How Early Should You Involve a Temporary Works Engineer?

Temporary works—such as scaffolding, shoring, excavation supports, crane bases, or access platforms—are essential to almost every construction project. Though these structures are not permanent parts of the building, their safety and reliability are just as critical. One miscalculation in design or timing can lead to structural instability, construction delays, or serious safety hazards.

So when should you bring in a temporary works engineer to plan and review these systems? The short answer: as early as possible. In fact, trusted professionals like NadeauSDM temporary work engineer recommend integrating temporary works planning into the very first stages of project design.

1. Why Early Involvement Is Crucial

Temporary works are not afterthoughts—they affect everything from timelines and costs to safety and buildability. Early engagement ensures:

  • Integration with the main structural design
  • Compatibility with construction sequencing
  • Identification of risks related to site conditions or logistics
  • Coordination with other temporary and permanent systems

Bringing in the engineer too late often results in rushed solutions, compromised safety, and budget overruns.

2. Pre-Construction Phase: Ideal Entry Point

The ideal time to engage a temporary works engineer is during the pre-construction or planning phase, when:

  • Project designs are being finalized
  • Construction methods and sequences are being decided
  • Risk assessments and site surveys are underway

This early input helps engineers recommend safe, cost-effective solutions that align with both structural needs and construction goals.

3. Design Coordination and Site Optimization

Temporary works often interact directly with the permanent structure. For example:

  • Propping systems must not clash with rebar layouts
  • Crane platforms must be designed with ground-bearing capacity in mind
  • Excavation support must allow for waterproofing or drainage installations

When engineers are involved early, they can optimize the design to avoid conflicts and reduce costly redesigns later.

4. Permits and Compliance Take Time

Temporary works often require:

  • Detailed engineering calculations
  • Drawings and method statements for approval
  • Permits or inspections from local authorities

Early involvement gives enough lead time to complete these processes without stalling the project. It also ensures that the systems comply with national safety standards and construction codes.

5. Improved Safety Planning

Temporary structures are among the most accident-prone components of a construction site. Early input allows the engineer to:

  • Analyze load paths, structural stability, and collapse risk
  • Specify protective measures, such as handrails or edge protection
  • Address weather or vibration impacts

This proactive approach reduces the risk of failure and enhances site safety from day one.

6. Cost Control and Efficient Procurement

Early engineering decisions affect material selection, rental durations, and installation methods. Planning ahead allows teams to:

  • Procure equipment and materials more efficiently
  • Minimize waste and overdesign
  • Optimize use of existing resources (e.g., reusable shoring or scaffolding)

This contributes to lower project costs and more predictable timelines.

7. Flexibility for Adjustments and Redesign

Construction plans frequently evolve. Early involvement gives the temporary works engineer:

  • A full picture of the project’s scope and evolution
  • Time to adjust designs as needs change
  • Flexibility to collaborate with other disciplines as challenges arise

Late-stage involvement often results in reactive solutions, which can compromise safety and efficiency.

Conclusion

Temporary works are essential for safe and successful construction—but only when planned early and executed correctly. Involving a temporary works engineer during the planning or design phase helps eliminate risks, optimize solutions, and ensure compliance with engineering and safety standards.
