CHAPTER 4 PROJECT  DRAWINGS As you learned in chapter 10 of the EA3 TRAMAN, a  construction  drawing  maybe  one  of  several  different types  depending  upon  its  intended  use;  and,  in  practice, more than one type may be used during the design and construction of a new facility or structure. For instance, a presentation drawing (often based on a NAVFAC definitive design)  maybe prepared to “sell” an idea or concept for anew facility. Them, after the design phase is completed, the facility is constructed using one or more sets of shop drawings  and, of course, a set of project (or working) drawings. Shop drawings, as you recall,  are  those  drawings,  diagrams,  or  other-related data that are used to illustrate a material, product, or system;  for  example,  a  shop  drawing  might  be  an assembly  drawing,  prepared  by  a  manufacturer,  to describe  the  proper  steps  in  assembling  a  set  of commercially purchased cabinets. Project drawings are those drawings that describe to construction crews the construction  of  a  complete  facility  or  structure.  These drawings  are  most  often  supplemented  with  shop drawings   and   project   specifications   (discussed   in chapter  5  of  this  TRAMAN). Our discussions in this chapter center on project drawings   as   they   pertain   mostly   to   building construction. In the EA3 TRAMAN, you learned that NAVFAC   project   drawings   are   divided   into   the following categories or divisions: civil, architectural, structural,  mechanical,  electrical,  and  fire  protection. Our  discussions  will  include  a  brief  review  of  the information  you  learned  in  the  EA3  TRAMAN concerning these divisions. We also will expand on the EA3 TRAMAN information by including a discussion of heating, ventilating, and air-conditioning systems and drawings;  riser  diagrams  for  plumbing;  and  electrical wiring  diagrams  and  schedules.  In  addition,  you  will  be provided with information and tips that you can use when checking and editing project drawings. For  NAVFAC  policy  regarding  project  drawing sizes, formats, and conventions, you should refer to Policy  and  Procedures  for  Project  Drawing  and Specification Preparation, MIL-HDBK-1006/1 and to the  various  Department  of  Defense  (DOD)  standards, military standards, and American National Standards Institute   (ANSI)   standards   referred   to   in MIL-HDBK-1006/1. PROJECT DRAWING DIVISIONS The  following  paragraphs  briefly  describe  the contents  of  the  drawing  categories  or  divisions mentioned  above. CIVIL DIVISION The drawings contained in the civil division are those  that  describe  the  existing  conditions  and  planned development  of  a  project  site.  As  applicable  to  any particular   project,   the   division   typically   includes drawings that describe, at a minimum, the following information: 1. maps) 2. 3. Project  location  (shown  on  regional  and  vicinity Soil boring logs and profiles. Existing  site  conditions  to  include  terrain contours, buildings or structures, utilities, drainage, and other physical features on or near the project site. For small projects, this information can be shown in the site (plot)  plan;  however,  for  large  or  complex  construction projects,  it  is  often  shown  in  a  separate  existing conditions  plan. 4.  Planned  demolition  of  existing  buildings, structures, utilities, or other physical features that must be demolished as a part of the project. Dependent upon the complexity of the project, you may show this in the site plan or in a separate demolition plan. 5. Planned grading for surface drainage (shown by contours   or   a   combination   of   contours   and   spot elevations)  and  the  planned  grading  and  paving  of driveways, access roads, and parking areas. For grading and  paving,  you  should  show  plans,  profiles,  cross sections, and paving details as necessary to describe the new construction fully. Also show details for any curbs, gutters,  sidewalks,  and  so  forth.  Again,  dependent  upon the complexity of the project, you may show all of this in the site plan or in a separate grading and paving plan. 6.   Proposed   site   plan   showing   property boundaries, construction limits, and exactly defined locations and finished floor elevations of new buildings or structures. Each building or structure should be located  using  a  minimum  of  two  location  dimensions. 4-1
