For the builder in buildcraft 3 - see this.
The Builder was disabled from version 3.4.2 until Beta Release 6.0.8 due to major bugs.
A builder is a machine that, when powered, will automatically build a structure based off a template, using resources supplied by the player. As a note, the template does not include the types of blocks in the original template, so that it will use whatever you put in the builder, and not in any pattern. If, however, a blueprint is used in place of a template, the types of blocks are recorded. Once placed, a stone pick or greater is required to retrieve the builder.

Place the builder in your world, and right click on it to display the builder interface. Place a template into the template slot.The area that the template uses will be displayed in the world so you can adjust the position of the builder if needed.
Put some resources into the builder, and supply some power, and the builder will automatically build the structure from the template. A steam engine or greater can power a Builder. 2 green status combustion engines burning fuel are required to fully power the builder.
At this power level, the builder will place approximately 350 blocks a minute, or 5 and a half full stacks. If there is something in the area already, the builder will either remove it if it is not part of the template, or leave it there if it is. Blocks removed this way will remain on the ground, they will not pop out of the builder.
