Live Environment

This project, by its nature was located on a site, which was within an occupied and operating hospital. The daily function of all occupants/users had to continue unimpeded throughout the duration of the works.
All outages and work on existing power supplies that would effect operational departments and life saving equipment had to be undertaken out of normal working hours. This called for a high level of collaboration between the key stakeholders, the clients professional team and PW.

The management and planning of the works had to consider and cater for the inherent risks of working in a live hospital environment such as:

  • Isolation procedures
  • Back up service provision
  • Work in occupied areas
  • Asbestos surveys and asbestos removal
  • Sequencing of operations
  • Installations techniques in occupied areas
  • Out of hours working
  • Emergency procedures
  • COSHH and infection risk management
