GRAND RAPIDS (WZZM) -- It's only been open for two years but already Helen DeVos Children's Hospital is in need of expansion. When the hospital opened in January 2011 the 5th floor was left undeveloped for future use.

Monday Spectrum Health asked the state for a certificate of need that would allow for a $10 million expansion. Plans include more rooms for an increasing number of sick children. Some of the rooms may be used for intensive services, but most will be new patient rooms.

"The kids that we have are very sick kids and so when they are in the hospital they are staying a very long period of time and they're getting full quicker especially during the flu season," says Robert Meeker, Spectrum Health's strategic program manager.

As part of the project Spectrum will also be renovating the 7th and 8th floors of Butterworth Hospital. They will be used for women's services other than maternity, most likely gynecological surgeries and cancer treatments.

The plans still need to be approved by the state. Spectrum hopes to have the renovations to the DeVos Children's Hospital complete by January 2014.
