ARRANGING PRECAST PRODUCTION SCHEDULES USING

PRECAST PRODUCTION PROCESS Precast fabrication can be divided into six steps, i.e. mold assembly, placement of reinforcement and all embedded parts, concrete casting, curing, mold stripping, and product finishing (Ko 2010), as shown in Figure 1. Different with production systems, precast elements are produced stationary instead of conveying by belts due to their

leaN PRODUCTION IN The PReCaST CONCReTe COmPONeNTS’

Just-In-Time (JIT):this is a production method based on “Pull”, where each step demands from its previous step. This is in opposition to “Push” production, where each step pushes its finished product on to the next step. Jit strives to deliver the right product at the right time in the right quantity.

Precast concrete - Wikipedia

Prestressing is a technique of introducing stresses into a structural member during fabrication and/or construction to improve its strength and performance. This technique is often employed in concrete beams, columns, spandrels, single and double tees, wall panels, segmental bridge units, bulb-tee girders, I-beam girders, and others.
