Foundation crack found under a brand new slab in Phoenix last Tuesday

I poured a 40 yard slab for a strip mall last week and five days later the GC points out a hairline fracture running from a control joint to the edge. Turns out the compacted fill had a soft spot right under that section about 8 inches deep. I had to saw cut a 4 foot square out and repour it with a high early mix to keep the schedule on track. Has anyone else dealt with subgrade issues showing up after the pour finished?

Read somewhere that a lot of contractors actually pad their quotes because they expect you to haggle. Ever try countering their price or getting a second bid?
