M6 Bridge Demolition

M6 Bridges, Lancaster

16th February 2018 By No Comments

Location: M6, Lancaster
Client: Highways Agency / AMEC
Planning Supervisor: Lancashire County Council
Principal Contractor: AMEC
Timescale: January 2003 to February 2003
Value: £100,000
Scope: The demolition of 2 motorway bridges over 2 x 12 hour weekend possessions of the M6 motorway, removing foundations and re-opening motorway.

Demolition Overview

The demolition of two bridge which carried motor vehicles over the M6 between Lancaster and Carnforth proved to be very demanding projects. The bridges were to be demolished because of concrete decay and were to be replaced with two new ones. Working closely with AMEC Capital Projects and the Highways Agency we were given two dates to carry out the demolition.

The bridges were constructed from pre-stressed, post-tensioned concrete beams, so the demolition had to follow a pre-designed sequence, which had been specifically designed by a structural engineer.

The demolition had to take place on two Saturday night 12-hour possessions and the bridges had to be demolished by mechanical means.

At 8:00pm, the motorway was closed and FDL installed the carriageway protection, consisting of a geo-textile membrane, plywood sheeting, a 750mm layer of crushed concrete and hundreds of wagon tyres.

Once the protection was in place, we demolished and cleared away the bridges with the use of four excavators of various sizes, fitted with 360o rotating sheers & concrete pulverisors and a fleet of 15 wagons. The operation ran smoothly and the motorway was re-opened on time at 8:00am Sunday morning on both occasions.

``I have worked with FDL on my last two projects with the most relevant being the demolition of Lincoln House and 123 Deansgate to allow the development of a new £50m commercial development. We found FDL to be commercially aware without being aggressive and easy to work with contractually. I might add that on the back of Deansgate FDL also demolished a very sizable office block to the rear of our building for Marshall CDP, Brazennose House, which was also a complex building as it was a mix of precast and insitu concrete and not in the best of condition! They have just finished working with me on a £25m refurbishment project in central Liverpool which is a Grade II listed hotel development. While a very different beast it is no less complex in different ways``Deansgate

``Forshaw Demolition were employed to demolish three high rise block of flats, by explosives. I was the Contract Administrator for the works and I found them to be impeccable in all aspects of the work. Nothing was too much trouble for them and they always wanted to please. Their organisation skills are second to none, that is why I have used them on numerous occasions. They are my first port of call when anybody within Preston City Council mentions demolition.``Preston City Council
