GIS from Esri UK helps coordinate 8,000 workers on 450-acre site  EDF has used enterprise GIS from Esri UK to create a geospatial portal for Hinkley Point C (HPC) nuclear power station, one of Europe’s largest and most complex construction projects. Supporting better collaboration and enabling new digital workflows, the portal is sharing a single view of the entire project, helping employees and contractors work seamlessly and improve safety and productivity. Recently opened-up to include Tier 1 contractors when construction of the nuclear reactors started, the portal now has over 1,500 users. Currently one of Europe’s largest construction projects with 8,000 workers on the 450-acre site, Hinkley Point C is the UK’s first new nuclear power station built since Sizewell B in 1995. The nationally significant infrastructure will provide around 7% of the UK’s electricity, power around 6 million homes and contribute to the UK Government’s Net Zero target. Central source of data Delivering clarity of information, the GIS portal is a central source of all spatial data, maps, apps and dashboards, combining multiple sources of information and making them accessible to everyone on site. An interactive primary site map contains over 100 different data layers, from BIM models and CAD data including Revit models, to construction operations, temporary works, utilities, logistics and emergency preparedness. “The scale of the project presents a complex logistical challenge,” said Jon Dolphin, Construction Project Manager and GIS Lead at HPC. “Clarity of construction data is critical and the GIS portal provides a single view of this, which drives collaboration as people can see where things are happening and when. Every employee or contractor is making decisions based on the same data. The confidence this generates makes decision-making faster and strengthens the ability of teams to work more efficiently. As a result, we’ve seen improvements in quality, safety and productivity.” Starting life as a proof of concept three years ago, the GIS portal first became an enterprise roll-out in Spring 2021 and has grown since then. “Small pilots showed what was possible, helping a wider audience understand the benefits of using GIS on a megaproject,” explained Dolphin. “Users now browse the spatial data, explore applications and enable new digital workflows relevant to them. The number of portal users is growing daily as more people become aware of what GIS has to offer and more use cases emerge.” Digitising workflows Esri GIS has enhanced HPC’s ability to collect data out in the field, replacing manual methods using paper checklists, clipboards and spreadsheets. One example is emergency planning data, used to provide assurance for regulatory purposes, which is now collected on tablets and appears in real-time in the GIS portal. Managers view and report on it using dashboards, helping to make more informed decisions. Temporary Works teams use similar new digital workflows, for planning and inspecting hundreds of simultaneous works, including excavations, earth works, scaffolding, ramps or form work for reinforced concrete pours. Adding the spatial context means contractor activities do not clash while physical surveys now take a fraction of the time. Using GIS apps and integrated dashboards for data input and reporting, eliminates the need to transfer information into a report when staff return to the desktop. Mobile GIS Another example of mobile GIS in action is an app created to improve the management of generator permit requests. HPC needed to monitor emissions as the site grew and wanted a detailed understanding of generator use. Now contractors have the ability to use a new mobile app instead of a spreadsheet, to click on a location and request a generator which is submitted into a workflow for approval. A dashboard displays the data so electrical and environmental teams can optimise the use of generators and reduce emissions across the site. “The new digital approach has replaced the previous spreadsheet-based system, which lacked auditability and had no spatial context,” said Dolphin. The portal will see another increase in usage when the MEH phase (Mechanical, Electrical and HVAC) ramps up in 2023, to manage permitting and controlling what is being built on site. This phase will see contractors work together on the complex installation of cabling, pipework and equipment for the power station’s 2,500 rooms. Future plans include using GIS to track and optimise the use of plant around the site to reduce emissions and make transport services more intelligent, by tracking the site’s buses and other vehicles. “Having one GIS portal for our construction data is immensely powerful for breaking down communication barriers, getting everyone on the same page and improving collaboration,” concluded Dolphin. “The use of Esri GIS at Hinkley Point C was a cultural shift for many people but new digital approaches soon become indispensable when working on such complex engineering projects.”

LSBUD, the UK’s leading online safe digging resource, finished 2022 with 3.75 million search enquiries for underground pipes and cables passing through its central system. This is a 12 percent increase on the previous year. The portal also registered 43,190 new Users in 2022. This represents a 14 percent increase compared to 2021, and is 35 percent up on 2020. Richard Broome, MD at LSBUD, comments: “In 2022, our portal received more search enquiries than we take breaths. It’s absolutely extraordinary. At the start of 2022, our aim was to break through the 3.5 million enquiries barrier, so to achieve 3.75 million is credit to those safe digging industries who are more committed to best practice than ever before. “People operating within the farming, construction, highways, telecoms, water, gas and electricity sectors need to be praised for their part in this substantial growth, as do UK consumers who are increasingly undertaking home projects with greater care than ever before.” Growth in coverage was also seen across all industries, in particular the gas sector, with Northern Gas Networks joining the collaborative portal in 2022. This means LSBUD now has complete coverage of the UK’s major gas distribution networks, with 100 percent of them collaboratively sharing their data on the free-to-use, central portal. Fibre networks also jumped on the safe digging momentum, with Voneus, Ogi, Wildanet and Toob joining the likes of broadband key players Gigaclear, Gamma, Neos Networks and Zayo, in recognising the importance of having their asset data shared on a central portal. Richard Broome concludes: “2022 was the best ever year for the safe digging community. Pipes and cables were better protected than ever before, and those working near them were safer. Of course, there is room for improvement, and that is what we push for, however we wanted to extend a thank you to every farmer, construction, highways, telecoms, water, gas and electricity worker, that searches before they dig. It is good practice, it is safe, and it is sensible. Remember, always search before you dig.” For more information about LSBUD, visit http://www.lsbud.co.uk/ Building, Design & Construction Magazine | The Choice of Industry Professionals
