The situation is as follows: My company is both a manufacturer and subcontractor for custom cabinetry & woodwork projects. We were hired to produce a custom cabinetry/woodwork project around October 2019 or so for a NYC based Contractor who's client is also a NYC resident. We performed the manufacturing work in our shop and have completed the manufacturing portion of the project before the year's end. The only thing missing was a lighting detail in question that we sought to resolve and has since been left unresolved by the GC. We also attempted, several times, to find out from the GC when we could schedule a time to deliver and install the finished work. Our requests were essentially pushed off and ignored. Our contract for this project states that the remaining 50% of our balance is due on completion of delivery and install. Now, I realize contracts are contracts however, due to COVID-19 and considering it's now APRIL 2020, we have no way of delivering and installing the work because the building the client lives in has a total restriction on any and all non-essential construction work. The fact is, we've been more than reasonable and accommodating with this GC, their client and the work. The result has been a loss of income on this project. We have a long history with this contractor where we've done several projects on good faith without paperwork. Regardless of that, we sent the GC photos of the completed work per his request which he did nothing with. We then tried to negotiate with them where we proposed to A. waive the installation cost and B. requisition payment for manufacturing work completed in the shop. They got belligerent with us and called us "opportunistic" due to the viral pandemic sweeping the world and have the emails to prove it. Our goal isn't to stress anyone out, especially during a pandemic. Our goal is to be fairly compensated for work completed prior to what has happened - where they, as a general contractor - had a big part in causing us to have a loss of income. So with all that being said, my question is: Despite our contract with this GC, considering our loss of income and the Corona virus pandemic - do we have a right to file a mechanics lien on this project?
