The PAO(Ors)EME traces it origin to pre-independent era, then known as Field Pay Office, functioning at Jabalpur for both EME and AOC Corps. In the year 1943, a separate PAO for EME Corps was formed. Since then, marching along with the changing needs/strategies of defence services, in June 1948, it was moved to the "Garden City" of Bangalore. During the year 1951 it was renamed as PAO(ORs)EME. On 5th May, 1958, it was shifted to Secunderabad and starting function with effect from 23rd May 1958.The office functioned for about four decades under high roof barracks which were built for British Officers Hospitals in 1870.
The PAO got its own building in 1999 built in an area of about 3.5 acres with a plinth area of 6500 Sq. Mtrs.
PAO(ORs)EME, in its initial stages was headed by Officers, designated as DFCMA(Deputy Financial Controller of Military Accounts). Prior to 1962, the total strength of IRLAs was about 35,000 and the staff strength was around 600. After 1962, the strength of the PBORs has risen to around 1,30,000.
PAO(ORs)EME is primarily responsible for holding and maintaining the pay and provident fund accounts of approximately 1.10 lakhs EME personnel below officers rank(PBORs).
In addition to the maintenance of the IRLAs of the effective PBORs, PAO also maintains the closed IRLAs of non-effective personnel and ensures payment of any dues which may come to light as due to them subsequent to their final settlement.
Computerization of accounts of PBORs started in the year 1991. Presently this office has a full fledged EDP Centre with modern systems hardware. The system relies on the software developed "in-house" by the department in COBOL on UNIX based environment. This is now switched over to more current RDBMS based on-line System called "Dolphin".
The PAO in its advisory capacity not only aids the Executives at EME Records and EME Depot in coping up with their day-to-day functions but also imparts training to their general duty staff on matters relating to the correct publication of DOs II etc at not only local units but also various out-station units spread over the length and breath of the country.
