Flarida Geological Sttrvey Sinkl�ole Database The Florida Geological Survey maintains a databas of lcnown subsidence events which are reported as sinklaoie occurrences. The database zs cotnpiled by count and infarznation includes Township, Range and Section, physical street address or directions to a sinkhole si e,clasest city,and date of occurrence. The sinkhole database is not a coinplete listing of all sinlcliales within tlae ounty. It is only a listing of reported sinkhale events known to tize deparhnent and campiled from the fonner�l rida Sinklzole Research Institute. Many of the reports in the database liave nat been verified by a professional; onsequently,many of tlie reparted subsidence events are not actually related to sinkhale activity.

The process for explpring sinkhole clailns is rnulti-phased including a site vi it and an interview with the l�azneawner,geophysical testing, direct saxnpling, and laUoratory testing. T11e process for exploring sinlciiole claims is mul '-�l�ased. Tl�e field work coinmences wlien the geotechnical engineer contacts the hoineowner and arranges a ite meeting to gather background infarmatian and review the cunent conditions of tlze structure and property. he candition of the structure and site rnay provide ciues to t11e engineer that will help him design the exploration program. During the reconnaissance of the site,the engineer can begin to consider other possible cal�ses of dan age in addition ta sinkholes. For exalnple,if tlle ha�ne resides on a steep slope or the homeowner has reported r peated problems with sewer l�lockage,then the engineex may madify the scope to il�ciude slope stability analys's or utility leak detectian analysis in additian to the sinlcl�ole investigation techniques. It is important that the ause of damage be esCablished if sinkholes are eliininated as a cause. Following the site reconnaissance,the geophysic 1 phase of worlc is cominenced. The geopliysical exploration generally involves the use of sarne non-invasive xploration znetlaods,sucll as ground penetrating radar(GPR} � Guilarte Residence-Claim No.354110 HCE Report No. 100091.1 Page No.4 or electrical resistivity iinaging (ERI). The engin er will utilize his knowledge of local subsurface conditions, site conditions,and information obtained through ublicly available records to select the proper geophysical tool for the site. The geophysical tools provide large a ea coverage of the site and help the engineer select locations for fiiture invasive,direct sainpling. The geophys cal tools are analogous to ultra-sound,x-ray or MRI inedical procedures that doctors use. The geophysical tools rovide a subsurface iinage that can be interpreted by a trained engineer or geologist. Frequently,the geophysic 1 testing will identify soine unusual condition relative to the overall background condition. This unusual coiid'tion relative to the background conditions is usually referred to as a feature or an anoinaly. Feattires may be ca sed by sinkholes,buried tree stumps,buried utilities,fonner stream beds,previous excavation activities and/or numerous other sources. The geophysical equipinent is used as a screening tool to aid the selection of borin locations to target features as well as to evaluate normal background conditions. Using the geophysical exploration results, the en ineer selects locations for invasive testing. Invasive testing usually involves Standard Penetration Test(SPT) orings or Cone Penetration Test(CPT)soundings. The SPT and CPT techniques require boring into the groun to collect and obtain relative strength data of soil samples or pushing a probe into the ground to ineasure physi al soil properties,respectively. If necessary,laboratory tests are perfonned to further define the physical prop rties of representative soil sainples. In addition to the SPT or CPT borings,shallow au er borings are commonly performed. The auger borings may be placed close to the structure to gather addition 1 data about the site preparation and soils present at the edge of the structure,or at other locations such as those closer to the foundation than can be accessed with the SPT or CPT rigs. As a matter of routine,a test pit is pe nned adjacent to one exterior wall of the strucriire to expose the foundation system. The depth, width and liysical condition of the foundation are also recorded for evaluation. The data froin the invasive testing is compared ith the geophysical suivey data and the laboratory tests. The engineer considers the collected soil infonnation the stnicture condition, dainage patterns, and historical and publicly available data and possibly additional av ilable infonnation to develop an opinion about the sinlcholes as a cause of damage. If the evahiation results in negative conchision regarding sinkhole activity as a cause of structure damage,then alternate likely causes of amage are presented. Coimnonly, structure damage is caused by the presence of poor soil conditions such as eat, debris, or unsuitable fill below the structure. Nuinerous possibilities exist. If the evaluation results in a ositive conchision regarding sinkhole activity as a cause of dainage,then a reinedial repair plan or other cou se of action is provided in the report conclusions. Field Methods The procedures used by HCE for field testing are in general accordance with industry standards of care, established geotechiiical engineering practices and Ainerican Society for Testing and Materials (ASTM) 'standards. The exploration consisted of perfoi ing a Ground Penetrating Radar (GPR) survey around the perimeter of the house and within the interior of he residence. After reviewing the results of the GPR suivey, four(4) Standard Penetration Test(SPT)borings were perfonned to depths of 58 feet 9 inches, 59 feet, 73 feet 10 inches, and 79 feet 5 inches below the exis ing ground surface. In addition, a Floor Level Survey was performed on the interior, and two (2) shallow a iger borings, and two (2) test pits were performed around the periineter of the house. The borings and test pi s were perfonned at the approxiinate locations shown on the attached Location Plan. Descriptions of each fi ld test method and the results of the tests are presented in the following sections. Guilarte Residence-Claim No.354110 HCE Report No. 100091.1 Page No. 5 Ground Penetrating Radar A Ground Penetrating Radar(GPR)survey was con ucted at the site in areas of the yard surrounding the house and within the interior of the residence. GPR uses transmitter/antenna pulled along the ground surface that transinits radio waves into the ground and records si nals reflected back froin soil layers. The reflected signals are recorded in digital format and represent virtual c oss-sections of the subsurface soils. The recorded signals are examined for lateral continuity of the soil stra a. The limits of discontinuities or dramatic changes in continuity are identified on a scaled site plan and d lineated as features of interest. The data interpretations, relative to the possible presence of sinlchole activity are performed by an experienced,professional geologist. The results of the survey and the interpretations of t e data are presented in the final GPR survey report. The coinplete GPR survey report is attached in A ei�dix C of this report. Standard Penetration Test(SPT)Borings The four Standard Penetration Test(SPT)borings we performed in general compliance with ASTM's procedure for standard field penetration tests,D-1586. The bor ngs extended to depths of 58 feet 9 inches,59 feet,73 feet 10 inches, and 79 feet 5 inches. The SPT borings were advanced by means of an all-t rrain vehicle(ATV)-inounted drill rig.The ATV-mounted rig was used to limit damage to the landscaping and o allow easier access to boring locations. The drilling was performed employing wash rotary drilling technique and bentonite drilling fluid to stabilize the boreholes. At periodic intervals,the soil was tested and sampled b ineans of the Standard Penetration Test. The borings were performed in general compliance ith ASTM's procedure for standard field penetration tests, D-1586. After drilling to the sainpling depth and cl aning the borehole,the standard 2-inch outside diameter, split-barrel sampler was seated by driving it 6 inch s into the soils at the bottom of the borehole. Then the sampler was driven an additional 12 inches by a 14 -pound harruner falling 30 inches. The number of blows required to produce the 12 inches of penetration is -ecorded as the penetration resistance N. This N-value is plotted on the left side of the Boring Logs which are attached in Appendi,r D. Fi�zn•es 2 ar�d 3. The SPTs were perfonned continuously to 10 feet a d at 5-foot intervals thereafter to the terminations depths. The upper 4 feet of the SPT borings are generally ad anced by hand auger to prevent dainage to possible buried utilities. The soil sainples were obtained at the deptl s where the SPTs were perforined. The soil sainples were then classified in the field,placed in sealed containe s, and retuined to our laUoratory for further evaluation Uy our project engineer. Auger Borings The auger borings were performed by manually turni g a 3-inch diameter,6-inch long sam�ler into the soil until it was full. The sampler was then retrieved and the s ils in the sampler were visually classified. The procedure was repeated until the desired tennination depth wa achieved. Sainples of representative strata were obtained for fiu-ther visual evaluation and classification in o r laboratory. The Auger Boring Records are attached in Apper7dix D. FiPan•e S of this report. Test Pits i Two test pits were excavated on the rear side near the right rear corner of the residence,and on the front side near the fi-ont right corner of the residence,and the result are presented in the following section of this report. The test pits were hand excavated next to and beneatl� t e exterior walls to obseive and record the type, size, and condition of the foundation. \ Guilarte Residence-Claim No.354110 HCE Report No. 100091.1 Page No. 6 Soil Sample Handling and Classification The soil samples obtained during the SPT borin s were placed in sealed containers to retain moisture and then returned to our laboratory. The samples were th n reviewed by our project engineer to confinn classifications, visually estimate the relative percentages of tl e soil's constituents (sand, clay, etc.), and identify pertinent structural feahires. The stratification lines s own on the boring records represent our interpretation of approximate boundaries between soil types. Th transition between strata may be gradual. Our classifications are based on a visual estimation of the soil prope ies and our engineering experience with the soils found in this geologic area. Floor Level Survey A floor level survey was conducted using a water evel manoineter. The manoineter used a tripod supported water reservoir connected to water filled clear tubing. The tubing tenninates along a graduated stadia,and the water level at the stadia is the same as the level at the eservoir. Consequently,the floor elevation at designated data points throughout the structure could be meas ed relative to the elevation of the manometer reservoir. The elevation from the data points were adjusted for different floor covering elevations, and then reduced to reflect the elevation relative to the lowest points. The enclosed porch and .garage were surveyed separately. Approximate lines of equal elevations were dra n to the nearest tenth of an inch and are shown on the results which are attached in�pendix D.Fi zrg �•e 4 of t iis report. LAB RATORY TESTS Laboratory tests are commonly perfonned on soi samples to inore definitively establish their physical properties. Laboratory tests often inchide;organic content, noisture content,percent material finer than No.200 sieve,and Atterberg limits. Eight samples were tested to d tennine fines and moisture content and to detennine the correct classification. These sainples consisted of shallo clayey soils. The results of these laboratory tests are presented below in the Results section. RESULTS Ground Penetratin�Radar After receipt of the GPR report,tliis author revie ed the GPR survey results,including the digital profile imagery, to review the findings. Upon coinpletion of th invasive testing,the GPR digital profiles were reviewed again with the findings of the borings to re-evahiate t e initial interpretations of the GPR profiles. The GPR survey was perfoi7ned on the interio and exterior of the structure and did not identify any a�parent geologic features of interest.

Test pit TP-2 was excavated along the front ' side near the front right coiner of the residence and xposed a 10-inch thick spread footing bearing at a depth of approximately 21 inches. The footing extended 4 in ies beyond the exterior face of the exterior wall. Assuming the same projection of the footing beyond the interi r face of the exterior wall,the footing is estimated to have a width of 16 inches. The locations of the test pits ar shown on the Boring Location Plan in�pe»dix D.Fi.�zr�•e 1. Groundwater The groundwater level could not be determined du to the presence of the shallow clayey soils. The physical properties of clayey soils prevent accurate groundw ter level measurements. Clayey soils,as well as seasonal rainfall variations, rainfall runoff, and other site-s ecific factors, may cause groundwater levels to fluctuate significantly. Floor Level Survep Results The results of the floor level survey show that the s ab slopes slightly downward toward the right rear corner. The difference between the highest and lowest ineas red points was approximately 1.0 inch. The results of the separate converted garage survey show that the slab slopes approximately 1.8 inches downward from the right rear corner toward the front. Garages are typically c nstructed to slope downward toward the overhead door and � away froin the struchire to allow for drainage. The urvey performed of the enclosed porch shows that the slab slopes approxunately 2.6 inches downward from th front to the rear. Similarly to garages,porches are usually constructed to slope downward away from the stn cture to allow water to drain away. The detailed results showing lines of equal elevation are shown on A zdix D Fi n•e 4.

Sinkholes have typical characteristics which include ones of very soft or loose soil sediments that have washed downward into pre-existing cavern networks within t�ie bedrock. This very soft or loose soil zone is corrunonly called a raveling zone. The raveling zone originat s at the limestone surface as the overlying soils begin to collapse or inove vertically downward into the soluti n features within the liinestone. The loosening occurs in an upward vertical inotion until subsidence of the gr und surface occurs. The essential criteria for establishing the presence of sinkhole development as a probable ause of subsidence and structural damage include; • A cylindrical or cohimnar zone of very sof or loose soil that extends from the top of the limestone fonnation to the ground surface. • The presence of significant voids within the imestone. • A complete loss of drilling fluid circulation in the over-burden soils at significant distance above the liinestone fonnation. • A loss of soil density with increasing depth f penetration,generally observed for a distance of tens of feet. (the loss of soil density with increasing depth of penetration should be represented by a trend and not isolated individual samplings). • Stnicture dainage, a surface ground depre sion or other obvious observable indications of ground inovement inust be present in the immediate 1 cation. Generally when a structure is affected by sinkhole activity,the dainage is concentrated in speci ic areas and not widespread. The presence of one of the individual characteristic above does not establish reasonable evidence of damage caused by sinkhole. Damage caused by sinkholes m ist include multiple criteria from above. Site Specific Conclusions The results of our exploration and the SPT borings p rfonned at this site encountered conditions consistent with the definition of sinkholes as described in the criteria rovided in the previous section of this report. SPT borings B-3,and B-41ost complete drilling fluid circulation at ignificant depths(21 and 32 feet)above the hard limestone foi7nation,which can be an indication of downward ra eling ofthe overburden soils. SPT boring B-1 experienced a slight loss of density with depth froin a depth of 23 to 48 feet,with N-values generally decreasing froin 23 to 2 blows per foot. The floor level survey showed that small amount of subsidence inay have occurred at the right rear corner of the structure. Based on the results of this exploration,it is our pr fessional opinion that sinkhole activity can not be ruled out as a possible contributing factor to damag at this residence, within a reasonable professional probability. The cracks in the driveway and front porch tile,as we 1 as the hairline cracks in the terrazzo floor,are apparently the result of concrete shrinkage,which is common an occurs when concrete shrinks as it dries/cures. There are not adequate control joints in the driveway. Contro' joints are typically placed in concrete slabs to provide a location for shrinkage cracics to occur. Control jo nts should be spaced no fiirther than 8 feet apart in the horizontal and vertical directions of concrete slabs. Guilarte Residence-Claim No.354110 ' HCE Report No. 100091.1 Page No. 10 Our investigation is not of sufficient scope to develo a remediation plan for the non-sinkhole identified cause(s) of damage. RECO MENDATIONS i i T ical re airs for sinkhole dama e involve compa tion grouting at the top of the limestone formation,followed YP P g b re eated injection of grout through the soil layer above the limestone. The purpose of compaction grouting Y P is to seal voids in the limestone formation and coinp ct soils loosened by the downward vertical raveling into the voids in the limestone. Where settlement of the sla and foundation has occurred due to the presence of sinldiole activity,compaction grouting frequently restores th slab and foundation to near original construction elevations. However,while this is a desirable effect,there is n certainty that compaction grouting will reverse inovements that have already occurred. We recommend compaction grouting be performed round the perimeter of the house utilizing alternating vertical and angled grout injection holes. The holes should xtend through the overburden soils and be tenninated in the limestone formation. The angled holes should be irected below the stnicture, and the vertical holes placed as close as practically possible to the structure. Verti al and angled grout holes should be spaced on approximate 10-foot centers. A Coinpaction Grouting Specification (A endix ) and Preliininary Grout Hole Location Plan (�pendix G, Fi�an�e 1)are attached. These should be used as a uide for ground modification contractors. This specification should be used to assist the grouting contractor wi i pricing and preparation of a work scope. Contractors may inodify the work scope and suggest alternate scope as they feel appropriate. All inodifications to the suggested work scope inust be approved by the geotechnicai ngineer prior to commenceinent of worlc. ' ween a roximatel We estimate that approxunately 1,300 lmear feet f grout hole casmg will be mstalled bet pp y ' 16 grout holes. We also estimate that a total of ap roximately 225 cubic yards of grout will be injected into the grout holes. These estiinates are provided to assist ontractors with the planning of the work scope and obtaining permitting. We do not know what the final number of grout holes will be,nor do we do not lcnow how deep each grout hole will go. We also do not know how in h grout will need to be injected into each hole. The actual ainount of casing installed and grout injected inay significantly differ from these estimates. The compaction grouting process will compress an compact overburden soils below the home. These soils will contain water which is trapped temporarily duri g the grouting process. This water, known as hydrostatic pressure,takes time to dissipate. As it dissipates,tl e soil zone containing the elevated hydrostatic water pressure will continue to compress. Althotigh hydrostatic ater pressure usually dissipates within 3 to 4 weeks, clayey soils and organic soils may have much longer stabil zation durations. At the Guilarte residence,we anticipate that significant cosmetic damage may occur after rep irs are perfoi7ned if a 4-week delay between grouting and cosmetic repairs is not observed. Based on the quautities of casing and compaction�rout projected to reinediate sinkhole activity at tl�is site,we estimate that the project will require 12 work days t complete. Costs for grout injection are estimated as follows: 1Vlobilization: $ 2,500 Casing Installation: ,300 linear feet @$17/ft $22,100 Grout Injection: 25 cubic yards @$170/yd $38,250 � , � � Guilarte Residence-Claim Na.35411Q HCE Report No. 100091.] Page No. 11 Monitoring: 8 hrs/day x 12 days @$55/l�r $5,280 Tl�ese quantities are only estimates. Sate logist'c canstraints, contractor methodology, supplier reliability, equipment reliability, subsurface conditions, etc., can affect tlle duration of wark and q�iantzties of materials required. It is common far actual sinkliole valu es to deviate by 30 to 50 percent from the estimate. The variation may be mo��e ar less than the estiinate. Si ni�cantly larger variations,tlzough t�ncam�non,do occur and are NOT LIKELY FORESEEABLE.

(SB� has conducted a Ground.Penetrating Radar (GPR) survey at,the-;aUo.ve-rcfereuced property. This GPR survcy was performcd on August 26; ZOTO. The-subjece,site eonsisted of a singlestory residentiat weliing with a c�ncrete �atio located on tlie rear ofthe r�sidence at the southeast corner. The purp�se of the GPR sui-vey w��.s to document the_ atei�dl confiiiuity of soi] layers around aud bencati� the residence for a cause-of-stibsidei�ce investigation. Thc objcstivc af the survey �vas f� assist in positioning soil test borings above passible geolo�c fealures of interest This report is subject to the limitations.on Attachment A. GPR Surve IYleth�ds Y The survcy was perfarmed using a SIR-2000 di�tal e nirol unit and � 270-megahertz (MHz) antenna. Tliis GPR equipment is manufactui�ed by Geophysical Sur y Systems; Inc., North Salem, New Hatnpshire. Thc 27Q-MH� antevna coFnbines moderate resolutiou wi h moderate cicptli of penc[ration. The CPR survey equipment was used to i-�cord profiles thal represe t virtual cross-sections of the subsurFace canditions underlying the sm•vey h•ansect ]ines. SEI Staff Ge ]ogist and Certitied GPR Operator, Jonathan �'Vclker performed tl2e survcy. Following the completion of iiiitia] calibration tcsts, thc rangc of tlic 270-MHz antenna was set to l44 � na�ioscconds (ns)for scaunin�the interior of tl�e reside ce.

The gencra] tret�d in the d�ta is ihe presence of a gcncrally hori�vntal xnd cot�tinuous soil layer fi�om Uetween 30 to lUU ns across thc site. The GPR signa s were mnstly attenuated 6clow this time range. Uur review of the GPk data r.ecorded at the site c#i nut appear to iiidicatc tIie presence of apparent geologic features �f inte�•est relative Eo a cause-o€=subsidence investigation. The reflections from thc GPR transects did not appear to exhihit high .amplilude, stackcd, hy, er6alic retlections at depth, which are typical for karst er�sion. There was no agparent downwarping or runcation of the GPR soil layer reflections noted on tlie j�rotiles wl�ich would suggest the presence af a�i�a nt sinkhole development at the.site. Li conclusioii,.it is. SEI's oginion, that there were no aUivpt changes-i the lateral contiliuity of the i�eflections that are likely to rep��esen�subsurface fcatures associated with active. �arst erosiori.

These sinkholes than 200 feet, contributes to many of the modern sinkholes. For are only a few feet in diameter and depth. Their small size is due to the example, the lack of sinkholes in metropolitan Manatee and Sarasota fact that the cavities in the limestone cannot develop to appreciable counties can be attributed to the depth to limestone which is generally size before they are filled with sand. greater than 100 feet.The thick sequence of sand and clay above the limestone, shown in the cross-section on page 1, seems to support this observation. � �:�' �,��'��',�'�;1��: �i'r�'(�`1���,�'���'r�,�°; Whether natural or induced, there are several types of sinkholes. � � -�����•-'���'�f�"='�:��``-, == ":`��'`"`a �{`';,�='""°'.

GENERAL SP CIFICATIONS FOR COMPACTIO GROUT INJECTION ' Scope of Work The work discussed in this section consists of proj ect control,supervision,labor and equipinent,and performance of operations in connection with im�rovement of so'Is by injection of compaction grout. General 1. The placement of compaction gro t within the soil shall act to fill voids and compress and consolidate surrounding soils in s ich a way as to reduce the potential for firture sinldiole development. Mortar grouts shall e used which have a maxin7uin slump of 3 inches. Sluinps eater than 3 inches shall not be us d on this ro'ect unless a roved in advance b the ro'ect �' P J PP Y P J engineer. I 2. Soil improvement shall consist of i 'ection of low slump compaction grout at such locations as necessary to fill voids within the li estone and above the liinestone formation at the site, and coinpact overlying soil loosened by previous sinkhole activity. Materials 1. Portland Ceinent to be used on this roject shall be in coinpliance with current ASTM Standard C-150. 2. Fine aggregate shall be nariiral san material. The fine aggregate shall contain no less than 10 percent and no inore than 30 perce t passing the No. 200 sieve and shall be approved by the geotechnical engineer. 3. Water shall be obtained froin a clea potable water source. 4. Ready Mix Grout is acceptable con 'ngent on puinpability and consistent sluinp. Equipment 1. Only approved pumping and mixin equipment shall be used for preparation and handling of compaction grout. Contaminants st cl� as oil or rust inhibitors shall be removed from mixing dnims,stirring mechanisms,and all other equipment that may be in contact with the grout. 2. Compaction grout pumps shall be c pable of achieving 800 psi injection pressures and have a variable range of speeds between 1 nd 10 cubic feet per minute. 3. The mixing equipment shall have s ales, gauges, meters, or other calibrated devices for the , puiposes of monitoring the quantity of all components of tl�e grout mix. 4. Approval of equipinent on the job si e does not imply final acceptance. 5. The conhactor shall provide vertica survey control at each injection point to determine when surface heave has occurred. Mix Proportion 1. Materials used shall be accurately neasured by vohune,by weight,or other methods approved prior to commencing work. 2. The grout shall include a minimui of 12 percent cement based on the dry weight of sand, (i.e. 1001bs. of sand require a miniinui of 12 lbs. of ceinent). 3. Calibration of mixing devices and rout pumps shall be required as directed by the geotechnical engineer. 4. Ready Mix tickets, if Ready Mix i used, shall be saved and used for coinparison purposes. 5. The proposed inix design shall b submitted to the geoteclmical engineer for approval. The contractor is responsible for mix s rength,pumpability,etc. 6. The grout shall have a ininimum o-day compression strength of 200 psi. Injection point spacing and placement 1. The primary injection points shall be installed on 10-foot centers around the perimeter of the building. If necessary,secondary nd tertiary injection pipes shall be placed and grouted. The geotechnical engineer should esta lish the need for secondary or tertiary injection pipes as the grouting work proceeds. 2. All spacing changes shall be det nnined by grout quantity and grout pressures under the direction of the project engineer. 3. Injection pipes shall be drilled th ough the surface soil to at least 5 feet into the limestone fonnation. Generally,holes are ex ected to vary in depth froin 70 to 90 feet or inore total depth. The depths may be varied by the p oject engineer during the field operations to whatever depths deeined necessary. 4. Rotary wash drilling is acceptabl ; however, subsidence dainage that inay occur will be the responsibility of the contractor to epair at his own risk. 5. The diameter of the injection pipe hall be adequate to pennit injection of compaction grout. A miniinuin 2-inch inside diaineter i�e shall be used. 6. For all types of injection points accurate installation records shall be inaintained by the contractor including location an depth of injection points, method of installation and all pertinent data such as difficulties ncountered during drilling or driving. Compaction Grout Lijection Procedures 1. Compaction grouting shall procee around the perimeter of the dwelling with spacing of primary inj ection points on 10-foot centers. Priinary inj ection locations should alternate between vertical and angled points. A Preliminaiy rout Hole Location Plan(Appendix G.Fi�zn•e 1)is attached. The contractor shall submit a fi al grouting plan for review by tl�e geoteclinical engineer prior to commencement of field vork. • � Y 2. The inj ection of grout shall begin t the bottoin deptl�of the bored or drilled casing and proceed upward in two foot intervals. 3. Injection at eacl�interval shall co tinue until one of the following occurs: a. Miniinum grout pressure of 100 psi increase over pressure necessary to initiate grout intake. b. Maximum grout pressur of 250 psi or as directed by the geotechnical engineer. c. Maximuin grout quantit of 2 cubic yards per 2-foot intervals or 10 cubic yards at full drilled deptll. d. Maximum 25 cubic yard shall be placed at each injection point. e. Ground surface heave o curs. 4. Grouting shall take place froin t ie bottom of the grout hole upward to within 20 feet of the ground surface unless otherwise irected by the engineer. 5. Accurate records shall be mainta ned by the contractor for grout inix proportions, quantities of grout take,and injection pressur s. The actual sequence of grouting operations and proportion of grouting inix shall be herein rovided, except that the provisions may be modified by the geotechnical engineer as require by field conditions. 6. All daily drilling, grouting, and esting reports shall be subinitted to the geoteclmical engineer within 24 hours of completion o that work. 7. Drilling reports shall be require and shall contain at least the following information: name of driller,type of drill and inethod eing used,date started,date coinpleted,location of hole,type and depth of inaterials encou tered, and any notations regarding abnonnalities such as unexpected difficult drilling,etc 8. Grouting reports shall be inainta ned Uy the geotechnical engineer and shall contain at least the following information: name of routing technician,constituents and proportions of grout,log of quantity injected per lineal fo t of hole,date,rate of pumping and pressure at the hole. 9. A level control system shall be nstalled and operated by the contractor during grouting. The monitoring shall be carried out so as to detect any movement within 25 feet of the grouting operations whenever grouting is occuning. 10. Any work perfonned by the cont•actor without representation of the geoteclmical engineer shall not Ue compensated and process s shall be repeated. Testing and Quality Control 1. The testing and on-site monitori g shall be performed by the geotechnical engineer. His activity shall include but not be liinited o oUservin�the grouting activities, monitoring grout volumes and depths, and retaining and re iewing daily grout samples. 2. A minimum of three 3-inch x 6-inch grout sample cylinders shall be prepared each day.
