Rochester Old Bridge Refurbishment

Client: Rochester Bridge Trust
Value: £700,000

Built in 1914, Rochester Old Bridge is a Grade II Listed Structure. Jackson was contracted to carry out refurbishment works to the bridge to improve the appearance of the upstream section, by de-constructing, blasting, coating and reassembling the balustrade, and laying new paving to the footway.

Crucially, the works also included replacing corroded structural steel balustrade posts and the supporting edge-stiffener channel, a pre-fabricated ‘C’ section.

The project involved work to three spans of the bridge, and a cantilever scaffold was required over the river to gain access. Due to its Grade II listing, all works were carried out in accordance with the requirements of English Heritage.

A19/A63 Barlby Junction Improvements

Client: North Yorkshire Council
Value: £1.8m

This project involved the construction of a roundabout in place of a staggered cross roads at the A19/A63 junction in Barlby, North Yorkshire. The A19 carries over 33,000 vehicles at this location every day and the roundabout was designed to improve safety for right turners and also decrease speeds on the A19 to aid motorists coming from the A63.

The original programme for the project was 22 weeks – but by imposing a full road closure, and working seven days a week, the team managed to complete the project in 10 weeks, thus greatly reducing the impact of the project on the local community.

Without a closure construction could have taken as long as 36 weeks.

London 2012 Olympics Infrastructure

Client: Olympic Delivery Authority
Value: £11m

Jackson was included on the ODA’s Civil Engineering works framework, and carried out several enabling projects for the Olympic Games.

These included earthworks and foundations for both the warm-up track and the Waterpolo Arena in the Olympic Park at Stratford, the construction of a pedestrian footbridge at the rowing venue at Eton Dorney, and the provision of several ‘Park and Ride’ facilities across the country.

The project we’re most proud of however, is the floating walkway we constructed across Royal Victoria Dock to provide access for spectators to the ExCel Exhibition Centre. The walkway was made from floating shipping containers, linked together and anchored to the dock bed - it was one of our more unconventional designs, but the end product looked the business.

QEII Bridge Joint Replacement

Client: Connect Plus
Value: £8m

The QEII Bridge at Dartford carries 150,000 vehicles per day and is one of the busiest sections of road in the world.

Jackson recently replaced the six original multi element expansion joints, which were installed when the bridge was built in 1991.

Due to the sheer volume of traffic that relies on the Dartford Crossing every day, the team had to devise a clever method which kept the bridge open.

The solution was a bespoke designed and built temporary expansion joint, which could be installed during a single night closure over the existing joint. Work to remove the old joint was then carried out during the day, from the underside of the bridge. The new joint was then installed, again, during a single night closure which meant that disruption to traffic was kept to an absolute minimum.

Sittingbourne Northern Relief Road

Client: Kent County Council
Value: £17m

Jackson was contracted to build a 1.9Km relief road around Sittingbourne in Kent to ease traffic congestion in the town.

The carriageway was constructed across open fields, a heritage railway and service corridor, a closed landfill site and Milton Creek. The route required the construction of two steel and concrete composite bridges over the railway line and Milton Creek.

Spring Lane Bridge Reconstruction

Client: EM Highways (for TFL)
Value: £1.5m

Spring Lane Bridge is a road/pedestrian bridge in the centre of Croydon. It is a busy traffic route, and serves several vital bus routes. Due to structural issues, the bridge had to be closed to HGV’s and buses in 2010 and vital bus routes diverted around the bridge.

These lengthy diversions significantly increased public transport running costs, so in Spring 2014, Jackson began work to reconstruct the bridge.

The project presented a number of challenges. Firstly, being situated in a built up area, surrounded by residential and commercial properties, and with a live tramline running underneath, and a pedestrian footway running across the bridge which could not be diverted, the project required thorough contact, communication and co-ordination with many stakeholders, particularly London Tramlink.

The project also had various time constraints, one of the most important being the 9 day blockade period during which the tram link was shut down, and critical demolition and new bridge construction operations could take place. Despite the project starting almost 6 weeks behind schedule, the project team managed to achieve critical works in line with the blockade, and no possession works overran at any stage.
