Acting chief executive Karena Prevett said PDH would like to apologise in advance for any inconvenience and to ask people to be patient during the construction phase.

"The main transportation lift near the main entrance is 30 years old and needed replacement," Ms Prevett said. "It's good news but it's going to be a bit of an inconvenience for a while."

PDH received $400,000 for the project from the Department of Health.

There will be alterations to traffic flow and signage to direct people to the service lift if needed.

"The flow and signage will be under constant review during the lift replacement period and during peak times there will be assistance with foot traffic management," Ms Prevett said.

"We're encouraging people to use the stairs as much as they are able, but we do have the service lift if needed and it's not too far to walk," she said.

"If the lift is required, please be patient as there will be a high demand."

Works to install the new lift near the main entrance will start on Wednesday October 21 and are expected to finish in early December.

During construction, visitors and staff are being encouraged to use the stairs, however, people needing to access the upper levels will have access to the service lift.

During the construction, the main entrance to PDH will remain open and health screening will still occur, as directed by DHHS.

All contractors will be COVID tested prior to starting work on site.

Ms Prevett added that all services would continue in their usual locations during the construction.
