Readers Response, Draft #2
In the webpage "Hotel New World Collapse," Kayat (2012) explains the various theories and reasoning behind the collapse of the Hotel New World. There were a few speculations made by the engineers who examined the collapse during the investigations that followed. According to Klimkowski (2005, as cited in Kayat, 2012), a possible act of terrorism, strength of the material used or even the composition of the soil might be some of the reasons behind the hotel's fall. However, these assumptions were eliminated as the engineers evaluated all of these areas and were able to prove that another reason was responsible. Neale (2001, as cited from Kayat, 2012) mentioned that the collapse was due to 'under-designed columns and foundations' as the building's original engineers excluded the building's weight, which was part of the dead load calculation. The same cited author concluded that overloads, lack of proper maintenance and poor engineering contributed to the collapse.
The article mainly explains the speculation and forensic studies following the collapse of the Hotel New World. However, the inadequate information on the causes that led to the fall of the hotel, makes the article fall short in pleasing the readers.
Firstly, one of the main causes that led to the collapse of Hotel New World was the poorly done calculations and drawings of the building made during the design stage. According to the Report of Inquiry, Thean (1987), ‘R.C. calculations are sketchy and insufficient, and the R.C. drawings show many discrepancies and ambiguities in the technical details and other information given. ‘For example, the reinforcements of the structural members shown in the RC drawings were significantly lesser than those obtained from the calculations. Furthermore, in the webpage "Hotel New World Collapse," Lim (2011) mentioned that “the building’s architectural plans and structural drawings were drawn up by unqualified draughtsmen” and that the entire construction of the building was supervised by the owner himself. In my opinion, if people with the right competencies were hired to plan the layout of the building, the structural members of the building would not have given way.
Another significant factor that led to the fall of the building, was the unacceptable quality of construction the building underwent. The inquiry states that ‘No soil tests or concrete cube tests were carried out,’ and even if some of these tests were carried out it was probably done without protocol as numerous plies and columns were not positioned accordingly. From my perspective, these piles and columns are the basic foundations to support the entire building and if these important components of a building were not taken seriously, it will certainly cause the structure to crumble.
Thirdly, the inquiry also mentioned that the Hotel New World did not undergo any proper maintenance. The building owner did not have proper work done when there were persistent cracks noticed on the columns, walls, and floors of the building. The cracks were either disregarded or perfunctory patched up. According to the inquiry, ‘No professional advice or assistance was sought by the owners who were probably ignorant of the serious structural deterioration of the building.’ Hence, the cracks within the columns continued to spread. In my opinion, if the building owner had taken proper measures, the structural problems in the building could have been rectified.
In conclusion, the Hotel New World was a ticking bomb bound to collapse, as there were already issues with the drawings and calculations of the building. Moreover, if a group of individuals with the right competency had supervised the construction and maintenance of the building, the tragedy of Hotel New World could have been avoided.
