                            Chapter 1 — Construction Documents



Construction professionals, such as architects and
contractors, utilize working drawings and specifications
to coordinate their efforts in building a structure.

Plot plans show the
shape and size of the
building lot and location
and shape of the house.
Floor plans show the
shapes, sizes, and
relationships of rooms.

Floor plans show the
shapes, sizes, and
relationships of rooms.
                            Chapter 1 — Construction Documents



Elevations show the sizes and shapes of exterior walls,
interior walls, and partitions.

Sections show features revealed by a cutting plane.
                       Chapter 1 — Construction Documents



Details show special
features of plans as
elevation or section
views.

Title blocks include the
sheet number, architect
or design firm name,
owner, and other
pertinent information.
                            Chapter 1 — Construction Documents



Specifications include information such as the materials
used in the construction and the responsibilities of
those involved.
                            Chapter 1 — Construction Documents



Original drawings are
produced using either
conventional drafting or
CAD. Working drawings
are printed using a wide-
format printer.
                             Chapter 1 — Construction Documents



LED printers use light-emitting diodes to project light
onto a photoreceptive drum enabling fast production
of detailed working drawings.
                           Chapter 1 — Construction Documents



Conventional drafting tools include T squares,
triangles, scales, and pencils. Drafting instruments,
such as dividers, may also be used to create drawings.
                           Chapter 1 — Construction Documents



The 30°-60° and 45° triangles are used to draw lines
15° apart.
                         Chapter 1 — Construction Documents



A compass is used to
draw arcs and circles.
Dividers are used to
transfer measurements.
                              Chapter 1 — Construction Documents



Three types of scales are
used to produce scaled
drawings. The architect’s
scale is typically used for
building trades plans.
                           Chapter 1 — Construction Documents



Pencil leads range from extremely soft to
exceptionally hard.
                        Chapter 1 — Construction Documents



CAD-generated plans
have consistent line
weights, symbols, and
lettering.
                           Chapter 1 — Construction Documents



A CAD system includes a keyboard, central
processing unit (CPU), monitor, and input devices.
                          Chapter 1 — Construction Documents



Wide-format LED
printers are used to
print working drawings.
The printers may have
an integrated scanner,
stacker, or folder.
                            Chapter 1 — Construction Documents



Building information
modeling (BIM) is used
to recognize and resolve
any inconsistencies or
conflicts between
various sets of drawings
prior to the beginning of
construction.
