What is a Lien Waiver?

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.

Backlog

What is a Backlog?

A Backlog in the construction industry refers to the accumulation of work orders or tasks that are yet to be completed. It is often utilized as an indicator of the volume of work that needs to be addressed. Within a construction context, a backlog could include pending blueprints to approve, inspections to perform, or specific construction tasks to complete. It is crucial for project managers to monitor and manage the backlog because it can directly impact project timelines, productivity, and ultimately, profitability. A high backlog suggests a heavy workload and the potential for delay. A low backlog may indicate that there is not enough work to keep the crew busy. Therefore, balancing the backlog is key in efficient project administration.

Bottom-of-Chain, or Low-Tier

What is Bottom-of-Chain or Low-Tier?

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.

Allowance

What is an Allowance?

In construction, an allowance is a predetermined dollar amount included in a contract to cover materials, fixtures, or finishes that haven’t yet been selected. Allowances are typically used for flooring, lighting fixtures, plumbing fixtures, appliances, or other finish materials (things that contribute to the project’s aesthetic) where the owner may want flexibility to make selections as the project evolves.

Here’s how allowances work: When contractors bid on a project, they’ll include specific allowance amounts (e.g., $5,000 flooring allowance). Once construction begins and the owner chooses actual materials, the costs are reconciled against the allowance. If the materials cost less, they receive a credit. If more, the owner pays the difference via a change order.
