Analysis of Causes of Delay in Middle and High Income Self-Build Housing Projects (SBHPs) in Wa, Ghana

Self-build housing projects (SBHPs) among middle and high income developers are faced with many challenges that cause delay in the delivery time of the house(s). The focus of this paper is to analyse the factors that cause delay in SBHPs in order to identify the critical delay factors. Review of literature and expert input revealed 20 variables which were used in a structured questionnaire for data collection from owners, consultants and builders in Wa Municipality. Reliability test, t-test analysis and mean ranking were used in the data analysis. The results revealed that “Delay in obtaining permit from Local Authorities” was the first delay factor followed by “Poor site management and supervision”. The delay factor ranked least was “Inadequate cost estimation and related details” from consultants. The paper recommends that Government agencies that regulate physical development should intensify public education, particularly on responsibilities and obligations, especially among self-builders. The paper recommends further study into labour-related issues as well as communication and information management among participants and its impact on self-build project success.

A Consideration of Issues in the Government＇s Public Housing Projects in Post-War Iraq

Post-war Iraq is a mix of potential opportunities, promising intentions, and difficult challenges. After 2003, the government adopted a program to manage the housing crisis and satisfy housing needs. Through a fieldwork survey, we aimed to present this program by reviewing the government targets, main housing problems, governmental legislations, and construction process. We found that the government abandoned its centralized role in its National Housing Project as it opened the door of Iraqi housing market to foreign and local investors. We also found that, considering the enormous need for housing the occupancy rate of the governmental housing units are so low and construction is also generally slow. We deduced that the pricing model of the government＇s national housing project is far from our general notion of public housing for low-income post-war people. Moreover, it is necessary for the government to formulate a clearer strategic vision and to adopt more innovative approaches to address effectively and rapidly the trade-offs of the short and long terms objectives of the reconstruction process in post-war Iraq.

Evaluation of Large-Scale Housing Projects in Terms of Their Compatibility to Criteria of Environmental Design

The design and execution of large-scale housing projects always have negative environmental impacts in terms of excessive consumption of non-renewable energy resources and environmental pollution. These negative impacts are multiplied in the case of large-scale housing projects where a large number of standardized units are implemented in a repeated manner. This proposed paper will study and evaluate the environmental impacts of large-scale housing projects according to criteria of environmental design. The case study project is Haram City that is a housing project for small low-income families. The project consists of 50,000 housing units and is located in 6th of October City, which has a hot dry desert climate that necessitates special design considerations and applications of environmental design concepts. The project will be analyzed and evaluated in terms of site layout, design of buildings, orientation, materials used, construction techniques, thermal behavior, landscaping, etc.

Factors Influencing Post-disaster Reconstruction Project Management for Housing Provision in the Gaza Strip, Occupied Palestinian Territories

In the Occupied Palestinian Territories, the Gaza Strip has suffered regular cycles of reconstruction due to systematic destruction during Israeli military operations, as in 2006, 2008–2009, 2012, and 2014. In this context of ongoing conflict this article aims to identify, rank, and discuss the most important factors influencing post-disaster reconstruction project management(PDRPM) for housing in the Gaza Strip. A set of key factors that influence PDRPM were assembled as a result of a global literature review. A questionnaire survey was conducted, and the obtained data were analyzed using a relative importance index for each PDRPM factor. Findings are presented in six groups: housing approaches, organizational behavior, project funding, supply chain and logistics, communication and coordination, and PDRPM context. Findings indicate that the most significant factors that influence PDRPM for housing provision in the Gaza Strip are related to issues associated with financial resources. It is critical that sufficient funding should be available in order to allow organizations to undertake housing projects in an effective and efficient way. Joint efforts are required from international donors and local organizations in order to effectively manage financial resources with the ultimate goal of improving PDRPM for housing provision.

An Inquiry into Success Factors for Post-disaster Housing Reconstruction Projects: A Case of Kerala, South India

The 2004 Indian Ocean Tsunami triggered significant destruction to housing and related infrastructures across various coastal districts of south India.Research shows that tsunami reconstruction projects in Kerala experienced different degrees of success and failure.On this background,this study explored factors that contributed to the successful implementation of tsunami housing projects in Kerala by(1)consolidating various critical success factors(CSFs)for post-disaster reconstruction(PDR)projects under‘‘project management success traits’’through content analysis of existing literature;(2)deriving a conceptual model that envisages project success in PDR contexts;and(3)assessing the impacts of those success traits on tsunami housing projects using confirmatory factor analysis.Necessary data were gathered through a survey of various stakeholders involved in tsunami reconstruction projects in Kerala using structured questionnaires.The research revealed that PDR project success is attributed to critical dimensions of project management such as institutional mechanisms,reconstruction strategies,project implementation,and stakeholder management.A conceptual model with the interplay of project success,success traits,as well as their CSFs identified the project management actions that must be monitored during reconstruction.Since the project management approach is widely recognized for PDR projects,these success traits hold huge potential for effective organization and management of housing reconstruction projects.The study also helped to identify project management traits that need improvements for the successful implementation of post-disaster housing projects in Kerala.Thus the research findings can serve as a foundational study for formulating project management strategies appropriate to PDR projects in Kerala.

城中村租赁住房品质提升研究

城中村在满足我国城镇化进程中流动人口住房需求方面作用突出,但租赁品质普遍有待提升。在中央加快推进“三大工程”建设的背景下,提升城中村租赁品质对于建设“四好”、推动城市更新,乃至加快实现“租购并举”、构建房地产发展新模式均有重大意义。本文首先梳理城中村租赁品质存在的突出问题,指出现有改造模式存在无法满足新市民、青年人租赁需求的弊端。随后提出加强城中村改造与保租房供给联动是可行方向,通过案例分析论述了统租改造实践中存在的困境。在此基础上,提出以下对策建议:明确房屋改造和出租标准,完善管理规范;拓宽多元化投融资渠道,优化成本分摊方式;采取政府统筹、市场化主导策略,创新谈判机制;探索城中村受托和平台业务,输出增值类服务。
