I am not aware of any way for you to require someone to take a lie detector test for this type of incident.
If Travelers refuses to pay your claim, you can either pursue your property damage through your own auto insurance company if you have the type of coverage that will cover this type of claim or you can pursue a lawsuit against the construction company and try to prove your claim in court. Good luck with this matter.
