example of one of the data displays that you can find in part 1. As you can see, figure 5-3 is for Component P-25. The   name   of   this   component   is   Naval   Mobile Construction   Battalion.   The   specific   function,   or purpose, of this component is shown directly below the component name. Listed below the function are all of the  facilities  that  comprise  Component  P-25.  For  each facility,  you  find  the  single-facility  capacity,  total quantity, and total facility capacity required for the component;  for  example,  there  is  a  total  of  two water-storage  facilities  (Facility  Number  841  40E) required for the complete component. Each of these storage facilities has a capacity of 30,000 gallons, and the total water-storage capacity for the component is 60,000 gallons. Also listed for each facility is the weight, cube,  dollar  value,  and  estimated  construction  effort  for the total quantity of each facility. At the bottom of figure 5-3, you find additional information concerning the complete component. This includes a breakdown, by Seabee rating, of the estimated direct-labor man-hours that  are  needed  to  construct  the  component. Part 2 (Facilities) includes a data display for each of the ABFC facilities. This part, indexed by facility number, is used to identify the assemblies that are required for each facility. For our discussion, let’s stay with the requirements for the P-25 Component and look at the data display for Facility Number 123 10F. This data display, found in part 2, is shown in figure 5-4. At the top of this data display (fig. 5-4) is the facility number and nomenclature of the facility. Below this, you see a listing, by assembly number, of all of the assemblies that are needed for one complete facility. This  listing  includes  the  description,  quantity,  weight, cubic feet, dollar value, and the estimated construction effort  required  for  each  assembly.  Below  the  listing  of assemblies,  you  also  find  other  information  regarding the complete facility; for example, you can see that Facility 123 10F requires a land area of 1.28 acres, that a  30-day  supply  of  gasoline  (MOGAS)  will  be  needed, and that the estimated EA direct labor required to install this facility is 8 man-hours. Part  3  (Assemblies)  is  indexed  by  assembly number  and  contains  data  displays  that  list  all  of  the materials required for each assembly. For an example, let’s look at the data display for Assembly Number 20002 that is required for Facility 123 10F. This data display, which you could find in part 3, is shown in figure  5-5.  On  this  display,  you  see  the  national  stock number  (NSN),  description,  unit  of  issue,  quantity, weight, cubic feet, and dollar value for each line item of material that is required for one complete assembly. Also,  on  this  data  display,  you  can  find  the  estimated number of man-hours and the recommended size of crew  needed  to  assemble  and  install  one  of  these assemblies. Volume I Refer again to figures 5-3,5-4, and 5-5. In each of these  figures,  you  see  reference  to  a  drawing.  It  is  for these drawings that you use volume I of the P-437. Volume  I  contains  reproducible  engineering  drawings and is organized as follows: Part 1 (Component Site Plans)  is indexed by component  designation  and  includes  typical  site  plans for the ABFC components. When a component does not have a site plan, the word None appears on the data display for the component. Part 2 (Facility Drawings and Networks)  is indexed  by  facility  number  and  contains  detailed construction  drawings  of  the  ABFC  facilities.  Also included in part 2 are construction networks. A network is  a  diagram  that  is  used  to  guide  and  manage  a construction project. It includes information, such as the sequence of construction activities, start and finish dates of each construction activity, duration of each activity, and other information that is of use to the crew leaders, supervisors, and managers of a project. The  Seabee Planner’s  and  Estimator  Handbook,  NAVFAC  P-405, provides  detailed  guidance  on  reading  and  preparing construction   networks. Part 3 (Assembly Drawings)  contains   working drawings of the ABFC assemblies. It is indexed by assembly  number. The above is only a brief overview of Advanced Base Functional Components. For more information, you should refer to the NAVFAC P-437, volume II. Q1. Q2. Q3. QUESTIONS What  type  of  guide  specifications  is  mandatory for  use  when  preparing  project  specifications  for a  nonspecialized  structure? When there is conflicting information between the drawings and the specifications, which takes precedence? Into how many divisions are project specifica- tions  divided? 5-11
