(A) All soil and vegetation shall be removed for a depth of six inches below the existing grade line. Any utilities such as meter or valve boxes shall be adjusted in height so that their tops will be flush with the top of the new sidewalk. If possible, obstacles such as power or light poles, fire hydrants, signs, fences, and other municipal, corporate, or private obstacles shall be relocated away from the sidewalk area. Vegetation obstacles such as trees, hedges, and the like shall be trimmed, relocated, or removed to provide adequate clearances. Relocation, removals, adjustments, and trimming shall be performed by authorized representatives of the appropriate owners.
(B) Four-mil polyethylene vapor barrier shall be provided directly under the concrete for the full width and length of the sidewalk. Six-inch by six-inch 10/10 gauge welded wire reinforcement fabric shall be provided at mid-depth of the concrete. The fabric shall be three feet by six inches wide, and shall be lapped six inches at splices. The fabric shall not pass through expansion joints.
(C) Three-quarter-inch-deep transverse control joints shall be tooled at four-foot spacing along the length of the sidewalk. Half-inch bituminous fiber expansion joints shall be provided at 40-foot maximum spacing in lieu of a control joint at that location. Expansion joints shall be full depth of concrete and shall have a half-inch deep bituminuous sealer applied at the top, level with the surface of the sidewalk.
(D) Concrete finishing shall consist of tooling joints and edging both sides of the walk for the entire length, and the surface shall receive two steel trowelings, followed by a stiff broom finish across the width of the sidewalk.
