Equipment includes such items as medical equipment,   laboratory   equipment,   food service  equipment,  kitchen  and  bath cabinetwork,  and  counter  tops. Furnishings include  prefabricated  cabinets, blinds,  drapery,  carpeting,  furniture,  and seating. Special  Construction  includes  such  items  as prefabricated  structures,  integrated  ceiling systems,  and  swimming  pools. Conveying Systems include dumbwaiters, elevators,  moving  stairs,  material-handling systems,   and   other   similar   conveying systems. Mechanical   Systems   include   plumbing, heating,  air  conditioning,  fire-protection systems,  and  refrigeration  systems. Electrical Systems include  electrical  service and  distribution  systems,  electrical  power equipment,  electric  heating  and  cooling systems,  lighting,  and  other  electrical  items. Each of the above divisions is further divided into sections.  You  can  find  a  discussion  of  the  required sections of Division 1 in  Policy  and  Procedures  for Project   Drawing   and   Specification   Preparation, MIL-HDBK-1006/1. The   Division   1   sections, sometimes referred to as “boilerplate,” are generally common   to   all   projects   accomplished   under   a construction  contract.  Divisions  2  through  16  contain the  technical  sections  that  pertain  to  the  specific project  for  which  the  spec  writer  has  prepared  the specification. These  technical  sections  follow  the CSI-recommended   three-part   section   format.   The first part, General, includes requirements of a general nature. Part 2, Products, addresses the products or quality of materials and equipment to be included in the  work.  The  third  part,  Execution,  provides  detailed requirements  for  performance  of  the  work. GUIDANCE Usually, the engineer or spec writer prepares each section  of  a  specification  based  on  the  appropriate guide  specification  listed  in  the  Engineering   and Design  Criteria  for  Navy  Facilities,  MIL-BUL-34. This military bulletin (issued quarterly by the Naval Construction   Battalion   Center,   Port   Hueneme, California)  lists  current  NAVFACENGCOM  guide specifications, standard specifications and drawings, definitive drawings, NAVFAC design manuals, and military handbooks that are used as design criteria. As  discussed  earlier,  when  writing  the  specifi- cations  for  a  project,  you  must  modify  the  guide specification  you  are  using  to  fit  the  project.  Portions of  guide  specifications  that  concern  work  not  included in the project should be deleted. When portions of the required   work   are   not   included   in   a   guide specification, then you must prepare a suitable section to cover the work, using language and form similar to the   guide   specification.   Do   not   combine   work covered   by   various   guide   specifications   into   one section  unless  the  work  is  minor  in  nature.  Do  not reference  the  guide  specification  in  the  project specifications. You must use the guide spec only as a manuscript that can be edited and incorporated into the  project  specs. The  preceding  discussion  provides  only  a  brief overview   of   construction   specifications.   For additional   guidance   regarding   specification preparation,   you   should   refer   to   Policy   and Procedures   for   Project   Drawing Preparation, MIL-HDBK- 1006/1. and  Specification 2-21
