Quick answer

On Wyoming public works, a public entity may retain no more than 5% of the calculated value of completed work, held in an account in the contractor's name assigned to the entity (W.S. 16-6-702(b)). After it certifies substantial completion and publishes notice for two consecutive weeks, it pays the general contractor on the 41st day after the notice first ran, less amounts for incomplete or nonconforming work.

Retainage cap
5%
A public entity may retain no more than 5% of the calculated value of completed work, and the retained payment must be held in an account in the contractor's name that is assigned to the public entity. The article does not apply where federal or other outside funding imposes inconsistent retention or payment requirements (W.S. 16-6-706).
Deadline
41 days
Substantial completion: the public entity issues a certificate of substantial completion, publishes notice weekly for two consecutive weeks and posts it, and payment of retainage falls due on the 41st day after that notice was first published and posted, less amounts withheld for incomplete or nonconforming portions (which are paid at final completion).
What the statute says
In all contracts with a public entity for a public work, the public entity may retain no more than five percent (5%) of the calculated value of any work completed as retainage. The retained payment shall be due and payable as prescribed by W.S. 16-6-116(a). The retained payment shall be held in an account in the name of the contractor which account has been assigned to the public entity.

Who this applies to

The retainage provisions of Title 16, chapter 6 apply only to contracts with a public entity for a public work [1], and that is the only setting this page covers. For a private job, the answer lies in the contract and with a lawyer who has read it.

Within public work, the rule runs between the public entity and the general contractor it pays. It gives way where federal or other outside funding imposes retention or payment requirements that are inconsistent with it (W.S. 16-6-706) [1].

What the rule says

In all contracts with a public entity for a public work, the entity may retain no more than 5% [1] of the calculated value of any work completed. The retained payment is kept in an account in the contractor's name, and that account is assigned to the public entity.

The percentage does not step down on its own, but early release is possible. If the entity finds that satisfactory progress is being made in all phases of the work, it may, on the contractor's written request, authorize payment from the withheld percentage, after deciding that satisfactory and substantial reasons exist and obtaining written approval from any surety.

Normal release follows a published timetable:

  1. The public entity issues a certificate of substantial completion.
  2. Notice is published once a week for two consecutive weeks [1] and posted.
  3. On the 41st day [1] after the notice was first published and posted, the entity pays the general contractor the retained payment together with any other amount due under the contract.
  4. Money for any portion that is incomplete, or not done in accordance with the contract and its documents, can be held back; it is paid at final completion.

How to comply

Two related sections fill in the picture: § 16-6-703 deals with completion of the work by the public entity and how the retained payment is applied, and § 16-6-117 covers claims against the general contractor's surety bond [1]. The statute text and the contract are the final reference for a given project.
