The value of these sketches for future reference, and as aids to officers in their professional constructions hereafter, will be very much enhanced by having the dimensions clearly written on them, which should include at least those of all principal parts of machines and structures.
This part of the course occupies about three weeks, inclusive of the time required to visit the works referred to.
The officers will also be instructed, after they leave the course of construction, in the method of testing the quality of some of the materials by chemical analysis, for which a fortnight is allowed.
Part III.—Valuation and Measurement of Work.
This part of the course will occupy in all about 37 days, and will commence with a series of lectures, the subject matter of which will be found chiefly in the printed “Notes on the Practice of Building” and “Notes on the Building Trades.” They will comprise, in separate lectures for each trade,—
1. The materials, tools, etc., and apparatus employed, together with their application to the different kinds of work produced.
2. The technical terms in vogue.
3. The general practice of measuring and valuing.
Hints and memoranda useful in designing, estimating, and carrying out works will be given, and explanations afforded by reference to models and drawings, from some of which colored sketches, with the names and dimensions of the different parts given on them in full, will be made by each officer and attached to his printed notes. These sketches will be done in the Hall of Study from the originals deposited there.
A lecture will be given explaining the different steps taken in preparing the annual estimates of a district, to be laid before Parliament, and the various methods of carrying out the services which may be authorized.
