A punch list is a document prepared near the end of a construction project listing work not conforming to contract specifications that the contractor must complete prior to final payment. The work may include incomplete or incorrect installations or incidental damage to existing finishes, material, and structures.
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 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. 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.
In most contracts, the General Conditions to the Contract for Construction requires the Contractor, when he believes it to be so, to declare the construction project to have reached "substantial completion" and request a "pre-final" inspection. 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. This snag list, generated by the Contractor is known as the punch list. Upon receipt of the Contractor's list, the Architect then inspects the work to determine if the Work is "substantially complete." Final contractor payment is made when the punch list of items are completed to meet the project design required by the contract, or some other mutually agreed resolution for each item is reached. Examples of punch list items include damaged building components (e.g. repair broken window, replace stained wallboard, repair cracked paving, etc.), or problems with the final installation of building materials or equipment (e.g. reinstall peeling carpet, replace missing roof shingles, fire and pressure test boiler, obtain elevator use permit, activate security system, etc.).
The phrase takes its name, under one hypothesis, from the historical process of punching a hole in the margin of the document, next to one of the items on the list. This indicated that the work was completed for that particular construction task. Two copies of the list were punched at the same time to provide an identical record for the architect and contractor.
Construction punch list software
Starting in 2013 when mobile software became popular on construction sites, many construction teams started using software to manage their punch lists. Today there are a variety of punch list software out there, ranging from simple mobile apps to more comprehensive web and mobile platforms. Many construction teams have found that they are able to deliver better quality construction when they use the construction punch list software. Some examples of construction punch list software are CMiC, Construct App, Bluebeam Revu, Closeout, BIM 360 Field, Procore, Fieldwire, ArchiSnapper, PlanGrid, SKYSITE and Latista.
There are many advantages to deploying punch list software in construction. Punch list software can help in organizing punch list items by using filters such as location (by floor or room number), assignees, task stages, date (by creation or due date), deficiency number, and even by item punch list title. The deployment of punch list software on and off-site can assist in creating a collaborative environment between individuals and groups, by automating manual processes generally associated with the construction industry, and in providing a software platform that is not only easy to use, but user-friendly as well. It is important to note that there are environmental advantages to punch list software because it is a paperless technology that can be shared with other individuals and groups.
