Hello Sir,
eQuest does not have the capability to directly model thermal bridges. The typical methodology is to calculate the effective U-value of the insulation/thermal bridge layer when building your layers for the construction.  BC Hydro has published significant research on building  envelope thermal bridging. See the lower portion of the webpage:

Dear building simulation colleagues,
I would very much appreciate any insights or work around to simulate envelope thermal bridges in e-quest.
