Click on the link below to see an NRG building in a CADBLOX format.
From the CADBLOX.com website:
"CAD BLOX exists to assist in the ordering and installation of architectural masonry products. We’re here to reduce the time, cost, and frustration involved in ordering and building complicated masonry jobs. We can help you understand the products, order them accurately, resolve design issues related to CMU, layout bond patterns, stage complex orders and increase your productivity in the field with color coded 3D layout drawings. If you order or install masonry products, we can help. If you need a detailed model of your masonry installation to satisfy BIM requirements, we can provide that as well."
Mike Giem at CADBLOX is a pleasure to work with, and the finished product speaks for itself.
Flashing: using the above NRG detail drawings link, see pages 18-30.
Like all single wythe walls, proper flashing is key. BlockFlash http://www.aecinfo.com/1/company/ 08/70/61/product312085_1.html and traditional step flashing have both been used with success in NRG projects.
