This post takes a look at the enforceability of contract provisions providing for liquidated delay damages after substantial completion. Typically, the assessment of liquidated delay damages ends at substantial completion of a project. However, various standard form contracts, including some of the ConsensusDocs and EJCDC contracts, contain elections allowing for the parties to agree on the use of liquidated damages for failing to achieve substantial completion, final completion, or project milestones. The standard language in the AIA A201 leaves it up to the parties to define the circumstances under which liquidated damages will be awarded.

Courts are split on the enforceability of provisions that seek to assess liquidated damages beyond substantial completions. Courts in some jurisdictions will not impose liquidated damages after the date of substantial completion on the ground that liquidated damages would otherwise become a penalty if assessed after the owner has put the project to its intended use. Perini Corp. v. Greate Bay Hotel & Casino, Inc., 129 N.J. 479, 610 A.2d 364 (1992). When the terms are clear, other jurisdictions will enforce contract terms providing for liquidated damages until final completion, even if the owner has taken beneficial use of the facility. Carrothers Const. Co. v. City of S. Hutchinson, 288 Kan. 743, 207 P.3d 231 (2009).
