What’s Cost Plus Contract?
The client agrees to cover the real project costs in a building cost-plus agreement. These expenses include equipment and labor, plus additional expenses incurred in completing all works. The “plus” part refers to a fixed fee or percentage agreed upon in advance that covers the contractor’s overhead & profit. Typically, these contracts are “open book,” meaning the owner has the right to see actual expenses. In construction, some cost-plus agreements involve a guaranteed maximum price. This type of contract is different from Lump Sum Contract.
Main components of a cost-plus-contract:
The main contractor uses materials, supplies, labor, machinery and professional consultant.
2-Overhead costs/ indirect costs:
All related expenses that are needed to perform the contract; typically a percentage of labor costs and can include office rent, insurance, office supply, communication expenses, mileage, and printing or reproduction of construction drawings
3-Fee or profit:
Typically a fixed percentage (%) based on the cost of labors directly associated with the work
When to Use a Cost-Plus Contract
This type of contracts may be used when the budget is being restricted or when there is a high probability that the actual cost of works might be reduced. A cost-plus contract is preferred when there is not enough data to perform a detailed estimate of the work or when the design is not completed. Governmental agencies prefer these contracts because they can select the contractor based on their qualification instead of the low bidder. Cost-plus is widely used to perform research & development works because the risk can be controlled by the contracting officer.
