1. A system for construction, the system comprising:
a plurality of guide rails positioned proximal to a receiving surface and in substantially parallel alignment and direction to one another, at least one of the guide rails having a spaced region forwardly offset from the receiving surface such that the spaced region of said at least one guide rail is placed in front of the receiving surface and application of a construction material against the receiving surface behind the spaced region is not prevented or contained therein by said at least one guide rail; and
a screed configured to simultaneously traverse along at least a selected portion of at least two of the guide rails, the screed having a protruding region such that as the screed is traversed along at least said selected portion following application of the construction material against the receiving surface, the protruding region is operative to rod the construction material so as to impart a contour to the construction material at least partially defined by the selected portion of the at least two guide rails;
wherein the at least two guide rails are configured such that the contour imparted to the construction material is substantially dissimilar from that of the receiving surface along a direction thereof.
