Cost plus contracts must contain specific information about certain pre-negotiated amount (some percentage of the material and labor cost) covering contractor’s overhead and profit. Costs must be detailed and should be classified as direct or indirect costs. There are multiple variations for Cost plus contracts and the most common are:

  • Cost Plus with Guaranteed Maximum Price and Bonus Contract

Time and Material

Time and material contracts are usually preferred if the project scope is not clear, or has not been defined. The owner and the contractor must establish an agreed hourly or daily rate, including additional expenses that could arise in the construction process. The costs must be classified as: direct, indirect, mark-up, and overhead. Sometimes the owner might want to establish a cap or specific project duration to the contractor that must be met, in order to have the owner’s risk minimized.
