OTHER  SPECIFICATIONS The  following  specifications  establish  require- ments mainly in terms of performance. Referencing these  documents  in  project  specifications  assures  the procurement  of  economical  facility  components  and services while considerably reducing the number of words required to state such requirements. Federal and Military Specifications Federal  specifications  cover  the  characteristics  of materials and supplies used jointly by the Navy and other  government  agencies.  These  specifications  do not cover installation or workmanship for a particular project,  but  specify  the  technical  requirements  and tests   for   materials,   products,   or   services.   The engineering  technical  library  should  have  all  the commonly  used  federal  specifications  pertinent  to Seabee  construction. Military  specifications  are  those  specifications that  have  been  developed  by  the  Department  of Defense. Like federal specifications, they also cover the characteristics of materials. They are identified by DOD or MIL preceding the first letter and serial number. Technical  Society  and  Trade  Association Specifications Technical   society   specifications   should   be referenced in project specifications when applicable. The   organizations   publishing   these   specifications include, but are not limited to, the American National Standards  Institute  (ANSI),  the  American  Society  for Testing  and  Materials  (ASTM),  the  Underwriters Laboratories (UL), and the American Iron and Steel Institute   (AISI).   Trade   association   specifications contain  requirements  common  to  many  companies within a given industry. Manufacturer’s Specifications Manufacturer’s  specifications  contain  the  precise description for the manner and process for making, constructing, compounding, and using any items the manufacturer   produces. They  should  not  be referenced   or   copied   verbatim   in   project specifications  but  may  be  used  to  aid  in  preparing project   specifications. PROJECT  SPECIFICATIONS Construction   drawings   are   supplemented   by written  project  specifications.  Project  specifications give  detailed  information  regarding  materials  and methods  of  work  for  a  particular  construction  project. They  cover  various  factors  relating  to  the  project, such as general conditions, scope of work, quality of materials,  standards  of  workmanship,  and  protection of finished work. The  drawings,  together  with  the  project specifications, define the project in detail and show exactly  how  it  is  to  be  constructed.  Usually,  drawings for an important project are accompanied by a set of project   specifications. The  drawings  and  project specifications   are   inseparable.   Drawings   indicate what the project specifications do not cover. Project specifications  indicate  what  the  drawings  do  not portray, or they further clarify details that are not covered  amply  by  the  drawings  and  notes  on  the drawings. When   you   are   preparing   project specifications, it is important that the specifications and   drawings   be   closely   coordinated   so   that discrepancies   and   ambiguities   are   minimized. Whenever  there  is  conflicting  information  between the drawings and project specs, the specifications take precedence  over  the  drawings. ORGANIZATION  OF  SPECIFICATIONS For   consistency,   the   Construction   Standards Institute   (CSI)   has   organized   the   format   of specifications  into  16  basic  divisions. These divisions, used throughout the military and civilian construction  industry,  are  listed  in  order  as  follows: 1. 2. 3. General Requirements include  information that is of a general nature to the project, such as   inspection   requirements   and   environ- ment al protection. Site Work includes work performed on the site,  such  as  grading,  excavation,  com- paction, drainage, site utilities, and paving. Concrete includes  precast  and  cast-in-place concrete,  formwork,  and  concrete  reinforc- ing. 2-20
