Preliminaries

Also known as: Prelims

Preliminaries, or prelims, are the project-wide costs of running a construction site that are not tied to any single item of work.

Preliminaries, usually shortened to prelims, are the costs of running a construction project as a whole rather than the cost of any specific trade or material. They include things like site management, welfare facilities, scaffolding, temporary services, insurance and plant hire.

Prelims can be a significant share of a project’s cost, so estimating and tracking them accurately is important to protecting margin. Sync’s cost tracking keeps budgeted against actual spend in one view, prelims included.
