Hi,
I have a pretty hazy memory of it (~14 years does that. 
), but I think those fall under the ‘overlay’ category, the same method by which ore got placed.
I can’t remember if support for that ever made it into RACK. If it didn’t, I’d imagine the intention was to use the editor built into Red Alert itself (the one which uses their game engine) to place sandbags, walls, and ore.
Thanks.

Mr. Pugh
I need some help with the Red Alert Construction Kit. Specifically I need to know if a version exists that allows the user to place barriers such as sandbag and concrete walls.
