Builders in the house please weigh in.

At the start of my project my builder billed me for 215 bags of cement. I assumed this would cover the entire project (putting up a 3 bed flat that the foundation had already been laid and adding a room to the bq already at the back of the property).

However we've gotten to the tiling and now he's saying I need to pay 250k extra for cement, sand, etc to tile the new apartment. (According to him the tiling for the bq was included in the 215 bags).

Please is this accurate or is he trying to pull a fast one here?

Thanks.
