SUBJECT III. BUILDING CONSTRUCTION.

EXAMINERS:

COLONEL SEDDON, R.E. (Ret.),

T. BLASHILL, Esq., F.R.I.B.A.

GENERAL INSTRUCTIONS.

If the rules are not attended to, the paper will be cancelled,

You may take the Elementary Stage, or the Advanced Stage, or Honours-Part I., or (if eligible) Honours--Part II., but you must confine yourself to one of them.

All figures must be drawn on the single sheet of paper supplied, beginning on the side marked with your distinguishing number, which must face you at the right-hand top corner.

Put the number of the question before each answer, and confine your answer strictly to the question asked.

All drawings must show a correct knowledge of construction. Neat, distinct, and accurate pencil drawing to scale is required. No extra marks will be allowed for inking-in.

Where only sketches are asked for written explanations are not to be added; the proportions of the sketches must be approximately correct, though extreme accuracy, as in drawings to scale, is not necessary.

Answers in writing must be as short and clearly stated as possible, and close to any figures to which they may refer.

Your name is not given to the Examiners, and you are forbidden to write to them about your answers.

The value attached to each question is shown in brackets after the question. But a full and correct answer to an easy question will in all cases secure a larger number of marks than an incomplete or inexact answer to a more difficult one.

Questions marked (*) have accompanying diagrams.

The examination in this subject lasts for four hours.
