Real-time high-rise building monitoring system using global navigation satellite system technology

Abstract

The continuous assessment of the displacement of a high-rise building enables veri cation that meets the structural assumptions calculated in the project, which provide an additional useful feedback for structural engineers. Unexpected structural responses during the phases of construction or once the building is in use can help detect current and future problems as well as providing cost savings. It also contributes to an improved risk management for natural phenomena; it can be used to verify the stability of the structure providing an additional safety item for the building. The technology improvement of GNSS techniques has allowed us important advancements of Gaussian methodology applied to control the dynamics of building structures in real time, especially for calculating, controlling and interpreting of satellite survey measurements based on Gaussian Analysis and least squares adjustment. The Real-Time monitoring system works by implementing a local geodetic network with GNSS technology on the structure to be monitored. Algorithms are then applied that improve the compensated network solution and this is integrated into original software. The system allows us to achieve a high level of security and e ective risk management in real time because for each building a unique mathematical model is designed that allows GNSS position errors to be reduced. In the case of Torre Espacio the overall mathematical adjustment model reduces the maximum error by 40%. The system has been installed on a high-rise building called Torre Espacio, in Madrid, Spain and is fully operational.

Estimation of the Lateral Dynamic Displacement of High-Rise Buildings under Wind Load Based on Fusion of a Remote Sensing Vibrometer and an Inclinometer

“…The second category of displacement measurement methods refers to global position systems (GPS) [12][13][14][15][16][17], vision systems [18][19][20][21], radar systems [22][23][24], and laser systems [25,26]. These systems can provide accurate displacement in a noncontact manner.…”

Hybrid Wavelet and Principal Component Analyses Approach for Extracting Dynamic Motion Characteristics from Displacement Series Derived from Multipath-Affected High-Rate GNSS Observations

“…However, although previous studies accepted the accuracy of GNSS-PPP for estimating the dynamic components of motions, there is a lack of studies on the effect of multipath errors and observation noises on the results, as most of the PPP method testing was conducted in open sky areas [6,9,10]. The GNSS multipath errors and noises for static and dynamic movements are presented and discussed in [11][12][13], where the geometry of satellites and reflective surfaces are the main parameters affecting the multipath [14,15].…”

Smartphone-Based Data Collection System for Repetitive Concrete Temperature Monitoring in High-Rise Building Construction

“…Accurate and timely management of on-site information in high-rise building construction is a crucial element for the success of a project [1]. In high-rise construction, a large amount of real-time information is available because various tasks are performed simultaneously [2]. If on-site information for timely management is missing or delayed in transfer, subsequent processes may in turn be delayed or rework may be required [3].…”
