  1. 1. Patrick O’Keefe<br />Managing Director<br />
  2. 2. O’Keefe Group Overview<br />Company established in 1970 by Patrick O’Keefe (Senior)<br />Started out as civil ground works contractor for the major construction companies in London and Home Counties<br />Specialised in drainage and enabling works<br />Established Soil Remediation business in 1997 with fleet of specifically designed Wirtgens<br />Introduced O’Keefe Laboratory in 2002 to support stabilisation and remediation business<br />2007 O’Keefe Utilities <br />
  3. 3. Soil Remediation Technologies<br />Why did we get into Soil treatment?<br />Poor techniques in the market place<br />Low level of competition<br />Only being used on simple schemes<br />Excellent interface with traditional groundwork’s<br />The ability to introduce innovation for the better<br />
  4. 4. Soil Remediation Technologies<br />O’Keefe / Wirtgen WR 2500sk<br />Control of binder : quantity, precision and directly placed in the candidate soil <br /> Quality Control : Guarantee of engineered properties<br />Safety: binder transferred directly into machine via compressed air driven sealed silo<br /> Environmental concerns: no spread of binder due to wind/rain exposure<br /> Innovated design: First in the World<br />To date we have processed in excess of 8 million tonnes<br />
  5. 5. Soil Remediation Technologies<br />Wirtgen WR2500sk soil processor<br />
  6. 6. Lagan/Warings<br />Bournemouth International Airport<br />Sub-base replacement to apron areas<br />
  7. 7. Westfield<br />Stratford City<br />Engineered piling mat <br />Our solution prevented 125,000 m3 of material going to landfill and the importation of 80,000 m3 of stone<br />Stratford City Development<br />
  8. 8. EDF Energy<br />LudgateCellars <br />Sub-Station <br />Blackfriars EC1<br />Engineered raft removing the requirement for deep piling<br />
  9. 9. Evolution of O’Keefe Utilities Limited<br />2006 approached by EDF Energy Networks and their term contractor on the London Groundwork’s Contract to research and investigate methods to recycle trench arisings.<br />Commenced screening arisings to understand properties, volumes and potential re-use of material.<br />Trial mixes (SMR & SMF as per NRSWA 1991) developed, laid and tested for strength, frost susceptibility and general performance – on private ground.<br />2006 found leading European Mixing Plant Manufacturer and began developing and designing machines.<br />April – May 2007 live trials carried out in the following London Boroughs: Camden, City of London, Hackney, Islington & Westminster<br />September 2009 commenced five year contract with Laing O’Rourke on EDF Energy Contract. Two Sites: Silvertown E16 & Atlas Road NW10<br />
  10. 10. The O’Keefe Utilities Limited Process<br />Stabilising Materials from Arisings: Re-grading &<br />Treating for Re-use<br />
  11. 11. Reasons for introducing process<br />
  12. 12. Alternative Reinstatement Material (ARM)<br />There are different types of ARMs – we have developed a Hydraulically Bound Mixture (HBM) that isprocessed and tested in accordance with BS EN 14227 -1.<br />The material we produce is classified a Structural Material for Reinstatement (SMR) due to its compressive strength and performance capabilities and is suitable for use in the carriageways and footways.<br />The name of our recycled material is Pavimentum (PV1) which originates from the name given to the material that was used by the Romans for the construction of their roads over 2,000 years ago.<br />

  54. 54. Change in Legislation<br />In 2009 there was a major change in legislation as the <br />Highway Authorities & Utilities Committee (HAUC) <br />identified the demand for recycled materials was <br />increasing due to the European Waste Directive, <br />increasing Landfill and Aggregate Taxes and Utility <br />Companies environmental policies.<br />(EDF Energy introduced a Zero Waste policy in January 2008)<br />
  55. 55. HAUC Advice Note<br />HAUC Advice Note 2009/01 was provided specifically for the use <br />of Alternative Reinstatement Materials within reinstatements <br />for utility excavations.<br />The above document was issued with the following recommendations:<br />Hydraulically Bound Mixtures:<br />HBMs manufactured and used in accordance with detailed requirements given <br />in the Specification for Highways Work 800 Series may be considered for <br />national use. HBM’s may be used without the need for a trial with individual <br />highway authorities in accordance with Appendix A9 of the Specification.<br />
  56. 56. Local Highway Authority Open Day<br />To ensure good working relationships in conjunction with our Partners, we <br />met each of the London Highway Authorities to explain the process, PV1 <br />performance criteria, the quality management and testing regime.<br />Additionally we held an open <br />day at our Silvertown<br />SMARTR deport in October <br />2009 to give the Authority<br />Representatives first hand <br />experience of the process and <br />material. <br />We continue to share <br />Information and send the<br />monthly test summary <br />reports.<br />
