No. 1. - In. order that the student may ascertain to what extent he is grasping the situation, at this point, and before proceeding further with this specification, he should spend at least six hours on masonry work in progress in his vicinity, observing work which corresponds to that referred to in this outline specification. He should ask questions of such foremen or workmen as he is able to approach, regarding the details of coustruction and materials used. He should see the men who furnish the material, and obtain from them the prices, and also find if there are different grades thereof.
Under no circumstances are notes to be taken. The student is to get the information in mind in such a way that he will remember it. After the conclusion of these investigations, he should allow four days to elapse, during which time he is to think over the situation as observed. After the four days of thinking, he should write a specification not exceeding 400 words in length, covering some portion of the work or materials observed, and giving special attention to covering the most ground possible with the 400 words.
All furring terra-cotta is to be set in Portland cement mortar. As 1 to 4 mixture would be too short for the thin edges, the mortar will be 1 cement to 2 1/2 sand; and one 30d-spike is to be driven into the brick mortar joints, with head projecting 1 1/2 inches into furring joint for tie.
All joints are to be 1/2 inch thick; and the special anchors shown on the detail are to be built in. Fill all hollow portions with concrete formed by filling in with cement mortar and then crowding in broken bricks until the mortar is forced into every corner.
Over all approximately horizontal surfaces, put a 1/2-inch coat of Portland cement mortar, 1 part cement to 1 part sand, after covering the surface with a continuous sheet of No. 24 expanded metal. The terra-cotta surface is to be thoroughly wet, the mortar coat pressed vigorously through the metal, and the surface finished smooth. This surface it to be protected from the sun for four days, and wet at such intervals as will keep it at all times moist.
