Provisions for external cooling and seal flushing shall also be provided. The cooling system shall provide forcontinuous pump operation in liquid temperature of up to 104 DEGREES F. Restrictions below this temperature are not acceptable. CABLE ENTRY SEAL The cable entry seal design shall preclude specific torque requirements to insure a watertight and submersible seal. The cable entry shall consist of a single cylindrical elastomer grommet, flanked by washers, all having a close tolerance fit against the cable outside diameter and the entry inside diameter and compressed by the body containing a strain relief function, separate from the function of sealing the cable. The assembly shall provide ease of changing the cable when necessary using the same entry seal. The cable entry junction chamber and motor shall be separated by a terminal board, which shall isolate the interior from foreign material gaining access through the pump top. Epoxies, silicones, or other secondary sealing systems shall not be considered acceptable. MOTOR The pump motor shall be induction type with a squirrel cage rotor, shell type design, housed in an air filled, watertight chamber, NEMA B type. The stator windings and stator leads shall be insulated with moisture resistant Class F insulation rated for 155°C ( 311 °F).

The combined service factor -(combined effect of voltage, frequency and specific gravity) shall be a minimum of 1.15. The motor shall have a voltage tolerance of plus or minus 10%. The motor shall be designed for operation up to 400C (1040F) ambient and with a temperature rise not to exceed 80°C. A performance chart shall be provided upon request showing curves for torque, current, power factor, input/ output kW and efficiency. This chart shall also include data on starting and no-load characteristics. The power cable shall be sized according to the NEC and ICEA standards and shall be of sufficient length to reach the junction box without the need of any splices. The outer jacket of the cable shall be oil resistant chloroprene rubber. The motor and cable shall be capable of continuous submergence underwaterwithout loss of watertight integrity to a depth of 65 feet. The motor horsepower shall be adequate so that the pump is non -overloading throughoutthe entire pump performance curve from shut-off through run -out. BEARINGS The pump shaft shall rotate on two bearings. Motor bearings shall be permanently grease lubricated. The upper bearing shall be a single roller bearing. The lower bearing shall be a two row angular contact bearing to compensate for axial thrust and radial forces. Single row lower bearings are not acceptable. MECHANICAL SEAL Each pump shall be provided with a tandem mechanical shaft seal system consisting of two totally independent seal assemblies. The seals shall operate in an lubricant reservoir that hydrodynamically lubricates the lapped seal faces at a constant rate. The lower, primary seal unit, located between the pump and the lubricant chamber, shall contain one stationary and one positively driven rotating tungsten - carbide ring. The upper, secondary seal unit, located between the lubricant chamber and the motor housing, shall contain one stationary tungsten -carbide seal ring and one positively driven rotating tungsten -carbide seal ring. Each seal interface shall be held in contact by its own spring system. The seals shall require neither maintenance nor adjustment nor depend on direction of rotation for sealing. The position of both mechanical seals shall depend on the shaft. Mounting of the lower mechanical seal on the impeller hubwill not be acceptable. For special applications, other seal face materials shall be available. The following seal types shall not be considered acceptable nor equal to the dual independent seal specified: shaft seals without positively driven rotating members, or conventional double mechanical seals containing either a common single or double spring acting between the upper and lower seal faces. Cartridge type systems will not be acceptable. No system requiring a pressure differential to offset pressure and to effect sealing shall be used. Each pump shall be provided with an lubricant chamber for the shaft sealing system. The lubricant chamber shall be designed to prevent overfilling and to provide lubricant expansion capacity. The drain and inspection plug, with positive anti -leak seal shall be easily accessible from the outside. The seal system shall not rely upon the pumped media for lubrication. The motor shall be able to operate dry without damage while pumping under load. Seal lubricant shall be FDA Approved, nontoxic. PUMP SHAFT Pump and motor shaft shall be the same unit. The pump shaft is an extension of the motor shaft. Couplings shall not be acceptable. The shaft shall be AISI type 431 stainless steel. If a shaft material of lower quality than 431 stainless steel is used, a shaft sleeve of 431 stainless steel is used to protect the shaft material. However, shaft sleeves only protect the shaft around the lower mechanical seal. No protection is provided in the oil housing and above.

The estimated flow for the facility is 15,000 gallons/day (gpd). This evaluation was performed by making auger borings to sufficient depths to determine any soil limitations and to identify the soil to the series level. The soil boundaries were flagged in the field, and have been located by Global Positioning System (GPS) technology for spatial reference. Usable soils on the property are most like the Cecil (Clayey, kaolinitic, thermic Typic Hapludults) and Pacolet (Clayey, kaolinitic, thermic Typic Kanhapludults) soil series. The Cecil and Pacolet soils are typically very deep and well drained. Both soil series have a moderate permeability. The depth to bedrock is typically greater than 6 feet. A properly designed, constructed and maintained, slow rate spray irrigation system can adequately serve as a wastewater treatment alternative. The major limitation of these soils is their permeability. Nutrient factors such as nitrogen, phosphorus, organic matter, etc. are not typically limiting factors in the design of spray systems treating domestic wastewater. Nutrient calculations, if needed, will be addressed in a separate Agronomist's report. Unusable areas either contain depressional topography or the slopes are too steep. Site disturbances on the spray field itself should be minimized and a permanent vegetative cover should be established and/or maintained. Effluent should not be applied at an instantaneous rate exceeding 0.4" /hr. During this site visit, S&EC also evaluated the hydraulic characteristics of the soils on the property. The purpose of this evaluation was to determine the hydraulic conductivity of the unsaturated zone so that this data could be used to determine potential loading rates for an on -site surface wastewater treatment system. The system is expected to receive 15,000 gallons per day (gpd) of sewage effluent. The following is a brief report of the methods utilized in this evaluation and the results obtained. Wetland Delineation/Permitting/Mitigation Soil/Site Evaluations for On -Site Septic Systems Environmental Assessments/Audits Home Office: 11010 Raven Ridge Road ■ Raleigh, North Carolina 27614 ■ Phone: (919) 846-5900 ■ Fax: (919) 846-9467 A water budget was developed for the proposed irrigation field balancing water losses and gains using average and above average precipitation: Evapotranspiration + Natural Runoff + Drainage = Precipitation and Irrigation 3. Data Inputs A. Potential Evapotranspiration (PET) Potential Evapotranspiration data were obtained from the North Carolina State University Experiment Station, Bulletin 396, `Weather and Climate in North Carolina." Values of PET do not vary significantly over North Carolina, so data for Raleigh was used. B. Drainage (DR) The drainage term was calculated by the procedure described in US EPA 625/R- 92-005, "Wastewater Treatment and Disposal for Small Communities." The percolation or drainage rate is typically calculated as 1 to 10% of the permeability of the most restrictive horizon in the soil. For this soil, the most restrictive horizon is the Bt horizon. The Ksat data of this horizon was had an average K of 0.165 in/hr. This is in the moderate hydraulic conductivity class (0.14-1.4 in/hr). If approximately 3% of the 0.165 in/hr conductivity were utilized, then the drainage rate would be 0.005 in/hr, or 0.12 in/day. Input for this figure is based on 31, 30, and 28 days per month. C. Natural Runoff (NR) Since the system is designed to operate with no runoff and to be conservative, the rate of natural runoff was not used in the water balance calculations. D. Precipitation Average monthly precipitation rates for Statesville, NC were utilized. The data was obtained from the North Carolina State University Experiment Station, Bulletin 396, `NVeather and Climate in North Carolina." These values are shown on the attached water balance. We utilized an average yearly rainfall total of 46.47 inches to determine average application rates and to determine maximum cumulative storage requirements. The water balance application rates are assumed to be maximum average rates. Specifications: Assumed Design flow—15,000 gal/day Allowable Irrigation Rate - 0.051 gpd/fl (0.58 in/week) Soil Descrivtions Soil auger borings were made to identify soil textures and to determine if restrictive horizons occur on the site. Borings were performed at the locations shown on the attached Map. A soil profile description is attached in Table I of this report for several of the locations (Site 1, Site 2, and Site 3). Hvdraulic Conductivity (Unsaturated Zone Unsaturated Zone: Saturated hydraulic conductivity of the unsaturated zone was measured using a constant head permeameter. The methods used in these measurements were similar to those described in Methods of Soil Analysis, Part 1., Chapter 29 — Hydraulic Conductivity of Saturated Soils: Field Methods, 29 — 3.2 Shallow Well Pump In Method, pp. 758-763 and in the Soil Science Society of America Journal, Vol. 53, no. 5, Sept. — Oct. 1989, "A Constant -head Permeameter for Measuring Saturated Hydraulic Conductivity of the Vadose Zone" and "comparison of the Glover Solution with the Simultaneous — Equations Approach for Measuring Hydraulic Conductivity." The Ksats of the A, B, BC, and C-horizons were measured in the usable soil areas and the results are shown in Table 2. One saturated hydraulic conductivity (Ksat) measurement was made in the A horizon at a depth of 8" below ground surface, and was 8.3 gpd/ft. The depths of Ksat in the Bt horizon was between 13 and 24 inches at three sites (site 1, site 2, and site 3). These Ksats ranged between 1.53 and 13.42 gpd/ft , with an average of 7.23 gpd/fl . Ifthe two highest values are dropped, the average is 2.47 gpd/ft . The Ksat of the BC horizon was measured between the depths of 55 and 82 inches at the same locations listed above. These Ksats ranged between 3.65 and 4.53 gpd/ft , with an average of 4.08 gpd/ft. One Ksat for the C-horizon was measured between the depths of 83 and 92 inches at site 1. The measurement was 14.83 gpd/fl Calculation for Allowable Irrigation Rite for Suray/Drin Irrigation Systems Maximum Instantaneous Application Rate (m/hr) Utilizing the attached Table 3 for typical ranges of soil infiltration rates the site falls into the sandy loam soils in the 3-90/6 slope range. Therefore 0.4" to O.T'Ihr. would be the maximum instantaneous application rate. We recommend 0.47/hr. if a good vegetative cover is established on -site prior to use. 2. Water Balance (Table 4) Minimum area needed for spray system - 294,118 fl (wetted area) (— 6.75 acre) Maximum Instantaneous Application Rate- 0.4 in/hr Conclusion: Based on the results of this study, a slow rate spray irrigation system designated as per the criterion in this report should function satisfactorily on the site. It is recommended that the soil area onsite be loaded at 0.58 in/wk on average, based on Table 4. The actual system application amount should be based on the water balance enclosed and varied based on actual precipitation and potential evapotranspiration. The total average flow that the site can accept will depend on the actual number of acres to be irrigated. Based on Table 5, the storage requirement is 85 days. This report is conservative since we are assuming 15,000 gpd year round. During the off- season the daily Sow should be much less. At this point the off-season flow has not been confirmed. Since the winter months would be the off-season and this is the time of year when most of the storage is needed, reduced daily application during this period will reduce the storage requirement. Once the preferred cover crop is determined by the owner and engineer, S&EC can if needed prepare an Agronomist's report dealing with establishment and maintenance of the cover crop. If requested to meet on -site, S&EC should be given a minimum of five -days notice for scheduling purposes. If you have any questions or require additional information please call.

A detailed soil/site evaluation of portions of the aforementioned property was performed by S&EC to determine suitability for a proposed new beach. The revised estimated flow for the facility is: for the months from April through September, 15,000 gallons/day (gpd) (1500 persons @ 10 gallons/person/day) and for the months of October through March, 200 gpd (40 persons/day @ 5 gallons/person/day). This evaluation was performed by making auger borings to sufficient depths to determine any soil limitations amid to identify the soil to the series level. The soil boundaries were flagged in the field, and have been located by Global Positioning System (GPS) technology for spatial reference. Usable soils on the property are most like the Cecil (Clayey, kaolinitic, thermic Typic Hapludults) and Pacolet (Clayey, kaolinitic, thermic Typic Kanhapludults) soil series. The Cecil and Pacolet soils are typically very deep and well drained. Both soil series have a moderate permeability. The depth to bedrock is typically greater than 6 feet. A properly designed, constructed and maintained, slow rate spray irrigation system can adequately serve as a wastewater treatment alternative. The major limitation of these soils is their permeability. Nutrient factors such as nitrogen, phosphorus, organic matter, etc. are not typically limiting factors in the design of spray systems treating domestic wastewater. Nutrient calculations, if needed, will be addressed in a separate Agronomist's report. Unusable areas either contain depressional topography or the slopes are too steep. Site disturbances on the spray field itself should be minimized and a permanent vegetative cover should be established and/or maintained. Effluent should not be applied at an instantaneous rate exceeding 0.4"/hr. During this site visit, S&EC also evaluated the hydraulic characteristics of the soils on the property. The purpose of this evaluation was to determine the hydraulic conductivity of the unsaturated zone so that this data could be used to determine potential loading rates for an on -site surface wastewater treatment system_ The system is expected to receive up Wetland Deiineation/Permitting/Mitigation Soil/Site Evaluations for On -Site septic Svstems Environmental Assessments/Audits Home Office: 11010 Ravcn Ridge Road ■ Raleigh, North Carolina 27614 ■ Phone: (919) 346-5900 ■ Par: (919) 846-9467 06/05/2001 13:03 3284667406 SOIL AND ENVIP CONS PAGE 03 to 15,000 gallons per day (gpd) of sewage effluent. The following is a brief report of the methods utilized in this evaluation and the results obtained. Soil Descriptions Soil auger borings were made to identify soil textures and to determine if restrictive horizons occur on the site. Borings were performed at the locations shown on the attached Map. A soil profile description is attached in Fable 1 of this report for several of the locations (Site 1, Site 2, and Site 3). aulic Conductive Unsatur ted Zone Unsaturated Zone: Saturated hydraulic conductivity of the unsaturated zone was measured using a constant head permeameter. The methods used in these measurements were similar to those described in Methods of Soil Analysis, Part 1., Chapter 29 — Hydraulic Conductivity of Saturated Soils: Field Methods, 29 — 32 Shallow Well pump In Method, pp. 758-763 and in the Soil Science Society of America Journal, Vol. 53, no. 5, Sept. — Oct. 1989, "A Constant -head Permeameter for Measuring Saturated Hydraulic Conductivity of the Vadose Zone" and "comparison of the Glover Solution with the Simultaneous — Equations Approach for Measuring Hydraulic Conductivity." The Ksats of the A, B, BC, and C-horizons were measured in the usable soil areas and the results are shown in Table 2. One saturated hydraulic conductivity (Ksat) measurement was made in the A horizon at a depth of 8" below ground surface, and was 8.3 gpd/ft2. The depths of Ksat in the Bt horizon was between 13 and 24 inches at three sites (site 1, site 2, and site 3)_ These Ksats ranged between 1.53 and 13.42 gpd/ft2, with an average of 7.23 gpd/ft2. If the two highest values are dropped, the average is 2.47 gpd/ft2. The Ksat of the BC horizon was measured between the depths of 55 and 82 inches at the same locations listed above. These Ksats ranged between 3.65 and 4.53 gpd/f ", with an average of 4.08 gpd/ft2. One Ksat for the C-horizon was measured between the depths of 83 and 92 inches at site 1. The measurement was 14.83 gpd/ft2. Calculation for Allowable Irrigation hate for Spray/Drip Irrigation Systems Maximum Instantaneous Application Rate (in/hr) Utilizing the attached Table 3 for typical ranges of soil iaCtration rates the site falls into the sandy loam, soils in the 3-9% slope range. Therefore 0.4" to 0.7"/hr. would be the maximum instantaneous application rate. We recommend 0.4"/hr. if a good vegetative cover is established on -site prior to use. 06/05/2001 13:03 8284667406 SOIL AND ENVIR CONS PAGE 04 2. Water Balance (Table 4) A water budget was developed for the proposed irrigation field balancing water losses and gains using average and above average precipitation_ Evapotranspiration + Natural Runoff + Drainage = Precipitation and Irrigation 3. Data Inputs A.. Potential Evapotranspiration (PET) Potential Evapotranspiration data were obtained from the North Carolina State University Experiment Station, Bulletin 396, "Weather and Climate in North Carolina." Values of PET do not vary significantly over North Carolina, so data for Raleigh was used. B. Drainage (DR) The drainage term was calculated by the procedure described in US EPA 625/R- 92-005, "Wastewater Treatment and Disposal for Small Communities." The percolation or drainage rate is typically calculated as 1 to 10% of the permeability of the most restrictive horizon in the soil. For this soil, the most restrictive horizon is the Bt horizon. The Ksat data of this horizon was .had an average K of 0.165 in/hr. This is iu the moderate hydraulic conductivity class (0.14-1.4 in/hr). If approximately 3% of the 0.165 in/hr conductivity were utilized, then the drainage rate would be 0.005 in/hr, or 0.12 in/day. Input for this figure is based on 31, 30, and 28 days per month. C. Natural Runoff (NR) Since the system is designed to operate with no runoff and to be conservative, the rate of natural runoff was not used in the water balance calculations. D. Precipitation Average monthly precipitation rates for Statesville, NC were utilized. The data was obtained from the North Carolina. State University Experiment Station, Bulletin 396, "Weather and Climate in North Carolina." These values are shown on the attached water balance. We utilized an average yearly rainfall total of 46.47 inches to determine average application rates and to determine maximum cumulative storage requirements. The water balance application rates are assumed to be maximum average rates. 06/05/2001 13:03 323466-1406 SOIL AND EN',.:IR CONS PAGE 05 Specifications: Assumed Design flow: April — September: 183 days x 15,000 gal/day = 2,745,000 gallons October — March: 182 days x 200 gal/day = 3 6 400 ons Total yearly flow: = 2,781,400 gallons Average daily flow: (2,791,4009al / 365 days) = 7,620 gal/day Allowable Irrigation Rate - 0.051 gpolfi" (0.58 in/week) Minimum area needed for spray system - 149,412 ftZ (wetted area) (— 3.43 acre) Maximum Instantaneous Application Rate- 0.4 in/hr Conclusion: Based on the results of this study, a slow rate spray irrigation system designated as per the criterion in this report should function satisfactorily on the site. It is recommended that the soil area onsite be loaded at 0.58 in/wk on average, based on Table 4. The actual system application amount should be based on the water balance enclosed and varied based on actual precipitation and potential evapotranspiration. The total average flow that the site can accept will depend on the actual number of acres to be irrigated. Based on Table 5, the storage requirement is 42 days. If more area is irrigated the storage requirement could be lowered. Once the preferred cover crop is determined by the owner and engineer, S&EC can if needed prepare an Agronomist's report dealing with establishment and maintenance of the cover crop. If requested to meet on -site, S&EC should be given a minimum of five -days notice for scheduling purposes. If you have any questions or require additional information please call.

The results for this analysis are in Table 1 below. Results for organic matter is listed as a total percent in the soil, available nutrients are listed as parts per million (ppm), the Cation Exchange Capacity (CEC) is listed as milliequivalents per 100 gram of soil (meq/100g), and nutrients in the percent base saturation (BS%) are listed as a percent of the total solution.

According to the soil test results, P levels are very low. 1.2 CATION EXCHANGE CAPACITY (CEC), pH, AND PERCENT BASE SATURATION (% BS) The surface soil CEC averaged 4.7 milliequivalents per 100 gram of soil (meq/100g) and is an inherent property of soils that is unlikely to change. Coarse textured soils have an inherently low CEC and their ability of the soil to hold nutrients is low. Consequently there may be a high leaching potential of nutrients through the soil profile. The soil pH 4.7 standard units. This pH value is extermely below average for uptake of nutrients and heavy metals on Pine Trees and Coastal Bermudagrass. The optimal pH should be maintained around 6.0 for Pines and 6.5 for Coastal Bermudagrass. An annual application of an appropriate amount of calcium carbonate should be considered when the pH falls below 5.5. Annual soil sampling is recommended to ensure crop demand of nutrients is meet. The soil percent base saturation (%BS) is the percentage of the soil cation exchange sites that are occupied by basic cations (Mg, Ca, K, and Na). The %BS is an important parameter in relation to soil properties and plant nutrition. When considering those basic cations that are important for plant development, the %BS most often recommended is: Ca (65 - 75%); Mg (10 - 15%); and K (2 - 5%) The average soil %BS was as follows: Ca (60.0)%, Mg (17.7)%, and K (3.3)%. Application of dolomitic limestone is recommended to increase the pH and % BS. 1.3 BASIC CATIONS (Ca, Mg, and K) The Ca and Mg available for plant uptake are 60 ppm (120 lbs./acre) and 24 ppm (48 lbs./acre) respectively. Soil test analyses list Mg and Ca in the very low range. Soil samples should be collected in the summer to evaluate the Ca status and time requirement of the soil. It is recommended that approximately 2201bs. per acre of Phosphate and 60 lbs. per acre of Magnesium be applied as spilt applications. The available K averaged 64 ppm (128.0 lbs./acre). Soil test analyses list K in the medium range. Based on soil test results, K additions are needed for the future uptake by plants. Potash is recommended to increase K to suitable levels. It is recommended that approximately 120 lbs. per acre of potash be applied as spilt applications. 2.0 AGRONOMY REPORT 2.1 SUGGESTED SITE MANAGEMENT PLAN Field 1 is suitable for timber operations or hay production. Based on the preliminary soil scientist report no restrictions were seen on the proposed irrigation field. Buffer requirements for setbacks from, structures that will be for public use, water bodies, wells, and state roads will reduced the useable acreage in this field. Regulatory Agents might stipulate buffers. The useable acreage in Field 1 should be considered prime for use as land application site. Pine trees are documented to be able to uptake approximately 75 pounds of Nitrogen/acre/year. To ensure maximum uptake of nutrients from the bio-solids by the trees, based on the soil analysis, additional fertilizer requirements are suggested. Once biosolid applications begin, the selected crop will grow more rapid, because nutrients and water will not limit crop production. Bermuda Grass and Fescue, as well as other types of forage, are documented to be able to uptake approximately 250 pounds of Nitrogen/acre/year. To ensure maximum uptake of nutrients from the bio-solids by the grass, weed species need to be minimized and based on the soil analysis, additional fertilizer requirements are suggested. Once biosolid applications begin, the selected crop will grow more rapid, because nutrients, weeds and water will not limit crop production. This requires frequent cuttings and removal of hay by the site manager. By using standard agricultural practices for the management of timber and forage the operator should see significant benefits from the application of residuals. In turn, this field should provide good assimilation of the plant available nutrients contained in the residuals and afford an environmentally safe means of nutrient recycling. Considerations are suggested that when an application event occurs the site manager check the depth (to approximately 36 inches of the natural soil surface) of the apparent water table in the field. This is to prevent contamination of the groundwater. 2.2 ADDITIONAL FERTILIZER REQUIREMENTS Annual soil sampling is recommended to ensure that the crop demands of nutrients are meet. Soil tests should be taken annually in the early fall to determine nutrient and micronutrient availability. Soil testing is the most accurate way to determine the rate and grade of fertilizer to apply. Recommended soil analyses are needed for Phosphorus, Potassium, Sodium, pH, CEC, Percent Base Saturation, and Percent Hydrogen. The optimal pH should be maintained at approximately 6.0 for Pine trees and 6.5 for Bermuda grass. An application of 3,300 lbs. of CaCO3 per acre for the Bermuda grass and 2,8001bs. of CaCO3 per acre for the Pine trees is sufficient to increase the pH to the desired level. Also, an annual application of Calcium Carbonate should be considered if the pH falls below 5.5. It is recommended that approximately 220 lbs. per acre of Phosphate, 60 lbs. per acre of Magnesium, and 120 pounds per acre of potash be applied as spilt applications.

C. Norman Jones L Apply temporary protective covering to lower two (2) feet of finished walls adjacent to poured floor slabs and similar conditions, and guard against spattering during placement. i E. General: Comply with ACI-304 "Recommended Practice for Measuring, Mixing, Transporting, and Placing Concrete," and as herein specified. C. Deposit concrete continuously or in layers of such thickness that no concrete will be G placed on concrete which has hardened sufficiently to cause the formation of seams or planes of weakness. If a section cannot be placed continuously, provide construction joints as herein specified. Deposit concrete as nearly as practicable to its final location - to avoid segregation. D. Water shall not be added at the site without permission from Engineer or Engineer's Field Representative. Any water which is added shall be recorded on the delivery ticket and test report. E. Placing Concrete�in Forms: Deposit concrete in forms in horizontal layers not deeper than 24 inches and in a manner such to avoid inclined construction joints. Where placement consists of several layers, place each layer while preceding layer is still - plastic in order to avoid cold joints. Do not drop concrete a vertical distance greater than five (5) feet. To place concrete lifts greater than five (5) feet, use a hose, drop chute, or other approved method. F. Consolidate placed concrete by mechanical vibrating equipment supplemented by hand -spading, rodding, or tamping. Use equipment and procedures for consolidation of concrete in accordance with ACI-309. r G. Do not use vibrators to transport concrete inside forms. Insert and withdraw vibrators j vertically at uniformly -spaced locations not farther than visible effectiveness of the machine. Place vibrators to rapidly penetrate the placed layer and at least six (6) inches into the preceding layer. Do not insert vibrators into lower layers of concrete that have begun to set. At each insertion, limit duration of vibration to the time necessary to consolidate concrete and complete embedment of reinforcement and other embedded items, without causing segregation of mix. H. Placing Concrete Slabs: Deposit and consolidate concrete slabs in a continuous operation, within limits of construction joints, until the placing of a panel or section is completed. I. Consolidate concrete during placing operations so that concrete is thoroughly worked - around reinforcement and other embedded items and into corners. �l 03310-12 Lake Norman State Park 3.15 (duality Control Testing During Construction: A. A testing agency shall be employed by the Contractor to perform tests and submit reports to the Engineer in order to ensure quality control of the installed concrete work. The Contractor will be compensated for the invoiced work completed by the testing agency. This compensation will be deducted from the testing allowance established by the approved schedule of values. E. Sampling and testing for quality control during placement of concrete may include the following, as directed by Engineer. C. Sampling Fresh Concrete: ASTM C 172, except modified for slump to comply with ASTM C 94. 1. Slump: ASTM C 143; one (1) test at point of truck discharge for each day's pour of each type of concrete; additional tests when concrete consistency seems to have changed. 2. Air Content: ASTM C 173 (volumetric method for lightweight or normal weight concrete) or ASTM C 231 (pressure method for normal weight concrete); one (1) for each day's pour of each type of air -entrained concrete. 3. Concrete Temperature: Test hourly when air temperature is 40 degrees Fahrenheit (four (4) degrees Celsius) and below and when 80 degrees Fahrenheit (27 degrees Celsius) and above, as well as each time a set of compression test specimens is made. 4. Compression Test Specimen: ASTM C 31; one (1) set of four (4) standard cylinders for each compressive strength test, unless otherwise directed. Mold and store cylinders for laboratory -cured test specimens except when field -cured test specimens are required. 5. CMpressive Strength Tests: ASTM C 39; one (1) set for each day's pour exceeding five (5) cubic yards, plus additional sets for each 50 cubic yards over and above the first 25 cubic yards of each concrete class placed in any one day; one (1) specimen tested at seven (7) days, two (2) specimens tested at 28 days, and one (1) specimen retained in reserve for later testing, if required. 6. When frequency of testing will provide less than five (5) strength tests for a given class of concrete, conduct testing from at least five (5) randomly selected batches or from each batch, if fewer than five (5) are used. D. Test results will be reported in writing to Engineer and Contractor within 24 hours after tests. Reports of compressive strength tests shs11 contain the project identification name and number, date of concrete placement, name of concrete testing Lake Dorman State Park 03310-18 service, concrete type and class, location of concrete batch in structure, design compressive strength at 28 days, concrete mix proportions and materials; compressive breaking strength and type of break for both seven (7)-day and 28-day tests. E. Additional Tests: The testing service will make additional tests of in -place concrete when test results indicate specified concrete strengths and other characteristics have not been attained in the structure, as directed by Engineer. The testing service may conduct tests to determine adequacy of concrete by cored cylinders complying with ASTM C 42, or by other methods as directed. Contractor shall pay for such tests when unacceptable concrete is verified. F. Sub -Standard Concrete: Any concrete furnished under this specification that fails to reach the required design compressive strength after 28 days, as evidenced by the compressive strength test specified herein, shall be considered sub -standard. 1. The procedure specified in ACT-318 for the evaluation and acceptance of concrete shall be used to determine if the sub -standard concrete is to be removed and replaced. Engineer shall make the final decision. Any sub -standard concrete which is removed and replaced shall be done so at Contractor's expense. 2. For sub -standard concrete which is left in place, Contractor shall reimburse Owner with an amount of $0.05 for each pound per square inch that the actual 28-day concrete strength is below the specified compressive strength for each cubic yard of concrete in the pour. The strength of concrete for a particular pour shall be the average of all but the one lowest of the 28-day compression tests for that pour. Said reimbursement shall be deducted from the Contract Amount by change order. END OF SECTION 03310 Lake Norman State Park 03310-19
