  1. Richard Doll Building for Oxford University

  2. Movement for innovation Demonstration project:– Richard Doll Building, University of Oxford Project team • Client University of Oxford • Architect Nicholas Hare Architect • Structure & Services White Young Green • Quantity Surveyor Turner & Townsend • Main Contractor HBG Construction South East

  3. Project details • New facility for Trials & Epidemiology department who will move from the John Radcliffe Infirmary • 7,300m2 • £10.5 million contract sum • Two-stage procurement • Traditional JCT 98 • Currently on-site with demolition start new works 3 March 2003

  4. Waste cycle Innovation to be demonstrated ‘Commitment from an integrated project team to consider waste minimisation and sustainability from the outset through design, specification during procurement and on site’. Design Procurement Construction

  5. Why implement the innovation • Construction is a high generator of waste • Frustration with current waste levels How can the average projects respond? • Realise financial benefits • Realise safety benefits

  6. Focus of demonstration team 1.0 Design [Andrew Mulroy] 2.0 Procurement [Anthony Nagle] 3.0 Construction [Anthony Nagle] 4.0 Measurements [Duncan Goodall] Design Procurement Construction

  7. Design • Finishing trades identified as major source of waste by HBG • Internal finishes reviewed generally with respect to waste • Staircase wall finishes changed from dry-lining to fair-faced concrete • Exposed recessed joints set out to allow adoption of standard formwork

  8. Design • Insulation of roof upstands • Concrete profiles amended to accommodate standard boards • Design note added to specification to communicate to contractor how boards are to be cut to minimise wastage • 711 Insulation to upstands: • Manufacture and reference: Dow Construction Products, Roofmate LG-X or equal approved • Material: extruded polystyrene, CFC and HCFC free • Thickness: 100mm plus 10mm cementitious face • Do not lay insulation until roof is clear of other subtrades. • Clean off all dirt and debris from base • The roof build-up has been designed so that perimeter upstand insulation is always 400mm high, allowing standard boards to be cut into equal thirds to eliminate wastage. Set out to minimise cutting and avoid small cut pieces at perimeter and penetrations. • Insulation boards to be adhered to asphalt-finished up stands as recommended by installer • On completion of laying ensure that boards are in good condition, with no springing, flexing or rocking. Secure boards against wind uplift as soon as practicable

  9. Design • Desired profiles drawn • Relationship of insulation to window investigated • Relationship optimised to use standard insulation boards and minimum aluminium profiles through coordination with relevant contractors

  10. Price  Safety  Quality  Programme  Sustainability  Procurement Agenda Specification Selection process Weekly site meetings Pre-start meetings Subcontractors orders Design Procurement Construction

  11. Procurement Examples achieved • Displacement piling • Optimise formwork setting-out to maximise re-use and minimise waste • Sto-render selection of product • No timber pallets policy Design Procurement Construction

  12. Construction Waste management

  13. Construction Target areas • Timber • Packaging • Insulation • Plasterboard Design Procurement Construction

  16. Measurement What and how What • Total volume of waste in cubic metres • Percentage recycled • Capital cost savings achieved • Feedback on waste generating trades and BRE How • Use of wheelie bins / skips known volumes • Record of each bin / skip contents and volume • Effects of client variation on waste • Effects of design change on waste Design Procurement Construction

  17. Measurement KPI BRE range HBG GreenPark range 2.5 5 10 15 20 25 30 35 Richard Doll Building target range Values denote m3 / 100m2 Chart taken from: BRE environmental performance indicator: office waste Design Procurement Construction

  18. Summary The innovation: why implement? • Reduce waste, increase productivity and assume responsibility
