Article 2. Structural And Material Requirements Of Community Mausoleums And Columbariums of California Health And Safety Code >> Division 8. >> Part 5. >> Chapter 5. >> Article 2.

Every mausoleum or columbarium shall be designed and constructed to conform to the earthquake provisions of the Uniform Building Code.

Except as otherwise provided in this chapter, all materials used in the construction, ornamentation, or embellishment of mausoleums or columbariums shall be incombustible. This section shall not apply to crypt vents, temporary openings or partitions, interior doors, fixtures, furniture, or furnishings.

All structural framework shall be of cast-in-place reinforced concrete, or of structural steel sections, or of concrete over metal decking; provided, however, all footings, bearing walls, floor slabs and roofs shall be of cast-in-place reinforced concrete or of concrete over metal decking only. All structural framework shall be designed and constructed in accordance with the Uniform Building Code.

All floors shall be designed and constructed for a live load of not less than 100 pounds per square foot.

Footings shall be designed and constructed to conform to the requirements of the Uniform Building Code or specifications of a licensed geotechnical engineer.

Floor slabs placed on earth shall be constructed of reinforced concrete designed by a licensed structural or civil engineer to include control joints at appropriate intervals to minimize cracks as well as appropriate vapor and moisture barriers as specified by a licensed geotechnical engineer.

Where any wall is constructed against a bank of earth, rock, or other porous material, or where crypts are adjacent to an outside building wall below grade, the wall shall be adequately waterproofed. Before backfilling, a waterproofed wall shall have a protection board placed against it to prevent damage to the waterproofing during backfilling.

Except as provided in Section 9633, all crypt walls and crypt floor slabs shall be constructed of cast-in-place, reinforced concrete; crypt walls shall conform to structural design but shall be not less than three and one-half inches in thickness, and crypt floor slabs shall be not less than three inches in thickness.

Horizontal and vertical partitions separating crypts comprising companion crypts or a nest of crypts entered through a single crypt opening may be constructed of precast reinforced concrete; provided, the horizontal partitions are not less than one and one-half inches in thickness and the vertical nonbearing partitions are not less than one inch in thickness, and vertical partitions bearing any load are not less than three inches in thickness, and provided the crypt walls enclosing the nest of crypts are constructed as required in Section 9632. Crypts shall be vented at roof level of the structure, and vents shall continue to a gravel filled trench below the floor of the bottom crypt to provide adequate circulation of air. Nonstructural horizontal and vertical partitions separating columbarium niches may be constructed of precast reinforced concrete or other incombustible material.

Each crypt, including each crypt in a companion crypt or in a nest of crypts referred to in Section 9633, shall be designed for a total live load of 600 pounds.

(a) All individual crypt openings shall be sealed with a solid panel of precast concrete, not less than 1 1/2 inches thick, fiber reinforced cement board not less than 7/16 inch thick, or other incombustible material that meets all of the following requirements:
  (1) A minimum density of 80 pounds per cubic foot.
  (2) A minimum modulus of rupture of 270 pounds per square inch.
  (3) A minimum compressive strength of 2500 pounds per square inch.
  (4) A rating that conforms to Underwriters Laboratories fire hazard class 1.
  (b) All panels shall be securely set in with a high quality, nonflammable, resilient, and nonhardening urethane, silicone base, or other appropriate sealant for permanent sealing after interment is made in the crypt. Seal panels shall be set independent of crypt fronts.

All marble floors shall be constructed on a bed of mortar or mastic placed on the floor subslab, with an approved additive to retard efflorescence.

All interior or exterior veneers shall be of stone, cast stone, granite, travertine, or marble, or other material allowed in the Uniform Building Code for type I construction. Cast stone shall meet all requirements for cast stone set forth in the Uniform Building Code.

Material for exterior trim, including exterior crypt and niche fronts, shall be travertine, serpentine marble, or grade A exterior type marble or granite, only.

Joints shall be of uniform thickness and when mortar is used it shall be raked out as work progresses and on completion of installation joints shall be brushed, thoroughly cleaned, wet and carefully filled and pointed.

Grout used for joints and pointing shall conform with the requirements of the Uniform Building Code.

Masonry veneer shall be attached to the supporting wall in accordance with the requirements of the Uniform Building Code.

All base, architraves, wainscoting and all other vertical work other than crypt fronts shall be securely anchored in place with rods, clips, or other suitable anchoring devices of materials as specified in Section 9643. All clips shall be countersunk into the joint surface and set in nonstaining cement or epoxy.

All interior and exterior fastenings for hangers, clips, doors, and other objects shall be of copper base alloy, aluminum, copper or stainless steel of adequate gauges and shall be installed to meet or exceed the seismic requirements of the Uniform Building Code.

All exterior materials used for doors, window frames, skylights, gutters, downspouts, flashings or embellishment shall be of copper, copper base alloy, aluminum, stainless steel, or other corrosion resistant material of gauges structurally determined.

In the event that during a national emergency, as proclaimed by the Governor for purposes of this section, none of the materials listed in Sections 9643 and 9644 are obtainable, the department may permit the use of galvanized iron or other durable materials.

Roofs shall be constructed of cast-in-place reinforced concrete, and any roof covering shall be "Fire Retardant" in conformity with the requirements of type I construction.

All skylight frames shall be fabricated in conformance with structural requirements, and shall contain wire glass, tempered glass, or plastic of comparable strength and durability.
