The modular construction technique is the one key technology that can substantially advance the competitiveness of the construction industry. However, the industry is having difficulty creating an optimum environment for broader and more effective use of modularization due to one key barrier: implementing a modular construction technique, that is, shipping modules from the fabrication shop to the build site. Multiple issues are potentially challenging to overcome, such as module size and center of gravity, rigging, tie-down, site access, site congestion, and transportation regulations, as well as the availability of local heavy lift equipment. The researchers propose to implement drones as …

Accelerated bridge construction (ABC) is an innovative construction technique used to accelerate the construction of new bridges, as well as the renovation/replacement of existing bridges. Due to the benefits offered by ABC, transportation authorities have a higher preference in executing an accelerated approach over conventional bridge construction. The execution of an accelerated approach has differences when compared to the conventional approach, and it is important to identify such differences for the successful implementation of ABC projects. However, there have been no studies to identify such execution differences. Therefore, this study was conducted to identify execution plan differences relevant to ABC. …

Modularization is a well-known construction technique where sections of the job are moved from on-site to a fabrication shop. Previously, the researchers identified the 21 most influential Critical Success Factors (CSFs) for successful modularization and quantified the degree of each CSF’s accomplishment by conducting a survey with 19 subject matter experts, and a case study with three modular projects. Through this methodology, the findings relied on the experience of experts. However, still missing from the understanding of modularization CSFs is a validation of the current degree of each CSF’s accomplishment by examining actual modular projects using a sufficient number of …
