Abstract

Purpose

This paper aims to identify the main aspects requiring immediate attention in the post-disaster reconstruction of road infrastructure, thereby providing a major synthesis, which advances the understanding in this important area.

Design/methodology/approach

Literature and empirical evidence obtained from documents and semi-structured interviews with 28 respondents of three case study districts in Aceh, Indonesia was analysed using NVivo 10. The findings were validated through triangulation with the literature and consultation with the experts in the field of disaster management and road infrastructure.

Findings

The authors propose a framework for the reconstruction of road infrastructure, which respond to the peculiarities of road projects in a post-disaster setting. The framework comprises various components requiring detailed attention in the reconstruction process and describes their position in the road project and disaster management cycle.

Originality/value

The framework fills the gap in the body of knowledge with regard to road infrastructure reconstruction in a post-disaster context. For the first time, this paper recognises the importance of local government capacity in the Aceh Province with regard to the sustainability of the post-disaster reconstruction assets.

Abstract

Purpose

This research aimed to determine the differences and similarities in each pilot project to understand the primary design forms and concepts of sponge city concept (SCC) projects in China. It also aimed to examine ten pilot projects in Shanghai to extrapolate their main characteristics and the processes necessary for implementing SCC projects effectively.

Design/methodology/approach

A literature review and field survey case study were employed. Data were mostly collected through a field survey in Shanghai, focusing on both the projects and the surrounding environment. Based on these projects' examination, a comparative method was used to determine the characteristics of the ten pilot SCC projects and programs in Shanghai.

Findings

Six main types of SCC projects among 30 pilot cities were classified in this research to find differences and similarities among the pilot cities. Four sponge design methods were classified into ten pilot projects. After comparing each project size using the same geographical size, three geometrical types were categorized into both existing and new city areas. SCC project characteristics could be identified by combining four methods and three geometrical types and those of the SCC programs by comparing the change in land-use and the surrounding environment in ten pilot projects.

Originality/value

The results are valuable for implementing SCC projects in China and elsewhere and future research on the impact of SCC projects.

Abstract

Purpose

The quantitative assessment of environmental effects should be carried out using the indicators that ensure the best objectivity and efficiency of the environmental impact assessment (EIA) process. The aim of this paper is to clarify the effectiveness of the methods used for prognoses of air pollution from roads. The benchmark method proposed in this paper is based on theoretical knowledge and on analysis of data collected from EIA reports.

Design/methodology/approach

The paper includes a literature review and developing of the benchmark method. This research was based on data dispersion analysis, determination of benchmarks, usage of regression method, as well as confrontation of different methods of determination of air emission concentration used in EIA.

Findings

The simplified model has been designed for determination of concentration of dust emission in the air from motor roads, the building or reconstruction of which is planned. The results indicate that the benchmark method for determination of air pollution with particulate matter PM10 has been elaborated, which can be used for environmental impact evaluation in motor road construction. The method has been elaborated relying on measurement data of existing motor roads and displays a high level of probability of credibility.

Practical implications

The method is simpler and less time‐consuming than the currently used calculation model. It produces a more precise result than the calculation model. It is outstanding and important since the further development of motor road projects can undoubtedly be judged by the results of EIA.

Originality/value

The results of this research provide a rational and comparative approach for finding the methods of determination of the air emission concentration used in EIA in producing the credible outcome. The results reported in the research show existing problems with calculation of emissions from roads. The proposed benchmark method is simple, easy to use and credible.

Abstract

Purpose

The purpose of this paper is to organize the issues that arise during repair processes when the cultural heritage sites and the infrastructure of local residents are simultaneously damaged by disasters and to propose measures before disaster occurrence.

Design/methodology/approach

Issues to be considered regarding restoration processes are extracted based on details of damages and restoration work caused by disasters to the world heritage site “Sacred Sites and Pilgrimage Routes in the Kii Mountain Range” and the surrounding living facilities and hearings from government officials.

Findings

In order to develop a restoration method with little burden on cultural properties, it is important that related institutions collaborate before the occurrence of disasters and consider reconstruction methods with low environmental impact. The authors should increase the number of effective countermeasure options that prioritize harmony with nature and scenery preservation prior to disasters.

Research limitations/implications

Little is known about the best practice of reconstruction work at the cultural heritage sites.

Practical implications

The damages and restoration works which are described in this paper serve as a precedent of recovery works from future disaster occurrence.

Social implications

The damages and restoration works of Yokogaki-toge Pass, the issues extracted and the measures proposed which are presented in this paper would be helpful the people involved in cultural properties to think about better methods of restoration.

Originality/value

In the hearing investigation clarified that both the person in charge of cultural property and public facility management recognize importance learning from many effective countermeasure methods and previous cases to make a better recovery plan for future damage.

Abstract

Purpose

The purpose of this paper is cost optimization of project schedules under constrained resources and alternative production processes (APPs).

Design/methodology/approach

The model contains a cost objective function, generalized precedence relationship constraints, activity duration and start time constraints, lag/lead time constraints, execution mode (EM) constraints, project duration constraints, working time unit assignment constraints and resource constraints. The mixed-integer nonlinear programming (MINLP) superstructure of discrete solutions covers time–cost–resource options related to various EMs for project activities as well as variants for production process implementation.

Findings

The proposed model provides the exact optimal output data for project management, such as network diagrams, Gantt charts, histograms and S-curves. In contrast to classic scheduling approaches, here the optimal project structure is obtained as a model-endogenous decision. The project planner is thus enabled to achieve optimization of the production process simultaneously with resource-constrained scheduling of activities in discrete time units and at a minimum total cost.

Practical implications

A set of application examples are addressed on an actual construction project to display the advantages of proposed model.

Originality/value

The unique value this paper contributes to the body of knowledge reflects through the proposed MINLP model, which is capable of performing the exact cost optimization of production process (where presence and number of activities including their mutual relations are dealt as feasible alternatives, meaning not as fixed parameters) simultaneously with the associated resource-constrained project scheduling, whereby that is achieved within a uniform procedure.

Abstract

Citizen participation has attracted attention in the context of decentralization. In a disaster reconstruction process, a business plan for reconstruction can be modified in line with diversified situations of disaster-affected areas by citizen participation. In Japan, the central government makes a decision about the authority in charge of an overall disaster reconstruction and the budget planning, whereas local governments are in charge of creating and implementing a business plan for reconstruction of each local municipality. Therefore, local governments play an important role in organizing citizen participation to realize the reconstruction that fits reality. It has yet to be shown as decentralization reform and citizen participation system in Japan produce the socio-spatial inequality after the Great East Japan Earthquake. However, it remains to be elucidated how local government and community have to operate the institution about citizen participation during the disaster reconstruction process. I have been doing fieldwork on three tsunami-affected sites in Miyagi Prefecture over past 4 years: Onagawa Town, Higashimatsushima City, and Natori City. I have investigated the social processes of making and implementing a reconstruction plan, and citizen participation. The findings from my fieldwork are as follows: First, citizen participation is based on organizing residents at the community level. Second, traditional community organization (such as neighborhood organization abd industrial associations) contribute to organize residents especially in the emergency phase. Third, as the disaster phase moves, local government and community organization need to change the previous participation frame to ensure residents representation and policy legitimacy.

Abstract

Purpose

Despite the extensive research on post-disaster reconstruction projects (PDRP), there is a paucity of studies that examine critical challenges for the project practices in post-war-developing countries, particularly, Africa. The purpose of this research is to investigate the key project management challenges impacting the post-disaster reconstruction projects (PDRP) during the construction and planning stages in Angola, with an aim to fill the knowledge gap.

Design/methodology/approach

The primary data was collected from 130 project management practitioners working with planning, provincial government organisations including consultants, and contractors within the Angolan public sectors organisations. Response data was subjected to descriptive statistics, mean scores, and inferential statistics (One sample t-tests) and Kendall's concordance.

Findings

The descriptive and empirical analysis demonstrated a disparity of the ranking of the 21challenges affecting the PDRP among the groups; with statistically significant differences amongst the 10 challenges. Based on the overall sample, 6 out of 10 critical challenges are between (24–25) levels of agreement close to the mean. The results of the mean score ranking indicate that “working with poor or restricted access to location”, “project culture that fits the needs of local people”; “improving the capacity of local government”, “minimizing the negative effects of local people” and “relocation issues by establishing property rights during the reconstruction project” were the five critical challenges to managing PDRP whereas “improving information and communication processes”, “securing adequate resources (material and machinery)”, “dealing with rising costs of materials and labour” were considered to be the least critical.

Research limitations/implications

The study was restricted to one province and Country (out of 18) namely, Luanda, Angola. Therefore, the findings may not be generalized to public sector organisations operating in different countries with different contexts, political settings and disaster complexities.

Practical implications

The establishment of challenges in PDRPs helps the key stakeholders by providing the foundation to project teams to address the challenges during planning and construction stages, and thus improving project delivery in the future. Understanding the uniqueness of PDRPs and interdependency of project management from the implementing organization is of particular value for the managers of future projects and other decision-makers, especially in the emerging countries. Moreover, the findings could be used to reflect on the need to formulate policies appropriate to post disaster environments, which among other issues could address building policies, which could include land ownership regulations and procedures together with property rights.

Originality/value

This study contributes to the body of knowledge on the subject within a previously unexplored post-war context with a focus on public organizations perspective. The study provides insights on the challenges affecting the post-disaster reconstruction across the Angolan public sector.
