New Accreditation Services on Underground Utility Survey

To facilitate the construction industry to plan and conduct the underground works efficiently, Department of Land Surveying and Geo-informatics of The Hong Kong Polytechnic University had developed a series of local test standards for six non-destructive testing methods for surveying, imaging and diagnosis (NDTSID) applied in underground utility surveys. The six NDTSID methods include (1) electromagnetic pipe cable locating, (2) ground penetrating radar, (3) Laser scanning survey, (4) visual inspection, (5) leak detection by acoustic methods, and (6) flow survey & monitoring for drains/sewers. Water Supplies Department and Drainage Services Department are considering applying these NDTSID techniques in their projects and also requiring relevant testing laboratories to obtain accreditation. A high demand for accreditation services on underground utility survey is thus anticipated. HKAS now offers accreditation services on underground utility survey in accordance with these local test standards. HOKLAS Supplementary Criteria No. 55 (HOKLAS SC-55) was also issued on 1 November 2021 to lay down specific accreditation requirements for these tests.
