Riyadh metro station night pour: how to schedule pumps and crews?
Faisal A.

The Riyadh metro station is entering its main pour. Site temperature approaches 45°C by day, and the engineer only allows night pours.
One 56 m pump covers two work faces, but there are only two vibration crews, and night access is restricted by traffic rules.
How should pumps and crews be balanced, and how should curing and test cubes follow the night shift?

Size the pump by hourly output, not by the number of faces; with a short night window, a spare pump beats an extra one.

Tie the batching plant, transport and site permits into one night plan; material breaks are more common than equipment failure.

Take test cubes by pour batch, not by day or night shift; record placing temperature and covering time.
