Our fees are structured to be proportionate to the value and risk of each project stage. In nearly every case, our involvement saves more than it costs — through better bids, avoided change orders, and problems caught early.

All Engagements Begin with a Free Consultation

We start with a no-cost conversation to understand your project, discuss the right engagement model, and ensure JL Magnus is the right fit before any commitment is made.

Engagements Can Be Combined

Many clients begin with a Feasibility Review or Preconstruction Support, then transition into an Owner's Rep engagement as the project progresses. Services build on each other.

Our Fees Are Typically Recovered

Through tighter bid evaluation, change order management, and risk avoidance, our involvement routinely returns more than the cost of our engagement. We track this for every client.

Scope Is Always Custom

Ranges reflect typical project sizes. Larger or more complex projects may fall above these ranges. All engagements are scoped specifically to your project after our initial conversation.
