Advantages of a Cost + Fee Approach for Construction Projects
When it comes to structuring your construction contract, the delivery method can significantly impact your budget, timeline, and overall risk. One increasingly popular option is the Cost + Fee model—also known as Cost-Plus.
Unlike lump-sum or fixed-price contracts, where the contractor provides a set price upfront, a Cost + Fee approach offers more transparency and flexibility. Here’s why it might be the right choice for your next project.
What Is a Cost + Fee Contract?
In a Cost + Fee arrangement, the owner agrees to pay:
- The actual costs of construction (materials, labor, equipment, subcontractors, etc.)
- Plus a set fee to the contractor, typically a fixed amount or a percentage of those costs.
Sometimes, a Guaranteed Maximum Price (GMP) is added to cap the total spend—but even without it, this model offers several key advantages.
1. Full Cost Transparency
With Cost + Fee, you see exactly where every dollar is going. Contractors are required to submit detailed invoices and backup documentation for all project costs, from subcontractor bills to material receipts.
Why it matters: Owners can better understand the true cost of the work, making it easier to spot trends, identify savings, and ensure money is being spent wisely.
2. Greater Flexibility During Design Changes
Changes happen—whether due to unforeseen site conditions, owner preferences, or design evolution. Under a fixed-price contract, every change can trigger costly change orders.
Why it matters: A Cost + Fee model makes it easier to adapt mid-project without heavy markup or delays. It encourages collaboration instead of friction when scope adjustments are needed.
3. Faster Project Start
Because the contractor doesn’t need to lock in a guaranteed price upfront, construction can often begin before every detail is finalized. This is especially helpful for fast-track projects or those with tight timelines.
Why it matters: Early mobilization means you can hit the ground running—saving precious time during the pre-construction phase.
4. Aligned Interests Between Owner and Contractor
In a lump-sum model, contractors often try to underbid to win the job, then recoup profit through change orders. But in a Cost + Fee setup, the contractor is paid for actual costs plus a fixed fee—so there’s less incentive to cut corners or inflate numbers.
Why it matters: This model fosters a more transparent, collaborative relationship, where everyone is working toward the same goal: a successful, cost-effective project.
5. Opportunity for Shared Savings
Some Cost + Fee contracts include incentive structures that reward contractors for finishing under budget. This keeps teams motivated and gives owners a share of the upside when costs come in lower than expected.
Why it matters: It’s a win-win: you control costs and maintain quality, while the contractor stays invested in the project’s financial success.
Is It Right for Your Project?
The Cost + Fee model is ideal for owners who:
- Want transparency and flexibility
- Are comfortable with open-book accounting
- Have a strong Owner’s Representative or project manager to oversee costs
It may not be the best fit for small, highly defined projects where price certainty is the top priority. But for complex builds or fast-moving projects, it can offer the control and agility you need.
