ABSTRACT
The dry masonry structure of Segovia Aaqueduct (ca 100 AD), in granite, is a masterpiece of Roman construction design. Observation of hoisting holes and scaffold holes are analyzed on their impacts. Photographs show the existence and position of the holes. Since the brittle material reduces detailing options, only traces of simple holes have survived over time. Hypotheses on the origin of these holes are discussed, also by comparing aspects to other insights on Roman scaffolds. A possible light scaffolding system is presented for the aqueduct’s piers. They were mainly work platforms, not to be used for storing granite blocks. Possibilities of safe wedging of the blocks at high altitude, necessary because of the hoisting device iron forceps, are presented, also in respect to ergonomics. In drawings, phases of the construction process and its careful preparation by skilled staff are illustrated. The current contribution adds substantial new insights.
