We supply solids removal equipment to Contractors and Subcontractors for large municipal and private water projects. Our Agreements include startup and commissioning services as part of the agreement. During the construction of the facility, we may deliver the physical equipment in March and not be back to perform startup/commissioning until November, eight months after the equipment was delivered. In states that require notices and lien documents be filed within an allotted number of days after delivery how does the delay of services play into the timing. Example: we delivered equipment to a facility in KY in October of 2018. The Contractor held 5% retainage. In June 2019, we performed the startup, commissioned the equipment, and invoiced for the startup. We received notice in July that the Contractor filed for bankruptcy.
