Performance Work Statement (PWS)

Spillway Modification Anchor Investigation Phase 2

Garrison Dam, ND

MAR 2025

1.0 General Information.

Background: The Garrison Dam – Lake Sakakawea Project was authorized by the Flood Control Act approved 22

December 1944, as part of the comprehensive plan for flood control and other purposes on the Missouri River

Basin. The authorized purposes include flood risk management, hydroelectric power, water supply, water quality control, irrigation, recreation, navigation, and fish and wildlife. The dam was constructed primarily between 1947 and 1954. Major project components include the earth-fill dam embankment, hydroelectric generating plant, and the concrete spillway.

The Garrison Dam Spillway Modification (GDSM) project, currently in design phase, involves installing additional foundation anchors in the spillway chute and stilling basin. A comprehensive anchor test program has been developed and implemented in phases. Phase 1 of the anchor test program was focused on three field anchor installations and tests to better understand foundation characteristics and early anchor production considerations.

Phase 2 of the anchor test program will include construction of concrete anchor pads and drilling, installing and testing of ASTM A722 anchor bar anchors in the Fort Union Formation to ensure the preliminary GDSM anchor design by the GDSM project is constructable, repeatable, and capable of resisting potential design loads. In addition, reducing geotechnical uncertainty with properties such as bearing capacity, undrained shear strength as well as geologic variability across site.

The primary foundation unit for anchor installation and testing is the Fort Union Group of the Tongue River

Formation. The dominant materials in the Fort Union are clay, silt, lignite, and sand, with prevalence in the order listed. The foundation has properties intermediate between soil and rock but are typically described using soil terms

(example: lean clay, CL). Geologic structure typically associated with rock (jointing, bedding planes, and discontinuities) exist within the Fort Union. The clay and silt beds are described as a “soil-like” clay-shale, stiff and highly compacted, but not cemented as rock would be described. The lignite layers are a low grade of coal, firm to hard in its un-weathered state and dark brown in color. The lignite beds are consistent across significant lateral distances and have site-specific designators (names 2U, 1U, 1L, etc. as shown in the attachments). A detailed description of the site stratigraphy will be further described in the Drilling and Invasive Activities Program Plan

(DIPP). The DIPP was prepared by the U.S. Army Corps of Engineering (USACE) and is provided as Attachment

V, GDSM DIPP, for Contractor use in preparation of the Anchor Field Installation and Testing Report.

1.1 Scope of Work: The major work activities for the GDSM Anchor Investigation Phase 2 includes pre-fieldwork submittals, mobilization of equipment to Garrison Dam, material procurement, construction of twelve (12) reinforced concrete test pads, construction of twelve (12) foundation anchors (underream, bell, and Conventional Bond Zone

(CBZ) type anchors), anchor field testing, demobilization, and all incidental activities required to fulfill the requirements of this PWS as stated herein. Activities include, but are not limited to, the following.

a. Pre-fieldwork submittals. The contractor shall prepare pre-fieldwork submittals for Government approval in advance of any planned field work.

b. Casing. Casing is required for this job. Based upon GDSM Anchor Investigation Phase 1, casing should not be sacrificial if proactive measures are taken. Should casing become unrecoverable, a modification for the material cost of the unrecoverable casing will be issued provided the

Contractor has taken reasonable measures to prevent casing from becoming seized in the ground.

c. Drilling. Various types of drill rigs are required to build the various types of anchors in this job.

Controls for measuring and inspecting foundation anchor tip profiles are required per this PWS.

d. Anchor Tendon (i.e., Bar). The anchor tendon shall be fully threaded Grade 150 steel bar meeting the requirements of ASTM A722. A variance is not permitted. Bar sizes and corrosion protection is required in accordance with this PWS.

e. Foundation Anchor Field Testing. Each foundation anchor shall be verification load tested.

Verification testing shall follow the load, duration, and cycles as shown in Attachment II, Foundation Anchor Verification and Modified Extended Creep Test Steps. These schedules are similar to FHWA NHI 05-039 and PTI DC35.1-14 testing requirements. The Contractor shall ensure that special safety considerations are defined in the APP and implemented when testing

CBZ anchors due to past failures at projects with similar weak foundations.

f. Foundation Anchor Instrumentation. The foundation anchor head and tip are to be instrumented in accordance with this PWS. The foundation anchor head shall have an automated long-term load monitoring system to measure changes in the lock-off load of each anchor. The field stress testing equipment and instruments shall be custom-built and manually operated. Each foundation anchor tip shall have two (2) strain gauges capable of measuring the force in the anchor bar at the anchor tip during testing. Two strain gauges are required for redundancy.

The Government will not exercise any supervision or control over the contract service providers performing the services herein. Such contract service providers shall be accountable solely to the Contractor who, in turn is responsible to the Government. This is a fixed priced, performance-based service contract where the

Government defines and measures desired outcomes, while Contractor methods are generally not constrained or directed.

3.0 Government Furnished Items and Services:

3.1 Utilities:

a. Water Supply. A raw (non-potable) water fire hydrant is available at the Garrison project, outside maintenance shop located at the toe of the dam. Within the anchor testing area, water may be taken from the stilling basin and outlet channel if approved in the APP.

b. Cuttings Disposal Area. Cuttings shall be captured and properly disposed of so as not to reenter the environment. The Contractor shall coordinate with Garrison project staff for a disposal location on the west side of the spillway.

c. Electrical. There is no electrical hook-up in the location of the anchor testing area. The contractor shall supply all necessary power to the work area.

d. Bathrooms. Temporary bathroom facilities shall be provided by the Contractor during the duration of the field work, and shall be made available to Government Staff for use

4.0 Contractor Furnished Items and Responsibilities: The Contractor shall furnish all supplies, equipment, facilities and services required to perform work under this contract that are not listed under Section 3.0 of this PWS.

a. Drilling Equipment. Drilling equipment and methods shall be suitable for advancing each hole to the required depth, diameter, and alignment at the correct location and with the appropriate degree of hole cleanliness. The drilling system shall be capable of drilling to a 2 degrees tolerance as measured against the specified anchor centerline.

Drilling equipment for the bell-out anchors shall be accomplished with Kelly drilling equipment (i.e., the pilot hole and bell shall be drilled and cuttings removed mechanically, without the aid of drilling fluids to remove cuttings). For other anchor types, the Contractor shall select the drilling means and methods provided they do not cause any damage to the structure or adversely affect the beneficial impact of any pre-grouting operation, or in any way inhibit bond development with the bar grout. See

Section 5.3 for restrictions and requirements for use of water and air drilling fluids for CBZ and underream anchors. During all drilling casing is required for hole stability. The casing shall be advanced with or ahead of the drilling.

b. Redrilling Equipment. Redrilling equipment and methods shall be suitable for redrilling each hole to the required diameter, depth, at the correct location and with the hole being clean of cuttings to at least the bottom of the bond zone, underream sump, or bell. Percussive drilling equipment is prohibited for redrilling. The drilling system shall be capable of following the original anchor bore hole without changing the alignment and shall not be detrimental to the pre-grout filling the voids outside the original borehole. The underream anchor drilling method shall use air as a drilling fluid; drilling fluid other than air is prohibited for underream construction. For CBZ anchors, the drilling system shall leave rough side walls in the bond zone and 5 feet above the bond zone.

c. Grouting Equipment. The grout mixer shall be a high-speed, high-shear, colloidal type grout mixer capable of continuous mechanical mixing that shall produce uniform and thoroughly mixed grout which is free of lumps and undispersed cement. The mixer shall be equipped with suitable water and admixture measuring devices calibrated to read in gallons and tenths and designed so that after each delivery the gauge can be conveniently set back to zero.

The grout pump shall be a progressive cavity type capable of pumping at rates at or below 20 gallons per minute. It shall be capable of pumping at a pressure of at least 50 psi at zero flow rate and capable of pumping at a rate fast enough to fill the hole in sufficient time to allow for a packer to be installed and the hole pressurized prior to the grout achieving initial set. The pump shall be capable of pumping both neat cement grout and sanded grout mixes. The pumping equipment shall have a digital pressure gauge capable of measuring pressures of at least 100 psi or twice the required grout pressure, whichever is greater, but shall be able to measure grouting pressure to the nearest 1 psi.

d. Watertightness Equipment. The type of single packer(s) used to isolate the stage to be watertightness tested or grouted and its means of inflation, sealing, and retrieval upon completion are the decisions and responsibilities of the Contractor. The packer shall have a minimum working pressure of 500 psi. The packer shall also be of a length sufficient to allow for proper sealing in a potentially rough sided borehole with extensive zones of permeable materials.

The watertightness pump shall be of the progressive cavity type, capable of pumping at least 50 gallons per minute, and shall be capable of being regulated for flows less than 1 gallon per minute.

e. Specialized Underream and Bell Equipment.

• Underreamed Anchors. A retractable cutter is required for underream anchors that can develop an underream diameter of 18 inches and up to 24 inches.

• Belled Anchors. A retractable tool for developing 34 inches in diameter belled drill holes is required. Bell tooling shall be top-hinged and have a spin dump at the bottom for collecting cuttings in a cleanout bucket. The cleanout bucket is required that can be attached to the bell tooling. A separate cleanout bucket is required to have onsite to clean the bell’s sump as required upon inspection. The Contractor may propose alternative heights of a cleanout bucket than shown on the drawings for COR approval.

f. Stressing/Testing Equipment. Stressing/testing equipment shall consist of a hydraulic jack with pump for applying the load, calibrated pressure gauges, and two gauges (one dial and one digital) to measure anchor movement.

The hydraulic pumps shall be pressure compensated variable displacement or have closed-loop control with a proportional relief valve and pressure transducer. Ideally, the hydraulic pump systems shall be capable of producing the anchor testing loads and autonomously holding the creep test load with an accuracy of 10 psi without manual intervention. If the Contractor is unable to meet this requirement a manual system for testing will be permitted if the operator does not manipulate the load resulting in inaccurate true creep data. The hydraulic pump system shall be capable of running automatically and manually, or if that is not possible, then manual is acceptable under the condition above. The hydraulic pump system shall be programmable with user-defined target pressure, ramp rates, and dwell times. The hydraulic pump system shall be capable of applying each load increment in less than 60 seconds. The hydraulic system shall have a digital display, showing at a minimum, test pressure (psi, reading to 1 psi and temperature compensation), ramp time (secs), and hold time (secs/minutes). The Contractor may add a dial pressure gauge to visually help hit target loads, but the digital gauge is the official load gauge.

Stressing (jacks) shall be hydraulically operated and have a capacity sufficient to stress the anchors to the specified required Test Loads within the rated capacity in one stroke. The ram travel of the stressing jack shall not be less than the theoretical elastic elongation of the total anchor length and the expected movement of the anchor pad and underream at the Maximum Test Load, but not less than 12 inches.

Stacking jacks or any multiple jack configurations for stressing an anchor are prohibited. Pumps shall be capable of applying each load increment in less than 60 seconds and shall be capable of maintaining the hydraulic pressure within 20 psi.
