Contract : Increase the value of the fleet

Hello,
On Matenceros Island,the science department asks me to increase the value of my park to $ 40,000,000.
He tells me that it is currently worth more or less $ 27,000,000 but I don't know where to find the information in the game. And especially what influences this value (is it the buildings, the dinosaurs, etc ...)?
Can someone help me?
Thanks in advance.
