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.

The CONTRACTOR 3-4 Standard Specifications Supplementary Conditions represents that no employee or officer of the City has an interest in the CONTRACTOR." ITEM 107.14 - STATE AND LOCAL SALES AND USE TAXES SC -107.14 Delete the language in Item 107.14 in its entirety and substitute the following in lieu thereof: "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 arise out of CONTRACTOR's, OWNER's, ENGINEER's, Consulting Engineer's or any other person's actions, CONTRACTOR shall promptly attempt to settle with such other contractor by agreement, or to otherwise 3-5 Standard Specifications Supplementary Conditions 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 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 108.8. 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 -107.23.2.1 Add the following new Item 107.23.2.1 immediately after Item 107.23.2: "107.23.2.1 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. This includes any and all irrigation systems, whether or not they are identified on the plans. The CONTRACTOR shall coordinate a time to video existing sprinklering systems with City of Coppell representatives to determine if functioning properly in accordance with the Contract Documents. 3-6 Standard Specifications Supplementary Conditions If it is necessary to change or move the property of any owner or of a public utility, such property shall not be moved or interfered with until authorized by the ENGINEER. 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 or ENGINEER". ITEM 108.3 - OTHER CONTRACTORS; OBLIGATION TO COOPERATE SC -108.3 Delete the last sentence of the second paragraph of Item 108.3 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 ENGINEER, 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.

Coppell Road in Coppell, Texas. We understand that the proposed building addition will be for a fire rise room and will be located on the northeast side of the existing structure. We understand that the existing structure is about 18 years old and is supported by a shallow stiffened slab -and -beam foundation system over a low PI select fill building pad. The thickness of the select fill pad is not available. 1.2 PURPOSE AND SCOPE The purposes of this geotechnical investigation were to: 1) explore the subsurface conditions at the site, 2) evaluate the pertinent engineering properties of the subsurface materials, and 3) provide foundation recommendations for the proposed new building addition. This report was prepared in general accordance with Alliance Geotechnical Group Proposal P17 -0313E dated March 13, 2017. 2.0 FIELD INVESTIGATION The field investigation consisted of drilling one (1) test boring (Boring B-1) within the vicinity of the proposed new building addition. A truck -mounted auger drill rig was used to advance the test boring and to obtain samples for laboratory evaluation. The boring was located at the approximate location shown on the Plan of Borings (Figure 1). Undisturbed samples of cohesive soils were obtained at intermittent intervals with standard, thin-walled, seamless tube samplers. These samples were extruded in the field, logged, sealed, and packaged to protect them from disturbance and maintain their in-situ moisture content during transportation to our laboratory. The relative density of the granular soils encountered in the borings was evaluated by the Standard Penetration test in conjunction with split spoon sampling. The Standard Penetration test involves driving a standard 2 inch diameter sampler a total of 18 inches and recording the blow counts and driving distances for each 6 inch or 50 blow increment. The first 6 inch ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 1 drive is for seating purposes. The results of the Standard Penetration test are recorded at the respective testing depths on the Logs of Boring. The rock formation encountered in the test boring was evaluated by the Texas Department of Transportation Penetrometer (TxDOT Cone) test. The TxDOT Cone is driven with the resulting penetration in inches recorded for 100 blows. The results of the TxDOT Cone test are recorded at the respective testing depth on the Logs of Boring. The results of the boring program are presented on the Log of Boring, Figures 2 and 3. A key to the descriptive terms and symbols used on the logs is presented on Figure 4. 3.0 LABORATORY TESTING Laboratory tests were performed on representative samples of the soil to aid in classification of the soil materials. These tests included Atterberg limits tests, percent passing #200 sieve, moisture content tests, and dry unit weight determinations. Hand penetrometer tests were performed on selected samples of the cohesive soils to provide indications of the swell potential and the foundation bearing properties of the subsurface strata. An unconfined compressive strength tests was performed on a selected sample to determine the foundation bearing properties. To provide additional information about the swell characteristics of these soils (at their in-situ moisture conditions), an absorption swell test was performed on a selected sample of the clay soils. The results of our testing program are presented on the Log of Boring (Figures 2 and 3) and on the Swell Test Results (Figure 5). 4.0 SITE AND SUBSURFACE CONDITIONS 4.1 GENERAL SITE CONDITIONS The project consists of a single story building addition to the existing City of Coppell Animal's Shelter building located at 821 S. Coppell Road in Coppell, Texas. We understand that the proposed building addition will be located on the northeast side of the existing structure. The area of the building addition is covered with grass. There is an existing small tree present near the proposed building addition. See the Boring Plan (Figure 1) for site configuration, location and aerial view. ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 2 4.2 SITE GEOLOGY As shown on the Sherman Sheet of the Geologic Atlas of Texas, the site is where deposits of the Eagle Ford Formation are present. The Eagle Ford Formation typically consists of interbedded layers of clay, weathered clay shale and shale. Soils derived from these formations are typically highly plastic clays and shaley clays exhibiting a high shrink/swell potential with variations in moisture content. The Eagle Ford shaley clay soils typically have very high soluble sulfate levels. Grapevine Creek is present just south of the subject property. Unmapped alluvial deposits from this creek consisting of clay, sand and gravel were encountered within the test boring and extended to a depth of 38.5 feet below the existing ground surface. 4.3 SUBSURFACE CONDITIONS Subsurface conditions encountered in the boring, including descriptions of the various strata, their depths, and thicknesses, are presented on the Log of Boring. Note that depth on the boring refers to the depth from the existing grade or ground surface present at the time of the investigation. Boundaries between the various soil types are approximate. 4.4 GROUNDWATER CONDITIONS The boring was advanced using hollow stem auger methods. Advancement of the boring using these methods allows observation of the initial zones of seepage. Groundwater seepage was encountered at a depth of 23 feet below the existing ground surface. Shallower groundwater levels should be anticipated if construction occurs after periods of rain. It is not possible to accurately predict the magnitude of subsurface water fluctuations that might occur based upon short-term observations. The subsurface water conditions are subject to change with variations in climatic conditions and are functions of subsurface soil conditions, and rainfall. 5.0 ANALYSES AND RECOMMENDATIONS 5.1 EXECUTIVE SUMMARY We understand that the existing structure is supported by a shallow stiffened slab -and -beam foundation system over a low PI select fill building pad. The thickness of the select fill pad is ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 3 not known. Consideration was given to using the same type of shallow foundation system to support the proposed building addition. However, the subsurface exploration at this site revealed the presence of deep highly expansive clay soils over water bearing sands. The potential for large soil swell uplift movements exists for the building addition area. Deep over -excavation would be required adjacent to the existing structure in order to reduce the potential soil swell movements to acceptable levels for a shallow foundation system and/or for a slab -on -grade floor system. As an alternative to over -excavation and moisture conditioning, chemical injection using potassium based chemical could be considered to reduce the soil swell movements of the proposed building addition. However, the existing structure would potentially be subject to differential upward soil swell heave during the injection operations. As an alternative to having to perform either deep over -excavation and moisture conditioning using an elaborate system of shoring and/or underpinning to protect the existing structure or performing chemical injection that could possibly cause differential movements of the existing structure, a structurally supported floor slab supported by piers over a minimum 12 inch void space should be considered. We understand that this type of foundation system is preferred by the owner and design team. Recommendations for this foundation system are provided within this report. We recommend that the proposed building addition be supported by cased straight shafts into moderately hard to hard dark gray unweathered shale (see Section 5.3 of this report). Moderately hard to hard unweathered dark gray unweathered shale was encountered within the test boring at a depth of 40 feet below existing ground surface. If some structural movements are acceptable, consideration can be given to supporting the proposed building addition on an underreamed belled pier foundation system (see Section 5.4 of this report). The belled piers should be founded at depths ranging from 14 to 15 feet below final pad grade and founded in very stiff to hard clay soils. Recommendations for both a cased straight shaft pier foundation system and a belled pier foundation system are provided in this report. 5.2 SOIL MOVEMENT The subsurface exploration at this site revealed the presence of deep highly expansive clay soils. The existing clay soils will have a moderate to high shrink/swell potential depending upon their existing soil moisture condition at the time of construction. Potential soil swell movement calculations were performed using swell test results, pocket penetrometer readings, and moisture content tests to estimate the swell potential of the soil. ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 4 Potential soil swell upward movements within a typical 10 foot deep "active zone" have been estimated to be on the order of 3 inches based upon current soil moisture conditions and current grades at the test boring location. It should be noted that the clay soils were generally in a moist to average moisture condition at the time of this investigation. It should also be noted that if the clay soils are allowed to significantly dry prior to foundation construction that the potential "active zone" soil swell upward movements could increase to over 8 inches. In addition, the potential for additional "deep-seated" swell exists (see Figure 5) due to the presence of deep highly expansive clay soils. The assumed "active zone" swell values are upward soil movements that could occur due to typical seasonal moisture changes and soil swelling within the upper 10 feet as measured from finished floor grade. The deep-seated swell values are additional upward soil movements that could occur due to moisture changes and soil swelling below a typical 10 foot deep "active -zone". Deep-seated swell could occur due to groundwater fluctuations or free water sources such as ponding water conditions, percolation of water in landscaped areas, leaking sprinkler lines and/or leaking utility lines that are not detected and repaired in an expedient manner. The potential for additional deep seated swell ranging from 1 to 1.5 inches exists at this site. The magnitude of deep seated swell that will actually occur will depend upon the depths of water percolation that occurs over the serviceable life of the facility. 5.3 STRAIGHT SHAFT PIERS The proposed structure may be supported by a cased straight shaft pier foundation system. The drilled shafts should be straight -sided continuously reinforced shafts that bear within the moderately hard to hard dark gray unweathered shale. We recommend that the drilled shafts penetrate the bearing stratum to the minimum depths indicated in the notes for Table 1 to develop the allowable end bearing pressure and provide anchorage resisting uplift forces generated by the expansive clay soils. Moderately hard to hard dark gray unweathered shale was encountered within the test boring at a depth of 40 feet below existing ground surface. It should be noted that actual pier depths required during construction will vary depending upon depth to the specified bearing stratum, depth of required cut and/or fill, and design penetrations into the bearing stratum. ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 5 The allowable end bearing pressure and side resistance pressures are provided in Table 1 and have been developed based on the assumption that a minimum 2 pier diameter clear spacing will be provided between piers. For piers touching, a 50% reduction in skin friction should be used. Where the clear spacing is 2D, no reduction is necessary. For a spacing between 0 and 2D, a straight line interpolation should be used. TABLE 1. ALLOWABLE BEARING VALUES *For penetrations below temporary casing into moderately hard to hard dark gray unweathered shale exceeding 2 feet as verified by the AGG geotechnical team. The skin friction values provided are for compression loading and for resistance to soil swell uplift. For other tension loads (sustained uplift), the allowable skin friction is 50% of the value indicated above. Note 1: All penetrations into moderately hard to hard dark gray unweathered shale below temporary casings may be counted on for resistance to soil swell uplift. Note 2: We recommend that a minimum shaft diameter of 18 inches be used to support the proposed building addition. **A minimum penetration of 3 feet or 1 pier diameter into moderately hard to hard dark gray unweathered shale (whichever is greater) is recommended to develop the allowable end bearing pressure. Larger penetrations will likely be required to resist soil swell uplift. Penetrations into dark gray weathered shale (identified by its softer consistency and /or by iron staining or tan colored seams) should not be counted on for the design penetrations during pier installations. The design penetrations should be counted on only for penetrations into continuous moderately hard to hard dark gray unweathered shale below temporary casing. Design penetrations should not be counted on within the cased length. The skin friction values provided are for compression loading and for resistance to soil swell uplift. For other tension loads (sustained uplift), the allowable skin friction is 50% of the value indicated above. These foundations should be subject to settlements of one-half inch. Differential settlements should be on the order of one-quarter inch. ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 6 5.3.1 DRILLED SHAFT SOIL INDUCED UPLIFT LOADS All piers will be subject to uplift loads as a result of swelling within the overlying clays. Straight shafts should be designed by the Structural Engineer with adequate penetration lengths in order to have sufficient anchorage in resisting uplift forces generated by soil swelling. The piers should have sufficient continuous vertical reinforcing steel extending to the bottom of the piers to resist the computed net uplift loads (uplift less dead load). The magnitude of the uplift loads varies with the shaft diameter, soil parameters, free water sources, and the depth of the active clays acting on the shaft. The uplift pressures can be approximated at this site by assuming a uniform uplift pressure of 2,500 pounds per square foot acting on the shaft perimeter for a depth of 12 feet. 5.3.2 DRILLED SHAFT CONSTRUCTION CONSIDERATIONS Water bearing sands are present above the bearing stratum. Therefore, temporary casing will be required and should be anticipated for all pier installations. Temporary casing should be properly seated and sealed below the seepage zone to prevent seepage into the drilled shaft excavation. Care must be taken that a sufficient head of plastic concrete is maintained within the casing during extraction. Concrete used for the shafts should have a slump of 6 inches plus or minus 1 inch and placed in a manner to avoid striking the reinforcing steel and walls of the shaft during placement. Complete installation of individual shafts should be accomplished within an 8 - hour period in order to help prevent deterioration of bearing surfaces. The drilling of individual shafts should be excavated in a continuous operation and concrete placed as soon as practical after completion of the drilling. No shaft should be left open for more than 8 hours. Soils derived from the Eagle Ford Shale Formation typically have very high soluble sulfate levels. Sulfate resistant concrete mix designs utilizing fly ash is recommended for below - grade pier concrete due to potential sulfate rich soils at this site. The mix design should include the type and amount of cement and the type and amount of fly ash proposed. Since Type V cement is not locally available, we recommend that a fly ash/ cement mix design utilizing Type II cement and 25% Type F fly ash with a low CM concentration and a maximum water/cement ratio of 0.45 (an approved equal) be used for concrete in contact with these site soils due to its resistance to sulfate attack. We recommend that additional ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 7 ACI requirements for Class 3 exposure (sulfates that exceed 20,000 ppm) be considered for implementation at this site. We recommend that these ACI guidelines be used for design. We recommend that Alliance Geotechnical Group be retained to observe and document the drilled pier construction. The engineer, or his representative, should document the shaft diameter, penetration, depth, casing installations and extractions, cleanliness, plumbness of the shaft, and the type of bearing material. Significant deviations from the specified or anticipated conditions should be reported to the owner's representative and to the structural engineer. The drilled pier excavation should be observed to verify the bottom of the excavation is dry and thoroughly cleaned of cuttings after completion. Note: "Mushrooming" should not be allowed around piers, pier caps or grade beams. 5.4 BELLED PIER FOUNDATION SYSTEM If some structural movements are acceptable, belled piers may be considered at this site to support the proposed building addition. The belled piers should be founded in very stiff to hard clay soils at depths ranging from 14 to 15 feet below existing grade as verified by AGG. The recommended allowable bearing capacity for the belled piers founded in very stiff to hard clay soils is 3,500 psf. This value contains a factor -of safety of 3.0 based on the results of geotechnical borings. A bell to shaft ratio of 2.75:1 to 3:1 is recommended. A minimum shaft diameter of 18 inches is recommended for the belled piers. Note 1: It should be specified that the belling tool be at least 1 inch smaller than the drilled shaft diameter to minimize sloughing along the drilled shaft as the belling tool is used. The depth to bottom of the completed belled pier should be equal to or slightly deeper than the depth of shaft prior to belling to verify than there is no sloughing build-up at the bottom of the belled pier. 5.4.1 DRILLED SHAFT SOIL INDUCED UPLIFT LOADS All piers will be subject to uplift loads as a result of swelling within the overlying clays. The underreamed shafts should have a base to shaft diameter ratio ranging from 2.75:1 to 3:1 to provide anchorage and to minimize the potential soil swell uplift (heave) of the belled piers. The piers should have sufficient continuous vertical reinforcing steel extending to the bottom of the piers to resist the computed net uplift loads (uplift less dead load). ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 8 The magnitude of the uplift loads varies with the shaft diameter, soil parameters, free water sources, and the depth of the active clays acting on the shaft. The uplift pressures can be approximated at this site by assuming a uniform uplift pressure of 2,500 pounds per square foot acting on the shaft perimeter for a depth of 12 feet. 5.4.2 DRILLED SHAFT CONSTRUCTION CONSIDERATIONS Groundwater seepage was first encountered within the test boring at a depth of 23 feet which is deeper than the anticipated belled pier founding depths (14 to 15 feet below final pad grade). Therefore, it is anticipated that very little if any groundwater seepage will be encountered during the installation of the 14 to 15 foot deep belled piers as long as construction occurs during dry weather periods. If minor water seepage is occurring, the pier steel and concrete should be placed immediately after belling. If excessive groundwater infiltration is encountered in any area, AGG should be contacted immediately for recommendations. Concrete used for the shafts should have a slump of 6 inches plus or minus 1 inch and placed in a manner to avoid striking the reinforcing steel and walls of the shaft during placement. Complete installation of individual piers should be accomplished within a 4 -hour period in order to help prevent deterioration of bearing surfaces. The drilling of individual shafts should be excavated in a continuous operation and concrete placed as soon as practical after belling. No shaft should be left open for more than 4 hours. Belled piers should be concreted as soon as possible after belling (within 2 hours) in order to reduce the risk for water seepage and/or caving. Soils derived from the Eagle Ford Shale Formation typically have very high soluble sulfate levels. Sulfate resistant concrete mix designs utilizing fly ash is recommended for below - grade pier concrete due to potential sulfate rich soils at this site. The mix design should include the type and amount of cement and the type and amount of fly ash proposed. Since Type V cement is not locally available, we recommend that a fly ash/ cement mix design utilizing Type II cement and 25% Type F fly ash with a low CM concentration and a maximum water/cement ratio of 0.45 (an approved equal) be used for concrete in contact with these site soils due to its resistance to sulfate attack. We recommend that additional ACI requirements for Class 3 exposure (sulfates that exceed 20,000 ppm) be considered for implementation at this site. We recommend that these ACI guidelines be used for design. ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 9 We recommend that Alliance Geotechnical Group be retained to observe and document the drilled pier construction. The engineer, or his representative, should document the shaft diameter, underream diameter, depth, cleanliness, plumbness of the shaft, and the type of bearing material. Significant deviations from the specified or anticipated conditions should be reported to the owner's representative and to the Structural Engineer. The drilled pier excavation should be observed to verify the bottom of the hole is dry and thoroughly cleaned of cuttings after completion and prior to concrete placement. Note 1: A bell checker should be used to verify that proper bell sizes are being achieved and to verify that the bell bottoms are clean of cuttings. The bell checker should be used again just prior to placement of the reinforcing cage and concrete to verify that caving of the bell has not occurred. Note 2: "Mushrooming" should not be allowed around the top of piers, pier caps and/or grade beams. Note 3: An arborist should be consulted in regards to the use of root barriers and irrigated tree wells for nearby existing trees and for future new trees in order to minimize foundation settlements caused by soil shrinkage due to long-term tree root moisture absorption. Belled piers at this site will be subjected to differential movements caused by post - construction settlement and caused by post -construction shrink/swell movements. These foundations should be subject to foundation movements of about one inch. Differential movements should be on the order of one inch. 5.5 GRADE BEAMS Grade beams supported by piers should be constructed over a void space. A minimum void space of 12 inches should be provided between the bottom of these members and the subgrade. Permanent retainer forms should be used. Structural cardboard forms are one acceptable means of providing this void beneath these members. Care must be exercised during concrete placement to avoid collapsing the cardboard void boxes. The cardboard carton forms should not be allowed to become wet or crushed prior to concrete placement. Permanent earth retainer forms should be used. The exterior portions of the grade beams along the perimeter of the buildings should be carefully backfilled with on—site clayey soils unless specified otherwise below. The backfill soils should be placed at a moisture content between +1% and +4% above optimum ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 10 moisture content. The fill should be compacted to a minimum of 95 percent of maximum dry density as determined in accordance with ASTM D-698 (Standard Proctor). 5.6 STRUCTURALLY SUPPORTED FLOOR SLAB Deep over -excavation would be required adjacent to the existing structure in order to reduce the potential soil swell movements to acceptable levels. Since deep over -excavation cannot be performed adjacent to the existing structure unless an elaborate system of shoring and/or underpinning is used to protect the existing structure, we recommend that a structurally supported floor slab over a minimum 12 inch void space be used. Due to the potential for excessive slab movements, one method of minimizing the effects of soil movements in areas sensitive to movement would be the use of structurally supported floor slab suspended above the underlying soils by a crawl space or a minimum twelve (12) inch void space maintained with permanent earth retainer forms. The void space created between the bottom of the floor slab and the subgrade will serve to reduce distress resulting from swell pressures generated by the clays. Any crawl space should be ventilated and drained. A suitable vapor barrier should be used below all floor slabs. Structural cardboard forms could be used to provide the required voids beneath the floor slab. If carton forms are used, care should be taken to assure that the void boxes are not allowed to become wet or crushed prior to or during concrete placement and finishing operations. Masonite placed on the top of the carton forms should be used to reduce the risk of crushing of the carton forms during concrete placement and finishing operations. As a quality control measure during construction, "actual' concrete quantities placed should be checked against "anticipated" quantities. Significant concrete 'overage" would be an early indication of a collapsed void. Note 1: A crawl space would be preferred to allow utility lines to be hung to the floor system and to allow access for future maintenance. Otherwise soil swell movements beneath utility lines would likely cause leaks and crush the pipe at connections to floor fixtures unless appropriate details are used to prevent upward movement (such as Super Void systems). All utility penetrations through grade beams and floor slabs should be sleeved appropriately to accommodate differential soil swell movement. Note 2: Large differential upward movements should be anticipated where sub -floor piping transitions to highly expansive soil at the building perimeter. Flexible connections should be used at the building perimeter to accommodate large differential movements. See Section 5.2 of this report. ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 11 Note 3: Concrete cut-off collars or clay plugs should be used for below grade piping adjacent to the building perimeter to minimize water seepage into the crawl space via utility trenches. Note 4: We recommend that a minimum 15 foot wide, 4 to 6 inch thick seal slab be placed adjacent to the existing structure within the void spaces of the addition. The required 12 inch void space should be accomplished as measured from the top of the seal slab. The seal slab will help minimize long-term drying and shrinkage of the supporting soils below the slab -on -grade sections of the existing structure. This should therefore minimize settlements of the existing shallow foundation system and floor slabs caused by long term evaporation and drying of soil within the void spaces and the adjacent slab -on -grade sections. 5.7 FLAT WORK AND PIPING CONSIDERATIONS Provisions should be made for post -construction differential upward movement of adjacent flat work and piping. Site grading plans should include provisions for the effects of soil swell movements on access and entry slabs, adjacent sidewalks and all pavements. See Section 5.2 of this report. Utility line details and fixtures should consider the potential for differential movement beneath any piping. To prevent potential tripping hazards, access and entry slabs should be elevated above the adjacent sidewalks and pavement slabs (where possible). We recommend that all access and entry slabs also be structurally supported on drilled shafts and suspended above the active clays by a minimum 12 inch drained void space. To prevent potential tripping hazards, these access and entry slabs should be elevated above adjacent sidewalks and pavement slabs and provided with transition slabs over a 12 inch void space that are hinged at grade beam connections and provided with toe beams at connections to adjacent flatwork. A schematic detail of a transition slab is provided below. Adequately Sloped Away from Building Hinged Connection to Accomodate Differential Slab -on -Grade Sidewalk Upward Soil Swell Movements / Transition Slab / Structural Supported Entry Ground Supported Toe Beam Pier Note: Transition slabs should have adequele length and should be sloped adequately to accommodate the soil swell indicated in the report. This Is required so that a positive slope away from the building is maintained after soil swelling occurs. ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 12 All void spaces should be drained. We recommend that Alliance Geotechnical Group be retained to review the project drawings and specifications to ensure compliance with the geotechnical report. 6.0 EARTHWORK GUIDELINES 6.1 SITE GRADING AND DRAINAGE All grading should provide positive drainage away from the proposed structure and should prevent water from collecting or discharging near the foundations. Water must not be permitted to pond adjacent to the structures and pavements during or after construction. Otherwise, differential soil swell movements, and resulting differential foundation movements would occur. Leave outs for drilled shafts or around the perimeter of the structures should not be allowed to collect and hold water. These leave outs should be pumped out as needed. Surface drainage gradients should be designed to divert surface water away from the buildings and edges of pavements. Surface drainage gradients of sidewalks, pavements, and landscaping, within 30 feet of the buildings should be constructed with maximum slopes allowed by local codes. Provisions should be made for post -construction differential upward movement of adjacent flat work and all pavements. Site grading plans should include provisions for the effects of soil swell movements on access and entry slabs, adjacent sidewalks, and all pavements. See Section 5.2 of this report. The roofs should be provided with gutters and downspouts to prevent the discharge of rainwater directly onto the ground adjacent to the building foundations. Downspouts should discharge directly onto well -drained areas or drainage swales, if possible. Roof downspouts and surface drain outlets should discharge into erosion—resistant areas. Water permitted to pond in planters, open areas, or areas with unsealed joints next to the structures can result in excessive flatwork or pavement movements as indicated in this report. Exterior sidewalks and pavements will be subject to post construction movement as indicated in this report. These potential movements should be considered during preparation of the grading plan. Flat grades should be avoided. Where concrete pavement is used, joints ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 13 should also be sealed to prevent the infiltration of water. Since some post construction movement of pavement and flat work may occur, joints particularly around the building should be periodically inspected and resealed where necessary. 6.2 UTILITY TRENCH EXCAVATION Trench excavation for utilities should be sloped or braced in the interest of safety. Attention is drawn to OSHA Safety and Health Standards (29 CFR 1926/1910), Subpart P, regarding trench excavations greater than 5 feet in depth. Fill placement in trenches should be performed as specified below. 6.3 PROOFROLLING AND SUBGRADE PREPARATION Prior to placing fill, the exposed subgrade in areas to receive fill should be stripped and proofrolled. Proofrolling can generally be accomplished using a heavy (25 ton or greater total weight) pneumatic tired roller making several passes over the areas. Where soft or compressible zones are encountered, these areas should be removed to a firm subgrade. Wet or very moist surficial materials may need to be undercut and either dried or replaced with proper compaction or replaced with a material which can be properly compacted. Any resulting void areas should be backfilled to finished subgrade in 8 inch compacted lifts compacted to a minimum of 95% of maximum dry density as determined by ASTM D 698 at +1 % to +4% percentage points of its optimum moisture content. 6.4 ON-SITE CLAY FILL PLACEMENT IN PAVEMENT AND LANDSCAPING AREAS The on—site surficial clays may be used for general grading and filling. The fill materials should be free of surficial vegetation or debris. Clay materials should be spread in loose lifts, less than 8 inches thick and uniformly compacted to a minimum of 95 percent of the maximum density as determined by ASTM D 698 (Standard Proctor) between +1 % and +4% above its optimum moisture content. The upper 8 inches within pavement areas should be compacted at -1% to +3% of optimum moisture content to a minimum of 98% Standard Proctor Density (ASTM D-698). 7.0 FIELD SUPERVISION Many problems can be avoided or solved in the field if proper inspection and testing services are provided. It is recommended that all pier excavations, footing excavations, proofrolling, site and subgrade preparation, subgrade stabilization, pavement construction, and concrete placements be monitored by a qualified engineering technician. Density tests ALLIANCE GEOTECHNICAL GROUP E17-0311 PAGE 14 should be performed to verify compaction and moisture content of any earthwork. Inspection should be performed prior to and during concrete placement operations. Alliance Geotechnical Group employs a group of experienced, well-trained technicians for inspection and construction materials testing who would be pleased to assist you on this project. 8.0 LIMITATIONS The professional services, which have been performed, the findings obtained, and the recommendations prepared were accomplished in accordance with currently accepted geotechnical engineering principles and practices. The possibility always exists that the subsurface conditions at the site may vary somewhat from those encountered in the test borings. The number and spacing of test borings were chosen in such a manner as to decrease the possibility of undiscovered abnormalities, while considering the nature of loading, size, and cost of the project. If there are any unusual conditions differing significantly from those described herein, Alliance Geotechnical Group, Inc. should be notified to review the effects on the performance of the recommended foundation system. The recommendations given in this report were prepared exclusively for the use of the client, their client and their consultants. The information supplied herein is applicable only for the design of the previously described development to be constructed at locations indicated at this site and should not be used for any other structures, locations, or for any other purpose. We will retain the samples acquired for this project for a period of 30 days subsequent to the submittal date printed on the report. After this period, the samples will be discarded unless otherwise notified by the owner in writing.
