VA hires the best A/E firms in the country and yet we experience repeated
errors and omissions on every project. These are not new or unusual
items, but they consistently get past A/E and VA quality assurance reviews
and result in construction change orders. Please review your project
documents and make sure you do not make these mistakes.
