CAWARDEN THREE TOWERS!

Cawarden Co Ltd, Midlands and Welsh NFDC members, have recently undertaken the demolition of three 30 metre plus high towers, all of dissimilar structures and each one requiring a different technique to ensure they were removed safely, on time and as instructed by the client.

Each tower removed by Cawarden was at a separate location and in completely different surroundings.
 
Tarmac Mixer Tower

This was the first to be undertaken in January 2013 and was situated within the live Tarmac Plant near Swadlincote, Derbyshire. The contract was for Tarmac PLC and their specification consisted of removing the top 15 metres of the mixing tower, cutting out internal plant and services, and leaving the steelwork cut to an angle that would allow the remaining structure to be over clad.
 
Parameters of this building included having other buildings all around the tower, with a second twin tower at a distance of only 30 metres. Railway lines lay some 50 metres away and machinery was still in use inside the first 20 metres of the tower to be taken down. After meeting with Tarmac engineers, Cawarden's method of works were agreed by both parties and we were advised, by the way, it was a nesting site for peregrine falcons so the whole project, including the re-roof, had to be completed by the end of February!

The basic method was:
  • Cut away the external roof structures
  • Cut away part of the roof
  • Cut out all internal equipment and remove from the tower using a small goods lift
  • Prep cut the upper structure and alter a lift design
  • Lift the structure from the remaining tower using a mobile crane
  • Cut up the structure at ground level and remove it from site
Our Site Manager Mick Whitehead said the biggest problem they had was the extreme cold and high winds, which did delay the final lift by one week, otherwise all went to plan.
 
South Staffs Water Tower

The second tower was undertaken by Cawarden in July 2013 and was situated in a rural location near Cresswell in Staffordshire. This water header tank stood in the middle of fields accessed only down a long narrow private drive, which led to a house situated 60 metres from the 30 metre high platform with a 20m x 15m Braithwaite water tank sat on top. Staffordshire Water had no access into the farmer’s field and one boundary fence was situated at the base of the tower. On no account must we allow any steel, rust etc. to drop into the farmer’s field and we were asked to take it down ASAP.

Cawarden could only get a telehandler and a lift up to the tower and the steel had to be removed in swing skip bins. The method in this case was:
  • Cut away all external fittings, water pipes, ladders and cables
  • Access the tank using cherry pickers and oxy propane cut the tank lowering the steel via a high reach    teleporter
  • Place the steel into 10 yard skips and continue until completion
The Site Manager and Top Burner, Malcolm Lowes' only comment was that the summer heat meant that operatives rotated the cutting times due to fatigue and heat exhaustion with having to wear all the heavy PPE.
 
Tarmac Cement Tower

The third tower situated in the redundant concrete panel plant at Kirkby in Ashfield, Nottinghamshire was demolished in September 2013. The 30metre tower this time was more straight forward, standing in the redundant 12 acre site the whole of which was to be demolished and the 1000 tons of scrap processed.

The method was standard and simple:

Using a Komatsu 450 high reach the tower would be sheared to the ground.

However, after eventually accessing the tower it became apparent that due to extensive vandalism parts of the structure would need to be done by remote demolition as they could fall in an uncontrolled manner. These parts were removed and the high reach could then do its work. Darren Sheldon, the Cawarden high reach driver, said it was ‘all in a day’s work’, ‘I love these challenging structures!’
