Engineering Phase


Multidisciplinary activity through which technicalspecification of plant components and relative ways of

installations are defined, on the basis of prefixed

10

(material take-off ) and to define ways of construction/assembly (sketches)



Engineering Phase


Front End Engineering

Engineering for Requisitioning and Procurement

11

Engineering for Construction/Assembly

Engineering during Construction



Engineering Phase


Front End Engineering task is to define design choicefundamental for each specialist discipline, coherently

with base engineering, to start supply campaign

’

12



Engineering Phase


Engineering for Requisitioning and Procurementdevelops through the following:

• formulation of technical specifications for Request for

13

• formulation of technical opinions on offers coming

from suppliers;

• control and approval of technical documentation

coming from selected supplier



Engineering Phase

Technical documents

• to specify technical characteristics of a

plant/component• to specify ways of construction, assembly, testing,

exercise, maintenance

14

•

absolving, authorizations, etc.



Engineering Phase

Technical documents Life-Cycle

1. planning2. elaboration

3. filing

15

4. transmission (if the document is used during theproject in progress)

5. research and rendering (if the document is used in

other projects)

Procurement Phase

Site Logistics

Product Support Logistics

a er a s og s cs

17



Procurement Phase

Materials logistics can be divided in:

Materials Management to guarantee the

presence of materials on site

18



Procurement Phase

Procurement

Supplied materials:

• construction materials;

• p an componen s;

• consumption materials;

• operating means and advices.

19



Procurement Phase

Procurement

Vendor List

Procurement Phase

Procurement Phases1. Emission of “Purchase Specification” (from Engineering and

Procurement);2. Emission of “Inquiry for Bid” (from Procurement and supplier

inserted in vendor list);

Engineering);4. Economic tabulation of received proposals (from

Procurement);

5. Emission of “Inquiry for Purchase” (from Engineering);

6. Order emission (from Procurement);7. Final approval of supplier technical documentation (from

Engineering).

Procurement Phase

Materials Management

Expediting

Inspecting and testing

TransportsReception/storing/handling of materials in

site

22



Procurement Phase

Expediting

This phase guarantees the control of

milestones corresponding to the right

progress of the project

Aims to obtain from the supplier information

about:

• furniture progress• technical documentation development

• completion of foreseen testing

23



Procurement Phase

Expediting Activities• reunions among order manager, supplier and

corporate functions interested• detailed exam of the order, identifying uncertainty

areas that could determine delivery delay

• control milestones definition and interventionsfrequency between them

• actions of reminder (visits, phone calls, meetings)

•

expediting report, sent to corporate functions

24



Procurement Phase

Expediting ActivitiesMaterials Statur Report

• material description

• number of purchase specification

•

• supplier

• number of order

• planned, foreseen and actual date of completion

• planned, foreseen and actual date of testing

• way of testing

25



Procurement Phase

Expediting ActivitiesMaterials Statur Report

• planned, foreseen and actual date of free factoryrendering

• wa of shi ment and carrier

• planned, foreseen and actual date of shipment• planned, foreseen and actual date of delivery to the

site

• corresponding activity of construction/assembly

• planned and foreseen date of activities execution

• date for which materials availability on site is

required26



Procurement Phase

Transports

Transport Plan

• ways of transport

• paths

•

contract typology (for example “door todoor”)

• carrier

• charges• packaging

• delivery dates

27



Procurement Phase

Transports

Delivery documents are very important from a

contractual point of view because theyactivate payment share from the customer

28



Procurement Phase

Inspecting and Testing Activities

• participation to technical qualification of

suppliers

• verification of suppliers’ quality warranty

• technical supervision through inspections

aimed to verify conformance of materials,

processes, construction methodologies, and

order specifications.

29



Procurement Phase


The level of supervision depends on

supplied components characteristics and

on quality level of the plant that have to

be realized

30



Procurement Phase


1) PRODUCT CATEGORIES

1 – realized on demand on supplier’s engineering

2 – realized on demand on E&C society’s engineering

–

2) QUALITY CATEGORIES OF PLANTS/SYSTEMS

1 – particularly high2 – high

3 – normal

31



Procurement Phase


Supervision Levels:

– inspection during furniture and presence

during testing (intermediate and final) at

’

– only presence during testing (intermediate and

final) at suppliers’

– acceptance of materials on the basis of documents (without presence during testing)

32



Construction/Assembly Phase

Collocated at the end of detailed

engineering (that provides technical

documents) and procurement (thatguarantees availability of materials to

ns a , an prece es s ar -up an

testing phases, where technical

performance of the plant are verified

33




Aspects to consider : changes in scope of work

materials amount revision

site logistics and transport and communication

infrastructure

activities programming and temporal profile of resources’ utilization

availability of technical documents and materials on

site contractual constraints

plan of security on site

problems from operating in strangers countries

34




Specialist work processes constructive

sequence

Constructive area/draft/cubeCrossing assembly processes and constructive

phase is obtained

Subcontracts

35




Constructive area approach

Materials may be installed:

• per area and per system (e.g. piping)

• per area (e.g. conduits)

• per system (e.g. cables)
