a.Equipment. These specifications are based on dowelling by mechanical dowel machines. Alternate methods may be used if the results are equal to those obtained by mecha nical devices that press the tie together, drill and dowel in one or two operation. Dowelling by mechanical means is considered satisfactory as long as sufficient pressure is applied to completely close the split. Substitution of hand drills and pneumatic hammers for drilling dowels in switch ties is satisfactory as long as splits are held closed during dowelling by the use of clamps or other devices.
b.Pre -Drilled Holes. The maximum diameter of the pre -drilled holes is 1/8 inch less than the diameter of dowel. The minimum length of the hole shall be equal to the length of the dowel, except that holes drilled from the face opposite the face where the dowel enters shall be completely through the tie.
c.Location of Dowels. Dowels shall be driven perpe ndicular to the face most parallel to the split. Two dowels shall be used to close each split. They shall be located a minimum of 4 inches and a maximum of 6 inches from the end of the tie. Where the tie is split parallel to the narrow faces, the 7 3/4 inc hes long dowels shall be located 1 1/2 inch plus or minus 1/4 inch

d.Protruding Dowels. Dowels not completely driven by dowelling machines shall be driven flush with the wood with a hammer. Dowels which protrude more than 1/4 inch after driving should be burned off with an oxyacetylene torch. However, dowels bent over flush with the surface of the wood will be accepted, provided this is done without splitting the wood.
2.Irons. Anti-splitting irons are driven into the ends of ties and shall be placed to cross at right angles and the greatest possible number of radial lines of the wood. Irons shall be placed far enough from the wide faces to prevent splitting of the tie.
a.De sign. Anti-splitting irons shall be made from a strip of steel formed to an “S” iron or “C” iron design. They will be of adequate size to prevent splitting of the tie.
b.Material. Irons shall conform to specifications for anti -splitting irons given in the AREA Manual, Chapter 3, Section 1.9.2.1.
3.Nail Plates. Anti-splitting nail plates shall be applied to the ends of the ties.

Preservative treatment shall be carried out in accordance with AWPA Standard C1, All Timber Products - Preservative Treatment by Pressure Processing or C6, Cross Ties and Switch Ties - Preservative Treatment by Pressure Processes. The method used shall be the empty cell process by use of initial air to control retention. Retention of preservative shall be 7 pounds of preservative per cubic foot of wood. Retention shall be determined by gauge in accordance with paragraph 3.1 of AWPA Standard C1. When specified, pentacholorphenol in heavy AWPA Standard P9A solvent may be used as a preservative. Minimum retention shall be 0.4 pounds of preservative per cubic foot of wood. INSPECTION A ND TESTING. The Contractor shall give the Materials Bureau thirty days written notice prior to the start of preservative treatment. This notice shall include at the minimum, the name of the tie treater, the location of the treating plant and that date of the initial treatment.

SECTION 713 - LANDSCAPE DEVELOPMENT MATERIALS
713-01 Topsoil
SCOPE. This specification covers the material requirements for topsoil for use in turf establishment, wildflower seeding, sodding, and planting. MATERIAL REQUIREMENTS. Topsoil may be naturally occurring or may be manufact ured. If naturally occurring topsoil exists on the site it shall be the surface layer of soil at a depth specified in the contract documents or approved by the engineer. Manufactured topsoil is a mixture of materials comprised of a mineral(soil) component that by itself does not exhibit the properties and characteristics of topsoil, an organic material component consisting of compost(s) meeting the requirements of §713 -15 Compost , and amendment(s), such as limestone meeting the requirements of §713 -02 Lime stone that, when combined together, meet the requirements for topsoil. For manufactured topsoil the contractor shall thoroughly mix the organic portion with the granular portion under dry conditions. Topsoil shall be free from refuse, material toxic or oth erwise deleterious to plant growth, subsoil, sod clumps, seeds or other viable propagules of invasive plants, woody vegetation and stumps, roots, brush, refuse, stones, clay lumps, or similar objects. Construction and demolition debris as classified under 6 NYCRR Part 360, other than uncontaminated land clearing debris, shall not be used to manufacture or amend topsoil. Sod and herbaceous growth such as grass and non -invasive weeds need not be removed but shall be thoroughly broken up and mixed with the soi l during handling or manufacturing operations.
A.Topsoil -Reuse of On -Site Materials. Existing topsoil stripped and reclaimed in accordance with Section 203 Excavation and Embankment taken from sites within the contract limits. The general limits and de pth of the material to be utilized for topsoil will be indicated in the Contract documents. Where no depth is indicated it shall be 6 inches.
