The Department of Energy (DOE) has given the Spallation Neutron Source (SNS) project approval to begin Title I design of the proposed facility to be built at Oak Ridge National Laboratory (ORNL) and construction is scheduled to commence in EyOl . The SNS initially will consist of an accelerator system capable of delivering an -0.5 microsecond pulse of 1 GeV protons, at a 60 Hz frequency, with 1...

In the United States, there is currently significant growth in the construction of healthcare facilities. This healthcare construction boom is driven by multiple factors including population shifts within the U.S.; aging facilities which no longer meet modern operational practices and efficiencies; and significant shifts in building code requirements. The last major healthcare construction boom...

Currently, design and construction documents submitted to the governing body for permitting are checked manually against a continuously changing and increasingly complex set of building codes. The complexity and changing nature of codes leads to delays in both the design and construction processes. The designer must assess which codes are applicable to a given project as well as sort through po...

The U.S. Army Corps of Engineers has developed a tool called the Modular Design System (MDS) to assist design professionals in the processes of planning, design, and construction document preparation for repetitive facility types. The use of early versions of MDS has demonstrated a reduction in time by nearly two-thirds typically required to design and award a construction contract. Initially d...

Collaborative applications provide a group of users with the facility to communicate and share data in a coordinate way. In this paper we propose a pattern system to design the basic aspects of data sharing, communication, and coordination for collaborative applications. These patterns are useful for the design and development of collaborative applications as well as for the development of plat...

Collaborative applications provide a group of users with the facility to communicate and share data in a coordinated way. Building collaborative applications is still a complex task. In this paper we propose a pattern system to design basic aspects of data sharing, communication, and coordination for collaborative applications. These patterns are useful for the design and development of collabo...
