Undertake survey works to identify the tendon and their positions within the prestressed beams so that the structural engineer can assess its loading capability.
Survey scan one typical internal beam and one edge beam per bridge.
Scans were performed to one typical internal beam and one edge beam per bridge using the Hilti PS1000X-scan on 600 x 600mm grids. The scan data from the Hilti PS1000X-Scan displayed arrangement of the pre-stressing strand and corresponded well to the notified Type T7 beams from the previous clients assessment report There is a significant amount of distribution reinforcement also present at a cover depth of approximately 50 mm. Edge beam soffit scans display a similar arrangement.
