Gantry product design for smart motorways

Innovation in digital gantry design has been pivotal in the development of Highways England’s Smart Motorway Programme (SMP). Ramboll provided the step change needed to deliver the quantity and quality required through automating the design process.

Hammersmith Flyover - Phase 2 refurbishment and strengthening (HFO2)

Phase 2 strengthening of the Hammersmith Flyover (HFO2), was a phenomenally complex £100m programme including innovative engineering solutions to install a full new prestress without removing the original. With 70,000 users every day on a key strategic route into London, the structure, which had been deteriorating due to significant corrosion, presented many technical, logistical, programme and political challenges.

Llantysilio Chainbridge restoration

Thought to contain the oldest wrought iron chain links in the world, this bridge project has transformed a derelict and unsafe site into a safe, functional structure that is a major tourist attraction.

Daniel Shearing. Ramboll engineers undertook a detailed visual inspection of Hastings Pier. The 12m high Grade II listed sub-structure was difficult to survey because of its size and complexity and limited access from the beach, which depended on the tides.

Arnside Viaduct deck and rail replacement

Built in 1856 — and rebuilt in 1915 — the 51-span Arnside Viaduct carries the Carnforth to Whitehaven railway over the River Kent estuary at a point close to Morecambe Bay. Its deck had suffered considerable deterioration and Network Rail decided to replace it. Our transport engineers undertook a Grip Stage 5 (Form B) design for the superstructure, working closely with contractor May Gurney.

Brighton Pier. Ramboll produced a highly buildable design for the replacement of the substructure at the pier head fully mitigating any pier closure, halving the whole project cost and were awarded an ICE Health and Safety Award for producing a low risk easy build design

Brighton Pier boat deck replacement

Brighton Pier, on the south coast, has undergone numerous alterations since it first opened in 1899. The Grade II* listed structure is 540m long and consists of a stem and head that date from three distinct periods. The 1930s ‘boat deck’ — an area approximately 35m x 15m in size — was found to be in poor condition. Our marine structural and geotechnical engineers were employed to design a sympathetic replacement scheme.

Awkward access and a lack of accurate records made it difficult to identify the boat deck’s composition. Modern laser scanning techniques helped determine the existing geometry. The central core of the pier is its grid of Victorian-era cast iron screw piles. In the mid 1990s the pier head had been extended and the new structure surrounded the original. Adding to ...
