32. NIST Construction Automation Program Report No. 4: Non-Intrusive Scanning Technology for Construction Status Determination
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6457
Published: 1/1/2000
Authors: Geraldine S Cheok, Robert R Lipman, Christoph Johann Witzgall, Javier Bernal, William C Stone
Abstract: Approximately 2 % of all construction work must be devoted to manually intensive quality control and tracking of work completion, including operations involving earthmoving and bulk materials handling. Any technology that can reduce this burden and ...
