      NAC 452.010  “Class A construction” defined.  As used in this chapter, a

“Class A construction” means a building for which the stress of all external or

internal loads or strains is transferred to the foundation by a reinforced

concrete frame or by a skeleton or framework of steel, and the columns, beams

and girders are riveted to each other at their respective junctures. Buildings

not more than 25 feet in height and constructed of granite or marble will be

considered Class A construction when they fulfill the provisions of this

chapter.

     [Bd. of Health, part Mausoleum Reg., eff. 7-5-32]

      NAC 452.020  Construction of mausoleums: General requirements.  No

building or structure for use or intended to be used for the permanent

interment of the remains of deceased persons may be constructed, and no

building now constructed but not used for the permanent interment of the

remains of deceased persons may be altered or changed for such a use unless

constructed of such material and workmanship as will ensure their durability

and permanence.

     [Bd. of Health, part Mausoleum Reg., eff. 7-5-32]

      NAC 452.030  Class A construction required.

     1.  All mausoleums or columbariums

constructed after July 5, 1932, must be of a Class A construction.

     2.  All footings, bearing walls, beams,

columns, floor slabs and other structural elements must be designed and constructed

with a safety factor of four.

     3.  All floors must be designed for a live

load of at least 100 pounds per square foot.

     [Bd. of Health, part Mausoleum Reg., eff. 7-5-32]

      NAC 452.040  Footings.  Footings

for any mausoleum or columbarium erected after July 5, 1932, must be made of

concrete and reinforced with steel.

     [Bd. of Health, part Mausoleum Reg., eff. 7-5-32]

      NAC 452.050  Loads.

     1.  All live and dead loads in a mausoleum or

columbarium must be supported by the walls of columns connected directly to the

footings.

     2.  The total load on footings may not exceed

the safe soil bearing as determined by testing.

     3.  Footings must be designed for total

loads, but relative sizes of footings must be governed by the dead loads only,

with a proper reduction of the allowable soil-bearing value.

     4.  A crypt must be designed for a total load

of 600 pounds. Such a load must be considered as a live load for the purposes

of subsection 3.

     5.  Possible stresses from earthquakes must

be considered in all structural designs.

     [Bd. of Health, part Mausoleum Reg., eff. 7-5-32]

      NAC 452.060  Walls.

     1.  The wall of a mausoleum or columbarium

which supports a load and is erected after July 5, 1932, must be constructed

     (a) Concrete;

     (b) Cut stone;

     (c) Cast stone;

     (d) Granite; or

     (e) Marble.

     2.  All of the materials must be reinforced,

anchored and supported in such a manner as to ensure an enduring and lasting

structure.

     3.  In any new building or in any alteration

or addition to any existing building which is used for the permanent interment

of the remains of deceased persons and which is constructed after July 5, 1932,

all bearing walls must be made of granite, marble or reinforced concrete. If the

building exceeds 25 feet in height, bearing walls must be made of reinforced

concrete.

     4.  If any wall is constructed against a bank

of earth, rock or other porous material, the exterior face of the wall above

the footing must be thoroughly and efficiently waterproofed before backfilling

is completed.

     [Bd. of Health, part Mausoleum Reg., eff. 7-5-32]

      NAC 452.070  Anchors.

     1.  Fastenings on hangers, clasps, clips,

wires and doors and other fasteners must be made of brass, aluminum or copper

of at least 22-gauge copper-bearing iron or steel.

     2.  The base, architraves, wainscoting and

all other vertical work must be securely clamped to the backing with rods and

heavy wire clips or other anchoring devices made of materials listed in

subsection 1.

     3.  All case clips must be countersunk into

the surface of a joint and set in plaster.

     [Bd. of Health, part Mausoleum Reg., eff. 7-5-32]

      NAC 452.080  Settings.

     1.  Marble in a floor must be set in a full

bed of nonstaining cement mortar, the proportion of cement to sand to be one to

two, and tamped to a uniform bearing true to line.

     2.  All stone must be tamped to a uniform

bearing true to line and set on an even bed of mortar. Lug sills and similar

work exposed to uneven pressure must be bedded only at the ends.

     3.  Mortar joints must be of uniform

thickness not more than three-sixteenths of an inch and must be raked out to a

depth of three-quarters of an inch as the work progresses.

     [Bd. of Health, part Mausoleum Reg., eff. 7-5-32]

      NAC 452.090  Mortar.  The

mortar for setting all stonework must be composed of at least one part

nonstaining Portland cement to three parts of clean, white, coarse sand,

tempered with lime putty.

     [Bd. of Health, part Mausoleum Reg., eff. 7-5-32]

      NAC 452.100  Pointings.  After

stonework is completed, all joints must be brushed, cleaned thoroughly, wet and

carefully filled with mortar, solidly packed and pointed. Mortar for pointing

must be composed of one part lime putty, two parts white Monterey sand or its

equivalent, and two parts nonstaining Portland cement.

     [Bd. of Health, part Mausoleum Reg., eff. 7-5-32]

      NAC 452.110  Bed joints.  All

work which may have projecting parts must have sufficient bearing on the walls

to balance independent of anchors.

     5.  Sills must extend at least 3 inches back

of the windowsill and must have a fillet to receive the sills.

     6.  All veneering must be anchored by placing

anchors with a 1/4-inch diameter at the top of each stone. These anchors must

     5.  In mausoleums where air ventilation is

used and crypts are situated adjacent to the wall of an outside building below

the ground, an air space at least 18 inches wide must be provided between the

outside wall and the walls of the crypt. The air space must be supplied with
