Purpose This paper aims to determine the responses of construction organisations to the Coronavirus (COVID-19) pandemic and its associated lockdown and the impact on the South African construction industry (SACI). Design/methodology/approach The study adopted a quantitative survey with responses sought from 825 contracting organisation’s representatives drawn from the database of the construction industry development board. The data gathered were analysed using percentage, mean item score and one-sample t-test. The reliability of the research instrument was also tested using the Cronbach alpha test. Findings Findings revealed that most construction organisations implemented a complete travel ban and halting all business operations on sites and offices in a bid to curb the spread of the virus. Furthermore, whilst most construction organisations envisage significant disruption in their project delivery, the problem of job losses was regarded as a short, medium and long-term impact of the pandemic. Loss of revenue, a decline in the economy and business interruption are also some of the potential impacts of the COVID-19 pandemic on the SACI. Originality/value The study’s findings give practical insights on the potential impact of the pandemic on the construction industry and the possible approach needed to help cushion the effect on the industry.

<p>The Cenozoic growth of the Ecuadorian Andes has been strongly influenced by the compressional reactivation of inherited crustal anisotropies, strike-slip faulting and uplift, and the erosional effects of a wet tropical climate superposed on the deforming orogen. Some authors have linked uplift in the Western Cordillera to the interaction between the South American Plate and the subduction of the oceanic Carnegie Ridge. However, recent studies have alternatively suggested that the tectonic evolution of a northward-escaping crustal sliver in western Ecuador along the Pallatanga strike-slip zone may equally well explain mountain building and topographic growth in this region. While the importance of the Pallatanga Fault has been recognized in the context of seismic hazards, its long-term impact on the development of topography and relief has not been explored in detail. To evaluate the possible roles of oceanic ridge subduction and/or strike-slip motion in prompting the growth of the Western Cordillera, we present new thermochronological data to constrain the deformational history of the Western Cordillera at different latitudes. We focus on two sites in the vicinity of the Pallatanga strike-slip fault (3°S and 1°30’S) and a location farther to the north (0°30’N). Our apatite and zircon (U-Th-Sm)/He dates range from 26.0 ± 0.4 Ma to 3.9 ± 0.1 Ma and from 23.7 ± 0.3 to 5.9 ± 0.1 Ma, respectively. The three sampled sites record a clear age-elevation relationship. The inverse modeling of apatite and zircon (U-Th-Sm)/He dates and upcoming apatite fission-track data is expected to provide new constraints on the recent uplift and exhumation history of the Western Ecuadorian Andes and thus furnish information on the paleo-geographical evolution of the northern Andes.</p>
