Key to Symbols and Descriptions Botanic Gardens Greenhouse Facility,Fort Worth, Texas January 30, 2004 GEOTECHNICAL EXPLORATION FORT WORTH BOTANIC GARDENS GREENHOUSE FACILITY FORT WORTH, TEXAS' 1.0 PROJECT INFORMATION The project consists of a-headhouse,four greenhouses,an office/breakroom'and a shop/garage for the Botanic Gardens Greenhouse Facility to be located in the current Lockheed-Martin parking lot near the intersection of Interstate 30 and Montgomery Street in Fort Worth,Texas(Figure 1). The headhouse will be approximately 3,692 square feet(SF).in plan area,the four green houses will be approximately 35,624 SF,the shop/garage will be approximately 13,725 SF,and the office/breakroom building will be approximately 4;000 SF in plan area. We assume that the buildings will have relatively light loads.'We.assume that the finish floor of the.. buildings will be within 2 feet of the current site,grades. -2.0 SCOPE OF SERVICES Our services for -this .project were performed in- general conformance with our Proposal No.. PROP03FTWO.0395 dated 12/8/03. The purposes.of this geotechnical evaluation were to:. • Explore the subsurface conditions at the site Characterize the subsurface soil and groundwater conditions • Provide recommendations for a suitable foundation system,and • Provide comments and recommendations concerning pavement,site grading and drainage. 3.0 FIELD EXPLORATION Thirteen borings were drilled at the locations marked on the site plan sent to us.Seven borings were terminated at a depth of 25.feet, one boring was.terminated at a depth of 3 5.feet and five borings were-terminated at a ® depth of 40 feet:The approximate boring locations are shown on the enclosed Boring Location Plan(Figure 2). A truck-mounted drill rig was used-to advance the borings and to obtain samples for laboratory:evaluation. Undisturbed specimens.of the cohesive soils were obtained continuouslyto a depth of5 feet;and samples were obtained from 7 to 8 feet and from 9 to 10 feet and at 5 foot intervals thereafter using standard,seamless tube } samplers. The samples were extruded in the field, logged, sealed -and packaged to protect them from disturbance and to maintain their in-situ moisture contents-during transportation to our laboratory. Sampling depths for the soil samples are presented.on the Logs of Boring(Figures 3 through 15). Ad4CTEC'Engineering and Consulting Inc. Report No. 4902-03-3338 .Page I Botanic Gardens Greenhouse Facility,Fort Worth, Texas January 30, 2004 Foundation bearing properties of the sand encountered in-the borings was evaluated by Standard Penetration tests 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 number of blows for each 6-inch increment or the penetration fro 50 blows.The results oftlie Standard Penetration tests(blow count of last foot)are recorded at the respective testing depths on the Logs.of Boring. Limestone encountered in the borings was evaluated in the field by the Texas Department of Transportation ,.- Penetrometer(TxDOT Cone) tests. The TxDOT.Cone is driven with the resulting penetration-in inches recorded for 100 blows. The results of the TkDOT Cone tests are recorded at the respective testing depths on. the Logs of Boring(Figures 3 through 15). 4.0 LABORATORY TESTING The project geotechnical engineer examined the samples at our laboratory and revised the field classifications as necessary. Selected samples were subjected to laboratory tests under the supervision of this engineer. Moisture contents and Atterberg limit tests were performed to evaluate the potential volumetric change of the different strata. Pocket penetrometer and unconfined compression tests were performed to estimate the — compressive strength ofthe soil.To provide additional information about the swell characteristics ofthese soils (at their in-situ moisture conditions), absorption swell tests were performed on selected samples of the dark j brown clay soil. The results of these tests are provided on the Logs of Boring. i 5.0 SUBSURFACE CONDITIONS A brief description of the conditions that were encountered in the borings is presented.below.Amore detailed description of the subsurface conditions is presented on the attached Logs of.Boring. It should be noted#hat the boundaries between the various soil types are approximate and may vary. In addition,the depths shown on the Boring Logs refer to the depths fi-om the ground surface that was present at the time of the field exploration program. 5.1 Site Geology, The site is located in an area underlain by alluvium deposits underlain by the Duck Creek Formation. The alluvium deposits consist of silt,sand clay and gravel. The Duck Creek Formation consists of limestone.At A"CTEC Engineering and Consulting Inc. Report No.4902-03-3338° Page 2 Botanic Gardens Greenhouse Facility,Fort A'orth, Texas January 30, 2004 this site the existing on-site pavement materials are underlain by layers of clay followed by sand and underlain by gray limestone. 5.2 Stratigraphy '~ The stratigraphy consists of 2.25 inches to 2:75 inches of asphalt on top of base material followed by dark brown to brown clay with calcareous nodules to depths of 2 to 8.5 feet.In Boring B-9,the pavement materials were underlain by dark brown and brown clay fill to a depth of 5 feet, in turn underlain by the natural dark brown to brown clay with calcareous nodules.The dark brown and brown clay with calcareous nodules was underlain by orangish tan clay with calcareous nodules to depths of 18.5 to 28 feet.In Borings B-4,B-5 and B- 7, a layer of light gray and tan sandy clay was encountered sandwiched between two layers of orangish tan clay.In Boring B=12,light gray and tan sandy'clay was encountered between orangish tan clay and light gray sand.In Borings B-2,B-4,B-5,B-7,B-10,13-11 and B-13,the orangish.tan clay with calcareous nodules was underlain-by sand to the boring termination depth of 25 feet. In Borings B-1,B-3,B-6,B-8,B-9 and B-12,the orangish-tan clay with calcareous nodules was underlain by layer(s)of sand followed by gray limestone with shale seams to the boring termination depths.Gray limestone with shale seams was encountered at depths of 28 to 31 feet in the.borings.In Boring B-6 and B-12,a layer of tan weathered limestone was encountered above the gray limestone.In Boring B-8,a layer of tan gravelly sand was encountered sandwiched between two layers of orangish tan clay.The.orangish tan clay was underlain.by dark gray and gray weathered shale to a depth of 28 feet followed by gray limestone to the born— 'termination r depth of 35 feet d The dark brown to brown clay.with calcareous nodules exhibited liquid limits-ranging from 52 to 60 with plastic limits ranging from'23 to 26 and with plasticity indices ranging from 29 to 34.The moisture content in the dark brown to brown clay with calcareous nodules ranged from 13 to 27 percent.The absorption/swell test results in the dark brown to brown clay with calcareous nodules ranged between 2.1 and 3.1 percent. The orangish tan,clay with calcareous nodules exhibited liquid limits ranging from 30 to 46 with plastic limits ranging from 16 to 22 and with.plasticity indices ranging from 14 to 24.The moisture content in the orangish tan-clay with calcareous nodules ranged.from.9 to 23 percent.The unconfined compression test results in the orangish tan clay with-calcareouszodules ranged between 2.6 and 7.7 kips per square foot(ksf).The light gray and tan sandy clay encountered-in Borings B-4, B-5, B-7 and B-12.had unconfined compression strength AdACTEC Engineering and Consulting,Inc. Report No. c IL7 C 1 Botanic Gardens Greenho:►se Facility,Fort Worth, Texas January 30, 2004 ranging from 1.7 to 2.6(ksf).The gray limestone with shale seams exhibited TxDOT cone values ranging from 0.25 inches per 100 blows to 1.75 inches per 100 blows. 5.3 Ground Water Conditions The borings were advanced using continuous flight auger drilling equipment. Depending on the soil type,this method may result in relatively accurate short-tern ground water observations while drilling. Subsurface ground water seepage was not encountered in Borings B-2,B-4,B-10 and B-11 during drilling and at boring. completion.Ground water readings were taken after 24 hours in the borings drilled the previous day.Borings B-10 and B-11 were dry after 24 hours.The following Table 1. lists the ground water readings in-rest of the borings.

Furthermore;the presence and magnitude of groundwater will fluctuate seasonally due to variations in the amount of precipitation and infiltration of this°site and surrounding-area. The presence or absence of MACTEC Engineering and Consulting,Inc. Report No..4902-03-3338 y Page 4 Botanic Gardens Greenhouse Facility;Fort Worth, Texas January 30, 2004 groundwater should be verified prior.to construction that'would be adversely impacted by subsurface groundwater. The evaluation of the potential presence of pollution or ground water contaminants in the soil or ground water at this site was beyond the scope of this project 6.0 ANALYSIS AND RECOAMNDATIONS 6.1 Suitable Foundations. The Texas Department of Transportation's(TxDOT)empirical method of predicting Potential Vertical Rise (PVR)was utilized to develop the foundation design criteria associated With soil movements resulting from swelling. PVR values obtained using this method assume that the supporting soil is not subject to free water sources and as*a result,never becomes fully saturated nor reaches its full swell potential. PVR values using this method are typically much lower than values obtained from:laboratory swell tests. When this-design method is used it is imperative that all potential free water sources are eliminated in.order to prevent excessive upward movement caused by soil swelling. It is also imperative that measures be taken during design and _ construction to reduce the risk of free water sources near the foundation. The clay that was encountered at this site has moderate to high shrink/swell potential. A Potential Vertical Rise (PVR) calculation was performed using the TxDOT,Method 124-E, assuming a dry,soil•moisture condition.Based upon these calculations,it is estimated that the PVR of a slab-on-grade is on the order of 1.0 to 2.0 inches. i . Considerably more upward movement than the potential soil movement value estimated above will occur in areas where water is allowed to pond near or beneath the structure for extended periods due to poor drainage, T— leaking.utility lines,percolation in recessed landscape areas, or leaking sprinkler lines. The soil conditions J encountered at the site may also differ from those encountered at the boring locations;which could influence ' . the estimated soil 'movement Recommendations for.two alternative foundation types are presented.These alternative foundation types.are: ' Drilled Shafts with Slab on Modified Subgrade Stiffened Slab-On-Grade Foundation- AM OTEC oundation-MACTEC Engineering and Consulting Inc. Report No.:4902-03-3338 Page 5 Botanic Gardens Greenhouse Facility,Fort Worth, Texas January 30, 2004 Drilled shafts with slab on modified subgrade should be used if it is required to limit potential.building movements to on the order of 0.5 inch,and to limit potential floor slab movements to on the order of 1.0 inch. The.grade beams are supported by drilled shafts. The grade beams are separated from the active clays. The floor is supported on a modified subgrade to reduce subgrade movements. There is a risk that subgrade movement greater than 1.0 inch could occur because of leaking waterlines or other sources of water. A stiffened slab foundation is recommended if foundation differential movements to the order of 2-inches can be tolerated by the building. This foundation system consists of perimeter and interior grade beams that create a stiffened slab to limit differential movements in the building superstructure. However,.since this foundation . system is fully supported by expansive soils,there is an inherent risk of unacceptable.foundation movements occurring. Should a leak develop in a utility line under the building,foundation movements could.result in serious damage to the structure. Because of the inherent risk of leaking utility lines at a•greenhouse facility, for the greenhouses-and the headhouse, drilled shafts with slab on modified subgrade could be used, and for the shop/garage and office/break room building either of the foundation systems could be used. Recommendations for.the two .foundation systems are presented in-the following report sections. 6.2 Drilled Shaft Foundation System 6.2.1 Allowable Bearing Capacity J The drilled shafts should penetrate at least 3 feet into the gray limestone with shale seams to develop the _�. recommended end bearing value.We recommend that a maximum allowable bearing pressure of 40,000 psf be used for the drilled shafts.Drilled shafts should have a minimum diameter of 18 inches to allow access-for observation. An allowable skin friction of 4,500 psf(compression)and an allowable skin friction of 3,500 psf(tension)are recommended in the gray limestone. The recommended allowable end bearing value contains a factor of safety of 3. The recommended skin friction values contain.a factor of safety 42. Settlements ofthe drilled shafts are estimated to be less than 0.5 inch.•The settlement is expected to occur as the shaft is loaded. MACTE.0 Engineering and Consulting,Inc. ' Report No. 4902-03-3338 Page 6 �. - Botanic Gardens Greenhouse Facility,Fort Worth, Texas January 30, 2004 - 6.2.2 Drilled Shaft Supported Grade Beams The grade beams should be supported by the drilled shafts. A minimum void space of 6 inches should be provided between the bottom of these members and the subgrade.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. As a quality control measure during construction, "actual" concrete quantities placed should be checked against"anticipated"quantities. Significant concrete"average"would be an early indication of a collapsed void. The exterior portions of the grade beams along the perimeter of the building should be carefully backfilled with on—site clayey soils unless specified otherwise below. The back ill soils should be placed at moisture content between optimum to+3 percentage.pofi is wet of optimum, The fill should be compacted to 95 percent of maximum dry density as determined in accordance with ASTMD-698(Standard Proctor). 6.2.3 Group Effects For groups of drilled shafts,where the spacing between shafts will be less than 2.5-shaft diameters (2.5D) center to center,a reduction factor should be applied to the allowable skin friction for the determination of required shaft penetrations. For shafts touching,a reduction factor of 50 percent should be used. For a spacing of 2.5D, where D is the.diameter of the largest adjacent shaft, no reduction is necessary. A straight-line interpolated reduction.shoul'd'be used between drilled shafts touching and a spacing of 2.51). . . �- 6.2.4 Drilled Shaft Soil Induced Uplift Loads I Drilled shafts will be'subject to uplift loads as•a result of swelling within the overlying clays.The drilled shafts should have sufficient continuous vertical reinforcing steel extending to the base of the shafts to resist the a 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 i uniform uplift pressure of 1,000 pounds-per square foot acting on the shaft perimeter for a depth of 10 feet MACTEC Engineering and Consulting,Inc Report No. 4.9 Z- OUNL M. Botanic Gardens Greenhouse Facility,Fort Worth, Texas January 30, 2004 6.2.5 Drilled Shaft Construction Considerations Ground water seepage was encountered in all the deep borings during drilling and at completion.Water was observed in all the deep borings after 24 hours and all the deep borings caved in after 24 hours except Boring B-1. Casing will be needed at this site during drilled shaft construction. Concrete used for the shafts should have a slump of 6 inches plus or minus 1 inch and placed using a tremie to limit the free fall of the concrete to five feet 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. The top of the drilled shafts should be formed to prevent an enlarged top that could'be lifted by swelling clays. We.recommend that MACTEC be retained to observe and document the drilled shaft construction. The engineer,or his representative,should document the shaft diameter,depth,cleanliness,plumbness ofthe 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 shaft excavation should be observed to verify the bottom of the hole is dry and thoroughly cleaned of cuttings.No build-up of cuttings J what so ever should be allowed. Recommendations for underreamed shafts are not provided in this report as a layer of gravelly sand was .encountered from a depth of 13 feet to 17.5 feet in Boring B-8. 6.3 Slab-On-Grade Recommendations As discussed previously,soils are estimated to have potential vertical movements on the order of 10 to 2.0-inches. Site preparation work will be required in order to lower the potential soil movements to'about 1' inch. Recommendations for reducing the soil PVR are presented in the following section. A polyethylene moisture barrier is recommended below the slab-on-grade floor slabs where floor coverings or painted floor surfaces will be applied with products which are sensitive.tomoisture or if products stored.on the building floors are sensitive to moisture. Procedures for installation of vapor barriers are recomimended'in ACI . 302 Section 2.4:1. Mf!CTEC Engineering and Consulting,Inc. Aeport No.4902-03-3338 Page 8 Botanic Gardens Greenhouse Facility,Fort Worth, Texas .Janua7y 30, 2004 "- 63.1 Subgrad6 Preparation For Slab-On-Grade Floor The following subgrade preparation procedures will be required to reduce the soil PVR to about I inch. I. Excavate to depth of 3 feet below existing grade. Excavation should extend to five feet outside building lines or beneath adjacent sidewalks and entry areas,whichever is greater. 2. Scary,rework,and recompact the upper 8 inches of the exposed subgrade soil. The scarified soil should be recompacted-to 95 percent of the maximum density as determined by ASTM D. 698 at moisture content between+1 to+4 percentage points above optimum. 3. Fill to final pad,grade using non-expansive select fill having a PI between 5 to 15. Compact at optimum to+3 percentage points above optimum to a minimum of•95 percent maximum density as determined by.ASTM D 698. Select fill limits should extend to building lines, entries and adjacent sidewalks. 4. The moisture condition of the completed pad must be maintained until all slabs are in place:This will be particularly important along the building perimeter where clay soils will be exposed in grade beam -excavations. All pavement and landscaped grades within 10 feet ofthe building should be sloped along maximum grades allowed by local code to accommodate differential soil swell after construction and thereby rninimiz;ng ponding conditions near the building caused by post-construction soil swelling. 6.4 Stiffened Slab=On-Grade Either post-tensioned or conventionally reinforced mono]ithic stiffened slabs can•be considered for the proposed building and should be designed by a structural engineer to withstand the estimated vertical soil movements. A polyethylene moisture-barrier is recommended below the slab-on-grade floor slabs where floor coverings or - painted floor surfaces will be applied with products which are sensitive to moisture or if products stored on the building floors are sensitive to moisture. Procedures for installation of vapor barriers are recommended in ACI 302 Section 2.4.1. 6.4.1 Allowable Bearing Capacity Grade beams founded in the naturally occurring soil or in properly compacted fill soil may be designed using an'allowable soil bearing pressure of 2,000 pounds-per square-foot The grade beams are recommended to �- -have a minimum width of 10 inches to provide a margin of safety against local or punching shear failure of the bearing soil MWTEC Engineering and Consulting,Inc. Report No. 4902-03-3338 -.. Page 9 Botanic Gardens Greenhouse Facility,Fort Worlh Texas January 30, 2004 The exterior walls should contain vertical crack control joints placed at 10 to 12 foot on-center forthe height of all walls to control cracking associated with differential foundation movements. It is also recommended that pavement(or a minimum 5-foot wide sidewalk or seal slab)extend to the edges of the building to protect the -- active supporting soil from excessive moisture losses(and resulting settlements)after construction. Trees and deep-rooted shrubs should be located no closer to the structure than one-half their ultimate mature height to reduce the potential for foundation settlement caused by moisture absorption of the root systems. It is common to experience some distress to structures due to ground movements. This includes cracks in the -. brick and cracks'in ground supported slabs. Cracks in the exterior brick-walls are less noticeable with the use of closely spaced vertical joints along the walls. It is recommended that a MACTEC geotechnical engineer or a qualified engineering technician observe the footing excavations prior to placing concrete. The foundation bearing-grade should be level-or suitably benched.It should also be free of loose soil,ponded water and debris.p=ior'to the inspection. 6.4.2 Post-Tensioning Design Parameters Design criteria for a slab designed in accordance with the Post-Tensioning Institute's (PTT) slab-on-grade design method have been developed. The edge moisture variation distances(e.)for-center lift and edge lift conditions were derived based on a Thornihwaite Index ranging.from 0 to-1 Hor the project site. The edge moisture variation distances are based upon the PTT Manual criteria and are provided in Table 2. TABLE Z. EDGE MOISTURE VARIATION DISTANCES (EM) 1 CENTER LIFT CONDITION em=5.5 feet +` l • EDGE LIFT.CONDITION em=4.5 feet The Post-Tensioning Institute(PTT)method incorporated numerous design assumptions associated with the derivation of required variables needed to determine the soil design criteria. The PTT method of predicting differential soil movement is applicable only when site moisture conditions are controlled by the climate alone on a well-graded site(i.e.no improper drainage,water leaks or free water sources). Under these conditions; moisture increases within the'supporting soil and the resulting differential foundation movements are much IkWTEC Engineering and Consulting Inc. Report No. 4902-03-3338 Page 10 Botanic Gardens Greenhouse Facrl,, Fort Worth, Texas January 30, 2004 lower than.differential movements that can occur due to post-construction movements due to localized saturation caused by free water sources near or beneath the structures.

It should be recognized that a post-tensioned or conventionally reinforced slab-on-grade foundationsystem placed at this site will be subjected to some differential movements as indicated above. These movements can cause cracking of interior sheet rock walls and exterior brick walls. Occasionally, differential movements can cause planarmovement of window frames and door frames requiring adjustments to the.doors and windows. �- 7.0 PAVEMENT RECOMMENDATIONS J We assume that a typical automobile or pickup truck is representative of-essentially all of the traffic on the proposed parking area pavements. We further assume that only occasional heavy to medium truck traffic from primarily waste disposal trucks and delivery trucks will be present on the parking area-pavements. The T following recommendations are based upon these assumed conditions. 7.1 Subgrade Preparation SurficW.clays present at.this site are active, and are subject to losses in shear strength with increases m moisture content which normally occur beneath area paving. They typically react with hydrated lime,which serves to improve their support value at higher moisture levels and provide a firm,•uniform'subgrade beneath M4 MC Engineering and Consulting Inc. Report No 4902-03-3338, Page I I Botanic Gardens Greenhouse Facility,Fort Worth, Texas January 30, 2004 the paving.We recommend that sulfate tests be conducted to determine the amount of sulfates present in the subgrade before using lime stabilization.If sulfates are present in the subgrade they react adversely with lime to cause more damage to the pavement instead of stabilizing it. We typically recommend stabilization of subgr ides beneath all flexible type pavements. Stabilization beneath .� concrete pavement subject only to automobile traffic is optional. Based on the Atterberg limits tests,6 percent hydrated lime by dry weight(27 pounds.per square yard per 6-inch depth)is recommended to stabilize the existing clay subgrade soils. The lune should be thoroughly mixed and blended with the top 6 inches of the subgrade(TxDOT Item 260)and the mixture compacted to a minimum of 95 percent of maximum dry density as determined in accordance with ASTM D 698,within3 percentage points of the soil's optimum moisture content. Project specifications should allow a curing period between initial and final mixing of the lime/soil mixture. After initial mixing,the lime treated subgrade should be lightly rolled and maintained at or within 5 percentage points above the soil's optimum moisture content until final mixing and compaction..We recommend a 3-day curing period for these soils. The following gradation requirements are recommended-for the stabilized —� materials prior to final compaction: Percent Minimum Passing 13/4" Sieve 100 Minimum Passing No.4 Sieve 60 J All nonslaking aggregates retained on the No.4 sieve should be removed prior to testing. We recommend that stabilization extend 1 to 2 feet beyond exposed pavement edges, if possible,in order to ' reduce the effects of shrinkage during extended dry periods. The prepared subgrade should be protected and J moist cured or sealed with a bituminous material for a minimum of 7 days or.until the pavement materials are placed. Pavement areas should be graded at all times to preventpondingand infiltration of excessive moisture on or adjacent to the pavement areas. j Due to the presence of expansive clay soils, some pavement movements should be anticipated,even if our recommendations are strictly followed. Irispection'during construction is particularly important to insure proper construction procedures are followed. MACTEC Engineering apd Consulting,Inc. Report No. 4902-03-3338 Page 12 Botanic Gardens Greenhouse Facility, Fort Worth, Texas January 30, 2004 7.2 Recompacted Pavement Subgrade If subgrade stabilization is not performed,the upper six(6)inches of subgrade soil should be compacted at optimum to+3 percentage points of optimum moisture.-The subgmde should be compacted to a minimum of 95%Standard Proctor density(ASTM.D 698). Only on-site soil(comparable to the underlying subgrade soil) should be used for fine grading the pavement areas.After fine grading, the subgrade should again be watered if needed and re-compacted in order to re-achieve the moisture and density levels discussed above and provide a tight non-yielding subgrade. Sand should not be allowed for use in fine grading.the pavement.The subgrade moisture content anddensity must be maintained until paving is completed. The subgrade should be watered just prior to paving to assure concrete placement over a moist subgrade. 7.3 Pavement Sections Recommendations for pavement are provided in the following Tables 4 and 5.The pavement sections provided -in Table 4 are recommended for areas that will be subject to relatively light traffic loads,such as the parking stalls for automobiles. The pavement sections provided in Table 5 are recommended for areas that will be* subject to moderate traffic loads, such as,drives and areas subject to occasional truck traffic. The type and — volume of traffic were not provided to us. We have assumed-traffic loading of 25,000 ESAL's;(Equivalent Single Axle Applications)for the light duty pavement and a loading of 100,000 ESAL's for the medium duty pavement. These are estimates and should be refined when better data is available. J .Asphaltic concrete pavement should. be'placed in accordance with Item 340 of TxDOT's Standard Specification, 1993 edition:The surface'course asphaltic concrete should comply with Type D of Item 340 and the Base course asphaltic concrete should comply with Type B of TxDOT Item 340. Crushed limestone base material should conform to Item 247,Type A,Grade 2 or better of TxDOTs Standard Specification, 1993 edition.The base layer-should be constructed in lifts not exceeding 6 inches compacted thickness and to a minimum density of 95 percent of maximum as determined by ASTM D 1557. The concrete should have a minimum 28-day compressive strength of 3,5 0.0 psi. Concretequality will be .� important in order to produce the desired flexural strength and-long-term durability, Assuming a nominal maximum aggregate size of 1 to 1-3/8 inches,we recommend that the concrete have entrained air of 5 percent (±1%)with a maximum water cement ratio of 0.5.0.

All joints including saw joints should also beproperly cleaned and sealed as-soon as-possible to avoid infiltration ofwater,small gravel, etc. We have found that joint spacing on 12 to 15 foot centers have generally-performed satisfactorily. It is our recommendation that the concrete pavement be reinforced with No.3 bars on approximately 18-inch centers in each direction or equivalent reinforcing steel. 7.4 Special Pavement Considerations 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 surflicial materials may need to be undercut and either dried and replaced with proper compaction or replaced with a material that can be properly compacted. Any resulting void areas should be backfilled to finished.subgrade in 6 inch compacted lifts compacted to 95 percent of maximum dry density as determined by ASTM D 698. Achieving the required field density is dependentupon the adequate pulverization of the clay fill materials,the magnitude of compaction energy and the maintenance of field moisture near optimum. ' All joints and pavements should be inspected at regular intervals to ensure proper performance and to'prevent - crack propagation: -: The soils at the site are active and differential heave within'the parking area could potentially occur. The service life of paving may be reduced due to.water infiltration into subgrade soils through.heave induced cracks in the paving section. This will result in-softening and loss of strength of the subgrade soils. A regular maintenance program to seal paving cracks and joints will help prolong the service life of paving. The life of the pavement can be increased with proper drainage. Areas should be graded to prevent ponding adjacent to curbs or pavement-edges. Curb areas should be backfilled as soon as practical.after the concrete= has set,preferably with the on-site clay soils. Backfill materials, which could hold water behind the curb, should not.be permitted. Flat pavement grades should be avoided. . MACTEC Engineering and Consulting,Inc. Report No. 490243-3338 - Page 15 Botanic Gardens Greenhouse Facility,Fort Worth, Texas January 30, 2004 8.0 SITE GRADING AND UTILITY EXCAVATIONS 8.1 Site Grading and Landscaping All grading should provide positive drainage away from the structure and should prevent water from collecting or discharging near the foundations. Water must not be permitted to pond adjacent to the structure during or after construction. Surface drainage gradients should be designed to divert surface water away from the building and edges of pavements and towards suitable collection and discharge facilities.Surface drainage gradients within 10 feet of the buildings should be constructed with a minimum slope of 1 percent. _. The roofs should be provided with gutters and downspouts to p;event the discharge of rainwater directly onto ' the ground adjacent to the building foundations. Downspouts should discharge directly into storm drains or drainage swales,if possible. Water permitted to pond in areas with unsealed joints next to the structure can result in on-grads slab or pavement movements, which exceed those indicated in this.report. It is emphasized that predictions of J moisture related differential movements indicated in this report are based on empirical calculations and mm- previous experience. In some cases movements can exceed those predicted,particularly when unusual sources of water become available to the underlying clay. t Exterior sidewalks and pavements will be subject to some post construction movement. Flat grades should be j avoided. Where concrete pavement is used,joints should be sealed to prevent the infiltration of water. Since J • Some post construction movement of pavement and flatwork may occur,joints particularly around the Building should be periodically inspected and resealed where necessary. 8.2 Utility Trench Excavations 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),SubpartP,regarding trench excavations greaterthan 5 feet in depth. AMCTEC Engineering and Consulting,Inc. Report No. 4902-03-3338 Page 16 Botanic Gardens Greenhouse Facility,Fort Worth, Texas January 30, 2004 8.3 Field Supervision and Density Testing Field density and moisture content determinations should be made on each lift of fill with a minimum of 1 test per lift per 3,000 to 5,000 sf in the building pad area and 1 test per lift per 100-to 150 linear feet of utility trench backfill. Supervision by the field technician and the project engineer is required.Some adjustments in the test frequencies may,be required based upon the general fill types and soil conditions at the time of fill placement Many problems can be.avoided or solved in the field if proper inspection and testing services are provided. It is recommended that all site and subgrade preparation and proofrolling be monitored by a qualified engineering technician.Density tests should be performed to'verify compaction and moisture content of any earthwork. Inspection shouldbe performed prior to and during concrete.placement operations. MACTEC employs a group of experienced,well-trained technicians for inspection and construction materials testing who would be pleased to assist you on this project 9.0 LI TATIONS 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 J� practices. The possibility always exists that the subsurface conditions at the site may vary somewhat from those encountered in the borings. If there are any unusual-conditions differing significantly from those described herein, we 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 City of Fort Worth and their ( designconsultants. The information supplied herein is applicable only for the design of.the previously PP PP � Y gn Pr t3' described additions to be constructed at locations indicated at this site and should not be used for any'other structures, locations, or for any other purpose.
