What is an Estimate?

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.

An office in the construction industry refers to a space, whether portable or fixed, utilized for administrative tasks such as managing construction plans, processing permits, overseeing contracts, and coordinating construction activities. It may be onsite or offsite, functioning as the hub for project management. Onsite offices, often seen in portable cabins or trailers, serve as the command center monitoring real-time construction progression. They store important documents, house communication devices, and serve as a meeting spot for employees and visiting clients. Offsite offices, on the other hand, handle larger administrative tasks such as project bidding, procurement, and capital management. Moreover, it acts as a central contact point for multiple construction sites. Both types of offices play a pivotal role in ensuring a smooth, sustainable, and efficient execution of construction projects.

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.
