Contracting Series, GS-1102 TS-71 December 1983
short contractual periods (usually within 30 days); (g) large volume of actions; and (h) adequate
sources of supply, usually within the local area.
Some requirements and considerations of acquisition in the GS-1105 series are similar to, or the
same as, those in the GS-1102 series, such as use of special socioeconomic provisions, lack of
suppliers, negotiation of prices with sole source suppliers, and justification of price increases.
Thus, it is not the product or service nor the presence of special requirements which
distinguishes the GS-1105 from the GS-1102 series, but rather the procurement through
simplified purchase procedures instead of through formal advertising and negotiation
procedures.
Some organizations combine purchasing by simplified purchase procedures with contracting. As
a general principle, the appropriate series, i.e., GS-1102 or GS-1105, for such a position is the
one that fits best in terms of sources of recruitment, lines of promotion, reasons for the position's
existence, and knowledge required.
7. Positions responsible for the performance or supervision of clerical work in support of the
purchase or contracting or supplies, services, or construction are classifiable to the
Procurement
Clerical and Assistance Series, GS-1106, when the work requires a practical knowledge of
procurement procedures, operations, and regulations of the agency.
Typical assignments include preparing, controlling, verifying, or abstracting procurement
documents, reports, or industry publications; assembling contracts; performing limited contract
administration; or performing other work of a similar nature. When the position is performing
limited contract administration duties which are properly classifiable to the GS-1102 series in
combination with work classifiable to the GS-1106 series, the general principle (above) applies,
i.e., the appropriate series (GS-1102 or GS-1106) for such a position is the one that fits best in
terms of sources of recruitment, lines of promotion, reasons for the position's existence, and
background knowledge.
8. Positions that apply a knowledge of the business practices, rate structures, and operating

Public Utilities Specialist Series, GS-1130.
9. Positions concerned with purchasing agricultural commodities as a means of providing price
support to producers are classifiable to the

10. Positions which require a practical knowledge of the nature and operations of an industry or
industries, and the materials, facilities, and methods employed by the industry or industries in
producing commodities, are classifiable to the
