Crackmonitoring
Leica Geosystems and Kansai Construction Survey Company
have jointly developed the KUMONOS concrete crack
monitoring system, built around aLeicaVivaTS11 total station.
The system has a built-in concentric crack scale reticule (eye-
piece with cross-hairs).This allows crackwidths to bemeasured
with a combinationofmeasurement through the instrument and
dataonhow far the instrument is away from the crack. Leica says
VivaTS11 total station can be retrofittedwith theKUMONOS
reticule by an authorisedLeicaGeosystems service centre.
“Users can now analyse concrete cracks at a safe distance,
thereby eliminating the need of setting up expensive and time
consuming scaffolding,” saidLeicaGeosystems’ productmanager
Kai Lämmer, “With KUMONOS, crews can remotely inspect
dam, bridge or building facade projects,measuring crackwidths
of 0.3mm, 0.2mm and0.1mm from a distance of 80, 50or 25
m respectively, and simply send digitalised 3D drawings back to
the office. Infrastructure and long term, expensive investments
will be properly protected by using theKUMONOS system.”
This all goes to show that there is a wealth of technology and
expertise available to contractors from suppliers to the concrete
construction industry. And as many case studies illustrate,
getting them on-board early and tapping into their expertise can
have huge benefits.
