Final answer:
A turnkey contract would be the better option for installing a naturalistic outdoor pool in your backyard. A cost-plus contract may not be suitable due to uncertain or changing requirements.
Step-by-step explanation:
If you are looking to install a naturalistic outdoor pool in your backyard, a turnkey contract would be the better option. In a turnkey contract, the contractor takes care of everything from design and construction to installation and final completion. This means that you would have a hassle-free experience and the pool would be ready to use as soon as it is completed.
On the other hand, a cost-plus contract may not be suitable for this project. In a cost-plus contract, the contractor is reimbursed for the actual cost of the project plus a fee or percentage markup. This type of contract is more commonly used for projects with uncertain or changing requirements, where the total cost is difficult to determine upfront.
Potential weaknesses of a turnkey contract include limited customization options and potentially higher overall costs. The contractor may have a defined set of designs and features to choose from, which may not suit your specific preferences.
Additionally, since the contractor takes care of all aspects of the project, they may charge a premium for their services. Potential weaknesses of a cost-plus contract include the possibility of cost overruns, as the total cost is not fixed, and potential disputes over the contractor's fee or markup.
