| Summary: | Deformation of engineering structures is often monitored in order to ensure
that the structure is exhibiting a safe deformation behavior. The deformation of highrise
building can be monitored using geodetic surveys and geotechnical/structural
measurements. Geodetic surveys include conventional (terrestrial) and satellite
(Global Positioning System); wherelse geotechnical/structural measurements are
detected either by using leasers, tiltmeters, joint-meters or micrometers. This
research discusses the capability of monitoring high and low-rise building structure
using geodetic surveys (conventional and satellite) and geotechnical measurement
(crack width measurement). Two buildings namely the Twin Tower and Innovation
Centre Building of University Technology MARA (UiTM), Selangor, Malaysia were
chosen for this research. Five control stations have been established around the
UiTM Twin Tower Building for the purpose of monitoring and another nine points
for the Innovation Centre Building. The monitoring exercises were carried out at four
(4) different epochs. The Terrestrial and Global Positioning System (GPS) dataset in
the monitoring exercise were processed and analysed using the Trimble Geodetic
Office (TGO) survey software. Generally the monitored points for the Twin Tower
Building experienced movements within 1 mm to 10 mm. For the Innovation Centre
Building monitored points seemed to shift between 1 mm to 9 mm. Detection of
movement for both building structures seemed to be within the allowable tolerance.
It is shown that monitoring of building structures using the techniques adopted in this
study has significant advantages and disadvantages.
