When attaching MAS™ structures to one another in a retro-fit scenario the door way is made by extending the 4 foot window opening to the slab. When attaching MAS structures to one another DURING construction there may be other options. Such options must be engineered and may include eliminating the majority of this single corner connecting wall in both units such that the connection is “seamless”. Such engineering is provided by MAS™ at no additional cost as part of the ADELS Fee.
Unlike conventional construction, the cost to add an additional MAS™ structure is virtually the same whether it is done during initial construction or via a retrofit (remodel) at some later date.
Note: In the retro-fit scenario the extension of the 4 foot window to the slab to create a doorway is done as follows:
- Removal of the window unit if installed
- Saw cutting the concrete to the floor following the vertical lines of the window edge opening
- Saw cutting and chiseling between these saw cut vertical lines and the slab
- Removal of the concrete panel below the window
- Shotcreting the saw cut and chiseled edges when the new MAS™ structure is constructed so as to encapsulate and protect any re-bar exposed during the cutting process and to finish the opening to the required width/height. (Additional re-bar and doweling may be required if more than a few inches of Shotcrete is required to make the opening narrower or shorter)
