2104Removing Pavement and Miscellaneous Structures

2104.1DESCRIPTION

This Work consists of removing and disposing of pavement, sewers, Culverts, guardrails, abandoned Structures, and other obstructions on the Right-of-way, except as specified in 2442, “Removal of Existing Bridges,” and 2103, “Building Removal.” This Work also consists of salvaging Material and backfilling trenches, holes, and depressions.

2104.3CONSTRUCTION REQUIREMENTS

A General Remove and dispose of Structures and obstructions as required by the Contract. B Salvage Operations Remove, dismantle, and store salvaged Materials to allow reuse. When salvaging guardrail and fences, coil the wire and cable, pull posts from the ground, and remove nails and staples from posts and boards. Stockpile Materials designated for salvage by the Department on the Right-of-way at locations approved by the Engineer. Remove, dismantle, and clean Materials as required by the Contract before stockpiling. C Removal Operations C.1 Removing Portion of Structure Do not damage existing Structures to be retained for use during the removal operations. Ensure a length of at least 40 bar diameters from the face of the cut for existing reinforcement bars for concrete Structures left in place. C.2 Pavements and Sidewalks Saw the existing concrete pavement or Sidewalks or bituminous pavement at the locations as shown on the Plans and as staked by the Engineer to establish a neat line for extending the new Work. C.3 Concrete and Masonry Structures Remove concrete and masonry Structures to the excavation limits as shown on the Plans. Remove septic tanks, cisterns, and cesspools.

Rebuild and reconnect live sewers after removing related manholes, catch basins, and drop inlets. Provide a by-pass and maintain the service during the removal operations. Use concrete or masonry plugs to plug pipes draining into abandoned basements, manholes, or similar Structures. C.4 Timber Structures and Underground Tanks Remove timber Structures and underground tanks in accordance with applicable laws and regulations. C.5 Wells and Borings Refer to Minnesota Rules, Chapter 4725, “Wells and Borings,” for the definition of “wells” and “borings.” Construct and seal wells and borings to meet the requirements of Minnesota Rules, Chapter 4725, “Wells and Borings.” Seal wells and borings taken out of service meeting the requirements of Minnesota Rules, Chapter 4725, “Wells and Borings.” Protect wells and borings until permanently meeting the requirements of Minnesota Rules, Chapter 4725, “Wells and Borings,” during the Work to prevent surface drainage from entering the opening. Cut and remove casing in the well or boring to the elevation as shown on the Plans or as directed by the Engineer after sealing. Submit one copy of the sealing record to the Minnesota Department of Health and one copy to the Engineer within 30 Calendar Days after sealing a well or boring. C.6 Miscellaneous Items When removing railroad tracks, remove rails, ties, paving, crossings, track encasements, and other appurtenances. D Disposal of Materials and Debris D.1 Disposal Plan Provide the Engineer with information and documentation substantiating proper disposal arrangements and operations. The Department will not pay for removal before acceptance of the initial disposal Plan or, if required, a modified disposal Plan. D.2 Disposal Within Right-of-Way Do not dispose of Material or debris within the Right-of-way. Do not burn or bury treated or untreated wood, including but not limited to dimensional lumber, B rush, trees, and roots, within the Right-of-way. D.3 Disposal Outside Right-of-way Dispose of Materials and debris, resulting from removal or demolition operations having no specific disposal provisions, outside the Right-of-way. Assume full responsibility for acceptable disposition of the Material and for damages resulting from the disposal operations. The Engineer may not give final acceptance of the Work:

Contractor's obligations. E Backfilling Depressions Backfill depressions with Material in accordance with 2106, “Excavation and Embankment – Compacted Volume Method.”

2104.4METHOD OF MEASUREMENT

A Area The Engineer will measure pavements, Sidewalks, surfacing, and other uniform thickness items by area without specifying the thickness. The Engineer will classify pavement removal by kind of paving Material when the Material is comprised entirely of Portland cement concrete (remove concrete pavement) or entirely of bituminous-Aggregate mixtures (remove bituminous pavement). If the pavement is comprised of a combination of different paving Materials, such as a concrete base or pavement overlaid with bituminous surfacing, the Engineer will measure the removal of the entire Structure as the unclassified item of “remove pavement.” Regardless of classification, the Engineer will include the removal of integrant curb removed as a part of pavement removal. The Engineer will separately measure the removal of pavement as part of the excavation of trenches for installation of drainage Structures or utility items as the Pay Item for remove trench pavement. Remove trench pavement will include the removal of paving courses including unclassified Materials. B Length The Engineer will measure the length along the longitudinal centerline of the S tructure, parallel to the base or foundation supporting the Structure, and from end to end of the removed Structure. The Engineer will measure pipe from center to center of junction fittings, catch basins, or manholes . The Engineer will include the length of aprons removed as shown on the P lans with the pipe measurements. The Engineer will measure sawing of concrete and bituminous pavements by length along the saw cut lines as staked by the Engineer, if included as Contract Items. C Volume The Engineer will determine the volume of concrete or masonryS tructures by taking measurements on the in-place Structure as it is being uncovered and removed, except if otherwise established. D Number (Complete Unit) The Engineer will measure Contract Items with a Contract “each” price by counting the number of individual units removed, salvaged, or abandoned, including all appurtenances. E Lump Sum The Engineer will measure portions of completed Work.

2104.5BASIS OF PAYMENT

The Contract Unit Prices for remove, salvage, or abandon includes the cost of the following:

ordinances, and regulations The Contract Unit Prices for sawing only includes sawing of concrete and bituminous pavements using a saw. Use of any other method, approved by the Engineer, at the option of the Contractor, will be at no additional cost to the Department. The Department will include the cost of sawing with other relevant Contract Pay Items if the Contract does not include a Contract Pay Item for sawing.

The Contract Unit Price for fence removal includes the cost of removing abandoned fences . The Department will include the cost of removal of abandoned fences with other relevant C ontract Pay Items, if the Contract does not include a Contract Pay Item for fence removal. For salvage items, the Department will only pay for units removed in a condition acceptable for reuse. The Department will include the cost of the necessary removal of damaged or deteriorated units with other relevant removal Contract Pay Items or as Extra Work in accordance with 1402, “Contract Revisions.” If the Contractor’s negligence damages Materials designated for salvage, the Department will deduct from any moneys due or becoming due the Contractor an amount equal to 60 percent of the current delivered price of new Material of the same type and size as that damaged and equal to the quantity of Material so damaged. The damaged Material shall then become the property of the Contractor. The Department will pay for the removal of the ends of old box Culverts preparatory to extending the Structure by the cubic yard or by each unit. The Department will pay for backfilling depressions resulting from the removal of S tructures as embankment construction. The Department will pay for removing pavement and miscellaneousS tructures on the basis of the following schedule: Item No. Item Unit
