SECTION 202
REMOVAL OF STRUCTURES, OBSTRUCTIONS,
SURFACING, AND MISCELLANEOUS ITEMS
202.01 GENERAL.
This work consists of razing, removing, salvaging, and disposing of items not designated to
remain, salvaging designated materials, and backfilling resulting cavities.
202.02 EQUIPMENT.
202.03 MATERIALS.
202.04 CONSTRUCTION REQUIREMENTS.
A. General.
Remove designated salvage material without damage and place at the specified
location.
Remove existing bituminous and concrete surfaces to a joint or saw a full-depth vertical
cut along the entire length of the butt joint.
Backfill basements and cavities left by structure removal as specified in Section 201.04
B. Before backfilling, break remaining concrete slabs for drainage. Backfill and compact
cavities within the embankment area as specified in Section 203.04 E. Backfill and
compact cavities outside the embankment area to the same level as the surrounding
undisturbed ground.
B. Removal of Bridges and Box Culverts.
Remove portions of existing structures that interfere with the new structure. Remove
existing substructures to the natural stream bottom, and remove those parts outside the
stream to one foot below natural ground surface.
Dismantle and match mark the bridges designated for salvage. Transport to specified
location.
Ensure the removal and blasting operation does not damage the new structures.
C. Removal of Pipe Conduit.
Remove and store pipe conduit designated for salvage without damage. Replace
sections of pipe damaged by negligence or lost from storage. Dispose of excess
excavation off the right of way at an approved location.
D. Plugging Existing Pipe Conduit.
Plug existing PVC pipe with an approved PVC cap. Plug other existing pipe using one of
the following methods:
1. Compacted Earth.
Plug the existing culvert ends with compacted earth.
2. Concrete.
Remove a minimum of 6 feet of the barrel section where it joins a structure.
Place concrete in the remaining ends of the barrel section. Use an approved
available local concrete mix. Cap the remaining ends with an approved PVC cap.
Ensure that the existing pipe conduit is removed a minimum of 2 feet from the
outside of the new pipe conduit
3. Precast Concrete Plugs.
Use precast concrete plugs to plug conduit ends.
4. Pressurized Grout.
Plug existing pipe culverts using the pressure grout method. Excavate to locate and
pressure grout the pipes on the high water side of the embankment. Locate the pit at
least 15 feet off the centerline of the roadway. Use trench boxes and shoring as
required.
After locating the pipes, make a hole in the top of the pipe. Pump water out of pipe
before placing grout. The Engineer will allow placement of the grout under wet
conditions if seepage prevents dry conditions. In either case, completely fill the pipe
with grout that attains an unconfined compressive strength of at least 150 psi within
28 days. The Engineer will test the grout in accordance with the FSTM. The
Engineer will take grout samples every 14 CY for compressive strength. Do not
exceed grout injection pressures of 50 psi.
Calibrate all equipment before beginning work. Ensure the grout pump has a liquidfilled diaphragm in-line gauge. Use tremmie grouting for grout injection. Continue
grout pumping until refusal or until grouting pressures reach the predetermined
maximum.
E. Removal of Bituminous Materials.
Remove all material salvaged for reuse as base material. Ensure salvaged material is
not contaminated with dirt or other foreign material.
Remove and salvage bituminous pavement scheduled for use as bituminous surfacing
as specified in Section 405.
F. Removal of Concrete Materials.
Remove all reinforcing steel from the existing concrete pavement. Do not stockpile the
reinforcing steel within the right of way.
Remove and salvage concrete pavement for use as recycled concrete pavement as
specified in Section 560.
G. Removal of Manholes and Inlets.
Remove manholes or inlets by removing the casting, rings, barrel and base; plugging or
capping the existing lines; and backfilling to grade.
H. Removal of Monuments and Markers.
Remove designated monuments or markers.
202.05 METHOD OF MEASUREMENT.
The Engineer will measure as specified in Section 109.01 and as follows:
The Engineer will include the reinforcing steel in the total weight when the Department pays for
removal of concrete pavement by the ton.

Such payment is full compensation for furnishing all materials, equipment, labor, and incidentals
to complete the work as specified
The Engineer will adjust payment for grout dependent on compressive strength of the samples.
The Engineer will reduce the payment for each 14 CY of grout represented by the sample 25
percent for every 5% the tested compressive strength is below the specified 150 psi.
Removals of designated monuments or markers will be at no cost to the Department.
Exclusions. When the Bid Schedule does not contain an estimated quantity or a Lump Sum
item for “Removal of Structures and Obstructions,” and the structure or obstruction is shown on
the Plans, the Department will not pay for the work directly, the payment will be included in other
Contract Items. If the structure or obstruction is not shown on the Plans and the Engineer
directs removal, the Department will pay as specified in Section 104.03.
Include the cost for excavation and disposal for removal of pipe conduit in the price bid for
“Removal of Pipe All Types & Sizes”.
