   (i)    Unless the contract or orders of the City provide otherwise, total removal of the structure to the actual building and property line.

   (j)    Provision of proper drainage in the subsoil conditions. Percolation shall be provided in basement slabs by breaking or by drilling holes through the slabs, approximately six feet on center in all directions and connecting drain tile into existing storms where necessary for proper drainage. All floor slabs, under which a pit, well, cistern, tank or void exists, shall be broken or removed. All drains not removed shall be sealed with masonry or with precast clay or concrete stoppers.

   (k)    Complete removal from the demolition site of all organic materials, including wood, plastics, old plaster, floor tile and similar rubble. Masonry, stove concrete, tile bank-run gravel and compacted earth are permitted fill materials.

   (1)    Adjoining and party walls, as follows:

      (1)    If one of two back to back or adjoining walls, each of which is built along a common property line of two different ownerships, is required by order to be demolished with the rest of the structure, the contractor shall be responsible for the adjacent or adjoining property wall for repair of defects occasioned by the contractor, to the extent that the same shall be repaired or reconditioned as needed with suitable construction materials and procedures to insure that such remaining wall is as free from defects, and safety, fire and health hazards as it would have been had the wall not been demolished.

      (2)    Where the back to back or adjoining wall of the structure to be demolished is not required to be demolished, the contractor shall insure that such wall does not create or constitute a health, fire or safety hazard. When such wall exposes a variety of materials such as brick, stone, plaster or block, a cement or latex paint specifically prepared for masonry walls shall be applied to such exposed surface; provided that other means may be utilized when prior approval of the means has been granted by the Bureau.

      (3)    The contractor shall insure that party walls are structurally sound and do not create or constitute a health, fire or safety hazard. When such party wall exposes a variety of materials such as brick, stone, plaster or block, a cement or latex paint specifically prepared for masonry walls shall be applied to such exposed surface; provided that other means may be utilized when prior approval of the means has been granted by the Bureau.

   (m)    Insuring that any remaining walls, whether adjoining, party or back to back, have all openings, crevices, gaps, fissures, joist slots and the like plugged and carefully tamped or sealed with some suitable material against the weather, elements, fowl, rodents and other wildlife, so as to render them free of health, safety and fire hazards.

   (n)    Maintaining established property lines and grades at the original lines and grades. Backfill when necessary shall include structures suitable to retain the original grades. Where vertical walls have been removed from stone retaining walls, such retaining walls may be retained if suitable backfill is provided to furnish sufficient side load to retain the original support of the property. The premises shall be graded to prevent water from unnecessarily draining onto adjacent premises.

   (o)    Construction of damaged or destroyed curbs, gutters and sidewalks with new four-inch concrete improvements in accordance with City specifications.

   (p)    Filing with the City Engineer a sketch plan of any foundations, walls or other pertinent data relating to the site which have been buried by backfill.
