DIMENSION PAPER A. The ruling of dimension paper (see representation of an A4 page below) is vertically seperated into 2 parts by a double line. Each half is then devided in four columns (See Figure 1 below) Figure 1 B. Column A is the “timesing” and “dotting on” column where multiplication and addition of the dimensions can be recorded (See Figure 2 below) Figure 2 C. Column B is the dimension column and receives the measurements taken off from the drawings. The dimensions are normally expressed to two decimal points (See Figure 3 below) Figure 3 D. It is important to note that it is the insersion of the horizontal line which determines whether the dimension is intended as linear, superficial or cubic measurement ( see Figure 4 below) E. Practical side of Taking off Quantities: a. The dimensions should always be recorded in the order of L (Length) x W ( Width) x H ( Height) b. Column C is the squaring column where the result of the addition, subtraction or multiplications of the entries in the dimension column are recorded (see Figure 5 below) c. Numbers that are to be added together or subtracted are to be bracketed together in the manner shown. d. Deductions are some times necessary where it is easier to take an overall measurement, and then deduct the part not required (see Figure 5 below) i. L x W = 10m x 6m = 60m ; minus 3m x 2m = -6m = Total of 54m area Figure 5 F. Columns D is the description column where the item being measured is described. a. This is done by using a form of standard abbreviations which is described. b. This column also contains annotations giving the location of the dimensions and waste calculations which shows the build up of the figures entered in the dimension columns ( see Figure 6 below) c. Quite often 2 items share the same measurement andthis is indicated by linking the description with an ampersand d. It may be considered to insert the appropriate CESMM3 code in the description column as shown in Fig 6
