I'm just wondering if anyone is using GBCI's Better Materials site as their go-to source for transparency and healthy materials.  Having all the search engines on one platform is great in theory, and I keep hoping that it will be the one-stop site/resource that I can get all our designers to use.  Unless I'm missing something though, it still...

To piggyback off Nathan's introduction where he mentions construction waste management, who is doing anything innovative or different in managing construction waste?  Construction waste has not historically been a passion of mine, but now working in sustainability and construction, I feel like it has to be by default.

Hey gang,

We're working on a project that's currently designed as mass timber. We're up against some cost control efforts (of course) and the CM/Client is asking about changing some of the building to steel or green steel.
