ESTABLISHED 1967 Offices throughout the state of Florida www.nuttingengineers.com.info@nuttingengineers.com September 17, 2001 Mr. Chff Melear Chairman BUIldmg ComrmssIOn First Baptist Church 301 North Seacrest Boulevard Boynton Beach, Flonda 33435 Phone: 561-704-9812 Fax: 561-735-9544 Subject: Report of Geotechmcal Exploration Proposed First Baptist Church Sanctuary 301 North Seacrest Boulevard Boynton Beach, Flonda Dear Mr. Melear: Nutting Engmeers of Flonda, Inc. has performed a geotechnical exploration for the proposed buIlding to be constructed at the above referenced sIte m Boynton Beach, Florida. The purpose of this exploration was to obtain informatIon concerning the site and subsurface condItIons in order to provide sIte preparatIon and foundation desIgn recommendations for support of the proposed construction. ThIS report presents our findmgs and recommendatIOns. PROJECT INFORMATION Based on dIScuSSIons wIth the structural engineer, plans call for the development of a multI- story sanctuary buIlding with offices. Structural speCIfications are not known at thIS time, but along WIth the building, Improvements will be made to the eXIsting asphalt paved parking lot and roadways. Based on current site elevatIOns and our knowledge of the area rmmmal fill will be reqUIred to bring the site up to grade GENERAL SUBSURFACE CONDITIONS Subsurface Soil Exploration The exploration of subsurface condItIons mcluded SIte observation, reVIew of the Palm Beach County SoIl Survey Map, Standard PenetratIOn Test bonngs (ASTM D-1586), and exfiltration tests. 2 1310 NEPTUNE DRIVE.

Miami-Dade (305) 557-3083 In order to explore the subsurface condItIons at the sIte, eIght (8) Standard PenetratIOn Test bonngs (ASTM D-1586) were performed to a depth of 15 feet below the eXIstIng ground surface. The locatIOns of the test bonngs are IndIcated on the attached Test Bonng Location Plan. IndIVIdual test bonng reports are presented In the AppendIx of thIS report. The test boring locatIOns were selected by the clIent. The bonngs were establIshed in the field using approXImate methods; namely, a measunng tape and aVaIlable surface controls. Soil Survey Maps Review The Palm Beach County soil survey maps IndIcate that the SIte consIsts SaInt Lucie fine Sand. ThIS series IS nearly level to sloping, excessIvely draIned, deep, sandy SOlI is on long narrow, dune-like coastal ridges and on Isolated knolls. A representative pedon contaInS a surface layer of gray sand about 5 inches thICk. Below this is whIte sand that extends to a depth of 72 inches or more. We note that the maximum depth of the survey IS SIX feet. Test Boring Results The test borings generally revealed a surface layer of loose to medium dense light gray sand to a depth of approximately eight to ten feet. This was underlaIn by loose to medIUm dense yellowish brown sand to fifteen feet, the maximum depth explored. We note that in locations where the borings were performed in eXIsting asphalt, the upper two feet of material represented road base and subbase. Exfiltration Test Results As part of the geotechmcal exploratIOn, three 'Usual Open Hole' exfiltration tests were performed in accordance WIth South Flonda Water Management DIStrict specificatIOns to a depth of six feet. The results of the exfiltration tests revealed the SOlIs at the location tested have a hydraulic conductivity (K-value) of 9.38 X 10-4, 1.17 X 10-3, and 4.84 X 10-4 cfs/ft2/ft of head. DetaIled flow rates and soIl descnptIOns are presented in the appendix. Groundwater The groundwater level was measured at the bonng locatIons at the tIme of dnlling. The groundwater level was encountered at an approXImate depth of twelve feet below the eXIstIng ground surface. FluctuatIOn in the observed groundwater levels should be expected due to seasonal clImatIc changes, constructIOn actIVIty, and other sIte-specific factors. ANALYSIS AND RECOMMENDATIONS The bonngs performed for thIS project revealed that the SOlIs WIthIn the upper SIX to ten feet are In a loose state. Because of thIS, In order to properly prepare the foundatIon SOlIs, some undercutting, and compaction wIll need to be accomplIshed pnor to construction. ~NUTTING ~ ENGINEERS OF FLORIDA INC ESTABLISHED 1967 3 Once the site IS prepared In accordance wIth the recommendations presented in thIS report, the sIte may be developed for the proposed bUIldmg usmg a conventional shallow foundation system designed for an allowable soIl beanng pressure of 3,000 pounds per square foot. We recommend that a stem wall WIth floatmg slab foundation be used to support the structure, rather than a monolIthIc type foundatIOn. We recommend a minimum width of 18 inches for contmuous footmgs and 36 inches for IndivIdual footings, even though the soil bearing pressure may not be fully developed in all cases. We recommend that the bottom of footIngs be at least 18 inches below the lowest adjacent finished grade. It is our opinion that the floor slab system may be constructed as a slab on grade. We recommend that a vapor bamer be placed between the soIl and concrete. We also recommend that the remforcing steel mesh be placed at the approXImate center of the placed concrete for tensile support. Settlement Analyses We have compared the field test data obtaIned In thIS exploration WIth our expenence with siIll1lar structures and empIrical relatIOnshIps for soil beanng and settlement. Using a soIl beanng pressure on the order of 3,000 pounds per square foot, we have estimated that the total settlement of the structure should not exceed approxImately one inch, upon successful completion of the recommended buildIng pad preparation procedures. DIfferential settlements should be approxImately one-half of the total settlement. Most of this settlement should occur upon the applicatIOn of the dead load dunng constructIOn. Site Preparation All construction debris (floor slabs, footmgs, tie beams, concrete block, abandoned utilities, etc.), grass, weeds, and root zones should be stripped and removed from the constructIOn area to a lateral distance of at least 5 feet beyond the proposed exterior buildIng lImits. Once the debris has been cleared, the soIls should be undercut to a depth of two feet. The undercut should begin at a Ill1mmum dIstance of two feet away from the eXIstmg bUIldmg. This must be done In order to aVOid potentially underminmg the existIng foundations. The excavated soils may be stockpiled for use as backfill. A representatIve of the geotechmcal engineer should observe the stnpped surface. Upon approval by the geotechmcal engineer, the stnpped surface should be wetted, and then compacted WIth at least twenty passes of a vibratory roller haVIng a Ill1mmum dynamic force of 10 tons. Also, the surface should be compacted untIl a denSIty equivalent to at least 98 percent of the modIfied Proctor maXImum dry denSIty (ASTM D-1557) IS achieved to a depth of at least 12 inches below the compacted surface. (@NUTTING ~ ENGINEERS OF FLORIDA INC. ESTABLISHED 1967 4 Structural fill needed to bring the sIte to construction grade may then be placed in lIfts not exceeding 12 Inches In loose thIckness when USIng the VIbratory compactIOn eqUIpment descnbed previously. Each lIft should be thoroughly compacted until densIties eqUIvalent to at least 98 percent of the modIfied Proctor maxImum dry densIty are uniformly obtained. FollOWIng site and buIlding pad construction as dIscussed above, the foundatIOn area can be excavated and the footIngs formed. The bottom of foundation excavatIOns should be compacted after excavation to develop a rmnimum density reqUIrement of 98 percent of the maXImum modIfied Proctor dry density, for a rmnimum depth of one (1) foot below the bottom of the footing depth, as determIned by field density compactIOn tests. The floor slab area should also be compacted in the same manor. Pavements Pavement areas should be compacted to a mimmum of 98 percent of the modIfied Proctor maximum dry density to a depth of at least 12 inches below the bottom of the subgrade level. We recommend that stabIlIzed sub grade having a rmmmum LImerock Bearing RatIO (LBR) of 40 IS placed to a depth of approxImately one foot below the base course. The base course should be at least 6 inches, and should have a rmmmum LBR of 100. GENERAL INFORMATION Prior to Initiating compaction operatIOns, we recommend that representative samples of the structural fill material to be used and acceptable In-place SOlIs be collected and tested to determIne theIr compaction and claSSIficatIOn charactenstIcs The maXImum dry density, optImum moisture content, gradatIon and plastiCIty charactenstIcs should be determined. These tests are needed for compaction quality control of the structural fill and existIng soIls, and to determIne If the fill material IS acceptable. A representative number of in-place field density tests should be performed in the compacted eXIstIng soils and In each lift of structural fill or backfill to confirm that the reqUIred degree of compaction has been obtained. If conditions are encountered which are not consistent WIth the findings presented In thIS report, or if proposed constructIOn is moved from the locatIOn studied, this office shall be notified immedIately so that the condition or change can be evaluated and appropnate actIOn taken. The vibratory compactIOn eqUIpment could cause VIbratIOns that could be felt by persons WIthIn adjacent buildIngs. The contractor should exercise due care dunng the performance of the vibratory compaction work. If such vibratIOns are not conSIdered tolerable, then alternate foundatIOn modificatIOn techniques should be conSIdered. ~NUTTING ~ ENGINEERS OF FLORIDA.

LIMITATIONS OF LIABILITY WARRANTY We warrant that the services performed hy Nutting Engineers of Rorida, Inc. are conducted in a manner consistent with that level of care and sluJJ ordinarily exerdsed hy members of the profession currently practicing under similar conditions. No other warranties, expressed or implied, are made. While the services of Nutting Engineers of Rorida, Inc. are a valuable and integral part of the design and construction teams, we do not warrant, guarantee, or insure the quality or completeness of services provided by other memhers of those teams, the quality, completeness, or satisfactory performance of con<;truction plans and specifications which we have not prepared, nor the ultimate performance of huilding site materials. SUBSURFACE EXPLORATION Subsurface exploration is normally accomplished by test borings; test pit<; are sometimes employed. The method of detennining the boring location and the surface elevation at the boring is noted in the report. TIlls information is represented on a drawing or on the boring log. The location and elevation of the boring should be considered accurate onJy to the degree inherent with the method used. The soil boring log includes sampling information, description of the materials recovered, approximate depths of bqundaries hetween soil and rock strata and groundwater data. The log represents condition<; specifically at the location and time the boring was made. The boundaries lJetween different soil strata are indicated at specific depths; however, these depths are in fact approximate and dependent upon the frequency of sampling. The transition between soil strata is often gradual Water level readings are made at the times and under conditions stated on the boring logs. Water levels change with time, precipitation, canal levels, local we]] drawdown and other factors. LABORA TORY AND FIELD TESTS Tests are performed in accordance with specific ASlM Standards unless otherwise indicated. All criteria included in a given ASlM Standard are not always required and performed. Each test report indicates the measurements and determinations actually made. @NUTTING ~ ENGINEERS OF FLORIDA. INC ESTABLISHED 1967 ANAL YSIS AND RECOMMENDA TIONS The geotechnical report is prepared primarily to aid in the design of site work and structural foundations. Although the information in the report is expected to be sufficient for these purposes, it is not intended to determine the cost of construction or to stand alone as a construction specification. Report recommendations are based primarily on data from test borings made at the locations shown on the test boring reports. Soil variations may exist between borings and may not become evident until construction. If variations are then noted, the geotechnical engineer should be contacted so that field conditions can be examined and recommendations revised if necessary. The geotechnical report states our understanding as to the location, dimension<; and structural features proposed for the site. Any significant changes in the nature, design, or location of the site improvements must be communicated to the geotechnical engineer so that the geotechnical analysis, conclusions, and recommendations can be appropriately adjusted. CONSTRUCTION OBSERVATION Construction observ~tion and testing is an important element of geotechnical services. TIle geotechnical engineer's field representative (G.E.F.R.) is the "owner's representative" observing the work of the contractor, perfonning tests and reporting data from such tests and observations. The geotechnical engineer's field representotive does not direct !he contractor's construction means, methods, opera- tions or personnel The G.E.F.R. does not interfere with the relationship between the owner and the contractor and, except as an observer, does not become a substitute owner on site. TIle G.E.F.R. is responsible for his/her safety, but has no responsibility for the safety of other personnel at the site. TIle G.E.F.R. is an important member of a team whose responsibility is to observe and test the work being done and report to the owner whether that work is being carried out in general conformance with the plans and specifications.
