the foundation, or will the owner’s architectural firm be responsible for this? The greenhouse manufacturer via the general contractor will be responsible for the engineered signed

and sealed drawings. 2. What are the specifications for the clear fabric used in the Germplasm Cool House Energy

Curtain System? Energy Curtains (No Substitute): Wadsworth Slope-Flat-Slope energy/shade push-pull system is to be

included in each of the four growing areas. Each system will operate independently, controlled by the

ADDENDUM 4 September 25, 2012 Enviro-Step controller in each greenhouse growing area. Shade factor of fabric is to be XLS 13

Firebreak fabric as manufactured by Ludvig Svenson Company. In the east, air-conditioned greenhouse only, the system will pull a clear fabric when in open position and the XLS 13 Firebreak shade cloth when in the closed position. Also, add the Clear Energy Fabric in CGIP’s Cool Greenhouse should be Svensson flame-retardant energy saving material, XLS10 Revolux made of 100% polyester.

3. For the Budwood Greenhouse range, is the Svensson OLS 70 supposed to cover the insect

screening as well? Yes, the shadecloth will also need to be the Svensson product. 4. What sensors are required with the Microgrow Procom Growmaster series automatic control? The main functions are temperature control and the ability to activate fans and sump pumps. All of the

information necessary is included with the Procom system. The contractor should contact Microgrow for other information.

5. What sensors are required in the Germplasm greenhouse for the environmental controls (soil

moisture, light, temp humidity, etc.)? The main functions are temperature control and the ability to activate fans and sump pumps. 6. Will the owner/architect accept a 6/12 pitch instead of a 3/12 pitch? Bows will need to be 30’. The pitch can be changed as long as the gutters can handle the roof runoff

without flooding the house. 7. Are the heaters in the greenhouse LP gas or Natural gas. The heaters are LP. 8. Is an IGROW 1400 controller by Link4 an acceptable substitute for the Four Wadsworth

Envirostep control systems and the Four Sterling 18 station irrigation controllers? No. Use the Wadsworth STEP50A. 9. Will fans with galvanized steel housing and aluminum shutters be acceptable on the exhaust

fans? No. 10. I noticed the control specifications (15900) for Budwood and Germplasm indicate the control

manufacturer as “Computrol” only. Can other be acceptable? Yes, see attached revised section 15900. 11. In regard to the order and organization of the drawings, did you intend to provide two sets of

separate drawings, one with the Budwood, and the other with the Germplasm? Or, were your intentions to provide one complete set of drawings? I did refer to the list of drawings on each cover sheet, but I also noticed some discrepancies with the drawings listed and the drawing pdfs that were provided. I would only like to know how it is that you intended on arranging and organizing the drawings.

One project with two separate buildings and two greenhouses with one alternate greenhouse.

ADDENDUM 4 September 25, 2012 12. On the Germplasm building drawings, the index shows civil drawings that were not included with

the drawings. Civil drawings were available after the architectural plans and are available at the printer (ARC,

Gainesville, 3239 SW 47 Ave Suite 300, Gainesville, Florida 32608; Telephone (352) 371-5772, (352) 371-1188; [email protected]).

13. The index also does not show a sheet M400 which was provided with the set. Civil drawings were available after the architectural plans and are available at the printer (ARC,

Gainesville, 3239 SW 47 Ave Suite 300, Gainesville, Florida 32608; Telephone (352) 371-5772, (352) 371-1188; [email protected]). This sheet should be included as part of the set.

14. The Budwood drawings index does not show sheet G001 which was included with the set. Civil drawings were available after the architectural plans and are available at the printer (ARC,

Gainesville, 3239 SW 47 Ave Suite 300, Gainesville, Florida 32608; Telephone (352) 371-5772, (352) 371-1188; [email protected]). This sheet should be included as part of the set.

15. Missing civil drawings and update the drawing indexes. See #’s 12, 13 and 14. 16. Please confirm that all appliances and growth chambers will be provided and installed by owner. The appliances and growth chambers will be provided and installed by owner. 17. Conference Room 107 shows a projector and screen. Are these owner furnished items? Yes, owner will furnish; general contractor to install. 18. Please provide a specification and schedule for all of the signs needed for this project. Please provide a $2,500 sign allowance. 19. It seems that the HVAC control contractor on the plans is out of business or something’s up. Is

ok to have other companies price this work? The name of the company in the plans should be deleted. The general contractors and his sub-

contractors will be doing the work. 20. Per Sheet 6 of 13 (Paving, Grading & Drainage Plan) – note #1 at bottom of page refers to soils

report. There is no soils report in the spec book please provide.

Attached please see soils report. 21. Per sheet 5 of 13 (Site Plan ) & thru-out civils/ landscaping showing this - there is note for weed

mat that references the architectural Plans and specifications- when you go to the A drawings it shows concrete instead of weed mat. Are we to bid per civil drawings or architectural. If civil, please provide detail for the weed mat / stone that is on it etc. If Architectural, please provide overall site plan showing concrete work for the site not just at buildings. Layout / design between civils & architectural do not match in all area’s.

shown on the architectural plans as concrete shall receive 6’ min. of weed mat as per the civil documents.

mailto:[email protected]



ADDENDUM 4 September 25, 2012 22. An automatic irrigation system is specified to be installed, but I do not see an irrigation plan or

specifications for the system. Is this to be designed and installed by the contractor, or am I missing sheets in the project documents?

It will be installed by owner. 23. There are no sod areas indicated on the Landscape Plan. It seems a good portion of the site will

be disturbed, so could you clarify what (if any) areas are to be sodded and what type of sod is to be used?

The disturbed areas of the project shall be priced with bahia sod throughout. Please provide a line item

price for this work. An alternate price will be provided to provided seed and straw protection in the general areas and bahia sod at the perimeter of greenhouses and buildings.

24. Addendum 1 in “clarification on Budwood and Germplasm buildings” #5, says the storefront

doors to be “as” per note 5 on sheet A601.1. That note says they are Kawneer 190 narrow stile doors. Is this a closed spec, or will Vistawall or YKK be allowed? They both make an identical door, with Florida Product Approvals, to the Kawneer door.

This is not a closed spec. Other door manufacturers are allowed. 25. Can you please address issues of drainage from the Germplasm Greenhouses (to include drains,

traps and treatment) which were not included in Addendum 1? At the end of the center trench drain system that exits out of the greenhouse, a full size pvc pea trap

(similar to a sink) should be provided that would prevent insects from entering (walking/crawling or flying) from the exterior to the interior of the greenhouse.

26. Addenda No. 1, Item # 8 under clarification for the greenhouses - Previous descriptions for doors

were 3’0” x 6’8” galvanized. The doors should be aluminum, not galvanized. 27. Specification 15080.3.10 - Mechanical Insulation calls for the flexible duct wrap to be 2” thick x

1.5 lb/ft³density (installed R-6.4) and the rigid board duct insulation to be 2.0” thick x 1.5 lb/ft³ (installed R-8.3). In the insulation industry, the following would provide from 15-25% first cost savings while giving a greater installed R-Factor as follows. We would propose to install flexible duct wrap to be 2.25” thick x .75 lb/ft³density (installed R-6.5) and the rigid board duct insulation to be 2.0” thick x 3.0 lb/ft³ (installed R-8.7). In the case of the flexible duct wrap, the thickness is giving the greater R-Factor and the industry standard of using the 2.25”x.75# wrap contributes to the decreased first-cost. In the case of the duct board, the higher density is giving the greater R-Factor and since the 2.0”x1.5# board comes without a jacket, the 2.0”x3.0# board with jacket contributes to the decreased first-cost.

We would respectfully request to use the recommended insulation as outlined. 28. We would respectfully request direction for the Building Automation System. TLC Response dated 9/18/12 as follows: Trane, JCI, FIS, Alerton, Automated Logic, Siemens are

acceptable.

ADDENDUM 4 September 25, 2012 29. Can you please clarify the requirement for the “motorized dampers” or “exhaust fan dampers” in

the Budwood indexing greenhouse and the alternate? “Motorized and/or Exhaust Fan Dampers” shall be Tamco Series 1000SW, 56" x 56", with Belimo 120V

spring return actuators. 30. Germplasm and Budwood– Roof Mounted Exhaust Fans.

a. None shown on roof plan. Mechanical plans show fans on the roof. b. No structural supports shown. Trusses to be reinforced to accept the weight of the roof exhaust fans and curb. c. Will a Service platform and railing be required? No service platform or railing will be required. d. How will access to the roof be obtained? Access to the roof will be provided via ladders. e. EF-2 – Noted on plan sheet M201 to be located on the roof however it appears that the fan

is actually drawn as an in-line. Which one is correct? The fan is an in line fan.

31. Is a 12’ wide x 55.4’ long 4” thick concrete slab required, just south of the germplasm building

and the greenhouse and the crushed stone service drive? Yes, the slab is shown on the civil plans on sheet 5 of 11 and shall be 4” – 3000 psi concrete and reinf’d

with 6 x 6 wwm over 6 mil visqueen over 98% compacted earthen fill dirt with a broom finish, slope away from building and greenhouse.

32. The wall section for both the Germplasm and the Budwood buildings, where suspended

acoustical ceilings occur, illustrate and call out R-30 kraft faced fiberglass insulation with netting connected to the bottom of the wood trusses.

In lieu of what is illustrated and specified, provide un-faced R-30 fiberglass batt insulation over Tyvek

house wrap secured to bottom of trusses. 33. What size ducts are to be used for the following areas?

a. Germplasm - Rectangular upstream of EF-5: 14 x 12 b. Germplasm - Downstream of 24/14 from EF-2: 16 x 14 & 12 x 12 c. Germplasm - Downstream of 12/12 from SF-1

1.0 INTRODUCTION

1.1 General

GSE Engineering & Consulting, Inc. (GSE) has completed this geotechnical exploration for the proposed LaCrosse Citrus Repository located in LaCrosse, Alachua County, Florida. Our exploration was performed in accordance with GSE Proposal No. 2011-137 dated July 20, 2011. You authorized our services on July 28, 2011.

1.2 Project Description

We understand this project will consist of office buildings and greenhouses located in LaCrosse, Alachua County, Florida. The site is located along the west side of State Road 121 in the north portion of LaCrosse, Florida. Figure 1 illustrates the project location.

You furnished us with a preliminary site plan showing the proposed building layouts and locations along with information about the project. We understand that the project will include a Budwood office building, Germplasm office building, two greenhouses, a driveway and parking lot, and a stormwater management facility.

The office buildings are expected to be single-story, concrete masonry unit (CMU) construction, and the greenhouses are expected to be pre-engineered, steel frame construction. The Germplasm greenhouse will have a concrete floor, while the larger greenhouse will not.

The Budwood structure will have an approximate footprint of 132 by 132 feet. The Germplasm office will have dimensions of about 48 by 105 feet. Structural loads of 2 to 3 kips per linear foot for walls and up to 30 kips for columns are anticipated. We anticipate the finished floor will be constructed within 2 feet of the existing grades.

The greenhouse structures will be open-air, steel frame construction. Column loads of up to 50 kips are anticipated. The Germplasm greenhouse will have an area of about 24,000 square feet, and the larger greenhouse will have an area of about 60,500 square feet.

You provided a preliminary site plan indicating the location of the proposed office buildings and greenhouses, driveway, parking lot, and stormwater management facility. In addition, a recent aerial photograph was also obtained and reviewed. We used the provided site plan and aerial photograph in the preparation of this exploration and report.

1.3 Purpose The purpose of this geotechnical exploration was to determine the general subsurface conditions, evaluate these conditions with respect to the proposed construction, and prepare geotechnical recommendations to assist in the design of the building foundations, pavements, and stormwater management facility.

2.0 FIELD AND LABORATORY TESTS

2.1 General Description

The procedures used for field sampling and testing are in general accordance with industry standards of care and established geotechnical engineering practices for this geographic region. Our exploration consisted of performing eleven (11) Standard Penetration Test (SPT) borings to depths of 20 feet below land surface (bls) and four (4) auger borings to depths of 10 feet bls within the proposed building areas, three (3) auger borings to depths of 5 feet bls within the driveway and parking lot, and five (5) auger borings to depths of 15 feet bls within the area of the stormwater management facility.

The soil borings were performed at the approximate locations as shown on Figure 2. We located the borings at the site using the provided site plan and obvious site features as reference. You should consider the locations approximate. The soil borings were performed between the dates of August 22, 2011 and August 25, 2011.

2.2 Auger Borings

The auger borings were performed in accordance with ASTM Specification D-1452. The borings were performed with flight auger equipment that was rotated into the ground in a manner that reduces soil disturbance. After penetrating to the required depth, the auger was retracted and the soils collected on the auger flights or from the auger bucket were field classified and placed in sealed containers. Representative samples of each stratum were retained from the auger boring. Results from the auger borings are provided in Section 5.2.

2.3 Standard Penetration Test Borings

The soil borings were performed with a drill rig employing mud rotary drilling techniques and Standard Penetration Testing (SPT) in accordance with ASTM Specifications D-1586. The SPTs were performed continuously to 10 feet and at 5-foot intervals thereafter. Soil samples were obtained at the depths where the SPTs were performed. The soil samples were classified in the field, placed in sealed containers, and returned to our laboratory for further evaluation.

After drilling to the sampling depth and flushing the borehole, the standard two-inch O.D. split-barrel sampler was seated by driving it 6 inches into the undisturbed soil. Then the sampler was driven an additional 12 inches by blows of a 140-pound hammer falling 30 inches. The number of blows required to produce the next 12 inches of penetration were recorded as the penetration resistance (N-value). These values and the complete SPT boring logs are provided in Section 5.1.

Upon completion of the sampling, the boreholes were abandoned in accordance with Water Management District guidelines.

2.4 Soil Laboratory Tests

The soil samples recovered from the soil borings were returned to our laboratory, and examined to confirm the field descriptions. Representative samples were then selected for laboratory testing. The laboratory tests consisted of seven (7) percent soil fines passing the No. 200 sieve


2-2

determinations with natural moisture contents and three (3) constant head permeability tests. These tests were performed in order to aid in classifying the soils and to further evaluate their engineering properties. The laboratory tests are provided in Section 5.3.

3.0 FINDINGS

3.1 Surface Conditions

Messrs. Jesse J. Jannette E.I. and Jason E. Gowland, P.E. visited the site on August 15, 2011 to observe the site conditions and mark the boring locations.

We understand the parcel was recently cleared. The site is mostly open grass and weed covered. Small to large trees are scattered along the perimeter of the site. Burned debris was observed at the surface in a few areas of the site. The eastern side of the site is bordered by State Road 121. The western side of the site is bordered by Old State Road 121-A (abandoned). An existing fire tower is located in the northwestern portion of the property. A wooden fenced-in area is located at the northern extent of the parcel. The preliminary site plan indicates underground propane tanks are located in the western to northwestern portion of the site.

The topography at the site is gently sloping downward from west to east with the regional topography being gently sloping downward to the northeast. The LaCrosse USGS Topographic Map indicates the ground surface elevations at the site are near elevations 125 to 135 feet1 NGVD.

3.2 Subsurface Conditions

The locations of the SPT and auger borings are provided on Figure 2. Complete logs for the borings are provided in Sections 5.1 and 5.2. Descriptions for the soils encountered are accompanied by the Unified Soil Classification System symbol (SM, SP-SM, etc.) and are based on visual examination of the recovered soil samples and the laboratory tests performed. Stratification boundaries between the soil types should be considered approximate, as the actual transition between soil types may be gradual.

The SPT and auger borings indicate the soil conditions across the site are relatively consistent. The auger borings performed in the proposed building, driveway, parking lot, and stormwater management facility areas encountered sand with silt (SP-SM) and silty sand (SM) to the respective boring termination depths.

The SPT borings performed within the proposed building areas generally encountered sand with silt (SP-SM) and silty sand (SM) in the upper 12 to 19 feet bls. These surficial soils were underlain by silty sand with clay (SM-SC) to the 20 feet bls boring termination depth in borings B-2, B-5, B-7, B-8, B-9, and B-10. SPT boring B-1 encountered clayey sand (SC) underlying the silty sand with clay (SM-SC) layer. The surficial sand with silt (SP-SM) and silty sand (SM) strata were underlain by sandy clay to clay with sand (CL/CH) to the 20 feet bls boring termination depth in borings B-3, B-4, B-6, and B-11.

The SPTs performed indicate the surficial sand with silt (SP-SM) and silty sand (SM) encountered to depths ranging from approximately 12 to 19 feet bls are generally in a loose to medium dense strength soil condition with N-values ranging from 4 to 29 blows per foot. 1 DeLorme Topo USA® 6.0, Alachua Quadrangle, 1981.


3-2

Isolated very loose soil conditions were encountered within the silty sand (SM) stratum in B-1 and B-7. The underlying silty sand with clay (SM-SC) is generally in a loose to dense condition, with N-values of 7 to 35 blows per foot. The exception occurred in B-8, which encountered very dense silty sand with clay (SM-SC) with an N-value of 70 blows per foot. The clayey sand (SC) encountered from approximately 17 to 20 feet bls in B-1 is medium dense, with an N-value of 29 blows per foot. The deeper sandy clay to clay with sand (CL/CH) encountered in borings B-3, B-4, B-6, and B-11 is stiff to very stiff, with N-values ranging from 12 to 22 blows per foot.

The groundwater table was encountered in each of the SPT borings and in auger borings A-1 through A-4 and P-1 through P-5 at depths ranging from approximately 4 to 5.5 feet bls at the time of our exploration. The groundwater table was not encountered in the driveway and parking lot auger borings (R-1, R-2, and R-3).

3.3 Review of Published Data

The Soil Conservation Service (SCS) Soil Survey for Alachua County2 maps one soil series in the general vicinity of the site consisting of Zolfo sand. The following soil description is from the Soil Survey.

Zolfo sand – This nearly level, somewhat poorly drained soil is on slight rises of the flatwoods and in the rather broad transitional area between the rolling uplands of the western part of the county and the flatwoods of the eastern part. Slopes are nearly level and range from 0 to 2 percent. The areas are irregular in shape and range from 25 to 75 acres. Typically, the surface layer is dark gray sand about 8 inches thick. The subsurface layer is sand and extends to a depth of 60 inches. The upper 6 inches is grayish brown; the next 20 inches is pale brown with mottles; and the lower 26 inches is very pale brown and has mottles. The subsoil is dark brown to dark reddish brown sand to a depth of 82 inches or more. Included with this soil in mapping are small areas of Chipley, Pottsburg, Sparr, and Tavares soils. Also included are small areas of soils that are similar to the Zolfo soil, but have a water table at a depth of 40 to 72 inches during wet periods. Total included areas are about 15 percent or less.

This Zolfo soil has a water table that is at a depth of 24 to 40 inches for 2 to 6 months during most years and may be at a depth of 10 to 24 inches for periods of about 2 weeks or less during very wet periods. Surface runoff is slow. The available water capacity is low to medium to a depth of 60 inches and medium to high below this depth. Permeability is rapid to a depth of 60 inches and moderate below. Natural fertility is low. Organic matter content of the surface layer is low.

3.4 Laboratory Soil Analysis

Selected soil samples recovered from the soil borings were analyzed for natural moisture content, the percent fines passing the No. 200 sieve and vertical permeability. Selected soil samples were 2 Soil Survey of Suwannee County, Florida. Soil Conservation Service, U.S. Department of Agriculture.

collected from depths ranging from 2 to 10 feet bls. These tests were performed to confirm visual soil classification and evaluate their engineering properties. The complete laboratory report is provided in Section 5.3.

The laboratory tests indicate the tested soils consist of sand with silt (SP-SM). The sand with silt (SP-SM) had approximately 5.8 to 8.4 percent soil fines passing the No. 200 sieve and moisture contents of 8.7 to 19 percent.

The constant head permeability test results indicate the surficial sand with silt (SP-SM) has vertical coefficients of permeability on the order of 4 to 9 feet per day (1.30 x 10-3 to 3.34 x 10-3 cm/sec).

4.0 EVALUATION AND RECOMMENDATIONS

4.1 General

The following recommendations are made based upon our understanding of the proposed construction, a review of the attached soil borings and laboratory test data, and experience with similar projects and subsurface conditions. If plans or the location of proposed construction changes from those discussed previously, we request the opportunity to review and possibly amend our recommendations with respect to those changes.

In this section of the report, we present our recommendations for building foundations, pavements, stormwater management design, and our general site preparation guidelines.

4.2 Groundwater

The groundwater table was encountered in each of the SPT borings and in auger borings A-1 through A-4 and P-1 through P-5 at depths ranging from approximately 4 to 5.5 feet bls at the time of our exploration. We anticipate the normal seasonal high water table to be at depths of approximately 2 to 3.5 feet bls.

Temporary dewatering may be required for deep excavations and utilities. If construction proceeds during the wet season, we anticipate dewatering can be accomplished with underdrain pipes or well points connected to vacuum pumps. Localized dewatering can also be accomplished with sumps placed just outside the construction areas.

4.3 Building Foundations

The soil borings within the proposed building footprint indicate the soils at the site are consistent. The borings indicate approximately 12 to 19 feet of sand with silt (SP-SM) and silty sand (SM) overlying silty sand with clay (SM-SC), clayey sand (SC), and sandy clay to clay with sand (CL/CH).

Based upon the soil conditions encountered, we recommend the buildings be supported by conventional, shallow spread foundations. We recommend the shallow foundations be designed for a maximum net soil bearing pressure of 2,000 psf. Net bearing pressure is defined as the soil bearing pressure at the base of the foundation in excess of the natural overburden pressure. The foundations should be designed based upon the maximum load that could be imposed by all loading conditions.

The foundations should be embedded a minimum of 18 inches below the lowest adjacent grade. Interior foundations or thickened sections should be embedded a minimum of 12 inches. The foundations should have minimum widths of 18 inches for strip footings, and 24 inches for columns, even though the maximum soil bearing pressure may not be fully developed. The upper 24 inches of the bearing surface should be compacted to 95 percent of the Modified Proctor maximum dry density (ASTM D 1557).


4-2

Due to the mostly sandy nature of the majority of the near-surface soils, we expect settlement to be mostly elastic in nature. The majority of the settlement will occur on application of the loads, during and immediately following construction. Using the recommended maximum bearing pressure, the assumed maximum structural loads, and the field and laboratory test data which we have correlated into the strength and compressibility characteristics of the subsurface soils, we estimate the total settlements of the structure to be 1 inch or less, with approximately half of it occurring upon load application (during construction).

Differential settlement results from differences in applied bearing pressures and the variations in the compressibility characteristics of the subsurface soils. For the building pad prepared as recommended, we anticipate differential settlement of less than 1/2 inch.

Post-construction settlement of the structures will be influenced by several interrelated factors, such as (1) subsurface stratification and strength/compressibility characteristics of the bearing soils; (2) footing size, bearing level, applied loads, and resulting bearing pressures beneath the foundation; (3) site preparation and earthwork construction techniques used by the contractor, and (4) external factors, including but not limited to vibration from off-site sources and groundwater fluctuations beyond those normally anticipated for the naturally-occurring site and soil conditions which are present.

Our settlement estimates for the structure are based upon the use of successful adherence to the site preparation recommendations presented later in this report. Any deviation from these recommendations could result in an increase in the estimated post-construction settlement of the structure.

4.4 Pavements

Overall soil conditions encountered by our borings at this site are suitable for supporting conventional limerock base and asphalt wearing surface pavements. We recommend a minimum 2 foot separation between the bottom of the pavement base course and the estimated seasonal high water table. Is this separation cannot be maintained, we recommend underdrains be considered to lower the water table. We have not been provided the anticipated traffic loading conditions; therefore, the following pavement component recommendations should be used only as guidelines.

4.4.1 Stabilized Subgrade

The stabilized subgrade should have a minimum Limerock Bearing Ratio (LBR) of 40, with minimum thicknesses of 6 inches for automobile parking lots and 12 inches for the entrance driveway. The stabilized subgrade can be imported material or a mixture of imported and on-site material. If a mix is proposed, a mix design should be performed to determine the optimum mix proportions. The stabilized subgrade should be compacted to a minimum of 98 percent of the Modified Proctor maximum dry density (ASTM D-1557) for soils with less than 15 percent fines content. Soils with 15 percent or greater fines content should be compacted to 100 percent of the Standard Proctor maximum dry density (ASTM D-698).


4-3

4.4.2 Base Course

The base course should consist of crushed limerock having a LBR of at least 100. Limerock should be obtained from a FDOT approved source, and should meet FDOT gradation requirements. The base course thickness should be a minimum of 6 inches in automobile parking areas, and 8 inches in driveway areas. The base course should be compacted to at least 98 percent of the Modified Proctor maximum dry density (ASTM D-1557).

4.4.3 Wearing Surface

The asphalt-wearing surface should consist of an FDOT Type SP Hot Mix Asphalt mixture. For automobile parking lots, the thickness should be at least 1.5 inches. For the driveways, the thickness should be at least 2.0 inches and consist of an SP-12.5 mix. The asphalt should be compacted to at least 95 percent of the mix design density.

4.5 Site Preparation

The soils at this site should be suitable for supporting the proposed construction using normal, good practice site preparation procedures.

4.5.1 Stripping

Strip the construction limits and 10 feet beyond the perimeter of all grass, roots, topsoil, pavement, burnt debris, and other deleterious materials. You should expect to strip to depths of 6 to 12 or more inches. Deeper stripping may be necessary if major root systems are present and went undetected as part of this investigation.

4.5.2 Dewatering

Temporary dewatering may be required for deep excavations and utilities. If construction proceeds during the wet season, we anticipate dewatering can be accomplished with underdrain pipes or well points connected to vacuum pumps. Localized dewatering can also be accomplished with sumps placed just outside the construction areas.

In any case, the site should always be graded to promote runoff and limit the amount of ponding. Localized ponding of stormwater is expected without proper grading during construction, and could render previously acceptable surfaces unacceptable.

4.5.3 Proof-Rolling

Proof-roll the subgrade with heavy rubber-tired equipment, such as a loaded front-end loader or dump truck, to identify any loose or soft zones not found by the soil borings. The proof-rolling should be monitored by a geotechnical engineer or qualified technician. If compaction cannot be achieved, undercut or otherwise treat these zones as recommended by the geotechnical engineer in this report.


4-4

4.5.4 Proof Compaction

Compact the subgrade to a density of at least 95 percent of the Modified Proctor maximum dry density (ASTM Specification D-1557). The specified compaction should be obtained to a depth of 2 foot below the foundation bottoms and the existing grade prior to placing fill.

4.5.5 Fill Placement

Imported fill placed to raise the site grades should consist of clean sand having less than 10 percent passing the No. 200 sieve. On-site soils meeting the requirements of Section 4.7 may also be used as structural fill. The fill should be placed in maximum 12-inch loose lifts that are compacted to at least 95 percent of the Modified Proctor maximum dry density. If lighter “walk-behind” compaction equipment is used, this may require lifts of 4 inches or less to achieve the required degree of compaction.

4.5.6 Testing

Perform compaction testing in the subgrade and fill. One test should be performed every 50 linear feet of continuous footing and every other column footing, per foot depth of fill or native material. Perform a compaction test for each 2,500 square feet of floor area or 10,000 square feet of pavement area per foot of fill or native material, or a minimum of three tests each, whichever is greater. Test all footing excavations to a depth of 2 feet, at the frequencies stated above.

4.6 Stormwater Management

The soil conditions at the stormwater management facility are consistent with the building and parking borings. The borings encountered surficial sand with silt (SP-SM) and silty sand (SM) to the 15 feet bls boring termination depth.

The water table was encountered in the pond borings (P-1 through P-5) at depths of approximately 4 to 5 feet bls at the time of our exploration. We estimate the normal seasonal high water table at the site to vary from approximately 2 to 3.5 feet bls. We anticipate the normal seasonal high water table in the pond borings to be at approximately 2 to 2.5 feet bls. Considering the results of the auger borings performed in the stormwater management facility, coupled with the information provided in the soil survey and dry conditions experienced by the Alachua County area over the past several months, the water table encountered at the time of our site exploration is likely near the seasonal low water table. Therefore, we expect the normal seasonal low water table to be at approximate depths of 4 to 5 feet bls.

The laboratory permeability tests indicate the surficial layer of sand with silt (SP-SM) has vertical coefficients of permeability of 4 to 9 feet per day.

Based upon our findings and test results, our recommended soil and groundwater parameters for the proposed stormwater management area improvements are presented below. The recommended parameters consider the results of the permeability tests and wash 200 determinations, the permeability characteristics of the in situ materials, and our experience with these types of soils.


4-5

For the purpose of your modeling, we recommend the following soil parameters for stormwater management area design:

1. Base elevation of effective or mobilized aquifer >15 feet bls.

2. Unsaturated vertical infiltration rate of 7 feet per day.

3. Horizontal hydraulic conductivity of 10 feet per day.

4. Specific yield (fillable porosity) of 20 percent.

5. Normal seasonal high groundwater table of 2 feet bls.

A minimum factor of safety of 2 should be applied to the vertical infiltration and horizontal hydraulic conductivity values provided.

4.7 Fill Suitability

Some of the soils that will be excavated from this site are expected to be the surficial sand with silt (SP-SM) and are considered suitable for use as structural fill.

The deeper silty sand (SM) soils can also be used as structural fill, but these soils are a less desirable source of fill because they are moisture sensitive and more difficult to work and compact. If you wish to use the on-site silty sand soils we recommend they contain less than 30 percent soil fines (Passing the No. 200 sieve) with a Plasticity Index less than 10 and Liquid Limit less than 40. Mixing of soils with higher fines content with those with less fines content may increase their overall workability.

Any materials containing greater than 30 percent fines are not considered a suitable source of structural fill.

4.8 Surface Water Control and Landscaping

Roof gutters should be considered to divert runoff away from the building. The gutter downspouts should discharge a minimum of 10 feet from the structure to reduce the amount of water collecting around the foundations. Where possible, the gutter downspouts should discharge directly into the storm sewer system or onto the asphalt paved areas in order to reduce the amount of water collecting around the foundations. Grading of the site should be such that water is diverted away from the building on all sides to reduce the potential for erosion and water infiltration along the foundation.

With respect to landscaping, it is recommended that planted trees and large “tree-like” shrubbery with potential for developing large root systems be planted a minimum distance of half their mature height, and preferably their expected final height, away from the structure. The purpose of this is to reduce the potential for foundation or slab movements from the growth of root systems as the landscaping matures.


4-6

Consideration should also be given to using landscaping that has a low water demand, so that excessive irrigation is not conducted around the structures.

4.9 Potential for Construction Debris During our site visit trace amounts of asphalt and burned debris were observed on the surface of the site within the proposed building pad area. Our geotechnical exploration found no indicators of buried construction debris at the soil boring locations. However, if asphalt debris is observed during stripping and grubbing operations it should be removed from within the building and roadway limits.

6.0 LIMITATIONS

6.1 Warranty This report has been prepared for our client for his exclusive use, in accordance with generally accepted soil and foundation engineering practices, and makes no other warranty either expressed or implied as to the professional advice provided in the report. This exploration was confined to the zone of soil likely to be stressed by the proposed construction. Our work did not address the potential for surface expression of deep geological conditions, such as sinkhole development related to karst activity. If desired, this type of evaluation could require a more extensive range of field services than performed as part of this geotechnical investigation.

6.2 Auger and SPT Borings

The determination of soil type and conditions was performed from the ground surface to the maximum depth of the borings, only. Any changes in subsurface conditions that occur between or below the borings would not have been detected or reflected in this report.

Soil classifications that were made in the field are based upon identifiable textural changes, color changes, changes in composition or changes in resistance to penetration in the intervals from which the samples were collected. Abrupt changes in soil type, as reflected in boring logs and/or cross sections may not actually occur, but instead, be transitional.

Depth to the water table is based upon observations made during the performance of the SPT borings. This depth is an estimate and does not reflect the annual variations that would be expected in this area due to fluctuations in rainfall and rates of evapotranspiration.

6.3 Site Figures

The measurements used for the preparation of the figures in this report were made with a fiberglass tape and by estimating distances from existing structures and site features. Figures in this report were not prepared by a licensed land surveyor and should not be interpreted as such.

6.4 Unanticipated Soil Conditions The analysis and recommendations submitted in this report are based upon the data obtained from soil borings performed at the locations indicated on the Boring Location Plan. This report does not reflect any variations that may occur between these borings. The nature and extent of variations between borings may not become known until excavation begins. If variations appear, we may have to re-evaluate our recommendations after performing on-site observations and noting the characteristics of any variations.

6.5 Misinterpretation of Soil Engineering Report GSE Engineering & Consulting, Inc. is responsible for the conclusions and opinions contained within this report based upon the data relating only to the specific project and location discussed herein. If others make the conclusions or recommendations based upon the data presented, those conclusions or recommendations are not the responsibility of GSE.
