PowerPoint® Presentation Chapter 1 Construction Documents Construction Professionals • Working Drawings and Specifications • Prints • Drafting Methods Chapter 1 — Construction Documents Construction professionals, such as architects and contractors, utilize working drawings and specifications to coordinate their efforts in building a structure. Chapter 1 — Construction Documents 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. Chapter 1 — Construction Documents 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. Chapter 1 — Construction Documents Sections show features revealed by a cutting plane. Chapter 1 — Construction Documents Details show special features of plans as elevation or section views. Chapter 1 — Construction Documents 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 wideformat 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.
