They can save you money, reduce the risk of cost escalation, and are often provided pro-bono by a good contractor. When it comes to requesting a contractor's constructability review, timing is important. If the review is performed too late, problems could result, including confusion surrounding the project, loss of significant time and money, and hefty change orders later in the project. The question then is: when is the optimal time to have a contractor perform a constructability review?

An important duty of FERC is to monitor conditions of the more than 1,700 non-federal, electricity-generating dams in the US. They also set [standards](https://www.ferc.gov/industries-data/hydropower) that hydropower project owners must follow to ensure the safety of the general public. This includes mandating regular inspections of hydropower projects to certify they are in sound condition and comply with the Commission’s safety standards. Owners not in compliance with the Commission’s inspection standards risk losing their power generating license.
