OHSAS 18001 2007

In theory the attainment of OHSAS 18001 2007 should serve to provide a springboard for any organisation to expand their market share via clearly being able to demonstrate to potential clients their proven and documented approach to health & safety in the work place.

However the sad truth is that organisations including blue chips fail to fully grasp the importance of such an accreditation and those that do are slow to promote a preference to working with companies who have achieved OHSAS 18001 2007 throughout their organisation.

This can be vey frustrating, listening on one hand to organisations promoting their values and approach to H&S but in reality experiencing their failings in ensuring companies holding such accreditations are actively promoted from within.

The most frustrating scenario is the one of familiarity, often large blue chips operate as satellites and the selection of a contractor can often be purely based on experience e.g having used a particular company for years.

Regardless of this Churchill Steeplejacks are still very proud to be the first Steeplejack company to be accredited to this standard.

Concrete Chimney Demolition

The removal of 3no 60m steel flues from within the reinforced concrete windshield at the old Roche site in Welwyn Garden City was safely completed with the use of a 300 ton mobile crane.

The 3no flues were removed to facilitate the felling of the concrete windshield which was dismantled in a piece meal small fashion with all dismantled concrete falling to ground inside the chimney for retrieval at the base.

Churchills used their in-house crane capabilities utilising Crane Appointed persons and Competent Slinger banksman to complete this phase of the job

The demolition of the concrete windshield started week commencing 15th June using Churchills specialist demolition rig and concrete cutting methodology which has been employed to demolish 2975m of reinforced concrete chimneys with wall thicknesses ranging from 150mm to 400mm

The 60m reinforced concrete chimney at the old Roche site in Welywn Garden City was reduced by 40m in only 20 days, the base 20m will be demolished using a high reach machine.

The reinforced concrete wall with an average thickness of 200mm was demolished with total efficiency using Churchills tried and test concrete cutting methodology.

Photographs depicting the chimney prior to the installation of our demolition rig are shown below.

Power Station Chimney Re Lining Project

In December 2008 Churchills were appointed directly by e-on and mobilised to site to commence with the removal and replacement of 2no 110m tall brick flues housed within a 107m tall concrete windshield.

The removal of both brick linings was completed through the Christmas holidays to ensure a hand over date of March 2009 remained achievable.

During the removal of the brick linings the internal cast concrete ring beams that supported the internal brickwork at regular intervals throughout their height were found to have eroded beyond repair. Working with e-on engineers Churchills designed replacement ring beam supports to be installed in conjunction with the re bricking of both vertical flues.

Exposed to some of the coldest temperatures in recent years and now having to work night shifts through January, February and March to remain on programme Churchills installed internal access platforms to facilitate the re building of both flues and completed on time and within budget.
