About the Workshop
The
Purpose of the workshop is to identify
inter-operability requirements and priorities for enabling the
development of standards for seamless jobsite data exchange for
the construction industry.
Background and Motivation:
The construction industry has indicated that knowledge of the status of a
construction project is one of the most challenging problems faced by project
management and jobsite personnel [1, 2]. Although construction measurement and
sensing technologies and project information management software (PIMS) – such
as scheduling and estimating software – have advanced considerably in the past
20 years, accurate and up-to-date knowledge of the current status of a
construction project remains elusive.
New CAD technology is attempting to bridge the gap between scheduling and
traditional CAD software thereby producing a new class of software technology
known as 4D CAD. 4D CAD allows “visualization of the facility design and its
changes over time and allows computer-based analysis of constructibility, cost,
productivity, and other project performance variables dependent on an
integrated analysis of time and space” [3].
However, both 4D CAD and other PIMS need to be supplied with updates from the
jobsite about the state of the various construction activities, and at present
these systems rely primarily on workers who manually enter up-to-date
information. One of construction automation’s premises is to introduce advanced
measurement and sensing technologies onto the jobsite in order to automate the
updating process. Ubiquitous sensing with real-time construction process
monitoring and control are the prerequisites for creating the intelligent
jobsite [5].
This workshop will focus on the data exchange issues involved in seamlessly
integrating future and existing measurement and sensing technologies (such as
LADAR, GPS, RFID, total stations, temperature sensors, strain sensors, and
etc.) with construction software and other hardware in order to improve
productivity, quality, and safety, and how to prepare for future sensing and
automation challenges, such as fully-automated machinery on the jobsite.
Who should attend?
Construction measurement and sensing instrument manufacturers, construction
software developers (e.g., scheduling, CAD, etc.), construction industry
stakeholders, construction machinery manufacturers, and construction automation
and sensing researchers/specialists.
Desired Workshop Outcomes:
1. Identify a prioritized working list of measurement and sensing
technologies
2. Identify requirements for and barriers to sensor data exchange in
construction
3. Identify and plan the steps required to establish raw sensor data-exchange
standards
4. Identify future research directions
