1. Introduced data management concept.

2. Streamlines data flow.

3. Enforced data preparedness.

4. Removed chaos from data exchange.

5. Enforced data standardization.

6. Breaks old habits (at the price).

Aveva impact on the business

In today’s project environment two ingredients are vital to its

success – keeping with the budget and keeping with schedule. With

the fierce competition on the labor market, company that can

provide both is a sure winner. Among number of other skills, proper

organization and handling of the large amount of data flooding

everyone involved is a paramount. One of the tools provided to deal

with this challenge is data storage software known otherwise as

database.

However, if it is not used properly it will only add to the chaos.

1. Project design stages are all about data and information.

IntroductionNeed of data

2. Controls, Instrumentation, Electrical in design stages are offering nothing more than data

in different formats.

3. Drawings, Excel files, PDF articles, Word documents, JPG Pictures. How do we manage following:

a) Data change?

b) Data addition/deletion?

c) Data check?

4. Who is responsible for data maintenance or data flow?

b) Incorrect I/O assessment

c) Data transfer confusion

Page 11

Sources of Ambiguity

1. Unclear responsibilities.

2. Different Professional Backgrounds.

3. Multiple Information Source.

4. Cultural Barriers And Differences.

5. Employee Experience Level.

1. Project Group

a) Ineffective project team.

b) Bad decisions based on bad data.

c) Appearance of incompetency to the client.

d) Damaged corporate image.

e) Loss of future contracts.

The Consequences

Page 13

1. Cost of fixing errors

2. Cost of the unnecessary extra equipment

3. Engineering time

4. Cost associated with changes on site

Impact on the Budget

Page 14

1. Extended development time.

2. Missed milestones.

3. Extended commissioning time.

Impact on the Schedule

Page 15

1. Educate and create buy in by project team and management.

2. Get right people for the job (it may bring higher costs at the beginning, but huge savings at

the end).

3. Spend time in preparing data at the beginning of the project.

4. Implement strict rules while handling data.

5. Create specific roles with clearly defined expectations.

Solutions?

Page 16

1. Instrumentation Lead

Instrumentation technician or engineer shall be responsible for all details pertaining to the

instrument and instrument installation only. Specification of all of the instrument requirements is

solely in this person scope of work and he/she will be responsible before the project.

Solutions?

Assign specific duties to the roles

Page 17

1. Controls Lead

Controls Lead or designate is responsible for I/O assignment. However, this is an activity that

belongs to the latter part in the project. Involvement is not expected early, but it is vital and the I/O

review shall be conducted as soon as possible.

They are also responsible for creating reports pertaining to Control Systems – Instruments

Ranges List, Alarms List, S(et)P(oints) List.

Using Electrical Module loop drawings should be created by Controls Group

Solutions?

Assign specific duties to the roles

Database Manager/Lead:

1. Creating Initial Entries

2. Managing changes

3. Adding and deleting

a) Major equipment

b) Devices

c) Instruments

d) Soft points

4. Reporting

5. Becoming a single source for P&ID management
