Be Inspired – Thought Leadership in Amsterdam - Conference Update

Different map providers and different distribution formats create challenges in the creation of maps and the need to translate and customize layout. Tvilum said MicroStation was a “great tool” for combining different map sources.

The company uses national vector base maps with attributes from different map providers, which can be cadastral, topographical, nature and environmental maps, municipality plans and location area plans.

Before Tvilum Landinspektofirma began to use WFS, they downloaded a map only once a year, which meant the user didn’t know if any map they were using was up to date. Then they began to download and translate a map every day, which the operator didn’t like. Now they download and translate data on the fly, as needed.

“In Denmark, all national map providers deliver maps through Web Feature Services – published in GML format, and they get attributes and geometries,” said Tvilum. “I developed an application WFS booster to use in MicroStation.”

The booster works very quickly for small areas, and contains polygons and attributes.  This way, users can keep all information in one workflow and combine all different features need in a map.

Users can download parcels from an area, create a signature list, export data into Excel and generate Word documents to send out to owners.

The benefits of using WFS maps include the fact that they are current, have good quality assurance, users can download maps from different map providers simultaneously within a few seconds, they are user friendly, and users get vector maps with attributes, which allow them to make better decisions.

Result – 10 users making 500 maps per month. Without WFS it takes 20 minutes per map, with WFS it takes only 5 minutes per map.

15 x 500 = 7500 minutes =125 hours per month.

Tvilum said that users can get data into their design file in the WFS. In Denmark, environmental data is free but other types of data require a fee.

The winner in this category was a Danish company that did not present, Odense Commune, for their “On-the-Fly 3D City and Urban Modeling.”

Innovation in Utilities

Of the three finalists in this category, two were from China.

Central Southern China Electric Power Design Institute (CSEPDI)'s project manager Bailu Quan, spoke about the Jiangxia 500 kV Transformer Substation located in the Wuhan city center, where they use the relatively new Bentley Substation v8i. The $59 million project was the winner in this category.

Originally, Quan said they introduced a test project with a total investment RMB 400 million, and the project investment return rate was 7.71%.

CSEPDI’s strategy employed a combination of MicroStation J, v8i and Substation v8i to measure the minimum distance of bodies, by doing a collision check of a spheres’ electric distance. Quan said it was much easier to do an air clearance check using 3D, and they saved on land and materials by using this technology.

They have used the same technology at the Qingdao Converter Station. The converter station with the greatest capacity is Ylong Converter Station, at 7200 MW. There CSEPDI used Bentley Substation, MicroStation, Bentley Architecture, Bentley Structural, STAADPro, GEOPAK, Inroads, Navigator, and ProjectWise.

Before CSEPDI used Bentley products, they used AVEVA and Intergraph. “China is fast developing,” said Quan. “The scale of these projects is mind boggling – new technology from Bentley is in full scale production. Substation was only launched a year ago.”

Imp GmbH of Germany’s Carsten Lipinski spoke on “Reliable Point Cloud Modeling of Substations.” He said they use 3D laser scanning for asset data capture, design and management as well as for electronic towers.

“Europe is building up windpower at the North Sea, and no one lives there so they have to transport materials and build parts there,” said Lipinski. “We use Bentley Substation, MicroStation and ProjectWise.”

Lipinski made a case for how point cloud modeling can be used very effectively for retrofit projects. After the Berlin Wall came down, people found most of the building plans were Russian or East German. Lipinski said they don’t touch the old plans, it is cheaper and more accurate to go with the point cloud.

It’s a dream to have point cloud and the 3D model together, he said. 

Costs involved for 1 crew 2 people doing a point cloud capture for one substation equals approximately 8,000 euros. Laser equipment is cheap right now at less than 40,000 euros, “but you need people who know what they’re doing and the right software,” said Lipinski.

In terms of using photogrammetry to complement the inside of the building, Lipinski said there is no algorithm so far to generate the vectors outside.

State Nuclear Electric Power Planning Design and Research Institute (SNPDRI)

Located in Beijing, China, SNPDRI business focuses on developing nuclear power projects and thermal power projects, and on nuclear power and R&D. “Our goal is to develop intellectual property rights to promote reform of the energy structure in China,” said Zhu Li, director of the Engineering Center for SNPDRI.

Four design institutes participated in this project. The company has signed cooperation agreements with companies in other countries and entered into a strategic partnership with two Chinese companies. In addition, SNPDRI has participated in national major science and technology special programs research which span from the year 2006 to 2020.

SNPDRI has developed a technology platform for a large capacity thermal power project and for the trans-regional interconnected power grid. SNPDRI has adopted an advanced 3D design platform to address a number of technological obstacles.

The Ningdong – Shandong 660kV HVDC transmission project -+ 660kV level is the first power HVDC transmission project in the world, according to Li. The total investment in this project is $400 million.

For digital engineering in the first trial application in the transformer substation design project, they used MicroStation, Substation, Bentley Architecture, Bentley Structural, Bentley Building Mechanical Systems (BBMS), and GEOPAK.

The new technology encompasses the following requirements:

  • Digital engineering
  • Database is core of system
  • 3D model is core
  • Precision
  • Shortening the engineering cycle
  • Whole life memory
The Substation v8i design platform allowed omission/error checkout, soft/collision checkout and increased engineering efficiency, according to Li. They used GEOPAK for the triangle generation network. “Using Bentley software we only needed nine days to design the substation,” said Li. 

This was the first time SNPDRI had used Bentley software and wanted to see what it could do. The owners demanded the visualization and details provided by the infrastructure 3D model and now it is a requirement for all transformer substations.

Li said the used some specifications from manufacturers, and saved all the information for the 660V project, as there are “a lot of different components used in this type of project.”

Crossrail Limited

Malcolm Taylor, head of technical support services for Crossrail Limited, gave a guest keynote address on their work building a “world class building information management system.” Crossrail ended up winning the “Connecting Project Teams” category, with the other finalists also Crossrail projects.

“Data is the blood that runs through Crossrail veins,” said Taylor.  With construction starting next year, the Crossrail project will take eight years to complete.

To tackle a project of this size, Taylor said they had to create an integrated design facilitating multidisciplinary collaboration through the life of the project, which becomes the base for an asset management system, namely, in this case, Bentley AssetWise.

Mapping is a big part of crossrail – Taylor said they didn’t know that the Olympics was to be in London when they started the project, but they have to make sure that the event doesn’t impact the continuity of the Crossrail.

“The way we use data is going to change all the way through these different processes,” said Taylor. Crossrail will put 3D mapping and aerial photography on the London survey grid primary control with the inclusion of building surveys, topographical, below and above the ground data, point clouds and laser scan surveys, radar surveys, hand trace and tag surveys (rail), graphics plus associated database), environmental statement/plans, FLAB (property that Crossrail is going around, through or near – taking into account impact on land acquisitions and define boundaries in terms of what’s below and above ground and around).
