MTO GUIDELINES & PHILOSOPHY

Purpose of this philosophy is to establish guidelines for the material takeoffs

accurately for the project.

MTO GUIDELINES & PHILOSOPHY

WHY GUIDELINESREQUIRED ?

As we know in any project many people work together. People may be following different philosophies with different mindset as per their previous organization. � This guideline is required to bring complete task force of the project on the same platform with common conce

pt. � These guidelines are required to save man-hours and

bring quality to the MTO.

MTO GUIDELINES & PHILOSOPHY

MTO Preparation Methodology

� It is the responsibility of project LE and Material LE to prepare a proper guideline and methodology with reference to the ITB considering specific client requirements .

� This guideline shall be properly shared and understood among all the task force members.

� It is the task force members responsibility to adhere to the requirement of guidelines and maintain the accuracy.

MTO GUIDELINES & PHILOSOPHY

MTO Preparation Methodology

� The methodology of preparation of MTO is different for different type of projects. Therefore the guidelines and method of preparation of MTO shall be defined based on the project requirements.

Project means –Detail engineering projects, FEED as well

as proposals.

MTO GUIDELINES & PHILOSOPHY

Philosophy & Guidelines for Proposal work

�Proposal work is a fast track activity having short time duration, hence the approach towards this work should be different. No 3D modeling activity is performed in proposal. The Philosophy of MTO for proposal is as follows:

� 1. Prepare preliminary study to establish the routing ofmain process lines

�2. Prepare sketches for all P&ID lines irrespective of sizes.

� 3. Prepare sketches for all Equipment trims� 4. Prepare piping MTO for the below on the basis of

standard sketches:• Safety shower & Eye wash piping• Utility station• Vent & Drain assemblies• Steam Trap assembly• Pump & Compressor auxiliaries • LG/LT Drain & Vent assemblies • Sample Connections

MTO GUIDELINES & PHILOSOPHY

Philosophy & Guidelines for Proposal work

�5. To maintain the quality, MTO sketches for highersizes, rating and material should be checked before key-in.

� 6. It is recommended to prepare a separate valve MTO directly from the P&IDs and establish a comparison with key-in MTO to maintain high accuracy level.

Preparation of MTO for FEED Job

� FEED job requires more detailed study than proposals. The schedule duration of FEED job is normally more than proposal job. Generally 3D modeling is performed for 3” and above lines and MTO sketches are made for below 3” lines.

� PDS dump is used for the preparation of MTO for 3” above lines and manual key-in is used for below 3” lines.

MTO GUIDELINES & PHILOSOPHY

DETAIL ENGINEERING JOB

In detail engineering job MTO takeoffs will be done mainly in three steps i.e.

� Preliminary Takeoff or First MTO� Secondary Takeoff or Second MTO� Final Takeoff or Third MTO

MTO GUIDELINES & PHILOSOPHY

PRELIMINARY TAKEOFF

The purpose of the Preliminary takeoff is as follows:

� To identify material requirements for which quotes can be obtained

� To place PO for items requiring lengthy lead times such as manufacturing or extended shipping schedules

� To place orders for bulk quantities of carbon steel and alloy materials.

MTO GUIDELINES & PHILOSOPHY

PRELIMINARY TAKEOFF

The First MTO is made in the early stages of the job. The preparation of First MTO normally use the following documents:

I. Plot planII. P&IDsIII. Piping sketchesIV. Piping transpositionsV. Piping drawings

This MTO should identify approximately 65-75% of the final requirements for carbon steel material and 85% of the alloy materials.

MTO GUIDELINES & PHILOSOPHY

SECONDARY TAKEOFFThe purpose of Secondary Takeoff or Second MTO is to further identify the piping material requirements. From these requirements, additional bulk materials are consolidated and purchased.

The secondary material takeoff is normally performed after Client review and approval of Piping and Equipment design model.PDS dump will be used for development of Secondary Takeoff. The secondary takeoff should identify more than 90% of material requirements including piping specialties items.

MTO GUIDELINES & PHILOSOPHY

FINAL TAKEOFF

The purpose of Final Takeoff or Third MTO is to completelyidentify the piping material requirements. This bill of material shall be used for material requisition at site.

The Third MTO should include 100% of all known material..
