within ten days after the service thereof, or within such shorter time as the Board may designate, then such order may be executed by said Board through its officers, agents, employees or contractors.


INFECTED AND UNHABITABLE HOUSES TO BE VACATED


b. Whenever it shall be certified by an Inspector or Officer of the Board of Health that a tenement house, or any part thereof, is infected with con- tagious disease, or that it is unfit for human habitation, or dangerous to life or health by reason of want of re- pair, or of defects in the drainage, plumbing, ventila- tion, or the construction of the same, or by reason of the existence on the premises of a nuisance likely to cause sickness among the occupants of the house, the Board may issue an order requiring all persons therein to vacate such house, or part thereof, within not less than twenty-four hours nor more than ten days, for reasons to be mentioned in said order. In case such order is not complied with within the time specified, the Board may cause the tenement house, or part thereof, to be vacated. The Board, whenever it is satisfied that the danger from said house or part thereof has ceased to exist, or that it is fit for human habitation, may revoke said order, or may extend the time for complying with the same.

MASONRY AND WALL CONSTRUCTION SECTION 13


(1) Construction. a. Protection against freez- ing. No masonry shall be built when the temperature


164


ARLINGTON TOWN REPORT


is below 28º F. on a rising temperature, or 32º F. on a falling temperature, at the point where the work is in progress. No frozen materials shall be built upon. Lime shall not be used in any mortar in freezing weather in excess of ten percent of the cement content.


b. Wetting brick. Bricks shall be thoroughly wet just previous to being laid, except in freezing weather, when they shall be thoroughly dry.


c. Erection of walls and piers. Masonry building walls and piers shall be built to a line and carried up plumb. In each story, the walls shall be carried up full thickness to the top of the beams above. No wall of any building shall be built up more than two stories in advance of any other portion of the walls of the build- ing, provided that where walls are carried indepen- dently by beams or girders at each floor, this provision shall not apply. All walls meeting at an angle shall be securely toothed and bonded together, or shall be thoroughly tied together at vertical intervals of five feet by two by one-half inch or larger painted steel or iron ties at least three feet long.


d. Piers. All piers shall be built of stone, con- crete, or good hard brick laid in cement mortar. Every pier supporting any beam, girder, arch, lintel, or column shall have a cap or a cast iron plate when necessary to properly distribute the load. Isolated piers, when un- supported laterally by earth, shall not exceed in height twelve times their least dimensions. The use of mono- lithic stone posts for the support of columns, girders, or walls, is prohibited unless their lengths are less than twice their minimum thickness.


e. Timber in walls. No timber except lintels provided for elsewhere in this Section and nailing blocks not over eight inches long or nearer together than two feet shall be placed in any masonry wall.


165


TOWN RECORDS


(2) Brick masonry. All brick work shall be laid with full mortar joints in-


a. English or modified English bond, having at least every eighth course a full bearing course of whole brick.


b. Flemish bond, having at least every fourth


course of whole brick headers alternating with stretchers throughout the course.


Running bond of face brick, having at least c. every eighth course of alternate full headers and stretchers.


(3) Substitute wall. All walls called for in this By-Law to be of brick may be of Portland cement, con- crete, or other equally substantial approved fireproof material, and, on approval of the Building Inspector, such substitute walls, when called for to be twelve inches thick, may for the upper story be eight inches thick.


(4) Stone masonry. a. Workmanship. No stone shall be laid in a wall in any other position than on its natural bed. Stones shall be firmly bedded in mortar with all spaces and joints thoroughly filled. No stone shall be used that does not bond or extend into the wall at least six (6) inches.


b. Bond. All stone walls twenty-four inches or less in thickness shall have at least one header extending through the wall in every three feet in height from the bottom of the wall and in every three feet in length and, if over twenty-four inches thick, shall have one header for every six superficial feet on both sides of the wall, laid on top of each other to bond together and running into the wall at least two feet. All headers shall be at least twelve inches in width and eight inches thick and consist of sound flat stones.


c. Limitations. Walls built of squared stones with dressed level beds shall have a thickness not less


166


ARLINGTON TOWN REPORT


than that required for brick walls under similar condi- tions. Walls built of rubble stone shall have a thick- ness at least four inches more than required by para- graphs b and c, but no such wall shall be less than eighteen inches thick, and except for foundations, shall not be used in buildings over forty feet high, or in foundations of buildings over sixty feet high.


(5) Hollow block masonry. a. When permitted. Hollow building blocks either of well-burned terra cotta with at least one-half inch shells and webs or of Portland cement concrete may be used for walls except party and fire walls exceeding three stories or forty feet in height, provided that such blocks have met the test requirements of this By-Law and are not stressed beyond the safe limits prescribed herein. The minimum thickness for such walls shall be as required for brick walls. All building blocks shall be laid in Portland cement mortar.


b. Furring. Where hollow blocks of any kind are used as furring for walls, they shall not be included in the measurement of the thickness of such walls.


c. Hollow brick. The inside four inches of walls may be built of hard-burned hollow brick of the dimen- sions of ordinary bricks properly tied and bonded into the walls.


d. Concrete blocks. Concrete blocks shall not be used in construction until they have obtained an age of twenty-eight days, and shall have developed an average of 1000 lbs. ultimate compressive strength per square inch of gross cross sectional area of block as used in wall, and shall not fall below 700 lbs. per square inch in any test, when testing at least six ordinary samples. For the purpose of such test the gross cross sectional area shall be considered as the product of the length times the width of the block. No allowance shall be made for air spaces of block. The allowed working strength for such blocks shall not exceed 100 lbs. per gross square inch.


167


TOWN RECORDS


e. Horizontal cell blocks. The use of horizontal cell blocks shall require the entire height of the section of wall affected to be designed for a capacity not exceed- ing fifty pounds working strength per gross square inch.


f. Hollow terra cotta blocks.

The stucco shall not be considered as a part of the required thickness of the wall. When walls of hollow building blocks are veneered with brick, the facing shall be bonded to the backing with headers every eighth course of the brickwork, or with approved metal ties at the rate of one tie for each two square feet of veneered surface. Blocks shall be so laid that the shells and webs shall be superposed upon those of the adjacent blocks below.


g. Top courses of walls. Where walls of hollow building blocks laid with cells vertical are decreased in thickness, the blocks in the top course of the thicker wall shall be filled solidly with concrete, or covered with slabs of hard-burned terra-cotta or concrete at least one inch in thickness. Terra cotta, concrete, or metal slabs, or templates of approved size and thickness shall be placed under all floor beams and girders to properly distribute the loads.


(6) Ashlar. Stone, architectural terra cotta, or other approved material used for the facing of any build- ing and known as ashlar shall be not less than four inches thick and be thoroughly anchored to the backing. Ash- lar shall not be considered in determining the minimum thickness of wall as required in this By-Law unless it is at least four inches in thickness and well bonded to back- ing with alternate stones of eight inches thickness.


168
