Special Note for Tieback Wall & Page 1 of 31 June 3, 2008 Ground Anchor Blocks

Special Note for Tieback Wall and Ground Anchor Blocks

Carroll Co; Item No. 6-347.0

The body of this Special Note specifically addresses the Tieback Wall on this project. Requirements for Ground Anchor Blocks are included in Appendices. 1.0 DESCRIPTION

1.1 This work is for the design and construction of "Permanent Ground Anchored Tieback Walls". Use an approved Specialty Contractor that has the expertise and capability to complete the work required by this Special Note. Only Contractors pre-qualified by the Kentucky Department of Highways (the Department) as Specialty Contractors for the design and construction of "Permanent Anchored Tiedback Walls" and that meet any specific requirements for this project may perform tieback wall design and construction for this project.

1.2 Subsurface data from the geotechnical exploration is included in the Contract Plans. Rock cores (if applicable) and the Geotechnical Report(s) are available for viewing at the Geotechnical Branch in Frankfort, 502-564-2374. Contractors are encouraged to view rock cores; call a minimum of two (2) days in advance to schedule a viewing.

2.0 SCOPE OF WORK

2.1 The contract item "Tieback Retaining Wall" includes furnishing the design calculations and construction plans, materials, labor, tools, equipment, and other incidental items required for the design, construction, and testing of permanent ground anchored tieback walls as described herein. See the Contract Plans for an overview of the tieback wall(s).

2.2 A permanent ground anchor is a high strength steel tendon, fitted with a stressing anchorage at one end and a means of permitting force transfer to the grout and ground at the other end (bond zone). The permanent ground anchor tieback tendon is inserted into a prepared hole of suitable length and diameter. The ground anchor tendon is then fixed and stressed to a specified force. Refer to Figure 1 in FHWA "Ground Anchors and Anchored Systems" for the components of a ground anchor.

2.3 The term "ground anchor" is a generic term. Soil anchors and rock anchors are special cases of ground anchors. When the Contract Plans and/or other sections of this Special Note refer to rock anchor construction on this project, then assume that "ground anchor" refers to "rock anchor". In this Special Note,




consider terms such as "ground anchor", "permanent ground anchor", "ground anchor tieback", and "permanent ground anchor tieback" to be synonymous.

2.4 Subject to the requirements in the Contract Plans and this Special Note, select the permanent ground anchor type and method of installation and determine the bond length, free stressing length, and anchor diameter that will develop the design loads indicated in the Contract Plans.

2.5 In design and construction of the wall, consider the potential risks involved due to slope failure. Excavation stability, global slope stability, wall alignment, and wall stability are the Contractor's responsibilities from the beginning of work until final acceptance. Damage to property (public or private) or to the wall itself during construction is the responsibility of the Contractor. Analyze the permanent ground anchor tieback wall system in order to ensure that the wall system will function as intended.

2.6 The main body of this Special Note is general for permanent ground anchor tieback walls. Refer to the Appendix or Appendices for any project specific requirements.

Standard Specifications, the Department’s current "Kentucky Methods", the current "Manual of Field Sampling and Testing Practices", and other referenced documents.

7.2 Use only materials accepted by the Department before use. The Engineer may suspend work on the wall if the Contractor does not have acceptance of materials to be used and there is no other work on the wall that may be done. If work is suspended due to lack of material acceptance, the Contractor is fully liable for additional cost from the suspension of work. No additional contract time resulting from the suspension of work will be allowed.

8.0 CORROSION PROTECTION

Provide encapsulated (double corrosion-protected or Class I) tendons and corrosion protection for other items as described below. Refer to Figures 60, 61, and 62 in FHWA "Ground Anchors and Anchored Systems" for examples of corrosion protection for anchorages and tendons. In all cases, provide materials conforming to the Materials Section of this Special Note. Submit details of the corrosion protection to the Engineer for review and acceptance. 8.1 Anchorage Protection 8.1.1 Provide grout-filled anchorage covers for all stressing anchorages permanently

exposed to the atmosphere. Except provide a corrosion inhibiting compound for restressable anchorages. Stressing anchorages encased in concrete at least 2 inches thick do not require a cover.

8.1.2 Provide trumpets with inside diameters equal to or larger than the holes in the bearing plates. Seal the trumpets to the bearing plates such that no voids exist between the bearing plates and trumpets. Weld steel trumpets to the bearing plates. Positively seal PVC trumpets against the bearing plate and align with the tendon to prevent cracking during stressing. Overlap the trumpets over the unbonded length corrosion protection by at least 4 inches. Provide trumpets long enough to accommodate movements of the structure and the tendon during testing and stressing. On strand tendons, provide trumpets long enough to enable the tendons to transition from the diameter of the tendons along the unbonded length to the diameter of the tendons at the wedge plate without damaging the encapsulation.

8.1.3 Completely fill the trumpets with grout, except provide corrosion inhibiting compounds for restressable anchorages. Place compounds any time during construction. Provide permanent seals between the trumpet and the unbonded length corrosion protection in compound-filled trumpets. Place grout after the anchor has been tested and stressed to the lock-off load. For trumpets filled with grout, provide either a temporary seal between the trumpet and the unbonded length corrosion protection or tightly fit the trumpet over the unbonded length corrosion protection for a minimum of 4 inches. For trumpets filled with corrosion-




inhibiting grease, provide a tight fitting permanent Buna-N rubber or approved equal seal between the trumpet and the unbonded length corrosion protection. Provide a water tight seal capable of functioning for the expected life of the structure.

8.2 Unbonded Length Protection 8.2.1 Provide corrosion protection of the unbonded length by a combination of sheaths,

sheaths filled with a corrosion inhibiting compound or grout, or heat shrinkable tubes internally coated with a mastic compound, depending on the tendon class. The corrosion inhibiting compound must completely coat the tendon elements, fill the void between them and the sheath, and fill the interstices between the wires of 7-wire strands. Make provisions to retain the compound within the sheath.

8.2.2 Provide a corrosion protective sheath surrounding the unbonded length of the tendon long enough to extend into the trumpet, but not long enough to come into contact with the stressing anchorage during testing. Trim any excessive protection length.

8.2.3 For pregrouted encapsulations, provide a separate bondbreaker or common sheath for supplemental corrosion protection or to prevent the tendon from bonding to the grout surrounding the unbonded length.

8.2.4 Sheaths fabricated from a corrugated tube or a heat shrinkable tube require a separate bondbreaker. Provide a bondbreaker that prevents the tendon free stressing length from bonding to the grout surrounding the unbonded length.

8.2.5 If a grease-filled sheath is provided and the drill hole above the bond length is grouted after the anchor has been locked off, then grout the tendon inside a second sheath. If corrosion inhibiting grease is used, make provisions to prevent the grease from escaping at the ends of the sheath. Completely coat the tendon with the grease and fill the void between the tendon and the sheath. Use grease formulated to provide lubrication and inhibit corrosion. Submit details for the grease filled sheath. Unsatisfactory encapsulation or voids in the sheath will be cause for rejection of all tendons in the shipment. The Department will make no additional payment for any rejected tendons.

8.2.6 Do not drill or penetrate the encapsulation in any way to accommodate grouting of tendons. Demonstrate to the Engineer's satisfaction that the tendons are precisely centered within the encapsulation and that the tendons have double corrosion protection throughout.

8.3 Unbonded Length/Bond Length Transition

Design and fabricate the transition between the corrosion protection for the bonded and unbonded lengths to ensure continuous protection from corrosive attack. Show the transition between the bond length and the unbonded length corrosion protection in the Construction Plans.

8.4 Tendon Bond Length Protection for Encapsulated Tendons8.4.1 Provide Tendon Bond Length Protection that is:

a. capable of transferring stresses from the grout surrounding the tendon to the bond length grout;




b. able to accommodate movements during testing and after lock off; c. resistant to chemical attack from aggressive environments, grout or

grease; d. resistant to aging by ultra-violet light; e. fabricated from materials non-detrimental to the tendon; f. capable of withstanding abrasion, impact and bending during handling and

installation; and g. capable of resisting internal grouting pressures developed during grouting.

8.4.2 Provide a grout-filled, corrugated plastic encapsulation or a grout-filled, deformed steel tube. Grout the prestressing steel inside the encapsulation prior to inserting the tendon into the drill hole or after the tendon has been placed.

8.4.3 Provide centralizers or grouting techniques to ensure a minimum of 0.5 inch of grout cover over the encapsulation.

8.5 Epoxy

Fusion-bonded epoxy may be used to provide a layer of protection for the steel tendon in addition to the cement grout.

8.6 Coupler Protection8.6.1 On encapsulated bar tendons, cover the coupler and any adjacent exposed bar

sections with a corrosion-proof compound or wax-impregnated cloth tape. Cover the coupler area with a smooth plastic tube; overlap the adjacent sheathed tendon by at least 1 inch. Seal the two joints each by a coated heat shrink sleeve of at least 6 inches in length, or approved equal. Completely fill the space inside the cover tube with the corrosion-proof compound.

8.6.2 Submit corrosion protection details for strand couplers for approval of the Engineer, if specifically permitted by the contract documents.

8.7 Structural Steel and Miscellaneous Metals 8.7.1 Use one of two systems below, or a combination of the systems. Clean and

paint according to Section 607.03.23 of the Standard Specifications. a. Sacrificial Thickness - Increase the design thicknesses a minimum of 1/16"

throughout. Clean and paint all faces to be exposed in the finished structure; provide a shop-applied zinc rich primer, a field-applied moisture cure aluminum polyurethane intermediate coat, and a field-applied urethane finish coat.

b. VACANT 8.7.2 If concrete facing is not used, clean and apply a shop-applied zinc rich primer,

provide a field-applied moisture cure aluminum polyurethane intermediate coat, and a field-applied urethane finish coat to all shear studs. Shear studs do not require a sacrificial thickness or painting if concrete facing is used and the studs are completely surrounded by concrete.




9.0 CONSTRUCTION Construct the wall(s) according to the Contract Plans, Construction Plans, the Standard Specifications, and the requirements below. In all cases, provide materials conforming to the Materials Section of this Special Note. 9.1 Soldier Beams9.1.1 The Contractor is responsible for slope stability during any bench excavation

required to install soldier beams. 9.1.2 When drilled-in soldier beams are required, excavation methods and drilling tools

are at the Contractor's discretion based on site conditions; however, blasting is not permitted. If casing is not used, do not excavate for soldier beams within 24 hours of the completion of an adjacent soldier beam if the center to center spacing is less than three diameters. Dispose of excavated materials in accordance with the Standard Specifications and the contract documents.

9.1.3 Remove any obstructions at soldier beam locations. Such obstructions may include man-made materials such as old concrete foundations or natural materials such as boulders. Use special procedures and/or tools when the hole cannot be advanced using conventional augers fitted with soil teeth, drilling buckets, and/or underreaming tools. Such special procedures or tools may include but are not limited to rock augers, core barrels, air tools, hand excavation, temporary casing, and increasing the hole diameter. Promptly remove drilling tools lost in an excavation without additional compensation.

9.1.4 Use casing or slurry if necessary to maintain excavation stability and/or prevent surface sloughing. Extract temporary casing at a slow, uniform rate with the pull in line with the axis of the soldier beam. Remove temporary casings while the backfill material remains workable. When conditions warrant, pull the casing in partial stages. Do not use vibratory hammers for casing installation or removal within 50 ft. of soldier beams completed less than 24 hours. Complete casing extraction in 15 minutes or less.

9.1.5 Do not permit workpersons to enter an excavation for any reason unless both a suitable casing has been installed and adequate safety equipment and procedures have been provided to workmen entering the excavation. "Down-Hole Entry Manual: Recommended Procedures for the Entry of Drilled Shaft Foundation Excavations", prepared by ADSC, provides guideline recommendations for down-hole entry of drilled excavations.

9.1.6 Measure final soldier beam depths and check for excavation cleanliness with a suitable weighted tape or other accepted methods after final cleaning. The maximum sediment at base of each soldier beam is 0.5 inch at the time of backfill placement.

9.1.7 Install the structural steel piles so they do not vary from vertical more than 1/4 inch in 10 feet and no more than 1 inch from plan position at the top of the pile. Provide equipment for checking the dimensions and alignment of each soldier beam under the observation of the Engineer.




9.2 Timber Lagging 9.2.1 Provide a maximum gap in the lagging of 2 inches if concrete facing is used and

1 inch if concrete facing is not used. Bolts, studs, nuts, plates, etc. may be welded, to attach the lagging to the soldier pile, without any additional holes in the soldier pile.

9.3 Tendon Storage and Handling9.3.1 Handle and store tendons in such a manner as to avoid damage or corrosion.

Damage to the prestressing steel, the corrosion protection, and/or the epoxy coating as a result of abrasions, cuts, nicks, welds and weld splatter will be cause for rejection by the Engineer. Protect the prestressing steel if welding is to be performed in the vicinity. Do not ground welding leads or elective equipment to the prestressing steel. When welding electrodes are connected to any part of the structure, electrically isolate the tiebacks from the structure. Protect prestressing steel from dirt, rust, or deleterious substances. A light coating of rust on the steel is acceptable. The Engineer will reject tendons with non-repairable damage as a result of corrosion, cuts, nicks, abrasions, welds and/or weld splatter, with no additional payment for rejected tendons.

9.3.2 Exercise care in handling and storing the tendons at the site. Prior to inserting a tendon in the drill hole, the Contractor and the Engineer will examine the tendon for damage to the encapsulation and the sheathing. If, in the opinion of the Engineer, the encapsulation is damaged, repair the encapsulation in accordance with the tendon supplier's recommendations. If, in the opinion of the Engineer, the smooth sheathing has been damaged, repair it with ultra high molecular weight polyethylene tape. Spiral wind the tape around the tendon to completely seal the damaged area. Use a spiral pitch to ensure a double thickness at all points.

9.3.3 Pad banding for fabricated tendons to avoid damage to the tendon corrosion protection. Upon delivery, store and handle the fabricated anchors or the prestressing steel for fabrication of the tendons on site and all hardware in such a manner to avoid mechanical damage, corrosion, and contamination with dirt or deleterious substances.

9.3.4 Lift the pre-grouted tendons in a manner that does not cause excessive bending, which can debond the prestressing steel from the surrounding grout.

9.4 Anchor Fabrication 9.4.1 Provide anchors either shop or field fabricated and as shown in the accepted

Construction Plans and schedules. 9.4.2 Cut prestressing steel with an abrasive saw. 9.4.3 Ensure that the tendon bond length, especially for strand, is free of dirt,

manufacturers' lubricants, corrosion-inhibitive coatings, or other deleterious substances that may significantly affect the grout-to-tendon bond or the service life of the tendon.

9.4.4 Perform pregrouting of encapsulated tendons on an inclined, rigid frame or bed by injecting the grout from the low end of the tendon.




9.5 Anchor Drilling9.5.1 Anchor drilling methods are at the discretion of the Contractor. Use drilling

methods to establish a stable hole of adequate dimensions, within the tolerances specified. Drilling methods may involve: rotary, percussion, rotary/percussive or auger drilling, percussive or vibratory driven casing, core drilling, or other methods. If the hole will not stand open, install temporary casing to maintain a clean and open hole. Use a drill bit or casing crown not more than 0.1 inch smaller than the designed hole diameter.

9.5.2 If water is used in the drilling operation, dispose of the water in such a manner that erosion in the vicinity of the wall is minimized. The Contractor is cautioned against the indiscriminate use of water that could create unstable slopes above and/or below the wall. Immediately repair any damage to the site by water or erosion at no cost to the Department.

9.5.3 When Rock Anchors are required in the Contract Plans or in this Special Note, drill the hole to ensure that the bond length is developed in bedded rock. Extend the hole a minimum of 1 ft. beyond the bond length of tendon to be installed.

9.5.4 Drill holes for anchors at the locations, lengths, inclinations, and diameters shown on accepted Construction Plans and according to the following: • At the point of entry, locate the drill hole within the soldier pile or waler and

within 4 inches of the location shown on the accepted Construction Plans. • Locate the drill so the longitudinal axis of the drill hole and the longitudinal

axis of the tendon are parallel. In particular, do not drill the anchor hole in a location that requires the tendon to be bent in order to enable the bearing plate to be connected to the supported structure.

• At the point of entry, install the anchor within +/- 3o of the inclination from horizontal shown on the accepted Construction Plans.

• At the point of entry, install the anchor so that the horizontal angle made by the anchor and the structure is within +/- 3o of a line drawn perpendicular to the plane of the structure, unless otherwise shown on the accepted Construction Plans.

• Do not extend the anchors beyond the right-of-way or easement limits shown in the Contract Plans.

9.6 Tendon Insertion 9.6.1 Provide centralizers at maximum intervals of 10 feet, center to center, to insure

tendons do not contact the wall of the drill hole. Position the tendon in the drill hole so that a minimum of 0.5 inch of grout covers the encapsulation throughout the bond length; provide centralizers that permit the free flow of the grout. Provide a minimum of 2 centralizers in the bond length, an upper centralizer located within 5 feet of the top of the bond length and a lower centralizer located within 2 feet of the bottom of the bond length. Provide a minimum of 2 centralizers in the unbonded length, an upper centralizer located within 5 feet of the lower end of the steel trumpet and a lower centralizer located within 2 feet of the bottom of the unbonded length. If multi-element tendons are used without a fixed anchorage at the lower end, make provisions for adequate spacing of the




tendon elements to achieve proper grout coverage. Centralizers are not required on pressure injected anchors installed in coarse grained soils when the grouting pressure exceeds 150 psi, nor on hollow stem-augered anchors when they are grouted through the auger with grout having a slump of 9 inches or less.

9.6.2 Thoroughly clean holes of all dust, grease or other deleterious material prior to inserting the tendon. Insert the tendon into the drill hole to the prescribed length without difficulty. When the tendon cannot be completely inserted, remove the tendon from the drill hole and clean or redrill the hole to permit insertion. Do not drive or force partially inserted tendons into the hole.

9.6.3 Take care to insure that the tendon's corrosion protection is not damaged during handling or installation. Degrease the bond length of strands or wires prior to installation by using a degreaser or a method accepted by the Engineer. Do not leave residue from the degreasing on the tendon. Substances other than a degreaser may be used subject to acceptance by the Engineer. All costs of cleaning tendons are incidental to the Contract price for the wall.

9.6.4 Field personnel will inspect each anchor tendon during installation into the drill hole or casing. Repair damage to the corrosion protection system, or replace the tendon if not repairable. Reconnect loose spacers or centralizers to prevent shifting during insertion. Repair damaged fusion-bonded epoxy coatings in accordance with the manufacturer's recommendations. If the patch is not allowed to cure prior to inserting the tendon in the drill hole, protect the patched area by tape or other suitable means.

9.6.5 Control the rate of placement of the tendon into the hole such that the sheathing, coating, and grout tubes are not damaged during installation of the tendon. Do not subject anchor tendons to sharp bends. The bottom end of the tendon may be fitted with a cap or bullnose to aid its insertion into the hole, casing, or sheathing.

9.7 Grouting 9.7.1 Use grouting equipment that produces a grout free of lumps and undispersed

cement. Use a positive displacement grout pump equipped with a pressure gauge to monitor grout pressures. Use a pressure gauge capable of measuring pressures of at least 150 psi or twice the actual grout pressures used, whichever is greater. Use grouting equipment sized to enable the grout to be pumped in one continuous operation. Use a mixer capable of continuously agitating the grout. Auger mixing of the grout is not allowed. Ensure that mixing and storage times do not cause excessive temperature buildup in the grout.

9.7.2 Inject the grout from the lowest point of the drill hole. Pump the grout through grout tubes, casing, hollow-stem-augers, or drill rods. Record the quantity of the grout and the grout pressures for each anchor Control the grout pressures and grout takes to prevent excessive heave or fracturing. Do not drill or puncture the sheath and/or tubing in any way to accommodate grouting of tendons.

9.7.3 Prevent the grout at the top of the drill hole from contacting the back of the structure or the bottom of the trumpet.

9.7.4 If the ground anchor is installed in a fine-grained soil using drill holes larger than 6 inches in diameter, then place the grout above the top of the bond length after




the anchor has been tested and stressed. The Engineer will allow the Contractor to grout the entire drill hole at the same time if the Contractor can demonstrate that its particular ground anchor system does not derive a significant portion of its load-carrying capacity from the soil above the bond length portion of the anchor.

9.7.5 The grout tube may remain in the hole on completion of grouting if the tube is filled with grout.

9.7.6 After grouting, allow the ground anchor tieback to remain undisturbed until the grout has cured sufficiently to allow the anchor to be tested.

9.8 Anchorage Installation9.8.1 Install the anchor bearing plate and the anchor head or nut perpendicular to the

tendon, within +/- 3o and centered on the bearing plate, without bending or kinking the prestressing steel elements. Ensure that wedge holes and wedges are free of rust, grout, and dirt.

9.8.2 Clean the stressing tail and protect it from damage until final testing and lock-off. After the Engineer has accepted the anchor, cut the stress tail to its final length according to the tendon manufacturer's recommendations.

9.8.3 Extend the corrosion protection surrounding the unbonded length of the tendon up beyond the bottom seal of the trumpet or 4 inches into the trumpet if no trumpet seal is provided. If the protection does not extend beyond the seal or sufficiently far enough into the trumpet, extend the corrosion protection or lengthen the trumpet.

9.8.4 Do not allow the corrosion protection surrounding the unbonded length of the tendon to contact the bearing plate or the anchor head during testing and stressing. If the protection is too long, trim the corrosion protection to prevent contact.

9.8.5 Cover the insulation over the anchorage and bearing plates not encased in concrete with insulation fabricated from a heat-shrinkable cap with an elastic adhesive, a moldable sealant, or other suitable material. Submit manufacturer's literature describing the insulation to the Engineer for review.

9.8.6 Provide anchorage insulation meeting the following requirements: a. an electrical insulator; b. resistant to attack from cement, grease, or aggressive environments; c. non detrimental to the prestressing steel; and d. capable of withstanding atmospheric exposure and ultraviolet light.

9.9 Cutting Tendon ProtrusionsDo not cut the portion of the tendon protruding over the anchorage until all testing, retesting, restressing, and final lock-off is completed on that wall section. For purposes of cutting tendons, a wall section is that portion of a completed wall that encompasses five vertical piles, all anchors, and all lagging from the bottom of lagging to the top of lagging. Cut tendons according to manufacturer's recommendations and as approved by the Engineer. Take care not to damage the tendon. Torches are not permitted for cutting strand tendons. Protect the cut ends of tendons from corrosion until encapsulation.




9.10 Excavation Limit excavation in front of walls to 2 ft. below any ground anchor until that anchor has been completed, tested, and locked off.

9.11 Drainage and Backfill Install drainage in accordance with Section 603.03.05

of the Standard Specifications. Backfill and compact any areas behind the lagging requiring backfilling prior to applying any loads to the anchors.

9.12 Wall Alignment and Facing Ensure that the wall is compatible with the

horizontal and vertical alignment indicated in the Contract Plans. Survey control is the front face of the wall. Construct the exposed face of the wall to be straight and smooth with no discontinuities. Protrusions beyond the face of the walls are not allowed. Completely fill any voids between concrete facing and lagging with grout. Provide architectural treatment for concrete facing as shown in the Contract Plans. Apply Masonry Coating to Concrete Facing in accordance with the Contract Plans and Section 601 of the Standard Specifications.

10.0 PERMANENT GROUND ANCHOR TESTING AND ACCEPTANCE 10.1 General

Test each ground anchor within 21 calendar days of installation and provide a written summary of the test results to the Engineer within 7 calendar days after each test; include the following: • bonded length • unbonded length • jacking length • number of strands or bar size • area of strands or bar • heat number • coil number, and • modulus of elasticity.

Failure to meet the submittal deadlines for anchor test results may result in the Engineer suspending anchor installation. Apply no more than ten (10) percent of the design load prior to testing. Apply a test load no less than 1.33 times the design load and no more than 80 percent of the specified minimum ultimate tensile strength of the prestressing steel in the tendon. Apply the test load simultaneously to the entire tendon and do not stress single elements of multi-element tendons.

Before testing, perform backpacking sufficient to insure that the soil is flush with the back face of the wall throughout the area affected, but no less than 2 pile spaces each side of the ground anchor tested. Excessive deflection during




testing requires additional backpacking. All work and materials required for backpacking are at no additional cost to the Department. The Department will not make separate payment for the testing required in this section. All testing required in this section are included in the price of the wall(s).

10.2 Testing Equipment 10.2.1 Use the following testing equipment:

1. Use a dial gauge or vernier scale capable of measuring to 0.001 inch to measure the ground anchor tieback movement. Use a gage or scale with a minimum travel equal to at least 125 percent of the theoretical elastic elongation of the unbonded length plus the tendon bond length at the maximum test load. Measure the total and creep movements of the anchor to the nearest 0.001 inch with the dial gauge. Support the gauge on a fixed base independent of the structure.

2. Use a hydraulic jack, primary pressure gauge, and pump to apply the test load. Use a jack and pressure gauge that has been calibrated as a unit against a certified gauge by an independent firm within 3 months of use; if necessary, re-calibrate during the project to keep the calibration current. Submit the calibration curves for the primary pressure gauge to the Engineer for acceptance prior to performing any tests. Use a pressure gauge graduated in 100 psi increments or less to measure the applied load for Proof and Performance Tests and use equipment capable of measuring and maintaining the hydraulic pressure within 50 psi for Extended Creep Tests. Use a jack with a ram travel at least 125 percent of the theoretical elastic elongation of the tendon at the maximum test load.

3. Keep a second calibrated pressure gauge at the site as a backup gauge. Use a gauge calibrated within 3 months of use with the test jack and primary pressure gauge or by an independent firm using the same certified gauge as described above; if necessary, re-calibrate during the project to keep the calibration current. Submit the calibration curves for the backup pressure gauge to the Engineer for acceptance prior to performing any tests. Use the primary pressure gauge to measure hydraulic jack pressure for the determination of load. Use the backup pressure gauge to check the performance of the primary pressure gauge on each Performance Test. Store the backup pressure gauge inside and do not subject it to rough treatment. If the load determined by the backup pressure gauge and the load determined by the primary pressure gauge are within ten (10) percent of each other, assume that the primary pressure gauge is functioning properly. If the load determined by the backup pressure gauge and the load determined by the primary pressure gauge differ by more than ten (10) percent, recalibrate the jack, the primary pressure gauge and backup pressure gauge at no expense to the Department.




4. Use an electrical load cell and readout or a vibrating wire load cell and readout to monitor changes in load during constant load-hold periods for performance and extended creep tests. Use a load cell calibrated within 1 year of use; if necessary, re-calibrate during the project to keep the calibration current.

5. Place the stressing equipment over the anchor tendon in such a manner that the jack, bearing plates, load cells and stressing anchorage are axially aligned with the tendon and the tendon is centered within the equipment.

10.2.2 Determine the stressing equipment, the sequence of stressing, and the procedure to be used for each stressing operation at the beginning of the project. Use the equipment strictly in accordance with the manufacturer's operating instructions.

10.2.3 Use stressing equipment capable of stressing the entire tendon in one stroke to the specified Test Load and equipment capable of stressing the tendon to the maximum specified Test Load within 75 percent of the rated capacity. Use a pump capable of applying each load increment in less than 60 seconds.

10.2.4 Use equipment that permits the tendon to be stressed in increments so that the load in the tendon can be raised or lowered in accordance with the test specifications, and allow the anchor to be lift-off tested to confirm the lock-off load.

10.2.5 Use stressing equipment calibrated within the specified time increments within an accuracy of plus or minus two (2) percent prior to use and traceable to the National Institute of Standards and Technology (NIST). Keep the calibration certificate(s) and graph(s) available on site at all times.

10.3 Load Testing Setup10.3.1 Set up the dial gauges to bear on the pulling head of the jack so their stems are

coaxial with tendon direction. Support the gauges on an independent, fixed frame, such as a tripod, which will not move as a result of stressing or other construction activities during the operation.

10.3.1 Prior to setting the dial gauges, place the Alignment Load (AL) accurately on the tendon. The magnitude of AL depends on the type and length of the tendon.

10.3.2 Avoid regripping of strands, which would cause overlapping wedge bites, or wedge bites on the tendon below the anchor head.

10.3.3 Stressing and testing of multiple element tendons with single element jacks is not permitted.

10.3.4 Begin stressing only after the grout has reached adequate strength. 10.4 Proof Tests10.4.1 Perform Proof Tests on all ground anchors not subjected to Performance or

Extended Creep Tests. Perform the Proof Tests by incrementally loading in accordance with the Proof Test Schedule. Increase the load from one increment to another immediately after recording the anchor movement. Measure and record the anchor movement to the nearest 0.001 inch with respect to an independent fixed reference point at the alignment load and at each increment of load. Monitor the load with the primary pressure gauge. Hold the load just long enough to record the movement, except hold the maximum load for 10 minutes.




10.4.2 Adjust the jack as necessary in order to maintain a constant load. Start the load-hold period as soon as the maximum test load is applied. Measure and record the anchor movement with respect to a fixed reference at 1 minute, 2, 3, 4, 5, 6 and 10 minutes. If the anchor movement between one (1) minute and ten (10) minutes exceeds 0.04 inches, hold the maximum test load for an additional 50 minutes. If the load hold is extended, record the anchor movements at 15 minutes, 20, 30, 40, 50 and 60 minutes.

10.7 Ground Anchor Lock -Off After testing has been completed for a particular

anchor, lock off that anchor such that, after seating losses (i.e. wedge seating), a load of 75 +/- 10 percent of the design load for that anchor has been applied to the tendon.

10.8 Lift-Off Tests After transferring the load to the anchorage, and prior to

removing the jack, perform a Lift-Off Test on each ground anchor tieback to confirm the magnitude of the load in the anchor tendon. Determine this load by reapplying load to the tendon to lift off the wedge plate (or anchor nut) without unseating the wedges (or turning the anchor nut). This moment represents zero time for any long time monitoring.

10.9 Ground Anchor Acceptance Criteria 10.9.1 A performance-tested or proof-tested ground anchor with a 10 minute load hold

is acceptable if the: (1) anchor resists the maximum test load with less than 0.04




inches of movement between 1 minute and 10 minutes; and (2) total elastic movement at the maximum test load exceeds 80 percent of the theoretical elastic elongation of the unbonded length.

10.9.2 A performance-tested or proof-tested ground anchor with a 60 minute load hold is acceptable if the: (1) anchor resists the maximum test load with a creep rate that does not exceed 0.08 inches in the last log cycle of time; and (2) total elastic movement at the maximum test load exceeds 80 percent of the theoretical elastic elongation of the unbonded length.

10.9.3 A ground anchor subjected to extended creep testing is acceptable if the: (1) anchor resists the maximum test load with a creep rate that does not exceed 0.08 inches in the last log cycle of time; and (2) total elastic movement at the maximum test load exceeds 80 percent of the theoretical elastic elongation of the unbonded length.

10.9.4 If the initial lift-off reading is not within plus or minus five (5) percent of the lock-off load, then adjust the tendon load accordingly and repeat the initial lift-off reading.

10.10 Procedures for Ground Anchors Failing Acceptance Criteria 10.10.1Replace ground anchors that do not satisfy the minimum apparent free length

criteria at no additional cost to the Department or lock off at not more than 50 percent of the maximum acceptable load attained. In this event, no further acceptance criteria are applied.

10.10.2Regroutable ground anchors which satisfy the minimum apparent free length criteria but which fail the extended creep test at the test load may be postgrouted and subjected to an enhanced creep criterion. This enhanced criterion requires a creep movement of not more than 0.04 inches between 1 and 60 minutes at test load. Lock off anchors that satisfy the enhanced creep criterion at the design lock-off load. Anchors that cannot be postgrouted or regroutable anchors that do not satisfy the enhanced creep criterion will be either rejected or locked off at 50% of the maximum acceptable test load attained. In this event, no further acceptance criteria are applied. The maximum acceptable test load with respect to creep is the load where acceptable creep movements are measured over the final log cycle of time.

10.10.3In the event that a ground anchor fails, modify the design and/or construction procedures. These modifications may include, but are not limited to: installing additional anchors, modifying the installation methods, reducing the anchor design load by increasing the number of anchors, increasing the anchor length, or changing the anchor type. Any modification of design or construction procedures are at no charge to the Department and with no extension of contract time. Incorporate any redesigns or modifications to the wall, tiebacks, tieback geometry, etc. only with prior acceptance by the Engineer.

SN for TB Wall & Ground Anchors Blocks - Appendix C Page 1 of 5 June 3, 2008



http://www.eng.uwyo.edu/civil/publications/reports/

C7.0 STRUCTURAL DESIGN Perform structural design of the blocks, connections, etc. in accordance with all other requirements in the Contract Documents and according to the requirements in this Special Note and applicable referenced documents. Primary design references include but are not limited to: FHWA Publication FHWA-IF-99-015, "Ground Anchors and Ground Anchored Systems", June 1999; AASHTO Standard Specifications for Highway Bridges, Current Edition, with all interims; AISC Steel Construction Manual. C8.0 MAXIMUM ANCHOR LENGTHS Ensure that all anchors are located within right-of-way. C9.0 ALLOWABLE BEARING CAPACITY The allowable bearing capacity for ground anchor reaction blocks is 3.33 ksf. C10.0 GROUTED SUPPORT ELEMENTS In order to improve the bearing capacity of the ground anchor reaction blocks, "grouted support elements" (GSE's) will be required adjacent to each ground anchor. The GSE's will consist of four six-inch diameter holes drilled adjacent to each ground anchor and backfilled with grout meeting the requirements of Section 6 of the Special Note Ground Anchors. Refer to the GSE schematic in Appendix E. The GSE's are not directly accounted for in the design of the reaction blocks. C11.0 NON-PRODUCTION TRIAL ANCHOR Non-production trial anchors for the anchor blocks are not required. However, in order to evaluate the bond performance, the extended creep test for the tieback wall must be performed and accepted prior to beginning installation of anchors for the anchor blocks. C12.0 PERFORMANCE TESTING AND ANCHOR ACCEPTANCE Performance testing is required for all anchor blocks. The loading procedures described below are designed to preload the anchor system to mitigate against long-term creep. The Department will consider alternate loading procedures if proposed by the Contractor. C12.1 Performance TestsC12.1.1 Conduct the Performance Tests by incrementally loading and unloading ground

anchor tiebacks in accordance with the Performance Test Schedule. Raise the load from one increment to another immediately after recording the anchor movement. Measure and record the anchor movement to the nearest 0.001 inch with respect to an independent fixed reference point at the alignment load and at each increment of load. Monitor the load with the primary pressure gauge. Place the reference pressure gauge in series with the primary pressure gauge during each performance test. If the loads determined by the primary and reference pressure gauges differ by more than ten (10) percent, recalibrate the jack, primary pressure gauge, and reference pressure gauge at no expense to the Department. Hold the load just long enough to record the movement, except hold the maximum load for 10 minutes.




C12.1.2 Use a load cell to monitor small changes in load during constant load-hold periods.

C12.1.3 Adjust the jack as necessary in order to maintain a constant load. Start the load-hold period as soon as the maximum test load is applied and measure the anchor movement, with respect to a fixed reference. Measure and record at 1 minute, 2, 3, 4, 5, 6 and 10 minutes. If the movement between one (1) minute and ten (10) minutes exceeds 0.04 inches, hold the maximum test load for an additional 50 minutes. If the load hold is extended, record the movement at 15 minutes, 20, 25, 30, 45 and 60 minutes.

C12.1.4 Plot Performance Test Data as shown in Figures 69 and 70 of FHWA "Ground Anchors and Anchored Systems".

C12.2 Ground Anchor Lock -Off After testing has been completed for a particular anchor, lock off that anchor such that, after seating losses (i.e. wedge seating), a load of 75 +/- 10 percent of the design load for that anchor has been applied to the tendon, unless an alternate lock-off load is approved.

C12.3 Lift-Off Tests After transferring the load to the anchorage, and prior to

removing the jack, perform a Lift-Off Test on each ground anchor tieback to confirm the magnitude of the load in the anchor tendon. Determine this load by reapplying load to the tendon to lift off the wedge plate (or anchor nut) without unseating the wedges (or turning the anchor nut). This moment represents zero time for any long time monitoring.

C12.4 Ground Anchor Acceptance CriteriaC12.4.1 A performance-tested ground anchor with a 10 minute load hold is acceptable if

the: (1) anchor resists the maximum test load with less than 0.04 inches of movement between 1 minute and 10 minutes; and (2) total elastic movement at the maximum test load exceeds 80 percent of the theoretical elastic elongation of the unbonded length.

C12.4.2 A performance-tested ground anchor with a 60 minute load hold is acceptable if the: (1) anchor resists the maximum test load with a creep rate that does not exceed 0.08 inches in the last log cycle of time; and (2) total elastic movement at the maximum test load exceeds 80 percent of the theoretical elastic elongation of the unbonded length.

C12.4.3 If the initial lift-off reading is not within plus or minus five (5) percent of the lock-off load, then adjust the tendon load accordingly and repeat the initial lift-off reading.

C12.5 Procedures for Ground Anchors Failing Acceptance CriteriaC12.5.1 Replace ground anchors that do not satisfy the minimum apparent free length

criteria at no additional cost to the Department or lock off at not more than 50 percent of the maximum acceptable load attained. In this event, no further acceptance criteria are applied.

C12.5.2 Regroutable ground anchors which satisfy the minimum apparent free length criteria but which fail the extended creep test at the test load may be postgrouted and subjected to an enhanced creep criterion. This enhanced criterion requires a creep movement of not more than 0.04 inches between 1 and 60 minutes at test load. Lock off anchors that satisfy the enhanced creep criterion at the design lock-off load. Anchors that cannot be postgrouted or regroutable anchors that do not satisfy the enhanced creep criterion will be either rejected or locked off at 50% of the maximum acceptable test load attained. In this event, no further acceptance criteria are applied. The maximum acceptable test load with respect to creep is the load where acceptable creep movements are measured over the final log cycle of time.

C12.5.3 In the event that a ground anchor fails, modify the design and/or construction procedures. These modifications may include, but are not limited to: installing additional anchors, modifying the installation methods, reducing the anchor




design load by increasing the number of anchors, increasing the anchor length, or changing the anchor type. Any modification of design or construction procedures are at no charge to the Department and with no extension of contract time. Incorporate any redesigns or modifications to the wall, tiebacks, tieback geometry, etc. only with prior acceptance by the Engineer.

C13.0 MEASUREMENT AND PAYMENT The Department will measure and pay for the accepted quantities of "Lower Slope Stabilization" per Linear Foot. The number of linear feet will include the total length of the slope stabilized by the anchor blocks. The measured quantity for payment will be the distance from the center of the first accepted ground anchor to the center of the last accepted ground anchor as measured in the longitudinal direction of the roadway.

See Exhibit 1.

3.6 The scope of the project, including a list of definable work activities. A definable work activity is separate and distinct from other tasks, requires specific crews or Subcontractors, has different specifications, and has separate control requirements. It could be identified by different crews or Subcontractors, or it could be work performed by the same trade in a different environment. Each activity must have construction tolerances and workmanship standards identified for use by construction crews and sampling/testing frequencies identified for the QCP personnel. This list will be agreed upon during the coordination meeting.





4.0 CONTROL QCP is the means by which the Contractor ensures the quality and construction, to include subcontractors and suppliers, and complies with the requirements of the Contract. At least 3 phases of control must be conducted by the QCP Manager for each definable work activity as follows: 4.1 Preparatory Phase Perform this phase prior to beginning work in an

activity and include: 4.1.1 Review all the Contractor’s Construction and Materials Submittals

(including those required by the Special Note for Tiedback Walls, steel mill test reports, tendon QC reports, shop drawings, etc.) and provide written comments signed by the QCP Manager and Lead Inspector, to the Department within 14 calendar days; include specific recommendations for acceptance, acceptance with revisions, or non-acceptance of each submittal.

4.1.2 Prior to the start each work activity, the Contractor and QCP Manager are encouraged to conduct a meeting with each crew to discuss in detail with each crew member the quality standards and workmanship identified in the Preparatory Phase. The importance and role of each crew member in achieving quality should be stressed.

The Department will return the QCP to the Contractor within fourteen (14) calendar days (estimated) after submittal with requests for changes, if applicable. The Contractor will then have seven (7) calendar days to correct and make changes and resubmit the QCP to the Engineer. Work cannot begin on an activity until after the QCP for that activity has been approved by the Engineer.

5.2 Subsequent Approvals Once the Contractor begins work under the approved QCP, continuously prosecute the work in accordance with the QCP. Changes must be approved by the Engineer prior to implementation.





6.0 DOCUMENTATION The Contractor and QCP personnel are advised that any deliberate action to the detriment of the QCP will be grounds for defaulting the Contract. This includes but is not limited to any deliberate omissions, deliberate cover-ups, or attempts by the Contractor to withhold information from the Department. Allow direct communication between QCP personnel and the Department. The Contractor and any Subcontractor involved in such detrimental action will not be considered for future bids until requalified. Maintain current records providing factual evidence that required quality control activities and tests have been performed. Include the work of subcontractors and suppliers. Document extended creep, performance, and proof tests in accordance with the Special Note for Tiedback Walls. Generate and update an anchor test summary similar to what is shown in Exhibit 2. Forms for these records must be approved by the Department. Submit all records with the last pay estimate, including but not limited to sketch books, and as-built plans. The Department will make the final payment only after all documentation has been submitted. 7.0 PAYMENT The Department will pay for Quality Control at the contract Lump Sum amount. The Department considers payment as full compensation for all labor and costs associated with performing Quality Control. In addition to conforming to Subsection 113.09 of the Standard Specifications for Road and Bridge Construction, there are the following requirements. The Department will include payment for 20 percent Lump Sum for the QCP in the first estimate. The Department will pay the remaining 80 percent based on the percentage of work completed. Additional payment for the QCP will be made when time or extra work is added according to Subsection 104.03 for the bid items included in the QCP. Additional work added to other parts of the contract will not permit additional payment for the QCP. Code Pay Item Pay Unit 2572 Quality Control Lump Sum

Special Note for Alternate Slope Stabilization Methods

CARROLL COUNTY CID 081019 - KY 389 SLOPE STABILIZATION

1.0 Alternate Design Requirements Bidders will be permitted to propose alternate slope stabilization methods that may be used in lieu of either or both the tieback retaining wall and/or ground anchor blocks as provided in the "Special Note for Tieback Wall and Ground Anchor Blocks". Bidders electing to propose alternate designs will forfeit their right to file a claim resulting from their alternate design. The Department reserves the right to not award a contract for any bid containing proposed alternate methods. Alternate designs must be performed by or under the direct supervision of a Professional Engineer licensed in the Commonwealth of Kentucky. The alternate method(s) must generally be equivalent to or better than the tieback retaining wall and/or ground anchor blocks with regard to items shown on the Typical Section in Appendix E of the "Special Note for Tieback Wall and Ground Anchor Blocks". This includes but is not necessarily limited to: global factor of safety, design loads, soil strength parameters, sliding mass failure surface, and groundwater conditions. Alternate stabilization methods must have a minimum service life of 75 years. The alternates may directly or indirectly affect one or more of the bid items below. Work associated with these items may be modified but neither the work nor the bid items will be eliminated.

• Upper Slope Stabilization • Lower Slope Stabilization • Instrumentation • Horizontal Drains • Foundation Preparation • Quality Control

All bidders must indicate if their bid is based on the stabilization methods shown in the "Special Note for Tieback Wall and Ground Anchor Blocks" or if they are proposing alternate methods. Bidders electing to propose alternates must submit, with their bid, documentation that includes conceptual drawings of their proposed method and indicates which bid items will be affected by the alternate. This documentation should include enough detail for the Department to evaluate the alternate relative to general design criteria. 2.0 Evaluation of Alternates and Award of Contract If an alternate appears to be acceptable based on information included with the bid, the Department will invite the apparent low bidder to submit a detailed proposal containing design calculations, plans, and proposed construction specifications. The detailed proposal must contain sufficient information for the Department to immediately determine if the alternate is acceptable. Failure to respond within 21 calendar days after the invitation is issued will result in forfeiture of the bid. The Department may award the contract if a proposed alternate is acceptable. If an alternate is not acceptable, the Department may ask the bidder to modify their design and/or provide the tieback wall and ground anchors as specified in the "Special Note for Tieback Walls and Ground Anchor Blocks" at the original bid prices. If an agreement cannot be reached, the bidder will have the option of withdrawing their bid. If the contract is not awarded to the apparent low bidder, then the Department may follow the same procedures with the second-lowest and subsequent bidders. A bidder that elects to withdraw their bid due to not meeting requirements for alternates will not forfeit their bid bond. The Department will not release any bid bonds until either the contract has been awarded or the Department decides to re-let or cancel the project.

EXECUTIVE BRANCH CODE OF ETHICS

In the 1992 regular legislative session, the General Assembly passed and Governor Brereton Jones signedSenate Bill 63 (codified as KRS 11A), the Executive Branch Code of Ethics, which states, in part:

KRS 11A.040 (6) provides:

No present or former public servant shall, within six (6) months of following termination of his office oremployment, accept employment, compensation or other economic benefit from any person or businessthat contracts or does business with the state in matters in which he was directly involved during histenure. This provision shall not prohibit an individual from returning to the same business, firm,occupation, or profession in which he was involved prior to taking office or beginning his term ofemployment, provided that, for a period of six (6) months, he personally refrains from working on anymatter in which he was directly involved in state government. This subsection shall not prohibit theperformance of ministerial functions, including, but not limited to, filing tax returns, filing applicationsfor permits or licenses, or filing incorporation papers.

KRS 11A.040 (8) states:

A former public servant shall not represent a person in a matter before a state agency in which theformer public servant was directly involved, for a period of one (1) year after the latter of:

a) The date of leaving office or termination of employment; orb) The date the term of office expires to which the public servant was elected.

This law is intended to promote public confidence in the integrity of state government and to declare as publicpolicy the idea that state employees should view their work as a public trust and not as a way to obtain privatebenefits.

If you have worked for the executive branch of state government within the past six months, you may be subjectto the law's prohibitions. The law's applicability may be different if you hold elected office or arecontemplating representation of another before a state agency.

Also, if you are affiliated with a firm which does business with the state and which employs former stateexecutive-branch employees, you should be aware that the law may apply to them.

In case of doubt, the law permits you to request an advisory opinion from the Executive Branch EthicsCommission, Room 136, Capitol Building, 700 Capitol Avenue, Frankfort, Kentucky 40601; telephone (502)564-7954.
