Spanish Engineering and Construction TermsThe contents of this document are derived from a Spanish/English glossary started during the course of one of our past projects. Although it has undergone an initial review for content and spelling, this document is to be considered a preliminary draft and most likely will need additional fine-tuning as it is reviewed and employed by others. It was decided that it would be better to have the glossary in the hands of users to start employing it in our work and through that effort, uncover any additional corrections or additions deemed appropriate. We believe that a document such as this, technical in nature and available through our Intranet, will be very useful in our work. Any corrections, additions, comments and/or suggestions may be forwarded to Scott Heffley, Mechanical Engineering +1 949-349-4049.
