Introduction

FEED Engineering Design Integrity Workfl ow (EDIW)

EDIW is AMEC’s best practice guidance to Engineering Managers and supporting

personnel for the delivery of technical integrity. It is an ‘aide-memoir’ that highlights

the key deliverables and activities throughout the lifecycle of a typical FEED project.

FEED is broken into six phases:

1

Scope

Defi nition and Engineering Execution Strategy

2

Commencement of FEED Design

3

Initial FEED Development and Hazard Identifi cation

4

Initial Design Review & Audit

5

FEED Design Approval (AFD)

6

Final Reviews and Feed Report Compilation

The workfl ow shown in the EDIW Road Map illustrates the execution sequence on a generic

FEED Project. The vertical columns show activities that can be undertaken concurrently whilst the

sequential fl ow of work is across the Road Map. As the deliverables and activities in each phase are

completed, work can transition into the next phase.

Situations will arise when work will need to be be done out of sequence, typically to meet a

demanding project schedule. Use of the EDIW allows the risks of out-of-sequence working to be

identifi ed and the necessary mitigation strategies to be put in place.

AMEC’s corporate governance and assurance of Engineering will measure compliance with the

EDIW workfl ow and ensure out-of-phase working is being identifi ed and managed. This document

contains a copy of the FEED EDIW Road Map and includes detailed descriptions of the
