Purpose The primary objectives of this study are to (1) highlight subsectors and industry groups of the construction sector that are most vulnerable to weather-related disasters (with highest labor cost escalation) and (2) analyze how immediate this labor wage escalation happens in different subsector of the construction sector. Design/methodology/approach The research methodology consists of three steps: (i) integrating various data sources to enable measurement of the county-level labor wage changes following large-scale weather-related disasters; (ii) measuring postdisaster labor wage changes at the county level; and (iii) comparing amount and timing of postdisaster labor wage changes among all sub-sectors (and industry groups) of the construction sector. Findings The results show that among the three construction subsectors (Heavy and Civil Engineering Construction subsector, Construction of Buildings subsector, and Specialty Trade Contractors sub-sector), Heavy and Civil Engineering Construction subsector is the most vulnerable to weather-related disasters. The industry groups under the Heavy and Civil Engineering Construction subsector showed the same vulnerability level; however, under the Construction of Buildings subsector, Industrial Building Construction industry group showed to be the most vulnerable; and under the Specialty Trade Contractors subsector, the Building Foundation and Exterior Contractors industry group is the most vulnerable. The results also showed that in approximately 75% of the damaged counties, there were increases in wages of all construction labors, over the following three quarter after the disasters. In average, labor wages in Construction of Buildings subsector and the Specialty Trade Contractors subsector decreased by 0.6% and 0.8%, respectively, in the quarter of disaster and gradually increased by 4.4% and 4.6%, respectively, in the following three quarters. On the other hand, Heavy and Civil Engineering Construction’s labor wages did not experience this decrease right after the disasters; wages increased immediately after disasters hit the counties and continually increased by 8.6% in three quarters after the disasters. It is expected that the results of this study will help policy makers, cost estimators and insurers to have a better understanding of the post-disaster construction labor wage fluctuations. Originality/value This study is unique in the way it used construction labor wage data. All data are location quotient, which makes the comparison among the affected counties (with different construction size) feasible.


For thousands of years, construction engineering has played a vital role in the advancement of human civilization. Humans have always aspired to build taller, grander, and more robust constructions either for civilian purpose or to defend cities and towns from invading armies. The architectural splendour of the pyramids in Egypt and the Great Wall of China are not only awe-inspiring examples for the engineering feats of the ancients but also remarkable for the robustness in evidence for having stood the test of time for over thousands of years since these were built. Modern civil construction engineering, too, requires optimum resource utilization, speed of execution, and adherence to best engineering practices. The rapid strides made in information technology makes it possible for architects and engineers to achieve those goals. This chapter discusses the role and impact that information technology has in the domain of civil engineering and construction sector.

Civil engineering contractors encounter serious challenges in order to sustain their businesses, especially in a weak economic climate.  A certain level of construction experience, expertise and training are required to manage a sustainable construction company.  The Construction Industry Development Board (CIDB) was established in 2000 as a statutory body to provide leadership to stakeholders and stimulate sustainable growth, reform and improvement of the construction sector for effective infrastructure delivery and improvement of construction skills. The objectives of this research were to investigate challenges faced by civil engineering contractors whilst making their enterprises sustainable.  Contractors’ views were presented at “Construction Indaba 2011” held on 1–2 June 2011 and hosted by eThekwini Municipality’s Business Support, Tourism and Markets in Durban KwaZulu-Natal. Discussion and findings revealed to a skills’ shortage in the construction section and underlined the need for continuous training of the contractors’ employees. The South African government in conjunction with all stakeholders should develop and implement contractor programs to address the lack of technical and management skills in the construction sector.

Green building practice has been gaining its popularity nowadays due to its significant benefits in protecting environment from threat caused by construction activities. It appears that there is a poor perception among construction players about green building in Indonesia. The students also play an important role in the development of construction especially green building in the future. This study aims to analyze the students’ perceptions of civil engineering and architecture students of University of Sriwijaya towards green building practices. The questionnaires were used for data collection which covered the basic understandings, criteria, benefits, and challenges of green building. There were about 240 respondents consisting of 153 from civil engineering and 87 respondents from architecture. The validity and reliability tests were conducted. The results showed that there is a positive impact on the perceptions among students towards green building adoption. Based on the analysis, the major benefit perceived by students was to reduce construction waste with a mean value of 4.67. Therefore, the reduction of construction waste will minimize the environmental damage and conserve natural resources. It was also found that the lack of knowledge from project team members about green building became the most significant challenge towards green building practices based on students’ perception. This study could offer valuable information related to benefits and challenges towards green building implementation among university students so that university could improve teaching materials and methods by applying the current issues in the construction sector.
