“…Other analytical systems comparisons have involved the use of graph theory to abstract and track the accumulation of error in pipes. This technique, as outlined by Kalasapudi et al [23], requires establishing a comprehensive tolerance network associated with each pipe element and subsequently quantifying and comparing the errors of each associated pipe element. In summary, while several innovative techniques can be used to abstract errors in pipe spool assemblies, oftentimes, these approaches are far too comprehensive to adopt for real-time DQA of termination points.…”

Increased prefabrication and modularization have resulted in fabrication shops producing more complex assemblies with tighter tolerances. Most measurements in fabrication shops are still done using manual tools that are not accurate enough for engineering tolerance specifications, which can lead to rework. Three dimensional (3D) scanning and measurement systems can provide increased accuracy and digital integration capabilities, however they do not sufficiently support fast and accurate dimensional quality assurance (DQA) of pipe spool fabrication. This is because no dimensional quality assurance methods to date have focused solely on termination points for pipe spool assemblies. In the present article, a new scan-vs-BIM method is developed to accurately estimate termination points for 3D scanned cylindrical assemblies. This method relies on statistically fitting circular features at termination points and thus eliminating conventional issues with target placement for laser trackers and measurement readings for tape measures. The method is tested in an industrial-scale experiment, where 30 pipe spool assemblies were fabricated, and more than 400 quality control steps completed. The accuracy of termination point detection was benchmarked against results from a laser tracker and compared against commercial scan-to-BIM software. Results show that the developed method has an average accuracy of 1.01 mm and is significantly better than the scan-to-BIM software with an average accuracy of 4.75 mm.

“…Since automation of analyzing as-built data and subsequent comparison with BIM requires developing bespoke algorithms for specific feature abstraction (i.e., planar features are extracted in a different manner than cylindrical features), most research is focused in key areas of construction objects. For instance, there are distinct workflows developed for automated extraction and evaluation of precast concrete elements [25], cylindrical objects such as pipes [31,32], steel structures [33], and architectural features such as doors, stairs, and walls [34]. Despite the growing availability of these approaches and integration into widely available commercial software, the current quantification process observed in industry is still reliant on manual methods and techniques [35].…”

Dimensional quality plays a key role in project success for modular construction. While approaches exist for reducing rework associated with dimensional variability in traditional construction (i.e., onsite resolution), more proactive approaches must be employed during offsite production of modules. Unfortunately, the stricter dimensional quality demands in modular construction are not yet completely addressed in existing guidelines or studies. As such, contractors often must resort to use of reactive measures to reduce rework. This paper bridges this gap by demonstrating how to implement continuous benchmarking and improvement of dimensional quality by comparing as-built and nominal 3D geometric data across modular construction projects. A case study is presented for two nearly identical modular construction projects, which are carried out in succession. The first project is used to quantify and benchmark key impacts on overall dimensional quality, while strategic improvements are introduced in the second project to improve quality and reduce rework. The results of this study demonstrate how contractors can achieve adequate dimensional quality and reduce rework on successive modular construction projects.

“…For example, since the process in the design phase is iterative, the content and structure of design information is subject to continuous change [95]. Poor change coordination may interrupt the decision-making processes in other phases of construction projects [96]. Hence, openness to change is an essential management factor for different stakeholders when dealing with BIM-related issues [97], as Dulewicz and Higgs [13] claimed that dealing with different levels of change (low, moderate, or high change) can be done more satisfactorily by a specific leadership style.…”

The use of new, digitally enabled innovations, such as building information modeling (BIM), raises issues such as the delineation of a competent leader. Even though BIM-based competency assessment models have become essential tools for maximizing the potential values of BIM implementation, the current competency models provide limited focus on leadership aspects that facilitate and enhance the BIM implementation efforts. This paper seeks to identify the specific competencies required for BIM implementation and examines the relationships between these competencies. Thirty-two experts from around the globe investigated a total of 15 leadership competencies under three categories pertaining to intellectual, managerial, and emotional leadership. Fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) was implemented to examine the cause-and-effect relationships among the BIM leadership competencies and fuzzy analytic network process (ANP) was performed to weigh those competencies. Findings show that the intellectual competencies act as the cause group, while managerial and emotional competencies are the effect groups. Moreover, the involving leadership is found to be the more suitable leadership style for BIM professionals, given the current capability and maturity levels of BIM implementation, in order to deal with the required changes throughout the BIM implementation process. This study contributes to the existing body of knowledge in the BIM domain to examine the associated leadership competencies by using the multi-criteria decision-making (MCDM) technique. The results of this research show the relative importance of criteria and sub-criteria, which contributes to further improvement of BIM leadership.
