Answer is explained in the explanation section below.

Explanation:

Note: without prior knowledge of the scenario discussed here, no one can answer the question properly. But, I have found the scenario on the internet and read it carefully. Hopefully, person who posted this question must have read it too. Assuming this, I am answering this question.

Early Signs:

Actually, in this case, CityTime was cheated as the fixed price contract was shifted to material and time. As this is completely against the agreement of the contract. It is clearly mentioned in the clauses of the contract agreement as well. Furthermore, all these fraudulent changes were made without taking notice of the city time. As a consequence, actual cost of the project raised or extended from $224 million to $628 million, which is a huge loss to the company. Additionally, due to all this, project experienced several delays which further damaged the company.
