Material coding schema
- 1. Material coding hydro power project The designed schema is to assign 12 digit code to all materials The Schema hierarchy is as follows:
- 2. Main First two digits ‘00’ to 99 having 42 main groups and 58 Groups blanks for future use Sub Third & fourth digit constituting four digit Groups ‘0000’ sub-group codes for each main group totaling 369 sub groups to cover all the items used in a hydro power plant the number of SG may further increase depending up on the type and expanse of items Sub- Fifth & sixth digit constituting six Sub digit ‘000000’ of sub-sub-group groups codes for each sub group totaling 2293 sub-sub groups to cover all the items used in a hydro power plant the number of SSG may further increase depending up on the type and expanse of items.
- 3. Category Seventh & eighth digit constituting eight digit ‘00000000’ of category codes for each sub-sub group totaling 6902 categories to cover all the items used in a hydro power plant the number of CTGRY will further increase depending up on the type and expanse of items particularly in MG 36, 37, 46, 67, 74, etc where technical classification remain common for each sub-sub group of items say gate valve cast steel may have many NBs in its category. Parameters Ultimate 9th to 12th digits making twelve digit ‘000000000000’ item code under each category. In several cases even last four digits follow technical parameters of the items and will not be a serial number.
