MemorialCare unveiled a true-to-size mock-up Wednesday of a new 80,000-square-foot building that will soon house all of its pediatric services under one roof.

The public got a chance to tour the cardboard mock-up inside a giant white tent on the campus of Miller Children’s & Women’s Hospital Long Beach, near Spring Street and Long Beach Boulevard.

The new building, expected to be complete in 2021, will include four stories with exam rooms, an imaging department and an education center, hospital officials said.
