“…The structured survey questionnaire was constructed based on a review of the literature and unstructured face-to-face interviews with experts in cost estimation. A comprehensive list of potential factors affecting cost estimate accuracy during design and applicable in Jordan was compiled from the following studies: (Tymvios et al , 2012; Hatamleh et al , 2016; Adafin et al , 2016; Arif et al , 2015; RICS, 2012; Bredehoeft, 2012; Enshassi et al , 2013; Farinloye et al , 2009; Azhar et al , 2008; Odusami and Onukwube, 2008; Towner and Baccarini, 2007; Liu and Zhu, 2007; Enshassi et al , 2007; Dysert, 2006; Babalola and Aladegbaiye, 2006; Iyer and Jha, 2005; Elhag et al , 2005; Shash and Ibrahim, 2005; Al-Shanti, 2003; Madi, 2003; Trost and Oberlender, 2003; Mochtar and Arditi, 2001; Ling and Boo, 2001; Skitmore et al , 2000; Akintoye, 2000; Akintoye, 2000; Gunner and Skitmore, 1999; Al-Thunain, 1996; Al-Khaldi, 1990; and Skitmore et al , 1990).…”

Purpose The purpose of this paper is to identify factors affecting cost estimate accuracy in each of five design stages preceding building construction: order of magnitude, conceptual/schematic, detailed design, construction document and bid phase. Design/methodology/approach Data were collected using an online survey completed by 138 respondents who work in design consultancy firms in Jordan, including project managers, architects and quantity surveyors (QSs). Survey responses were analyzed using descriptive statistics. Confirmatory interviews and case study comparisons were used to confirm the statistical analysis results. Findings The results of this study indicated that each design stage’s cost estimate was affected by several factors. Two significant factors were common across four of the five design stages: client experience and project team experience. In addition, a high level of agreement was observed among the project managers, architects and QSs regarding the factors affecting cost estimate accuracy. Originality/value Accurately estimating building construction costs during the design process has posed a challenge for designers and their clients in Jordan. Despite the care and effort involved in preparing cost estimates in each of the five design stages, deviations are commonly observed. Because the accuracy of building construction cost estimates directly affect the success or failure of a project, the results of this study can be used to reduce uncertainties in building construction cost estimation and subsequently increase the likelihood of project success

Abstract:As a sustainable construction method, prefabrication has become popular in many nations. However, there are many challenges for prefabrication, especially in terms of cost. Previous studies have revealed that higher capital cost was the most important barrier to the implementation of prefabrication. Thus, the objective of this study is to explore and evaluate the critical factors affecting the capital cost of prefabrication and examine how cost management may be affected by the "experience", "corporate responsibility", and "participant function" as a fix independent factors. To achieve the research objective, semi-structured interviews were conducted with 11 experts for the development of the questionnaire. Then, a questionnaire survey was conducted to investigate the significance of 49 factors related to prefabrication capital cost. The survey results revealed that "Specification and standards for prefabricated building design", "Related experience of manager", and "Rationality of precast component split" were the most critical factors. In addition, "experience", "corporate responsibility", and "participant function" had significant impact on the evaluation of capital cost factors. The findings can facilitate developing a benchmark framework for exploring the factors affecting the capital cost of prefabrication in China.

Cost estimation in construction project is very critical for avoiding cost overrun in the project. This paper aims to provide a basis for improving cost estimation performance in construction through a systematic review of previous studies for last 31 years. The papers have identified a total of 238 construction cost estimation papers in 23 journals. Only 33 papers focused on factors influencing the performance of cost estimation. These papers were then analyzed, synthesized, and summarized in terms of the distribution across countries and citation influences. The factors of cost estimation performance were clustered to several themes with most of the factors in control themes. The factors in control themes are cluttered based on Organizational Control Theory (OCT). However, control themes provide less conceptual basis and dynamic to explain cost estimation performance and relationship among the factors. Therefore, this study reclassified other factors of cost estimation performance with reference to Contingency Theory (CT) and Task-Technology Fit Theory (TTFT). Hence, a new framework with relationship among the factors and cost estimation performance was developed. Further development and research of using the CT and TTFT frameworks were also discussed.
