project delivery mechanism for optimizing project cost

and quality

Operation &

Maintenance

Ensures that designer is

ultimately responsible

for quality performance

Higher plant

operation efficiency

Continued client

interaction

Least downtimeHigher efficiency due to

in-depth understanding

of assets created

Preparation of AMP

(asset management

plans) for optimizing

O&M activities

Technology

Planning and

technology

selection is

usually the most

critical step

Requires in-

depthunderstanding

of technology

and design

factors
