As a result, musculoskeletal disorders are common issues in construction and result in costly delays and disability claims. Though there is recent research investigating the epidemiology and causal factors for musculoskeletal injury, the construction industry has not fully embraced this as part of its safety practices. This study presents state-of-the-art ergonomic techniques, Canadian ergonomic legislation, and work-related musculoskeletal disorder (WRMSD) lost-time claims (LTC) statistics to show the resultant economic (cash and productivity) losses and adverse social (occupational health and safety) impact of WRMSDs resulting from current practice and legislation. The potential short-and long-term productivity and cost merits of incorporating ergonomic assessments for construction tasks are presented.

This paper deals with an approach to provide better information to derive relevant and effective risk measures for specific risks. The approach

In devising strategies to manage and minimize these impacts, gaining an in-depth understanding about timing and spatial extents of them is crucial. However, in practice gaining such understanding is difficult due to the complex and varying nature of the impacts. To support project planners with understanding a highway construction project's impacts upfront, we developed a 4D modeling method that visualizes the most important attributes of the impacts on the public, namely their spatial extents and their progression over time. By applying the method to support a Dutch highway expansion project, we show that, compared to 2D methods, the proposed 4D modeling method provides an integral perspective of the spatial changes of the project impacts over time that allows for the evaluation of various scenarios with relative ease.

It describes a knowledge-based system designed for this purpose. A knowledge acquisition exercise was undertaken to determine the tasks of project managers and the information necessary for and used by these tasks. This information was organised into a knowledge base

Designers need to consider not only building performance, but also production plan needs. This requires a well-structured Building Information Model (BIM) to support the manufacturing needs for design and drafting. BIM, in combination with CAD tools such as AutoCAD and ArchiCAD, can be used for this purpose. These, however, are not sufficient to support the level of detail needed for the manufacturing process. The proposed research establishes a methodology for the automation of design and drafting for the building manufacturing of residential facilities based on the platform construction framing method. The proposed methodology has been incorporated into a computer model called MCMPro, which was developed using Visual Basic for Applications (VBA) as an add-on to a CAD model. MCMPro incorporates BIM technology based on CAD parametric modelling and manufacturing requirements in a 3D-model, in order to generate sets of shop and fabrication drawings.

Modular building is the highest degree of industrialization of the building construction process. In this context, the manufacturing of buildings in a factory and their shipment in modules to the site, demands a new approach to scheduling and resource use. Because of their large geometric volumes, handling the modules especially on construction sites can be extremely challenging. As a result, 3D visualization tools are critical for precise planning since they allow one to resolve beforehand any spatial constraint such as collisions with existing obstructions and lifting paths feasibility. This paper addresses the two most important aspects of modular construction: 1) shop manufacturing and 2) on-site assembly. In this respect this contribution describes a methodology which integrates simulation models and post-simulation 3D-Visualization. The integration of these tools provides a framework allowing to gain a detailed insight into the dynamics of the manufacturing and assembly processes and also to gauge the risks related to the work-space and interference of modules with the surrounding obstacles. The proposed methodology is validated by a case study that involves the construction of five (5) student dormitories for Muhlenberg College, Pennsylvania, USA. The five (5) buildings are each 3-storeies consist of 18-modules, totaling 92-modules for all five buildings. The 92-modules were manufactured at Kullman (a modular manufacturer in New Jersey, USA).

The additional factors cover issues related to design, boring process and ground conditions encountered in Dutch soils. The model is intended to support risk decision making, more specifically, to derive specific risk measures to control excessive ground deformation on a case-by-case basis.
