“…It also highlights that the three most heavily affected regions in terms of the number of pupils and reconstruction fund allocations are Batticaloa, Galle and Ampara. These three regions were highlighted by posttsunami field surveys to have sustained some of the greatest losses (Jayasuriya et al, 2005;Palliyaguru et al, 2007;Rossetto et al, 2007) and largest levels of tsunami inundation following the 2004 event (Goff et al, 2006;Wijetunge, 2012). They are the regions of focus for the RESCOOL RVS implementation.…”

The 2004 Indian Ocean tsunami affected 5% of Sri Lanka’s schools, severely damaging 108 and destroying 74. The catastrophe highlighted the critical role of schools in providing educational continuity during community recovery. Sri Lanka has since rehabilitated and rebuilt most of the destroyed schools along the coastline. However, there is a limited understanding of current levels of school exposure to tsunami. This hampers preparedness and risk reduction interventions that can improve community and educational tsunami resilience. This paper presents a multi-disciplinary school exposure database relevant to both vulnerability and loss modelling. The repository includes data on 38 schools and 86 classroom buildings, surveyed across the coastal districts of Ampara, Batticaloa and Galle in Sri Lanka, which were heavily affected by the 2004 tsunami. A new engineering rapid visual survey tool is presented that was used to conduct the physical assessment of schools for the exposure repository. School damage mechanisms observed in past tsunami inform the survey forms, which are designed to capture information at both school compound and building levels. The tsunami engineering survey tools are universally applicable for the visual assessment of schools exposed to tsunami. The surveys show that most Sri Lankan school buildings can be classified into three building archetypes. This means that future risk assessments can be conducted considering a small number of index buildings that are based on these archetypes with differing partition arrangements and structural health conditions. The surveys also raise three significant concerns. Firstly, most schools affected by the 2004 tsunami remain in the same exposed locations without any consideration for tsunami design or strengthening provisions. Secondly, Sri Lankan schools are fragile to tsunami loading and many of the schools in the Galle district suffer from severe corrosion, which will further affect their tsunami vulnerability. Thirdly, schools do not appear prepared for tsunami, and do not have adequate tsunami warnings nor evacuation protocols in place. These observations raise the urgent need to mitigate tsunami risk, including a holistic plan for tsunami retrofitting and for interventions to improve the tsunami preparedness of schools in Sri Lanka.

The research aim is to critically evaluate the content validity of the functional building performance evaluation criteria using the Content Validity Index (CVI) and modified kappa statistic. The selection of relevant criteria for functional building performance evaluation should be managed effectively by the building management team because it is strongly related to the achievement of organizational objectives and the building occupants’ satisfaction. Studies over the past decades have shown that the criteria vary, relying on the intention of conducting the performance evaluation and the types of building. These selection criteria have a direct impact on the functional building performance and need to be done systematically. Thus, the content validity of the functional building performance evaluation criteria is a necessary step in instrument development. To achieve this research aim, the instrument has been developed based on numerous construct items that have been obtained from previous studies by various authors and established rating tools or standards. The sample of the respondents for content validation comprises of seven (7) expert panels in the area of historic building management and building performance evaluation, such as from the local municipality, related government agencies, academician and building management team. The panels reviewed and rated the instrument to ensure its relevance and the representativeness of each item. The result shows that a total of 39 items are valid and are considered to be retained, and will be further tested in the next study. The result has also shown that the Scale level – CVI/ Averaging calculation method (S-CVI/ Ave) for all items has met the criterion of 0.90. Significantly, content validity should be treated as important because it provides adequate and acceptable items of the content domain

Designing a construction supply chain model using backup supplier aiming at optimizing resiliency against disruption

Resilience is a topic that has recently emerged concerning the basics of the construction project supply chain and we can consider it as a response to disruption in the supply chain of the project. Disruption also is an unavoidable reality in today’s complex and dynamic construction supply chain, the occurrence of which can cause irretrievable damages to the system, such as financial losses. Successful companies seek to minimize disruption and maintain adequate supply chain performance before disruption occurs, rather than looking for costly and challenging post-disruption solutions. This paper covers this gap by proposing a scenario-based mixed integer-programming model aiming to minimize logistics costs and delays, while scheduling projects to address selecting the appropriate supplier at risk of disruption. So far, this quantitative view was not presented in discussions about disruptions in the project supply chain, therefore different scenarios are applied in the process to validate the model. To improve its resilience level, this model benefits from back-up suppliers’ strategy. This study focuses on providing the required materials for the project site in an emergency without incurring additional costs using a back-up supplier. Results reveal the model’s suitability in confronting the unavailability of a supplier due to disruption.
