On 10 November 2009, Cabinet gave consent to authorise officers to undertake a procurement exercise for a contractor to demolish Kipling Tower. This was required because the contract value was expected to exceed £1million.
A competitive procurement process was carried out in accordance with Ealing Council’s Contract Procedure Regulations, and after thorough inspection of our proposed methodology, quotations and proposed working procedures, Cabinet requested to award a contract to DDS Demolition.
The contractors shortlisted to be invited to tender were pre-selected via the Local Authority Constructionline system based on their feedback scores and turnover. The procurement process and pre-contract work was supported by a specialist demolition consultant to ensure that an appropriate demolition contractor was selected to deliver this task.

- Due to numerous mechanical difficulties with hired equipment, DDS fell behind schedule early on in the contract. However DDS still managed to complete the contract on time by hiring in another High Reach, at no additional cost to the client
- Demolition was carried out close to site boundaries; with a building site 6 metres away and a live road 5 meters away. Demolition was carried out at no risk to the public and building contractors thanks to an intensive traffic management solution, and constant liaison with the neighbouring site.
- The 12 storey building presented logistical difficulties with arisings from soft stripping works on upper floors. DDS utilized the disused lift shafts in the building to quickly and safely transport materials to ground level.
- Despite the potential for high levels of Dust Contamination, DDS managed to control the environment and received no complaints from the public.
- Kipling Tower had a complex structure which required intensive front end engineering planning and liaisons with external specialist consultants.
