The advantages of plano-convex bricks were the speed of manufacture as well as the irregular surface which held the finishing plaster coat better than a smooth surface from other brick types. Bricks were sun baked to harden them. These types of bricks are much less durable than oven-baked ones so buildings eventually deteriorated.

Advances in technology such as 3D Printing, drones and robotics, GPS, building information modelling and pre-fabrication increased the efficiency of construction. The United States was the first adopter of 3D printing technology in construction where huge machines would "print-out" cement in layers to form the walls of buildings. [27]
When scientists recently examined bricks dating from the third to the first millennia BC in Mesopotamia — which encompassed present-day Iraq and parts of what is now Syria, Iran and Turkey ...

Other examples of mud-brick buildings that also seemed to employ the "true" dome technique have been excavated at Tell Arpachiyah, a Mesopotamian site of the Halaf (c. 6100 to 5400 BC) and Ubaid (c. 5300 to 4000 BC) cultures. [19] Excavations at Tell al-Rimah have revealed pitched-brick domical vaults from about 2000 BC. [20]
Ubaid culture is characterized by large unwalled village settlements, multi-roomed rectangular mud-brick houses and the appearance of the first temples of public architecture in Mesopotamia, with a growth of a two-tier settlement hierarchy of centralized large sites of more than ten hectares surrounded by smaller village sites of less than one ...
The creation of smaller bricks enabled the creation of decorative niches and projections which were to be a characteristic feature of Mesopotamian architecture thereafter. The layout of the buildings was also novel, since they did not continue the tripartite plan inherited from the Ubayd period: buildings on the Eanna at this time had ...
