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.
