Execution for Piping Engineering

Execution for Piping Engineering


1. Introduction

Piping Engineering is one of discipline in the Engineering and Construction Company, like us we are one of the local private company in Indonesia which already exist since 1973.
Piping discipline is about 30% of the Engineering. People said that the Project will good in execution if the piping have good execution. Therefore I will share my knowledge about this piping execution.

2. Execution of Piping Engineering

Before we start, it is very important that for engineer to understand the job description. Knowing "What" to be define before take next step.
Overall Piping engineering can defied for some category :
1. Internal execution.
2. External execution.
3. Organization execution.

2.1 Internal Execution 

Internal execution normally already defined by Company Rules. Internal Work Break down structure already mention what is the battery limit among discipline.
In case Piping normally prepare such as :
1. Basic Piping Design, such Specification, Plot Plan Drawing, and Standard Drawing.
2. Piping Information, such as Piping Information to others discipline such as piping information to Civil discipline for piping loading data, Piping Information to Mech static for Nozzle Load and orientation. and etc.
3. Detail Piping Design such as prepare for Piping drawing such as Key Plan, Piping Plan drawing and Isometric Drawing.
4. Piping Calculation such as Wall Thickness calculation, stress calculations, AIV/FIV Calculation and etc.
5. Prepare Bill of Material and Bill of Quantity. BOM will deliver to SCM (Procurement) team buy the piping material and BOQ will deliver to Construction team as their basis for Subcontracting.
6. Prepare RFQ (Request for Quotation) and TBE (Technical Bid Evaluation) for piping materials.
7. Review the Vendor Documents.

2.2 External Execution

External execution mean to others discipline or to client. This kinds execution is very unique based on project. Therefore before prepare the external execution please discuss with Principle Engineer or to Piping HOD (Head of Department).
Therefore please prepare "Split of Work with others discipline" to make clear demarcation.
These kinds of sample demarcation to be cleared during project executions:
1. P&ID Mechanism, which area and what the limitation of piping scope, such as line number identifications, break class, insulation break, and P&ID Distribution diagram.
2. Un-pressurized buried pipes, some project sewer pipes is civil scope, and some project is piping scope.
3. Piping inside buildings, such as FW System inside building normally by Civil discipline
4. Piping inside package, it must be cleared for tie in point and battery limits area.
5. Piping Spool generation, current execution this pipe spool generation under construction but always open become engineering scope due to reduce the mistake.

The external execution with Client mean we  shall be working closed together with Client to have reduce miss understanding, faster closing comments, and get approval. 

2.3 Organization Execution

This execution shall be determine by Senior Engineer or Head of Department to select manpower with kinds of considerations:
1. Project scale.
2. Project schedule.
3. Project type.
4. Joint Venture or Joint Body type
5. Client type.

Those kinds consideration Department head select Lead engineer, Senior Engineer as key person to execute the project
Then Lead Engineer prepare Piping Engineering Execution plan to be presented in front of Department Head.
The preparation of Piping Engineering Execution very important to get big picture of the project.
We can know the critical path or action to be considered immediately.
One of the Organization execution is technical Audit during project executions.
Depend on the project type, how many times and what kinds of document to be audit by Piping Managements.
The usage the Company standard to be checked and compare with client standard is one of action in this execution type.


Those three type execution is very basic and general execution in Piping Engineering. Later I will continue for more detail execution.

Why we need allowance  During EPC Project, many constrain to be considered to complete the project. One of the major item is Materials. ...
