    VALE TODD WIEDEMEIER (2.6.1964 - 13.7.2017)

    All of us at ACLCA NSW are extremely shocked and saddened to hear of the recent death of Todd Wiedemeier. Todd was a world renowned expert in the field of MNA and had travelled to Australia on numerous occasions to run MNA short courses for various ACLCA chapters.  He was an extremely intelligent man with a love of life and a great sense of humour.  We would like to extend our heartfelt condolences to his family and friends from all of us here at ACLCA NSW.


    ACLCA NSW member company, C.M. Jewell and Associates Pty Ltd, has recently been engaged by the NSW EPA to review and revise the Guidelines for the Assessment and Management of Sites Impacted by Hazardous Ground Gases, originally issued in 2012.

    The review and revision have two main objectives:

    • To maintain consistency with Australian and overseas publications referenced in the guidelines that have been updated since the guidelines were originally issued (for example BS 8485), incorporate new reference material where relevant, and update the data tables where necessary; and

     • To incorporate practical experience gained by Australian consultants and public authorities in the five years since the original guidelines were issued.

    Some housekeeping issues such as broken links will also be addressed.

    Any contributions on the revision would be appreciated, particularly with regard to practical experience in the assessment and management of ground gas in NSW or Australia more generally.  Any such contribution will of course be acknowledged in the revised guidelines.

    Please reply directly to [email protected] with any contributions or suggestions.
