Build-to-Suit Development

A campus designed around your specification — from greenfield site to commissioned halls, engineered for your exact workload.

Your specification, our delivery engine

Build-to-suit is our flagship program: we secure the land, entitle the power, and design and construct the buildings around your technical requirements. You get a campus that fits your roadmap like it was drawn for it — because it was.

From the first test fit to final commissioning, a single Basaltline team owns schedule, budget, and quality. Hyperscale, cloud, and AI providers use the program to enter new markets fast without compromising on design control.

What’s included

Every build-to-suit development engagement covers these six elements — scoped to your capacity and timeline.

  • Site selection & diligence. Market analysis, fiber and power feasibility, wetlands, and permitting risk — packaged into a clear go/no-go.
  • Entitlements & incentives. Rezoning, site plan approval, and negotiated tax and utility incentives handled by our local teams.
  • Custom design & engineering. Basis of design built from your spec: densities, redundancy, cooling topology, and security posture.
  • Construction & commissioning. General contracting, QA/QC, and five-level commissioning through integrated systems testing.
  • Utility & fiber delivery. Substation coordination, diverse fiber entrances, and dark-fiber pathways to major carrier hotels.
  • Operational handover. Documented systems, trained staff options, and warranty management after day one.

How it works

A five-stage path from first conversation to live capacity — with clear gates and open-book reporting throughout.

1. Discover

We map your capacity, power, and timeline targets against our land and power pipeline.

2. Design

Basis of design and test fits converge on a locked scope, budget, and schedule.

3. Entitle

Permits, incentives, and utility agreements are secured in parallel with design.

4. Build

Construction with open-book reporting, owner-side QA, and milestone walkthroughs.

5. Commission

Five-level commissioning and a clean, documented handover to operations.

Common questions

Full control. Your basis of design governs densities, redundancy, cooling, and security — we engineer and deliver to it, with every deviation brought to you for approval.

That is the core of the program. We start from substations with headroom, fund extensions where needed, and pair grid power with on-site generation strategies.

You choose: self-operate with our documentation and training, or retain Basaltline for ongoing operations, remote hands, and maintenance.
