Inspection — Protected From Caving In Sec. 94. Where possible, all exca- vations for buildings shall be made at least nine inches beyond the line of masonry ' to permit of inspection, and shall be properly guarded and protected by the person, persons, or corporations causing the same to be made, so as to prevent the same from becoming dangerous to life and limb, and shall be sheath piled where it may be necessary, cr by some other method approved by the Building In- spector, to prevent the adjoining soil from caving in by reason of its own weight or by reason of any weight that may rest upon it. Protection of Adjoining Building — Expense How Borne Sec. 95. Whenever any excavation is made on land adjoining a building, the owner of the land upon which such excavation is made shall shore up, protect and take every precaution- ary measure to protect and save from injury or harm any footings, founda- tions, walls or parts thereof, or any part pf the building, which is liable 13 to occur by reason of such excava- tions, provided the depth of such ex- cavation exceeds three feet below grade. If such excavation does not exceed three feet, then any such ex- pense shall be borne by the owner of such building. Traffic Uninterrupted. Sec. 96. When buildings to be erected or altered front on business thoroughfares and in congested busi- ness districts, the.

Every building except buildings erected upon solid rock, shall have foundations of brick, stone, steel, iron, or Portland cement con- crete laid not less than four feet be- low the surface of the earth, on solid ground on level surface of rock, or upon piles or ranging timbers when solid earth or rock is not found. Piles intended to sustain a wall, pier or post shall be spaced not more than thirty-six nor less than tw T enty- five inches on centers, and they shall be driyen to a solid bearing, if prac- ticable to do so, and the number of such piles shall be sufficient to sup- port the super-structure proposed. Wood piles or posts may be used tinder frame buildings. Where built over water or on meadows land, they must project above the water a sufficient height to be above high tide, and building may be placed directly thereon without other foundation. Providing, however, that such building shall not be over two stories in height, and the posts or piles must be at least five inches in diameter at the small end, and »ot more than eight feet apart. Dimension of Piles. Sec. 98. No pile shall be used of less dimension than five inches at the amall end and ten inches at the butt for piles of twenty feet or less in length, and twelve inches at the butt for piles more than twenty feet in length. No pile shall be weighted with a load exceeding thirty thousand pounds. Sustaining Power of Piles — Piles, How Protected. Sec. 99. When a pile is not driven to refusal, its safe sustaining power shall be determined by the following formula: Twice the weight of the hammer in tons multiplied by the I ! height of the fall in feet divided by least penetration of pile under the last blow in inches plus one. The Building Inspector shall be notified of the time when test piles shall be riven. The tops of all piles shall be cut off below the lowest water line. When required, concrete shall be rammed down in the interspaces be- tween the heads of the piles to a (depth and thickness of not less than I twelve inches and for one foot in width outside of the piles. Capping Timbers. Sec. 100. Where ranging and cap- ping timbers are laid on piles for foundations, they shall be of hard wood not less than si» inches thick and properly joined together, and their tops laid below the lowest water line. Metal in Foundations — Footing Be- low Water Level Sec. 101. Where metal is incor- porated in, or forms part of, a foun- dation, it shall be thoroughly pro- tected from any rust by paint, as- phaltum, concrete, or by such mater- ials and in such manner as may be approved by the Building Inspector. When footings of iron or steel for columns are placed below the water level, they shall be similarly coated, or inclosed in concrete, for preserva- tion against rust. Loads on Caissons Sec. 102. When foundations are carried down through earth by piers of stone, brick, or concrete in cais- sons, the loads on the same shall not by more than fifteen tons to the square foot, when carried down to rock; ten tons to the square foot, when carried down to firm gravel or hard clay; eight tons to the square foot in open caissons or sheet pile 14 trenches when carried down to rock.

Foundation walls shall be built of stone, or brick, with ce- ment mortar, or of Portland cement concrete, except foundations for frame buildings and private stables, and for buildings not more than two stor- ies in height, which may be built with lime and cement mortar. If built of Portland cement concrete, they y shall be at least four inches thicker than the wall next above them in a depth of twelve feet below the curb level, and for every additional ten feet, or part thereof deeper, thy shall be in- creased six inches in thickness. The footing or base course shall be of stone or concrete, or both, or of con- crete and stepped up brick work, of sufficient thickness and area safely to bear the weight to be imposed there- on. Concrete Footings — Stone Footings — Width of Base Course Sec. 104. If the footings or base course be of concrete, the concrete shall not be less than eight inches thick. If of stone the stone shall be of large size, and at least six inches in thickness for walls, and not less than eight inches in thickness for piers, columns or posts. The footing or base course, except under frame buildings, whether formed of concrete or stone, shall be at least eight in- ches wider than the bottom width of walls, and at least six inches wider on all sides than the bottom width of the said piers, columns, or posts. If the superimposed load is such as to cause undue transverse strain on a footing projecting six inches, the thickness of such footing shall be in- creased so as to carry the load with safety, by adding extra course or courses of above dimensions. All base stones shall be well bedded and laid crosswise, edge to edge. Stepped Up Footings If stepped up footings of brick are used in place of stone above the con- crete, the offsets, if laid in single courses, shall not exceed one and one- half inches, or if laid in double cours- es, then each shall not exceed three inches, offsetting the first course of brick work, back one-half of the thickness of the concrete base, so as properly to distribute the load to be imposed thereon. isolated Piers as Supports — Inverted Arches Sec. 105. If, in place of a contin- uous foundation wall, isolated piers are to be ’built to support the super- structure, where the nature of the ground and character of the building make it necessary, in the opinion of the Building Inspector, inverted arches resting on a proper bed of concrete, both designed to transmit with safety the superim- posed loads, shall be placed between the piers.' The thrust of the outer pier shall be taken up by suitable wrought iron or steel rods and plates. Grillage Beams Sep. 106. Grillage beams of wrought iron or steel resting on a proper concrete bed may be used.

All headers shall be at least twelve inches in width, and six inches in thickness, and consist of good flat stones. Stones, How Laid No stone shall be laid in such walls in any other position than on its natural bed. No stone shall be used that does not bond or extend into the wall at least six inches. Stones shall be firmly imbedded in cement mortar and all spaces and joints thoroughly filled. Thickness of External Retaining Walls Sec. 108. External retaining walls shall be constructed of sufficient thickness safely to support the out- side pressure when earth embank- ments are adjacent to any founda- tion or curb wall. Sewer Connections Before Founda- tions Laid Sec. 109. In all cases a connec- tion with the street sewer where the same exists, shall be established be- fore beginning the work of laying foundations. Before the walls of buildings are carried up above the foundation walls, the cellars shall be connected through drain tiles and catch basins with the street sewer. Should there be no sewer in the street, or if the cellars are below the sewer or ground water level, then provisions shall be made to prevent water accumulating in the cellars to the injury of the foundations or the occupancy of the basement cellar.

Thickness Increased For Reduction of Area Sec. 120. When any horizontal sec- tion of wall shows more than twen- y-five per cent, reduction of area on account of flues, openings, and re- cesses, four inches shall be added for every succeeding interval of ten per cent, or part thereof of reduction, provided that in walls of uniform thicknesses, such reduction does not exceed fifty-five per cent, of the wimple, or, in masonry pier construc- tion, not more than seventy per cent, for each bay. Thickness Increased For Heavy Floor Roads . ‘ Sec. 121. When the floors of a building of an established height are to be loaded heavier than the max- imum given in the tables of permis- sible loads, the thickness of walls shall be proportionately increased. Thickness Increased For Additional Length Sec. 122. All buildings over one hundred feet in depth, without a erosswall or proper piers or but- tresses, shall have the side or bearing walls increased in thickness four inches more than is specified in the respective sections of this Code for the thickness of walls for every one limndred feet, or part thereof, that the said buildings are over one hun- dred feet in defth.
