This snag list, as generated by the Contractor, is known as the punch list.

According to the General Conditions ( AIA A201 Section 9.8.2), the Contractor prepares and submits to the architect a comprehensive list of items to be completed or corrected. In most contracts, the general conditions of the contract for construction require the contractor, when they believe it to be so, to declare the construction project to have reached "substantial completion" and to request a "pre-final" inspection. The designer (typically a licensed professional architect or engineer) is usually also incorporated into the contract as the owner's design representative and agent, to verify that completed contract work has complied with the design.

The contractor is bound by the contract to complete a list of contract items, called a punch list, in order to receive final payment from the owner. In the United States construction industry, contract agreements are usually written to allow the owner to withhold (retain) the final payment to the general contractor as " retainage". The list is usually made by the owner, architect or designer, or general contractor while they tour and visually inspect the project. The work may include incomplete or incorrect installations or incidental damage to existing finishes, material, and structures. A punch list is a document prepared during key milestones or near the end of a construction project listing work that does not conform to contract specifications that the general contractor must complete prior to final payment.
