SCOPE OF WORK

Project Name: CA NP YOSE MULTI(1) Yosemite NP Disaster Supplemental

Project Description/Location. All the anticipated boring locations are within Yosemite National Park. The locations are dispersed throughout the Park as can be seen in the figure below. The purpose of the boring investigation will be to determine pavement and base layer thickness, evaluate subsurface conditions, and collect bulk subgrade soil samples to support project design recommendations. See Figure 1 below.

Figure 1. Yosemite National Park Repair Locations

Scope of Work:

General: The investigative and drilling work is anticipated to take place on or adjacent to roadways in Yosemite National Park. Most roads are paved with 2 to 6 inches of asphalt pavement, but areas with thicker or thinner pavement do exist, and some routes will have

05/29/2026 Amendment A001 segments with no pavement. The drilling sites are accessible for a truck mounted drill rig. The soils beneath the road are believed to primarily consist of silty and clayey sands, sandy gravels, and occasional cobbles. The scope of drilling will include shallow borings (up to 5 feet) and several locations with deeper borings (10 to 20 feet or until refusal). Refer to table below for additional information.

Drilling/Boring Needs & Equipment: Equipment needs include a truck mounted drill rig with an 8 inch outside diameter auger able to advance to 20-foot depths. A two-man drill crew is anticipated. The shallow borings (up to 5-foot depths, but no drilling beyond refusal) are intended to penetrate through the existing pavement structural section and into the underlying subgrade material for the purpose of gathering bulk subgrade samples (~70 lbs. each) and measuring layer depths. The deeper borings (10 to 20 feet) are intended to provide subgrade soil conditions in slide and saturated areas.

Drill cuttings can be dispersed at the site. For the pavement restoration, all borings shall be backfilled with excess cuttings, imported borrow/aggregate, and/or native material and well compacted in 12-to-18-inch lifts. The bore holes within the roadway need to be topped with at least 5 inches of compacted cold patch.

The estimated number of exploration borings and their locations are summarized in the Table below. It is estimated the shallow borings will be on ½ to ¼ mile increments, or as marked. At all locations one or more bulk 70-pound samples are expected to be collected.

Traffic Control: The drilling company is responsible for providing traffic control services during the drilling operations. The road’s two-way ADT will vary depending on location. Expect ADT’s from as low as 100 to 3000+ vehicles per day. Based upon this range of ADT, the traffic control shall include a minimum of two flaggers and two multiple channel 2-way radios. Traffic control equipment, including advanced warning signs, paddles, cones, and other traffic control devices, to be in accordance with the MUTCD.

Working Hours & Wages: It is anticipated that the work will take up to three days to complete, primarily due to the travel time between sites. Drilling work may occur any time from ½ hour before sunrise to ½ hour after dusk. On the days of drilling, meet members of FHWA at a time and location on the route to be designated later.

Davis Bacon wages are not applicable as this is a service contract and not a construction contract.

Other: FHWA will provide personnel on site to determine the locations and depths for each boring sample. FHWA personnel will also log the samples and transport the sample buckets to a shipping location. Utility locates will be coordinated and provided by FHWA in advance. The drilling company may be required to call in duplicate utility locates.

Quote Format: Please provide a quote formatted with the following items.

1. Mobilization/demobilization of drill rig and crew (mileage based).

2. 24 hours for drilling 29 shallow borings and 12 deep borings with 2-person drill crew (at hourly rate).
