US-based HealthPartners has unveiled plans for a $140m expansion and renovation project at Park Nicollet Methodist Hospital in St Louis Park, Minnesota.

The expansion project, which is expected to be completed in 2019, will add 60,000ft² of new space and renovate 135,000ft² of existing space.

Park Nicollet Methodist Hospital senior vice-president Roxanna Gapstur said: "As the west metro continues to grow and the median age of the population increases, this project will ensure that we can meet the needs of our community for decades to come."

"The project will also include relocating and remodelling of the sterilisation or decontamination area to improve flow to and from the surgery area."

Under the expansion, two new inpatient floors will be constructed, in addition to modernising the surgery centre.

The four-year expansion project will add new fifth and sixth level floors on the east tower with private rooms, and semi-private rooms located on four to seven floors will be modified into private rooms.

The project will also include relocating and remodelling of the sterilisation or decontamination area to improve flow to and from the surgery area.

Park Nicollet Hospital is a consumer-governed and non-profit healthcare organisation that provides services, including cancer, cardiovascular, maternity care and neuro-rehabilitation medicine.

Under the Metropolitan Council, demand for hospital services is expected to increase as the number of Minnesotans who are over the age of 65 will nearly double by 2040.
