This means that under certain circumstances we may be eligible for reimbursement of certain surety bond losses by the United States government under a formula established by this Act. Under this -formula the United States government pays 90% of losses caused by certified acts of ter-rorism that exceed a statutorily established deductible to be paid by the insurance company providing the bond. The Act also establishes a $100 billion cap for the total of all losses to be paid by all insurers for certified acts of terrorism. Losses on some or all of your bonds may be subject to this cap. This notice does not modify any of the existing terms and conditions of this bond, the underlying agreement guaranteed g u, by this bond, any statutes governing the terms of this bond or any generally applicable rules of law. At this time there is no premium change resulting from this Act.

In distributing the material at the site of the work, each piece shall be unloaded opposite or near the place where it is to be laid in the trench. Coated and wrapped pipe shall be handled in such manner that a minimum PS #10 RESERVOIR 02510-4 8/27/2003 _a amount of damage to the coating will result. Damaged coating shall be repaired in a manner satisfactory to the Owner's Representative. F. Pipe shall be placed on the site of the work parallel with the trench alignment and pipe with bell ends shall be placed with the bell ends facing in the direction in which the work will proceed. The pipe, fittings, and accessories shall be placed along the site in such a manner as to be kept as free as possible from dirt, sand, mud, and other foreign matter. G. Pipe Laying: l . Alignment and Grade: All pipe shall be laid to the alignment as established on the ground by the Owners representative. Where grade is being maintained, as shown on the plans, the use of batter board or laser beam will be required to fine grade the trench. 2. Whenever it is necessary to deflect pipe from a straight line either in a vertical or horizontal plane to avoid obstructions, to plumb valves or where vertical or horizontal curves are shown or permitted, the degree of deflection recommended by the manufacturer of the particular kind of pipe being laid and the degree of deflection shall be approved by the owners representative. 3. Field cuts on concrete pipe shall be made at all points where, in the opinion of the Owners representative, it is necessary to preserve alignment or proper stationing for field connections. Proper care shall be taken to preserve the interior and exterior linings. After the spiral winding has been exposed, the winding shall be tack welded before being cut. In cutting the spiral winding sufficient length shall be allowed to permit a later winding of at least one- half turn on the bell or spigot ring. Where steel cylinder pipe is cut, the work shall be done in such a way as to allow a snug fit with the bell or spigot ring. A continuous weld shall be run on both the inside and the outside of the ring. The free end of the spiral shall then be wrapped around the ring and its end shall be welded to the ring by running a weld along each side of the rod for a distance of at least six inches. The entire cutting operation shall be done under the direction of a representative of the pipe manufacturer. 4. Whenever the deflection in a joint exceeds the maximum deflection recommended by the manufacturer, the Owners representative may require that the joint be welded. Joints on pipe installed in encasement pipe shall be tack welded or completely welded. H. Manner of Handling Pipe and Accessories into Trench: After the trench grade has been completed, all bell holes dug and the grade inspected, the PS #10 RESERVOIR 02510-5 8/27/2003 ri, L pipes and accessories may be placed in the trench. All pipe, fittings, and valves shall be carefully lowered into the trench piece by piece by means of derricks, ropes, or other suitable tools or equipment, in such a manner as to prevent damage to the material in any way. Under no circumstance shall pipe or accessories be dropped or dumped into the trench. I. Cleaning and Inspection: Before lowering into the trench, the pipe shall be again inspected for defects and cast iron pipe while suspended shall be lightly hammered to detect cracks. Any defective, damaged, or unsound pipe or other incidental materials shall be rejected. All foreign matter or dirt shall be removed from the inside of the pipe, bells, spigots, or parts of the pipe used in forming the joint before the pipe is lowered into the trench; and it shall be kept clean by approved means during and after laying. The open end of the pipe in the trench shall be plugged when pipe is not being laid. J. Laying and Jointing Concrete Cylinder Pipe: 1. Just before making the joint, the gasket and the inside surface of the bell shall be lubricated with film of soft vegetable soap compound (flax soap) to facilitate telescoping the joint. The rubber gasket shall be stretched uniformly as it is placed in the spigot groove to insure a uniform volume of rubber around the circumference of the groove. 2. Metal spacers of proper thickness shall be held on the inside shoulder of the bell to provide the proper space between abutting ends of 27 inch and larger pipe. The joint shall be telescoped by pulling directly along the centerline of the pipe so that the spigot enters squarely into the bell. After the spigot has been telescoped into the bell, the bell end of the pipe being laid shall be moved in accordance with the plans to secure proper grade and alignment. After the joint is in place, a thin metal feeler gauge shall be used to check the position of the rubber gasket around the circumference of the joint. 3. After the spigot has been telescoped into the bell, the joint checked and found satisfactory, a burlap wrapper shall be placed around the pipe covering the joint. The burlap -type wrapper shall be hemmed at each edge to allow threading with a steel strap to securely fasten the wrapper around the pipe by means of a stretcher and sealer. The length shall be that required to encircle the pipe, leaving enough space between the ends at the top to allow the cement mortar to be poured. The entire joint shall be poured with cement mortar and rodded or agitated to eliminate voids and settlement. Any joint showing shrinkage or excessive cracking shall be cleaned and remade. In hot weather, additional measure may be required to obtain the best quality of joint, such as additional wet PS #10 RESERVOIR 02510-6 8/27/2003 burlap, curing membrane, or immediate careful and well -controlled backfilling of the joint with damp earth. 4. Where size permits, the inside joint recess shall be filled from the inside with mortar and finished off smooth with the inside of the pipe by hand troweling after the pipe has been backfilled. The inside joint recess on pipe smaller in diameter shall be filled by buttering the bell end with mortar immediately prior to placing the pipe together. After the joint is engaged, the interior of the smaller diameter pipe shall be swabbed to smooth and clean the joints. 5. At times when pipe laying is not in progress, the open ends of pipe shall be closed by approved means, and no trench water shall be permitted to enter the pipe. K. Laying and Jointing Ductile Iron Pipe: 1. The gasket seat in the socket, the rubber gasket and the plain end of the pipe to be laid should be wiped clean. After placing a length of pipe in the trench, the plain end of the pipe should be then aligned and started into the socket so that it is in contact with the gasket. Sufficient force then must be exerted on the entering pipe so that the plain end is moved past the gasket and makes contact with the base of the socket. The joint maybe deflected but never to exceed manufacturer's recommendations. 2. Unless otherwise directed, pipe shall be laid with bells facing in the direction of laying; and for lines on appreciable slopes, bells shall, at the discretion of the Owners representative, face up grade. 3. Cutting of pipe for inserting valves, fittings or closure pieces shall be done in a neat workmanlike manner without damage to the pipe or the cement lining. 4. The jointing shall be completed for all pipe laid each day, in order not to leave open joints in the trench over night. At the times when pipe laying is not is progress, the open ends of pipe shall be closed by approved means, and no trench water shall be permitted to enter the pipe. 5. No pipe shall be laid in water, or when the trench conditions or weather is unsuitable for such work, except by permission of the Owners representative. L. Laying and Jointing PVC Pipe: 1. The trench bottom should be constructed to provide firm, stable, and uniform support for the full length of the pipe. 2.

All issues summarized in this section are discussed In more detail in the report. This report must be read in its entirety prior to the Implementation Into design and construction of this project. 1. DPTL has performed 4 geotechnicai borings at this site. The site is located In the Northwest quadrant of the intersection of 82"d and Memphis Street In Lubbock, Texas. Three (3) of the borings were extended to a depth of 30 feet and one (1) was extended to a depth of 70 feet below existing ground surface which is believed to be approximately 32371 . 2. According to the United States Department of Agriculture the subsurface material encountered at this site should be an Estacado Urban Land Complex. Estacado soils have a surface layer of friable, moderately alkaline, brown clay loam about 16 Inches thick. The Urban land consists of residential and commercial buildings, driveways, streets and sidewalks. Surface runoff Is high because of the works covering the area. The potential is high for urban use. Corrosivity to uncoated steel and low strength are the most limiting factors but are easily overcome by good design and careful Installation. The majority of the soils in the top 2' of the borings possess plasticity index (PI) values below 15 therefore could be utilized for select fill if the PI is verified. 3. Groundwater was encountered at this site in all four (4) borings at the 20' depth. Groundwater at this depth or shallower Is not uncommon for this area due to the lake that exists to the North/Northwest. 4. Laboratory test results Indicate that the soils encountered in the upper 5' of the four (4) borings are moderate In Plasticity. A potential vertical rise (PVR) up to 3/a" in the top five (5) feet of existing soils has been estimated for the current conditions and anticipated for the proposed City of Lubbock Water Reservoir Project if no modifications are made to the existing soils. These and other design and construction recommendations are discussed In more detail in the attached report. nurN.nrrrngnn Tminr i nnnanTnu mr r GEOTECHNICAL EXPLORATION CITY OF LUBBOCK WATER RESERVOIR AT 82ND AND MEMPHIS AVENUE Lubbock, Texas 1.0 INTRODUCTION 1.1 Project Information This report presents the findings of our subsurface exploration and geotechnical engineering evaluation for the proposed water reservoir project. The structure will be constructed in the Northwest quadrant of the Intersection of 82"a and Memphis Avenue in Lubbock, Lubbock County, Texas. At this site exists an underground water reservoir that we believe Is approximately 24, below grade at approximately elevation 3213'. We believe this structure would be demolished and completely removed before the pit Is backfilled. At this time a wire wound concrete reservoir will be constructed on this site. It Is our understanding that the structure Will be an above ground water storage tank that has a 5-6 million gallon capacity. The structure Itself will be 200' in diameter. The side walls will be 30' tail with a 20' dome roof. 1.2 Purpose of Exploration The objective of this exploration was to explore the general subsurface conditions at the site and to evaluate and analyze these conditions as they relate to foundation construction. 1.3 Scope of Exploration The scope of work Included a site reconnaissance, soil test boring, sampling, laboratory testing, engineering evaluation of the field and laboratory data, and the preparation of this report. Specifically, this report addressed the following: 1. Description of the existing site conditions 2. A description of the area, site evaluation and subsurface conditions 3.

Ifs. — I _. 2.0 INVESTIGATION PROCEDURES 2.1 Visual inspection The site and surrounding areas were evaluated visually by a DPT employee. The observations were utilized during the determination of recommendations and in relating known geologic conditions in the area to site specific conditions. 2.2 Scope of Field investigation Four (4) geotechnical borings were advanced at the approximate location shown on the attached Borings Location Map (Figure 4 In Appendix A). The depths of the borings are 30 and 70 feet below existing ground surface. No exact sea -level elevations were given at the time of this report but it is our belief that the existing elevation is approximately 32371. All four borings were drilled at what we believe Is the outer edge of the circular proposed reservoir. The borings were located In the field by a DPT representative from a map provided by City of Lubbock personnel. There 'were no restrictions encountered by underground utilities as they were located before drilling began by Dig TESS as arranged by DPT personnel. Please note, the borings were advanced In the approximate locations they are shown on the Location of Borings Map as directed by City of Lubbock personnel. Representative soil samples of the subsurface materials were obtained utilizing a split -spoon sampling method as per ASTM D-1586. A standard 2- inch O.D. split -spoon sampler was driven 18-inches Into subsurface materials using a 140-pound hammer with a fail of 30-Inches to obtain relatively disturbed samples at selected depths during drilling procedures. The number of blows to drive the split -spoon sampler the final 12-inches of penetration, known as N-value, is recorded in the appropriate column on the logs. Unconfined compressive strength tests were performed on selected samples. The samples were removed from the sampler and placed In sealable plastic bags to prevent moisture loss or gain and to be used in further testing. The borings were backfilled with on -site materials upon completion. The soil classifications and descriptions are based on visual examination, as outlined in ASTM D-2487-92, the unified Soil Classification System in conjunction with Munsell Soil Color Charts, and should be considered approximate. Subsurface materials encountered are recorded on the Boring Log, which depict soil classifications, descriptions, and penetration resistance and are Included in Appendix B. 2.3 Scope of Laboratory Testing Minus #200 sieve analysis (ASTM D 1140-92), existing moisture content (ASTM D 2216), particle size distribution (ASTM D422) and Atterberg limit tests (ASTM D 4318-84) along with unconfined compressive strength tests (ASTM D2166) were performed on selected samples to assist in classification of subsurface materials and determination of engineering characteristics of the materials. All laboratory results are described on the Log of Borings located In Appendix B. .2- I (IUGSS.P[:1GASnn 1[Si nr I finnflnino ! Illr �-1 3.0 SITE AND SUBSURFACE CONDITIONS 3.1 Site Descriptions The site of this project is located in the Northwest quadrant of the intersection of 82"d Street and Memphis Avenue in Lubbock, Lubbock County, Texas. The proposed structure will be a water reservoir storage tank. Ground vegetation at the project site is abundant. The site Is a grassy landscaped area surrounding a tennis court that Is constructed on top of the existing underground reservoir that will be removed. The topographical conditions at the site consist of a relatively level area for approximately 20' outside of the tennis court. The ground is level from the East side of the tennis court and remains so all the way to Memphis Street. On the West side it is level for approximately 20, before a significant grade change occurs. This grade change results In a drainage canal that runs to the North to the lake. 3.2 Subsurface Conditions All data interpreted from the geotechnical borings are detailed In the Log Of Borings located In Appendix B. As previously mentioned, the location of the test borings are pictured on Figure 3 in Appendix A. The subsurface conditions discussed In the following paragraphs and those depicted in the Log of Borings are based solely on the information obtained from the geotechnical borings drilled at the site and represents an estimate of the subsurface conditions based on interpretation of the borings data using normally accepted geotechnical engineering judgments. The soil borings encountered Clayey Sand, Sandy Lean Clay and Silty Sand. These strata are discussed in the following paragraphs. Excessive moisture contents existed in all four borings at and below the 20' depth after water was encountered. 3.2.1 Clayey Sand Clayey Sand was encountered in boring #1 from the surface to the 7' depth and again from the 18 to 27' depth, in boring #2 from the surface to the 5' depth and again from the 20 to 27' depth, in boring #3 from the surface to the 10' depth and again from 20 to 27' depth and in boring #4 from the surface to the 15 depth and again from the 19 to 27' depth. The color of this soil is Pinkish White with Rock, Pink, Reddish Brown, Light Brown, Brown and Pinkish Gray. The plasticity index (PI) of the Clayey Sand ranges from 12 to 19 which results in a degree of plasticity of moderate, the moisture contents range from 7.6 to 27.9 percent, and the density varied from medium dense to very dense. -3- num.nCipw ifennr i nnnnninnu inr UVI.VU I LI-QUIP ILUIIIIV UIUVIU11VIW. IIIU. The Standard Penetration Test values (blow counts) for the Clayey sand existing In the borings ranges from 11 blows for 12 Inches of penetration to 90 blows for 9 inches of penetration. 3.2.2 Sandy Lean Clay Sandy Lean Clay was encountered in boring #1 from the 7 to 18' depth, In boring #2 from the 5' to 20' depth, in boring #3 from the 10' to 29 depth and in boring #4 from the 15' to the 19' depth. The color of this soil ranges from Light Brown with Rock, Pink, Pinkish White, Light Reddish Brown and Very Pale Brown. The plasticity index (PI) of the Sandy Lean Clay ranges from 11 to 18 which results in a degree of plasticity of moderate, the moisture contents range from 10.3 to 20.0 percent, and the consistency varied from stiff to hard. The Standard Penetration Test values (blow counts) for the Sandy Lean Clay existing in the boring ranges from 9 blows for 12 inches of penetration to 36 blows for 12 inches of penetration. 3.2.3 Silty Sand Silty Sand was encountered in boring #1 from the 27 to 70' depth and in borings #2,3 and 4 from the 27 to 30' depth. The color of this soil is Very Pale Brown. The plasticity index (PO of the Silty Sand ranges from NP to 3 which results in a degree of plasticity of none, the moisture contents range from 18.1 to 34.8 percent, and the density was very dense. 3.2.4 Groundwater As mentioned previously, groundwater was encountered at the 20' depth In the four (4) borings. Groundwater at this depth is not uncharacteristic for this area since a lake exists to the North/Northwest of the site. It is unlikely though that groundwater would be encountered during the construction of a mat or ring foundation at approximately elevation 3237. The amount of groundwater is expected to vary with seasonal rainfall, other climatic conditions, surface runoff, permeability of on -site soils, continuity of pervious soils, irrigation practices, and other factors. These observations do not constitute a groundwater study nor was such a study authorized as a part of the scope of investigation only as monitored during and after drilling. 3.2.4 Frost Depth The design frost depth for Lubbock County, Texas is 18 inches. 3.2.5 Seismic zone The location of this project is in a Zone "0" area which is an area of no damage.

I L 3.2.6 Shrink/Swell Potential The tendency for a soil to shrink and swell with changes In soil moisture content is a function of the clay content and the type of clay material. These are reflected in soil consistency as Indicated by the liquid limit and plasticity index of the Atterberg Limits Tests. A generalized relationship between shrink/swell potential and the soil plasticity index (P.l.) is shown as follows: General Relationship Between P.I. and Shrink/Swell Potential P.I. Range Shrink/Swell Potential 0 t01 s Low 15 to 25 Medium 25 to 35 High >35 Very High The soils at this site possess a low to medium shrink/swell potential. 4.0 DESIGN RECOMMENDATIONS The following design recommendations have been developed on the basis of the previously described project characteristics and subsurface conditions encountered. If there are any changes In the project criteria, this office should be notified immediately and a review made by DPTI to determine if any modifications in our recommendations would be required. The following conclusions and recommendations are based on our observations at the site, interpretation of the field data obtained during this exploration, and our experience with subsurface conditions. Subsurface conditions in unexplored locations may vary somewhat from those encountered in our Investigation. If the structure location, Is changed from the above understanding, we request that we be notified immediately so that we may reevaluate our recommendations. 4.1 Proposed Construction Our understanding and knowledge of this project is based on conversations with Mr. Terry Baker Of City of Lubbock Public Works Engineering. We were Issued a small portion of the site plan of this project before drilling was started. It is our understanding that the existing water reservoir will be demolished, removed and the excavation backfilled. it is our belief that the proposed reservoir will only cover half or less of the backfilled area in the North -South direction. In the East-West direction we believe the proposed reservoir will extend past the backfilled edge on the West side but inside the backfilled edge on the East side. It is recommended that any area under the proposed reservoir location that is not already part of the backfill process be over excavated a minimum of fourteen (14) feet and be backfilled as part of the original backfill process. This is recommended In order to provide uniformity under the foundation. This backfill process should be performed as described In sections 5.2 and 5.3 (Subgrade and Foundation Preparation) of this report. Information concerning structural loads was not provided at the time this report was prepared but are assumed to be heavy. -5- nurm.nrTrncnn Train i nnnnnTmi im VVLVV I LILINlVII Iw1111V LIIUUfIIOVIk\ll nlu. i Swelling Characteristics: An estimate of the magnitude of the possible ground surface movement caused by shrinking and swelling of the clay containing soils has been made through the use of the potential vertical rise (PVR) procedure. As previously mentioned PVR expected for this site Is of the magnitude of up to W. The anticipated ground movements due to the swelling of the underlying soils at the site were estimated assuming dry moisture conditions. The remove and replace scenario will help reduce the PVR by means of the compactive effort. Any additional select fill material placed above elevation 3237' will also help in reduction of the PVR. we estimate PVR values will be reduced by about 1/4" for each 1 foot of select fill placed above the 3237' elevation. This method utilizes correlations between Atterberg Limits (PI) test data to estimate the swell potential and as such, the result must be considered as giving approximate values of the shrink -swell potential. The moderate clays In the borings have a medium potential for volume change with changes in the soils moisture content. The volume change Is normally evidenced by the heaving and cracking of concrete slabs. The Potential Vertical Rise (PVR) at this site is on the order of %" assuming the soils re allowed to increase In moisture content from a relatively dry condition to a relatively wet condition over a depth of 10 feet. It is not uncommon to assume differential movement as half of the PVR. Due to the moderately plastic nature of on -site soils some of which may be left in place (perimeter of the foundation) consideration should be given to these soils to reduce their shrink/swell potential if the estimated PVR is too high for design. Controlling the moisture content variation of a soil will therefore reduce its variation in volume. A number of measures may be Increased to attain a reduction in subsoil moisture content variations, thus reducing the shrink/swell potential. Some of the measures are listed below: 1) During construction, a positive surface drainage scheme should be implemented to prevent ponding of water on the subgrade. 2) The foundation subgrade should not be allowed to dry out; foundation backfili should proceed as soon as possible after construction to minimize changes In the soils natural moisture. 3) Positive surface drainage should be maintained around the foundation to transmit water away from the foundation perimeter. Proper grading and drainage in the foundation area to prevent ponding of water Is essential. In no Instance should water be allowed to pond in the foundation vicinity either during or after construction. The final ground surface should be sloped down and away from the edge of the foundation at a minimum of five percent (SM slope (six inches drop in ten feet of run) to make sure water drains away from the foundation area during the life of the project. The slope should extend at least ten feet from the foundation perimeter. 4) Utility trenches should be backfilled with on -site materials to reduce the potential of the trenches acting as aqueducts and transmitting water beneath the structure due to excessive surface water Infiltration. -6- nurcc.nrTr9Qnn Kum i nnnnm ou mr 1-4 5) Trees or other vegetation whose root systems have the ability to remove excessive moisture from the subgrade and foundation soils should not be planted next to the structure. Planted and landscaped areas adjacent to the structure should not be covered with an Impermeable sheeting, commonly used to reduce weed growth. Trees and shrubbery should be kept away from the exterior edge of the foundation element a distance of at least equal to 1.5 times their expected mature height. Trees can remove soil moisture through their root system, therefore creating significant soil moisture differences between the structure and consequently aggravating expansive soil activity. Root growth beneath a foundation can also cause damage by Pushing against a foundation element. '6) Differential movements should be expected between the foundation and adjoining structures, such as sidewalks. Flexible joints should be used which account for such movement without adversely affecting the aesthetics and integrity of the joint and without allowing stress transfer. 7) Sloping of the surface of the fill or backfill during construction to promtote run-off of rain water to drainage features until final lift is placed. 8) Utilities which project through slab -on -grade or slab -on -fill slabs should be designed with either some degree of flexibility or with sleeves to help reduce the risk of damage to the utility lines as vertical movements might occur. It should be noted that these PVR estimates are indicative of the relative magnitude of probable movement under seasonal moisture changes In the soil moisture content. Movements in excess of these values may be expected if increases In soil moisture occur as the result of excessive lawn or shrubbery irrigation, broken water lines, or Improper drainage of surface water. The client is cautioned that the strength of clay soils can vary significantly with moisture content. When clays are dry the strength can be relatively high while the clays can lose their strength when they are wet. With the above mentioned Information in mind we provide the following options for design: We assume the finish floor elevation is still going to be at least 3237' since we were not presented any other elevation value. Assuming this the first option is that the backfill be placed up to elevation 32361. At this time a minimum two (2) feet thick mat foundation could be constructed bringing the finish floor elevation to 3238'. This would elevate the foundation and provide positive slope away from the foundation. The backfill against the mat foundation should be placed such that It does provide the necessary drainage slope. The In -place bearing capacity value for design at elevation 3236' should be 2000 psf. The second option would be the backfill process be continued until elevation 3237' Is reached. At the time select fill material should be placed as described in section 5.3 of this report until elevation 3238' is achieved. The next step would be to trench a ring footing a minimum of two (2) feet deep. once again the In -place bearing capacity value at elevation 3236' is 2000 psf. -7- IL�i�'�I�i�1!j�ITlj(��iflTlli!T!TIT!T!T(IT�I►�IIT� 4.2 General Conclusions The most significant soil related factors for design of the heavily loaded structure at this site are the bearing capacities of the soil layers and their expansion. The soils present at the site are moderate in plasticity and foundations supported on these clays could be subject to movements due to moisture fluctuations in these soils. The most positive means to reduce the potential for foundation movement would be to support the proposed structures on a foundation system bearing below the freeze/thaw zone which for this area Is considered 18-inches and in the backfiiled material. It is recommended that the minimum depth for a foundation bearing depth be 24-inches below the finished exterior grade to protect against freeze/thaw only. Regardless of the foundation system used to support the proposed structure, in order to minimize the damaging effects of soil volume change caused by ponding of water, resulting In a change in moisture content, adequate grading and drainage around the structure to prevent ponding of water Is essential. All areas around the structure should be designed to prevent migration of water into the clay soils beneath the structures, and other fiatwork sensitive to movement. Irrigation of lawn around the structure should be of low quantity, with no excessive saturation or drying of soils around the foundation allowed to occur. 4.3 Recommended minimum Sampling and Testing Frequencies It is recommended that the site preparation, foundation construction and slab construction be monitored by the Geotechnical engineer or his representative. Following are recommended minimum sampling and testing frequencies. Earthwork Concrete At least one moisture -density (Proctor) test, Atterberg limits test and percent finer than #200 sieve test should be performed per each soil type such as subgrade, backfill, fill and base materials In the structure area, at least 1 density and moisture content test per 2500 square feet of surface area should be performed on the subgrade soils, and at least 1 density and moisture content test per 2500 square feet of surface area should be performed for each compacted 6-inch thick layers of fill and backfill. Testing backfill trenches should be at least 1 density and moisture content test per 100 linear feet of trench per 6-inch compacted fill thickness. A minimum of at least three density and moisture content tests should be performed in the structure area on the subgrade soils, and a minimum of at least three density and moisture content tests should be performed per 6-inch compacted thickness of fill or backfill in the building area. At least 1 slump, air content and temperature test should be performed per 50 cubic yards of each type of concrete placed each day including when concrete test cylinders are molded. -8- nu«c.onimnn iminr i nnnaamau mr F i • At least 1 set of 4 concrete test cylinders should be molded for each type of concrete per 50 cubic yards or fraction thereof placed In a day. • Each set of cylinders should be tested for compressive strength with 2 of the cylinders tested at 7 days and 2 of the cylinders tested at 28 days. • Reinforcing steel should be checked for size of placement prior to concrete placement. Foundations • The dimensions of each foundation including reinforcing steel size and placement should be checked. • The bearing material at each foundation should be checked to verify that the materials are suitable for foundation support. 5.0 CONSTRUCTION RECOMMENDATIONS All areas around the structure. should be designed to prevent migration of water into the clay soils beneath the structures, and other flatwork sensitive to movement. Irrigation of lawn around the structure should be moderate, with no excessive saturation or drying of soils around the foundation allowed to occur. 5.1 Site Preparation A. This site should be prepared by removing and clearing any existing foundations, paved areas, grass, trees, tree roots, and organic topsoils. B. The Subgrade should be proof rolled to detect local weak areas which should be excavated, processed, and recompacted in loose lifts of approximately fl- inch thickness and compacted to 95% of Standard Proctor Density (ASTM D-698- 91) and tested in accordance with ASTM Designation D 2922-91. 5.2 Subgrade Preparation A The top 9-inches of in -Place soil should be plowed or scarified, processed to near optimum moisture (+J-2%), and compacted to at least 95% of maximum dry density as determined by (ASTM Designation: D 698-91) and tested in accordance with ASTM Designation D2922-91. B. The site should be proof roiled to detect soft areas which should be removed and properly replaced. C. Subgrade should be tested by a qualified laboratory Technician under the supervision of a Registered Professional Engineer specializing in geotechnical studies. .9- nu«q.DiTiognn Tminr 1 DDnDnTnou inr 1 5.3 Foundation Preparation (Backfill and Fill) A. All select fill material should have a Plasticity Index of 4-15 and should be placed In 6-Inch maximum compacted lifts. All soil for fill should be free of large rock (larger than 21or other deleterious material and should be processed to near optimum moisture (+/-2%) and compacted to a minimum of 95% of maximum dry density as determined by ASTM Designation D698 and when tested in accordance with ASTM Designation: D 2922-91 prior to placing the next lift. The plasticity Index and liquid limit of material used as select, non -expansive fill Should be routinely verified during fill placement using laboratory tests. Visual observation and classification should not be relied upon to confirm the material to _be used as select, non -expansive fill satisfies the above Atterberg- limit criteria. B. The site should be proof rolled to detect soft areas which should be removed and properly replaced. C. Each lift should be tested by a qualified Laboratory Technician under the supervision of a Registered Professional Engineer specializing In geotechnical studies. D. The top 2-inches of fill should be sand, or other free draining soil, in the area beneath all slabs and sidewalks. The sand cushion or other free draining soil, should be damp and compacted prior to placing the fresh concrete, and should have a Plasticity Index of 8 or less. E. Structural concrete should be placed as soon as possible when the soil preparation is completed. 6.0 EXCAVATION SAFETY CONSIDERATIONS If utility trenches or other excavations extend to or below a depth of 5-foot below construction grade, the contractor or others shall be required to develop a trench safety plan to protect personnel entering the trench or trench vicinity. The. collection of specific geotechnical and the develop of such a plan which could Include designs for sloping, benching or various types of temporary shoring, is beyond the scope of the current study. Any such designs and safety plans shall be developed in accordance with current OSHA guidelines and other applicable Industry standards. The soils at the depths needed for excavation are classified as cohesive, The maximum allowable slope for excavations less than 20-feet are 1H:1V for a short term. it is Important for the design geotechnical engineer to be allowed to observe the excavations to make a determination as to the quality and competency of the soil materials. if sandy or clayey material is observed not to be stable at a 1 horizontal to 1 vertical slope or if large pockets of non -cohesive soils are encountered, the excavations may require being sloped even more gentle. If any sloughing subsidence or tension cracks are observed in the soil, the contractor should stop all work and notify the design geotechnical engineer. -10- nu[SS aragnn Tcunr IAnnnaTnnu mr 7.0 QUALIFICATION OF RECOMMENDATIONS The recommendations in this report were developed from the information obtained from the test boring which give subsurface conditions only at the specified depths and at the specified times on the boring log that there are no pre-existing deep excavated areas that have been backfilled on this site other than the backfilled reservoir area. It Is also assumed that the moisture levels encountered at this site will not be permitted to materially Increase over those shown on the tests. in addition, the laboratory test results for selected soil and. rock samples relate only to the samples tested. Rock and soil conditions at other locations may vary from the Indicated conditions and the nature and extent of the variations may not become noticeable until the course of construction. if variations do appear, it will be necessary to re-evaluate the recommendations of this report after making notes of all the variations. Also, if any changes occur in the proposed construction, including site location, this office should be notified so a review can be made. It Is important that a geotechnical engineer be retained to review the specifications and plans and also for testing and observations during the foundation construction and earthwork phases of the proposed construction to help confirm the design requirements are fulfilled. Our professional geotechnical services have been performed, our findings logged and our report prepared In accordance with generally accepted geotechnical engineering practices.

Bidder's attention is invited to the following Questions/Concerns and their respective responses: QUESTION: In General Instructions to Bidders, Article 7, Permits and Specifications, Section 01110-2, paragraph 1.05A mentions a City of Lubbock building permit for which the City will waive the fee. Are there any other known -to -be -required permits, and if so, their associated costs to be included in our bid? ANSWER: Please refer to existing specifications Section 01410, paragraph 1.01, subparagraph C. CONCERN: In General Instructions to Bidders, Article 8, Utilization of Local Business Resources, indicates that a list of local resources should be submitted with the bid. We assume - that this would be a generalized list of materials that we would obtain locally as we would not have finalized agreements with the local vendors at the time of the bid. Please clarify. RESPONSE: This paragraph is only strongly encouraging bidders to took into using local resources and, if so, list the intended utilization. CONCERN: In Bid Submittal, please clarify if the 270 days is substantially or fully complete. RESPONSE: The BID SUBMITTAL, LUMP SUM BID CONTRACT is CHANGED TO READ: "...substantially complete the project within 270 consecutive calendar days...." Bidders must submit the *** REVISED *** BID SUBMITTAL, LUMP SUM BID CONTRACT, attached. ITB#163-03/BMAd3 ITB #163-03/BM, Addendum #3 CONCERN: The attached List of Subcontractors asks whether they are minority -owned; yet we find no requirement on the use of MBE subcontractors. Please confirm that the use of MBE contractors is not required. RESPONSE: The use of MBE subcontractors is not required. QUESTION: In Specifications, 01310-1, paragraph 1.01, subparagraph 1, Does the dewatering refer to dewatering the tank or dewatering of the site? Also, when the reservoir is turned over to the contractor will it be full of water, or partially empted? ANSWER: This refers to dewatering the sight. There will be water inside the tank (the level of water inside the tank will match the ground water level). CONCERN: SPECIFICATIONS, Section 13200, paragraph 1.04,13 and Addendum #2, item A, removal of requirement for drawings and calculations to be stamped by a Texas Professional Engineer, we recommend they be stamped by a licensed professional engineer in the state of Texas. RESPONSE: Please refer to existing specifications Section 13200, paragraph 1.05, subparagraph D, added as shown on Addendum #2, item 9. CONCERN: The specification requires the tank demolition contractor to have five years experience. We assume the five years experience is in demolition and not just tank demolition. Please clarify. RESPONSE: Please refer to existing specifications Section 01410, paragraph 1.02, subparagraph B, the demolition company does not have to specialize in the demolition of water storage reservoirs. QUESTION: Is a temporary fence required around the construction site during construction? ANSWER: Yes, please refer to existing specifications Section 01510, paragraph 1.08, A. QUESTION: Will the contractor be responsible for replacing the 12 trees that will need to be removed for construction/demolition? ANSWER: Please refer to existing specifications Section 01510, paragraph 1.19, A, we are trying to save the trees. CONCERN: There is conflict between Specifications, Section 13200, paragraph 103, D, subparagraph 5, and the NOTE on Plans sheet 14; please clarify the overflow rate. RESPONSE: The overflow rate shall be set to 43 MGD as stated in the specifications. CONCERN: There is no indication of freeboard. Please confirm if a minimum of one -foot of freeboard is acceptable. RESPONSE: Freeboard is not mentioned in these drawings or specifications because this is an element of the tank design. The City of Lubbock Public Works Department will accept one -foot of freeboard if suggested by the tank manufacturer engineering staff. ITB#163-03/BMAd3 ITB #163-03/BM, Addendum #3 CONCERN: We understand from local gravel suppliers that the specified Brady Rock may not be Cost effective; nor may it be of the proper gradation to provide a stable working surface for the construction of the floor stab. RESPONSE: Section 13200- 7, paragraph 2.02, A, UNDERDRAIN GRAVEL, is CHANGED TO READ: "The under drain gravel shall meet the same criteria as the granular sub base specified in Section 13200-7, paragraph 2.01, A. QUESTION: The specifications require consideration for vandalism on the vent. We can provide a standard vandal -proof vent. Should this be forwarded to the City? ANSWER: Please refer to AWWA D110-95 and to existing specifications for vent requirements. CONCERN: Specifications, Section 13200, paragraph 3.05, B reflects a 6" thick granular sub base which conflicts with the under drain detail on Plan Sheet #10, which reflects 1'-0". RESPONSE: Specifications, Section 13200-12, paragraph 3.05, B states the !OR of the backfitt shall be a minimum 6-inch thick layer of granular material. The actual depth shall be up to the design engineer of the tank. The City of Lubbock Public Works Department will accept any depth of granular fill above 6-inches as the specifications state and the tank manufacturer engineering staff feels is adequate. QUESTION: Reference, Specifications, Section 13200-15, paragraph 3.09, G, would Fresno or Bull Float finish be acceptable? ANSWER: Section 13200-15, paragraph 3.09, G requires the tank floor to have a mechanical steel float finish. We will accept a mechanical steel float or bull float finish. CONCERN: The drawings do not indicate construction limits for this project. Please clarify. RESPONSE: Sheet 2 shows the dimensions of our lot. This is the construction limit for this project. CONCERN: On Sheet 5, the requirement to backfill under the tank to elevation 3215 is inconsistent with elevation 3214.67 as shown in the Under drain Detail on Sheet 10. RESPONSE: Elevations shown on plans are approximate. The tank floor elevation of 3216 is set; any other elevation shall be based on the tank Engineers plans. CONCERN: On Plans sheets 4, 6, and 7, in the notes it is stated that the Bypass line must be in place and operational by December 15, 2003. Please consider revising the schedule. RESPONSE: On Plans Sheets 4, 6, and 7 the required date of completion for the bypass tine shall be CHANGED from December 15, 2003 to January 15, 2004. CONCERN: On Plans Sheet 6, a proposed curtain wall and raised planting beds are indicated which are not indicated in any other drawing or in the specifications. Please confirm what is required for these items. RESPONSE: Sheet 6 shows the location of a proposed curtain wall. This line on the drawings is for location purposes only. A second construction project will begin upon completion of the tank. This contract does not include the curtain wall and planting beds. ITB#163-03/BMAd3 ITB #163-03/BM, Addendum #3 CONCERN: On Plans Sheet 6 please confirm the dimensions of the outlet tine. The outlet line entering the tank shows a 42-inch Class 150 pipe while the other drawings indicate this is a 48-inch Class 150 pipe. RESPONSE: Sheet 6 tines "c" is CHANGED to read 48-inch CL 150. QUESTION: On Plans Sheet 10, please clarify if we are to include the sump pump in this bid. If so, should it be a permanent installation that automatically lowers the ground water table? RESPONSE: Sheet 10, Sump Detail does not ask for a pump. The note says, "Manual override required to pump below elevation 3219." Note is CHANGED to read, "Manual override required to pump reservoir below elevation 3219." CONCERN: On Plans Sheet 10, we cannot find where the filter fabric is specified. Please clarify. RESPONSE: On Plans, Sheet 10, filter fabric shall be Mirafi 140n or equal. Filter fabric shalt be required under all granular sub base. CONCERN: In Addendum #1, Geotechnical, please clarify which is intended; 6" compacted lifts or 6" loose lifts as called for in Specification, Section 02315-5, paragraph 3.03, C, 1. RESPONSE: Section 02315 page 5, paragraph 3.03, C, subparagraph 1, is CHANGED to read, "not more than 6 inch compacted lifts for material compacted by heavy compaction equipment." This matches the recommendations from the geotechnical report. Additionally, Section 02315-4, paragraph 3.02, B, where it reads, "ASTM D-698 (Standard Proctor) is CHANGED to read, "ASTM D-1557 (Modified Proctor)." CONCERN: Specifications page 02315-1 indicates that the geotechnicat report overrides the specification. The report was prepared for a tank to be constructed at elevation 3257 with a bearing capacity of 2000psf. The new design indicates the tank is to be constructed at elevation 3215 with a bearing capacity of 4000psf. Suggest a revised report for a Prestressed concrete tank based on the current specification and design be supplied. RESPONSE: The tank shall be designed and built as specified. CONCERN: Regarding the geotechnical data, the ground surface elevation shown on the boring logs (3237 ft.) is approximately 5 to 8 ft. higher than the existing grade elevations shown on Sheet 4, after estimating the boring locations. Please confirm whether the ground surface elevation shown on the boring tog is correct. RESPONSE: Ground elevation at the existing reservoir is 3231.8 at the northeast corner, center of sidewalk. Dyess Peterson did not survey the elevation they took the elevation shown on their report off of an existing map. All references in the geotechnical report to 3237' elevation should be read as 3232' elevation and all other elevations shown in the report should reflect the change. 4. On Plans, Sheet 5 of 14 (referring to Specifications, Section 02315, Earthwork Requirements) please make the following changes: A. The NOTE that reads, "Apply approved backfill material as specified (02315 section B paragraph 1)" CHANGE TO READ, "Apply approved backfill material as specified (section 02315 paragraph 3.02, B, subparagraph 1)." ITB#163-03/BMAd3 ITB #163-03/13M, Addendum #3 B. The NOTE that reads, "Apply approved backfill material to grade as specified (02315 section B paragraph 2)" CHANGE TO READ, "Apply approved backfill material to grade as specified (section 02315 paragraph 3.02, B subparagraph 2) All requests for additional information or clarification must be submitted in writing and directed to: Bruce MacNair, Senior Buyer, City of Lubbock, P.O.
