Survey of a Building: 31 // 31 Sketch (out-of-door work,) 8 / 8 Drawing, 21 / 21 Memoir, 2 / 2 Representation of an existing building or a part of a building by means of plans, sections, and elevations. The memoir contains an accurate and critical description of the distribution, construction, and decoration of the building. Each day is equivalent to 4½ hours’ work. The sketches are executed to scales approximating to one-fiftieth for the whole drawing, of one-twentieth for the large details, and of ¼ to ½ for the minute details. The drawing prepared from the sketches is made on the scale of 1-100th. Project for a Building: 42 // 42 Sketch, (first study in pencil.) 12 / 12 Drawing, (fair copy) 18 / 18 Details, 4 / 4 Memoir, 4 / 4 Abstraction of Measurements and Estimates 4 / 4 Study and preparation of a project of a building, in accordance with certain given data. The sketches, the result of the first study, are made in pencil; the drawing is the fair copy of the sketch, modified as may be necessary. The memoir contains an explanation of the rules and principles which must be observed in the construction of buildings, and the grounds on which the dispositions contained in the building have been adopted. The abstraction of the measurements and their reduction to the proper elements, and the estimates, are prepared in conformity to the instructions laid down for the Engineer Service in towns: these supply the estimated cost of the construction of the building according to the project. This work, common to the students of the two arms, is an application of the first part of the course. The scale for the drawing is in general 1-200th for the plans and elevations, and 1-100th for the sections. It is restricted by the condition that the whole of the drawings should be given on a single sheet of paper. The details need only occupy half a sheet of paper, and its scales must depend on the size of the objects to be represented. The details need only occupy half a sheet of paper, and its scales must depend on the size of the objects to be represented. The project for a building is an application of the first two parts of the course, as well as of the 1st section of the 3d part.
