Project Difficulties and Restrictions

The project required the installation of 750mm diameter piles in restricted access and low headroom conditions beneath the existing Power Road bridge to the busy A406.


The A406 was required to remain open with minimal disruption to traffic whilst works were being carried out, and hence necessitating foundations to be installed below road level.

 

The concrete needed to supply the piles had to be pumped 160m via concrete lines which also had to cross over the Power Rd Bridge.
 

The Martello Solution

Martello utilised their MP4000 Low Headroom System to carry out the construction of the 750mm diameter piles beneath the existing bridge in 4.8m of headroom, enabling foundation works to be undertaken without disruption to the A406 traffic flowing in and out of London, and thereby easing congestion.

Specific Project Features

Piles were required to provide foundations for a new reinforced concrete bridge to replace the existing Power Rd Bridge and span over the Broad Street to Old Kew railway.  

 

Owing to the access restrictions on the south abutment all plant and equipment had to use a road-rail access point crossing, to carry out the piling works.

 

As part of the same TFL infrastructure package to upgrade existing bridges  , Martello also carried out similar piling at Ardleigh Green Bridge.

Future Potential

The Martello MP4000 large diameter and low headroom system can negate the need for existing structures to be demolished prior to piling works being carried out. This in turn can lead to less disruption to the local environment and pedestrian and vehicle movement can be kept to a minimum.
