Questions and Answers:

Can the tree, shrub, and live stake plantings occur after substantial completion (Spring 2029), or must they be completed before substantial completion (Spring 2028)?

Tree, shrub, and live stake plantings must occur before substantial completion.

If a warranty is required to replace dead or damaged trees, shrubs, and live stakes, are the specified maintenance activities still required?

Yes, specified maintenance activities will be required as needed.

If live stakes cannot be sourced within 25 miles and the State of Kentucky nursery cannot provide the required species or quantities, will an alternate nursery be acceptable?

Yes. As noted in Section 0230 of the Technical Specifications, substitutions may be submitted by the contractor for consideration with ample time for review and response. Appropriate substitutions must be proposed and coordinated with the Engineer and approved at the Engineer’s discretion prior to purchase. Appropriate documentation of changes to the design shall be documented by the contractor and included in the as-built for record.

Will nurseries located in USDA Hardiness Zone 6a be acceptable, subject to species availability?

Yes. However, Kentucky and states bordering Kentucky should be prioritized.

Sources may be submitted by the contractor for consideration with ample time for review and response. Appropriate sources must be proposed and coordinated with the Engineer and approved at the Engineer’s discretion for use, as noted in Sections 0229 and 0231 of the Technical Specifications.

Is the straw mulch shown in the planting details separate from the straw mulch specified for seeding?

No. However, supplementing straw mulch may be necessary during plant establishment and warranty period. Note 27 on the General Notes sheet of the Stamped Plans says 2 tons per acre/ 75% cover and Section 0229 of the Technical Specifications.

The invasive species management plan appears to contain conflicting treatment requirements. The technical specifications call for two applications per year for two years, with a third treatment in denuded areas, while the general notes specify one application before construction, two applications per year before substantial completion, and one application after construction. Could the engineer provide a tentative treatment schedule to clarify the intended sequence?

Treatment of invasive species shall begin promptly after notice to proceed. The first treatment shall occur prior to excavation and tree downing and include areas that will be denuded. A second application shall occur once during construction.

A third and fourth application shall occur post-construction and include denuded areas. Post construction application shall begin by the second dormant season (winter of 2027) for areas completed with equipment work prior to substantial completion. The contractor should consider the number of mobilizations. Between the third and fourth applications that are post-construction, one of them shall be performed during dormant season and one during growing season. The intent for the four treatments is to treat twice in the dormant season and twice in the growing season. Refer to the Invasive Species Management Plan shown on the General Notes sheet of the Stamped Plans. The fourth application completes the Contractor’s obligation and is required for final completion. Additional time may be approved by the Engineer and Owner to accommodate the appropriate season for the fourth treatment application.

If the additive work is performed by a different contractor, who is responsible for treating vegetation in denuded areas?

If the additive alternate is not accepted, then the awarded bidder will be responsible for bringing only clean equipment to the site, minimizing any spread of invasives through mechanical means on site, decompaction of any areas identified for planting that were compacted through construction, and establishing native temporary and permanent ground cover as specified on the drawings and in specifications. Then others would conduct the invasive removal/treatment and woody plantings during construction.

What Container sizes are required for the containerized plantings?

Note 5 on the bottom left corner of Sheet 53 states, “Container Trees shall be 1 gallon or larger in container size and a minimum of 18” tall.”

What are the required height and caliper (or diameter) specifications for the bare-root plantings?

The minimum required height is 12 inches. There are no caliper requirements as long as height requirements are achieved.

What species and quantities are required for the bare-root plantings, containerized plantings, and live stakes?

Quantities of live stakes, containers, and bare-roots per planting area are provided in the tables shown on page 53 of the Stamped Plans. Instructions on determining the number of each bare root and container species within a given planting area are provided as a footnote on the far top right table referring to planting areas on page 53. Full tables including number of each species and planting type (container vs bare root) for each planting area (OC and PC) will be provided to the awarded contractor at the Preconstruction Kickoff for the project.

Quantities of Live Stakes should be calculated based on the measured installation length, the planting density specified in the planting tables (4,840 stems per acre, equivalent to 3-foot spacing), and the number of rows indicated on the Live Stakes Detail in the Stamped Plans.

Please confirm that tree and shrub shelters are not required.

No shelters or cages are required for this project. However, if this additional effort will reduce your costs for warranty replacement, a proposal may be submitted by the contractor for consideration with ample time for review and response. Shelters must be proposed and coordinated with the Engineer and approved at the Engineer’s and Owner’s discretion for use. Appropriate documentation of changes to the design shall be documented by the contractor and included in the as-built for record.

The Pump Around detail on sheet 116 will be used often on the Middle Creek sections and possibly on the smaller sections. Rainfall events would overwhelm the system for the pump around that sized the pumps for typical daily flow. Should we design for a 10-year storm? For smaller channel widths (say less than 5 feet in width) can a bypass channel be dug and utilized for the pump around and reviled when the Channel Construction is Completed?

The pump-around system shall be sized to accommodate base flow conditions and maybe moderate flow in limited circumstances. It is not required to be designed for a 10-year storm event. The primary purpose of the pump-around system, as well as all temporary erosion prevention and sediment control (EPSC) measures, is to minimize erosion within the active construction area, reduce downstream sedimentation, improve constructability, and maintain compliance with applicable state water quality standards.

A temporary diversion channel may be utilized in lieu of a pump around provided the diversion channel is designed and submitted to the Engineer for consideration with ample time for review and response. A diversion must be proposed and coordinated with the Engineer and approved at the Engineer’s discretion for use.

A temporary diversion must be constructed, and maintained to achieve the same objectives of minimizing erosion and sediment transport, protecting water quality, facilitating the planned channel construction activities, and does not disturb trees and areas beyond what is allowed by the permits. Upon completion of channel construction, the temporary diversion channel shall be removed and reclaimed/restored using Fill with Wood in accordance with the contract documents to prevent any potential floodplain erosion or chute cut-offs.

Since the flow rates and pumping costs could vary widely, can this item be listed as an allowance since the expenditures could vary widely?

Pump-around and stream-diversion operations are incidental to the overall Erosion Prevention and Sediment Control (EPSC) work and shall be included within the Lump Sum Base Bid; they will not be established as an allowance or a separate pay item. Much of the need for pump-around activities can be reduced and minimized through construction planning and implementation timing on different flow regimes. Per Section 0209 of the Technical Specifications, the Contractor is responsible for furnishing the correct size and number of pumps required to adequately dewater and isolate each work area, and for determining the location of the impervious dikes for each day's work.

The wetland rehabilitation does not seem to be described anywhere in the documents, can you provide? Is Wetland Enhancement just the notes and additions of Brushwood Sills, etc.

shown on the drawings?

Wetland Rehabilitation work involves the proposed activities shown on the Stamped Plans, including invasive species removal/treatment, installation of structures shown on the plans, native plantings per the planting plan, and limited grading in Wetland C.

Wetland Enhancement work can involve some of what is shown for Wetland Rehabilitation.

Refer to revised wetland plan sheets as attached for proposed activities shown on the Stamped Plans, including limited structure installation, invasive species removal/treatment and native plantings per the plans.

Is Rock excavation a part of the excavated quantities? Please add “ROCK EXCAVATION” per CY and/or “Equipment Rental for Hoe ram” per Month to the list of Unit Prices.

Rock excavation is considered incidental to the construction of the structure and will not be added to the List of Unit Prices. For bidding purposes, the bidders should assume that all boulder sills on the main channel of Middle Creek will need to be keyed into the bedrock approximately 6 inches across the full channel width.

There may be a limited need for structures to be keyed into bedrock on tributaries.

What are the estimated acreages for the stream – livestakes, stream-bareroots, stream container, wetland container (partial canopy), wetland livestakes, and wetland container (open canopy)? These are needed to ensure the correct number of species is included in each area.

Estimates of livestakes, stems and containers have been completed and totals shown in the planting tables. Full tables including number of each species and planting type (container vs bare root) for each planting area (OC and PC) will be provided to the awarded contractor at the Preconstruction Kickoff for the project.

Acreages are provided in the revised quantities.

What are the estimated linear feet of planting of the re-establishment/rehabilitation, intermittent enhancement, and ephemeral enhancement areas? The quantities of live stakes are different on the estimated quantities and the planting table. The linear footage will allow us to create an estimate for what we believe is needed.

The required length of live stake installation shall be determined from the Live Stake lines shown on the Planting Plan Sheets. Quantities should be calculated based on the measured installation length, the planting density specified in the planting tables (4,840 stems per acre, equivalent to 3-foot spacing), and the number of rows indicated on the Live Stakes Detail in the Stamped Plans.

Our revised independent quantity calculations are consistent with what is specified in the Planting Tables. The Quantities Table has been revised to align with the planting tables.

Will there be an ability to sub out a species of bareroot or container?

The species, quantities, and densities shown in the planting tables represent the complete planting design and shall be installed as specified. In the event that specified species are unavailable, the Contractor shall notify the Engineer and provide written documentation of unavailability. Engineer may allow for substitutions on a case-by-case basis, or request that the quantity of unavailable species be proportionally redistributed among the remaining available species within the same planting zone.

Attachment 3 identifies 16,183 live stakes. Drawing Sheet 53 identifies 17,449 streambank live stakes plus 115 wetland live stakes, for a total of 17,564 live stakes. Please confirm the quantity that shall govern Additive Alternate No. 1 for bidding, procurement, installation, and future quantity adjustments.

As a part of this addendum, we have revised the live stake quantity in the Planting Plan. The Quantities Table and Planting Tables have been revised to align with the revised Planting Plan.

Attachment 3 quantifies rock and brush riffles in linear feet; however, the Official Bid Document requests unit prices on an ‘Each’ basis. Please provide the governing number of individual rock riffles and brush riffles for Middle Creek and tributaries, or provide the required method for converting the scheduled LF quantities to Each.

The Stamped Plans identify each individual rock riffle and brush riffle using unique structure callouts and hatch patterns within the proposed plan views.

Bidders should use the Stamped Plans to determine the quantity of structures on an Each basis.

Attachment 3 provides 8,834 LF of total Headwater Treatment. The Official Unit Price Schedule contains separate Headwater Channel items, including a version replacing 7% DGA with 7% Small Wood Chips. Please identify the stationing and/or LF quantity applicable to each headwater treatment/unit-price type.

The Stamped Plans identify each individual headwater channel type using unique structure callouts and hatch patterns within the proposed plan views. The headwater channel detail specifies the composition of each type. Bidders should use the Stamped Plans to determine the length of each headwater channel type and materials needed.

See the revised Headwater Channel detail as attached as well as the revised unit price list that matches the detail.

Several enhancement reaches state that woody debris drop and wood debris vane locations and elevations may be adjusted in the field by the Engineer. Please confirm that the quantities shown in the Contract Documents are the bid basis and that any net increase in the number or extent of structures directed by the Engineer will be handled as a change in the Work.

Quantities shown in the Contract Documents are the bid basis. If additional or reduced structures from what is shown in the Stamped Plans are required by the Engineer, they will be addressed through a Proposal Request from the Engineer and a Construction Change Order, which will be based on unit costs in bid.

Attachment 3 identifies four permanent low-water crossings: one Middle Creek crossing and three tributary crossings. The Official Bid Document provides a unit price for the tributary crossing only. Please confirm whether the Middle Creek crossing is entirely included in the Lump Sum Base Bid and identify the unit-price basis that would apply to additions/deletions or modifications to the Middle Creek crossing.

The Permanent Low Water Crossing on Middle Creek is entirely included in the Lump Sum Base Bid. No additions or deletions of permanent low water crossings on Middle Creek are expected.

Please confirm the acreage to govern bidding and procurement for permanent riparian seeding and wetland seeding. Attachment 3 identifies approximately 21 AC permanent and 2 AC wetland seeding, while Drawing Sheet 53 results in approximately 20.67 AC permanent and 2.31 AC wetland. Also confirm whether the Official Bid Document’s Permanent Seeding with Mulching unit price is intended to apply to both riparian and wetland seed mixes or whether separate pricing is required.

Our independent quantity calculations were simply rounded compared to what is specified on the Planting Tables and in the Stamped Plans. The Quantities Table has been revised to align with the planting tables. Please provide two separate unit prices for permanent riparian seeding and wetland seeding using the attached revised List of Unit Prices.

Please confirm the exact boundary between Base Bid vegetation work and Additive Alternate No. 1. Specifically, confirm that live brush layering associated with wood toe, brush toe, brush riffles, brush runs, and other in-stream structures remains part of the Base Bid, while tree planting, individual live staking, and invasive-species removal/management are included in Additive Alternate No. 1.

The statement provided is correct. Live brush layering, or high-density live staking in-lieu of live brush layering, and additional live stakes around structure sills remain a part of the base bid, as this is a part of the structures. All permanent and temporary seeding, as well as erosion control blanket installation, is also part of the Base Bid. All other tree planting, live staking, and invasive species removal/management are included in Additive Alternate No. 1.

Please reconcile the invasive-species management requirements regarding construction-period and post-construction treatment. Confirm (a) the number of treatment cycles to be included in Additive Alternate No. 1, (b) whether the 68 AC quantity represents acreage per treatment/application or the total measured program quantity, (c) whether the $/AC unit price is per individual treatment or for the complete treatment program, and (d) the date at which Contractor treatment responsibility ends.

For Additive Alternate 1, treatment of invasive species shall begin promptly after notice to proceed. The first treatment shall occur prior to excavation and tree downing and include access paths and areas that will be denuded. A second application shall occur once during construction. A third and fourth application shall occur post-construction and include access paths and denuded areas. Post construction application shall begin by the second dormant season (winter of 2027) for areas completed with equipment work prior to substantial completion.

The contractor should consider the number of mobilizations. Between the third and fourth applications that are post-construction, one of them shall be performed during dormant season and one during growing season. The intent for the four treatments is to treat twice in the dormant season and twice in the growing season. Refer to the Invasive Species Management Plan shown on the General Notes sheet of the Stamped Plans. The fourth treatment application completes the Contractor’s obligation and is required for final completion. Additional time may be approved by the Engineer and Owner to accommodate the appropriate season for the fourth application.

The 68 acres is the estimated acreage of total invasive species treatment area for one application across the full site. The unit price for Invasive Species Treatment is per acre per individual treatment (i.e. the price to treat all the invasive in 1 acre one time. That could include herbaceous spray as well as hack and squirt in the same visit/treatment).

General Note 19 states that in-stream structure bid items include seed, plants, mulch, and erosion-control blanket necessary for construction of the structure. Attachment 3 also provides separate quantities for seeding, ECB, and plantings. Please identify the limits of stabilization considered incidental to each in-stream structure versus quantities to be carried under the separate seeding, ECB, and planting items.

Erosion control blanket, seed, straw, and plantings are considered incidental to the live brush layering structure specifically. This is consistent with the Live Brush Layering detail from the Stamped Plans and Section 0218 of the Technical Specifications. Additional live stakes to be installed around structure sills are also incidental to the structure. The quantities of seeding, straw, erosion control blanket, and plantings shown on Attachment 3 include all other instances.

Attachment 3 identifies 399 SY of non-woven geotextile. Geotextile is also required at various stream structures, low-water crossings, temporary crossings, and construction entrances.

Please provide the intended allocation or clarify which applications are included within the 399 SY quantity and which applications are incidental to their respective structure/access items.

Non-woven geotextile is required for the following structures, Log Vane, Low Water Crossing, Construction Entrance, and Temporary Culvert Low Water Crossing. The 399 SY quantity shown in Attachment 3 only accounts for the permanent structures, Log Vanes and Low Water Crossings. Non-woven geotextile for temporary erosion prevention and sediment control measures will vary based on instances used during construction.

Please provide the intended bid basis for pump-around and stream-diversion operations.

Identify anticipated reaches or number of setups requiring active pumping, the design flow or other criteria to be used for pump sizing, whether continuous/overnight pumping should be anticipated, and whether Engineer-directed pump-around operations beyond the indicated/baseline locations will remain incidental to the Lump Sum Base Bid.

Pump-around and stream-diversion operations are incidental to the overall Erosion Prevention and Sediment Control (EPSC) work and shall be carried within the Lump Sum Base Bid; they will not be established as an allowance or a separate pay item. Per Section 0209 of the Technical Specifications, the Contractor is responsible for furnishing the correct size and number of pumps required to adequately dewater and isolate each work area, and for determining the location of the impervious dikes for each day's work.

The pump-around system shall be sized to accommodate anticipated daily construction conditions, which are expected to be base flow conditions. Flow conditions may vary during construction activities on a reach which may require different pumping capacities, but this will be at the discretion of the Contractor.

The planning and timing of the work can substantially alter the needs related to pump arounds. The primary purpose of the pump-around system, as well as all temporary erosion prevention and sediment control (EPSC) measures, is to minimize erosion within the active construction area, reduce downstream sedimentation, and maintain compliance with applicable state water quality standards. Pumping will not be required overnight if other EPSC measures are in place to minimize erosion within the active construction area while no work is

Please identify the anticipated number and approximate locations of temporary culvert low-water crossings required for construction access. Provide the design/sizing criterion for temporary culvert pipes and clarify whether additional entrance/access-road culverts determined necessary in the field are included in the Lump Sum Base Bid or treated as additional work.

Temporary Culvert Low Water Crossings are intended to be a part of the Erosion Prevention and Sediment Control (EPSC) measures implemented at the

Contractor’s discretion to minimize erosion within the active construction area, reduce downstream sedimentation, and maintain compliance with applicable state water quality standards. Temporary crossings should be used in any streams or tributaries that will be crossed frequently that are smaller than M6. Temporary Crossings are allowed anywhere within the LOD to facilitate construction activities, except on Middle Creek, as noted on the structure detail in the Stamped Plans. It is not advised to use Temporary Culvert Low Water Crossings on reaches M8 or M6 either.

All Temporary Culvert Low Water Crossings are incidental to the overall EPSC work and shall be carried within the Lump Sum Base Bid; they will not be established as an allowance or a separate pay item.

Please provide the anticipated LF and minimum construction width of access-path improvement and relocation required for the project, including any required aggregate surfacing. Sheet 113 notes that no profile was obtained for portions of the relocated access path and that the final alignment will be determined/reviewed in the field. Please identify the pricing baseline bidders should carry.

Access paths shown on overview sheet #3 shall be left in as good or better condition than they are found and shall also be left passable by a truck for KDFWR. No access paths shall remain within the riparian width of the streams and wetlands except at the four specified low water crossings shown on the drawings.

The design does not presently have specific areas of improvement required on the access paths, although the detail is provided for reference if a need is considered during construction, which would be handled through a change order to the project.

Attachment 3 lists 4,059 CY of excavation. Please clarify whether this quantity includes floodplain excavation, specialized channel excavation, structure excavation, existing-channel fill, topsoil stripping/replacement, and other grading shown on the plans. Please also provide any available bid-phase CAD/Civil 3D surfaces, alignment/profile files, or electronic earthwork information so bidders can independently verify the quantity.

The excavation quantity of 4,059 CY as stated in Attachment 3 (and shown as a rounded 4,050 CY on the Grading Plan Overview sheet in the Stamped Plans) is determined by performing a volumes analysis in AutoCAD Civil3D comparing the existing surface to the final proposed surface. This excavation quantity does not account for the over-excavation for structures nor stripping or replacing topsoil.

Electronic CAD files will be provided to the awarded bidder only.

The Contract Documents permit reuse/harvesting of native gravel, logs, rootwads, brush, and other materials where suitable and approved. Please clarify whether the Owner is representing that sufficient approved material exists on site to construct the design quantities.

For bidding purposes, identify which structure materials bidders should assume will require off-site purchase/import versus on-site harvesting/reuse.

At the time of design, it was estimated that sufficient native wood should be available on site to construct all wood structures including logs, rootwads, brush, and wood scraps. Should it be determined during construction that adequate wood is not available on site, the Engineer may issue red-line adjustments to the design to accommodate the amount and size of wood available, provide an area where trees can be thinned on site and used in the construction, or a Construction Change Order may be considered to source the needed wood from off-site.

While the Stamped Plans require harvesting of native rock material for use in the proposed rock structures where suitable and approved by the Engineer, only limited rock is available on various reaches scattered throughout the site. Riffle rock shall be harvested from reaches before installing structures in areas within the limits of disturbance. There is not sufficient rock in the stream reaches to satisfy all structure requirements. Bidders should assume that most rock material, sand, and wood chips will be sourced (purchased and imported) from off-site or quarried from on site, with limited native rock and riffle material in the restored stream reaches harvested and reused on-site.

The drawings indicate that soil borings were not performed and require specific materials such as silty clay for groundwater dams, topsoil replacement, and approved backfill. Please provide all available soil/geotechnical information and clarify the contractual treatment if suitable native/topsoil/silty-clay material is not available in sufficient quantities on site. Should bidders include imported material and associated haul costs in the Base Bid?

No geotechnical soil borings were performed for this project. The available soils information is the NRCS/published mapping summarized in SWPPP (Attachment 1 to the Technical Specifications): the dominant on-site soils are nonhydric Jessup silt loam and Cynthiana flaggy silty clay loam, with Nolin silt loam along portions of Middle Creek. Soils are predominantly silt loams, are native to the location, and contain no anthropogenically altered or urban components. No additional boring logs or laboratory geotechnical data are available for this project.

The design is based on the required earthen materials being obtained from on-site excavation, not imported. Bidders should therefore base the Base Bid on obtaining silty-clay, topsoil, and approved backfill from on-site excavation, consistent with the predominantly silt-loam/silty-clay-loam soils mapped across the site.

Should suitable native silty-clay, topsoil, or approved backfill be determined during construction to be unavailable in sufficient quantity, the Engineer may direct red-line adjustments to accommodate the available on-site material, or the import of material (and associated haul) may be considered as needed through a Construction Change Order.

Please provide a bid-level schedule or anticipated number of required pre- and post-construction soil samples and compaction tests. Also clarify whether subsoiling/decompaction, fertilizer, lime, or other soil amendments subsequently determined necessary by testing are to be included in the Lump Sum Base Bid or compensated as additional work.

The soil sampling and compaction-testing requirements are defined in sections 0205 and 0228 of the Technical Specifications and shall serve as the bid basis.

Testing occurs both pre-construction (prior to any topsoil stripping/excavation, to document existing compaction, texture, and fertility) and post-construction (to confirm disturbed areas are returned to a condition as good or better than pre-construction). Compaction is measured with a handheld penetrometer; soil samples are processed through the University of Kentucky Agricultural Experiment Station/Cooperative Extension Service or other approved testing facilities per AGR-16 and AGR-161.

Bidders should estimate their total sample/test count by applying the frequencies (specified in sections 0205 and 0228 of the Technical Specification) to the disturbed channel length and tributary count shown in the Stamped Plans. All soil sampling and compaction testing is incidental to the Lump Sum Base Bid.

Section 0228 of the Technical Specifications establish a defined performance trigger for decompaction and require that fertilizer, lime, and other soil amendments be applied in accordance with the AGR-16/AGR-161. Subsoiling / decompaction, fertilizer, lime, and amendments items are included in the Lump Sum Base Bid and are not separate/additional work.

Ensuring that topsoil is replaced or regraded on the surface will be very valuable and important for the post-construction testing and long-term success of the vegetation.

Please provide any available asbestos, lead-based paint, hazardous-material, septic, well, underground-storage, or other environmental survey information for structures scheduled for demolition and the existing dump site. Please also identify the estimated dump-site debris quantity/contents, required demolition limits for foundations/slabs, and utility-disconnection requirements. Confirm how unforeseen regulated materials will be handled contractually.

A copy of the Asbestos Containing Materials, Lead-Based Paint & Hazardous Materials Inspection Report (December 8, 2025) is provided with this addendum.

See also Item 55.

Please identify the bid-item/scope classification for all existing culvert removals, toe-drain removals or plugging, and similar drainage abandonment shown throughout the drawings.

Confirm required disposal, backfill, compaction, and restoration requirements.

All culvert removal as identified in the proposed plan sheets of the Stamped Plans shall be considered incidental to the Lump Sum Base Bid. If known, the exact size and length of culverts to be removed are stated in the Stamped Plans. If not stated, then detailed information is unknown and will need to be verified on-site by the Bidder.

All material labeled as ‘To Be Removed’ must be demolished and debris completely removed from the site. All fill placed in abandoned drainage features shall be compacted in accordance with the Technical Specifications to meet in-situ soil conditions and match existing grade, or proposed grade if within proposed grading limits.

Please provide the minimum bid-basis quantities for temporary silt fence, silt bags, temporary gravel silt screens, and other temporary BMPs where no complete project-wide quantity is provided. Confirm whether additional BMPs directed because of field conditions or Engineer preference are incidental to the Lump Sum Erosion & Sediment Control item.

The temporary Erosion Prevention and Sediment Control (EPSC) measures shown on the Stamped Plans and in the project SWPPP (Attachment 1 to the Technical Specifications) represent the minimum required for bidding. Because the SWPPP is performance-based and the actual number, type, and location of BMPs depend on the Contractor's means, methods, and sequencing, no fixed project-wide quantity is established for every temporary BMP; the Contractor is responsible for furnishing, installing, maintaining, and removing all temporary EPSC measures necessary to control erosion and prevent sediment discharge in accordance with Section 0203 of the Technical Specifications and the SWPPP.

Additional or supplemental EPSC measures directed by the Engineer based on field conditions, performance, or Engineer preference are incidental to the overall EPSC work and shall be carried within the Lump Sum Base Bid; they will not be established as an allowance or a separate pay item.

The drawings indicate two construction entrances, while Attachment 3 does not provide a separate entrance quantity. Please confirm two entrances as the Base Bid quantity and provide the required minimum trafficable width, aggregate thickness/limits, and whether existing entrance conditions may be accepted or reused.

There are two primary construction entrances and a third secondary short-term entrance to the site. Construction entrances shall be constructed in accordance with Section 0202 of the Technical Specifications and the structure detail in the Stamped Plans. New installation of a construction entrance may not be required where an existing entrance already meets the structure requirements to clean soil from vehicles leaving the site; in that case the Contractor shall obtain the Engineer's approval before electing not to install a new entrance. New installation will be required on top of the existing gravel where the gravel is small and embedded into the access road with no voids to help clean soil from tires. Access roads and entrances shall be left in as good or better condition at final completion of the work.

Construction entrances are a temporary EPSC measure and are incidental to the overall EPSC work carried within the Lump Sum Base Bid.

Please provide the limits and approximate LF of orange safety fencing/tree-protection fencing required around archaeological sites, significant trees, protected habitat, and other no-disturbance areas. Also clarify whether the cost of any required on-site archaeologist is borne by the Owner or Contractor.

The trees labeled "Do Not Disturb," historical sites, and other no-disturbance areas requiring protection are identified on the Stamped Plans; bidders shall use the Stamped Plans and on-site measurement to determine the extent and linear footage of fencing needed. Trees labeled as Do Not Disturb shall be flagged with orange flagging tape and no equipment shall access within the drip line of the flagged trees. Temporary orange construction fence shall be erected a minimum of 15 feet from and completely around the barn labeled as Do Not Disturb on Sheet

48. Contractor is responsible for measuring and pricing the required fencing accordingly.

Updates to General note #9 have been provided on Sheet 2. No known archaeological sites are on the project site and an Archaeologist is not anticipated to be needed during construction.

Please confirm the required artificial roost tree products and configuration. Drawings indicate each cluster contains three rocket boxes and one BrandenBark structure, while the Official Unit Price description references a ‘Single Rocket Box and metal pole.’ Confirm the required rocket-box type/chamber configuration, pole material, foundations/anchors, and the total procurement quantity for bidding.

Each Artificial Roost Tree (ART) cluster shall consist of four (4) structures: three

(3) Two-Chamber Rocket Boxes and one (1) BrandenBark and shall be constructed and installed per the structure Details on the Stamped Plans and Section 0204 of the Technical Specifications.

The Official Unit Price is for each structure, not each cluster.

Contract Documents contain differing notification periods for Engineer review, including 48-hour and 72-hour requirements. Please confirm the controlling advance-notice period for in-stream structures, finish grading/seeding, live-stake harvesting, material deliveries, and other required inspections. Also confirm that delays resulting from Engineer availability after proper notice will not be charged to the Contractor.

The controlling advance-notice period is 72 hours, as stated on the General Notes Sheet of the Stamped Plans, for constructing any new in-stream structure and for material submittals/deliveries requiring Engineer review (rock, seed, straw, plant stock, erosion control blanket). This 72-hour period governs and supersedes the 48-hour reference in Special Conditions. The 48-hour notices that are specific to tree protection, as stated on the General Notes Sheet of the Stamped Plans and the SWPPP, remain in effect as the minimums for those specific items.

Provided the Contractor gives proper notice, is ready to proceed, and the work item effects a critical path on the schedule, delays caused solely by the Engineer's unavailability will not be charged against contract time.

The Special Conditions require construction to start during calendar year 2026. Please provide the anticipated award and Notice-to-Proceed dates and define the minimum activity that satisfies the requirement to ‘start construction’ in 2026. Confirm whether mobilization, SWPPP/BMP installation, Artificial Roost Tree installation, surveying, or similar preliminary activity satisfies this requirement.

Bid opening is on September 16th. The anticipated intent to award notification is within 30-days from bid opening. Notice-to-Proceed (NTP) will be given once contract documents, contractor permits, and bid bonds are properly executed.

Per Special Conditions, the Contractor is required to start construction in calendar year 2026.

The requirement to start construction in 2026 is satisfied by commencement of on-site physical work under the Contract following NTP, including mobilization, installation of the BMPs, stabilized construction entrance(s), installation of Artificial Roost Trees, and tree clearing. These preliminary activities constitute the beginning of the general order of construction defined in Section 0101 of the Technical Specifications and are sufficient to meet the 2026 start requirement.

Bidders are reminded that the Special Conditions detail work restrictions that directly affect the ability to start and progress work, and the Contractor shall plan and schedule accordingly.

Please identify all permits, applications, fees, inspections, bonds, and road-repair obligations that must be obtained and paid by the Contractor.

The Owner has obtained the USACE Section 404 Permit and the KDOW Section 401 Water Quality Certification. The Contractor shall comply with all provisions and conditions of these permits but is not required to obtain or pay for them. The Contractor is responsible for obtaining the KPDES Notice of Intent.

It is the Contractor’s responsibility to research and obtain all permits, applications, fees, inspections, bonds, and road-repair obligations that must be obtained and paid by the Contractor.

Bonding and insurance requirements are as established in the General Conditions.

Will the project utilize a resident observer (who needs an office trailer)?

No, a Resident Observer and office trailer are not required.

Can a copy of the 401/404 permits be issued to bidders. This will allow us to implement any restrictions/conditions that are part of the permits into our proposal (critical for best price and to avoid changes).

Permit conditions that shall be the responsibility of the contractor are included in the RFB and contract documents. Permit documents will be provided to the awarded bidder and shall be kept on-site.

Can the flow rates for all the streams we are working in be provided since we are responsible for material wash outs up to and including a 100 year flood event?

The Contractor is responsible to warranty that the work has been completed and performed per the described and detailed Stamped Plans, specifications, or red-lines provided during construction by the Engineer. All material sizes and structure details required are provided in the Stamped Plans. The Contractor shall construct the project in strict accordance with the Stamped Plans to minimize any potential rework. The CONTRACTOR shall be responsible for rebuilding any structures experiencing piping, missing chinking, or other deficiencies that will undermine the structure’s long-term stability, prior to the end of the second year following Final Completion.

However, if the Contractor wants to calculate the discharge for a 100-year event for each reach we recommend using the Drainage Area values provided on the Typical Cross-Sections Sheet in the Stamped Plans and regression equations published by Hodgkins, G.A., and Martin, G.R., 2003, Estimating the Magnitude of Peak Flows for Streams in Kentucky for Selected Recurrence Intervals: U.S.

Can the project be awarded if bids are over the engineer’s estimate? If so, by how much?

It is at the OWNER'S discretion to accept or award bids that may be over the engineer's estimate.

Can the prebid sign in sheet be provided to bidders?

The sign-in sheet for the Site Visit meeting has been provided to bidders with this addendum.

After some confusion talking to subcontractors, can the total applications of ISM treatment be clarified… we just need a total number of applications.

A total of 4 complete treatments required across the site. See previous related responses.

Can you provide more specifications for the 54 mounds to be installed on WP-03?

Two (2) clusters of 27 mounds each (54 total) on 15 FT centers for tree planting shall be installed as indicated on the Stamped Plans (noted on revised Sheets 57 and 16). This construction activity includes scraping the top layer of soil within the limits of disturbance associated with Wetland C (WP-03). Scoop with an excavator bucket to create each mound, approximately 2 FT tall by 3 FT wide, to be loose dumped next to the excavated pit. Each mound should be large enough to plant a single container tree in the grid pattern shown on Detail 01 of Sheet 53.

Does the mulch need to be anchored? (tracked in, crimped, tacked, etc.)

Mulch will need to be installed beneath erosion control blanket in all areas that receive erosion control blanket. Mulch in areas outside of erosion control blanket application do not have any anchoring requirements.

Can soil testing be done in-house, or do we need a subcontractor?

For soil chemistry and nutrient testing, the Contractor may collect the samples but must submit them to the UK Agricultural Experiment Station / Cooperative Extension Service (or an equivalent facility approved by the Engineer) for processing as specified in Sections 0205 and 0228 of the Technical Specifications.

For compaction testing, the Contractor may perform in the field and report to the Engineer as specified in Sections 0205 and 0228 of the Technical Specifications.

Is the “twice seed rate” on live brush layering structures accounted for in the permanent seed acreage in the plan set?

No, the supplemental seeding is considered incidental to construction of the Live Brush Layering structure and is not accounted for in the acreages reported in the Planting Tables.

Have asbestos and lead assessments been performed on the structures to be demolished?

Refer to Item 36.

Can you provide success criteria for the invasive species treatment portion of work?

The invasive species treatment under this Contract is a performance-of-work (treatment) obligation (quality work), not a numeric establishment/success-criteria obligation. The Contractor's responsibility and the basis for acceptance are defined in Section 0232 of the Technical Specifications and within the General Notes Sheet and Planting Plans Sheets on the Stamped Plans.
