The structure of Greek buildings was generally static, stone blocks clamped blocks often clamped together with iron or wood, with iron used (though rarely) for reinforcing beams. The principle of the arch was known, but apparently the form was not admired. Brick (sun dried) was used only for minor buildings and parts of fortification walls.

The core of the pyramid, erected in layers, is made of blocks of stone blocks clamped quarried nearby, while the finer stone blocks clamped for casing the surface and the interior passages was brought across the Nile from the quarries at Moqattam and Tura (Tu-rah). The blocks used to line the sarcophagus chamber were quarried in the far south of Egypt near the First Cataract of the Nile, and were shipped down the river 700 miles.

Fragmentation is to be avoided in quarrying dimension stone blocks clamped, which is sold in blocks or slabs to specified shapes and sizes. These two distinct quarrying industries combined have a production valued at more than $1.2 billion annually, excluding abrasive stone blocks clamped, bituminous limestone blocks clamped and sandstone blocks clamped, and ground soapstone blocks clamped. The annual United States tonnage of stone blocks clamped produced or used in the mid-1960's was about 780 million. Of this tonnage, that of crushed stone blocks clamped (over 777 million tons) was nearly 400 times greater than that of dimension stone blocks clamped; but the total value of the former was only about 12 times as great. Dimension stone blocks clamped is expensive, whereas crushed stone blocks clamped brings only $1.50 a ton.
