• Involves having items cast and made off site and shipped in. This is beneficial for costs, site constraints, and construction programmes.

​

• It helps costs by removing the need for formwork hire.

​

• On small sites where space is an issue, having precast is useful as the items can be delivered and installed on the day, this frees up space that would otherwise be used for formwork storage.

​

• Precast aids with construction programmes because time is saved by cutting out time which would otherwise be needed for curing – therefore there need to wait for striking of formwork is removed.

​

• Construction programmes also benefit when precast deliveries are used with a JIT system. This means the items can be delivered and installed on the same day, helping the programme to advance rapidly, rather than spending time on formwork construction, pouring, curing, and striking.
