What is AIA® billing?

AIA® billing is a standardized payment application process for construction projects. Developed by the American Institute of Architects (AIA®), it uses specific forms—primarily the G-702® Application and Certificate for Payment and G-703® Continuation Sheet—to document and request progress payments throughout a project. These forms create a uniform system for contractors that shows exactly what work has been completed, what materials have been stored, and what payment is due during each billing period. They also require detailed information about contract values, change orders, and retainage amounts. AIA® has become the industry standard, especially for larger commercial projects and government contracts.

For subcontractors, understanding AIA® billing is essential since most large general contractors (GCs) require these forms or customized versions of them. While AIA® billing can initially seem complex, it provides important benefits like reducing payment disputes, creating clear documentation of work progress, and often resulting in faster payments. Mastering AIA® billing opens doors to working with larger GCs and bidding on more substantial projects. That’s why we created this comprehensive guide, filled with detailed information on completing AIA® billing forms and managing the payment application process.

Siteline simplifies the AIA® billing process by automating form creation and submission. Our system currently maintains 15,000 custom billing forms from more than 10,000 GCs, enabling subcontractors to generate perfect pay apps in minutes for fewer delays and faster, more predictable payments.

Conditional Lien Waiver

What is a Conditional Lien Waiver?

A Conditional Lien Waiver is a legal document used in the construction industry that states a contractor, subcontractor, or supplier will give up or waive their right to place a lien on a property, under the condition they receive their expected payment. This waiver serves as a protection mechanism for the party responsible for payment, ensuring that once the payment is made, no future lien could be placed on the property for the services or materials provided.

Mortgage

What is a Mortgage?

A mortgage, within the framework of the construction industry, is essentially a loan secured by a real property through the use of a mortgage note to evidence the existence of the loan and the encumbrance of that realty. This serves a crucial financial function during the building process as it allows homeowners or builders to purchase land or property without needing the full amount upfront. In most cases, a banking institution or lender offers the borrower a certain sum to buy a property, the borrower then repays this sum, typically monthly, with added interest, over a defined period. The mortgage ties the obligation of repayment to the property itself. Hence, when a mortgage loan is used for construction of a new property, the funds are dispersed to the borrower as work on the construction project proceeds. In the event that the borrower defaults on their mortgage payments, the lender has the right to take possession of the property, in a process known as foreclosure.

Quantity Survey

What is a Quantity Survey?

A quantity survey, also known as a bill of quantities (BOQ), in the construction industry is a detailed analysis and estimation of all parts, materials, and costs associated with a construction project. This process is carried out by a professional known as a quantity surveyor. The surveyor evaluates the quantities of materials needed, required labor, groundwork needed, and the overall time frame of the project. They also consider other variables to provide an accurate cost analysis, like the complexity of the project, the potential risks, and the market conditions.

The main purpose of a quantity survey is to:

  • Accurately estimate the cost of a construction project: By quantifying all the required materials and resources, the quantity survey helps contractors and clients estimate the total cost of the project accurately. For subcontractors specifically, quantity surveys are used to price out the cost of their portion of the work, ensuring they quote competitively while accounting for all the necessary materials and labor.
  • Facilitate bidding and tendering: The quantity survey provides a standardized format for subcontractors to prepare their bids based on the same information, ensuring fair competition during the tendering process.
  • Control project costs: During the construction phase, the quantity survey serves as a reference point for monitoring and controlling costs, as actual quantities used can (and should) be compared against estimated quantities.
  • Manage changes: If the original scope of work changes or varies, the quantity survey serves as a baseline for evaluating and negotiating the cost implications of those changes.

A quantity survey is essential for subcontractors to accurately estimate costs, plan resources, and manage project scope. While not directly integrated, solutions like Siteline allow subcontractors to leverage quantity survey data to streamline their billing processes.

  • Subcontractors can generate payment applications in Siteline that reflect completed work items and quantities from the survey, minimizing disputes.
  • Some clients use Siteline's billing and A/R reports to help quantity surveyors and estimators account for contractors with longer payment cycles. They can either increase bids for those contractors to offset delays or revise terms to penalize late payments.
  • Siteline also seamlessly tracks change orders, enabling subcontractors to easily update payment applications and lien waivers when project scope changes, keeping everything documented and billed accurately.

By bridging the gap between contracted scope and actual billing, Siteline enables subcontractors to focus on execution while ensuring prompt, accurate payments. Experience the power of efficient payment management tailored for subcontractors. Schedule a demo of Siteline today.
