Abstract:
1. A method for providing real-time visibility on a construction project, said method comprising steps of: attaching a low frequency, ultra low power, two-way transceiver radio tag to each item of construction material to be used in the construction project, said radio tag comprising: storing, in the data storage device of the radio tag, data relating to said construction material; networking the radio tags; reading the identification data from the transceiver of at least one of the radio tags, wherein reading the identification data comprises interrogating said at least one radio tag with radio frequency interrogation signals at a low radio frequency not exceeding 450 kilohertz via said tag antenna; and during construction, cross-checking actual placement of the construction material with a specification to determine if the placement is correct, wherein the cross-checking is performed by the radio tags attached to the construction material.
