Overview
Keep up to date with global best practice for designing temporary working platforms for cranes and piling operations.

Temporary working platforms for cranes and piling rigs are high-risk for those using them as well as those designing them. Many elements must be considered during design and construction phases.

Appropriate load input parameters need to be carefully selected to obtain the correct load cases. And robust and reliable design methods (including geotechnical parameters selection) need to be applied to assess the required thickness and stiffness of the working platform. 

This course shares industry best practice methods for design and verification, covering both theory and practical application.

You’ll learn about:

  • the FPS  method to assess the critical track pressures applied by piling rigs;
  • two common guidelines for the design of temporary working platforms (BRE470 and TFW2019);
  • the applicability of the different design methods for various ground conditions; 
  • the underlying design assumptions about load transfer from piling rigs and cranes; as well as 
  • the consideration of static and/or dynamic load factors in the different design approaches are briefly introduced. 

Course facilitator and civil engineer with over 20 years’ international experience, Dr Martin Larisch will also discuss the most suitable soil investigation techniques to use for subsurface investigation works and the potential verification methods for platform verification/ certification. 

To demonstrate the practical application of these concepts, the course will also include will include real world examples to expose some of the limitations and related risks.

  • Geotechnical engineers
  • Civil engineers
  • Structural engineers
  • Temporary works designers
  • Site managers
  • Project engineers
  • Project managers
  • Construction managers; and
  • Professionals from piling and crane companies
Prerequisites

Participants should be familiar with fundamental geotechnical and structural design principles but no experience in working platform design and assessment is required.

Topics we'll cover

Topics we'll cover

  • Conceptual load assessment and bearing pressure assessment based on different load cases (FPS method), 
  • Basic ground investigation methods for the design of working platforms and fundamental assessment of geotechnical design parameters 
  • Introduction of the two common design methods for the design of temporary working platforms (BRE470 and TWf 2019 methods) 
  • Comparison of the methods, their potential outcomes, limitations and risks of the methods and discussions about the consequences for construction projects 
  • Introduction of some selected verification methods for working platforms ranging from complex (e.g. geophysical methods) to simple methods (e.g. proof rolling) depending on the project risk, plant loading, ground conditions and application 
  • Practical examples and calculations of the track bearing pressures for bored piling, CFA and driven piling rigs, and crawler cranes. 
  • Calculation of working platforms under different plant loadings and different subgrade conditions (e.g. cohesive soils, granular soils, changing groundwater levels)

How you'll learn

The course will be delivered in two x two-hour sessions.

Session one

The first session will cover theoretical and general background information about load input from piling rigs or cranes, basic design methods and platform verification.

Session two

The second session will focus on practical application of the content covered in session one, including real world examples (with calculations) and group discussions.

Delivery platform - Zoom

These sessions run through Zoom. On the day of the webinar you will receive the unique Zoom link at least one hour before the webinar is scheduled to begin.

We suggest that you download the Zoom Desktop Client to ensure you can fully participate in the webinar. If you view the webinar through the Zoom web browser or via a phone or tablet device you may not be able to participate in the interactive elements such as answering polling questions.
