What is the best contract type used by the owner in construction?

The lump sum contract is the best contract type for owners in construction projects primarily due to its simplicity and clarity. In a lump sum contract, the contractor agrees to complete the project for a fixed total price, which allows the owner to have certainty regarding the total expense of the project upfront. This type of contract mitigates the risk of unexpected costs, providing a clear budget for the owner to rely on.

Additionally, by committing to a lump sum, incentives are created for the contractor to complete the project efficiently and on time because any cost overruns would be absorbed by them rather than the owner. This can lead to better project management and adherence to the schedule, as the contractor has a vested interest in controlling expenses.

Lump sum contracts are particularly beneficial in scenarios where the scope of work is well defined, as they eliminate ambiguity and allow for more straightforward project accounting. This allows the owner to focus more on the completion and quality of the project rather than managing fluctuations in cost.

In contrast, other contract types like cost plus can lead to variable costs and potential for budget overruns, time and materials contracts can become unpredictable with escalating expenses, and unit pricing contracts may not provide the same level of overall cost certainty for the owner.
