Which of the following is NOT one of the minimum elements of a construction contract?

In a construction contract, minimum elements are essential components that outline the fundamental agreements between the parties involved. These typically include key financial aspects, such as the total amount to be paid to the contractor, specifics about progress payments, and any deposit arrangements.

The "number of workers required" is not a standard requirement outlined in a construction contract. While it may be relevant for planning and labor management, it is not considered a minimum contractual element that defines the agreement between the contractor and the client. Contracts focus more on the total costs, payment schedules, and financial implications rather than the specific workforce numbers, which can often vary throughout the project based on changing needs and conditions.

Thus, the option referencing the number of workers required does not align with the core elements needed for a valid construction contract, making it the correct answer in the context of identifying which one is not a minimum element.
