Effective coordination among supply chain entities, particularly factory production, transportation, and onsite assembly, is critical in offsite construction as a means of mitigating the risk of schedule delays. Offsite construction companies thus tend to develop master schedules that consider not only production capacities and resources in the fac...

This paper presents the results of an experimental study on the short-term mechanical performance of timber screw connections comprising two types of fasteners suitable for a novel panelized roof design process. Thirty-seven specimens of five different connection configurations were tested under quasi-static monotonic loading. The main objective of...

In off-site construction, finding good synchronization between the factory and the construction site is critically important. However, in practice, on- and off-site operations are typically scheduled separately, without considering their performance at the project level. For the planning of logistics operations that bridge a factory and sites, this...

Panelized construction is gaining popularity within the industry as a primary construction method. In panelized construction, a building model is subdivided into subassemblies such as wall panels, floor panels, and volumetric roof modules for the purpose of manufacturing. Although this construction method is faster and offers many advantages compar...

Panelized fabrication of light-frame wood building has higher productivity than the traditional stick-built method. However, the roof production process is not very efficient due to the structural system and construction method. A new holistic approach for the roof structure is developed to improve the productivity of the panelized construction pro...

Material management is a critical aspect in construction. Poor management of construction material can lead to budget overrun and schedule delays, considering the lead time required for ordering material. Offsite construction is a trending paradigm in construction for the benefits of reduced construction material waste. However, in offsite construc...

Off-site construction uses production lines to produce building components in a controlled factory setting. By shifting construction activities to an off-site environment, many manufacturing principles can be employed, including the use of simulation to predict production's performance and the impact of different labour arrangements. Typically, eac...

Off-site construction and building information model (BIM) technology bring benefits to the construction industry in many respects, such as reduced material waste, and lead to solutions towards sustainable construction. Nevertheless, despite the uptake of off-site construction methods and BIM, massive construction waste in terms of sheathing materi...

The construction industry is shifting from traditional on-site (stick-built) to an off-site construction paradigm in which building systems are engineered, assembled in a controlled environment and shipped to site for installation. Despite the potential benefits associated with this shift, there is still a knowledge gap concerning the impact of usi...

Offsite construction methods have been promoted and recognized globally as advanced construction techniques. Panelization, a two-dimensional form of offsite construction has brought about many benefits including lower transportation requirements and design flexibilities. In North America, the panelized construction technique has become popular part...

Panelized construction has proven to be a promising construction method due to its use of an offsite manufacturing environment, which provides a higher quality product with fewer site disruptions and a shorter construction cycle. This study focuses on developing an optimization model for improving the utilization of raw stock during the automatic c...

Panelized construction, an emerging offsite construction method, is garnering increasing attention globally particularly for wood-frame wall panels as an advanced construction technology. Although utilizing this advanced construction method can greatly improve the working environment and productivity, the conventional mentality in construction, whi...

Modular construction and panelized construction have been promoted and recognized globally as advanced construction techniques. Not only have these construction methods been utilized in the oil and gas industry, but they have also successfully been introduced into the residential construction industry. In North America, the panelized construction t...

Logistics operations in panelized construction are vital daily tasks that connect the panel manufacturing facility to the job site. Although logistics operations are both important and prevalent in panelized construction, the cost of logistics has yet to be fully understood by either industry or academia due to the complicated relationship between...

Over the past few years, the interest towards off-site construction as part of project delivery for residential and commercial buildings has increased dramatically. In this regard, buildings are decomposed into panels that are manufactured using assembly lines smilar to what was developped to the automotive industry. However, because these serial p...

Panelization, a form of off-site construction with origins in the manufacturing industry, has emerged as a popular, more efficient approach to constructing residential projects. This approach transfers some of the construction activities traditionally carried out on site into factory production tasks, and divides construction management into factor...

In recent years off-site construction has become popular in North America due to the superior quality of the product, improved productivity, and reduced environmental impact. The panelized construction approach is one of the most readily utilized off-site construction methods. In a wood-frame panelized construction plant, wall panels are customized...
