The ‘Fiveways’ scheme in Croydon aims to tackle congestion at the A23/A232 junction and surrounding network, improving it for all road users. It includes the Purley Way interchange, Fiveways Corner junction, and Waddon Station Bridge, and is important for the borough’s economic growth.
Brighton Pier is a Grade II* listed building which opened in 1899. The pier head comprises structure from three distinct periods. The central core is constructed of Victorian cast iron screw piles while to the northeast corner is an area approximately 35m x 15m known as the boat deck and built in the 1930s. In the mid-1990s, the pier head was then extended, with a new structure surrounding the original construction.
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 ...
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.
When Gibraltar's airfield approached its due date for major planned refurbishment works and upgrade, Ramboll was appointed to provide management, technical and financial services to the project, which was the first full runway re-surfacing in 20 years.

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.

In the heart of Kings Cross and dating back to 1875-1895, the Lighthouse building is a local landmark. It was left derelict for many years until developers; UK Real Estate took the bold decision to redevelop the Grade II listed building that was on Historic England’s Buildings at Risk Register.
Ramboll specialists were commissioned to undertake detailed laser scanning surveys of 52 of the 53 stations on the Piccadilly Line, one of London Underground’s major arteries.
Baltimore Lifeboat Station, on the south west tip of Ireland, has been extended and remodelled to accommodate the needs of crews for the inshore and all-weather lifeboats. Facilities have been improved further by creating an adjacent pontoon berth. Our team provided geotechnical, marine, structural and building services engineering and project management.The station building (c.1913) is an early example of reinforced concrete construction and has been refurbished and enlarged by the addition of a new steel frame extension, roofed with slate to match the existing. The station’s slipway has been modified so that RNLI Baltimore’s Atlantic 75B class inshore lifeboat Bessie can be launched directly from the boathouse. A water-source heat pump uses seawater to supply backgro ...

TfL is replacing the three span Power Road Bridge, which carries the A406 North Circular Road (Gunnersbury Avenue) over two Network Rail lines. This complex project involves diversion of utilities onto a new service bridge, and highway bridge deck demolition and replacement works without the need for road closure.
The London 2012 Summer Olympic and Paralympic Games was Britain's largest peacetime logistical exercise and a major challenge for Transport for London (TfL). London's road network had suffered decades of under-investment preceding TfL’s ownership, and the highest priority structures had to be in a state of good repair before the Games began.
Highbury Corner bridge in central London was one of the eight highest priority structures on Transport for London’s (TfL) road network that were identified as needing intervention and investment. It had to be replaced to reduce the need for disruptive emergency closures in the future. Despite unusual complexities and constraints, full deck replacement took place with only a 20-day road closure and a 195hr rail possession.
