Figure 4-1.—Hot- and cold-water riser diagram. Show the location and direction of all new utilities, of all materials, such as concrete and reinforcing steel. unless separate utility site plans are included in other divisions,   such   as   the   mechanical,   plumbing,   or electrical  divisions.  That  is  sometimes  done  for  large, complex  projects. ARCHITECTURAL  DIVIS1ON The architectural division includes drawings, such as  floor  and  roof  plans,  interior  and  exterior  elevations, millwork,  door  and  window  schedules,  finish  schedules, special  architectural  treatments,  and  nonstructural sections and details. For a discussion of these drawings, you  should  review  chapter  10  of  the  EA3  TRAMAN. STRUCTURAL  DIVISION The structural division is comprised of all of the drawings that fully describe the structural composition and integrity of a building or structure. Included in the division  are  the  foundation  plan  and  details;  floor,  wall, and roof framing plans and details; reinforcing plans and details;  beam  and  column  details;  and  other  such structural plans and details. In a set of drawings, the first sheet in the structural division also should include, when applicable,  roof,  floor,  wind,  seismic,  and  other  loads, allowable soil bearing capacity, and allowable stresses Again,  you  should  review  chapter  10  of  the  EA3 TRAMAN. MECHANICAL  DIVISION The mechanical division includes the plans, details, and schedules that describe the heating, ventilating, and air-conditioning   (HVAC)   systems   equipment   and installation requirements. We’ll discuss more about these systems later in this chapter. The mechanical division also includes plumbing drawings that show the fixtures, water supply and waste disposal  piping,  and  related  equipment  that  are  to  be installed in a building. The drawings include plumbing plans, riser diagrams, details, and fixture schedules. Remember, that in the order of drawings, plumbing drawings always follow the HVAC drawings. As you recall from your study of chapters 8 and 10 of the EA3 TRAMAN, a plumbing plan (or layout) is a plan  view  of  the  fixtures,  lines,  and  fittings  to  be installed in a building. For an uncomplicated building containing,  let’s  say,  one  water  closet  and  one  lavatory, you can easily prepare a plumbing plan that can be clearly interpreted by the planners and estimators, inspectors, or other users of the drawing. For such a building, the plumbing plan might well be all that is 4-2
