Time is a basic parameter connected to a construction schedule.
Considering the curing quality of concrete or spreading material on a field, time may also have an impact on construction quality.
Time is automatically captured in the RFID system when context changes take place.
The location of users and materials can influence the entire construction process.
To track the location using RFID, many systems use RFID-gates.
When materials pass through the gates, the location parameters of the materials are changed.
To identify the location in detail or in person with a material inspection, a specific tag can be attached to the location.
In this case, the locations are detected manually by a mobile reader, such as a PDA reader.
