Insider blog: Could you tell us a little bit about your company and some of the latest projects you have executed with Intergraph solutions?
Ciaran McCreary: Mercury Engineering is a leading European contractor specializing in the provision of mechanical, electrical, fire protection and technology services to a range of sectors including commercial, data centers, manufacturing, infrastructure and healthcare.
One of the latest project examples to share could be a project we executed for an existing process plant a little while ago. We were contracted to upgrade an existing process plant located near to Groningen, in the Netherlands. The project scope was the design of a new process plant with product pipelines that needed to connect into an existing facility. To achieve this, it was necessary to route the new pipelines along an existing pipe bridge, and across the roof of the existing structure and into a new building.
IB: What were the biggest challenges you met during the project?
CM: Unfortunately existing as-built information was lacking, therefore the initial challenge was how to capture the as-built situation quickly and accurately. To ensure successful on-time project delivery, we determined that it would be necessary to laser scan the existing building, roof space, and pipe bridge. This would provide an accurate design basis for the new pipe routes and tie-ins that had to be designed. Having this information available would also help to ensure and guarantee that the new piping would fit on the pipe bridge and could be constructed inside the existing building without clashing.
IB: What were your main project steps?
CM: We paid particular attention to the tie-in points, and extra scans were done in these areas to ensure that enough detail was captured to accurately design the tie-ins. After this, Leica CloudWorx in combination with Intergraph CADWorx Plant Professional was used to manipulate the piping route to match the scanned as-built positions of the new tie-ins and to accurately design them. Visualization of the pipe bridge inside the CAD system helped to identify space for the new pipelines, enabling them to be routed easily alongside other existing services, which made connecting the old and new building seamless.
The pipework installation was detailed before the new building was constructed. As the building was being erected and took shape, it was laser scanned, and the new point clouds were integrated with CADWorx Plant Professional.
Using CloudWorx in combination with CADWorx, we were able to make minor modifications to the pipework as the project was on-going, to align the routings and to make changes to the overall design to reflect the changing as-built condition of the new building.
This additional site-check increased confidence in the accuracy of the isometrics issued to the fabrication workshop, which were auto-generated via Isogen directly from the CADWorx design model. In doing so, we ensured that the piping would fit first time, and avoided unnecessary fabrication rework on-site, helping to keep the project schedule on-track.
IB: What were the biggest benefits you experienced using CADWorx & Analysis Solutions?
CM: We received significant benefits from using Intergraph’s CADWorx solution on the project:
• Schedule certainty due to ability to track progress better.
• Ability to design and build Right First Time due to access to accurate as-built data inside the CAD environment.
• Reduced labor onsite due to the ability to generate high quality isometrics, which helped to avoid the need for on-site fabrication.
