Preliminary & General (P&G) in Construction

Writer: Steve ChangSteve Chang

Builders often ask why the Preliminary & General (P&G) section is included in our estimates. It’s common for builders to overlook these costs, only to later wonder why their projects aren’t as profitable as expected.


What is P&G?

P&G represents essential indirect expenses required to manage a construction project efficiently. While these costs may not be immediately visible on-site, they are crucial for smooth operations.


Examples of P&G Costs:

  • Insurances

  • Signage

  • Temporary Hire Items (site toilet, site shed, rubbish bins, site fences)

  • Temporary Utilities (Water & Electricity)

  • Project Management & Administration

  • Health & Safety Provisions

  • Consumables and Small Plant Recovery

  • Freight - equipments and materials

  • Travel & Vehicle expenses


Why Charging for P&G is Essential?


  • Covers hidden costs

    Many P&G items—such as permits, insurance, site security, and administrative expenses—aren’t visible on-site but are fundamental for project execution.


  • Ensures project viability

    Factoring P&G costs into the budget helps contractors estimate expenses accurately and avoid financial losses due to overlooked costs.


  • Professionalism and transparency

    Clearly listing P&G charges in quotes assures clients that all project aspects have been considered and priced fairly..


  • Risk mitigation

    Properly managing P&G expenses helps prevent budget overruns and potential disputes by ensuring all necessary costs are accounted for from the start.
