Condor Projects Ltd. has successfully completed one of the toughest challenges to date.

After 30 years of specialist contracting, Condor Projects Ltd. has successfully completed one of the toughest challenges to date.

On an asbestos contaminated slope in the high Pennines, Condor Projects Ltd were contracted to stabilise a bank to prevent slip, cover and shield the area from further loss of asbestos waste.

Conditions at this site made the work particularly difficult. Having started during the summer of 2017 to complete the work before the cold of winter, the level of contamination was found to be so bad that programme was suspended for over 4 months. Unfortunately, this pushed the anchoring back into the depths of winter, not a place to be working during the freezing conditions of a Yorkshire winter.

To compound the problems, the immediate area in and around the site was surrounded by thick woodland and a late imposition of a weight limit of 1500 kgs meant using equipment on the limit of their capabilities. Furthermore, the site was located on a steep incline, of up to 45 degrees. Again, this significantly limited both the capability and type of machinery available to complete the project.

Prior to any work commencing, our specialised drilling team had to undergo intensive asbestos awareness training. This prepared the team and ensured the safety of everyone in the local area. As a result of dealing with this level of contamination, it was imperative that the drilling team wore disposable, full body protective suits at all times with a full-face respirator. Further to this, every individual who visits the site must pass through a full decontamination unit with a shower before leaving the area.

As ground stabilisation specialists, we were able to provide a solution which is appropriate for the bank but which also worked around the given circumstances. Stabilisation of the bank was completed in April 2018, involving pinning the bank with soil nails and pattress plates, and then ultimately protecting the bank with a mesh.

Although progress was slow, as a result of the decontamination process and the extreme freezing weather conditions, work was completed with only a short extension to the programme period.
