PART 1 GENERAL

1.1 SCOPE

This section contains weather and water stage data for construction at Rough River Lake Dam. Rough River Dam is intended for flood control therefore the pool and tailwater will fluctuate based on rainfall, inflows into the reservoir, reservoir levels, and downstream channel conditions. In spring of 2023 a pool restriction was implemented at the project. The "Normal Summer Pool" of 495 NGVD29 was lowered implementing a "Restricted Summer Pool" of 490 NGVD29. The Restricted Summer Pool will be the summer pool target elevation for work completed on the outlet works and cutoff wall. When the general term "Summer Pool" is used in this Contract, the Restricted Summer Pool of 490 NGVD29 is inferred. The Normal Summer Pool may be re-instated after acceptance of the outlet works AND cutoff wall.

The winter pool targets a pool of 470 NGVD29 in the winter.

The Geotechnical Interpretive Report (GIR), available in Volume 6 of the technical package, includes both the target pools listed on the Seasonal Guide Curve for the months when the summer pool and winter pools are targeted. The GIR also includes the Stage Frequency Curves which provide a summary of the probability to exceed any given reservoir stage in a given year. Hydrographs for the reservoir and the tailwater are included in the Volume 1 Plans with additional electronic resources included herein. This information is provided to the Contractor for review and interpretation to understand how the reservoir levels vary and how best to sequence work at the project. Reference is made to Specification 01 11 00 SUMMARY OF WORK for an overview of the project.

1.1.1 Water Control Advisory Panel (W.C.A.P.)Coordination

A Water-Control Assessment Panel (W.C.A.P.) will be formed from the USACE Louisville District Personnel and representatives for the Contractor. The W.C.A.P. will include the Dam Safety Modification Lead Engineer, The Project Manager, The Dam Safety Program Manager (DSPM), Water Management Team Lead, Resident Engineer, the Lake Manager, Contractor's SSHO, and the Contractor's QC Manager. The W.C.A.P. will convene at regular intervals when the reservoir is approaching the 510 elevation to make assessments of the current ongoing work and the impacts that the projected weather forecast may have for the dam. During construction, the W.C.A.P. will make recommendations to the Contracting Officer whether to proceed with work, to complete elements that have already started, to abandon elements that have already been started, and to recommend additional emergency measures related to pool levels as required to maintain Dam Safety during construction activities. Dam Safety and the integrity of the dam shall remain the number one priority for the project during construction.

The Water-Control Assessment Panel (W.C.A.P.) will also convene and make recommendations regarding evacuation of the spillway that may be utilized by the Contractor as a haul route. The concrete spillway control sill shall be protected from damage during hauling operations. If the reservoir rises to a high pool scenario that will likely result in uncontrolled spillway

DOCUMENT 00 31 19.23 06 Page 3 flow, the Contractor must remove any haul road material to below the concrete sill elevation (524), and any noticeable damage to the sill repaired by the Contractor within 36 hours.

Any work required to access the stilling basin and discharge conduit outlet works functioning as the primary means of flow conveyance must not disrupt normal releases more than 8 consecutive hours at any given time. This includes the time to dewater and the mobilization/demobilization of any equipment or personnel entering the structure. The Contractor is responsible for handling dewatering activities from sandbagging or cofferdams, gate leakage, or other sources as required to complete operations at normal or elevated pools. Following periods of shutdown or at the discretion of the Contracting Officer, the outlet works shall be cleared of any obstructions to allow controlled releases by USACE.

If a shutdown of releases from the project lasting more than 8 continuous hours is required at any time, USACE shall be notified in writing at least 7 days in advance and the contractor shall provide means for a continuous water bypass of at least 50 cfs. This may be accomplished through stilling basin dewatering, pumping of gate leakage, pumping from the reservoir, or any combination of these alternatives. The design and operation of the bypass system is the responsibility of the Contractor and shall be submitted to the Government for approval as part of the work plan.

The new outlet works shall be fully functioning, been placed in service a minimum of 30 days, and re-inspected by the Government for approval prior to abandoning the existing conduit or initiating work in Critical Area A.

Any time the stilling basin or tailwater is dewatered for either outlet works structure, the Contractor shall be responsible for removing fish from the tailwater and stilling basin for relocation downstream of any required cofferdam for dewatering. When dewatering of a stilling basin occurs, the Contactor shall coordinate with the Kentucky Department of Fish & Wildlife a minimum of 14 calendar days in advance, for approval and supervision of fish removal. Dewatering will not be allowed to occur without prior approval from the KY Department of Fish and Wildlife and a representative from said agency present during relocation operations. This dewatering requirement shall not apply to the new stilling basin should it be submerged by high water prior to being connected to the new retreat channel. No separate payment will be made for removal and relocation of fish.

1.1.2 Anticipated High Water And Unusually Severe Weather

Unusually Severe Weather Days are evaluated in accordance with Specification 00 80 00.00 06, paragraph 1.20, TIME EXTENSIONS FOR UNUSUALLY SEVERE WEATHER. In order to qualify for an Unusually Severe Weather Day related to high water, the following criteria must be met in addition to the requirements of Specification 00 80 00.00 06:

Control Tower: Work must cease in the area protected by the Cofferdam when the reservoir reaches elevation 521. The reserovoir rate of rise will vary based on rainfall. The Contractor must be prepared to remove all personnel, equipment, and materials from the area within a period of 48 hours of the reservoir surpassing the 510 elevation during an extreme event.

Cutoff Wall Construction on the Dam: Cutoff Wall excavation and grouting activities in the designated critical areas must cease when the reservoir reaches elevation 510. See special requirements contained herein relative to the cutoff wall.

DOCUMENT 00 31 19.23 06 Page 4

Stilling Basin Construction: Work in the protected area must cease when the tailwater reaches an elevation of 450. The Contractor must be prepared to remove all personnel, equipment, and materials from the area within a period of 48 hours of the reservoir surpassing the 445 elevation or a projected spillway flow event.

Spillway Haul Road: The upstream spillway haul road will be flooded prior to reaching the 521 elevation. No sandbagging, barricades, or other means of maintaining spillway haul road access are permitted and operations on the spillway haul road must stop when the road is covered by water.

Requirements for restoring the spillway prior to a flood event are contained herein and in the Volume 1 Plans. Aggregate surfacing for the haul road within the spillway above the 524 elevation must be 3 inch sized aggregate or smaller.

The Contractor must assume that two (2) high water events are expected to impact the project during construction exceeding the thresholds defined above. Each singular high water event is anticipated to impact all scenarios listed above as part of the that flood event. All demobilization from flooded areas, preparatory work, clean-up, and remobilization are incidental to GENERAL MOBILIZATION AND DEMOBILIZATION. In no instance will payment be made for time expended between normally required set-up, for delayed production due to concrete curing times, and the time required for equipment movements. This item does not include scheduled drawdowns of the reservoir as detailed in the plans and specifications or curing times associated with concrete. Links to hydraulic, meteorological, and hydrographs are provided herein with additional hydrographs provided in the Volume 1 Plans.

1.3 WORK RESTRICTIONS ASSOCIATED WITH POOL LEVEL

Work shall be restricted based on pool level and calendar as described herein. The below criteria may be revised by the Contracting Officer, upon recommendation from the W.C.A.P., after completion of demonstration areas and test sections to more accurately reflect construction sequences, scheduled time of completion, and the calendar year to occur:

a. Outlet Works Construction: Releases during this phase shall be controlled by the existing outlet works. The Contractor shall construct a cofferdam to Elevation 525 with a controlled overtopping zone 50 feet long at Elevation 524 along the left cofferdam abutment.

At reservoir Elevation 510, the W.C.A.P. and Contractor Site Safety Health Officer (SSHO) shall convene to assess reservoir loading, seasonal uncertainty, cofferdam performance, spillway evacuation, and upcoming weather forecasts to determine if working conditions are safe to proceed. At pools above 510 the Contractor shall provide at least 1 dedicated individual to monitor performance of the Cofferdam 24 hours per day until a history of satisfactory performance is obtained, or at any point personnel, equipment, and completed work are threatened by cofferdam performance issues such as slope instability, sandboils, or embankment cracking. Above Elevation 515 the W.C.A.P. must meet at least bi-weekly, or as needed, to assess risks for any potential spillway flow event.

Additionally, blasting operations shall cease within 250 feet of the Control tower cofferdam when the reservoir exceeds Elevation 515.

Exceptions may be granted from the Contracting Officer in writing for instances where no personnel, equipment, or permanent work are placed at risk from potential inundation of the excavation. At a reservoir level of 521, or upon the direction of the Contracting Officer or SSHO, no personnel are permitted to enter the control tower excavation behind the cofferdam. The Contractor must remove all personnel, equipment, and materials from the protected area if reservoir levels are projected to reach an elevation of 521.

In the stilling basin and for the tunnel, all work in the area must be evacuated by the time the tailwater reaches the 450 elevation. The W.C.A.P. may recommend ceasing work sooner based on weather forecasts and the amount of seepage entering the excavation.

b. Underwater Excavation: See Specification Section 31 23 05.00 06 MASS EXCAVATION paragraphs for measurement and payment for underwater reservoir level limitations specific to underwater dredging/excavation and underwater blasting. Note that blasting within 25 feet of water shall only be conducted when the reservoir is below elevation 490.

DOCUMENT 00 31 19.23 06 Page 6

Gradual drawdown of the reservoir normally begins on 15 October and is scheduled for completion to an elevation of 470 on 1 December. The rate of drawdown is dependent on rainfall and inflow conditions. There are years in the historical record where heavy rainfall prevented the drawdown for the reservoir from reaching winter pool. On any given year requiring underwater blasting, the Contractor can request that the maximum drawdown rate be initiated on October 1st. The maximum amount the reservoir can be drawn down is 0.75 feet per day and is contingent upon rainfall and project inflows. Submit requests in writing to the Contracting Officer at least 120 days in advance. Submitting a request is no guarantee that such request will be approved by the Contracting Officer. In the event of heavy rains, the reservoir can rise very quickly. The Contractor is solely responsible for planning and sequencing the operation around reservoir fluctuations. Appropriate length spuds, evacuation plans, temporary mooring to allow for significant pool rise, and proper planning/sequences of work based on available weather forecasts are required.

c. Upstream Cofferdam Construction and Grout Curtain: The Stage 1 cofferdam allows for construction of the main cofferdam and required foundation treatment to occur in the dry. The Contractor may request an early drawdown beginning on September 1 on any given year but such request must be received in writing by the Contracting Officer at least 120 days in advance. Requests will be accepted or rejected by the Contracting Officer within 45 days of receiving the request.

d. Existing Conduit Abandonment: After the new outlet works has been in operation for 30 days, re-inspected, and formally approved by the Government,the W.C.A.P. shall convene to assess reservoir loading, seasonal uncertainty, and upcoming weather forecasts to determine when the existing conduit abandonment may proceed. The work shall be sequenced to occur during a time period where minimum releases from the new outlet works shall not result in reservoir levels above 515 or associated releases will not flood the Contractor's downstream operation at the stilling basin. Prior to approval of the new outlet works, the Contractor may elect to sandbag the existing stilling basin end sill up to elevation 438 and remove any fish trapped in the existing stilling basin. Alternative methods for earth or steel cofferdams must be approved by the Contracting Officer at least 30 days in advance. After approval of the new outlet works, the Contractor must execute procedures to abandon the existing outlet works detailed on Contract Drawings CTW-CG-502 through CTW-CG-506. The Contractor shall be responsible for evacuating the conduit/stilling basin of all manpower, equipment, and materials in a timely manner in the event heavy rainfall occurs with the potential to overtop the downstream cofferdam. Additionally, the Contracting Officer may direct evacuation of all personnel, materials, and equipment from the conduit and stilling basin upon recommendation from the W.C.A.P.

e. Cut-off Wall Critical Area A from Station 22+40 to Station 22+70 - Work related to excavation at the conduit, demolition of the conduit, and severing the conduit shall not be initiated if there is high water or forecasts for high water at the reservoir. The reservoir must be drawn down to a minimum pool of 500 before work will be permitted to proceed by the Government. Historically, the months of July through December have proven to have less fluctuations compared to the months of January through June. To avoid risks of high water during construction, work associated with placement of the Special Panel/Secants shall occur in continuous shifts until completion. If

DOCUMENT 00 31 19.23 06 Page 7 necessary, the Contracting Officer may halt operations and direct emergency backfilling procedures upon recommendation from the W.C.A.P.

f. Cut-off wall construction in critical areas: The W.C.A.P. will advise the Contracting Officer as to whether to proceed with the current element(s) under construction or to abandon the element(s) by placing low strength concrete or by adding cement to the slurry with the intention of returning to the element and reworking the area. No new excavations shall begin at pools above 510 without approval from the Contracting Officer.

g. Retreat Channel Construction: Rough River is a flood control reservoir with releases from the reservoir into the tailwater area governed by inflows into the reservoir, reservoir levels, and downstream channel conditions. The Government is not permitted to deviate from authorized operations. The outlet works alignment between Stations 25+30 and 30+70 must contend with fluctuating tailwater levels while allowing for continued operation of the flood control project.

The area between approximate Stations 25+30 to 27+00 supports the existing stilling basin access road. This area must be excavated last and cannot be removed until alternative access roads to the existing stilling basin are provided for USACE Staff. The area between Stations 27+00 and 30+70 is located within the existing retreat channel that is required to remain functional for the existing outlet works to make releases. The area between Station 25+30 and 30+70 has special restrictions and requirements that must be followed as indicated in specification 31 23 05.00 06 MASS EXCAVATION. The Contractor must submit written notification to the Contracting Officer at least 45 days in advance for intent to complete the tailwater work for any given phase so that coordination with W.C.A.P. can be established. For worker safety, no work must be permitted if releases exceed 1,600 cfs or the tailwater pool exceeds an elevation of 439.5.

The Contractor can access the Daily Lake Report at https://www.lrl-wc.usace.army.mil/reports/lkreport.html.

The area between Stations 27+00 and 30+70 is best completed during the summer months (July-September)which greatly reduces risks for high water but is no guarantee to the Contractor that favorable conditions will exist during this period. Work stoppages related to high tailwater or high releases do not constitute a delay by the Government. The work must be completed at any point before the control tower, tunnel, and stilling basin are fully functional. Therefore multiple working seasons exist to perform the work during optimal weather conditions and off the critical path schedule.

1.4 HYDROLOGIC CONDITIONS

The reservoir elevation varies throughout the year. The yearly Rough River Lake Report from 1983 to 2024 is available at the following website:

https://www.lrl-wc.usace.army.mil/reports/yearly/Rough%20River%20Lake.html.

Typicall, elevation 442 (or stage 42 per the USGS datum) at the end sill is only surpassed as the result of high releases from the reservoir, not from back flooding downstream. Information for the tailwater stage data from 1999 to 2024 is available at the following link:

https://waterdata.usgs.gov/ky/nwis/uv/?site_no=03318010&PARAmeter_cd=00065,00060.

Monthly tailwater hydrogrpahs from 1983 to 2024 are contained in the Volume 1 Plans. Hydrographs detailing the relationship between the pool, tailwater, and rainfall are also included in the Volume 1 plans. A stage

SUBSURFACE INVESTIGATION INFORMATION

08/24

PART 1 GENERAL

1.1 GEOTECHNICAL DOCUMENTS PROVIDED

Subsurface exploratory borings have been obtained by the Government to determine the general character of the subsurface materials within the project area. During 2018 and 2019 a subsurface investigation was conducted in support of the outlet works construction consisting of 39 borings advanced in soil and/or bedrock and 13 test pits advanced in soil. The subsurface investigation techniques included augering soil with hollow-stem augers, soil samples obtained via standard penetration testing and undisturbed sampling methods, rock drilling using rotary diamond core tooling, down-hole televiewer surveys, logged rock core, and specific soil and rock testing. The boring location plans and boring logs are included in the Volume 1 Plans. Boring logs and subsurface information for the exploration is generally located in the Geotechnical Interpretive Report (GIR). Information specific to tunnels is included in the Geotechnical Baseline Report (GBR) and Geotechnical Data Report (GDR).

Project specific subsurface information including previous investigations, previous construction activities, previous laboratory test results and boring logs are included For Information Only (FIO) in the GIR contained in Volume 6 of the Contract Documents. The GIR Appendix includes a comprehensive set of boring locations plans along with an index of previous investigations, borings, and locations. While the borings are generally representative of subsurface conditions at their respective locations, localized variations of characteristics of the subsurface materials should be anticipated. Groundwater elevations, shown on the boring logs, are those encountered at the time when the borings were taken and will fluctuate due to factors such as rainfall, lake, and/or river stages.

The Phase IB Exploratory Drilling and Grouting Construction Completion Report is also included in Volume 6 For Information Only (FIO). The Phase IB Boring and televiewer logs are made available in a stand-alone document also in Volume 6: Phase IB Boring Logs. The Government assumes no responsibility for any interpretations made by the Contractor from FIO boring logs, data, or reports.

The tunnel specific Geotechnical Baseline Report (GBR) is a contractual document contained in Volume 5 of the Contract Documents. The GBR provides design data and other key information that shall be the basis of the Contractor's bid for the tunnel. The Geotechnical Data Report (GDR) contains tunnel specific subsurface information data, including boring logs and laboratory testing, that is the basis of the GBR interpretations and is also available in Volume 5 of the Contract Package.

1.1.1 Contractor Required Investigations

Any noted concrete repairs that were required as part of Section 03 70 00 MASS CONCRETE, Section 03 30 00, CAST-IN-PLACE CONCRETE OUTLET WORKS, or Section 31 73 00 TUNNEL GROUTING must be fully inspected and evaluated prior to placing the outlet works into service. Cracked or spalled areas may require additional repairs by the Contractor before the outlet works is placed into service. The cost required concrete repairs is the responsibility of the Contractor.

7. Written acceptance for the Pre-Operational Inspection will be provided from the Contracting Officer.

8. The Contractor is responsible for facilitating and maintaining safe access to all required locations in accordance with EM 385-1-1 including air monitoring, fall protection, and confined space entry.

b2. 30-Day Operability Demonstration.

Once the structure is deemed operable by the Contracting Officer, the new outlet works shall be placed into service to demonstrate performance for a period of 30 days. The Contractor will maintain ownership of equipment (mechanical, electrical, and hydraulic) during this operational demonstration period. During this period, Louisville District Operations personnel shall be required to make gate operations to regulate the reservoir. The Contractor and Government Construction personnel shall accompany LRL Operations in the Control Tower for required gate operations to regulate the reservoir, or any other routine Dam Safety activity. Such requirements during the 30 day operability period shall be coordinated between LRL Operations, LRL Construction, and the Contractor through the Water Control Advisory Panel. The Contractor shall furnish all utilities, including lighting and electrical power,during this operability period at no additional cost to the Government. At the completion of the demonstration period the outlet works will be inspected per the requirements of Section b3.
