Ajay,
As long as the courses and training are relevant to your engineering career, I agree that they should be added to your resume. I would be very selective of adding webinars to your resume, as continuing education is typically a requirement for most engineering careers. I would not use valuable resume space on webinars unless they were on a unique topic that many people do not have experience on, or that are specific to the job you are applying for.
I have a section on my resume called Related Skills, where I list my certifications, completed training courses, and software classes. This section could also be named Training, if you have at least 3 or 4 different training courses or classes completed that are related to engineering.
I would list this section under your Objective, Education, and Work Experience sections of your resume.
I hope that helps. Also, ASCE is currently holding a Resume Workshop, so if you are interested in submitting your resume to be reviewed, you can do so here:
