Medium-voltage switchgear, transformer and cable trays in an electrical plant room

Stage 1 of 14 / Introduction

Write the project brief and design basis

Fix the workload type, capacity target, availability objective, site conditions, utility status, water status and cost boundary before a single number is computed.

Development preview. The calculations on this journey run on existing EngiMetric engines, but the journey text and scope have not completed independent engineering review. The route is excluded from search while it remains a preview.
Professional review required.Engines and workbench are implemented and tested. Defaults, sources and engineering assumptions still require independent review before publication or use on a real project. Current verification state: Needs engineering review.

After this stage you can

Learning objectives
  • State the project type, IT target, rack target, availability objective and operational date.
  • Separate owner requirements, design assumptions and unresolved site information.
  • Explain why grid status and water availability belong in the design basis rather than in a later procurement note.

The engineering

A data-center study fails quietly when the brief mixes owner wishes with verified facts. The project type changes the rack density and load shape. The availability objective changes the topology and cost. Utility capacity, water availability and climate are site facts that must be evidenced, not assumed because a template says so.

This stage separates four kinds of information. Owner requirements are targets such as IT capacity and availability. Assumptions are planning values such as design ambient temperature. Missing information is recorded explicitly, including utility approval and water permits. Verified data is rare in a first-pass study, and the report never labels an assumption as verified.

The default project is a 4 MW mixed AI/HPC campus in a hot coastal climate. It is a teaching case. Every climate, grid, water and cost value must be replaced before a real decision.

Stage assumptions, limits and sources

Provenance

Assumptions

  • The learner owns the project target and the site status labels.
  • Climate values are design assumptions until replaced by a design weather dataset.
  • Grid capacity is a stated figure, not an approved interconnection.

Constraints

  • The workbench is a screening model, not a bankable design or an investment case.
  • One saved state feeds every stage and the exported report.

Limitations

  • No utility study, title search, geotechnical investigation or permit review.
  • No measured climate, water or grid data is bundled with the journey.

Review status

  • Needs engineering review
  • Professional review is required before publication or use as a design basis.
