At a Glance

A technology company expanding its GPU test capacity needed permit-ready drawings fast, with confidence that existing mechanical infrastructure could absorb the new electrical load. Pragmatic PE coordinated electrical distribution design and mechanical capacity verification to close that gap before construction began.

Project Description

Lead

A technology company in Santa Clara needed to add GPU test benches to an existing lab space, with permit drawings required before any work could proceed. Pragmatic PE provided electrical engineering and mechanical consulting to ensure the new bench infrastructure was fully coordinated with both the client's operational preferences and the existing building systems. Early verification of cooling capacity and distribution alignment avoided a common retrofit risk: discovering infrastructure gaps only after permit submittal.

Scope of Work

Pragmatic PE delivered coordinated electrical and mechanical scope across the full bench installation.

Electrical Engineering

•   Visited an active comparable installation with the client to verify bench layout and distribution approach before design began

•   Coordinated with client-preferred vendors to select retrofit breakers and new distribution equipment matched to bench load requirements

•   Developed electrical layout providing bench-level distribution and receptacle coverage for all GPU loads

Power Distribution Analysis

•   Performed voltage drop analysis for all new distribution equipment and branch circuits

•   Used SKM fault current analysis to establish short circuit current ratings for new panelboards

Mechanical Consulting

•   Reviewed existing mechanical equipment to confirm cooling capacity against new GPU heat loads

•   Calculated projected loads and verified existing infrastructure could support the added benches without modification

Challenges and Solutions

Constraint: New electrical distribution needed to integrate with an existing system not originally designed for high-density GPU loads.

Response: Retrofit breaker selection was coordinated directly with the client and their vendors to ensure compatibility with existing gear without requiring a full panel replacement.

Constraint: Cooling adequacy for the new benches needed to be confirmed before permit submittal to avoid mid-construction surprises.

Response: Mechanical load calculations were completed early in the process, confirming the existing system had sufficient capacity and eliminating the need for mechanical upgrades.

Constraint: The client had specific preferences for bench configuration informed by an existing comparable installation.

Response: Pragmatic PE conducted a site visit to the reference installation with the client, aligning the design to the client's known outcome before drawings were produced.

Results and Impact

•   Permit drawings delivered with full code compliance and no infrastructure gaps flagged at review

•   Retrofit breaker approach preserved the existing distribution system, avoiding a more disruptive panel replacement

•   Early cooling verification eliminated mechanical upgrade risk from the project scope

•   Active vendor and client coordination produced a buildable design matched to the client's operational preferences
