Removal

202.1DESCRIPTION

1 This section describes the requirements for removing and disposing of obstructions or appurtenances not specified to remain; salvaging material; backfilling trenches, holes, and pits; and removing and resetting mailboxes.

202.2MATERIALS

1 Provide mailbox components as specified . Provide galvanized nuts, screws, bolts, and hardware.

202.3EQUIPMENT

1 If the contract includes pay items Milling Plant Mix, Milling Concrete, or Profile Milling Plant Mix, remove the existing pavement using a power -operated milling machine. Provide a machine equipped to perform the following:

single pass.

from an independent grade control, and with a positive means of controlling cross slope elevations.

Profile Milling Plant Mix, ensure the machine is equipped with a 30-foot [10 m]

2 Other equipment providing the same or better results may be used for removal, with the approval of the engineer.

3 Cut bituminous pavement with a saw. Other equipment may be used if cuts are demonstrably equivalent, with the approval of the engineer.

4 Cut concrete using a saw with diamond blades.

Removal SECTION 202

202.4CONSTRUCTION

202.4.1 General

1 Raze, remove, and dispose of buildings, foundations, structures, fences, and other obstructions as specified. Do not remove utilities and items for which other provisions have been made.

2 Backfill basements, cavities, and trenches left by structure removal to the level of the surrounding ground. Compact backfill in embankment areas in accordance with Subsection 203.4.3, Embankment and Cut Areas with Moisture and Density Control.

3 Backfill holes created by the removal of posts. Place and compact backfill material in 8-inch [200 mm] lifts until even with the existing ground surface. Backfill holes in plant mix surfaces with new hot plant mix surfacing material or other material approved by the engineer in thicknesses equivalent to the depths of the existing surfacing material.

4 Without damage, remove materials specified for salvage in pieces that can be transported, and stockpile them at specified locations. Replace with new material, at no additional cost to the department, those materials specified for salvage that are damaged during removal, transport, or stockpiling operations.

5 Materials removed and not specified for salvage, recycling, or incorporation into the work become the property of the contractor. Do not dispose of removed materials within the right-of-way, construction permit areas, pits, or viewshed of any roadway.

202.4.2 Removal of Structures

1 Do not remove structures used by traffic until provisions have been made to maintain traffic flow.

2 Remove substructures to a depth of 3 ft [1 m] below the streambed, if applicable. Remove items not in a streambed to a depth of 12 in [300 mm] below the natural ground surface. Where portions of existing structures lie entirely or partially within the limits of a new structure, remove as necessary to accommodate construction.

3 If specified, dismantle bridges designated for salvage and matchmark the members.

4 Steel and timber bridge components may contain hazardous materials; the contractor is responsible for mitigation.

5 Dismantle, transport, and dispose of structural steel bridge components in compliance with governing regulations. Transport the structural steel bridge components to a recycling facility. Give the engineer documentation of the facility’s receipt.

6 Do not burn timber bridges in place.

Removal SECTION 202

7 Remove existing structures or obstructions without damaging new work, appurtenances, or existing roadway that is to remain in place . If blasting is necessary, give the engineer the following information at least 14 calendar days before blasting begins:

202.4.3 Removal of Guardrail, Barrier, Bridge Railing, and Pedestrian Railing

1 Removal of existing guardrail and barrier includes rail, posts, spacer blocks, associated hardware, bridge rail connections, and end anchorages . Remove concrete post foundations, anchorage blocks, and barrier foundations.

2 Removal of bridge railing and pedestrian railing includes rail, posts, associated hardware, and anchor bolts, if specified. Bridge railing components may contain hazardous materials; the contractor is responsible for mitigation.

202.4.4 Removal of Pipe, Flared End Sections, and Storm Sewer Systems

1 Remove and clean pipes and flared end sections, storm sewer systems, manholes, and inlets specified for salvage.

202.4.5 Removal of Surfacing, Concrete, Sidewalks, Curbs, Gutters, Median, Double Gutter, Etc.

1 Remove concrete, plant mix, base course, sidewalks, curbs, gutters, double gutters, median, etc., specified for removal using one or more of the following methods:

less. Provide a site and dispose of the pieces.

Saw-cut concrete pavement full -depth. Repair at no additional cost to the department, spalling, cracking, breaking, or similar damage of the existing pavement or appurtenances that are to remain in place.

the surface to the grade and width and at the locations specified.

When Profile Milling Plant Mix is specified, milling depths will vary across the roadway’s length, width, or both.

W ork may include transition milling into structures, into project tie- ins, at box culverts, and at the beginning and end of project transitions.

Removal SECTION 202

Conduct milling operations parallel to the travel lanes, unless otherwise approved by the engineer.

Dispose of slurry from concrete milling operations as specified.

Correct vertical differences greater than ⅜ inch [10 mm] between adjacent peaks and valleys of the milled plant mix surface, and ⅛ inch [3 mm] between adjacent peaks and valleys for concrete surfaces . Correct surface irregularities resulting from milling activities using cold milling or other operations approved by the engineer, at no additional cost to the department.

Stockpile removed material not designated for recycling, incorporation into the project, or immediate use at a specified site. Place the material without operating equipment on the stockpiles.

remove ballast, gravel, plant mix material, crushed base, sub- base materials, or other surfacing materials; stockpile or dispose of them at specified sites. If removed materials will be incorporated or stockpiled as reused surfacing or base, remove without contamination from underlying materials.

surfacing that is to remain, cut the pavement along the limits of removal.

Make a vertical cut deep enough to allow removal of the pavement and base, if applicable, without leaving a ragged edge or damaging the adjacent pavement. Vary the depth of cut as dictated by changes in the thickness of the pavement.

202.4.6 Removing and Resetting Mailboxes

1 As necessary, move and maintain mailboxes to ensure accessibility by mail carriers during construction.

2 Mount reset mailboxes on new posts, unless the old posts and mountings comply with contract requirements. Whenever possible, reset existing mailboxes. Return posts and mailboxes that are removed and not reused to the landowner.

202.4.7 Removal of Fence, Snow Fence, and Signs

1 When fence removal includes salvage, roll salvaged wire into rolls no larger than 3 ft [1 m] in diameter.

2 Backfill and compact holes left after the removal of posts, anchors, and other components.

3 If the snow fence anchors will not come out of the ground, cut the anchors off 6 in [150
