We present the results of a 5GHz survey with the Very Large Array (VLA) and the expanded VLA, designed to search for short-lived (<~1day) transients and to characterize the variability of radio sources at milli-Jansky levels. A total sky area of 2.66deg^2^, spread over 141 fields at low Galactic latitudes (b~6-8{deg}), was observed 16 times with a cadence that was chosen to sample timescales of days, months, and years. Most of the data were reduced, analyzed, and searched for transients in near real-time. Interesting candidates were followed up using visible light telescopes (typical delays of 1-2hr) and the X-ray Telescope on board the Swift satellite. The final processing of the data revealed a single possible transient with a peak flux density of f_{nu}_~2.4mJy. Furthermore, we use the data to measure the source variability on timescales of days to years, and we present the variability structure function of 5GHz sources.
