Assessing Consequences of Change Request Impact in Construction Industry of YEMEN: An Explorative Likert-Scale Based Survey Design
针对也门线性建筑项目，设计了一份基于21项基准标准的调查问卷，从变更请求影响的严重性、后果确定性和预防策略三个维度收集行业数据，以评估变更影响后果。
The linear construction projects of YEMEN are the basis of the study, focussing on the requirement of change orders in the several stages of the projects. The work presented here is defining the potential survey questioner to obtain the reliable and optimal data from construction industry of YEMEN. The data obtained will be used further to assess the change impact consequences and possible directions of prevention. The overall survey planned in 3 dimensions and they are finding the severity and scope of the change request impact, consequence certainty of the change request impact and the preventive strategies followed to avoid the consequences of the change request impacts. The overall 21 benchmarking functional and non-function construction standards are defined to prepare the questioner and the same is used to obtain the construction industry opinion, beliefs and practices through the said three dimensions of the survey.
