Remobilisation technology & innovation
We want to share solutions and stimulate further collaboration and innovation across TfL and the wider industry.
We're not endorsing or recommending any specific product, solution or supplier - we're just sharing trials and knowledge about how the GLA's supply chain has collaborated to ensure construction work can continue safely.
Collaborate to innovate
To get construction moving again we need to work together with our suppliers to develop and implement technology and innovations that allow people to work safely.
We want to apply technology that helps monitor and advise whether a situation is safe.
We will establish a Supplier Working Group to explore and trial innovative approaches to remobilisation. If you want to be involved, email us on Remobilisationtechn@tfl.gov.uk.
Our remobilisation, technology and innovation work is focused on three key areas:
- Reduced on-site activity
- Safe on-site activity
- Remote and local
The examples on this page are aimed at either enabling activities to be done remotely so that there is no need to go to site or, if people do need to work on site, to improve and/or monitor safety.
These technologies are either currently in use or are are undergoing trials.
We are working together with suppliers to implement these solutions:
Thermal cameras measure body temperature to a high degree of accuracy in real time and can track people with high temperatures within a crowd. The system issues notifications of fever detection and footage can be viewed live or via playback.
We're using mapping drones on the Barking Riverside extension to provide real time images to help us supervise and inspect the spacing requirements. The drones also allow remote access to areas people could not get to while maintaining a two-metre social distance.
The device captures high-resolution aerial photos that can be transformed into accurate orthomosaics (maps) and 3D models. We will use the drone for key activities like piling works inspection, reinforcement installation, virtual walkthroughs of sites and completion of safety tours.
See an example of the output from the devices on the Roundme website.
You can also see a demo of the eBee mapping drone on the Sensefly website.
Hands-free door openers
We're exploring the feasibility of using hands-free door openers to minimise contact with door handles that may harbour dangerous germs.
Two 3-D printed pieces are secured with screws over existing door handles. People can then use their forearms to open doors rather than touching the door handle itself.
Find out more about hands-free door openers on the Materialise website.
Video conferencing technology
We have been exploring opportunities to use existing, readily available video conferencing technology embedded in mobile devices to reduce on-site activity.
On the Bank Station Upgrade project, we worked with our supplier Otis to use video conferencing technology to remotely witness escalator testing in a factory in the Czech Republic.
On the Four Lines Modernisation (4LM) project, programme leaders have been using video conferencing technology to talk about safety with staff on site.
Digital video cameras
Small digital video cameras allow those staff who visit a site in person to create a video record of their visit. Files from the video camera can be stored on the network and accessed by other project team members, reducing the need for people to go to the site.
The 4LM programme has been using this approach to offer an overview of work sites and to do safety tours, inspections and other engineering activities.
We are evaluating OCULO. OCULO uses a helmet-mounted camera to capture a walkthrough of a construction site. The data from the camera is combined with floor plans and other data by the OCULO software to produce an interactive 3D model of the work site. Multiple users can then interact with it and use it to support virtual inspection of sites.
Find out more on the OCULO website.
We are reviewing Sitestream, a system that combines HD cameras and software to build an interactive timeline of construction. Sitestream captures 10-minute HD clips of the site and indexes these in a software package.
Users can use the software to review work on site and identify if there are any issues with social distancing.
Find out more about Sitestream on the Site-Eye website.
We use the Sentry System on our Track Partnership work sites. The system comprises four camera units which work together to capture an entire site with a high degree of timing accuracy.
The feed from the cameras can be viewed remotely to review progress and monitor social distancing.
SiteZone Personnel Distancing System
This system comprises a detection tag that alerts the wearer when they are less than two metres from another person. The system is being tested on the DLR East Route possession.
Find out more on the SiteZone website.
Geographical Information Systems
A Geographical Information System (GIS) is a powerful tool used to capture, manage, analyse and display information with a spatial reference. GIS can visually represent data from several different sources and provide an intuitive front end to existing IT systems. Layers of data from various sources are brought together into one hub to help us better use our data and remobilise the workforce in new ways.
Our GIS systems support rail, Underground and surface transport activities and combined have over 1000 layers of data, all of which can be accessed by staff through an easy to use map.
- Station models
- Asset locations
- Flood Risk and other hazards
- Environmental datasets
- Project work locations and timescales
Construction site mapping
Over 250 TFL and other construction sites around London have been mapped using GIS. The data can be used alongside hundreds of other useful datasets available in GIS, allowing users to visualise sites with the highest numbers of mobilised workers and put construction sites in their local context to understand issues such as travel demand.
Station TruView data
We have done TruView surveys across several stations, covering different station levels and rooms and some sections of track.
Survey data is put out as a pointcloud which can be used to generate images giving users an immersive experience that they can navigate around. The user can also use TruView data to take measurements and identify coordinates.
On the Silvertown Tunnel project, we collaborate with Riverlinx through TfL's Common Data Environment. This consists of Asite (for document and non-graphical data) and ProjectWise for graphical data.
The Common Data Environment is the single source of information used to collect, manage and disseminate documents and graphical and non-graphical data to all the project teams.
Design teams can create a fully coordinated digital model to use when building the physical asset once work is arranged to start on site. Project stakeholders can collaborate and communicate using Cloud-based applications, granting access to the project's Common Data Environment.
Digital workflow management allows different participants to access information in certain stages and participate in the design review and approval process.
Barking Riverside and White Hart Lane
For these projects, we're hosting a ProjectWise environment that can be accessed remotely. The ProjectWise environment includes digital workflow rules that allow information to be shared, reviewed and accepted at each project stage and by all project participants.
ProjectWise enables project dashboards that provide visibility on the progress of design deliverables. This information is shared with external stakeholders using the Project Shared function.
