This work consists of removing all buildings, fences, guardrails, structures, old pavements, conduits, storage tanks, septic tanks, privy vaults, and other obstructions not designated or permitted to remain, and disposing the removed items in accordance with the requirement of 105.16 and 105.17. This work also consists of backfilling the resulting trenches, holes, and pits, and salvaging designated materials according to 202.02.
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 Proposal does not indicate for storage or for reuse, take ownership of the material.
Use all suitable material in the work. Alternatively, legally use, recycle or dispose of all removal items 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, and when the removal item is under the proposed pavement or paved shoulder, backfill the resulting cavities, voids, or trenches with Item 603 Structural Backfill Type 1 or 2. When backfilling is required, and when the removal item is outside the proposed pavement or paved shoulder limits or when rollers greater than 8 tons (7.25 metric tons) are used, the Contractor may use Item 203 embankment material. Place and compact the embankment or Item 603 Structural Backfill according to Item 203.
For areas backfilled 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.
Excavate the caved material in trenches and cavities resulting from the removal operation, and backfill the trench and voids according to the above specification, except when the trench lies within the limits of subsequent excavation.
Check appendix for more details and for requirements of other material encountered in the project site.
The plans will include a note regarding the bridge removal, the note will usually include, the phasing of the demolition procedure, the requirement of the demolition plan, the specification of the equipment to be used, the necessary protection for water ways and traffic.
Before the demolition starts, the contractor should obtain an approval of the demolition plan, and notify the owners off all existing utility conduits using the structure. The contractor should disconnect all utilities according to local requirements.
Remove the substructures of existing structures, including piling, down to the proposed stream bottom. For those parts outside the stream, and for bridges that do not span over streams, remove substructures to a minimum of 1 foot (0.3 m) below proposed ground surface.
Where the plans call for the removal of portions of the structure, remove those portions with sufficient care. Avoid damage to the remaining portion of the structure. In case of damage to the existing structure, repair or replace the damaged portions of the structure at no expense to the Department.
Backfill the cavity created by the removal item according to 503.09, except when the cavity lies within the limits of subsequent excavation or other work.
The plans will include a note regarding asbestos on bridges, contact the District Environmental Coordinator (DEC) to check changes in the current law regarding Asbestos removal. For a typical plan note, see the section, “Typical Regulated Waste Plan Notes”, Asbestos Abatement. This note is similar but not the same as 202 Asbestos Pipe Removal specification requirements in Item 202.
The contractor should adhere to plans note and specification while conducting the removal.
If the existing conduit attached to the structure is not specifically denoted in the Contract Documents as Item 202 Asbestos Pipe Removed, perform the work according to 109.05.
Remove and store, or dispose of pipe, head walls, or culvert as specified in the Proposal for payment. Seal openings left in walls of manholes or catch basins that are to remain in place. Encountered inactive and to be abandoned pipes, should be plugged or sealed before proceeding with backfilling operations. Perform plugging by using approved precast stoppers. Perform sealing by using masonry bulkheads.
If the removed pipe is designated for storage, the contractor should 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, the contractor should carefully remove the remainder of the pipe and avoid breaking or damaging the pipe. Transport and store the removed pipe, as necessary before relaying. The contractor should 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, remove unusable pipe under Item 202 Pipe Removed.
Perform work according to 202.03 when removing conduits from or around a stream.
If removing an existing concrete water line 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 pipes at a solid waste facility that is licensed by the Local Health Department and permitted by the OEPA. Contact the District Environmental Coordinator (DEC) to check changes in the current law regarding Asbestos removal.
If the existing conduit attached to the structure is not specifically denoted in the Contract Documents as Item 202 Asbestos Pipe Removed, perform the work according to 109.05.
Asbestos is not a hazardous waste or a solid waste; it is a special waste. This pipe is regulated and must be removed and disposed of properly. .
When evaluating the potential for asbestos in the pipe, the project should look at the "Markings" on the pipe. Concrete underdrain, waterline, and sanitary sewer pipe with the following “Markings” are known to contain asbestos:
1.
ASTM C-663
2.
AASHTO
M-217
3.
AWWA-C-400-64-T
4. ASTM-C-296-65-T
Individual utility companies and Local Planning Associations (LPA's) may have used asbestos pipe under their own specifications.
Asbestos Cement Perforated Underdrain Pipe was allowed in 706.15 in the 1970's. In addition, Asbestos Bonded Bituminous Corrugated Steel Pipe and Pipe Arches were allowed in the 1980's in 707.09.
Test the pipe for asbestos if there is any doubt about the pipe’s composition or identity.
Asbestos inspectors in
There are a multitude of rules, laws, and regulations that govern asbestos operations. One of the best web sites is:
http://www.ehso.com/Asbestos/asbestreg.php
In addition, more information can be found under the Ohio Revised Code 3745-20 or the Ohio Administrative code OAC-3701-34 at the following web site:
http://onlinedocs.andersonpublishing.com/oac/
http://onlinedocs.andersonpublishing.com/revisedcode/
Asbestos removal Contractors must obtain the Asbestos Hazard Abatement Specialist license or Asbestos Worker License from Ohio Department of Health (ODH). Each asbestos removal company also needs to have an Abatement Contractor license through ODH as well.
The training requirements are under CFR 1926.1101(9) (i-viii) requirements for the truck drivers to haul the asbestos. The only training required for the truckers to haul the asbestos is two hour OSHA Awareness training.
It is highly recommended that the Project hire a third party ‘Certified Asbestos Inspector’ to provide oversight during the removal.
Concrete pipe is non-friable asbestos. The pipe becomes friable if it is chipped, crumbles, or crushed during the removal. Therefore, the same requirements are required for friable and non-friable asbestos pipe. Cutting and crushing the asbestos pipe is strictly forbidden. Follow the instructions of the asbestos inspector or contractor.
The project may need to notify the local air quality authority and follow strict OSHA demolition and removal requirements.
The material must be taken to a solid waste facility that is licensed by the Local Health Department. See the boiler plate note listed under 202.04 at the following link:
http://www.dot.state.oh.us/construction/OCA/Specs/SSandPN2005/default2005.htm
Manifesting for disposal is required. The Regulated Waste Project Engineer or the District Environmental Coordinator is required to sign the Manifest for the Department. See Appendix 202 Regulated Waste Requirements, “Manifesting” for more information.
The plans will designate the items for removal using a balloon with (R for Removal) attached to a line pointing out the removal item. As designated, remove and dispose of the existing Item. If removing only a portion of an existing item saw cut a neat joint at the removal limit.
Pavement Removal limit will be detailed in 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. If 202 Base Removed is specified in the Contract, remove the specific layer as shown on the plans. If Item 202 Pavement removed in the plan, remove all asphalt, concrete, or brick from the surface to the bottom.
Whether the building is located partially or totally on temporary or permanent Right-of-Way perform the demolition the same.
The contractor should disconnect all utilities according to local requirements, and notify the owners of water, electric, or gas meters when the meters are ready for removal.
The contractor should not disturb buildings until the Engineer provides a Notice of Possession and Approval to Proceed. The demolition should be performed under the Engineer’s direction in order to accommodate utility rearrangements and clearance of structures.
The Contractor may use buildings for storage, or other purposes. The Engineer should secure a documented agreement, to allow such use during the period of the Contract, and save the Department harmless from any claims whatsoever by reason of such use.
Raze the building (including all items) to a minimum of 1 foot (0.3 m) below the grade of the surrounding area.
Break up and remove all floor slabs under which a pit, well, cistern, or tank exists. Completely remove all tanks and clear basements of all materials, so only masonry walls and concrete basement floors remain. Break up basement floors to be left in place, and seal remaining drains with masonry or with precast clay or concrete stoppers.
If the building contains any hazardous materials that require remedy before the start of the demolition, perform the necessary work under other items in the Contract or according to 109.05.
The Engineer should approve the demolition work and the contractor should immediately backfill the cavity created.
All structures torn down by the Department are required to have an Asbestos Inspection. Ensure that the Office of Real Estate performed these asbestos inspections. An Ohio EPA form ‘Notification of Demolition and Renovation’ must be filled out by the Department or the contractor Ten days prior to the Demolition.
This form details the type and quantity of asbestos removed and small amount of asbestos left in the building. Generally, the Asbestos Abatement Contractor performs all of the asbestos removal. In rare cases, the asbestos abatement is performed under the highway contract.
The instructions and more details can be found at the following link:
http://www.epa.state.oh.us/dapc/atu/atu.html#Asbestos
Normally, friable asbestos cannot be left in the building during demolition. In rare cases, the asbestos abatement Contractor may leave a small amount of asbestos in the structure. Of course, large amounts of asbestos cannot be crushed or rendered friable. If the amount of asbestos is small and the ‘Notification of Demolition and Renovation’ allows the building to be demolished, then this material can be hauled away to a Construction and Demolition Land Fill if allowed by the local Board of Health.
If asbestos is left in the building, the building cannot be burned. Even if the Notification of Demolition and Renovation allows the building to be burnt.
The Notice will specifically mark on the form that the building can be burnt. In addition, an Open Burning Permit would be required if the structure is burned.
Burning or disposing of the building is allowed in 105.16 and 105.17. The Contract will specifically state whether burning is restricted due to the asbestos left in the building. This restriction will be based on the ‘asbestos’ remaining in the building, and not on the Ohio Administrative Code (OAC) 3745 in 105.17.
Contact the Office of Real Estate, Regulated Waste Project Engineer or District Environmental Coordinator for a clear recommendation on the disposal.
Prior the start of the demolition work, empty all septic tanks and privy vaults. Dispose of the removed contents in a manner that conforms to the requirements of the State and Local Boards of Health or other authorities having jurisdiction.
Completely remove and dispose of septic tanks and privy vaults located above the subgrade or finished ground surface. For septic tanks and privy vaults located below the subgrade or finished ground surface, remove tops and walls to a minimum depth of 3 feet (1 m) below subgrade or 1 foot (0.3 m) below finished ground surface. Break up floors and seal remaining drains with masonry or with precast clay or concrete stoppers.
Underground tanks are either regulated or unregulated. The proposal pay item will detail the difference by specifying the unregulated underground tanks as Item 202 Under Ground Storage Tanks Removed and the regulated tanks as Item 202 Regulated Underground Storage Tank Removed.
If an unidentified underground storage tank is encountered, the Project Engineer should notify the Regulated Waste Project Engineer, District Environmental Coordinator, local fire authority, or BUSTR immediately.
Prior the start of the demolition of the unregulated underground tank, empty the tanks and dispose of the removed contents in a manner that conforms to the requirements of the State and Local Boards of Health or other authorities having jurisdiction.
The procedure to remove the regulated underground tanks is complex. Contact the District Environmental Coordinator (DEC) to check changes in the current laws and regulations.
Obtain the required permit prior the start of the demolition procedure. Provide an independent non-Contractor employee BUSTR inspector or a State Certified BUSTR inspector to perform the BUSTR required inspections. Remove and dispose of the tank and its contents 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. Provide a Certified Tank Installer to supervise the removal. For tanks containing hazardous substances other than petroleum, use and comply with the Ohio EPA regulations in addition to State Fire Marshal regulations.
Test the excavated material, 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, and prepare the closure report.
More details on the requirements for regulated underground tank removals
The state fire marshal and OEPA generally follow BUSTR
regulations. The State Fire Marshals
Office, Bureau of Underground Storage Tank Regulations (BUSTR), controls the
vast majority of the installations, uses, and removals of underground storage tanks
in
See the BUSTR Web site for more information. Valuable information can be found by looking up ‘download’ documents. Additional information can be found by looking at the fact sheets at the following web location:
https://www.com.state.oh.us/odoc/sfm/bustr/Downloads.htm
Project personnel must review the fact sheets and this section of the manual to become familiar with the UST removals.
The types of tanks regulated by BUSTR are detailed on the Fact sheet entitled “What Type of Tanks does BUSTR Regulate”.
1. A ‘Certified Installer’ is required for any removal of an UST regulated by BUSTR. The Certified Installers are required to have photo identification. The project engineer should check for this identification. There is a list of the Certified Tank Installers on the web site.
2. A ‘Certified Inspector’ is required to inspect the work. This inspector may be from the local fire department, BUSTR, or a consultant who is a Certified Inspector. The Contractor must supply this person as part of the bid work. There is a list of these inspectors on the BUSTR web site.
3. A permit must be applied for 30 days prior to the work. The Project Engineer should obtain a copy for the project records. The local fire department or BUSTR may issue the permit. A permit may be required by BUSTR and the local fire department. See the Fact Sheet entitled “The BUSTR Permit Process.” A copy of a permit application is on the web site.
4. Even though the permit may be issued by the local fire department, BUSTR must receive a copy of the permit application 30 days prior to the removal.
5. Tank registration may be required if the tank is not registered. See the Fact Sheet entitled “Underground Storage Tank Registration”. Since the Department typically is the owner, the District Environmental Coordinator registers the tank. In rare cases the Project Engineer can register the tank. This form is on BUSTR’s web site.
a. For unidentified tanks, the owners are typically unknown.
b.
If a tank was last used prior to
6. The local Division of Air Pollution Control of the Ohio EPA may need to be notified because of air pollution concerns. See the Web site location Division of Air Pollution Control in the 105.16 Borrow and Waste “Open Burning”.
7. The actual removal is summarized in the Fact Sheet entitled “Closure Guidelines”. See the section on permanent removal and replacement. The Certified Inspector must sign the permit and the project should keep a copy for a permanent record.
8. A closure assessment and report is required after the UST removal. The Contractor is required to submit the report to BUSTR within 45 days of the closure. The Regulated Waste Project Engineer should sign the closure report for the Department. The Regulated Waste Project Engineer may elect to have this closure report reviewed by an environmental consultant.
9. The District must keep the closure report “Forever”. The report should be given to the Regulated Waste Project Engineer and/or District Environmental Coordinator. The Regulated Waste Project Engineer must ensure that these records are given to the District Environmental Coordinator for final record keeping.
10. Depending on the result of the closure assessment, a risk assessment and remedial action may be needed. If these two are required an Environmental Consultant will be needed to perform this work. The task order contract may be used to perform this work. See the Fact Sheets entitled “Risk Assessment”, “Remedial Action Plan Guidelines” and “Selecting an Environmental Consultant” on the web site. Contact the Regulated Waste Project Engineer and/or District Environmental Coordinator.
11. The specification requirements in 202.08 do not cover risk assessment, remedial action, environmental cleanup, or the cleanup of the plume beyond a few feet outside the UST. Any of this work should be considered extra work unless additional quantities or other work is described in the plans or proposal.
The following personnel must be contacted when the UST is removed and 25 gallons or more of petroleum is released, or if the product reaches a body of water or travels off the project site. Project Personnel should use the following web site during a release: http://www.epa.state.oh.us/derr/ersis/er/er.html
1. Immediate Notification:
a. Regulated Waste Project Engineer
b. District Environmental Coordinator
c. Local Fire Department
d. The OEPA Emergency Response Unit at 800-282-9378
2. BUSTR Corrective Action Hotline at 800-686-2878 within 24 hours
3. Contact all of the following if a Hazardous chemical in excess of its reportable quantity is released:
a. Regulated Waste Project Engineer
b. District Environmental Coordinator
c. Local Fire Department
d.
The
Reportable chemical quantities may be between 1 and 500 pounds depending on the chemical. The web site refers to Code of Regulation (CFR) that gives the reportable quantities limits. In addition, it gives explicit instructions about what action should be taken by the project personnel.
The Contractor and the Regulated Waste Project Engineer should know the reportable quantities prior to the UST removal.
At some point, the project should hire an environmental consultant to help with the required paper work.
When guardrail or fence is designated for reuse or storage by the Department, Carefully dismantle and store existing guardrail including anchor assemblies, terminal assemblies, attached posts, signs, delineators and fence. Otherwise, dispose all removed material according to 202.02. Wood posts are not considered salvageable.
If guardrail is next to a lane maintaining traffic, do not remove the guardrail until the replacement material is on the site and ready for installation. Do not leave hazards unprotected adjacent to a lane maintaining traffic, except for the actual time required to remove the existing guardrail and install the proposed guardrail in a continuous operation. The Engineer should suspend work for failure to comply with this requirement.
When fence is designated for replacement, do not remove the existing fence until the replacement material is on site. Begin the new installation within 7 workdays of beginning the removal process.
Remove raised pavement markers in concurrence with the maintenance of traffic phases so that their existence or removal will not conflict with the temporary pavement markings or the snow and ice removal.
Remove all standing water and fill with asphalt concrete, by the end of the next workday, depressions caused by removing the castings. Compact the asphalt concrete flush with the pavement.
Remove existing drainage structures of the types designated for removal and take ownership of castings unless otherwise noted on the plans.
Remove existing drainage structures of the types designated to be abandoned to a minimum of 1 foot (0.3 m) below the finished subgrade or ground surface.
Do not damage pipes that are to remain.
Connect existing pipes with new pipe through the structures. Seal the existing inlet and outlet pipes with precast vitrified or concrete stoppers or with masonry of a type and thickness to fill the inlet or outlet pipe. Carefully hand tamp backfill under and around the pipe according to 202.02.Method of Measurement/Basis of Payment (202.13) & (202.14)
The following are in addition to the requirements of 202.13 and 202.14:
Items encountered that are obstructing the constructing of the roadway as intended, are necessary to be removed, in order to remove the items specifically denoted in the Contract, or are at the same location where proposed items of work such as drainage structures are to be constructed, should be removed and paid for under other items in the Contract or according to 109.05.
Reconstruct and pay for items of work not detailed in the plans, such as pavement and curbs necessary to be removed in order to remove Contract removal items, in accordance with the specifications of other similar items in the Contract or according to 109.05.
