One notable capability of social insect colonies that has traditionally inspired distributed robot systems is their construction activity. In this paper, I describe a system of simple, identical, autonomous robots able to build two-dimensional structures of arbitrary design by rearranging blocks of building material into desired shapes. Structure design is specified compactly as a high-level ge...

Rework adversely impacts the performance of building projects. In this study, data were analyzed from 788 construction incidents in 40 Spanish building projects to determine the influence of project and managerial characteristics on rework costs. Finally, regression analysis was used to understand the relationship between the contributing factors, and to determine a model for rework prediction....

SUMMARY: Construction projects involve a large number of both direct stakeholders (clients, professional teams, contractors, etc.) and indirect stakeholders (local authorities, residents, workers, etc.). Current methods of communicating building design information can lead to several types of difficulties (e.g. incomplete understanding of the planned construction, functional inefficiencies, ina...

Environmental pollution is considered to be one of the main concerns in the construction industry. Environmental pollution has become a major challenge to construction projects due to the huge amount of pollution caused by construction projects. There are different types of environmental impact indicators, such as the greenhouse gas (GHG) footprint, eutrophication potential (EP), acidification ...

In order to enhance experience management for engineers participating in construction projects, it is helpful to provide engineers the experience exchanging and sharing platform to understand important issues form the previous executed projects during the construction. The proposed experience maps help engineers better to illustrate what they have previous earned experience to “real-life” probl...

This paper describes a demonstration system for visualisation of processes found in construction schedules of large-scale building projects. It was driven by plans to develop a new airport terminal building. The building model was virtualised and users were able to “step through” the various stages of its virtual construction. The system operates within a large screen VR theatre and allows seve...

construction industry consists of several phases in which a variety of stakeholders are involved. as construction projects are becoming larger, more complex and more diverse, the design phase has been more important factor for the success of projects than ever before. however, it is considered that most of design work occurred in actual design process is intangible. such recognition makes the d...

Building construction projects appear to have higher accident rates. Contractors procure workers’ compensation insurance (WCI) to transfer these risks to insurance companies. The commitment of insurers under WCI is extremely broad; there are no exclusions and ceilings on their liabilities. They must quote adequate premiums to cover future risks. Yet, the prices should be low enough to penetrate...

In this paper, supply policy and procurement of shared resources in some kinds of concurrent construction projects are investigated. This could be oriented to the problems of holding construction companies who involve in different projects concurrently and they have to supply limited resources to several projects as well as prevent delays to any project. Limits on transportation vehicles and st...
