The vizier was the right hand person to the Pharaoh who acted in his behalf. His role was to manage projects (build pyramids and to design, engineer, and construct structures) with the right processes. The vizier advised Pharaoh on business matters to ensured the wealth of Egypt was invested and managed wisely. He managed communications with other nations as well.

Vizier Ankh-haf is considered to be the son of the Egyptian Fourth Dynasty Pharaoh Sneferu and the first known person named as vizier. He played a role in the construction of the Sphinx. His Mastaba tomb, G7510, was the largest in the eastern cemetery at Giza. A painted limestone bust of Ankhhaf discovered in his tomb is considered the work "of a master" of Ancient Egyptian art from the time of the Old Kingdom.

Hemiunu (fl. 2570 BC) is considered the architect of the Great Pyramid of Egypt. He was the son of Nefermaat, a relative of Khufu, the Old Kindom Pharaoh whose pyramid it is. Archaeologists have found references to Hemiunu with titles roughly translated as Master of works and Vizier.
The Great Pyramid of Egypt is the oldest and largest of the three Pyramids in Egypt and is the only one of the Seven Wonders of the Ancient World that survives substantially intact. It is believed the pyramid was built as a tomb for Fourth Dynasty Egyptian Pharaoh Khufu and constructed over a 20 year period concluding around 2540 BC. The Great Pyramid was the tallest man-made structure in the world for over 3,800 years.
