Satisfactory materials for grading comprise stones less than 8 inches, except for fill material for pavements and railroads which comprise stones less than 3 inches in any dimension. 1.2.2 Unsatisfactory Materials Materials which do not comply with the requirements for satisfactory materials are unsatisfactory. Unsatisfactory materials also include man-made fills; trash; refuse; backfills from previous construction; and material classified as satisfactory which contains root and other organic matter or frozen material. Notify the Contracting Officer when encountering any contaminated materials. 1.2.3 Cohesionless and Cohesive Materials Cohesionless materials include materials classified in ASTM D2487 as GW, GP, SW, and SP. Cohesive materials include materials classified as GC, SC, ML, CL, MH, and CH. Materials classified as GM and SM will be identified as cohesionless only when the fines are nonelastic. Perform testing, required for classifying materials, in accordance with ASTM D4318, ASTM C136/C136M and ASTM D1140. 1.2.4 Degree of Compaction Degree of compaction required, except as noted in the second sentence, is expressed as a percentage of the maximum density obtained by the test procedure presented in ASTM D1557 abbreviated as a percent of laboratory maximum density. Since ASTM D1557 applies only to soils that have 30 percent or less by weight of their particles retained on the 3/4 inch SECTION 31 00 00 Page 5 SOF Battalion Administration Facility Fort Bragg, North Carolina PN63850 W912PM-18-C-0015 sieve, express the degree of compaction for material having more than 30 percent by weight of their particles retained on the 3/4 inch sieve as a percentage of the maximum density in accordance with AASHTO T 180 and corrected with AASHTO T 224. To maintain the same percentage of coarse material, use the "remove and replace" procedure as described in NOTE 8 of Paragraph 7.2 in AASHTO T 180. 1.2.5 Topsoil Material suitable for topsoils obtained from offsite areas excavations is defined as: Natural, friable soil representative of productive, well -drained soils in the area, free of subsoil, stumps, rocks larger than one inch diameter, brush, weeds, toxic substances, and other material detrimental to plant growth. Amend topsoil pH range to obtain a pH of 5.5 to 7. 1.2.6 Hard/Unyielding Materials Hard/Unyielding materials comprise weathered rock, dense consolidated deposits, or conglomerate materials which are not included in the definition of "rock" with stones greater than 3 inch in any dimension or as defined by the pipe manufacturer, whichever is smaller. These materials usually require the use of heavy excavation equipment, ripper teeth, or jack hammers for removal. 1.2.7 Rock Solid homogeneous interlocking crystalline material with firmly cemented, laminated, or foliated masses or conglomerate deposits, neither of which can be removed without systematic drilling and blasting, drilling and the use of expansion jacks or feather wedges, or the use of backhoe-mounted pneumatic hole punchers or rock breakers; also large boulders, buried masonry, or concrete other than pavement exceeding 1/2 cubic yard in volume. Removal of hard material will not be considered rock excavation because of intermittent drilling and blasting that is performed merely to increase production. 1.2.8 Unstable Material Unstable materials are too wet to properly support the utility pipe, conduit, or appurtenant structure. 1.2.9 Select Granular Material 1.2.9.1 General Requirements Select granular material consist of materials classified as GW, GP, SW, SP, by ASTM D2487 where indicated. The liquid limit of such material must not exceed 35 percent when tested in accordance with ASTM D4318. The plasticity index must not be greater than 12 percent when tested in accordance with ASTM D4318, and not more than 35 percent by weight may be finer than No. 200 sieve when tested in accordance with ASTM D1140. 1.2.10 Initial Backfill Material Initial backfill consists of select granular material or satisfactory materials free from rocks 1 inches or larger in any dimension or free from rocks of such size as recommended by the pipe manufacturer, whichever is smaller. When the pipe is coated or wrapped for corrosion protection, free SECTION 31 00 00 Page 6 SOF Battalion Administration Facility Fort Bragg, North Carolina PN63850 W912PM-18-C-0015 the initial backfill material of stones larger than 1 inches in any dimension or as recommended by the pipe manufacturer, whichever is smaller. 1.2.11 Expansive Soils Expansive soils are defined as soils that have a plasticity index equal to or greater than 12 when tested in accordance with ASTM D4318. 1.2.12 Nonfrost Susceptible (NFS) Material Nonfrost susceptible material are a uniformly graded washed sand with a maximum particle size of .5 inch and less than 5 percent passing the No. 200 size sieve, and with not more than 3 percent by weight finer than 0.02 mm grain size. 1.2.13 Pile Supported Structure As used herein, a structure where both the foundation and floor slab are pile supported. 1.3 SYSTEM DESCRIPTION Subsurface soil boring logs are appended to the SPECIAL CONTRACT REQUIREMENTS. The subsoil investigation report is attached as an Exhibit to these specifications. These data represent the best subsurface information available; however, variations may exist in the subsurface between boring locations. 1.3.1 Classification of Excavation No consideration will be given to the nature of the materials, and all excavation will be designated as unclassified excavation. 1.3.1.1 Common Excavation Include common excavation with the satisfactory removal and disposal of all materials not classified as rock excavation. 1.3.1.2 Rock Excavation Submit notification of encountering rock in the project. Include rock excavation with blasting, excavating, grading, disposing of material classified as rock, and the satisfactory removal and disposal of boulders 1/2 cubic yard or more in volume; solid rock; rock material that is in ledges, bedded deposits, and unstratified masses, which cannot be removed without systematic drilling and blasting; firmly cemented conglomerate deposits possessing the characteristics of solid rock impossible to remove without systematic drilling and blasting; and hard materials (see Definitions). Include the removal of any concrete or masonry structures, except pavements, exceeding 1/2 cubic yard in volume that may be encountered in the work in this classification. If at any time during excavation, including excavation from borrow areas, the Contractor encounters material that may be classified as rock excavation, uncover such material and notify the Contracting Officer.

SECTION 31 31 16.13 Page 5 SOF Battalion Administration Facility PN63850 Fort Bragg, North Carolina W912PM-18-C-0015 PART 2 PRODUCTS 2.1 SYSTEM DESCRIPTION Chemical termite control uses liquid termiticide treatments applied to the soil to form a continuous chemical barrier in the soil around both sides of the foundation. The application can be surface applied or rodded and trenched. This barrier prevents foraging termites from reaching the foundation and piers. Only the soil adjacent to these foundation elements is treated. For slab construction (including foundations, patios and garages), the entire soil (or gravel) surface is treated before the vapor barrier is installed and the slab poured over it. Soil treatment is coordinated with all building activities from foundation construction through final grading of the soil around the building's exterior. In order for the treatment to be effective, the final phase of the application must be done after final grading and sometimes after landscaping is completed so that the treated soil is not disturbed. 2.2 MATERIALS 2.2.1 Termiticides Provide termiticides currently registered by the EPA or approved for such use by the appropriate agency of the host county and as approved by the Contracting Officer. Select non -repellant termiticides for maximum effectiveness and duration after application. Select a termiticide that is suitable for the soil and climatic conditions at the project site and apply at the highest labeled rate. Submit manufacturer's label and Safety Data Sheet (SDS) for termiticides proposed for use. PART 3 EXECUTION 3.1 PREPARATION Eliminate food sources by removing debris from clearing and grubbing and post construction wood scraps such as ground stakes, form boards, and scrap lumber from the site, before termiticide application begins. 3.1.1 Verification Before work starts, verify that final grades are as indicated and smooth grading has been completed in accordance with Section 31 00 00 EARTHWORK. Finely grade soil and remove particles larger than 1 inch. Compact soil particles to eliminate soil movement. 3.1.2 Foundation Exterior If the exterior perimeter treatment is applied when the horizontal barrier is applied it will be damaged or removed before construction is completed. The exterior foundation perimeter treatment will have to occur in phases when any pads, porches, aprons, sidewalks, final grading or landscape planting are simultaneously involved adjacent to the building foundation. This treatment area should be coordinated after all major construction but before any pads, porches, or other items requiring special consideration are poured adjacent to the foundation walls. Submit written verification that final grading, landscape planting and other items adjacent to the foundation will not disturb treatment of the soil on the exterior sides of foundation walls, grade beams, and similar structures.

Submit certified copies of test results for approval not less than 30 days before material is required for the work. 2.3.2 Approval of Material Tentative approval of material will be based on initial test results. PART 3 EXECUTION 3.1 GENERAL REQUIREMENTS When the ABC is constructed in more than one layer, clean the previously constructed layer of loose and foreign matter by sweeping with power sweepers or power brooms, except that hand brooms may be used in areas where power cleaning is not practicable. Provide adequate drainage during the entire period of construction to prevent water from collecting or standing on the working area. 3.2 STOCKPILING MATERIAL Clear and level storage sites prior to stockpiling of material. Stockpile all materials, including approved material available from excavation and grading, in the manner and at the locations designated. Stockpile aggregates on the cleared and leveled areas designated by the Contracting Officer to prevent segregation. Stockpile materials obtained from different sources separately. SECTION 32 11 23 Page 9 SOF Battalion Administration Facility PN63850 Fort Bragg, North Carolina W912PM-18-C-0015 3.3 PREPARATION OF UNDERLYING COURSE OR SUBGRADE Clean the underlying course or subgrade of all foreign substances prior to constructing the base course(s). Do not construct base course(s) on underlying course or subgrade that is frozen. Construct the surface of the underlying course or subgrade to meet specified compaction and surface tolerances. Correct ruts or soft yielding spots in the underlying courses, areas having inadequate compaction, and deviations of the surface from the specified requirements set forth herein by loosening and removing soft or unsatisfactory material and adding approved material, reshaping to line and grade, and recompacting to specified density requirements. For cohesionless underlying courses or subgrades containing sands or gravels, as defined in ASTM D2487, stabilize the surface prior to placement of the base course(s). Stabilize by mixing ABC into the underlying course and compacting by approved methods. Consider the stabilized material as part of the underlying course and meet all requirements of the underlying course. Do not allow traffic or other operations to disturb the finished underlying course and maintain in a satisfactory condition until the base course is placed. 3.4 GRADE CONTROL Provide a finished and completed base course conforming to the lines, grades, and cross sections shown. Place line and grade stakes as necessary for control. 3.5 LAYER THICKNESS Compact the completed base course to the thickness indicated. No individual layer may be thicker than 6 inches nor be thinner than 3 inches in compacted thickness. Compact the base course(s) to a total thickness that is within 1/2 inch of the thickness indicated. Where the measured thickness is more than 1/2 inch deficient, correct such areas by scarifying, adding new material of proper gradation, reblading, and recompacting as directed. Where the measured thickness is more than 1/2 inch thicker than indicated, the course will be considered as conforming to the specified thickness requirements. The average job thickness will be the average of all thickness measurements taken for the job and must be within 1/4 inch of the thickness indicated. Measure the total thickness of the base course at intervals of one measurement for each 500 square yards of base course. Measure total thickness using 3 inch diameter test holes penetrating the base course. 3.6 COMPACTION Compact each layer of the base course, as specified, with approved compaction equipment. Maintain water content during the compaction procedure to within plus or minus 2 percent of the optimum water content determined from laboratory tests as specified in this Section. Begin rolling at the outside edge of the surface and proceed to the center, overlapping on successive trips at least one-half the width of the roller. Slightly vary the length of alternate trips of the roller. Adjust speed of the roller as needed so that displacement of the aggregate does not occur. Compact mixture with hand -operated power tampers in all places not accessible to the rollers. Continue compaction until each layer is compacted through the full depth to at least 100 percent of laboratory maximum density. Make such adjustments in compacting or finishing procedures as may be directed by the Contracting Officer to obtain true grades, to minimize segregation and degradation, to reduce or increase SECTION 32 11 23 Page 10 SOF Battalion Administration Facility Fort Bragg, North Carolina PN63850 W912PM-18-C-0015 water content, and to ensure a satisfactory base course. Remove any materials found to be unsatisfactory and replace with satisfactory material or rework, as directed, to meet the requirements of this specification. 3.7 PROOF ROLLING In addition to the compaction specified, proof roll areas designated on the drawings by application of as required coverages of a heavy pneumatic -tired roller having four or more tires abreast, each tire loaded to a minimum of 30,000 pounds and inflated to a minimum of 125 psi. A coverage is defined as the application of one tire print over the designated area. In the areas designated, apply proof rolling to the top of the underlying material on which the base course is laid and to the top of the completed base course. Maintain water content of the underlying material and each layer of the base course as specified in Paragraph COMPACTION from start of compaction to completion of proof rolling of that layer. Remove any base course materials or any underlying materials that produce unsatisfactory results by proof rolling and replace with satisfactory materials. Then recompact and proof roll to meet these specifications. 3.8 EDGES OF BASE COURSE Place the base course(s) so that the completed section will be a minimum of 2 feet wider, on all sides, than the next layer that will be placed above it. Place approved material along the outer edges of the base course in sufficient quantity to compact to the thickness of the course being constructed. When the course is being constructed in two or more layers, simultaneously roll and compact at least a 2 foot width of this shoulder material with the rolling and compacting of each layer of the base course, as directed. 3.9 FINISHING Finish the surface of the top layer of base course after final compaction and proof rolling by cutting any overbuild to grade and rolling with a steel -wheeled roller. Do not add thin layers of material to the top layer of base course to meet grade. If the elevation of the top layer of base course is 1/2 inch or more below grade, scarify the top layer to a depth of at least 3 inches and blend new material in and compact and proof roll to bring to grade. Make adjustments to rolling and finishing procedures as directed by the Contracting Officer to minimize segregation and degradation, obtain grades, maintain moisture content, and insure an acceptable base course. Should the surface become rough, corrugated, uneven in texture, or traffic marked prior to completion, scarify the unsatisfactory portion and rework and recompact it or replace as directed. 3.10 SMOOTHNESS TEST Construct the top layer so that the surface shows no deviations in excess of 3/8 inch when tested with a 12 foot straightedge. Take measurements in successive positions parallel to the centerline of the area to be paved. Also take measurements perpendicular to the centerline at 50 foot intervals. Correct deviations exceeding this amount by removing material and replacing with new material, or by reworking existing material and compacting it to meet these specifications. SECTION 32 11 23 Page 11 SOF Battalion Administration Facility PN63850 Fort Bragg, North Carolina W912PM-18-C-0015 3.11 FIELD QUALITY CONTROL 3.11.1 In -Place Tests Perform each of the following tests on samples taken from the placed and compacted ABC . Take samples and test at the rates indicated. a. Perform density tests on every lift of material placed and at a frequency of one set of tests for every 250 square yards, or portion thereof, of completed area. b. Perform sieve analysis including 0.02 mm size material on every lift of material placed and at a frequency of one sieve analysis for every 500 square yards, or portion thereof, of material placed. C. Perform liquid limit and plasticity index tests at the same frequency as the sieve analysis. d. Measure the thickness of the base course at intervals providing at least one measurement for each 500 square yards of base course or part thereof. Measure the thickness using test holes, at least 3 inch in diameter through the base course. 3.11.2 Approval of Material Final approval of the materials will be based on tests for gradation, liquid limit, and plasticity index performed on samples taken from the completed and fully compacted course(s). 3.12 TRAFFIC Completed portions of the base course may be opened to limited traffic, provided there is no marring or distorting of the surface by the traffic. Do not allow heavy equipment on the completed base course except when necessary for construction. When it is necessary for heavy equipment to travel on the completed base course, protect the area against marring or damage to the completed work. 3.13 MAINTENANCE Maintain the base course in a satisfactory condition until the full pavement section is completed and accepted. Immediately repair any defects and repeat repairs as often as necessary to keep the area intact. Retest any base course that was not paved over prior to the onset of winter to verify that it still complies with the requirements of this specification. Rework or replace any area of base course that is damaged as necessary to comply with this specification. 3.14 DISPOSAL OF UNSATISFACTORY MATERIALS Dispose of any unsuitable materials that have been removed outside the limits of Government -controlled land . No additional payments will be made for materials that have to be replaced. -- End of Section -- SECTION 32 11 23 Page 12 SOF Battalion Administration Facility Fort Bragg, North Carolina SECTION TABLE OF CONTENTS DIVISION 32 - EXTERIOR IMPROVEMENTS SECTION 32 92 19 SEEDING 08/17 seeding PART 1 GENERAL 1.1 REFERENCES 1.2 DEFINITIONS 1.2.1 Stand of Turf 1.3 RELATED REQUIREMENTS 1.4 SUBMITTALS 1.5 DELIVERY, STORAGE, AND HANDLING 1.5.1 Delivery 1.5.1.1 Seed Protection 1.5.1.2 Fertilizer Delivery 1.5.2 Storage 1.5.2.1 Seed, and Fertilizer Storage 1.5.2.2 Topsoil 1.5.2.3 Handling 1.6 TIME RESTRICTIONS AND PLANTING CONDITIONS 1.6.1 Restrictions 1.7 TIME LIMITATIONS 1.7.1 Seed PART 2 PRODUCTS 2.1 SEED 2.1.1 Classification 2.1.2 Planting Dates 2.1.3 Seed Purity 2.1.4 Seed Mixture by Weight 2.2 TOPSOIL 2.2.1 On -Site Topsoil 2.2.2 Off -Site Topsoil 2.2.3 Composition 2.3 SOIL CONDITIONERS 2.3.1 Lime 2.3.2 Aluminum Sulfate 2.3.3 Sulfur 2.3.4 Iron 2.3.5 Peat 2.3.6 Sand 2.3.7 Perlite 2.3.8 Composted Derivatives 2.3.8.1 Particle Size 2.3.8.2 Nitrogen Content 2.3.9 Gypsum PN63850 W912PM-18-C-0015 SECTION 32 92 19 Page 1 SOF Battalion Administration Facility Fort Bragg, North Carolina 2.3.10 Calcined Clay 2.4 FERTILIZER 2.4.1 Granular Fertilizer 2.4.2 Hydroseeding Fertilizer 2.5 MULCH 2.5.1 Straw 2.5.2 Hay 2.5.3 Wood Cellulose Fiber Mulch 2.6 WATER 2.7 EROSION CONTROL MATERIALS 2.7.1 Erosion Control Blanket 2.7.2 Erosion Control Fabric 2.7.3 Erosion Control Net 2.7.4 Hydrophilic Colloids 2.7.5 Erosion Control Material Anchors PART 3 EXECUTION 3.1 PREPARATION 3.1.1 EXTENT OF WORK 3.1.1.1 Topsoil 3.1.1.2 Soil Conditioner Application Rates 3.1.1.3 Fertilizer Application Rates 3.2 SEEDING 3.2.1 Seed Application Seasons and Conditions 3.2.2 Seed Application Method 3.2.2.1 Broadcast and Drop Seeding 3.2.3 Mulching 3.2.3.1 Hay or Straw Mulch 3.2.3.2 Mechanical Anchor 3.2.3.3 Asphalt Adhesive Tackifier 3.2.3.4 Non -Asphaltic Tackifier 3.2.3.5 Asphalt Adhesive Coated Mulch 3.2.4 Rolling 3.2.5 Erosion Control Material 3.2.6 Watering 3.3 PROTECTION OF TURF AREAS 3.4 RENOVATION OF EXISTING TURF AREA 3.4.1 Overseeding 3.5 RESTORATION -- End of Section Table of Contents -- PN63850 W912PM-18-C-0015 SECTION 32 92 19 Page 2 SOF Battalion Administration Facility PN63850 Fort Bragg, North Carolina W912PM-18-C-0015 SECTION 32 92 19 SEEDING 08/17 PART 1 GENERAL 1.1 REFERENCES The publications listed below form a part of this specification to the extent referenced.
