be 30 feet in width and using the given length of each pond in the base bid and the 30' of width the area is much larger.

example Base Bid item 7 is 13,780 SF using the width discussed and lengths given the disturbance for bid item 7 is 41,340 SF for bid item 7 this in turn increases the amount of bid item 8 from 27560 lbs to 82,680 lbs for Bentonite

May 28, 2024

SECTION 1 - SUMMARY

1. PROJECT

A. Project Name: Palestine State Fish Hatchery Pond Rehabilitation Project

B. Location: Wirt County, 27 Paddlefish Lane, Elizabeth, WV 26143

C. Agency’s Name: West Virginia Division of Natural Resources

D. The project generally consists of the Rehabilitation of the twenty (20) existing ponds on site. Many of the ponds are leaking along the outlet pipe channel and/ or through one side of the embankment. The specific plans to repair each pond are shown per the attached sheets. Ponds leaking through the embankment will use The Mixed Blanket Method for Bentonite Pond Sealant (see Attachment 5).

Ponds No.3 and No.4 leak through the bottom and will use The Blanket Method for Bentonite Pond Sealant. Also, in addition, each pond requires installing a new 10-inch Waterman canal gate valve, anti-seep sand collars, installation/ plumbing of new 10-inch HDPE outlet piping into and from the concrete Catch Basins and then install new HDPE pipe from Catch Basin to the outlet near river.

Most of the ponds discharge into a Catch Basin designed to capture the fish when needed and then discharge into the river via piping. As per the attached sheets, some Catch Basins will require some work to plumb the new HDEP piping into the structure. There are two new 30 ft. X 30 ft. pads that must be constructed as per the attached sheets. Also, in addition there are two existing Catch Basins that have large erosion gullies around the perimeter of the Catch Basin and require fill to be placed around the structure. This project will have a base bid that includes the repair of ponds most critical to the success of the hatchery and two alternative bids for the repair of ponds less important to the operation.

Should damage occur, it will be repaired to the satisfaction of the Engineer at no additional cost to the Owner.

C. GENERAL FILL REQUIREMENTS

1. Soils excavated from the construction areas may be used as fill provided, they are free of organics, comply with these Specifications, and are moisture conditioned to achieve proper compaction.

Fill shall start on a level sub-grade as shown on the Plans. Sliver fills will not be allowed. The sub-grade and fill area shall be dewatered in accordance with these Specifications and shall be firm and approved by the Engineer prior to fill placement. The fill shall be placed and compacted in level lifts in accordance with these Specifications for the applicable fill type. Each fill lift shall be benched and keyed into adjacent slopes as the fill progresses.

The prepared ground surface upon which any fill is to be placed shall be free of all organic materials, shall be uniform and level as possible, and shall be compacted to the satisfaction of the Engineer. No fill shall be placed on frozen or soft/wet ground. Care shall be taken by the Contractor to minimize construction traffic over fill areas in order to minimize the potential for unstable "pumping" conditions to develop in the sub-grade and active fill surface prior to fill placement and compaction. Should the sub-grade or fill become unstable, the Contractor shall remove these materials and re-compact the same to provide a suitable fill surface prior to placement of additional fill as directed by the Engineer at no additional cost to the Owner.

Cohesive Fill: The Contractor shall furnish the labor, material, and equipment necessary to excavate, stockpile, load, haul, spread, and compact cohesive fill necessary to prepare and construct the project complete. Fill materials shall consist of suitable soil generated from excavations onsite. The Contractor is responsible for the placement of fill to the lines, grades, thicknesses, and dimensions as shown on the Design Drawings, or as required by the Engineer.

Material shall be placed and compacted as required for the project as shown on the Design Drawings or as required by the Engineer.

Cohesive fill material must be classified as an ML, MH, CL, or CH in accordance with the Unified Soil Classification System. Soft rock materials will not be allowed for use as cohesive fill. Organic soils and topsoil shall be stockpiled separately from cohesive soil fill. Occasional rock particles with a maximum dimension of 2 inches will be allowed provided the individual rocks are surrounded by a soil matrix and there are no rock clusters. Rock clusters are not allowed. Cohesive fill materials must be sampled and tested by the Contractor and be pre-approved by the Engineer prior to placement as fill.

Testing of Borrow Materials: All needed fill must be attainable on site. Soils obtained on site may need to be modified to meet gradation and moisture requirements. The Contractor shall sample and perform laboratory compaction testing on representative samples of all fill materials obtained from the excavations. The sampling shall be performed under the direction of the Engineer. The testing lab shall also be approved by the Engineer and test results must be submitted to the Engineer for approval a minimum of 15 days before the material is placed as fill. The fill must comply with these Specifications. Minimum testing shall include one (1) each of the following tests for minimum of each pond or 500 CY of material excavated, or when there is a noticeable change in material while work is progressing; Atterberg limits, Natural Moisture Content, and Standard Proctor Compaction (ASTM D- 698).

Fill Placement: The Contractor shall make a reasonable effort to remove roots, limbs, and rocks from the fill material in so much as is practical. No fill shall be placed in standing water, upon frozen earth, and no frozen material shall be placed in any portion of the fill. Material too wet to compact shall be dried prior to compaction and moisture shall be added to materials too dry to compact as required by these Specifications. Sufficient discing equipment and a water truck shall be continuously available at the site and shall be used to manipulate the material to obtain the proper moisture content for compaction. Suitable sheepsfoot and smooth drum vibratory rollers shall be available onsite along with suitable hand compaction or walk behind compactors for tight areas. All compactors shall be approved by the Engineer.

Clods or lumps of material shall be broken down by tractor or other equipment necessary to accomplish this result. Each lift shall extend the full width of the area being filled before starting the next lift. Each layer shall be uniform in thickness and shall be spread and compacted as specified before the next layer is started. Fill which is comprised primarily of rock or rocky soil mixtures shall not be used to bed or backfill new piping.

At the close of each workday, or when work is to be stopped for a period of time, the entire surface of the compacted fill shall be sealed by a method approved by the Engineer. If, after a prolonged rainfall, the top surface of the embankment is too wet and plastic to work properly, the top material shall be removed to expose firm, dry soil. The top material so removed shall be disposed of at the Contractor's expense. The entire surface of any section of fill under construction shall be maintained in such a condition that construction equipment can travel on any part of the section. Ruts in the surface of any layer shall be suitably filled or eliminated by grading before compaction. Care shall be taken to prevent excess travel over any section of the fill to avoid over-compacting that section. Use of rubber-tired vehicles on the fill area is prohibited unless approved by the Engineer. Areas of the fill which are over-compacted or lensed in any way due to traffic or other construction activities shall be scarified to a depth as required by the Engineer prior to placement of additional fill.

Compaction: Complete control of the compaction operation shall be exercised under the direction of the Engineer. Care shall be taken to prevent over-rolling, weaving of equipment, and slickensides in the fill or backfill material. If any portion of the fill is over-compacted, that portion shall be worked with harrow, scarifier or other suitable equipment to a sufficient depth, and the material shall be re-compacted to achieve the desired density. Prior to and during the compaction operation, the material in each layer of fill shall have the best practical moisture content required for compaction purposes;

however, the moisture content shall not be less than 2% below or greater than 7% higher than the optimum moisture content as determined by the moisture/density relationship specified herein. The moisture content shall be uniform throughout the layer. No compaction will be permitted when moisture conditions are such that the required density cannot be obtained.

Compaction requirements are as follows:

Testing: Field density and moisture content tests shall be performed by the Contractor in accordance with these Specifications as approved and directed by Engineer or his representative. Testing shall be performed in accordance with the maximum dry density and optimum moisture criteria developed for the fill material by the standard Proctor test (ASTM D 698) as specified herein.

The Contractor shall furnish a suitable compactor(s) to facilitate fill placement and compaction. Compaction equipment must be approved by the Engineer.

One compaction test will be performed by the Contractor at a minimum for each pond or every 100 CY of compacted fill to ensure 95% Compaction of the embankment side slopes.

D. EROSION AND SEDIMENT CONTROL

1. The Contractor shall provide all labor, equipment, and materials necessary to construct and maintain all sedimentation structures/devices and accumulated sediment as shown on the Design Drawings. The Contractor shall adopt, implement, and comply with the approved erosion control plans and any modifications necessary during construction as required by the regulatory agency, Owner, or the Engineer in order to prevent sedimentation of the stream. The plan shall, as a minimum, include silt fence and stabilized construction entrance(s) (SCE) at locations shown on the Design Drawings and any other measures necessary for implementing erosion control which is satisfactory under all state and federal regulations. The Contractor shall modify erosion and sediment control structures/devices as the work progresses to match changing conditions and prevent sedimentation of the stream. This may include construction of temporary ditches, added rock checks, silt traps, silt bags, wattles, or other measures. The Contractor will be responsible for implementing these measures and complying with all applicable regulations. The Contractor will be responsible for payment of any fines resulting from inadequate erosion and sediment control measures and/ or maintenance of the same. The work shall be performed in general accordance with the West Virginia Division of Environmental Protection Best Management Practice Construction Manual. The recommended erosion and sediment control measures shall be installed prior to any other work. Silt traps and silt fencing must be cleaned out periodically as necessary to ensure proper performance. The Contractor shall maintain the sediment control measures and remove the same after vegetation is established as required by these Specifications. Temporary seed will be applied to all disturbed areas which will not be touched by construction for a period of 7 days or longer.

Temporary seeding will be approved by the Engineer.

DI. SEEDING, FERTILIZING AND MULCHING

1. The Contractor shall furnish the labor, equipment, and materials necessary to place topsoil, fertilize, seed, and mulch all disturbed areas including cut and fill slopes. Seeding, fertilizing, and mulching shall be performed as directed or approved by the Engineer. All disturbed areas will be seeded as soon as possible to minimize erosion. All completed construction areas shall be seeded immediately after completion or as directed by the Engineer.

SEED MIXTURES

The Blanket Method for Bentonite Pond Sealant

This method of applying bentonite pond sealant will be used for the bottom of Ponds No.3 and No.4.

1. The first step of the procedure involves clearing any debris from the surface to be treated such as large rocks, dead vegetation, and roots.

2. Once this has been completed, you must remove 6 inches of soil from what will become the pond’s waterbed.

3. Next, you must use a combination of bentonite and soil to fill in any deep holes, gaps, and crevices along the pond’s surface, in a ratio of 1 part bentonite to 5 parts soil. Once all holes are covered and packed smooth,

4. A layer of bentonite should be applied (at 1 lb/sq.ft.) evenly over the entire waterbed. This should be spread as evenly as possible and smoothed with a sheep roller to incorporate the bentonite into the soil.

5. Finally, the 6 inches of soil that was initially removed should be replaced and compacted with a smooth roller.

6. The pond is now ready to be filled with water. A gentle water flow is recommended to prevent eroding the soil or bentonite layers.

The Mixed Blanket Method for Embankment Construction

This Mixed Blanket Method for Embankment Construction should be used on all Pond Embankments

1. Excavate Pond Embankments as shown in Attachment No. 7.

2. Then mix Bentonite at a rate of 2 lbs/cubic ft. uniformly with the excavated soil.

and then re-construct the pond embankment as shown in Attachement No. 7, compacted in 1 ft. lifts.

3. Then, once the pond embankment has been re-constructed, Bentonite should be applied (sprinkled on surface) at 1 lb/sq. ft. of the side slope surface,wetted with water and then compacted with a smooth roller.

This process will ensure that the soil remains consistent all along the waterbed.

4. The pond is now ready to be filled with water. A gentle water flow is recommended to prevent eroding the soil or bentonite layers.

Attachment 5 Bentonite Application

-Bottom of Pond No. 3 and Pond No.4

-Embankments of Ponds No. 1, 2, 3*, 4*, 5, 6, 10, 11, 12,14, 15, 16, 18, 19, 20, 21, 25, 26, 28, 29, 30.

Note: Ponds No. 3 and No. 4 leak from the bottom and embankment so the Blanket Method must be used for the bottom of the pond and The Mixed Blanket Method for the Embankment of Pond No. 3 and No. 4.

WATERMAN VALVE

C-10 CANAL GATE

C-10 gates offer reliable water control on canal and pipeline systems which operate at low and medium heads. They are built-to-last and designed for years of reliable service, offering a typical field life exceeding 40 years. These gates offer superior performance to “look alike” products and best-in-class construction available only from Waterman.

Typical installations include: farm turnouts, control of industrial wastes, drainage and for tide control.

KEY FEATURES

• Gray iron castings with minimum ¼" thickness.

• Superior rail material assures reliable performance and prevents deflection.

• Bolted steel frame in standard painted steel. Optional upgraded galvanized steel frame, or 304 stainless steel frame.

• Adjustable cast iron wedge blocks feature two machine bolts for dependable seating and water tightness.

• Machine-threaded stem provides ease of operation and extended life, choice of stem thread patterns.

• A solid rim “easy-grip” cast iron handwheel is standard.

• Heavy cast bronze lift nut.

MOUNTING OPTIONS

F = Flatback for wall mounting (typically to a concrete headwall structure).

S = Spigot back for mounting to annular or recor spiral corrugated metal pipe.

CIP = Mounting to PVC plastic pipe with solvent welding (sizes up to 12").

C = Mounting to concrete pipe (gate will be shipped with galvanized steel tapered setting collar).

Type 4 = Mounting to plastic pipe with special two-part epoxy (sizes up to 18").

OPTIONS

• Upgrade frame to galvanized steel.

• Upgrade frame to stainless steel, plus all stainless hardware.

• Upgrade finish to special epoxy, coal tar or total galvanized.

• Waterman Rising-Stem Extensions are factory installed to the height required, providing a rising stem and handwheel, keeping threads and lifts above the water level and allowing the amount of gate opening to be readily determined.

• Non-Rising Stem Extensions position the gate handwheel at convenient static operating elevations, eliminating hardware which might otherwise rise into traffic areas.
