Such checking by the Engineer shall not relieve the Contractor of his responsibility to perform all Work in connection with Contract Drawings and Specifications and to the lines and grades given therein." ITEM 107.3-OWNER'S OFFICERS,EMPLOYEES OR AGENTS SC-107.3.2 Replace Item 107.3.2 with the following new paragraph: "107.3.2 Conflict of Interest City Charter states that no officer of the City shall have a financial interest, direct or indirect, in any contract with the City, nor shall be financially interested, directly or indirectly, in the sale to the City of any land, or rights or interest in any land,materials, supplies or services. This prohibition does not apply when the interest is represented by ownership of stock in a corporation involved, provided such stock ownership amounts to less than one percent (1%) of the corporation stock. Any violation of this prohibition will constitute malfeasance in office. Any officer or employee of the City found guilty thereof should thereby forfeit his office or position. Any violation of this prohibition with the knowledge, expressed or implied, of the persons or corporations contracting with the City shall render the contract voidable by the City Manager or the City Council. The Contractor represents that no employee or officer of the City has an interest in the Contractor." 3-5 Standard Specifications Supplementary Conditions ITEM 107.14-STATE AND LOCAL SALES AND USE TAXES SC-107.14 Delete Item 107.14 and substitute the following in lieu thereof: "107.14 Recent legislation has removed the sales tax exemption previously provided by Section 151.311 of the Tax Code covering tangible personal property purchased by a contractor for use in the performance of a contract for the improvement of City-owned realty. It is still possible, however, for a contractor to make tax-free purchase of tangible personal property, which will be incorporated into and become part of a City construction project through the use of a "separated contract" with the City. A "separated contract" is one, which separates charges for materials from charges for labor. Under such a contract, the contractor becomes a "seller" of those materials, which are incorporated into the project, such as bricks, lumber, concrete, paint, etc. The contractor issues a resale certificate in lieu of paying the sales tax at the time such items are purchased. The contractor then receives an exemption certificate from the city for those materials. (This procedure may not be used, however, for materials, which do not become a part of the finished product. For example, equipment rentals, form materials, etc. are not considered as becoming"incorporated"into the project). Utilization of this "separated contract" approach eliminates the need for bidders to figure in sales tax for materials, which are to be incorporated into the project. The successful bidder's bid form will be used to develop the "separated contract" and will determine the extent of the tax exemption. Upon execution of the construction contract, the contractor shall furnish a breakdown (per item) of 1) materials incorporated into the project; and 2) labor, equipment, supervision and materials not incorporated into the project." ITEM 107.19-PROTECTION OF WORK AND OF PERSONS AND PROPERTY SC-107.19.2.1 Add the following new Item 107.19.2.1 immediately after Item 107.19.2: "107.19.2.1 Should CONTRACTOR cause damage to the work or property of any separate Contractor at the site, or should any claim arising out of CONTRACTOR'S, OWNER, ENGINEER, Consulting Engineer or any other person, CONTRACTOR shall promptly attempt to settle with such other Contractor by agreement, or to otherwise resolve the dispute by arbitration or at law. CONTRACTOR shall, to the fullest extent permitted by Laws and Regulations, indemnify and hold OWNER, ENGINEER and Consulting Engineer harmless from and against all claims, damages, losses and expenses (including, but not limited to, fees of engineers, architects, attorneys and other professionals and court and arbitration costs) arising directly, indirectly or consequentially out of any action, legal or equitable, brought by any separate Contractor against OWNER, ENGINEER or Consulting Engineer to the extent based 3-6 Standard Specifications Supplementary Conditions on a claim arising out of CONTRACTOR'S performance of the Work. Should a separate Contractor cause damage to the work or property of CONTRACTOR or should the performance of work by any separate Contractor at the site give rise to any other claim, CONTRACTOR shall not institute any action, legal or equitable, against OWNER, ENGINEER or Consulting Engineer or permit any action against any of them to be maintained and continued in its name or for its benefit in any court or before any arbiter which seeks to impose liability on or to recover damages from OWNER, ENGINEER or Consulting Engineer on account of any such damage or claim. If CONTRACTOR is delayed at any time in performing or furnishing Work by any act or neglect of a separate Contractor and OWNER and CONTRACTOR are unable to agree as to the extent of any adjustment in Contract Time attributable thereto, CONTRACTOR may make a claim for an extension of time in accordance with Item 1.36. An extension of the Contract Time shall be CONTRACTOR's exclusive remedy with respect to OWNER, ENGINEER and Consulting Engineer for any delay, disruption,interference or hindrance caused by any separate Contractor." ITEM 107.23—EXISTING STRUCTURES,FACILITIES AND.APPURTENANCES SC-107.23.2a Add the following new Item 107.23.2a immediately after Item 107.23.2: "107.23.2a Existing Utilities and Sewer Lines: The Contractor shall be responsible for the protection of all existing utilities or service lines crossed or exposed by the construction operations. Where existing utilities or service lines are cut, broken or damaged, the CONTRACTOR shall replace the utilities or service lines with the same type of original construction, or better, at his own cost and expense.

The right is reserved to the owner of any public utility to enter upon the limits of the project for the purpose of making such changes or repairs of their property that may be made necessary by the performance of this contract." ITEM 108.1—PROGRESS SCHEDULE SC-108.1 Amend the first sentence of Item 108.1 by adding the following at the beginning of the sentence: "If requested by Owner,Engineer or Contractor". ITEM 108.3-OTHER CONTRACTORS; OBLIGATION TO COOPERATE 3-7 Standard Specifications Supplementary Conditions SC-108.3 Delete the last sentence of the second paragraph and substitute the following in lieu thereof: "In such event, Contractor shall be entitled to an extension of working time only for unavoidable delays verified by the Engineers, as provided in Item 108.8; however, no increase in the contract price shall be due the Contractor." Insert the following sentence at the end of the second paragraph of Item 108.3: "The ENGINEER shall coordinate such other work with the CONTRACTOR and schedule events to minimize delay caused to the CONTRACTOR.

Re-tying shall be in a manner to produce a closed cell and re-tying of the gabion shall be in the same manner as the assembly. Excess mesh wire shall be cut off or be tightly and neatly laced down in accordance with the following methods: 3.8.2 Bevels: Two of the methods are: A. Cut or untie the bottom of the end panel and re-tie at the desired angle. Cut or fold and re-tie the excess mesh. Note: This is not the generally preferred method. Short gabion lengths may be required to produce the angle at the correct location. This method is generally recommended for angles not exceeding 20 degrees. B. Cut the gabion on three sides at the point where the angle is to be made. Sharply bend the uncut side, overlap the cut pieces and re-tie. Note: This is generally preferred method. This method would normally use the longest size gabion available. 3.8.3 Curves: Gabions may be formed to any radius by cutting the gabions on three sides at equally spaced points (the number of cuts and the spacing is a function of the radius), bend the uncut sides overlapping the ends and re-tie in accordance with specifications. Note: The procedure could extend over several gabion lengths in a large radius. This method would generally use the longest size gabion. 4.0 QUALITY CONTROL CREEKVIEW EROSION CONTROL AND ROADWAY IMPROVEMENTS GABION STRUCTURES COPPELL,TEXAS WALTER P MOORE PROJECT NO.

Spread concrete using short-handled, square-ended shovels, or come-alongs. 2. Placing Concrete in Forms: Deposit concrete in forms in horizontal layers not deeper than 24" and in a manner to avoid inclined construction joints. Where placement consists of several layers, place each layer while preceding layer is still plastic to avoid cold joints. 3. Consolidate placed concrete by mechanical vibrating equipment supplemented by hand-spading, rodding or tamping. Use internal vibrators of the largest size and power that can properly be used in the CREEKVIEW EROSION CONTROL AND ROADWAY IMPROVEMENTS CAST-IN-PLACE CONCRETE COPPELL, TEXAS WALTER P. MOORE PROJECT NO. C04-12007-00 03300-8 work as described in the table entitled "Range of characteristics, performance, and applications of internal vibrators" found in ACI 301. 4. Do not use vibrators to transport concrete inside forms. Insert and withdraw vibrators vertically at uniformly spaced locations not farther than visible effectiveness of machine. Place vibrators to rapidly penetrate placed layer and at least 6" into preceding layer. Do not insert vibrators into lower layers of concrete that have begun to set. At each insertion limit duration of vibration to time necessary to consolidate concrete and complete embedment of reinforcement and other embedded items without causing segregation of mix. 5. Consolidate concrete during placing operations so that concrete is thoroughly worked around reinforcement and other embedded items and into corners of forms, eliminating air and stone pockets that may cause honeycombing, pitting, or planes of weakness. 6. Maintain reinforcing in proper position during concrete placement operations. 7. Placing Concrete by Pump: If concrete is placed by using a pump, the grout used for pump priming must not become a part of the completed structure unless an engineered grout design mix and grout location are approved in advance by the Engineer. 3.5 CONCRETE CURING AND PROTECTION A. General: 1. Protect freshly placed concrete from premature drying and excessive cold or hot temperatures. Maintain concrete with minimal moisture loss at a relatively constant temperature for the period necessary for hydration of the cement and hardening of concrete. In hot, dry and windy weather protect concrete from rapid moisture loss exceeding 0.2 lb./sq. ft. x hr before and during finishing operations with an evaporation control material. Apply in accordance with manufacturer's instructions after screeding and bull floating, but before power floating and troweling. 2. Curing shall commence as soon as free water has disappeared from the concrete surface after placing and finishing. The curing period shall be 7 days for all concrete except high early strength concrete which shall be cured for 3 days minimum. Alternatively, curing times may be reduced if either of the following provisions is complied with: a. If tests are made of cylinders kept adjacent to the structure and cured by the same methods, curing measures CREEKVIEW EROSION CONTROL AND ROADWAY IMPROVEMENTS CAST-IN-PLACE CONCRETE COPPELL,TEXAS WALTER P. MOORE PROJECT NO. C04-1 2007-00 03300-9 may be terminated when the average compressive strength has reached 70% of the specified 28 day compressive strength. b. If the temperature of the concrete is maintained at a minimum of 50°F for the same length of time required for laboratory cured cylinders of the same _ concrete to reach 85% of the 28 day compressive strength, then curing may be terminated thereafter. 3. Curing shall be in accordance with ACI 301 procedures. Avoid rapid drying at the end of the curing period. B. Curing Formed Surfaces: Where wooden forms are used, cure formed concrete surfaces, including undersides of beams, supported slabs and other similar surfaces by moist curing with forms in place for full curing period or until forms are removed. When forms are removed, continue curing by one or a combination of the methods specified below, as applicable. C. Curing Unformed Surfaces: Cure unformed surfaces, by one or a combination of the methods specified below, as applicable. The Contractor shall choose a curing method that is compatible with the requirements for subsequent material usage on the concrete surface. D. Curing Methods: 1. Method 1 - Moisture Curing: Provide moisture curing by one of the following methods: a. Keep concrete surface continuously wet by covering with water. b. Continuous water-fog spray. c. Covering concrete surface with specified absorptive cover, thoroughly saturating cover with water and keeping continuously wet. Place absorptive cover to provide coverage of concrete surfaces and edges, with 4" lap over adjacent absorptive covers. 2. Method 2 - Moisture-Cover Curing: Provide moisture-cover curing as follows: Cover concrete surfaces with moisture-retaining cover for curing concrete, placed in widest practicable width with sides and ends lapped at least 3" and sealed by waterproof tape or adhesive. Immediately repair any holes or tears during curing period using cover material and waterproof tape. CREEKVIEW EROSION CONTROL AND ROADWAY IMPROVEMENTS CAST-IN-PLACE CONCRETE COPPELL,TEXAS WALTER P. MOORE PROJECT NO. C04-12007-00 03300-10 Water may be added to concrete surface to prevent drying before the cover is installed, but the surface shall not be flooded with water. 3. Method 3 — Curing or Curing and Sealing Compound: Provide curing, curing/hardener, liquid membrane-forming curing, or curing and sealing compound as follows: Apply specified compound to concrete slabs as soon as final finishing operations are complete (within 2 hours and after surface water sheen has disappeared). Apply uniformly in continuous operation by power-spray or roller in accordance with manufacturer's directions. Do not allow to puddle. Recoat areas subjected to heavy rainfall within 3 hours after initial application. Maintain continuity of coating and repair damage during curing period. Apply second coat for sealing 2 to 3 hours after the first coat was applied. Do not use membrane-forming curing and sealing compounds on surfaces which are to be covered with coating material applied directly to concrete, liquid floor hardener, waterproofing, dampproofing, membrane roofing, flooring (such as ceramic or quarry tile, glued-down carpet, vinyl composition tile, linoleum, sheet vinyl, rubber, athletic flooring, synthetic turf, or wood), paint or other coatings and finish materials. Dissipating resin type cures are acceptable in these locations. 3.6 HOT OR OTHER ADVERSE WEATHER CONCRETING A. Definition: 1. Conditions warranting hot weather concreting practices are defined as any combination of high air temperature, low relative humidity and wind velocity tending to impair the quality of fresh or hardened concrete or otherwise result in abnormal properties. If conditions cause an evaporation rate of 0.2 lb./sq. ft./hr. as calculated by Figure 2.1.5 in ACI 305R-99, then precautions shall be taken to prevent plastic shrinkage cracks from occurring. 2. The maximum acceptable concrete temperature at the truck discharge point shall be 95°F. B. Specification: Hot weather concreting practices specified below shall be followed, all or in part as required, to limit the concrete temperature at the truck discharge point to 95°F or lower. C.

Hot Weather Concreting Requirements: The following items, all or in part as required, shall be followed to limit the concrete temperature to 95°F or lower and to minimize the possibility of plastic shrinkage cracks from developing. 1. Design the concrete mixes specifically for hot weather conditions using a water reducing retarding admixture (ASTM C 494 Type D). 2. Use the largest size and amount of coarse aggregate compatible with the job. 3. Use sunshades and/or windbreaks. 4. Delay construction of indoor slabs-on-grade until the walls and roof are constructed. 5. Cool and shade aggregate stockpiles. 6. Use ice as part of the mixing water or cool the water with liquid nitrogen. 7. Limit the number of revolutions at mixing speed to 125 maximum. 8. Reduce time between mixing and placing as much as possible. 9. Do not add water to ready-mixed concrete at the job site unless it is part of the amount required initially for the specified water-cement ratio and the specified slump. 10. Schedule concrete placement for early morning, late afternoon, or night. 11. Have all forms, equipment and workers ready to receive and handle concrete. 12. Maintain one standby vibrator for every three vibrators used. 13.

CREEKVIEW EROSION CONTROL AND ROADWAY IMPROVEMENTS CAST-IN-PLACE CONCRETE COPPELL,TEXAS WALTER P. MOORE PROJECT NO. C04-12007-00 03300-13 C. Cold Weather Concreting Requirements: The following items, all or in part as required, should be followed to assure acceptable concrete in cold weather conditions: 1. Design the concrete mix suitable for cold weather. Use air entrainment (where not prohibited) and obtain high early strength by using a higher cement content, a high early strength cement - (Type III), or a specified non-chloride accelerator (ASTM C 494 Type C or E). 2. Protect the concrete during curing period using insulating blankets, insulated forms, enclosures and/or heaters. 3. Concrete cured in heated enclosures shall have heaters vented to prevent exposure of concrete and workmen to noxious gases. 4. Frozen subgrade shall be thawed prior to concrete placement and snow and ice shall be removed from forms. 5. Concrete shall be protected and cured at 50°F for seven days minimum if normal concrete (Type I cement) is used and for three days minimum if high early strength concrete (concrete with Type III cement, 100 pounds cement added per cubic yard concrete, or a non-chloride accelerator added). 6. Concrete not loaded during construction shall be protected a minimum of 3 days for normal concrete and 2 days for high early strength concrete to obtain safe form stripping strength. Concrete fully loaded during construction shall be protected for whatever time period is required to obtain the required strength as determined by nondestructive strength tests (Windsor probe, Swiss Hammer Test) on the in-place concrete. 7. Heat the mixing water and then blend hot and cold water to obtain concrete no more than 10°F above the required temperature. 8. Heat the aggregates'by circulating steam in pipes placed in the storage bins for air temperatures consistently below 32°F. When either water or aggregate is heated to over 140°F combine them in the mixer first to obtain a maximum temperature of the mixture not to exceed 140°F in order to prevent flash set of the concrete. 9. Uniformly thaw aggregates far in advance of batching to prevent moisture variations in the stockpile. 10. Cover warmed stockpiles with tarps to retain heat. CREEKVIEW EROSION CONTROL AND ROADWAY IMPROVEMENTS CAST-IN-PLACE CONCRETE COPPELL,TEXAS WALTER P. MOORE PROJECT NO. C04-12007-00 03300-14 11. Place air entraining admixture in the batch after the water temperature has been reduced by mixing with cooler solid materials. 12. Use wind screens to protect concrete from rapid cooling. 13. Maintain artificial heat as low as possible to reduce temperature stresses during cooling. 14. Avoid water curing of concrete except for parking garage structures. Apply the required curing compound to unformed surfaces as soon as possible to prevent drying of concrete from heated enclosures. 15. Delay form stripping as long as possible to help prevent drying from heated enclosures and to reduce damage to formed surfaces caused by premature stripping. 16. Provide triple thickness of insulating materials at corners and edges vulnerable to freezing. 17. Wrap protruding reinforcing bars with insulation to avoid heat drain from the warm concrete. 18. Gradually reduce the heat at the end of the heating period to reduce likelihood of thermal shock. 3.8 QUALITY CONTROL TESTING DURING CONSTRUCTION A. See Testing Laboratory Services section of these Specifications for concrete materials and cast-in-place concrete inspection and test requirements. 3.9 INVESTIGATION OF LOW CONCRETE STRENGTH TEST RESULTS A. Contractor Responsibility for Low Strength Concrete: 1. If the average of any three consecutive strength tests falls below the required fc for a class of concrete but no individual strength test is more than 500 psi below fc, the Contractor shall immediately notify the Engineer by telephone or e-mail and take immediate steps to increase the average of subsequent strength tests. 2. If any individual strength test falls more than 500 psi below the required fc, the Contractor shall immediately notify the Engineer by telephone or e-mail and take immediate steps to assure that the load-carrying capacity of the structure is not jeopardized. CREEKVIEW EROSION CONTROL AND ROADWAY IMPROVEMENTS CAST-IN-PLACE CONCRETE COPPELL,TEXAS WALTER P. MOORE PROJECT NO. C04-12007-00 03300-15 B. Additional Field Tests to Confirm Low Concrete Strengths: 1. The cost of all investigations of low-strength concrete, as defined by any individual strength test being more than 500 psi below the required f c, shall be borne by the Contractor. 2. Code-Prescribed Acceptance: The only accepted field-test _ methods of determining actual in-situ concrete strength is by the way of core tests as prescribed by ACI 318. 3. Non-Destructive Tests: If any individual strength test falls more than 500 psi below the required fc, the Engineer may request that non-destructive field tests be performed on the concrete in question using Swiss Hammer, Windsor Probe, or other appropriate methods as approved by the Engineer. Report the comparative test results of the suspect concrete under consideration with identical tests done on concrete of known strength and of the same class. The Engineer considers these test results as only approximate indicators of strength and may not necessarily, by themselves, resolve the low concrete strength issue. These test results will be considered as additional information by which to make an informed judgment. The Engineer reserves the right to accept the concrete based on the results of these approximate tests or order that core tests be taken as prescribed below. At the Contractor's option, the approximate non-destructive field-tests may be waived and core tests immediately initiated. 4. Core Tests: If, in the opinion of the Engineer, the likelihood of low-strength concrete is confirmed and it has been determined that • the load-carrying capacity of the structure is significantly reduced as a result, the Engineer may request that core tests be taken from the area in question as directed by the Engineer. There shall be a minimum of three cores taken for each strength test more than 500 psi below the required fc in accordance with ASTM C42. If concrete in the structure will be dry under service conditions, cores shall be air dried (temperature 60° to 80°F, relative humidity less than 60 percent) for 7 days before test and shall be tested dry. If concrete in the structure will be more than superficially wet under service conditions, cores shall be immersed in water for at least 40 hours and tested wet. The Contractor shall fill all holes made by drilling cores with an approved drypack concrete. 5. Acceptance Criteria for Core Test: Concrete in an area represented by core tests shall be considered adequate if the average of three cores is equal to at least 85% of the required fc and no single core is less than 75% of the required fc. If approved by the Engineer, CREEKVIEW EROSION CONTROL AND ROADWAY IMPROVEMENTS CAST-IN-PLACE CONCRETE COPPELL,TEXAS WALTER P. MOORE PROJECT NO. C04-12007-00 03300-16 locations of erratic core strengths may be retested to check testing accuracy. Load Test: If the concrete strength is not considered adequate based on core tests and the structural adequacy remains in doubt, the Engineer may order a load test as specified in ACI 318 be conducted for the questionable portion of the structure. 6. Strengthening or Demolition of the Structure: If the structural adequacy of the affected portion of the structure remains in doubt following the load test, the Engineer may order the structure to be strengthened by an appropriate means or demolished and rebuilt at the Contractor's expense.

INTRODUCTION Project Description This report presents the results of a geotechnical investigation performed for retaining wall and street improvements along Creekview Drive, adjacent to Cottonwood Branch Creek in Coppell, Texas. The project consists of construction of a new retaining wall along the lower portion of the creek bank to support two existing gravity gabion walls located between the upper creek bank and the roadway. A composite gabion structure is anticipated for the new wall. Lateral support for the new gabion structure will be provided by permanent rock anchors attached to the gabions by means of internal reinforced concrete beams. The roadway, sidewalk and railing have experienced significant distress as a result of differential movement. The project also includes repair of distressed surface improvements and subsurface utilities, as necessary. The general layout of the site is shown on the Plan of Borings, Plate 1, in the report Illustrations. Authorization This investigation was authorized by Mr. Ernest L. Fields, P.E., of Walter P. Moore & Associates, Inc. on September 7, 2012. Purpose and Scope The purpose of this investigation has been to evaluate the general subsurface and ground water conditions, to provide geotechnical parameters for design of a new composite gabion retaining wall, and to provide recommendations for remediation and reconstruction of distressed surface Project No. 18362 - 1 - November 30, 2012 r-lm a °s H1 improvements along Creekview Drive. The investigation has included drilling four sample borings, field reconnaissance, laboratory testing, engineering and geologic analyses, and preparation of the geotechnical report. Recommendations provided herein are site-specific and were developed for the project discussed in the report Introduction. Persons using this report for other than the intended purpose do so at their own risk. FIELD AND LABORATORY INVESTIGATIONS General The field and laboratory investigations have been conducted in accordance with applicable standards and procedures set forth in the 2012 Annual Book of ASTM Standards, Volumes 04.08 and 04.09, "Soil and Rock, Geosynthetics". These volumes should be consulted for information on specific test procedures. Field Investigation Subsurface conditions were evaluated by four sample borings drilled to depths of 40 to 42 feet in October 2012. The approximate locations of the borings are shown on the Plan of Borings, Plate 1 of the report Illustrations. The borings were advanced between sampling intervals by means of a truck-mounted drilling rig equipped with continuous flight augers. Samples of cohesive soils were obtained with three- inch diameter Shelby tubes (ASTM D 1587). Cohesionless soils (sands and gravels)were Project No. 18362 -2 - November 30, 2012 Fq Li F. sampled in conjunction with the Standard Penetration test (SPT) (ASTM D 1586). Unweathered shale was evaluated in-situ using the Texas Department of Transportation (TxDOT) cone penetrometer test. Delayed water level observations were made in the open boreholes to evaluate ground water conditions. The borings were backfilled at completion of field operations. Sample depth, description of materials, field tests, water conditions and soil classification [Unified Soil Classification System (USCS), ASTM D 2488] are presented on the Boring Logs, Plates 2 through 5. Keys to terms and symbols used on the logs are included as Plates 6 and 7. Elevations shown on the boring logs have been interpolated to the nearest one foot based on a topographic survey provided by the client. In addition to the borings, field reconnaissance was performed to observe the condition of the existing retaining walls and surface improvements, as well as geologic conditions exposed in the creek banks and creek bottom. Laboratory Testing All samples were returned to the laboratory and visually logged in accordance with the USCS. The consistency of cohesive soils was evaluated by means of a pocket penetrometer. Results of the pocket penetrometer readings are presented on the boring logs. Laboratory tests were performed to evaluate index properties and confirm visual classification of selected samples. Tests and ASTM designations are provided in Table 1. Project No. 18362 - 3 - November 30, 2012 t='ejU F� TABLE 1.

GENERAL SITE CONDITIONS Physiography and Surface Geology As stated above, the site is situated along Creekview Drive, adjacent to a meander bend in Cottonwood Branch Creek. The site is located along the outside bend of the creek. The outside bend is termed the "cut bank" and is subject to lateral erosion from stream action, as well as over-steepening and subsequent sloughing or global failure. The cut bank within the study area is approximately 30 to 35 feet high. The cut bank showed evidence of severe erosion, as well as sloughing and loss of trees in two areas. Soils exposed in the cut bank consisted of clay grading with depth into sandy clay, clayey sand and sand, with some basal gravel. Channel lag deposits were observed in the bottom of the channel. Project No. 18362 -4 - November 30, 2012 32t r"irgtr/ia irlm Two gravity gabion structures are present between the creek bank and Creekview Drive. The east wall is approximately 116 feet long, with a maximum exposed height of approximately 15 feet. The west wall is approximately 57 feet long, with a maximum exposed height of approximately 12 feet. It was noted that the lowest portion of the west wall is founded on poorly graded crushed rock, containing substantial interstitial void spaces. The crushed rock apparently represents gabion stone used to fill in the deepest portion of the ravine,thus reducing the height of the wall. Based on the original plans for construction of Creekview Drive, two deep ravines were present prior to construction that drained into the creek to the north. The walls were constructed within the two ravines. The original plans indicate that the east ravine was on the order of 20 feet deep at the back of the wall, and the west was on the order of 15 feet deep at the back of the wall. Based on field measurements, both gabion walls have deflected vertically and laterally toward the creek. The east wall has deflected approximately 12 inches and the east wall has deflected approximately 6 inches. The apex of the deflection in both cases corresponds with the deepest part of the ravines. At the same locations, the ground immediately behind the walls has settled up to 6 to 18 inches at the west and east walls, respectively. Filter fabric was present behind both walls. A gap of two to three inches was observed between the soil and the back of both walls. Project No. 18362 - 5 - November 30, 2012 ra FR C3 Li F. Both the sidewalk and street have also settled in these locations. The settlement appears to be proportional to the depth of the original ravines in each case. Maximum settlement of the sidewalk was on the order of 6 inches and 18 inches adjacent to the west and east walls, respectively. Maximum settlement of the roadway was on the order of five to eight inches behind the west and east walls, respectively. The magnitude of settlement tapered to one inch or less to the south, away from the walls. Some settlement of the roadway was also observed along the alignment of the storm sewer passing under the roadway along the east side of the project area. The inlet box appears to have settled as much as three inches relative to the roadway. Geology and Subsurface Conditions Subsurface conditions encountered in the borings consisted of fill and terraced alluvial soils overlying weathered grading to unweathered shale of the Cretaceous Eagle Ford Formation. Fill was encountered to depths of 1-1/2 to 13-1/2 feet. The depth of fill in the area of the two ravines corresponded closely to the depth of the ravine as indicated on the original plans at those locations. The fill consisted of brown, grayish-brown, reddish-brown and yellowish- brown, moderate to high plasticity (CL - CH) clay and silty clay with various amounts of fine sand and gravel. The upper fill immediately below the roadway appeared to have been treated with lime. The fill was generally very stiff to hard except in Boring B-3, where the fill was stiff to very stiff. The fill in this boring was noticeably more moist than in the remaining borings. Project No. 18362 - 6 - November 30,2012 The underlying alluvial soils consisted of light brown to reddish-brown, CH clay with traces of fine sand and calcareous particles. Below depths of 13 to 18 feet, the CH clay graded into light brown to light brownish-gray, sandy clay (CL) and clayey sand (SC). Yellowish-red to light brown, medium dense to dense sand (SP) was encountered below depths of 17-1/2 to 23 feet. The sand contained increasing amounts of gravel with depth. The alluvial soils extended to depths of 28 to 31 feet (approximate Elev. 487.5 to 491) and was underlain by dark gray, soft (rock classification), unweathered shale. The unweathered shale extended through the termination depths of the borings. Ground Water Based on post-drilling water level observations, ground water was present at depths of 25-1/2 to 28 feet (approximate Elev. 492 to 494) in October 2012. The ground water was perched above the unweathered shale within the alluvial soils. The gradient appeared to be toward the creek. The depth to ground water will fluctuate with variations in seasonal and yearly rainfall, as well as creek flow level. ANALYSIS AND RECOMMENDATIONS Causes of Observed Distress Settlement of the sidewalk and pavement is believed to be a result of a combination of factors including consolidation settlement of the deep fill in the two ravines, and settlement associated with lateral movement of the two gabion walls. Also, some erosion of fines behind the west wall into the crushed rock below the gabions has likely occurred. The cause of settlement of the paving above the storm drain is uncertain,but is likely the result of settlement of poorly Project No. 18362 - 7 - November 30, 2012 U F' compacted backfill above the drain. It is also possible that a bad joint or joints were present in the storm drain, causing soil to erode into the storm drain. A video of the storm drain was made, but the results of that video are unknown. A more recent video provided by The City of Coppell appears to be of the storm drain along the south side of Creekview Drive. - Gabion Structure- General It is understood that a composite gabion retaining structure will be constructed along the lower portion of the cut bank. The height of the wall should extend sufficiently above the foundations of the existing upper gabion walls to provide passive toe support of these walls. Permanent rock anchors will be used to provide lateral support for the proposed gabion structure. It is anticipated that the structure will be battered at 2V:1H, or flatter. Geotechnical design parameters associated with the proposed structure, as well as other geologic factors affecting design, are discussed in the following sections. Gabion Structure-Foundation The gabion structure should be founded at least 18 inches into unweathered shale, or 18 inches below the maximum anticipated creek scour depth,whichever is deeper. The foundation should be designed for an allowable bearing pressure of 4.5 kips per square foot (ksf) within the unweathered shale. This value incorporates a minimum factor of safety of three against a shear failure. Project No. 18362 - 8 - November 30, 2012 r-x r , E FR t is t Foundation excavations should be dry and free of all cuttings and deleterious materials prior to foundation construction. Consideration should be given to use of a minimum six-foot wide gabion mattress at the toe of the structure to limit future scour adjacent to the foundation. Gabion Structure-Lateral Earth Pressures The magnitude of lateral earth pressure acting on the proposed gabion structure will be a function of the materials within the "active zone". The "active zone" can be approximated by an included angle of 38 degrees from the vertical, projected upward from the intersection of the structure with the shale. For a battered structure, the active angle should be projected from the vertical plane intersecting the top of the structure. Considering use of site-excavated soil within the active zone, lateral earth pressures should be estimated based on an equivalent fluid pressure of .50 pounds per cubic foot (pcf). Alternatively, imported "select" fill or durable crushed stone may be used as backfill within the active zone. Considering use of"select" fill or crushed stone, as defined in the Earthwork section, lateral earth pressures should be estimated based on an equivalent fluid pressure of 35 pcf. The lateral earth pressures above are applicable for non-surcharged, drained conditions. Surcharge from slopes can be approximated as a uniform soil thickness equal to half the vertical distance between the top of the structure and the intersection of the plane defining the active zone with the upper slope. A unit weight of soil of 125 pcf and an active earth pressure coefficient of 0.36 are recommended. A maximum slope of four horizontal to one vertical (4H:1 V) is recommended above the new wall. Project No. 18362 - 9 - November 30, 2012 Whether or not the new wall is subject to surcharge from the existing upper walls will depend upon the proximity of the new wall to the foundations of the upper walls. If the foundations of the upper walls intersect a line projected at 45 degrees from the intersection of the lower wall with the unweathered shale, surcharge from these walls should be accounted for in design of the lower wall. The values above for surcharge from slopes may be considered in evaluating surcharge from the walls. As previously discussed, the height of the new wall should be such that adequate passive resistance is provided on the existing upper walls. Active earth pressure on the upper walls may be evaluated based on an equivalent fluid pressure of 60 pcf. Considering backfill using site excavated soil, passive earth pressure at the toe of the existing walls can be estimated based on an equivalent fluid pressure of 320 pcf. Prior to backfilling the toe of the west wall,the voids in the existing crushed stone below the wall should be filled with a free-flowing grout. The values above do not contain specific factors of safety. Factors of safety, if applicable, should be integrated into the structural design. Gabions are considered to be free-draining. Therefore, development of hydrostatic pressure behind gabion structure should be limited. A filter fabric, such as Mirafi 140-N or equal, should separate the gabions and the general fill. Filter fabric is recommended to limit loss of fines through the gabions. Project No. 18362 - 10 - November 30, 2012 Frg t-Imtrt .esmtrt A minimum two-foot thick compacted clay cap should be constructed above the general fill to limit surface water infiltration behind the structure. If granular soil is utilized as backfill behind the structure, the clay cap should be separated from the granular soil by a filter fabric as described above. For the new wall, resistance to lateral earth pressure will be provided by base sliding resistance between the foundation and the underlying unweathered shale. Base sliding resistance should be estimated using a coefficient of friction of 0.2. Additional lateral support should be provided by permanent rock anchors. Geotechnical parameters associated with design of the anchorage system are provided in the Gabion Structure-Lateral Support section. Gabion Structure -Lateral Support Permanent rock anchors should be used to provide lateral support to the gabion structure. Anchors may be active (post-tensioned), or passive (unstressed). It should be noted that, if passive anchors are used, some lateral movement of the structure will be necessary to develop pullout resistance within the anchors. Lateral movement necessary to develop the anchor resistance is estimated to be 3/4 inch or less. The anchors should be secured to the gabion structure by means of reinforced concrete beams formed within the gabion baskets. Consecutive rows of anchors should be offset horizontally from adjacent rows by half the horizontal spacing between anchors on a row. Project No. 18362 - 11 - November 30, 2012 nc$1. The anchors should consist of threaded, high-strength steel bars installed in pre-drilled holes and grouted throughout their full length. The anchor holes should be dry and free of all cuttings prior to installation of the bars. All components of the anchor system, including bars, anchor plates and locking nuts, should be provided with adequate corrosion protection. Each anchor should be equipped with centralizers spaced at regular intervals throughout its full length. A minimum hole diameter of four inches is recommended to provide adequate grout coverage of the bars. The anchors should be installed at an angle between 15 and 45 degrees as measured from the horizontal plane. Loads on the anchors should be transferred to the dark gray, unweathered shale. It is recommended that the rock anchors be unbonded for a minimum distance of five feet, or two feet beyond the "active" zone, whichever is greater. The unbonded length can be created by means of a bond breaker such as a grease-filled PVC sleeve. Considering dark gray, unweathered shale, the load-carrying portion of the rock anchors (bonded length) should be designed based on an estimated pullout resistance of 2.0 ksf. This value is applicable considering straight-shaft, tremmie-grouted rock anchors, and incorporates a minimum factor of safety of three against pullout. A minimum bonded length of 10 feet is recommended for permanent rock anchors. The anchor shafts should be dry and free of all cuttings and deleterious materials prior to grout placement. The shafts should be tremmie-grouted from the bottom of the shaft up. Due to the presence of ground water in the alluvial soils,use of temporary casing,pumping, or other means Project No. 18362 - 12 - November 30, 2012 FR 7=1 means may be necessary during anchor shaft construction. Close coordination of anchor shaft excavation and grout placement will limit the need for ground water control. In no case should anchor shaft excavations remain open for more than six hours prior to grout placement. Project No. 18362 - 13 - November 30, 2012 1=; ialzr r-r r,-- ez r ,r, uFo Gabion Structure-Abutments The,abutments of the retaining structure will require special consideration to account for future erosion. It is recommended that the abutments be turned back into the slope for a minimum distance of 10 feet. The transition should be accomplished by means of as large a radius of curvature as possible, and should conform to the contours of the adjacent slope in order to limit the creation of"knick points" which create turbulent flow and accelerate erosion. Unprotected slopes beyond the downstream end of the structures should be re-vegetated as soon as possible after construction. Consideration should be given to use of an erosion control fabric to limit erosion during the re-vegetation process. Maintenance of the abutment slopes should be anticipated due to the potential for continued erosion in this area. Storm Drain It is anticipated that the existing storm drain under the roadway will be removed and re-routed to the north, into the creek. The existing utility trench should be backfilled in controlled lifts as outlined in the Earthwork section. Temporary excavations should be designed to meet OSHA requirements. Subsurface soils should be classified as "Type B" cohesive soils. Roadway and Flatwork Repair of the distressed roadway and flatwork should be performed after the new gabion wall is constructed and the existing walls are stabilized. Once this is accomplished, the affected pavement and sidewalk should be demolished. The soils should then be excavated to a Project No. 18362 - 14 - November 30, 2012 L� CX minimum depth of five feet. The excavation should extend to the back of the existing gabion walls on the north side. Any filter fabric damaged during excavation should be removed and replaced. The exposed subgrade below the roadway in the bottom of the excavation should be proofrolled with a loaded dump truck. Any soft or loose zones identified by proofrolling should be excavated to firm subgrade. Proofrolling should not be performed within 15 feet of the back of the existing gabion walls. The exposed subgrade in the bottom of the excavation should be scarified to a depth of six inches and recompacted as outlined in the Earthwork section. Site-excavated soils may then be used to bring the excavation to finished subgrade for the pavement and sidewalk. Fill should be placed under controlled conditions as outlined in the Earthwork section. The pavement subgrade should be stabilized with a minimum of six percent hydrated lime. The depth of lime stabilization should meet the City of Coppell standards. A minimum depth of six inches is recommended. Lime stabilization should be conducted in accordance with TxDOT "Standard Specifications for Construction of Highways, Streets and Bridges," 2004 Edition, Item 260. Lime-stabilized soils should be compacted to a minimum of 95 percent of Standard Proctor density,ASTM D 698. Earthwork All vegetation and topsoil containing organic material should be removed at the start of earthwork construction. Excavated benches should be created so that backfill can be placed on level, continuous surfaces. Soils exposed at the surface should be scarified to a depth of 6 Project No. 18362 - 15 - November 30, 2012 fr3 Li inches and recompacted to at least 95 percent of the maximum density as determined by ASTM D 698, "Standard Proctor". The moisture content should range from optimum to +4 percentage points above optimum. Site-excavated soils, where used for fill, should be placed in maximum loose lifts of eight inches and compacted to the moisture and density requirements outlined above. "Select" fill, if utilized, should consist of uniformly blended clayey sand with a Plasticity Index (PI) between 4 and 15. "Select" fill should be placed in maximum loose lifts of 8 inches and compacted to a minimum of 95 percent of the Standard Proctor density. The moisture content should range between-2 and+3 percentage points of optimum. Crushed stone, if utilized for backfill, should consist of clean, free-draining durable rock meeting ASTM C 33, Size 67 or coarser. Crushed stone should be placed in maximum 8-inch loose lifts and compacted to a minimum of 60 percent of the relative density as determined by ASTM D 4254. Construction Observation It is recommended that a representative of this office be present to observe all construction activities in order to confirm proper bearing stratum and construction procedures. Field density tests should be performed at a minimum rate of 1 test per lift, per 150 linear feet in all compacted fills. Project No. 18362 - 16 - November 30, 2012 1= E t rx xxtt t r tt-tom Fmt CI Li Ten percent of all post-tensioned permanent rock anchors should be performance-tested to 1.5 times the design load. The remainder should be proof-tested to 1.25 times the design load. Passive anchors should be hand-tightened with a torque wrench. Performance and proof testing should be performed in accordance with guidelines provided in Federal Highway - Administration Report No. FHWA/RD-82/047. This should include creep testing as specified in the guidelines.
