Layher System Scaffolding
To maintain passenger access between platforms 1 and 2 during the station upgrade works at Deighton, a Layher system scaffold bridge was installed as an alternative to more frequently used tube and fit scaffold systems. This scaffolding system is centred on the highly versatile Allround Connector, which features a ‘rosette’ welded onto the upright component that can safely and securely...
Utilising a Drone with Propeller Analysis for BIM
This contractor implemented 3D digital modelling (BIM) to map out the complex coastal terrain and plan the placement of armor units with millimetre precision. They utilised a drone which flies a pre-set route which takes a a very accurate point cloud survey. This is used to programme the works, calculate volumes of works completed and void rations in the rock...
Xwatch System
Due to the proximity of some lower high voltage overhead lines the project decided to install the Xwatch system. This technology creates a virtual barrier around the plant and restricts the height that the arm of the excavator can be operated at. It also integrates with the contractors 3D design model so that the safety restrictions remain in place but...
RapidGrip Adoption on Motorway Emergency Areas
On the motorway emergency areas they have introduced RapidGrip, a highly skid-resistant, and colour-stable surfacing material developed by the Smart Motorway Partnership (SMP) Alliance. Replacing the traditional two-coat system, RapidGrip achieves bright orange visibility in a single application, reducing construction time, safety risks, and public disruption. This lean solution enhances efficiency by minimising nightshifts and traffic management, while ensuring consistent...
Trenchlite GRP Cable Trough
This contractor is using the Trenchlite GRP Cable Trough system, which provides a lightweight and cost-effective solution to precast concrete troughs. This is 90% lighter than a precast concrete trough, and brings the following benefits: Safer to transport, with fewer breakages. Easier and cheaper to install on-site GRP cable troughs can be cored on-site using only hand tools. Reduced labour,...
Female Comfort Boxes
After recently carrying out some research into female site welfare standards, one suggestion was to provide ‘comfort boxes’ in the female toilets. Alongside enhancing their minimum standards for toilet facilities following feedback from their employees and visiting clients, they also teamed up with Grace and Green who provide sustainable sanitary solutions that are not only plastic free, but organic and...
Pod Point Electric Vehicle Charger
An Electric Vehicle (EV) charger that can moved moved from site to site without the need for installation by a specific supplier. Most EV charging points are installed by suppliers and fixed on site to be removed at the end of a project. This Pod Point is fixed on a transportable mount and uses a plug and play electrical connection...
Use of BIM to Demonstrate Safe Demolition of Thames Water Infrastructure
The contractor developed a 4D animation to demonstrate sequencing and safety considerations for the demolition of a live Thames Water Trunk Sewer, whilst maintaining service and eliminating access requirements into the hazardous flows. By combining the 3D design model and the programme sequence, the methodology is clearly set out. The animation was presented to Thames Water personnel, providing reassurance that...
Marine Piling in UXO Risk Areas
The piling and civil works of the London City Airport expansion are carried out in a basin formed by the Thames River and the King George V dock. Working in this environment presents a unique constraint for the overall safety of the airport, its operations, the general public and the nearby residents, particular when using floating equipment and carrying out...
Bespoke Precast Placement Unit
The piling and civil works of the extension of the London City Airport are carried out while the airport remains fully operational. This poses two major safety and security constraints for the installation of the precast concrete units, some of them weighting up to 42 tons. As a result, installation must be done from marine spread, since security and safety...
WaveWalker
The WaveWalker is a modified jack up barge, which is capable of manoeuvring under its own power and essentially walking along the seabed. This is the first time that a working platform of this kind has been used on the UK Rail network. The contractor have modified the WaveWalker to allow the piling works to be undertaken designing and installing...
Geopura Hydrogen Generator
The contractor are in discussion with Geopura to bring a new hydrogen generator to site to replace a diesel unit, thereby producing zero emissions. There are a limited number of these units in use and only a handful of sites have trialled them in the country. The hydrogen is delivered by tanker, and manufactured using a renewable energy source. To...
3D Printed Concrete Ditch Headwalls
The project team has been looking for an alternative for the construction of ditch headwalls. The usual method is to fill hessian sand bags with concrete and place them by hand. This involves manual handling risks and working on slippery slopes while carrying the bags as well as the challenges of filling them. The site has teamed up with Weber...
Dawlish Concrete Sensors
Bam Nuttall is delivering an £25M, 16,000m3 insitu concrete sea wall at Dawlish in Devon as part of Network Rails £80M Dawlish South West Rail Resilience Programme. The new sea wall will protect a 360m long stretch of the Mainline into Devon and Cornwall, a vital infrastructure link for the region. The new sea wall project is logistically challenging with...
