Project Location and Type of Work – Western Federal Lands Highway Division (WFLHD) intends to solicit and award multiple Blanket Purchase Agreement(BPA) for Geotechnical Drilling Services.

The Contractor must furnish a drill crew consisting of at least one journeyman-level drill operator and one experienced drill helper. Additional qualifications may be included in the SOW. In addition, the SOW may indicate the need for traffic control flaggers. The Contractor is responsible under this agreement for the control, management, and supervision of the day-to-day activities and performance of their employees and subcontractors while performing the services required by the agreement. Services to be delivered under this agreement by the Contractor to the Government are non-personal as defined by FAR Part 37.

Work will consist mainly of geotechnical drilling.

This agreement primarily covers the following geographical area: the states of Alaska, Oregon, Washington, Idaho, Montana; and Yellowstone National Park and Grand Teton National Park in

Wyoming. Occasionally, work in other states and locations may be requested. The Service Contract Act statute will be applicable. The actual work location will be designated within each Statement of Work.

Work may consist of the following:

DRILLING

• Soil Sampling - The Contractor must conduct standard penetration sampling in accordance with standard methods specified by the American Society for Testing and Materials (ASTM) in ASTM

D 1586-84, Standard Test Method for Penetration Test and Split-Barrel Sampling of Soils.

Standard penetration tests (SPT) and split-barrel sampling must be conducted in soil, as determined by the SOW.

• Core Drilling and Sampling - If drilling and/or SPT refusal occurs, as determined by the Field

Inspector, the Contractor will begin core drilling. Coring may be performed in all fresh, broken, and/or weathered rock, providing continuous core samples of the materials being investigated.

Pavement cores must be drilled through the entire thickness of pavement present in the roadway, up to a maximum of 12- inches. Core samples must be recovered in as intact a state as possible at the locations and to the depths prescribed in the SOW.

• Subgrade Sampling - The COR will determine the frequency of subgrade sampling and/or select specific sampling locations in the SOW. Sampling must begin by carefully augering through the pavement, if present, without disturbing the underlying base course, and hand excavating the pavement material to the top of the base coarse.

• Groundwater Level Sampling - Provide a water bailer or pump and an electronic water level meter capable of measuring the depth to groundwater to 1/100 of a foot, unless stated otherwise in the SOW.

• Other Sampling - Other sampling methods, such as Osterberg sampling, pitcher barrel sampling, direct push, grab sampling, or other sampling may be specified in the SOW.

INSTALLATIONS

• Slotted and Solid Piezometer - When required in the SOW, the Contractor must install a PVC standpipe piezometer to the depth as directed by the COR or field inspector.

• Inclinometers - When required in the SOW, the Contractor must install flush coupled, ABS plastic inclinometer casing

• Vibrating Wire Piezotmeter Installation - When required in the SOW, grout the Vibrating Wire

Piezometers (VWPs) into the boreholes following the manufacturers recommendations. Install

VWPs at the depth as directed by the COR or Field Inspector.

• Sondex - When required in the SOW, the Contractor must furnish a 3-inch Sondex pipe

(corrugated plastic pipe used for drains), Sondex pipe couplings, Sondex sensing rings, strong cable ties (16 inches or longer) or wire, mastic tape, and vinyl tape

• Thermistors - Install 1-inch diameter PVC water pipe with threaded couplings for the thermistor string. Ensure the end cap and all connections are water tight.

• Other Installations - Other installations, such as thermistors, trolls, spectral acceleration arrays

(SAA), time- domain reflectometer (TDR), strain gauges, load cells, thermometers, barometers, rain gauges, cameras, or other installations and instrumentation may be specified in the SOW.

Instrumentation installations may also include above and/or below ground wiring and remote communication equipment installation, including cell phone and satellite phone communication systems with battery and/or photovoltaic power sources.

IN-SITU TESTING

• Downhole testing such as vane shear testing, pressure meter testing, dilatometer testing, packer testing, dynamic cone penetrometer, temperature, multigas meter, and other methods may be specified in the SOW.

GEOPHYSICAL AND MOM-DESTRUCTIVE TESTING

• Geophysical testing such as surface seismic refraction and/or reflection, refraction microtremor

(ReMi) testing, multichannel analysis of surface waves (MASW) testing, electrical resistivity, magnetics, ground penetrating radar (GPR), and downhole boring optical and acoustic imaging, downhole and crosshole seismic testing methods may be specified in the SOW.

FIELD INSPECTIONS

• Complete a field log for all investigation locations in accordance with the Federal Lands Highway

Soil Description and Identification Guidelines and the Federal Lands Highway Rock

Characterization Guidelines.

The estimated solicitation for this requirement is Spring/Summer 2025.
