C&D Consultancy, Apex Group (United Kingdom)

Project – Alltech Stamford

Client – John Paul Construction

Apex and C&D Consultancy were set a number of technical challenges in what seemed to be a relatively straight-forward demolition of a steel frame building for John Paul Construction.

Careful planning and using each other’s strengths proved critical in meeting the stringent timelines and the smooth execution of the demolition, while being mindful of environmental considerations and the small matter of preserving a US$2 million treasure chest of Japanese artefacts during the work.

Project – Kwong Wai Shiu Hospital

Client – Guan Ho Construction Co

The Kwong Wai Shiu Hospital project was especially challenging as the building is a government certified conservation site. This regulation posed a challenge to the demolition works and through careful planning, good foresight and innovative machines, the team was able to meet the owner’s needs and complete the project.

The main challenge was to demolish the internal structure of the building while retaining the façade. The presence of live buildings and nursing homes in the area also required a more controlled demolition procedure. The team thus chose not to hack the whole structure, but used cutting and crushing for structures close to the facade to minimise noise and vibration transfer

Priestly Demolition (Canada)

Project – St Michael’s Hospital Redevelopment

Client – Bondfield Construction Company (owner IO)

Priestly Demolition was contracted to perform the demolition of the existing 17 storey stair tower which was land or “building” locked within the existing functioning hospital. The only access to the work was by foot or tower crane. Priestly’s demolition plan called for the use of the on site tower crane. The obvious challenge with demolishing a stair tower is that nothing is level, so Priestly designed and fabricated a self-levelling platform to work from. This platform was installed and moved down through the floors as we went, helping us make short work of the removal.
