Construction Mathematics
• Hopefully we will develop some shortcut strategies that you can employ in the field.
BCT 104Construction Mathematics
MEPOur goal is to learn some math, and some math tricks, that you
can utilize in the field
Tape Measures
• Site Measurements and Surveyors will use longer tapes. 150’ and 200’ lengths are common
Calculators
• Any Scientific Calculator with keys for Pi, Square Root, Squared, Cosine, Sine, Tangent etc, will do
Scales
• Architects and Engineers use scale rulers, which allow them to represent actual size in a reduced form, while maintaining proportional relationships
Scales
• Most scales indicate a variety of different ‘Scales’ to choose from. House plans are typically drawn at ¼” = 1’
Scales
• By using scale, the drawing will fit on a page, and all relationships between pieces are accurately represented.
• The length of these rafters, however, must still be calculated
Scales
• The drawing does not represent the three dimensional nature of the rafters, which is assembled in our brains by viewing the plan, and the elevation, and putting two and two together
Scales
• Scale Models provide a quick and easy way to ‘test’ what a particular building configuration will look like
Scale
• Architects use scale models to help Owners visualize what a particular design will look like, which is particularly helpful for Owners unfamiliar with reading drawings.
• This can also help a contractor understand a particularly challenging roof assembly or other unusual conditions.
Scale
• Real estate plans are often ‘Not to Scale’, forcing a potential tenant to rely upon the measurements provided on the drawing. The plans can rarely be ‘scaled from’.
• We will learn how to calculate square footages, Area, and also cubic feet, or Volume.
