Good morning, This is Soo from Exbon Development Inc. I have a question in regards to how to file a payment claim to one of subcontractors which is not corresponding their labor/material work despite their scope of work. We have a subcontractor which was executed subcontract agreement for CA state public work project. This sub was irresponsible to perform their work, did not correspond with us and unsuccessfully uncompleted their work. Most likely they vanished at site. Due to their incomplete performance, we had to hire another subcontractor to cover their work and process material / equipment costs. Such costs are exceeded their contract amount although we back charged in their contract amount. Therefore, we would like to file a payment claim to them to collect the owning monies. Is there any effective claim or lien to subcontractor? If so, how are the procedures and how are they effective? Please inform me in detailed information. My email address is soo.chae@exbon.com. Please respond my question promptly. Thank you,
