Figure  2-4.—A  truss  rafter. The engineer works with the architect to decide what  materials  to  use  in  the  structure  and  the construction  methods  to  follow.  The  engineer determines the loads that supporting members will carry and the strength qualities the members must have  to  bear  the  loads.  The  engineer  also  designs  the mechanical  systems  of  the  structure,  such  as  the lighting,  heating,  and  plumbing  systems.  The  end result  is  the  architectural  and  engineering  design sketches. These   sketches   guide   draftsmen   in preparing  the  construction  drawings. CONSTRUCTION DRAWINGS Generally,  construction  or  “working”  drawings furnish   enough   information   for   the   Builder   to complete an entire project and incorporate all three main  groups  of  drawings-architectural,  electrical, and mechanical. In drawings for simple structures, this  grouping  may  be  hard  to  discern  because  the same single drawing may contain both the electrical and mechanical layouts. In  complicated  structures, however,  a  combination  of  layouts  is  not  possible because of overcrowding. In this case, the floor plan may  be  traced  over  and  over  for  drawings  for  the electrical  and  mechanical  layouts. All or any one of the three types of drawings gives you  enough  information  to  complete  a  project.  The specific   one   to   use   depends   on   the   nature   of construction   involved.   The   construction   drawing furnishes   enough   information   for   the   particular tradesman  to  complete  a  project,  whether  architectu- ral, electrical, or mechanical. Normally, construction drawings   include   the   detail   drawings,   assembly drawings,  bill  of  materials,  and  the  specifications. A  detail  drawing  shows  a  particular  item  on  a larger scale than that of the general drawing in which the item appears. Or, it may show an item too small to appear at all on a general drawing. An  assembly  drawing  is  either  an  exterior  or sectional view of an object showing the details in the proper   relationship   to   one   another.   Assembly drawings are usually drawn to a smaller scale from the dimensions of the detail drawings. This provides a check on the accuracy of the design drawings and often  discloses  errors. Construction  drawings  consist  mostly  of  right- angle  and  perpendicular  views  prepared  by  draftsmen Figure  2-5.—The  most  commonly  used  roof  trusses. 2-5
