Hopkins County – I-69 Mile point 110.9-111.1 (NB and SB)

Item No. 2-13.00

1. DESCRIPTION

1.1. This work shall consist of grouting portions of an existing underground coal mine along I-69 within the limits shown on the contract documents. The purpose of the grouting is to reduce potential ground settlement and subsidence.

1.2. The Kentucky Standard Specifications for Road and Bridge Construction, current edition, governs unless otherwise specified in this Special Note or in the contract documents. For the purposes of this Special Note, “Department” refers to the Kentucky Department of Highways and/or consultants acting on behalf of the Department of Highways. “Engineer” is defined in Section 101.03 of the

Standard Specifications.

1.3. The method of grouting shall consist of systematically drilling vertical holes into mine locations and injecting grout material to provide bearing support for soil and rock layers beneath the highway facilities.

1.4. Bidders and Contractors shall understand the potential difficulties posed by the nature of the site and the requirements of the work. Parts of the mine may be open, collapsed, silt or muck filled, previously backfilled, or partially backfilled.

Ground settlement during drilling and grouting activities may occur. Difficult drilling, high torque, and hole instability may occur.

1.5. The Engineer, using real-time data provided by the contractor during the drilling and grouting operations, will evaluate and determine the extent of treatment work to be conducted at each location specified in the contract documents.

1.6. Monitoring, recording, and analyzing of drilling and grouting data shall be performed in real time.

1.7. No grouting activities shall be performed from the interior of the mine. The mine space is partially water filled. Several exploratory borings conducted by the

Department were cased and are available for inspection using downhole camera equipment. Video recordings taken by the Department of the borings and mine openings are available for viewing (see section 2 of this note).

1.8. The existing cased exploratory borings are available for the Contractor’s use during construction. At the completion of the grouting activities, grout these exploratory borings to the ground surface.

1.9. Disclaimer. Acceptance of any of the contractor’s submissions required by this note does not constitute endorsement or approval. The acceptance is acknowledgement of the work performed and authorization for the contractor to proceed. The Department is not bound by acceptance of any of the submissions required by this note. Final acceptance will be contingent on the satisfactory completion of the work required by this note.

2. SITE, SUBSURFACE INFORMATION, AND SAMPLE INSPECTION

Bidders are encouraged to consult available geological literature including but not necessarily limited to the Madisonville East Geologic Quadrangle Map (GQ-252).

Additional geotechnical information is presented in contract documents.

Borings advanced using hollow stem augers indicate that the overburden soils vary from 5 to 20 feet in thickness. Rock core specimens obtained in the borings consist of limestone, shales, sandstones and coal as shown in attached project bore logs.

According to geologic mapping the coal seams encountered at the project site are the No. 12 and 11 coal seams within the zone of interest. Geologic mapping and core samples indicates the coal seams can vary from 3 to 9 feet thick and is absent in several locations. Geologic mapping indicates mining activities throughout the project area.

The initial set of exploratory borings (Holes B1 through B6) were performed in August 2025. These borings were obtained using conventional boring techniques (hollow- stem augers, solid-stem augers, and diamond-bit core barrels). Several of the borings where mine openings were encountered were cased through the overburden soil so that a downhole camera could be utilized to view the rock in the borings as well as to view conditions in the mine opening(Borings B-5 and B-6). These borings are assumed to be water filled at this time.

The subsurface data sheets are included in the project documents. The downhole videos of B-5 and B-6 from August 2025 are available for viewing by prospective bidders at the following link:

B5 - https://youtu.be/uOP6rVm6OE4 B6 - https://youtu.be/VKL7vusyb-A

The videos generally show the mine openings to be water filled. In some instances, the videos show a small gap between the top of the water and the mine roof, however subsequent checks with an observation well reader indicate the void is completely water filled at this time.

Additional borings (B-7 through B-11) were performed in March 2026 to further help define the extent of the mined area. These borings were obtained using conventional boring techniques (hollow- stem augers, solid-stem augers, and diamond-bit core barrels). One boring was cased through the overburden soils (B-7).

8.7. Communication System. An appropriate voice communication system shall be maintained between the mixing and pumping location(s) and the drilling and injection locations(s).

9. DETAILED PHILSOPHY, SCOPE, AND DERIVATION OF QUANTITIES

9.1. Philosophy and Scope. Each hole shall be drilled to the elevations of the mine voids/coal seams identified on the contract documents or as identified through exploratory boring. The contractor shall log each hole to identify subsurface materials and voids. Each hole will also be used for grout injection or backfilled as indicated by the Engineer. Casing shall be installed to allow drilling to proceed without loss of drilling flush into the overburden and to maintain an open hole during grouting operations.

The contractor shall submit drill plan to the Engineer for approval prior to any grouting. Drilling plan shall include exploratory holes along north and south bound outer shoulder limits as determined by the engineer. Spacing for exploratory holes should be approximately 20 feet longitudinally along the side of roadway.

Injection holes will be located on pattern determined by the contractor and engineer as site conditions warrant. Spacing of these holes are estimated 20 feet longitudinally with a row along skip line of each lane, inside shoulder of each lane (North and South Bound) and median of interstate. Addition or deletion of holes and/or rows is at the discretion of the Engineer. Thus, monitoring, processing, and interpreting the drilling and grouting data is necessary in real time to avoid delays or interruptions. The Engineer will collaborate with the contractor in reviewing the drilling and grouting data, but will be the final decision-maker for instructing the scope of work. Each hole shall be grouted until refusal, as defined in section 5.5 of this Special Note. Grouting pressure shall ease at the top of rock. The remainder of the hole shall be backfilled with grout to the roadway surface. Holes not encountering voids will be backfilled with grout to the roadway surface.

9.2. Derivation of Quantities. The planned approach to drilling and grouting is uniform and consistent in general philosophy. The foreseen amount and type of drilling and grouting activities are estimated using the current understanding of local subsurface conditions and the treatment area geometry. Estimates of grout are based on treatment of the mine mass as a whole, and not on a hole by hole quantity.

This data and this Special Note represent the current best estimate of the scope of work to be conducted. Modifications to the scope of work at each location will be directed by the Engineer based on the data provided by the Contractor regarding drilling and grouting conditions actually encountered. Addition or

Special Note for Mine Grouting 4/7/2026 Hopkins County, I-69 MP 110.9-111.1 (NB and SB) Page 10 of 13 deletion of holes is at the discretion of the Engineer.

The estimated quantities of drilling and grouting are provided solely for the purpose of providing bidders with an introduction to the scope of the work to be conducted. They are not a guarantee of quantities, absolute or relative, and can reasonably be expected to vary depending on the actual site conditions encountered.

10. EXECUTION OF WORK

Site Drainage Control. Control and properly dispose of drill flush and construction related waste, groundwater, displaced groundwater from mine void grouting, excess grout, and equipment washout water, in accordance with the Standard Specifications, project plans, contract documents and all applicable local codes and regulations. All work shall be done in accordance with EEC regulations. On- site disposal is permitted, with the approval of the

Engineer, with control of solids content to prevent runoff of uncontrolled sediment, grout, etc., directly off of KYTC property. Maintain all pipes or conduits used to control surface water during construction. Repair damage caused by surface water control pipes or conduits from the site. At completion of the work, restore the site to the grades and conditions required by the contract documents and specifications. No direct payment will be made for meeting these requirements.

In addition to any requirements set forth by a health and safety plan required elsewhere in this Special Note, the Contractor shall have no prolonged and significant emission of dust. No direct payment will be made for any expenses incurred by the Contractor for compliance with this requirement except for those items which have been included in the contract as a pay item.

10.2. Drilling. The drilling equipment and methods shall be suitable for drilling through all the conditions to be encountered, and shall be selected and modified, if necessary, by the Contractor. The drilling method shall not cause damage to the adjacent ground, underground mine, or adjacent structures. The

Contractor is to observe the boring during drilling and provide the Engineer a log of all pertinent information.

10.3. Grouting. Once initiated, the Contractor shall methodically proceed to complete all grouting activities in a continuous operation until refusal criteria are met. Areas of excessive grout takes may be required to rest between grouting intervals to control runaway grout. Cost incurred to remove grout from areas outside the work limits shall be borne by the Contractor.
