Follow each cast element from drawing mark to mould, curing, yard bay and crane.

Every precast element has a mark, such as B-214 or WP-07, and the mark is the only name the site knows it by. If the mark, the revision or the cast date is wrong, a heavy unit arrives that cannot be placed. That is costly.

Production tracking for precast plants follows each mark through the casting schedule. Rebar, embedded plates and lifting inserts are checked before the pour, and demoulding strength is recorded before the unit moves, so the crane never lifts on a guess. The erection sequence drives what loads first.

The planner takes an element schedule from the project drawings and assigns marks to casting beds and moulds for the week, allowing for mould changeovers and the dates the site asked for. The steel shop cuts and bends bars into cages, and the fixing team places embeds, sleeves and lifting anchors. The supervisor checks cover and positions against the shop drawing before the concrete is poured. Nothing is poured unchecked.

Cubes are cast with each pour. They cure beside the unit. Once the cube result reaches the strength set for lifting, the unit is demoulded and a crane places it in the yard. It may wait for steam or water curing, finishing touch-ups or a coat. Trailers are loaded in erection order. The mark list is signed at the gate.
