The Design Tool for Civil Engineering projects – an overview

1. The Design Tool for Civil Engineering projects – an overview Phil Birch & Susan Steensma Cyril Sweett 22-09-10

2. Aim of training session • Discuss the background to the ‘Designing out Waste’ (DoW) process; • Explain the role of the tool in helping DoW; • Demonstrate how to use the DoW Tool for Civil Engineering projects (DoWT-CE).

3. Agenda • Introduction • What is ‘Designing out Waste (DoW)?’ • Summary of the tool • Example inputs and outputs • User guidance • Design guidance for Civil Engineering projects • The tool in use • Q + A

4. What do you want to achieve today?

5. What is ‘Designing out Waste’ and why is it important?

6. Background

7. Objectives • Benefits of designing out waste • Principles of designing out waste • Designing out waste process • Design guidance and tools

8. Why take action? • Materials resource efficiency • Landfill tax • Site waste management plans • Environmental assessment • Client benefits

9. Waste Hierarchy

10. The role of Designing out Waste in the overall design and construction process

11. Supply chain interfaces • Pre-construction Tendering & appointment Model wording • Outline design Prevent waste SWMP Template Designing out waste tools/guidance • Detailed design Forecast waste Reduce waste Increase RC Net Waste Tool • Construction Waste reduction Waste recovery Measure performance • Post-construction Review performance Benchmarking SWMP Tracker Reporting Portal

12. The principles of ‘Designing out Waste’

13. Principles of Designing out Waste Design for: • Reuse and recovery • Off site construction • Material optimisation • Waste efficient procurement • Deconstruction & flexibility

14. Design guidance for civil engineering projects • The design solutions provided within the tool are in-line with the recommendations in the Design guide • Use the guide to evaluate options

15. The Designing out Waste Tool for Civil Engineering projects (DoWT-CE)

16. DoWT-CE

17. Design tool Produce an indicative waste forecast Design review workshop Decide on actions to reduce waste through design Design tool Enter actions and calculate impacts SWMP Record indicative waste forecast and waste prevention actions Designing out waste process

18. Example – Headline results • The engineer used the DoWT-CE to: • Identify opportunities to Design out Waste • understand the cost of waste • set actions to reduce waste arisings • increase the recovery of waste

19. Explanation of data hierarchy Element – A fundamental aspect of civil engineering i.e. earthworks/drainage/etc Sub Element – An aspect of an element i.e. a type of drainage option Component – Sub elements comprise of a number of components. For example drainage options would consist of pipe, bedding, top soil etc (all of which are components)
