Project is located in Sioux Falls, SD. Was delayed for 1 year+ at no fault of our own (subcontractor), and is now finally substantially complete (as of 4/13/18). Contract is paid to date with exception of balance pay app for $25K, plus $12K retention. We have submitted a claim for delay damages that total $11K which GC refuses. Our question is: are we able to enforce any lien rights for our claim or are the lien rights reserved for the contract price ONLY?
