A colocation data center houses IT equipment for several customers in one facility. The operator supplies power, cooling, connectivity, security, and support space. Each tenant receives infrastructure based on its agreement and the facility design.
Each tenant power path must fit within a common system without obscuring ownership, metering, redundancy, access, or future capacity. Colocation data center BIM records those relationships.
Shared Equipment and Tenant Equipment Are Not the Same
Utility services, generators, switchgear, central UPS equipment, cooling, and main pathways may serve several tenants. Downstream panels, rack power, branch routes, and meters may belong to one tenant. The arrangement varies by facility.
Equipment IDs, system names, parameters, and work packages can mark common assets and tenant fit-out work. Data center BIM services can then coordinate shared infrastructure without losing individual scope boundaries.
Shared vs Tenant-Specific Colocation Infrastructure
Infrastructure | Typical arrangement | BIM coordination focus |
Main switchgear | Often shared | Access, capacity information, and feeder exits |
UPS system | Depends on the power architecture | Distribution paths and redundancy |
Main pathways | Often shared | Route allocation and available space |
Tenant distribution | Tenant-specific | Equipment, feeders, and tenant boundaries |
Metering | Shared or tenant-specific arrangement | Location, connections, and identification |
Rack power | Tenant-specific | Final distribution and equipment coordination |
Colocation Data Center Power Allocation Starts Upstream
Tenant power allocation is an engineering and commercial decision based on factors such as contracted capacity, planned load, redundancy, cooling, and later growth. BIM does not perform that study.
Once the allocation is set, electrical BIM services can model the associated switchgear sections, UPS output, PDUs or RPPs, busway, panels, feeders, and rack connections.
A feeder may have adequate capacity but no workable path. Coordinated electrical feeder routing covers entrances, risers, congestion, supports, bends, pulling access, and terminations.
Redundant feeds need separate review. The Uptime Institute Tier Classification System describes topology objectives through capacity components and distribution paths. The word “colocation” alone does not establish the required arrangement.
Metering Has a Physical Side and a Business Side
Tenant metering may include meters, metering panels, current transformers, communication devices, and data connections. Each item needs a location, ID, access, and a clear relationship to the measured load.
The model can show these connections and expose a blocked enclosure or missing communication conduit.
Billing remains outside BIM unless a separate business system is connected for a defined purpose. BIM records the metering equipment; it does not calculate invoices.
Separation Depends on the Facility Design
There is no single separation rule for every facility. Boundaries may come from the electrical architecture, owner standards, security, maintenance procedures, tenant agreements, codes, or reliability strategy.
Tenants may share upstream UPS equipment but use separate downstream panels. Another facility may provide distinct distribution paths. Tenant feed arrangements can also differ within one building.
BIM coordination services can distinguish tenant feeders, trays, busway, rooms, access zones, and shared areas. Names should agree across models, drawings, schedules, and commissioning records.
The team should also check whether maintenance on one tenant’s equipment would obstruct another tenant or require entry into restricted space.
Adding a Tenant to an Operating Hall Changes the Existing Plan
Consider a live facility adding a tenant. The fit-out needs more capacity, redundant feeds, meters, cable tray modeling pathways, and distribution equipment while existing tenants remain active.
The BIM team reviews current site information, spare electrical room modeling positions, feeder exits, overhead space, tray routes, access areas, and MEP systems.
The first route clears electrical equipment but crosses chilled-water pipe and uses space reserved for another tenant. The team changes its elevation and checks it against structure, fire protection, and cooling through MEP BIM services.
Meters are placed where staff can reach them without entering the tenant cage. Both feeds are traced from their sources and checked again before drawings are issued.
The fit-out is treated as a change to an operating facility, not an isolated tenant model.
The Model Must Stay Useful After the Fit-Out
Approved changes should return to the model so equipment tags, panel names, feeder identities, meter references, and tenant assignments agree with the construction documents. This record can support maintenance, later expansion, and data center commissioning when included in scope.
Colocation Data Center BIM Keeps Tenant Systems Traceable
A colocation data center combines shared infrastructure with tenant power, metering, equipment, and pathways. The design team sets capacity, redundancy, and separation. BIM records the resulting arrangement.
Contractors and operators can follow a tenant path through shared space and see what an expansion will affect before work begins.
Frequently Asked Questions
-
What Is a Colocation Data Center?
It houses equipment for multiple customers and supplies shared services such as power, cooling, connectivity, and security.
-
How Is Power Allocated Between Tenants?
Allocation follows the design, capacity, tenant agreement, planned load, and redundancy requirements. BIM records the equipment and routes.
-
How Is Electricity Metered?
Meters are placed at selected distribution points. Their arrangement depends on the facility design and operating requirements.
-
How Does BIM Support Colocation Design?
BIM coordinates equipment, feeders, meters, access, MEP systems, and expansion space.
-
How Are Tenant Electrical Systems Separated?
Separation may involve dedicated equipment, feeders, pathways, identification, access controls, or physical space. It varies by project.
