“…However, their research lacked the solutions for deviations occurred. Shamkhi and Al-Hajj (2014) analyzed and assessed the significance of mismatches between final drawings and as-built projects in villas, multi-story and industrial buildings. They grouped the reasons causing mismatches into four major categories, including financial problems related to the owners and contractors, the owner's desire to change, inexperienced contractor, incompetent staff, and negligence or using wrong ethics to achieve profits and complexity of the design.…”

“…Many researchers have tried to compare as-planned and as-built drawings using BIM (Kalasapudi et al , 2014; Marzouk and Zaher, 2015; Wang et al , 2014; Lundkvist et al , 2014; Bosché et al , 2015; Shamkhi and Al-Hajj, 2014; Ebrahim et al , 2016), but a few identified the sources of mismatches (Yang and Ergan, 2015; Shamkhi and Al-Hajj, 2014; Akponeware and Adamu, 2017). However, very few works were done, using a BIM approach to provide solutions for these errors considering their roots and the impact of provided solutions on the entire project.…”

Purpose Prompt and effective responses to incompatibilities between as-designed and as-built drawings prevent cost and time overruns and material waste. This paper aims to provide an efficient framework to handle mismatches between these two models with the least negative impact on the whole project. Design/methodology/approach First, 11 most frequent mismatches were identified through questionnaires. Also, the respondents were asked to determine the mismatches’ roots and solutions and the impact of applying solutions on the whole project. Afterward, the process to present the optimum solution to one of these mismatches was modeled. After running the application programming interface developed in Navisworks software, decision-makers access a form, showing mismatches, their causes and solutions, as well as the solutions’ effect. To finalize the optimal solution, a platform was provided on whether to accept the system solution or to propose an alternative. Findings To empirically validate the reliability of the proposed framework, two projects were investigated. Two different approaches to dealing with the same mismatch occurred in these projects were compared in terms of time, cost and material required. The results showed that addressing the mismatches through the proposed framework can efficiently enhance time, cost and material consumption, in comparison with the traditional approach. Originality/value There is currently no building information modeling-based holistic framework for managing mismatches between as-designed and as-built drawings. The results of this research can help contractors to make the best decision, saving project resources, when setting about a mismatch during construction.
