CONSIAT: Construction Integration and Automation Technologies


Objective:

To develop enabling measurement science, methods, protocols, and knowledge to improve construction productivity with the integration of information, communication, sensing and automation technologies.

Problem:

During the past 40 years, construction productivity has declined while manufacturing and other industries have achieved significant
improvements in productivity and quality with the application and integration of information and automation technologies. As measured
by constant contract dollars of new construction work per field work hour, labor productivity in the construction industry has trended
downward at an average compound rate of -0.6 % per year . This is particularly alarming when compared to the increasing labor
productivity in all non-farm industries, which has trended upward at an average compound rate of 1.8 % per year. The construction
industry seriously lags other industries in developing labor saving ideas and in finding ways to substitute equipment for labor. [1]

The construction industry has repeatedly identified the importance of advancements in information, communication and automation technologies to achieve fully-integrated and automated project delivery. Unfortunately, research in these areas has focused on isolated problems, independent of how integration within and across enterprises and combinations of these new technologies can enable major productivity improvements. The FIATECH Capital Projects Technology Roadmap , a cooperative effort of associations, consortia, government agencies, and industry, recognizes that the construction industry greatly lags other sectors, such as manufacturing, in exploiting these technological advances. The Construction Industry Institute’s Strategic Plan emphasizes the evaluation of these new technologies that may have application to the industry and the development of methods to use these technologies to overcome challenges associated with the globalization of the construction industry.

The construction industry is making progress in developing common practices for the creation, capture, delivery and the use of basic, digital building information, e.g., 3D models and scanned images for clash detection, object recognition and space management, but the interoperability and integration with construction contractors’ project control and job site automation systems is extremely limited. Due to the lack of proven methods for developing, testing and deploying robust data capture and exchange protocols and the lack of methods and resources for semantic harmonization across intersecting information domains, early efforts to solve these problems have had minimal success. Additionally, the technology developments aimed at bridging the use of building design data, construction job site data and geospatial data are proceeding in a piecemeal fashion. It is difficult to determine how the work from these communities can be put into use in real-world construction projects and to meet the needs of public safety officials and first response teams.

Why is the problem hard to solve? The problem is hard to solve because the methods and measurement science for applying and integrating these technologies are unproven, evolving and in many cases, missing. The complexity of construction projects, the ever changing mix of companies participating in each project and the vast range of work processes for which interoperable automation solutions do not exist make this problem overwhelming for the vast majority of the engineering and construction contractors. Although large engineering companies have succeeded in applying some of these technologies for specific disciplines, particularly in design, the use of these technologies to achieve productivity improvements across the participating organizations and at the construction site has eluded the industry. There are no established measurement methods and metrics by which the technology developments can be assessed for their capability, compatibility, and productivity improvement potential and by which software implementations can be assessed for their ability to interoperate. Further, the measurement science and methods for establishing data model congruency and for developing consistent taxonomies for achieving construction integration and interoperability do not exist.

How is it solved today and by whom? Some construction industry organizations are examining how to change the industry work practices to use aspects of these new technologies. Some are promoting the development of information exchange standards, and others are participating in projects to demonstrate the value of individual new technologies. Research in these areas is focused on isolated problems, independent of how integration across enterprises and in combination with these new technologies can enable major productivity improvements. These efforts are not investigating or developing the measurement science needed to deliver the solution enabling tools to improve construction productivity.

Approach:

The CONSIAT program will develop enabling measurement science, methods, protocols and knowledge to:

• measure construction productivity at three levels: (1) task; (2) project; and (3) industry,
• integrate construction site metrology data and other field information with project control systems or other processes requesting the information (e.g., job site machinery and workers),
• assess and deliver data model congruency,
• integrate project, product and facility information across design, fabrication and construction,
• integrate diverse information systems,
• produce conformance test suites and test scripts for evaluating construction project data standards and software implementations of these standards,

and by establishing testbeds to evaluate and refine next generation technologies, data representation and exchange protocols and the integration of the technologies for improving construction productivity. BFRL will work in close partnership with CII and the FIATECH Consortium to maximize the relevancy of the projects and the leveraging of resources, and to minimize the time to end-user implementation of the program results.

In FY2008, the CONSIAT program will develop and demonstrate tools and protocols for using 3D imaging technology, geospatial data and building information modeling for progress tracking and discrepancy identification. CONSIAT will establish the Virtual Project Data Integration Testbed and will evaluate the initial set of project data integration scenarios and specifications. CONSIAT will initiate work with research leaders, the National Research Council, CII, FIATECH and other industry initiatives on ways to improve the productivity and competitiveness of the U.S. construction industry.

In FY2009, CONSIAT will develop experimental software for demonstrating information access and exchange services in a Service-Oriented Architecture for use in construction control scenarios. CONSIAT will develop methods and metrics for validating construction project data interchange specifications and for producing conformance test suites for construction project data standards. In partnership with the National Research Council and industry, CONSIAT will drive the development of a national research agenda for advancing productivity and ICAST (information, communication, automation and sensing technologies) capabilities in the construction industry.

In FY2010, CONSIAT complete the trial uses of a new tool for measuring construction productivity at the project and industry levels and will make the tool available for industry use. CONSIAT will conduct site tests of construction control and automation protocols using 3D imaging, building information models and information access services. CONSIAT will develop and demonstrate the use of a real-time control system adapted to construction processes. The resulting methods and specifications will be submitted to appropriate organizations for standardization.
