Existing laws, ordinances, and regulations govern the parking, loading, and operation of trucks on existing highways or streets. The Department assumes no responsibi lity for the condition of the v arious buildings or loss of fixtures, equipment, materials, or other objects between the submittal of the Proposal and the time of actual possession of the buildings. On a daily basis, remove and dispose of, as specified in 201.03.01.H, materials, including fixtures, equipment, debris, and rubbish, and do not store removed materials within the Project Limits. Do not sell materials within the Project Limits. Where others have removed buildings, arrange to disconnect and terminate remaining utility services. Remove foundation walls and steps to at least 3 feet below ground level. Remove detached buildings and fixtures, wood, and debris from the site and dispose of as specified in 201.03.01.H. Remove heating oil tanks according to N.J.A.C. 7:14B and N.J.A.C. 7:26E, and Federal, State, and local laws, rules, and regulations. Confine demolition operations to the limits shown, and perform work as specified by the following:
1.Demolition Safety Plan. Submit a Demolition Safety Plan to the RE for approval, 10 days before demolition. Include the following provisions in the plan:
a.Type and location of warning signs, KEEP OUT signs, and barricades.
b.Type and location of barrier around operations and openings in the ground.
c.Type and location of lights and footway shelter platforms in the vicinity of pedestrian walkways.
d.Methods for controlling dust from demolition operations. Follow the Demolition Safety Plan until the RE approves the removal of protective devices. For demolition of buildings having more than 3 floors, submit an additional plan to the RE for approval at least 10 days before beginning demolition. Include the demolition methods to be used and methods of protecting adjacent building and structures.
2.Utility Disconnections. Before demolishing any building, arrange to disconnect and terminate all utilities and facilities that are connected to the building, as specified by the municipalities and companies owning or controlling them. If only a portion of an occupied structure is to be demolished, conduct demolition and related operations so that service is not interrupted to the portion of the structure that is not demolished. Where it is necessary to reconnect any facilities to the undemolished portion of the structure, make reconnections permanent. Notify, in writing, the municipalities and companies concerned when such disconnections, terminations, or reconnections are required and provide copy to RE. Perform this work according to the municipalities and companies standard practices and requirements and under their supervision; otherwise arrange for the work to be performed with their forces.
3.Rodent Control and Extermination. Before beginning demolition operations, retain a qualified sanitation inspector to conduct a survey for evidence of current rodent activity. Initiate a control program by a certified pest control operator if the survey indicates that it is necessary. Apply exterminating materials according to N.J.A.C 7:30, et seq. At least 10 days before beginning demolition of any structures, ensure the pest control operator begins ridding the structure and adjacent areas within the Project Limits of rodents or their carcasses and prevent s their migration to other adjacent areas. Where there is no competing water supply, the Contractor may use liquid anticoagulant baits at the discretion of the certified pesticide applicator. Place toxic bait in the form of a 1 pound paraffinized block in each manhole or inlet of storm or combination drains located on the same street as the building to be demolished and within the same block, including the entire intersections of the nearest cross streets. Place bait in suitable locations within the draina ge structures, as determined by the pest control operator. Fasten the bait block in its location with wire. Inspect and renew toxic bait in structures or drains as necessary after initial baiting. Remove and dispose of carcasses to the satisfaction of the RE. After the initial treatment and each follow -up inspection, submit a signed statement, from the pest control operator, reporting the amount and type of bait placed in each location and stating the visible results obtained from the rodent control program. Ensure that the pest control operator is aware of the antidote noted on the rodenticide label.
4.Demolition Operations. Before demolishing buildings, remove and dispose of chemicals, miscellaneous cylinders, drums, above ground and underground heating oil tanks per NJDEP Unregulated Heating Oil Tank Program, asbestos, and garbage from the building according to applicable Federal, State, and local laws, rules, and regulations. Remove and recycle materials that are required to be recycled by the Federal, State, and local laws, rules, and regulations. Before beginning d emolition operations, pump out and clean basements, wells, cesspools, and outbuildings within the areas to be cleared in a sanitary manner. After being disinfected as required by the health authorities, backfill to adjacent ground level as specified in 201.03.07.5. Maintain wells, cisterns, cesspools, and other openings in the ground outside the area to be cleared without hindering their functionality. Cap well casings securely and permanently as specified in 201.03.06, and cutoff and cap pipes leading into or out of the well. Leave adjacent buildings in a safe condition, and do not deface, mar, or jeopardize them in any way. Repair or restore damaged buildings to the satisfaction of the RE. Ensure that the phases of demolition are performed within the designated limits and without hazard to adjacent properties or to the public. Do not set any structure on fire. Do not demolish or di sturb chimneys common to adjacent properties other than to give them the necessary support for their continued stability. If necessary, repoint and cap them. When demolishing a portion of a building, shore, brace, and support the remaining part so that the integrity and support of all remaining walls, floors, roofs, and their supporting members are maintained and continued in such a way that shoring, bracing, and support is outside the ROW. Board up and seal the remaining portion of such a partially demolished building along the ROW, and weatherproof the new closure and its connections to the remaining portion of the severed building. Ensure the material for closure consists of adequately braced studding of 2 4 inch timbers placed no more than 16 inches on center with wood facing nailed to the studding without any holes appearing therein. Cover the wood facing with 2 layers of smooth -finished, 65 pounds per roll, roofing material according to ASTM D 224 and having an overlap of at least 4 inches.
5.Backfilling. Backfill and compact subsurface areas including cellars using the directed method as specified in
203.03.02 B.3. The RE may require compaction using the density control method as specified in 203.03.02.B.4.
Use all available excavated material from within the Project Limits before bringing additional material for backfill to the Project Limits. If sufficient material is not available, backfill with I -14 soil aggregate. If excavated material or I-14 soil aggregate are recycled material, place the recycled material at least 2 foot above the water table. Ensure backfilling and grading establishes proper drainage. Before placing the first lift, break existing cellar floors and other surfaced areas into pieces having areas of less than 4 square feet with well -defined cracks through the full depth of the floors, or make holes of more than 1 square foot area through the floors on approximately 10 foot centers to provide vertical drainage. Remove wooden cellar floors. Clean, point, and apply 2 coats of waterproofing material to party wall foundations before backfilling against. If necessary, grade around the ground surface to eliminate water pockets. Backfill and level cellars and all other subsurface spaces to the adjacent ground elevation.
201.03.08 Removal of Asbestos
Refer to the Special Provisions for asbestos removal requirements.
201.03.09 Temporary Shielding
Submit working drawings for certification for a sy stem to protect vehicular, pedestrian, or railroad traffic or environmentally sensitive areas from falling debris, construction materials, or other objects. Temporary shielding requirements are in addition to forms and falsework required for construction. Design the temporary shielding system to conform to the following:
1.Withstands loads of at least 0.8 pounds per square inch, or greater if heavier loads are anticipated or if required by railroads.
2.Prevents small particles and dust from escaping the shield.
3.Seals the underside of the deck and extends outside of the deck and outside of the fascia stringers to enclose the soffits and parapets.
4.If parapet removal or parapet construction is required, provide an outrigging to enclose the soffit and parapet.
5.Does not bolt or weld the temporary shielding system to the beams.
6.Does not reduce the underclearance of the bridges to less than 14.75 feet over roadways and 22 feet over railroads or as specified in the Contract. If existing underclearanc e is less than these values, does not further reduce the underclearance. Show elements of the temporary shielding system, including design calculations, and the sequence of operations, and, when applicable, bonding and grounding over electrified rail lines. Include with the working drawings a plan for removing material, dust, or debris that has fallen into active traffic lanes, railroads, and environmentally sensitive areas. Install the temporary shielding according to the certified working drawings before performing any construction operations over vehicular, pedestrian, or railroad traffic or ecologically sensitive areas. The RE will not allow the installation of temporary shielding over active traffic lanes and pedestrian areas. When app licable, comply with the railroad’s maintenance of traffic requirements, rules and regulations. Remove and reinstall the temporary shielding as required by construction staging. Do not allow dropped materials to accumulate on the temporary shielding, and remove dropped materials promptly. If debris falls from the shielding, promptly clean it up and repair the damage.
