What are Back Charges?

A lien waiver is a legal document used in the construction industry that is often exchanged between parties involved in a construction project. This waiver essentially absolves or "waives" the claimant's (typically a project participant like a contractor, subcontractor, or supplier) right to impose a lien on the property for the amount they have been paid. It's often used upon payment to ensure that the payer is protected from double payment or any encumbrances on the property related to payment disputes. There are four general types of lien waivers: conditional and unconditional, each of which can be used for progress or final payment. Each type has its own legal implications, so it's important to understand them fully before signing.

Bottom-of-Chain or Low-Tier in the construction industry refers to the lowest level of subcontractors or suppliers involved in a construction project. They are at the end of the construction chain, typically providing specific services or materials as subcontracted by higher-tier companies. These can include specialized tasks like electrical work, plumbing, landscaping, or supply of construction materials. Their work is crucial as they lay the foundation for more complex tasks to be executed by upper-tier contractors. They are also bound by the contracts in place, like other members of the chain, although directly managed by mid-tier subcontractors instead of the main contractor.

Progress Billing is a method commonly used in the construction industry, where billing for a project is done at different stages as it progresses, rather than asking for full payment upfront or at the completion of the project. This type of billing is beneficial both for constructors and clients. For constructors, it helps maintain the cash flow required for the ongoing expense of materials and labor. For clients, it provides assurance that they are paying for the work only as it is being completed and allows them to budget effectively. Each invoice is usually based on the percentage of work completed, thus it is also known as percentage-of-completion billing method. Proper documentation, like progress reports or photos of the construction site, often accompany these invoices as a proof of progress.
