Abstract

The overall aim of this study is to improve construction quality in Nigeria through the identification of pertinent factors affecting the process. Relevant factors were identified from the literature and studied by means of questionnaire survey sent to construction industry professionals that include architects, engineers, quantity surveyors and builders. The importance of each factor was computed for all the professionals via the severity and frequency responses of the factors. Data analysis includes ranking comparison among the professionals using severity, frequency and importance indexes. Percentage rank agreement factor (PRAF) was used to measure agreement of the importance ranking among construction professionals and one sample t-test was conducted to determine the significance of each factor. Finally, correlation analysis was used to measure the degree of correlation among all professionals.The results shows that the five most important factors are ‘poor quality of materials delivered to site’, ‘lo...

影响尼日利亚建筑质量的关键因素:来自行业专业人士的证据

本研究的总体目的是通过确定影响施工过程的相关因素来提高尼日利亚的施工质量。从文献中确定相关因素，并通过向建筑行业专业人士(包括建筑师、工程师、工料测量师和建筑商)发送问卷调查的方式进行研究。每个因素的重要性是通过对这些因素的严重程度和频率的反应来计算的。数据分析包括使用严重性、频率和重要性指标对专业人员进行排名比较。采用百分比等级一致性因子(PRAF)衡量建筑专业人员重要性排序的一致性，并采用单样本t检验确定各因素的显著性。最后，采用相关分析来衡量各专业之间的相关程度。结果表明，五个最重要的因素是“交付到现场的材料质量差”，“低……”
