Cost-Plus vs. Fixed Bid: Why Developers Are Switching

If you've ever finished a construction project and wondered where an extra $500K went, you're not alone. The fixed-bid model is designed to hide that answer from you.

The Fixed-Bid Illusion

Here's how it works: A general contractor gives you a number. It feels solid. It feels safe. You sign the contract thinking you know exactly what you're paying.

Then the change orders start.

“We hit rock during excavation.” “The city requires an additional inspection.” “Material prices went up since we bid.” Every one of these is a new invoice. And every one of them was predictable — the GC just didn't include it in the original bid because a lower number wins the contract.

By the time you're done, you've paid 20-30% more than the “fixed” bid. And you still have no idea what the actual costs were versus the contractor's margin.

How Cost-Plus Actually Works

Cost-plus is simple: you pay the actual cost of labor, equipment, and materials — plus a transparent percentage fee for management and oversight.

Every receipt is yours to see. Every invoice is documented. Every dollar is accounted for. There's no incentive for us to inflate costs because our fee is a percentage — if we save you money, we earn your trust and your next project.

The Math That Matters

Fixed Bid: $10M bid + $2.1M in change orders = $12.1M total (you see none of the breakdown)

Cost-Plus: $9.2M actual costs + 12% fee ($1.1M) = $10.3M total (you see every line item)

That's $1.8M saved — and full visibility into where every dollar went.

Why Most GCs Won't Offer This

Because transparency kills their margins. A traditional GC makes money by bidding high and spending low. The gap between what they charge you and what they actually spend is their profit — and they never want you to see that number.

We flip that model. Our profit is a known percentage. Our incentive is to deliver your project efficiently, on time, and at the lowest real cost — because that's how we earn repeat business.

Who This Model Is For

Cost-plus owner's representation works best for developers, investors, and organizations building at scale — subdivisions, commercial projects, data centers, warehouses, retail, and housing developments. If your project is $1M+, this model will save you money and give you control you've never had before.

The Bottom Line

Fixed-bid contracts exist to protect the contractor. Cost-plus exists to protect you. If you're tired of surprises, inflated numbers, and contractors who dodge your questions — let's talk.
