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 remain, 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 recycle or 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 (7 metric tons) 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 (0.3 m) 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.
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.
202.04
Pipe Removal. Remove
and reuse, store, or dispose of pipe, or culvert 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,
and remove and dispose of pipe headwalls.
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 stoppers. 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, or Traffic Dividers Removed. As
designated, remove and dispose of the existing wearing course, concrete base
course, concrete pavement, asphalt wearing course on brick or concrete base,
concrete walks, concrete steps, concrete gutters, stone or concrete curbs, and
concrete traffic dividers. If removing only a portion of an existing
pavement, walk, step, gutter, curb, or traffic divider, saw or otherwise cut a
neat joint at the removal limit if it does not occur at an existing joint.
If
Item 202 Pavement Removed is specified in the Contract,
remove all asphalt, concrete, or brick from the surface to the bottom of the
pavement courses as shown on the plans. If 202 Base
Removed is specified in the Contract, remove the specific layer as shown on the
plans. If Item 202 Wearing Course Removed is
specified in the Contract, remove all asphalt from the surface to the top of
the concrete or brick or remove the specific layer or layers shown on the
plans.
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 building 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 (0.3 m) 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.

Storage Tank Removed. Remove and dispose of underground storage
tanks or regulated underground storage tanks, as designated in the Contract
Documents, and according to the requirements of the authorities having
jurisdiction.
If
Item 202 Regulated Underground Storage Tank Removed is
specified in the Contract, remove the tank according to the Bureau of Underground Storage
Tank Regulations of the Division of Fire Marshal (BUSTR),
Ohio EPA, and all applicable Federal,
State, and local regulations. Removal includes obtaining the required permit,
disposing of the tank and its contents, testing the excavated material, and
preparing the closure report. Provide a Certified Tank Installer to
supervise the removal. Provide an independent non-Contractor employee BUSTR inspector or a State Certified BUSTR
inspector to perform the BUSTR required
inspections. For tanks containing hazardous substances other than
petroleum, use the Ohio EPA
regulations in addition to State
Fire Marshal regulations.
Completely
remove regulated underground storage tank and contents. Take ownership
and dispose of tanks according to 202.02 and the
above requirements. If because of leakage from the tank, any contaminated
water or soil disposal or remediation is required, perform the necessary work
under other items in the Contract or according to 109.05.
If

cavities according to 202.02. If using
connecting pipes, carefully hand tamp backfill under and around the pipe
according to 202.02.
202.13
Method of Measurement. If the
Contract specifies that removal of structures and obstructions is on a lump sum
basis, the work will include all structures or obstructions encountered at
locations or within areas designated in the Contract Documents. However,
the Department will measure asphalt wearing course removal on a bridge separate
from the lump sum item for structure removal.
If
the Contract specifies that removal of specific items is on a unit basis, the
Department will measure the quantity of each item by the unit stipulated in the
Contract. If removal of steps is measured by the foot (meter), the Department
will measure the number of feet (meters) along the front edge of each
tread. If the steps have an integral wall, the Department will include
the thickness of the integral wall with the tread width measurement.
202.14 Basis
of Payment.
Payment is full compensation for all work involved in the removal and storage,
