Results
Comprehensive structural integrity assessment completed safely.
Accurate mapping of reinforcing and condition of brick lining seals.
Non-destructive testing provided reliable data for engineering analysis.
Access systems allowed full survey without disruption to operations.
Project
Solution
Rope access ascent using Hilti mechanical shear set bolts for anchorage.
Use of cover meters to map reinforcing and identify core sample locations.
Bore scope surveys of core sample holes to assess strata and lining seals.
Schmitt Hammer and Impact Echo testing to evaluate material condition.
Structural integrity survey of access ladders and platforms.
Repair of all test holes upon completion.
Project
Challenges
Safe access to a 60m brick chimney stack.
Requirement for detailed inspection of brickwork, lining, and reinforcing.
Need for accurate testing while maintaining the integrity of the structure.
Project
Overview
An integrity survey was completed on the 60m high double brick-lined chimney stack at QAL, working in collaboration with GHD consultants. Rope access and mechanical anchoring systems enabled full inspection of the structure from base to crest, with a range of non-destructive testing methods applied to assess condition and performance.
