Project Overview

• $910 Million Program Value
• 140 MW Campus Electrical System Capacity
• Liquid Cooled Racks + Hot-Aisle/Cold-Aisle Containment
• 326 Rack Test Positions
• Rack-level manufacturing and assembly space, with burn-in rack test

Project Overview

Summit designed the expansion of an existing manufacturing campus with a second-phase building that combines rack-level manufacturing and assembly with burn-in test under one roof. The building houses a 13-position accelerator test line at 74 kW per rack and a 313-position line at 104 kW per rack, both fed from a chilled-water primary system.

For the high-electrical demand system, Summit coordinated with the local utility to provide multiple medium voltage circuits in a very short timeframe.  A robust loop medium-voltage distribution system provides a high degree of maintainability and reliability.  A bridge-power generation system was sourced by Summit and provided to ensure that utility timelines would not be an obstacle to hitting the end-customer’s demanding timelines for production.  The bridge power system fed the campus-wide medium voltage distribution system designed by Summit.

The expansion carries 140 MVA of utility capacity, with the chilled-water plant and process utilities planned from the outset to carry continued rack-density growth beyond this phase.

Customer identity, site designation and product line are confidential and have been omitted in accordance with the terms of Summit’s engagement.

Complex Design Requirements

• Integration of rack-level manufacturing, assembly and burn-in test within a single expansion building tied into an existing campus’s utility and process infrastructure
• Dual-line liquid-cooling design spanning a 13-position accelerator line at 74 kW/rack and a 313-position production line at 104 kW/rack
• 140 MVA utility and central-plant capacity engineered with built-in headroom for rack-density increases beyond the current program
• Coordination with existing campus utility service and process-utility systems to avoid disruption to adjacent, operating buildings

Summit Delivery — Responsiveness That Drives Customer Success

As an expansion to an active, producing campus, this program required Summit’s team to design and sequence construction without interrupting the customer’s existing operations. Summit’s proactive approach to phasing and its responsiveness to the customer’s evolving product roadmap allowed the expansion to be engineered with room for the density growth the customer was already planning for the next phase.

That forward-looking, dedicated approach — designing not just for today’s rack density but for where the customer is headed — is a hallmark of how Summit’s engineering supports its customers’ long-term success.
