Cost Plus Contract in Construction: Understanding the Pros, Cons, and Appropriate Use

A cost plus contract is a popular type of construction contract used in the industry, particularly for projects where the scope or requirements are uncertain or subject to change. In a cost plus contract, the owner agrees to reimburse the contractor for the actual costs incurred during construction, along with an agreed-upon fee or percentage of the costs as compensation. While cost plus contracts offer certain advantages, they also come with their own set of challenges. Understanding the pros, cons, and appropriate use of cost plus contracts is essential for contractors and project stakeholders. In this blog post, we will explore the concept of cost plus contracts in construction and delve into their benefits, drawbacks, and best practices for implementation.

How Cost Plus Contracts Work

In a cost plus contract, the contractor is compensated for the actual costs incurred in carrying out the construction work. These costs typically include:

• Direct Costs: Direct expenses related to labor, materials, and equipment directly used for the project.
• Indirect Costs: Overhead expenses not directly attributed to a specific project but necessary for overall operations (e.g., insurance, administration, and general supervision).
• Agreed Fee: An additional fee or percentage of the total costs, which serves as the contractor's profit and overhead compensation.

The contract may specify a maximum amount for reimbursement, known as the "not-to-exceed" amount, beyond which the contractor cannot claim additional expenses without prior approval from the owner.

Pros of Cost Plus Contracts

Cost plus contracts offer several advantages, making them suitable for certain types of construction projects:

• Flexibility: Cost plus contracts are highly flexible and adaptable to changes in project scope or design, making them ideal for projects with uncertain or evolving requirements.
• Transparent Costing: Owners have clear visibility into project costs, including itemized expenses and fee breakdowns, promoting transparency and accountability.
• Fast Project Initiation: Cost plus contracts allow projects to commence quickly, even without finalizing all design details, which can be advantageous for time-sensitive or urgent projects.
• Collaborative Approach: This contract type fosters collaboration between the owner and the contractor, as both parties share the risk and reward of the project's outcome.
• Incentive for Efficiency: Contractors have an incentive to complete the project efficiently since their profit depends on minimizing costs and avoiding unnecessary expenses.
• Quality Focus: Contractors are motivated to prioritize quality workmanship, as their reputation and future opportunities rely on delivering a satisfactory project.

Cons of Cost Plus Contracts

While cost plus contracts offer advantages, they are not without challenges:

• Budget Uncertainty: Owners may face uncertainty regarding the final project cost, especially if changes are frequent or if the contractor's costs are not adequately controlled.
• Less Cost Control: The owner has limited control over cost management, relying on the contractor's accountability for expenses.
• Potential for Disputes: Disputes can arise over the reasonableness of costs, scope changes, and the appropriate fee percentage, leading to strained relationships between the owner and contractor.
• Contractor's Fee: If the fee percentage is not appropriately structured, it may inadvertently incentivize the contractor to increase costs to earn a higher fee.
• Complex Accounting: Proper record-keeping and accounting are crucial for accurate cost tracking and reimbursement, adding administrative burden and costs.
• Not Suitable for Fixed-Budget Projects: Cost plus contracts are not suitable for projects with fixed budgets, as the final cost may exceed expectations.

Appropriate Use of Cost Plus Contracts

Cost plus contracts are best suited for certain types of construction projects, including:

• Projects with Uncertain Scope: When the project scope is not well-defined or is subject to frequent changes, a cost plus contract provides flexibility for adjustments.
• Time-Sensitive Projects: For urgent projects with tight schedules, cost plus contracts expedite project initiation without prolonged contract negotiations.
• Complex or Unique Projects: Projects with unique technical challenges or specialized requirements may benefit from the collaborative approach of cost plus contracts.
• Projects with Evolving Design: Cost plus contracts accommodate projects with evolving designs or where detailed plans are not fully available at the outset.
• High-Risk Projects: For projects with inherent risks, sharing the risk and reward through a cost plus contract can align interests and promote cooperation.

Best Practices for Cost Plus Contracts

To maximize the benefits of cost plus contracts and mitigate potential drawbacks, the following best practices are recommended:

• Clear Communication: Establish open and transparent communication between the owner and the contractor regarding cost expectations, fee structure, and budget limitations.
• Thorough Documentation: Maintain comprehensive records of all project costs and expenses, including detailed invoices, receipts, and change orders.
• Cost Controls: Implement effective cost controls, regular monitoring, and approval processes to manage expenses within the agreed-upon budget.
• Well-Defined Change Order Process: Establish a clear process for managing changes to the project scope or design, ensuring timely approval and cost adjustments.
• Reasonable Fee Structure: Agree on a fee percentage that incentivizes cost efficiency while still providing a fair profit margin for the contractor.
• Regular Reporting: Provide regular cost reports and project updates to keep the owner informed about project progress and financial status.
• Not-to-Exceed Clause: Consider including a "not-to-exceed" clause in the contract to limit the maximum reimbursement amount without prior approval.

Conclusion

Cost plus contracts offer flexibility and transparency for construction projects with uncertain or evolving scopes. They promote collaboration between the owner and contractor and incentivize efficiency and quality. However, cost plus contracts may not be suitable for all projects, and careful consideration of their pros, cons, and appropriate use is essential. By implementing best practices and effective cost management, stakeholders can make the most of cost plus contracts to deliver successful construction projects that meet budgetary constraints and client expectations.
