Standard Specifications 



KjCnCTai All tile to carry approxi- 
mately 300 lbs. per square foot breaking 
load, uniformly distributed when resting on 
supports spaced the same as the purlins. No 
cracked or broken tile or tile with broken 
corners or warped tile will be permitted to be 
placed in the roof. All tile to be as nearly 
perfect as good workmanship will permit. 
All tile to be natural water and air cured 
under cover where a constant temperature is 



Interlocking Tile 



The Pitched Roof is to be Pre-Cast Reinforced Con- 
crete Tile, Interlocking Type, with the necessary 
trimmings, to make a complete and satisfactory job. 

All tile to be composed of an approved brand of 
Portland Cement and the highest grade of washed 
torpedo sand, in a mixture of one part of cement to 
2/€ parts of sand accurately graded and thoroughly 
mixed and mechanically tamped and kneaded, so as 
to obtain the greatest possible density and water- 
tightness. Each slab is to be reinforced with a sheet 
of galvanized cold drawn wire mesh, the longitudinal 
wires spaced not more than 2" apart and crosswires 
woven around the longitudinal wires. 

The sheet of mesh reinforcing shall be mechanically 
straightened before being placed in the slab so that 
it can be accurately centered in a plane and be pro- 
tected by a half-inch of dense impervious concrete. 

The exposed surface of the tile to present a perma- 
nent red color and this color, a mixture of iron oxide 
and cement, to penetrate the top one-half of the 
slab. The top surface to be thoroughly troweled 
giving same a smooth and uniform finish. 

The longitudinal joints to be of plastic made with a 
high-grade oil cement and a weather cap coat of 
highest grade elastic compound. The joint to con- 
form to detail shown on the drawings. 

The lap or cross joint to be formed of a high-grade 
oil cement. Butter the upper end of each course 
of tile as laid, then install course above producing 
a squeeze joint at over-lap. 

Special tile to be furnished where necessary; these 
tile to be detailed and manufactured to interlock and 
fit in with adjacent tile without field cutting. 



Qlass Tile 



Top lighting shall be provided by Pre-Cast Re- 
inforced Concrete Tile with Glass Inserts. Locate 
as shown on the drawings. These tile are to be 
made so as to be interchangeable with the standard 
52" Interlocking Tile. 

The mix, material and workmanship of these tile 
shall be the same as the Standard Interlocking Tile. 

A sheet of }£' wire-glass 21"x35" is to be imbedded 
in the concrete during the process of anmufacture 
of the tile, thus becoming an integral part thereof. 



maintained of not less than 60 degrees Fahr. 
This contractor shall make up and submit 
for approval pre-cast slab details based on 
the steel fabricator's shop drawings as well 
as the architect's design drawings, before 
starting manufacture of material. 

All tile are to be erected by the manufacturer 
furnishing the material in a thorough work- 
manlike manner. 



The four edges of the glass are to be triple dipped in 
a special asphalt compound, forming a cushion on 
all four sides, to allow for expansion and contraction. 

A condensation gutter and weep hole formed in the 
concrete at the lower edge of glass is to be an integral 
part of the glass tile. 



Flat Slabs 



The flat roof decks and gutters are to be Pre-Cast 
Reinforced Concrete Flat Slabs, 24" wide, of a 
length to fit purlin spacing and not less than I $4" 
thick for the standard 5 ft. 0" slabs, composed of 
an approved brand of Portland Cement and the 
highest grade washed torpedo sand in a mixture of 
one part of cement to 2% parts of sand accurately 
graded, thoroughly mixed, tamped and kneaded so 
as to obtain the greatest possible density. Each 
slab is to be reinforced with a sheet of cold drawn 
wire mesh, the longitudinal wires of which shall be 
spaced not more than 2" apart and cross-wires 
woven around the longitudinal wires. 

The under side of the tile shall present a smooth 
surface free from cracks or form marks, and shall be 
of a uniform natural gray cement color. 

All joints of the fiat slabs are to be cemented on the 
upper side with an approved brand of asphaltic 
cement and present a smooth surface ready for the 
application of the composition covering. 



Channel Slabs 



The flat roof decks are to be Pre-Cast Reinforced 
Concrete Channel Slabs 18" wide and 3<y£" 
deep and a maximum length of 96" the web 
thickness to be a full one inch, composed of an 
approved brand of Portland Cement and the highest 
grade of washed torpedo sand in a mixture of one 
part of cement to three parts of sand accurately 
graded and thoroughly mixed and vibrated so as to 
obtain the greatest possible density. Each 3$4" 
leg is to be reinforced with one deformed bar accur- 
ately centered so as to have at least one-half inch 
of dense, impervious concrete on all sides. The 
web of the slab is to be reinforced with a sheet of 
triangular cold drawn wire mesh accurately centered. 

All joints of the channel slabs are to be cemented on 
the upper side with an approved brand of asphaltic 
cement and present a smooth surface ready for the 
application of the composition covering.
