Whenever the work load justifies or requires such  action,  the  engineering  division  may  be subdivided  into  the  following  branches: 1.  Electrical  branch 2.  Mechanical  branch 3.  Architectural  and  structural  branch 4.  Civil  branch 5.  Plans  and  specifications  branch In some PW departments, it will be desirable to  combine  the  mechanical  and  electrical  branches or to merge the civil branch into the architectural and structural branch. In all cases, surveying work is  performed  as  part  of  the  civil  component. The  PW  officer  establishes  an  engineering division  to  handle  only  routine  work.  He  relies upon  the  engineering  field  division  of  NAVFAC for the design of major public works and public utilities,  for  the  preparation  of  specifications  in connection  with  them,  and  for  the  engineering investigations in specialized fields. PW departments with limited work load and staffing  may  combine  the  engineering  and maintenance  control  components  into  a  single engineering  division. As mentioned previously, the majority of the EAs assigned to public works activities will work in  the  engineering  division.  With  the  exception of   supervision,   your   tasks,   such   as   design, reproduction,  surveying,  and  so  forth,  will  be similar  to  those  performed  in  the  engineering division of the NMCB. Often you will be the only EA assigned to a particular public works activity; therefore, your supervisory duties, if any, will be limited. MANAGEMENT ENGINEERING FACILI- TIES  DIVISION.—   This  is  the  division  in  the public  works  department  whose  entire  effort  is directed toward maintenance management. It is responsible for the integration of a maintenance work load program; the screening and classifying of  all  work  requests,  including  emergency-service- type  work,  before  submission  to  shops  for accomplishment;   the   continuous   inspection   of public  works  and  public  utilities  to  reveal  the need  for  maintenance  work;  the  preparation  of manpower and material estimates for job orders; the  determination  of  the  need  for  engineering advice  and  assistance;  and  the  initiation  of requests to the public works officer for approval to   perform   work   by   contract.   The   facilities management  engineering  division  may  be  com- posed  of  the  following  branches: 1.  Inspection  branch 2.  Planning  and  estimating  branch 3.  Work  reception  and  control  branch At  some  PWDs,  the  inspection  branch  is supplemented with experienced BUs, CEs, UTs, SWs,  and  a  few  EAs  with  broad  construction experience.  Public  works  departments  that  are primarily  staffed  with  SEABEEs  may  have  senior or  master  chief  petty  officers  for  the  inspection branch  and  planning  and  estimating  branch supervisors. Other  EA  Billets As  mentioned  earlier,  you,  as  an  EA,  maybe offered a variety of available billets or be given orders to a particular unit as the needs arise. Other types  of  billets  for  EAs  include  assignment  to Construction  Battalion  Units  (CBUs),  Naval Oceanographic   Units,    Naval   Support   Force Antarctica   (NSFA),   Underwater   Construction Teams  (UCTs),  SEABEE  teams,  and  various other   commands.   Senior   EAs   are   commonly assigned to SEABEE headquarters or regimental staff;   as   instructors   at   one   of   the   Naval Construction   Training   Centers   (NCTCs);   as personnel detailers at Naval Manpower Procure- ment Center (NMPC); and as writers of advance- ment  examinations  and  training  manuals  at the  Naval  Education  and  Training  Program Management   Support   Activity   (NETPMSA). ADMINISTRATIVE   DUTIES As  an  EA3,  you  have  a  great  deal  to  learn about your profession, including the development of skills related to drafting, surveying, materials testing, quality control, and eventually planning and  estimating.  However,  from  time  to  time, you  will  be  called  upon  to  demonstrate  your supervisory  abilities.  Your  duties  and  responsi- bilities as a supervisor will probably be limited, but they will gradually increase as you advance in  your  career  development. Becoming an EA3 is a big step in your naval career.  The  Navy  imposes  special  trust  and confidence in you. In return, the Navy expects you to  be  professionally  competent  and  capable  of instructing  and  supervising  your  subordinates. Your  example  of  leadership  and  responsibility  will 16-5
