It is always a pleasure to see what people went through to become specifiers. Dennis Hall once wrote a great article a few years back about what it takes to be a specifier. Basically it can be any number of variations of the stories that appear in this thread.
To become a good specifier, you must know how to communicate. That is what we do. Becoming certified via CDT, CCS, and CCCA shows the industry that you have learned how to speak the language. Take at least a couple of classes on reading construction drawings. That will be one of the most important ways that architects will be communicating with you. You’ll know that you’ve reached a milestone when you can look at a detail and make it better.
Become detail-oriented. That’s another key aspect to our function. We’re here to make sure that every aspect of the project has been addressed in a meaningful manner.
Unlike many of us, internalize the 4 C’s - Clear, complete, concise, and correct. It’s easy for each of us to go on about this forever; we’re passionate about it.
Personally, I was a physical sciences major who went to work for my father because he had to fire 3 spec writers in a month; they weren’t focused on the details. I started out measuring buildings and drawing up floor plans. After a few months I was able to sit in on planning meetings with the hospital staff where I learned about programming space. Then I learned how to put a set of drawings together. Finally came my chance to feel like a complete idiot, writing my first spec. That was 1976 and I’m learning more now than I was able to learn then.
I’m not a registered architect, just a CCS and CCCA. Oh, I do teach Construction Specifications at the local community college (maybe a good place for you to look into classes on spec writing and drawings) and I’m involved in teaching the certification prep classes every year with other members of our profession. That’s the best way for me to learn.
Robin, I hope your brother-in-law finds his niche. I look forward to welcoming him into our little community.
