Vertical alignment in high-rise building is a very important aspect. In order to manage the
growing demand for spaces in urban cities, the people are now interested in construction of
super high-rise buildings. The architects are nowadays interested in improvising untypical
complicated morphology in building designs which increase the difficulties in surveying for
vertical alignments. Consequently the surveyors are themselves forced to find alternative
survey techniques to manage the difficulties. Though the GPS survey techniques are
applicable like in other constructions, the majority of the construction society is still
depended on the traditional survey methods.
As per the existing data sources, operational and spaces related challenges of GPS surveying
are common for any kind of GPS applications; and though the GPS survey techniques are
applicable for vertical alignment in high-rise buildings, there is lack of data sources to
explicitly expose the applicability of different GPS survey techniques and the challenges to
be considered in such applications. This study has been oriented to find out the best suitable
GPS survey technique for the vertical alignments in high-rise buildings by checking the
applicability of all five basic GPS techniques with their accuracy, efficiency, time
consuming and cost implications while focusing on identifying further practical challenges
apart from the already identified operational and space related problems.
The findings prove that the GPS techniques can be used for vertical alignments in high-rise
buildings and the best technique among them is Static GPS with the combination of
traditional survey methods; and there are some practical challenges to be considered in such
GPS applications for vertical alignments in high-rise buildings. The findings have been
attained by analyzing the reliable data gained through experts’ comments, case studies and
experiments. |
