What is a Notice of Commencement (NOC)?
A Notice of Commencement (NOI) is a legal document filed by general contractors (GCs) to formally declare the start of a construction project. In addition to establishing an official record of when construction began, it also provides essential information about the project—property details, project scope, contact information for key project stakeholders, etc. In some states, it may be referred to as a Notice of Project Commencement, an Affidavit of Commencement, or a Notice of Contract.Â
For subcontractors, NOCs are important because they determine when you need to file paperwork to protect your lien (and thereby, payment) rights. Once the owner or GC files an NOC, it often changes the deadlines for when you must submit preliminary notices and mechanics� liens. These documents contain vital project information, including:
- legal property descriptions,
- owner details,
- GC information, and
- surety data.
In most states where NOCs are required, they must be posted at the job site and recorded with the county clerk’s office. Subcontractors should be aware that failing to respond properly to an NOC could result in losing their right ot file a lien if a payment issue arises.
Staying informed about documentation like NOCs is crucial for securing payment on construction projects.

What is a G702?
A G702 is a document form used in the construction industry known as the Application and Certificate for Payment. It is issued by the American Institute of Architects (AIA) and is used by contractors to apply for payment for the work completed and materials supplied on a project. It details the contractor's progress on the project, summarizing the total project to date, change orders, previous payments, and the current payment due. The form needs to be signed by the contractor, the architect, and the owner, certifying that the work has been completed and payment is deserved.
What are Payment Applications (Pay Apps)?
A payment application (or pay app) is a comprehensive collection of documents that construction contractors submit to request progress payments throughout a project. Rather than just a simple invoice, payment applications include multiple forms and supporting documentation that prove what work was completed, which materials were used, and what payment is due. The typical pay app package includes:Â
- an application for payment form,Â
- a continuation sheet with schedule of values details,Â
- lien waivers, andÂ
- often backup documents like material receipts and payroll reports.Â
Payment applications are submitted on predetermined schedules—whether monthly, at project milestones, or when specific percentages of work are completed—and serve as the primary billing mechanism for longer, higher-budget construction projects.
For subcontractors, mastering payment applications is critical because they directly impact cash flow and project profitability. The process involves coordinating between accounting teams, project managers, and vendors to gather all required documentation before submission deadlines. Common mistakes—like using incorrect forms, missing documentation, math errors, or late submissions—can delay payments and disrupt cash flow. Many GCs have their own custom forms and specific requirements, making attention to contract details essential.Â

What are Liabilities?
In the construction industry, liabilities refer to the financial obligations the company owes to external entities, often as a result of past transactions or activities. These include payments to suppliers, wages to employees, loans from financial institutions, taxes to government bodies, etc. Additionally, in this industry, liabilities may also include future commitments to complete ongoing construction projects within a stipulated time frame and specific budget. Unfulfilled such obligations may lead to penalties or legal action, enhancing the liability further. Also significant are potential liabilities such as compensation for any work-related accidents or damages occurring at construction sites. Hence, managing liabilities effectively is vital for the financial health and reputation of any construction firm.
