In addition to the subjects enumerated for the Elementary Course - in all of which questions of a more complicated nature may be set, combining work done by the different trades - the knowledge of the students will be tested under the following heads, viz.: -
1 st. Freehand sketches explanatory of any details of construction, such as the joints of iron and wooden structures, and other parts requiring illustration on an enlarged scale. These sketches may be roughly drawn, provided they are clear and capable of being readily understood.
2nd. The nature of the stresses to which the different parts of simple structures are subjected, as follows : -
In the case of beams either fixed at one or both ends, or supported or continuous, the student should know which parts of the beam are in compression, and which in tension.
He should be acquainted with the best forms for struts, ties, and beams, such as floor joists, exposed to transverse stress.
He should know the difference in the strength of a girder carrying a given load at its centre, or uniformly distributed.
He should be able, in the case of a concentrated or uniform load or a part of a beam supported at both ends, to ascertain the proportion of the load transmitted to each point of support.
3rd. The nature, application, and characteristic peculiarities of the following materials in ordinary use for building purposes, viz.: -
Bricks of different kinds in common use, York, Portland, Caen, and Bath stones (or stones of a similar description), granite, pure lime, hydraulic lime, Portland and Roman cement, mortars, concretes, grout, asphalte, timber of different kinds in common use, cast and wrought iron, lead.
4th. Constructive details, as follows : -
The ordinary methods of timbering excavations, such as for foundations to walls, or for laying down sewers; the erection of bricklayer's and mason's scaffolding; the construction of travellers; the use of piles in foundations, hoop-iron bond in brickwork, diagonal and herring-bone courses in ditto, damp-proof courses, bond timber in walls, and the objections to it.
He should know how bricks are laid in hollow walls, window or door openings with splayed jambs, flues, chimneys, fireplaces, and arches up to about 20-feet span; how mortar joints are finished off, and the thickness usually allowed to them; why bricks and stones ought to be wetted before being laid.
He should be acquainted with the construction of brick ashlar walls, rubber ashlar walls, stone stairs, wooden stairs (both dog-legged and open newel), skylights, fire-proof floors (such as brick arches supported on rolled or cast-iron girders, Fox and Barrett's, and Dennett's patent concrete floors), circular and egg-shaped drains, roofs of iron or wood, for spans up to 60 feet; the fixing of architraves, linings, and skirtings to walls, shutters to windows, lath, plaster, and battening to walls, roof coverings of tiles and zinc, slate ridges and hips.
Written answers will be required to some of the questions.
The candidate will have to furnish a design for a building, or part of a building, in accordance with given conditions, which design he will be allowed to draw out at his own home.
He will be called upon to answer in writing - illustrated by sketches either freehand or to scale, as directed - questions on all the subjects previously enumerated for the elementary and advanced Courses.
He must possess a more complete knowledge of building materials, their application, strength, and how to judge of their quality; and in the case of iron, of the processes of manufacture, and the points to be attended to in order to insure sound castings, and good riveting.
He must be able to solve simple problems in the theory of construction, and to determine the safe dimensions of iron or wooden beams subjected to dead loads.
In ordinary roof trusses and framed structures of a similar description, he must be able to trace the stresses, brought into action by the loads, from the points of application to the points of support, as well as to determine the nature and amount of the stresses on the different members of the truss, and, consequently, the quantity of material required in each part.
In ordinary walls and retaining walls he must be able to ascertain the conditions necessary to stability,neglecting the strength of the mortar.
