SECTION 02204

BASE/DRAINAGE GENERAL SPECIFICATIONS

A. GENERAL

Install in accordance with Manufacturer's instructions. The Base Contractor and the Turf Contractor shall strictly adhere to the installation procedures outlined under this section. Any variance from these requirements must be accepted in writing, by the Manufacturer’s on-site representative, and submitted to the Architect/Owner, verifying that the changes do not in any way affect the warranty.

B. SOIL BORINGS AND GEO-SOILS REPORT

The specified artificial grass sports field system requires a permeable and stable base for outdoor use. The site’s overall soil and drainage properties should be tested and reported on by an experienced testing laboratory. The key to a good design starts with test borings at locations throughout the site. A representative number of boring should be made on a grid or pattern suitable to provide pertinent data for interpretation by a soils engineer or geosoils expert. At least ten (10) borings are recommended.

Borings should be analyzed to reveal the following information (depth of each boring to be at least ten feet or to refusal):

(a) Soil classification at various depths.

(b) Moisture content, by layer.

(c) Percolation rate, by layer.

(d) Sieve analysis, by layer.

(e) Standard proctor on sub base layer

(f) Soil unconfined compressive strength at different depths.

The presence of any rock, ledge, water or expansive clay, organic materials and debris should be reported. All topsoil, organic, and non-compacting materials must be removed.

C.

SUB-GRADE PREPARATION AND DESIGN

1. The soil bed or sub-grade must have a minimum slope of 0.5% or more, depending on the soil analysis, from the longitudinal center of the field towards the sidelines.

3. The soil bed or sub-grade must be compacted in both directions to attain the specified compaction rate, which is generally 95% standard, Proctor.

4. The soil bed or sub-grade must be prepared to tolerances of not more than 1/2” from design grade to allow for even drainage.

5. After the existing sub-grade has been properly graded, contoured and sloped as required, it shall be compacted using ten (10) ton vibrating roller, as close as possible to 95% Proctor density.

6. A suitable geo-textile fabric is required to cover the soil bed. The fabric shall material suitable for the application, a porous non-woven polypropylene stabilization fabric (Mirafi 140 NL, or equal). Place over the base aggregate overlapping the seams properly. Depending on the result of the soil analysis, a moisture barrier may be substituted for the permeable geo-textile liner. If a moisture barrier is to be installed, it shall be a minimum 20 mil thick.

D.

INSTALLATION OF PERIMETER COLLECTORS

1. Excavate perimeter drainage collector trenches minimum 20" wide and 20" deep. The trenches should be constructed with a minimum 0.5% slope commencing at the low point of the collection system and extending to the high points. Collection trenches should be void of all debris.

2. The trenches shall be backfilled using premium materials and compacted by hand tamping (or equivalent machinery) to a minimum 95% of the maximum density.

3. The fabric should be placed in the perimeter trench first. The fabric should be separate from the fabric on the field. Overlap field and trench liners at least 18" in the direction of runoff flow.

4. Overlap all seams a minimum of eight inches. When overlapping fabric, lap in direction the runoff flows.

5. Weight down the fabric with ballast to prevent fabric movement by wind.

6. Perimeter Collector Pipe: Place 8-12" O.D corrugated, perforated plastic pipes in the collector trenches. The centerline of the pipe shall coincide with the centerline of the trench. The pipe shall be capable of withstanding the anticipated loading without deformation. Each header should be designed to handle the maximum runoff related to rainfall in that particular locale. Collector headers must be drained to an acceptable, efficient storm sewer, or approved discharge outlet. Pre-manufactured fittings shall be used for all connections into the collector drainage network.

Verify pipe size by a licensed engineer or hydraulics expert to assure conformance with local drainage and runoff requirements.

7. A minimum of 2" clean, drainable crushed stone aggregate shall be placed in the bottom of the collector trenches, on top of the geotextile. The crushed aggregate must be compacted suitably.

8. Place a minimum of 4" clean, crushed aggregate on the sides of the underdrain pipes and headers, and 6" minimum of the aggregate on top of the pipe network. Compact suitably.

E.

INSTALLATION OF THE PREFABRICATED COMPOSITE (FLAT) FIELD DRAIN SYSTEM

1. Install minimum 1"x 12" prefabricated under-drain system in herringbone design as shown on the shop drawings with lines approximately 20' on center and connect to perimeter drains.

2. Install according to the manufacturer’s specifications, 1” x 12” Horizontal Strip Drain (Horizontal Drain) by American Drainage Systems, or equal, prefabricated flat composite under drain lines to perimeter drain lines according the manufacturer's specifications.

3. The Horizontal Strip Drain is a prefabricated, high-flow soil drainage system that offers better draw down of water than pipe while costing around 60% less to install. Strip drains typically consist of a formed polymeric core surrounded by a geo-textile filter fabric. The strip drain filter fabric allows water to pass into the core while restraining soil particles, which might clog the core. The strip drain core allows water to flow to designated drainage exits.

4. The Contractor shall supply all necessary connectors and waterproof tape and is responsible for a proper and secure connection to the collectors.

5. Tape the under drains every 15’ to the fabric using suitable tape.

6. Use due care when applying aggregate not to crush or otherwise damage the strip drains.

F.

TURF SYSTEM STONE GRADATION SPECIFICATIONS

%PASSING

RESTRICTIONS:

To ensure structural stability:

D60/D10 > 5 and 1 < D230 < 3

D10 D60 Fragmentation must be 100%.

To ensure separation of both stones: D85 of finishing stone > 2 D15 of base stone and 3 < D50 of base stone < 6 D50 of finishing stone

To ensure proper drainage: Permeability of base stone > 10 in/hr (7 X 10-3 cm/sec)

Permeability of finishing stone > 10 in/hr (7 X 10-3 cm/sec)

Porosity of both stones > 25%

(Test with stone saturated and compacted to 95% Proctor.)

Depending on the type of rock present in the crushed stone mix, other mechanical characteristics might be necessary for approval.

“Dx” is the size of the sieve (in mm) that lets pass x% of the stone. For example, D60 is the size of the sieve that lets 60% of the stone pass. These sizes, for calculation purposes, may be obtained by interpolation on a semi-log graph of the sieve analysis.

Should the field need to support heavy vehicles, consideration must be given for the load bearing requirements of the base. This information is to be used as a guide only and must be modified to meet local soil conditions and anticipated rainfalls.

G.

INSTALLATION OF THE OPEN GRADE CRUSHED STONE BASE COURSE

1. The crushed base stone must be laid without damaging or disturbing the soil bed, geo-textile liner or membrane, or the underlying flat composite drains. It is very important not to create any depressions in the sub-grade with heavy equipment. The specified stone or aggregate supplied must conform to the recommended specifications, as noted above. The finished crushed stone or aggregate base supplied must be stable and permeable. The stone shall be damp when transported to site and shall be kept damp during installation, to minimize segregation of the materials.

2. If the required compacted depth of the base course exceeds 6”, the base shall be constructed in two or more layers or lifts of approximate equal thickness. Each layer must be compacted in both directions to attain the specified compaction rate. The base course total thickness shall be 4”.

3. The open graded aggregate base course must be sloped 0.5% from the center longitudinal axis towards the sidelines or as specified on the Plans.

4. The grade of the base course shall not vary from the specified grade by more than ½" from design grade.

5. The base course must be compacted in both directions to attain the specified compaction rate, which is generally 95% standard, Proctor.

H.

INSTALLATION OF THE CRUSHED STONE FINISHING LAYER

1. The final lift of aggregate layer should not be more than 2” deep.

2. The final lift material must be sloped 0.5% from the center longitudinal axis towards the sidelines unless otherwise specified.

3. The final grade must be compacted in both directions to attain the specified compaction rate, which is generally 95% standard, Proctor, or as close as possible to the satisfaction of the Engineer/Architect.

3. The final grade of the finishing stone shall not vary from the specified grade by more than 1/4” from design grade, nor by more than ¼" when measured under a 10 ft straightedge, in all directions. Laser guided fine grading is mandatory. This tolerance is required over the entire field. Check the tolerance-to-grade by means of an orbital laser once the stone is fine graded and compacted to proper density. The turf installation company shall not commence work until the base has been tested for compaction, tolerance to grade, and porosity.

PART 3 EXECUTION

3.1 CONSERVATION OF TOPSOIL: Where indicated, topsoil shall be removed to a depth of 3 inches without contamination with subsoil and stockpiled convenient to areas for later application or at locations specified. Topsoil shall be removed to full depth and shall be stored separate from other excavated materials and piled free of roots, stones, and other undesirable materials. Any surplus of topsoil from excavations and grading shall be stockpiled in locations as directed by the COR. The Contractor shall be responsible for the loading and hauling costs for moving excess topsoil.

3.2 EXCAVATION: After topsoil removal has been completed, excavation of every description, regardless of material encountered, within the grading limits of the project shall be performed to the lines and grades indicated. Satisfactory excavation material shall be transported to and placed in fill areas within the limits of the work. All unsatisfactory material including any soil which is disturbed by the Contractor's operations or softened due to exposure to the elements and water and surplus material shall be removed from the site and disposed of in areas approved for surplus material storage. In the event that it is necessary to remove unsatisfactory material to a depth greater than specified, the Contracting Officer shall be notified and an adjustment in the contract price will be considered in accordance with the contract. Excavations carried below the depths indicated, without specific directions, shall, except as otherwise specified, be refilled to the proper grade with satisfactory material as directed. All additional work of this nature shall be at the Contractor's expense. Excavation and filling shall be performed in a manner and sequence that will provide drainage at all times. Excavations shall be kept free from water while construction therein is in progress. Material required for fills in excess of that produced by excavation within the grading limits shall be obtained from borrow areas.

3.3 DITCHES, GUTTERS, AND CHANNEL CHANGES: Ditches, gutters, and channel changes shall be cut accurately to the cross sections and grades indicated. All roots, stumps, rock, and foreign matter in the sides and bottom of ditches, gutters, and channel changes shall be trimmed and dressed or removed to conform to the slope, grade, and shape of the section indicated. Care shall be taken not to excavate ditches and gutters below the grades indicated. Excessive ditch and gutter excavation shall be backfilled to grade either with satisfactory, thoroughly compacted material or with suitable stone or cobble to form an adequate gutter paving as directed. All ditches and gutters excavated under this section shall be maintained until final acceptance of the work. Satisfactory material excavated from ditches and channel changes shall be placed in fill areas. Unsatisfactory and excess excavated material shall be disposed of. No excavated material shall be deposited closer to the edges of the ditches than indicated and in no case less than 3 feet.

3.4 BACKFILL ADJACENT TO STRUCTURES: Backfill adjacent to structures shall be placed and compacted uniformly in such manner as to prevent wedging action or eccentric loading upon or against the structures. Slopes bounding or within areas to be backfilled shall be stepped or serrated to prevent sliding of the fill. During backfilling operations and in the formation of embankments, equipment that will overload the structure in passing over and compacting these fills shall not be used. Backfill for storm drains and subdrains, including the bedding and backfill for structures other than culverts and drains, shall conform to the additional requirements in other applicable sections.

3.5 PREPARATION OF GROUND SURFACE FOR FILL: All vegetation, such as roots, brush, heavy sods, heavy growth of grass, and all decayed vegetable matter, rubbish, and other unsatisfactory material within the area upon which fill is to be placed, shall be stripped or otherwise removed before the fill is started. In no case will unsatisfactory material remain in or under the fill area. Sloped ground surfaces steeper than one vertical to four horizontal on which fill is to be placed shall be plowed, stepped, or broken up, as directed, in such manner that the fill material will bond with the existing surface. Prepared surfaces on which compacted fill is to be placed shall be wetted or dried as may be required to obtain the specified moisture content and density.

3.6 FILLS AND EMBANKMENTS: Fills and embankments shall be constructed at the locations and to lines and grades indicated. The completed fill shall conform to the shape of the typical sections indicated or shall meet the requirements of the particular case. Satisfactory material obtained during excavation may be used in forming required fill. Fill shall be satisfactory material and shall be reasonably free from roots, other organic material, and trash and from stones having a maximum diameter greater than 6 inches. No frozen material will be permitted in the fill. Stones having a dimension greater than 4 inches shall not be permitted in the upper 6 inches of fill or embankment. The material shall be placed in successive horizontal layers of 12 inches in loose depth for the full width of the cross section and shall be compacted as specified. Each layer shall be compacted before the over‑laying lift is placed. Moisture content of the fill or backfill material shall be adjusted by wetting or aerating, as required, to within plus or minus 5 percent of optimum moisture content as determined from laboratory tests specified in paragraph "DEFINITIONS."

3.7 COMPACTION: Except for slab areas, each layer of the fill or embankment shall be compacted to at least 90 percent of laboratory maximum density. Areas for slabs and other areas indicated as requiring compaction suitable for paved areas shall be compacted to at least the percentage of laboratory maximum density shown in the following tabulation for specific ranges of depth below the surface of the pavement:
