The use of extended stigmergy which is the augmentation of the basic notion to stigmergy by increasing the capabilities of environmental elements, is illustrated. Swarm systems, the most impressive examples of construction in nature, are especially suited as an approach for artificial construction systems. A swarm of autonomous robots can be programmed to build arbitrary structures and extended stigmergy can improve construction time while increasing the opportunity to exploit parallelism. Human construction projects use rigid materials and involve regular shapes with right angles. The benefits of the extended stigmergy can include increased robustness and faster completion of a desired structure.
