IED means the Industrial Engineering Division. The main function of IED is that the customer handling. At first when a party/customer (personnel/government/non-government institute/factory) needs to make a job, it comes to BITAC and meets with IED section. Sometimes all operations of the job can not be performed in BITAC. In that case, a quotation form is given to the party and that operation is performed from any outer shop. Then IED estimates approximate cost of the job or product according to the drawing or sample and number of products.
The total cost consists of material cost, casting cost (if necessary), matching cost (depreciation cost, electricity bill, salary of the workers), overhead cost (25% of total cost and it ultimately goes to Bangladesh Bank), emergency cost (if necessary, generally 10% of the total cost), packing cost (if necessary) and transport cost (if necessary).
If the party does not select any material then IED estimates the required strength of the material according to its purpose and finally selects the material with required strength and property.
After estimating the total cost for the job, IED offers a price to the party. If the party agrees to it, then the party places a work-order to the IED. For a govt. institute/factory, the total cost can be paid after finishing the job. But for a non-govt. institute/factory, half of the total cost should be paid instantly.
Lastly IED hands over the quotation form and work-order to PCD by a job file.
PCD stands for Production Control Division. It is the heart of BITAC. PCD gets any order of a job from the party through IED. IED hands over the work order, quotation form and job’s drawing/sample provided by the party.
IED mainly operate customer handling and PCD maintains internal procedure. That means the rest procedure before handling to customer is done in the PCD section.
PCD makes an operation sheet for the job and supplies the copy of operation sheet to each floor in-charge in which the job should be replaced. PCD also supplies material
from the store. PCD selects the required time for each shop. The required time that is given for each shop to perform their duties depends upon the total time within which the job should be delivered.
Then according to the operation sheet, the job goes under different operations in the different shops. PCD operates observes whether the processes are performed in each section in time or not.
When the job becomes ready for delivery then PCD gives a letter to the party through IED informing that the job is ready for delivery. PCD also sends forwarding bill to the accounts section and the accounts section sends formal bill to the party
IS means Inspection Section. When a job is made before heat treatment the job is placed in inspection section. After inspection it transfer to the heat treatment shop. After heat treatment IS measures the jobs with measuring tools. Then they transfer to the machine shop.
