3.01 SEWER/CULVERT REMOVAL AND ABANDONMENT

A. When removing or abandoning a sanitary or a storm drainage structure, any live sewers connected to them shall be rebuilt and properly reconnected through the removal area. Services shall be maintained during these construction operations using bypass pumping.

B. If the plans call for abandoning a sanitary or a storm drainage structure, the existing frames, covers and grates shall be carefully removed to prevent damage and the structure broken down to 3 feet (91.4 cm) below the pavement subgrade or at least 3 feet (91.4 cm) below the final ground elevation outside the pavement area.

C. Existing castings shall be considered as salvaged castings. Salvaged castings not suitable for use and not required for structures to be adjusted, shall become the Contractor�s property and shall be promptly removed from the job site. When special catch basin abandonment is called for in the Proposal and at locations shown on the Plans, the catch basin line shall be plugged at the lateral sewer as detailed on the Standard Plans. This special abandonment shall be used in site clearance and urban areas where the lateral sewer is remaining in service.

D. All pipe culverts specified to be removed, including all end treatments shall be completely removed.

E. Where existing culvert pipe is to be extended or the existing end treatment is to be replaced, only such portions of the existing culvert pipe shall be removed as to provide a proper connection to the new work. Care shall be taken to not damage any portion of the remaining culvert pipe.

F. All pipe culverts to be abandoned shall be bulkheaded as specified herein or by other approved methods. If the culvert is not in suitable condition for abandonment, in the judgment of the Engineer, alternate methods will be determined.

G. Culvert pipe designated to be abandoned, with top elevation within 6 feet (18.3 m) of the top of the pavement, shall be reviewed for removal.

H. Disposing of Materials. All excavated materials, together with all debris, stones, logs, stumps, roots, and other unsuitable materials, shall be removed from the site and disposed of by, and at the expense of, the Contractor.

I. Backfilling. Backfill the excavated areas with Aggregate 21AA. Backfilling shall be placed and compacted according to MDOT Controlled Density Method at least to 95 percent maximum weight.

J. All sewers (storm, sanitary, or combined) or parts thereof which are specified to be removed, or that interfere with the new construction, shall be removed.

K. Where existing sewers are to be extended or otherwise incorporated into the new work, only such part of the existing sewer shall be removed as to provide a proper connection to the new work.

The connecting edges shall be cut, chipped, and trimmed to the required lines and grades without weakening or damaging the parts of the sewer to be retained.

L. Backfilling Abandoned Sewers. All sewers to be abandoned shall be bulkheaded with Grade 30 P concrete or with brick block masonry. A bulkhead shall be constructed from the inner wall of the drainage structure a minimum of 2 foot (61.0 cm) into the pipe or other method. If the sewer is not in suitable condition for abandonment, in the judgment of the Engineer, an alternate treatment will be determined.

M. An alternate procedure for backfilling abandoned sewers is to fill the sewer with grade 30M concrete or with grout composed of 2 parts sand to 1 part cement or variations thereof as may be approved by the contracting officer.

N. Backfill concrete shall be deposited through drop pipes placed over the abandoned sewer and at locations approved by the Engineer. Drop-pipe holes shall be spaced at intervals that will ensure the proper and complete filling of the sewer. All drop holes shall be sleeved for their entire length with a metal casing. The casing shall extend completely through the wall of the sewer. The drop-pipe shall be fitted with suitable and sufficient baffles to ensure the re-mixing of the concrete rather than a separation of the materials. The size of the drop-pipe shall be adequate for the placing of the concrete mix.

O. When the drop holes are no longer needed and the Engineer orders their abandonment, the castings shall be removed so that adjacent structures, utilities, and pavement will not be damaged. The hole shall then be filled with a 1500 psi concrete mix to within 5 feet (1.5 m) of the
