Architectural/Structural Steel Drawings, Continued
Blueprints used in the fabrication and erection of steel structures consist of a
group of different types of drawings, such as layout, general, fabrication,
erection, and falsework.
LAYOUT DRAWINGS: Layout drawings, often called general plans or
profile drawings, provide information on the location, alignment, and
elevation of a structure and its principal parts in relation to the ground site.
They may also provide information on the nature of underlaying soil or the
location of adjacent structures or roads. Written specifications usually
supplement layout drawings.
GENERAL PLANS: General plans contain information on the size,
material, and makeup of all main members of the structure, their relative
position and method of connection, as well as the attachment of other parts of
the structure. They consist of plan views, elevations, and sections of the
structure and its various parts.
FABRICATION DRAWINGS: Fabrication or shop drawings contain all the
necessary information on the size, shape, material, and provisions for
connection and attachments for each member.
There is sufficient detail to
order material and begin construction.
ERECTION DRAWINGS: Erection drawings or erection diagrams show the
location and position of various members in the finished structure. They are
particularly helpful in the field when they show the approximate weight of
heavy pieces and the number of pieces.
FALSEWORK DRAWINGS: Falsework drawings are drawing that show
temporary supportive construction necessary to the erection or construction
of difficult or complicated structures.
