None. Make them by itemizing everything that is required to do the job.

Is this homework? It sounds like homework. Must be homework.

Please tell me it's homework. Please tell me that you are not designing a spacecraft.

God help us all!!!!!!!!!!!!!!!!

Vishnudev,

You did not say what industry or profession you are working in.

What I am offering below relates to the Process Plant (Refinery, etc) engineering and design. Specifically the Piping material documents and activities.

This is a copy of a previous question and my answer.

MTO, BOM & BOQ

The question:

What is the meaning of MTO, BOM and BOQ and how do I start this ..... I mean some useful tips to make a BOM, MTO, BOQ...like what are the things to be considered, what all are mandatory... etc. ?"

My answer: (Based on my experience)

MTO means Material Take-Off. This is the action of counting of the pieces and parts needed to fabricate, purchase and or construct something. ("Have you started the MTO yet? - Have you completed the MTO yet?")

BOM means Bill of Material. This is normally a listing of only the material shown on an individual specific drawing such as a piping Isometric. ("Have you checked all the BOM's for the Area 10 Isometrics?)

BOQ means Bill of Quantity (also called Material Summary). This is the totaling of all the quantities from all the BOM's from all the piping drawings to send to a piping supplier for pricing or purchase.

Despite of how we describe it, there is basically no difference between MTO (Material Take Off) and BOM (Bill of Materials). They are used synonymously in the project work for material procurement. In some projects, MTO is used dominantly over BOM, while in other project it is the other way around. These are the documents which contains the list of materials of the project including the material description, vendor (supplier) name, part number, quantity etc. Generally individual MTO's (or BOM) are prepared separately for each category of materials such as Cable MTO, Piping material MTO, Bulk Material MTO etc. MTO's (or BOM) are prepared from the detail design document and they are the first document for the procurement initiative.

Pl go through this definition for :

Bill of Material (BOM)

Definitions (1)

Bill of materials (BOM) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, components, parts and the quantities of each needed to manufacture an end item (final product) .

Definitions (2)

1. List of materials required by a contractor to complete a contract, or by a supplier or vendor to complete an order.

2. List of all raw materials, parts, intermediates, sub-assemblies, etc., (with their quantities and description) required to construct, overhaul, or repair something. See also bill of quantities.

Bill of Quantities (BOQ)

Definition

Bidding document prepared usually by a quantity surveyor, it is an itemized list of materials, parts, and labor (with their costs) required to construct, maintain, or repair a specific structure.

Material Take Off(MTO)

Definition

Material Take Off (MTO) is a term used in engineering and construction, and refers to a list of materials with quantities and types (such as specific grades of steel) that are required to build a designed structure or item. This list is generated by analysis of a blueprint or other design document. The list of required materials for construction is sometimes referred to as the Material

Take Off List (MTOL).

Material take off is not limited to the amount of required material, but also the weight of the items taken off. This is an important factor when dealing with larger structures, allowing the company that does the take off to determine total weight of the item and how best to move the item (if necessary) when construction is completed.

I hope this will helpful for you!!!...
