Increasing Efficiency and Accuracy in the Planning and Execution of EPC Projects

as-built survey would first need to be conducted. SB SETEC decided that this project was an ideal candidate to execute with a “fully digital” approach. It was clear that using laser scanning in combination with 3D plant design was the only way they could achieve the tight project deadline in combination with the spatial design challenges.

SB SETEC searched for a solution to digitalize their workflows to increase productivity and efficiency.

2019 was a robust year for many EPC (engineering, procurement & construction companies), with growth the ever-growing complexity and size of projects driving the companies to improve their project planning and execution. According to Deloitte’s 2020 Engineering & Construction Industry Outlook1

, the bottom lines of EPC

companies are still under considerable pressure even though firm revenues are growing steadily. Most of the challenges met by EPCs in 2020 can no longer be facilitated without a digital approach: a need for more integrated project execution systems that allow better visibility and planning, growing complexity of projects and ongoing cost pressure.

This article looks at a real-life user case from SB SETEC, a leading Italian EPC company, that increased their efficiency and accuracy of EPC project execution with the help of Hexagon’s PPM Division.

Identifying project goals

SB SETEC is an Italian engineering and EPC service company which has been operating in industrial plants since 1970. To further improve their project execution, the company was searching for a partner that would help them to digitalize their workflows using user- friendly tools that integrate reality capture along with engineering and design processes. This would enable


increased productivity and efficiency during all phases of the typical revamping projects they undertake, supporting more economical project execution.

For this specific project, SB SETEC was selected by a large Owner Operator client to revamp their Sulfolane process plant to improve performance. The highest tier of an existing steel structure had to be dismantled and redesigned in order to place new equipment and new pipelines into the facility.

Overcoming Challenges

After a preliminary review of archived drawings, SB SETEC determined that an

SB SETEC had to find a solution that would enable the project to be completed quickly with an error-free re-design, that once constructed would work with the existing equipment and piping in the plant. Additional interference checking needed to be performed during the design process. This was due to spatial complications which had the potential to introduce clashes. An overriding challenge was also to ensure health and safety standards were maintained, and production was unaffected whilst detailed plans supporting the refurbishment were being designed.

After extensive evaluation of solutions, SB SETEC embraced Hexagon’s PPM Division’s CADWorx®

design software and CAESAR II®

DWG-based plant , pipe

flexibility and stress analysis software to execute 3D design and code checks.

SB Setec used Hexagon Geosystems’ RTC360 laser scanner to survey the existing structures of the sulfolane plant. 21
