4.4 Sidewalk Repairs
A temporary sidewalk closure while a sidewalk repair is underway.
Upon completion of work, sidewalks must be restored according to Highway
Rules, Section 2-09(f)(4) and NYC DOT Standard Highway Specifications. Some of the requirements include but are not limited to:
Expansion Joints— Expansion joints must be placed at 20-foot
intervals, expansion joint filler material must be placed to the full depth of the
sidewalk, and all expansion joints must be recessed and sealed.
Concrete—must be poured and finished in accordance with NYC
DOT Standard Highway Specifications at http://www.nyc.gov/html/dot/downloads/pdf/standard%20_highway_specs_vol%201.pdf.
Sidewalk flags—Must be 5'x 5' where feasibleAll flags containing
substantial defects as defined in the Highway Rules must be replaced; patching of
individual flags is not permitted.
Foundation Material—When replacing a concrete sidewalk, the
foundation material may be retained and graded to the required subgrade. Any foundation
material not meeting specifications must be removed.
Sidewalk Grades—Unless granted a waiver from NYC DOT, permanent
sidewalks must be laid to the legal curb grades.
Transverse Slope—Sidewalks must be laid to pitch from the
building line toward the curb. The minimum slope, calculated on a line perpendicular
to the curb, must be 1" in 5', and the maximum is limited to 3" in 5'. Minimum slopes
should be used wherever possible. The maximum transverse slope permitted for vault
covers, gratings and other sidewalk structures is 1" in 5'.
Longitudinal Slope—The longitudinal slope of the sidewalk
must be uniform and parallel to the curb at the curb's proper grade.
Workers pour cement during sidewalk reconstruction.
Corner Treatment—The two slope lines meeting at the intersection
of the two building lines must drop from a common point at the building corner toward
their respective curbs at a rate within the limits prescribed in the Highway Rules.
If this is not possible, sketches or drawings must be submitted, in duplicate, showing
the proposed method of treatment to NYC DOT for approval.
Pedestrian Ramps—When a corner is constructed, reconstructed
or repaired, pedestrian ramps must be installed in accordance with NYC DOT Standard
Highway Specifications found at http://www.nyc.gov/html/dot/downloads/pdf/standard%20_highway_specs_vol%201.pdf and in accordance with the most recent revision of Drawing H-1011 from the NYC
DOT's Standard Details of Construction at http://www.nyc.gov/html/dot/downloads/pdf/nycdot_std_details_const.pdf.
Adjoining Existing and New Sidewalks—Junctions and transitions
between new and existing sidewalks must conform to specifications.
