The survey and analysis will enable Duke to comply with the Facility Ratings Methodology Level 2 Alert issued by the North American Electric Reliability Corp (NERC) in October 2010.

Under the contract, Burns&McDonnell will obtain aerial surveys of all transmission facilities and utilize the data to develop computerized models of each line with an accurate representation of survey conditions.

The models will be used to perform a thermal rating assessment for each line at both NERC and Duke clearance requirements and to develop a summary of results showing any areas of non-compliance.

Burns&McDonnell is a provider of engineering, architecture, construction, environmental and consulting services.
