2 SOIL AND ROCK SAMPLE ANALYSIS LABORATORY TEST REPORT To: Bord Gais Copy: Orla Smyth From: Stephen Watson Laboratory Manager Causeway Geotech Ltd Tel: +44(0) Date: 25/02/15 Ref: Greater Dublin Drainage Scheme Ground Investigation We are pleased to attach the results of laboratory testing carried out for the above project. This memo and its attachments constitute a report of the results of tests as detailed in the Contents page(s). The samples were delivered to our laboratory in Ballymoney, Co. Antrim on 18/01/2015 and tested in accordance with the electronic schedule received on 20/01/2015. Further testing instructions were received on 16/02/2015 All testing was performed 26/01/2015 to 25/02/2015. The attached results complete the testing requested and we would therefore wish to confirm that samples will be retained without charge for a period of one month from the above date after which they will be appropriately disposed of unless we receive written instructions to the contrary prior to that date. We trust our report meets with your approval but if you have any queries or require additional information, please do not hesitate to contact the undersigned. Approved Signatory Stephen Watson Laboratory Manager
