Hi Ning,
Thank for your keep following up to support team. I also just found your draft PR below, it seem to be that the GMCS code is incorrect. Please checking well prior raise a new PR after solve the problem on budget exceeding.
For this project is change roof, right? So, the GMCS code should be ILMFS0803 (not ILMFS0802) (kindly try to check as I showed you this morning)
