CSA S250-11 and CI/ASCE 38-02 - How to Effectively Utilize These Utility Standards for Shale Energy Projects

摘要

Published in September 2011, the CSA S250 - Mapping Underground Utility Infrastructure will play a key role in the creation of more accurate and reliable as-built utility drawings and maps. CI/ASCE 38-02 - Standard Guidelines for the Collection and Depiction of Existing Subsurface Utility Data, which was published in 2003, has already been used extensively on infrastructure projects across Canada and the US. Together these two standards form a solid foundation to both map and records utility infrastructures. The location of existing utilities can play a key role in the design and implementation of infrastructure projects associated with Shale Oil & Gas production. These impacts need to be managed properly to avoid significant cost and schedule over runs. CI/ASCE 38-02 forms the basis for engineers to create accurate drawings of existing conditions for the project. The data proved upfront is a critical, however equally important is the generation of accurate, reliable maps and drawings of new utility infrastructure placed in the ground. Creation of these new records is the primary focus of the CSA S250 Standard. The paper will review the key highlights of the new CSA S250 standard including - standard symbology, Accuracy Levels, and data records keeping - and how it will improve our future knowledge of underground infrastructure. It will highlight the government and private agencies such as the Ontario Ministry of Transportation, City of Toronto, and Fortis Gas, currently using or looking to implement the use of the standard, and identify how the knowledge learned from that exercise can assist the Shale Energy Industry. Accurate reliable drawings of our underground utility infrastructure produced in accordance with these industry standards is a benefit to all stakeholders -Project Owners, Designers, Utilities, Regulators and Contractors. Further promotion for the use of these standards is the key, if we wish to raise the bar and move forward as an industry.
