Portable Computer-Based Systems for Creation of as-Built Drawings

摘要

Proof-of-concept has been established for a cost-effective, portable, computer-based system for the acquisition and processing of data needed to create, on-site if desired, as-built drawings of facilities. The system addresses the three major problems associated with current practice: (1) lack of reliability due to the manual aspects of the measurement and information transfer process; (2) high cost in terms of manpower for initial and repeat surveys; and (3) delay between the measurement process and the production of as-built drawings. The system enhances reliability by electronically transferring measurement information to the drawing database. Immediate checks on consistency and accuracy are possible because the shapes emerging from the data are displayed to the field personnel as soon as the data is taken. Cost will be reduced. Delays in obtaining final drawings will be virtually eliminated, since drawings can be obtained as soon as measurements are made.
