There are rules stipulating that contracts can't be split to avoid certain thresholds when requirements are in place.
It's hard to say whether that's normal. If the three contracts were very different and very separate, if they were for very different services and they weren't connected, it's possible. However, there are a lot of rules around contract splitting. It's important to ensure that processes are followed so that contracts aren't split.
I'm not sure whether that answer is helpful.
