DJI drones and site survey software improve £ 7 billion development workflows – heliguy ™


  • Major development in London benefiting from DJI drones and Site Scan software from Esri UK;
  • Software that transforms drone data into valuable digital assets, such as 3D point clouds and 360-degree aerial panoramas of the site;
  • These assets streamline and improve field surveys and project-wide communication;
  • Software is also used to plan and manage flights, which makes the drone program more coordinated and easier to manage;
  • heliguy â„¢ has partnered with Esri UK to deliver an end-to-end workflow for the AEC industry.

A £ 7 billion development in north London benefits from DJI drones and GIS software – improving efficiency, site-wide communication and decision-making.

Brent Cross Town, a joint venture between Argent Related and Barnet Council, combines unmanned aircraft – including the Phantom range – with Esri UK’s Site Scan drone image processing and flight management software.

The software is used to create 3D point clouds, textured meshes, videos and 360 degree panoramas – using data collected from drone images.

These digital assets make it possible to share very accurate and consistent updates among all stakeholders as development progresses, and to increase the speed and safety of earthwork surveys, such as volume calculations of stock.

Lily Wydra, GIS, Land and Property Manager at Argent Related, said: “The deployment of drones and Site Scan in Brent Cross Town has streamlined the way we survey, visualize large-scale developments and communicate progress. of the site.

The case study was shared during a joint speech between Esri UK, Ben Sangster, GIS manager of heliguy â„¢ (photo below), Argent LLP and Galldris Services Ltd during Digital Construction Week. heliguy â„¢ has partnered with Esri UK to provide the AEC industry with a comprehensive set of hardware, training and software.

Drone surveys allow a more consistent and efficient progression of the site

A new park city for Barnet and London, Brent Cross Town is an ambitious 180-acre new neighborhood, featuring 50 acres of parks and playgrounds.

With 6,700 new homes and 3 m² of offices for 25,000 employees, the city will be a major new office destination. New sustainable transport links, a main street, proximity amenities, world-class sports services and facilities are also part of the program.

Previously, drone surveys were commissioned from third parties on an ad hoc basis, with results defined by the business objective they met, such as project management, logistics planning, marketing, or legal.

However, the Brent Cross Town team wanted to create a more consistent and efficient method of tracking site progress and making it easier to manage the overall drone program.

Lily Wydra, GIS, Land and Property Manager at Argent Related, said: “Before Site Scan, we didn’t have any pre-existing software specifically for flight planning or managing and processing drone image outputs. We now have a cohesive framework to manage all flights throughout our supply chain, process the images, create high-quality geospatial outputs and disseminate them to multiple stakeholders.

“As a cloud-based service, Site Scan also means that we can work seamlessly with sub-contractors, such as civil engineering contractor Galldris Services Ltd, who we have currently asked to do work on. drone study. “

Galldris’ drone team regularly performs drone surveys with its fleet of DJI drones and has been using Esri Site Scan under the Silver Operator License, since March 2021. This includes flight planning through software.

Galldris also helped maintain part of the GCP (Ground Control Points) network to help self-georeference drone images.

The team now processes the monthly drone releases to support internal operations and delivers them to Argent who uses and disseminates them through a collection of ArcGIS Online maps and apps.

Outputs include 3D point clouds which have helped construction managers, engineering teams and contractors understand how changes in site topography will impact the site and perform volumetric calculations, on the amount of earth to be excavated and removed.

Meanwhile, videos, static images and 360-degree panoramas were used to provide project teams, investors and the public with engaging visual updates on construction progress and by legal teams when ‘they are working on leases with potential tenants.

Wydra added, “Site Scan has allowed us to create a formalized and repeatable approach to generating digital drone outputs regardless of the survey provider, which is also more cost effective than ordering ad hoc surveys.

“The use of drones is increasing, so having a scalable framework to manage flights and streamline the integration of captured data into GIS, BIM and CAD workflows is invaluable. Ultimately, better drone outputs support a better data-driven decision-making process. “

Transform construction workflows with site analysis

Site Scan seamlessly connects to Silver Related’s enterprise GIS, Esri ArcGIS, and already enriches geospatial datasets.

Drone data can be quickly published to ArcGIS Online to enhance pre-existing online maps, including those on-premises or shared with Barnet Council, which has started publishing some data layers in its master plan.

Regular drone surveys have also proven invaluable in monitoring progress remotely during COVID-19 shutdowns, when access to the site was limited. They also provided other information, such as the elevation of the site throughout construction, as shown in the image below.

Brent Cross Town is the first Argent-related project where Site Scan has been deployed, but the development company plans to use it in other major developments, including King’s Cross and Tottenham Hale, as demand for data from drones are increasing.

Wydra said: “Engineering is a precise school of activity and drones are a relatively new part of the workflow, but they are now working alongside proven engineering practices and surveying activities.

“Site Scan is helping to create a more coordinated and efficient way to manage our drone programs and will move on to other developments soon as we expand it across the company. “

Heliguy partners with Esri UK for end-to-end workflows

Drone specialist heliguy â„¢ has partnered with Esri UK to develop an end-to-end drone solution for the AEC industry.

The alliance provides a complete workflow for aerial surveying drones, bringing together the heliguy â„¢ drone industry’s multi-faceted approach to consulting, material supply, pilot training (including including GIS) and internal repairs and R&D, with existing flight planning, Esri data capture, data processing and GIS software – centered on Site Scan for ArcGIS.

The partnership is designed to offer a compelling solution to large AEC organizations looking for integrated and scalable drone programs.

It aims to streamline current processes, from drone management and data capture, to better sharing of results within a company and integration with BIM and CAD workflows.
