What you're actually buying
Delivery date, final cost, and how much of your time it takes. Here's how we protect each one.
01 / Schedule
Every bid includes a resource-loaded schedule with named milestones. Your lender, tenants, and broker work from the same calendar we do.
02 / Cost
Open-book GMP pricing built from real subcontractor bids during preconstruction — so the number you approve is the number you pay.
03 / Control
A single principal-level project executive owns your build from first sketch to certificate of occupancy. No hand-offs, no chasing.
Delivered as GC, CM-at-risk, or design-build — whichever fits your capital stack.
Sound familiar?
Most overruns aren't bad luck — they're decided in preconstruction. We fix them there, before a shovel hits the ground.

Why owners choose Northline
I spent a decade as an owner's rep watching good projects bleed money because the builder bid low and recovered it in change orders. I started Northline to be the contractor I wished I could have hired.
We take on a limited number of projects each year so a principal is on every one. You'll have my cell number — and I'll answer it.

Owner perspective
"Northline's GMP came in higher than one other bid. It was also the only number that didn't move. We opened on the exact date our tenant signed for."

FAQ
We take on a limited number of projects per year so a principal can stay on each one. The application lets us confirm fit before either of us spends time on calls — and means your fit call starts with real answers, not discovery questions.
