Buildipedia

"Buildipedia was created by AEC professionals to fill their unmet need for a site to share knowledge, promote best practices, and advance their understanding of building processes.
Since its public launch in 2010, Buildipedia has established itself as an invaluable resource for the home improvement and DIY crowd, in addition to the professionals who frequent Buildipedia looking for the latest in design and construction. 

With new videos, articles, and photo galleries coming every week, Buildipedia is poised for explosive growth as an increasing audience of professionals, students, and consumers go online seeking answers, solutions, and the right products. 

Buildipedia's operations, including editorial, marketing, sales, web & video production, are based in Columbus, Ohio."
