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.

ITEM 1.58 - STATE AND LOCAL SALES AND USE TAXES SC-1.58 Delete Item 1.58 and substitute the following in lieu thereof: 1.58 Recent legislation has removed the sales tax exemption previously provided by Section 151.311 of the Tax Code coveting 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 m-free purchase of tangible personal property which will be incorporated into and become part of a City construelion project through the use of a "separated contract" with the City. A "separated contract" is one which separates J:XCoVpealXg~149~sVecsXSuV-Cond.doc 1-39 Supplem.entary Conditions of the Agreement 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, from 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 fumish a breakdown (per item) of 1) materials incorporated into the project; and 2) labor, equipment, supervision and materials not incorporated into the project. · -40 Supplem.entary Conditions of the Agreement SECTION 2 SPECIFIC PROJECT REQUIREMENTS .T:\CoppellX96149x~peca~Sec-2.doc :2-1 SECTION 2 SPECIFIC PROJECT REQUIREMENTS The construction specifications which apply to this project are the Standard Specifications for Public Works Construction - North Central Texas with latest Amendments prepared through the North Central Texas Council of Govemments (C.O.G.).

Coppell, Texas ._ Thru Shimek, Jacobs & Finklea INTRODUCTION -- In accordance your authorization of our proposal dated 22 October 1996, we have completed a Geotechnical Investigation for a proposed 2 Million Gallon Elevated Storage Tank at Wagon Wheel Ranch Park located near the intersection of Northpoint Drive and Royal Lane in Coppell, Texas. ' PURPOSE AND SCOPE The purpose of this investigation was to develop specific geotechnical data at the location of the proposed new elevated storage tank by means of subsurface exploration " and laboratory testing and develop recommendations for the design and construction of foundations for the structure. The scope of this investigation includes the accumulation of basic geotechnical data regarding existing subsurface conditions in the area of the proposed tank. The necessary data were gathered by means of subsurface exploration and laboratory testing. Engineering evaluation of the resulting data was accomplished to provide specific recommendations to aid in the design and construction of foundations for the proposed project. HENLEY JOHNSTON & ASSOCIATES, INC. ~ I, engineerin9 9eoscien~e corts,,~ar~s -1- SUBSURFACE INVESTIGATION Subsurface conditions at the proposed site of the new 2 Million Gallon Wagon Wheel Ranch Park Elevated Storage Tank were investigated by two (2) NX-size core borings drilled to depths of approximately 80 to 90 feet below existing ground surface. These borings were located on the site by Shimek, Jacobs & Finklea. Originally three borings were planned at the site. Because of difficulties moving at the site, due to inclement -weather, and the similarity of the first two borings drilled, it was determined that the third ,. boring was not needed to characterize the site, and, consequently, only BOring Nos. 2 and 3 were drilled. The borings were drilled using a truck mounted rotary drilling rig ... which employs dry auger. ing techniques to advance the borings to the top of rock and wash rotary drilling in the rock materials. Sampling techniques were dependent upon the type of material encountered. Samples of cohesive overburden materials encountered in the borings were obtained utilizing a thin-walled, seamless, Shelby-tube sampler advanced into the ground by means of a " continuous ra:pid thrust from a hydraulic ram on the drilling rig. This technique generally conforms with ASTM D 1587. Samples from granular strata were obtained utilizing procedures of the Standard Penetration Test (ASTM D 1586). This sampling technique employs a 140-pound hammer, dropped 30 inches, to drive a 2-inch O.D. split-barrel sampler into the soil. The sampler is initially seated six inches and then driven in two additional six-inch · increments while recording the number of blows in each increment. The total number of blows in the last two six-inch increments, the "N" value, is recorded on the enclosed ',Log of Boring" illustrations. Refusal is defined as 50 blows in any one increment with 6 inches or less advancement of the sampler, 100 total blows or 10 blows with no advancement of the sampler. The primary rock formation encountered in the borings was sampled with a double-tube core barrel fitted with an appropriate cutting bit. ~" HENLEY JOHNSTON & ASSOCIATES, INC. =~ I, engheering 9eoscience cortsulmr~s -2- The samples were extracted from the sampling devices in the field. All soil samples and selected rock samples obtained from the borings were encased in polyethylene plastic to prevent changes in moisture content and to preserve in situ physical properties. Samples were classified as .to basic type and texture in the field, labeled as to appropriate boring number and depth, and placed in core boxes for transport' to the ,_ laboratory. ,, Both borings were drilled dry to the top of rock. Upon completion of each boring, the drill water was bailed from the borehole. The boreholes caved at about 43 to 44 feet .-- below existing grade and were dry to that depth. This is noted on the individual "Log of Boring" illustrations at the bottom of each log. LABORATORY TESTING ~-' Samples received in the laboratory were visually classified by an experienced / Engineering Geologist. All soil samples were classified in accordance with the Unified ~ Soil Classification System; rock core was classified using standard geologic terminology. Terms and symbols used on the boring logs are described on the enclosed sheet *" entitled "Legend, Lithology, Soil Consistency &Relative Rock Hardness." "' To aid in the classification process, Atterberg Limits, Moisture Content, Grain Size Analysis and Unit Dry Weight tests were performed on representative samples. ·-All of the above test data are summarized on Plate 2. Atterberg Limits also are presented graphically on the Plasticity Chart on Plate 3. The strength of each cohesive sample was estimated using a hand penetrometer. The results of these estimates are recorded graphically on the "Log of Boring" illustrations. Strength properties of selected cohesive soil and rock samples were investigated by Unconfined 'Compression tests. In this test, axial load is applied to a laterally unsupported cylindrical sample until failure occurs within the sample. These test results are summarized on Plate 2 and stress-strain curves for the soil tests are presented on Plates 4 and 5. HENLEY JOHNSTON & ASSOCIATES, INC. ~ L engineerfng geOs. ciertce consul~anzs -3- SUBSURFACE CONDITIONS The specific type, depth, and thickness of materials penetrated by the borings are reflected on the "Log of Boring" illustrations. From ground surface down, the borings encountered overburden soils'of alluvial origin consisting of silty clays, silty sands and sandy gravels underlain by sandstone of the Woodbine Formation of Cretaceous Age.' From ground surface to about 18-foot depth, silty clays encountered are high plasticity soils which are subject to high volume changes with variations in soil moisture content. These clays are slightly sandy with scattered small gravel; they are brown in color and .very stiff to hard in consistency to about 6 to 8-foot depths and tan in color and hard in consistency below that depth range. In their current moisture condition, these siity clay soils have a high potential for expansion. A zone of silty clay, sandy to very sandy, tan and gray in color and hard in consistency is present below the high plasticity clays to depths of about 21 to 26 feet; these clays are moderate plasticity soils. Below these clay strata are strata of granular soils that are predominantly silty sands to about 43 to 44-foot depth and sandy gravels below that depth to about 50 to 52-foot depth where the primary formation is encountered. These granular strata are indicated by the Standard Penetration Test results to be very dense in condition. In their current moisture condition, these silty clay soils have a high potential for expansion. Below the overburden soils, the primary formation, sandstone of the Woodbine Formation of Cretaceous Age, was encountered. This material is argillaceous and fossiliferous and contains thin shale partings. The sandstone is poorly to moderately well cemented, light gray in color and firm to moderately hard in rock hardness. The unweathered sandstone extends at least to the 90-foot maximum depth explored at this site. Observations of depth to groundwater at the site indicated no measurable groundwater ~, to about 44-foot depth at the time of the field investigation. Groundwater would be " anticipated to be present in the sandy gravels in the lower portion of the overburden soils. Groundwater, when present, is typically perched on the unweathered sandstone HENLEY JOHNSTON & ASSOCIATES, INC. ,,~ t, engineering geoscience consultants and found in the granular zones as well as the weathered sandstone strata. The level and quantity of groundwater should be expected to fluctuate with seasonal variations in area rainfall. FOUNDATION CONSIDERATIONS Based on the results of this investigation, we recommend that structural loads for the proposed elevated storage tank be transferred into the unweathered, light gray sandstone of the Woodbine Formation by means of straight-walled, aug~-excavated, cast-in-place, concrete shafts. We recommend that these piers extend at least two feet into the light gray unweathered sandstone. Alternatively, structural loads may be supported by dri!led-and-underreamed piers, based at about 20-foot depth in the silty, sandy clays present above the granular strata at this site. Recommendations for both foundation types are presented in subsequent paragraphs. Straight-Walled Concrete Piers For design of straight-walled concrete piers, allowable load intensities for end bearing and side shear stress transfer in the light gray unweathered sandstone have been developed utilizing equations derived from the Theory of Elasticity, average strength values from Unconfined Compression tests; a factor of safety of 3; and may be summarized as follow: Stress Transfer End Bearing. = 6.5 tsf Side Shear, Compression -- 2.0 tsf Side Shear, Tension = 1.0 tsf Side-shear stress transfer is limited to the perimeter portion of the pier shaft in intimate contact with the unweathered limestone formation, below the base of any temporary casing required to install the shafts. For design purposes, the upper two feet of the gray limestone should be neglected in capacity computations. . HENLEY JOHNSTON & ASSOCIATES, INC. ~,, L .... enO, ineerb~ 9eoscience corts-l~anr~ -5- The side shear values provided are directly applicable only for isolated drilled shaft foundations separated in plan by a clear distance of at least two shaft diameters. If this spacing cannot be maintained, this office should be contacted so that additional studies can be accomplished and reduced design values developed. We estimate that settlements of straight shaft piers based in the hard, light gray, unweathered sandstone will be small fractions of an inch. The settlement will occur largely as elastic deformation and should be substantially complete at'the end of construction. Drilled-and-Underreamed Piers We recommend that drilled-and-underreamed piers based in the hard silty, sandy clays at about'20 feet below existing grade be proportioned using an allowable net bearing pressure determined by the following equation: -- q. = 5400 (1 + 0.2 D/B) where: '~ q. = allowable net bearing pressure, psf D = depth of base of foundation below final grade, feet "' B = diameter of foundation underream, feet " The numerical value of the term, D/B, cannot exceed 2.5. The allowable net bearing pressure determined by.the above equation includes a factor of safety of three with respect to soil shear strength. We recommend that pier underream diameters not · exceed 8 feet and that the bell to shaft ratio not exceed 2.75:1. Uplift loads on drilled-and-underreamed piers are resisted by the materials above the "" underream~ We recommend that the uplift capacity of an underreamed pier be taken as the lesser of the following two criteria. HENLEY JOHNSTON & ASSOCIATES, INC. engineerin9 geoscience consu!lanls -6- - the weight of soil in a truncated cone above the base of the underream at an angle of 35 degrees with the vertical and soil weight of 120 pcf; the difference between soil weight and concrete weight can be added to this value for the volume of the pier. ,_ the resistance of a cylinder the diameter of the underream and height equal to the depth of the underream base minus 3 feet computed as the lateral ~ area of the cylinder times a cohesion value of 2700 psf; the Weight of soil and concrete in the cylinder can be added to this value. ~,.~ Both resistance values are ultimate values. We recommend that a Factor of Safety of 1.5 ,~- be used with the first and a Factor of Safety of 2 be used with the second. --' We estimate that settlement of drilled-and-underreamed piers based on the silty clays will be less than one inch when designed in accordance with the above recommendations. Lateral Loads " Lateral loads on shafts must be considered in the overall drilled shaft foundation design. For lateral load analyses of these piers, we recommend that the coefficient of subgrade " reaction, k,, be determined for piers as the lesser of the values determined by the following equation and 26 pounds per cubic inch: k. = fz/D Where: f = coefficient of variation of lateral subgrade reaction, pci (recommend using f = 20 pci) z = depth, feet D = pier diameter, feet , HENLEY JOHNSTON & ASSOCIATES, INC. .~, t, .. . engineering 9eoscience consul~ar~s -7- Uplift on Pier Shafts The near surface clays to be penetrated by straight shaft or drilled-and-underreamed piers have a potential for expansion and could subject the piers to some uplift forces caused by expansion of the adjacent materials. We recommend that the piers be 'designed to allow for uplift from the expansive clays equivalent to about 1500 psf on the shaft area above 12-foot depth, CONSTRUCTION PROCEDURES / Each straight shaft or drilled-and-underreamed pier installation should be vertical (within ,. acceptable tolerances), placed in proper plan location and cleaned prior to concrete placement. Reinforcing steel cages should be prefabricated in a rigid manner to allow ?.. expedient placement of both steel and concrete into the excavation. It is essential that drilling of piers and the placement of both steel and concrete be completed in a .- continuous operation. In all cases, no-portion of the stratum being counted on to provide structural support should be exposed to atmospheric conditions for more than four (4) hours following the completion of drilling prior to the placement of the concrete. Based on the information from this study, we anticipate that temporary casing will be required to control groundwater seepage and/or caving of overburden soils for straight shaft installations. Casing should be available on site. If required, casing should be installed a sufficient distance into the bearing stratum to insure a watertight seal; normally a distance of I to 2 feet is adequate for this purpose. After the satisfactory installation of any temporary casing, the required shaft penetration may be excavated by machine auger within the casing in a conventional manner. if the groundwater level is above the base of any temporary casing being utilized, extreme care should be maintained at all times to insure that the head of the plastic concrete is higher than the static groundwater level outside the casing. In actual practice, it is desirable that the head of the plastic concrete be appreciably above the static groundwater level prior to breaking of the seal between the temporary casing HENLEY JOHNSTON & ASSOCIATES, INC. t, engineering geoscience consul~o~tts -8- and the bearing stratum. Once the seal is broken, the temporary casing may be slowly removed in a vertical direction only (no rotation permitted) while additional concrete is elevated to the top of the casing and placed through a tremie in order to connect with the existing concrete contained within the lower portion of the shaft. . In order to verify compliance with specifications and acceptability of the bearing stratum, a qualified and experienced geotechnical observer familiar with design details should be present at all times during each pier installation. ~,, FLOOR SLABS AND GRADE BEAMS Based on the data developed by this study, the area covered by the new elevated ,- storage tank may be underlain by silty clay soils of high plasticity and high volume change potential. Structural elements in direct contact with the ground surface may be · - subject to potential movement associated with soil moisture changes. We recommend that any soil supported slab be designed to allow for significant vertical movements. ---- Based on the soil stratigraphy and properties developed by this investigation, we-have estimated the Potential Vertical Rise (PVR) using the procedure of Texas Department of ~- Transportation Method TEX-124E. The PVR at this site is estimated to be 3.7 inches for soils in the dry condition and about 1.5 inches for the wet condition. In general, moisture "' contents of soils at this site were near the dry condition at the time of our recent site investigation and we estimate that PVR would be about 3.6 inches if those moisture "' conditions are maintained through construction. For typical grade beamS., we would recommend that a void space of at least 6 inches separate the bottom of the beam from the underlying soil surface. However, in this case, as the beam is supporting dead loads that are generally in excess of anticipated swell pressures, we recommend that the grade beam bear on the soil surface.

Subject to modification during construction, a hydrated lime content of six (6) - . percent by dry soil weight (approximately 6 pounds of lime 'per cubic foot of soil treated) - would be expected to effectively treat the subgrade soil. Soil treated with hydrated lime for use as sub-base should be compacted tO a minimum value of 95 percent of the maximum density as defined by Texas Method TEX-113E and ,_, at a moisture content at least two (2) percentage points above Optimum Moisture content. This requirement is important in minimizing post construction movement and ,-, in assuring complete hydration of the lime treated soils. ,- The following minimum pavement sections have been developed for your consideration': ASPHALTIC CONCRETE · ~- Light Vehicular Traffic (Parking Lots.

(Re-Steeh #3 at 18 inches on center) ,-- 6 inch Compacted Lime-treated Subgrade .--- Pavement grades should be established in anticipation of some vertical movement associated with expansion or contraction of the near surface clay soils. Good surface ' '~' drainage to move water rapidly off of and away from paved areas and treatment of landscaping areas to control irrigation water are necessary to minimize moisture changes ." in the clay subgrade. ' In the event reinforced concrete paving is used, it is essential that any and all reinforcing be placed so as to insure a minimum of 11/2-inches of cover. It is believed that one or more of the above suggested pavement sections may be entirely suitable for use on this project. Selection of the proper section should be based on anticipated traffic loads, frequency, and long term maintenance, as well as project economics. In general, asphaltic concrete sections have a lower initial cost, but require. more frequent maintenance than the concrete surface. '1 HENLEY JOHNSTON & ASSOCIATES, INC. engineering 9eoscience consull. art~s ~11- EARTHWORK Other earthwork recommendations are as follow: 1. Excavate and waste, or store for future use, organic topsoil and all deleterious materials'. present at the site. 2. Scarify soils exposed in fill areas and transitional areas (cut to fill ~ and fill to cut) to a depth of approximately eight (8).;::inches, add ~ moisture (if required), mix and recompact to a density of 92 to 98 ~ percent of the maximum density obtained by the Standard Proctor Compaction Test (ASTM D 698). The moisture content of the .- compacted soils should be maintained between optimum and plus four percent of the optimum value (determined from ASTM D 698) ,~ until covered by fill or floor slabs. ,'- 3.. Place fill soils in 'loose lifts not exceeding eight (8) inches and compact to the moisture/density values specified in No. 2 above. 4. If it is necessary to import material, the soils should be inorganic r- sandy clays, having a Liquid Limit less than 35 and a Plasticity Index between 6 and 15. In the event that any changes in the nature, design or location of the elevated storage tank are planned, the conclusions and recommendations contained in this report shall not be considered valid unless the changes are reviewed and conclusions of this report modified or verified in writing. HENLEY · JOHNSTON & ASSOCIATES, INC. engineering geoscience consultants The analysis and recommendations submitted in this report are based in part upon the data obtained from two borings. The nature and extent of subsurface variations at the site may not become evident until construction. If variations then appear evident, it will be necessary to reevaluate the recommendations of this report. It is recommended that the soil and foundation engineer be provided the opportunity for general review of final design drawings and specifications in order to confirm that earthwork and foundation recommendations have been properly interpreted and " implemented in the design drawings and specifications.
