SECTION 3307  PROTECTION OF ADJOINING PROPERTY
Add Sections B-3307.2 through B-3307.8 as follows:
B-3307.2 License to enter adjoining property. The responsibility of affording any license to enter adjoining property shall rest upon the owner of the adjoining property involved. It is the responsibility of the person making or causing construction or demolition operations to obtain any necessary license to enter adjoining property from the owner of such property prior to the start of work. If the person who causes the construction, demolition, or excavation work is denied a license to enter by the adjoining property owner, and the building undergoing work is an imminent danger to the adjoining property, as determined by the Department, such duty to preserve and protect the adjacent property shall devolve to the owner of the adjoining property.
   B-3307.2.1 Notification. Where a construction or demolition project will require access to adjoining property, in order to protect the adjoining property or otherwise, written notification shall be provided to the adjoining property owner a minimum of 10 days prior to the commencement of work. Such notification shall describe the nature of work, estimated schedule and duration, details of monitoring to be performed on the adjoining property, protection proposed to be installed on the adjoining property, and contact information for the project.
B-3307.3 Physical examination. A physical examination of such adjoining property shall be conducted by the person causing the construction or demolition operations prior to the commencement of the operations and at reasonable periods during the progress of the work. Observed conditions shall be recorded by the person causing the construction or demolition operations, and such records shall be made available to the Department upon request.
B-3307.4 Soil or foundation work affecting adjoining property. Whenever soil or foundation work occurs, regardless of the depth of such, the person who performs or causes such work shall, at all times during the course of such work and at his or her own expense, preserve and protect from damage any adjoining structures, including but not limited to footings and foundations.
   B-3307.4.1 Additional safeguards during excavation. The person causing the excavation shall support the vertical and lateral load of the adjoining structure by proper foundations, underpinning, or other equivalent means where the level of the foundation of the adjoining structure is at or above the level of the bottom of the new excavation.
   B-3307.4.2 Preconstruction survey. No excavation work to a depth of more than 5 feet (1524 mm) within 10 feet (3048 mm) of an adjacent building shall commence until the person causing an excavation to be made has documented the existing conditions of all adjacent buildings in a preconstruction survey. Preconstruction surveys shall be maintained by the contractor and made available to the Department upon request.
B-3307.5 Underpinning. Whenever underpinning is required to preserve and protect an adjacent property from construction, demolition, or excavation work, the person who causes such work shall, at his or her own expense, underpin the adjacent building.
B-3307.6 Construction loads supported by existing party walls. The structural adequacy of existing party walls shall be examined by a registered design professional where any construction or demolition work requires the placement of construction materials or equipment upon an existing building or structure supported by the party wall. Any such party wall found through examination to be in an unsafe or imminently dangerous condition as defined by the Philadelphia Property Maintenance Code shall be immediately reported to the Department. Any party wall found through examination to be structurally inadequate to support proposed construction loads shall be strengthened in an approved manner prior to the placement of any construction loads.
   B-3307.6.1 Support of party walls. Where a party wall will be affected by excavation, regardless of the depth, the person who causes the excavation to be made shall preserve such party wall at his or her own expense so that it shall be, and shall remain, in a safe condition. Where an adjoining party wall is intended to be used by the person causing an excavation to be made, and such party wall is in good condition and sufficient for the uses of the existing and proposed buildings, it shall be the duty of the person excavating to protect the party wall and support it by proper foundations, so that it remains insofar as possible as safe as it was before the excavation was commenced.
B-3307.7 Interior walls exposed after demolition. Interior walls that become exterior walls as the result of a demolition shall comply with Chapter 14 of the Building Code. All cornices, where cut shall be sealed. All loose material shall be removed, and all voids shall be filled with a suitable material. Such walls shall have wall coverings installed that comply with the applicable provisions of Chapter 14 of the Building Code. The walls shall be carefully examined by a competent person designated by the permit holder to ascertain the condition and adequacy of the party wall to accept the required wall covering. Wall covering to be installed on a wall shall not be more than the wall is capable of safely supporting. Where the Department determines that a wall is incapable of supporting any acceptable wall covering and has issued a related violation, such wall shall not be required to be covered until the violation is corrected.
The exterior of foundation walls that enclose interior space of a structure adjoining a structure that has been demolished shall be damp-proofed in accordance with Chapter 18 of the Building Code prior to backfilling. The person responsible for the demolition shall be responsible for compliance with this regulation.
B-3307.8 Protection of roofs. Whenever any building is to be constructed or demolished above the roof of an adjoining building, it shall be the duty of the person causing such work to protect from damage at all times during the course of such work and at his or her own expense the roof, skylights, other roof outlets, and equipment located on the roof of the adjoining building, and to use every reasonable means to avoid interference with the use of the adjoining building during the course of such work.
Adjoining roof protection shall be secured to prevent dislodgement by wind. Where construction or demolition work occurs at a height of at least 48 inches (1219 mm) above the level of the adjoining roof, adjoining roof protection shall consist of 2 inches (51 mm) of flame-retardant foam under 2 inches (51 mm) of flame-retardant wood plank laid tight and covered by flame-retardant plywood, or shall consist of equivalent protection acceptable to the Department, and shall extend to a distance of at least 12 feet (3658 mm) from the edge of the building being constructed or demolished.
