Abstract: In construction, failure of design professionals to consider how a builder will implement the
design can result in scheduling problems, cost escalation, delays and disputes during the construction process.
The integration of construction knowledge and experience during planning and design is termed here as
constructability. Though many design professionals in the Netherlands may ...

Abstract: Risk management in construction encompasses four main phases; risk identification,
quantification, mitigation and control. Risk identification has been recognized as the most crucial phase of a
successful risk management program. This paper briefly describes a model, designed to automate the risk
identification process. The model facilitates the development of an electronic checklist of ...

Abstract: Construction management education, like most education and indeed, most things, is changing
rapidly. There is a move towards student centred learning which is intended to allow students to gain knowledge
at their own pace and develop transferable skills during the course of their education.
In Construction Project control is an essential task of ...

Abstract: In this paper an approach for the throughput evaluation of the construction manufacturing
systems is presented. The throughput is evaluated with a heap-based algorithm for the Petri nets model of the
construction systems. The Petri nets model is a stochastic one, and the firing rate of the transitions are calculated
with Markov chains ...

Abstract: More than 200 capital facility projects from across the U.S. have been assessed on the issue of technology usage at the work function level and overall project cost and schedule success. Work functions
(WFs) that may leverage project cost and schedule performance were identified. The analyses suggested that degrees of technology ...

Abstract: This paper will propose to investigate results obtained from automated measuring process control of temperature in cement fabrication with the simulation modeling by probability distribution functions and conducted at yield goodness of fit results.
The simulations results enable the comparison with the data obtained by automated real-time project process data which ...

Abstract: The conceptual estimate plays an essential role in project feasibility study. In practice, it is performed based on
estimators experiences. However, due to the inaccuracy of cost estimate, budgeting and cost control are planned
inefficiently. In order to increase the estimate accuracy, this study employed the Evolutionary Fuzzy Neural
Inference Model (EFNIM) to ...

Abstract: The profit of Construction Industry has been tremendously reduced for recent years in Taiwan. In
order to survive in this difficult environment, Management becomes the key issue to achieve companys target.
We need a powerful tool that can help us to handle complicate process such as estimation, bidding, purchasing
and site-management in the ...

Abstract: Information technology (IT) that is achieving astounding progress has been applied to rationalize
construction project management and is expanding the potential for the automation and use of robots in
construction work. But the development of IT based systems has often resulted in cases where it is difficult for
multiple systems to share electronic ...

Abstract: The Building and Fire Research Laboratory of the National Institute of
Standards and Technology, in cooperation with the Fully Integrated and Automated
Technology (FIATECH) consortium, sponsored a workshop on data exchange standards at
the construction job site in May 2003. The purpose of the workshop was to investigate the
problem of exchanging sensor data ...

Abstract: Enterprise Resource Planning (ERP) is the latest high-end solution information technology has
lent to business application. Enterprise resource planning systems are highly complex information systems. The
implementation of these systems is a difficult and high cost proposition that places tremendous demands on
corporate time and resources. Many ERP implementations have been classified as ...

Abstract: As a result of the rapid advance of information technology (IT) and development of CALS/EC in
recent years, the MLIT (Ministry of Land, Infrastructure and Transport) and other organizations that order public
works projects now deliver the results of survey and design work and completed work drawings as electronic
data and can now ...

Abstract: Reliable and timely information describing up-to-date performance is a prerequisite for effective
management of construction. Existing methods for on-site data collection are labor-intensive, subjective, and the
data are frequently available only after activities have been completed. Monitoring of the main lifting equipment
on construction sites can provide real-time, low-cost and objective data for ...

Abstract: Building projects which are build in the Dutch Industrial, Flexible and Sustainable (IFD) Building
programme usually focus on the design of the project and the application of prefabricated parts. Though this is
indeed an important factor in IFD-projects, the paper supports the idea that successful IFD projects rely on three
aspects: An industrialised ...

Abstract: Over the years, the art of block laying has been an important factor in building construction.
Different cultures and construction experts have developed various styles, giving values to block laying.
The major problem in block laying has been traced to the poor productivity of the masons. This has really
hindered the construction time ...
