Can any body explain me what is BOM, TOM and BOQ and how it can be prepared?

MTO means Material Take-Off.

BOM means Bill of Material.

BOQ means Bill of Quantity.

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 Area10 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 project to send to a piping supplier for pricing or purchase.

In an EPC awarded contract such terms are defined from calculating MTO's from P & I D / General Arrangement  and Isometrics Drawings. These are intended for procuring materials in accordance to the approved for Construction Drawings, The DELIVERY schedule is based on  TOM ( TARGETED MILESTONES FOR COMPLETION OF THE PROJECT)

efinition used by the ISA (International Society of Automation): A Material Take Off (MTO) is the process of analyzing the drawings and determining all the materials required to accomplish the design. We then use the material takeoff to create a bill of materials (BOM). Inspection does not aid in creating a bill of materials. Procurement and requisition are activities that occur after the bill of materials is complete.

BOM means bill of material and others having same meanings.the BOM is the list and the specification of the materials which is used for the construction of specific spool and it is clear described in the isometric drawing 

BOQ -Bill of Quality

MTO-Material Take off

Bill of materials , Bill of quantity 

if you can do them then you can but them as skills in your CV

for example:Quantity surveying by using excel program and preparation of BOQ, BOM, TOR, VO.
