202Removal of Structures and Obstructions

202.01 Description. This work consists of removing, entirely or in part, and disposing of all

buildings, fences, guardrails, structures, old pavements, abandoned pipe lines, storage tanks, septic tanks, privy vaults, and other obstructions not designated or permitted to rema in, except for utilities and obstructions to be removed and disposed of under other items in the Contract. This work also consists of backfilling the resulting trenches, holes, and pits, and salvaging designated materials. When specific pay items for removal of structures and obstructions are not listed in the Contract Documents, perform this work under Item 203.

202.02 General Construction Requirements. Raze, remove, and dispose of all buildings and

foundations, structures, fences, guardrails, old pavements, abandoned pipe lines, storage tanks, septic tanks, privy vaults, and other obstructions within the Right-of-Way, except for utilities and those items where other provisions have been made for removal. Remove and store, at the specified locations within the Project limits, or reuse all designated salvageable materials. The Department will take ownership of all salvageable items specified for storage. Reuse all salvageable items specified for reuse on the project. When the Contract Documents do not indicate for storage or for reuse, take ownership of the material. Use removed or excavated materials in the Work when the material conforms to the specifications; if not, then dispose of the material according to 105.16 and 105.17. Do not remove any item in use by traffic until after making arrangements to accommodate traffic. When backfilling is required, backfill the resulting cavities, voids, or trenches with either Item 203 embankment material or Item 611 Structural Backfill Type 1 or 2. Use Item 611 Structural Backfill when the removed item is under the proposed pavement or paved shoulder and when the site limits the use of compaction equipment larger than an 8 -ton roller; otherwise the Contractor may use Item 203 embankment material. Place and compact the embankment or Item 611 Structural Backfill according to 203. For backfilled areas outside the plan construction limits, provide a final grade that presents a neat, well-drained appearance that conforms to the final topography and prevents water from draining onto adjacent properties.

202.03 Structures Removed. Remove bridges, culverts, and other structures indicated for

removal in the Contract Documents. If within a stream, remove the substructures of existing structures, including piling, down to the proposed stream bottom. For those parts outside the stream, remove substructures to a minimum of 1 foot below proposed ground surface. Remove, as necessary, those portions of existing structures that lie entirely or partially within the limits for a new structure to accommodate the construction of the proposed structure. Where alteration of an existing structure requires removal of portions of the structure, remove those portions with sufficient care as to avoid damage to the remaining portion of the structure. In case of damage to the existing structure, repair or replace the structure at no expense to the Department. Remove any existing welded form hangers, welded attachments two inches or longer measured parallel to the long axis of the top flange of steel beams or girders, and welded attachments that interfere with the placement of welded shear connectors. Any items from this list not shown in the bid documents shall be removed per 109.05. If removing a bridge or portion of a bridge with an asphalt wearing course, remove the wearing course separately before removing the bridge or portion of the bridge. Backfill the cavity created by the removal item according to 202.02, except when the cavity lies within the limits of subsequent excavation or other work. Demolition of bridges or portions of bridges in which the work endangers property or the welfare, life, health of any individual requires an engineered drawing and meeting according to 501.05.

202.04 Pipe Removal. Remove and reuse, store, or dispose of pipe, or culvert, including

headwalls, as specified in the Contract Documents. If removing an existing concrete waterline pipe that was constructed before 1980, it may be an asbestos pipe. Test the pipe by using a Department prequalified environmental consultant to determine if it is an asbestos pipe. If it is determined that the pipe is asbestos, then a certified asbestos Contractor must perform the removal. Dispose of all asbestos pipe at a solid waste facility that is licensed by the Local Health Department and permitted by the OEPA. Seal openings left in walls of manholes or catch basins that are to remain in place. If an adjacent existing pipe is encountered during removal operations and the pipe is inactive or is to be abandoned, plug or seal the remaining ends of the pipe before proceeding with backfilling operations. Perform plugging by using approved precast stop pers. Perform sealing by using masonry bulkheads. Remove a sufficient section of the pipe to allow the Engineer to determine the quality of the pipe and the possibility of its removal without damage to pipe specified for reuse or storage. If the Engineer determines the pipe is salvageable, carefully remove the remainder of the pipe to avoid breaking or damaging the pipe. Transport and store the removed pipe, as necessary before relaying. Replace sections of pipe lost or damaged by negligence or by use of improper methods at no additional cost to the Department. Clean all pipe before reusing. Remove salvageable pipe under Item 202 Pipe Removed for Reuse or Storage. If the Engineer determines the pipe is unusable, take ownership of the pipe, and dispose of or recycle it according to 202.02. Remove unusable pipe under Item 202 Pipe Removed. Before backfilling the trench, excavate the caved material, as necessary. Backfill trenches resulting from the removal of pipe according to 202.02, except when the trench lies within the limits of subsequent excavation or other work.

202.05 Pavement, Walks , Curbs, Steps , Gutters, Concrete Slope Protection, or Traffic

Dividers Removed. As designated, remove and dispose of the existing concrete pavement, asphalt pavement, wearing course, brick, walks, steps, gutters, curbs, and concrete traffic dividers. If removing only a portion of an existing pavement, walk, step, gutter, curb, or traf fic divider, saw or otherwise construct a neat joint at the removal limit. If Pavement Removed is specified, remove all pavement layers, including asphalt, concrete, and brick, from the surface to the bottom of the pavement courses as shown on the plans. Pavement Removed does not include removal of any unbound aggregate or natural soil mate rial. If Wearing Course Removed is specified, remove all asphalt from the surface to the top of the concrete, brick, or both, or to the depth shown on the plans. If the existing surface is brick and Wearing Course Removed is specified, remove all brick fro m the surface. If Concrete Median Removed or Concrete Barrier Removed is specified, remove all the concrete to the depth specified in the plans. As designated, remove and dispose of the existing concrete slope protection, including tied concrete block mats. If removing only a portion of an existing concrete slope protection, saw or otherwise cut a neat joint at the removal limit if it does not occur at a joint. Backfill the cavity created by the removal item according to 202.02, except when the cavity lies within the limits of subsequent excavation or other work.

202.06 Buildings Demolished. Do not disturb buildings and appurtenances designated for

demolition until the Engineer provides a Notice of Possession and Approval to Proceed. Immediately after receiving approval, schedule and perform the demolition under the Engineer’s direction in order to accommodate utility rearrangements and clearance of structures. Whether the build ing is located partially or totally on temporary or permanent Right-of-Way perform the demolition the same. The Contractor may use buildings located partially on and off the permanent Right -of-Way for storage, office, living quarters, or other purposes. The agreement shall allow such use during the period of the Contract and save the Department harmless from any claims whatsoever by reason of such use. Remove foundations; floors; floor slabs; and basement, pit, well, and cistern walls to a minimum of 1 foot below the grade of the surrounding area. Completely remove all tanks and clear basements of all materials, debris, appliances, wood or metal partitions, and wood floors so only masonry walls and concrete basement floors remain. Break up and remove all floor slabs under which a pit, well, cistern, or tank exists. Break up basement floors to be left in place, and seal remaining drains with masonry or with precast clay or concrete stoppers. Take ownership of all materials, except those belonging to a public or private utility. Notify the owners of water, electric, or gas meters when the meters are ready for removal. Disconnect all utilities according to local requirements. After completing demolition work and obtaining the Engineer ’s approval, immediately backfill the cavity created by the removal item according to 202.02, except when the cavity lies within the limits of subsequent excavation or other work.
