EPC ENGINEERING DISCIPLINES

EPC Engineering Disciplines•Process•Mechanical•Civil•Plant Layout•Piping•Electrical•Instrumentation and Controls

EPC Challenges Execute EPC “mega-projects” within budget

and on scheduleMinimize construction delays due to lagging

information, material or equipment.Track progress and maintain contingencyplans to stay on schedule.Document project progress in terms of

installed quantities.EPC ProjectsBy Robert N. Fox

The Challenge• Intelligently apply IT/CAD to the EPC

environment.• Overcome conservative mind-set of builders.• Push progression of 2D to 3D, 4D and even 5D.• Apply IT/CAD tools to the advantage of

constructors and their clients. Better productivity leads to better gross margins.

CAD HISTORY

Levels of Modelling• (Data) Custom made forms• 2D Drawings and Sketches (E)• 3D CAD Model with data attribute links (E)• 4D Construction Simulation Model (EC)

– 4Dc –Construction Planning & Sequencing– 4Dr – Resource Management (and Lift Plans)– 4Ds – Construction Status

• 5D Cost Tracking Model (EPC)– 5Dm: material costs– 5Dr: resource costs

EPC ProjectsBy Robert N. Fox

2D Drawings and Sketches

• Traditional format• Inter-drawing design coordination subject to error• Change management requires rigorous document

control process.• 2D CAD used for nearly 30 years aids in drawing

format consistency as well as storage and management of drawing files.

“Intelligent” 3D CAD Model

• Used for EPC over the past 20+ years (3DM, PDS, PDMS, Smart-Plant, Plant-Space)

• Requires changes to traditional work processes• Component attribute data is the “intelligence”• Clash Checking• Automatic Drawing Creation• Material Take-Off Reports• Data Consistency Reports EPC Projects

By Robert N. Fox

4D Construction Simulation Model• Links 3D model components with P3

schedule• Assigns temporal dimension to each

“widget” in the 3D model• Facilitates Construction Operations:

• Construction Sequencing• Resource Management Planning• Constructability Assessment• Lift Plan Verification• Visualization EPC Projects
