ADVICE: Allow reasonable time for processing specs, measured beginning when you provide reasonably clear design input and updates for specs. In case you are not sure what input is needed for specs - if it is about quality or type of materials and systems, it should go in the specs. If it about location and extents it should go on the drawings using only very generalized terminology that ties it to a spec section or subheading in the specs. In case you are not sure what is reasonably clear input - if it is an all products catalog from a manufacturer, that is not helpful - you could just as well have said please add mfr x to the list. We do not know what product or application you are talking about. Help us understand its function and how it is being used, what performance and other salient attributes you care about. If it is a cut sheet with various options please mark them. Review it and clean it up before you send to your spec writer if it is something you would reject if received in a construction-phase submittal because it is not clear which products they are proposing or what applications. Collect these cut sheets as you are designing, and mark them with the products you chose.
WHY #1: IT IS YOUR JOB TO GIVE THE SPECIFIER GOOD INFORMATION FOR WHAT ARE ACTUALLY YOUR* SPECS. However, some people seem to believe that if you have a spec writer you never even have to look at the specs. Quite the contrary per the AIA and statutes. The Specifications right along with the Drawings are YOUR* instruments of service to the Owner. See AIA B101 Standard Form of Agreement Between Owner and Architect (which also applies to subconsultants under pass-through provisions). It does not become someone else’s responsibility because of it being on 8-1/2 by 11 sheets. According to AIA and statutes, the Designers of Record own the responsibility for the specs and the drawings alike. A spec writer unless he/she is also the Designer of Record has to work under the direction of the Architect or other DOR – we operate much like a draftsperson who is not licensed, and even if we are a licensed design professional, we still are not the DOR for your project. If we do not receive good direction, we just have to go with whatever direction if any that we receive.
So even if your title does not say you are a designer + specifier simply because no one waved that magic wand over you yet, you are a specifier in the sense that the B101 says you are - the specs are part of YOUR* instruments of service. For collecting the input for specs, it is always easier to do it now while it is at your fingertips than to ever hope to recreate it later.
WHY #2: BECAUSE IT WILL SAVE YOU TIME. Yes that is right, SAVES YOU time overall. If you gave your specifier good quality information in plenty of time: A. During design you will find it much easier to mark up those specifications because the first draft can be oh so much better, & B. Your spec writer can give you more value in YOUR* specifications that you will use to administer the construction contract.
If you keep it in your consciousness about what info will be needed for YOUR* specifications all the while that you are collecting information for your drawings, you are helping yourself as well as your specifier, and you will thank yourself when you can look back at your marked cut sheets during bidding and VE – why did we use that product… oh yes, that is why! How does the VE product compare – hmmmm, where is the value in this “VE”? Why, this product they are proposing is not even recommended by the manufacturer for our application!.. or hmmmm, their product is 4 times thinner, it can’t be just as durable no matter that their tests of other attributes sound good - and they keep pushing the issue so lets see how the Owner feels about “saving” money with this suggestion.
And you will thank yourself again during construction as all the submittals come in. You will have something extremely useful that you can immediately compare them against.
WHY #3: IT MAXIMIZES THE VALUE THAT THE OWNER RECEIVES IN THE END PRODUCT OF THEIR BUILDING when specs are clear and consistent, allowing bidders to accurately price and reasonably compete. Informed owners will recognize the difference between useful and messed up specs and be more likely to keep coming back to your firm for their services.
