If you have previously had a predominate use study rejected, contact us for a no-obligation consultation. The rejection may have been based on any one or more of these reasons: non-qualified business model, improper format, inaccurate/incomplete content, not balanced with the usage history, not certified by an engineer from an accredited college of engineering. It is also possible that the predominant use study was done correctly; but nobody was there or trained to defend the study. If National Utility Solutions performed your study, contact us since we also handle the defense of our predominant use studies at no additional cost and will honor our guarantee that our study is valid per the various State regulations if we are given the opportunity to defend said study.
