Hyperscale vs. Colocation: Different Builders for Different Needs

Not all data center construction is the same. A hyperscale campus being built for a major cloud provider and a colocation facility designed for multiple tenants share the same fundamental purpose — housing IT infrastructure — but the similarities largely end there. The design philosophy, construction approach, contractor requirements, workforce needs, and cost dynamics differ significantly between these two segments.

Understanding these differences matters whether you are a data center construction company deciding where to focus, a developer selecting a contractor, or a workforce provider like Cortex Construct deploying tradespeople to different types of projects.

Scale and Scope

The most obvious difference is scale.

Hyperscale Facilities

Hyperscale data centers are designed for a single operator — typically a cloud provider (AWS, Microsoft Azure, Google Cloud), a large technology company (Meta, Apple), or an AI company building dedicated training infrastructure.

Key characteristics:

• Building size: 200,000-500,000+ square feet per building
• Power capacity: 50-100+ MW per building, with campus totals reaching 500 MW to 1 GW+
• Campus model: Multiple buildings on a single campus, built in phases over years
• Construction value: $500 million to $5+ billion per campus program

Hyperscale construction is defined by repetition at enormous scale. A campus might consist of 8-12 nearly identical buildings built in a phased sequence, each designed to house standardized compute pods optimized for the operator's specific hardware and workload requirements.

Colocation Facilities

Colocation data centers are designed to house multiple tenants, each renting space, power, and cooling within a shared facility.

Key characteristics:

• Building size: 50,000-200,000 square feet per building (though some modern colos are larger)
• Power capacity: 10-50 MW per building
• Build approach: Often single buildings or smaller multi-building campuses
• Construction value: $50 million to $500 million per project

Colocation data center construction is defined by flexibility. Because the operator does not know exactly who the tenants will be or what their requirements will be at the time of construction, the facility must accommodate a range of power densities, cooling configurations, and security requirements.

Design Philosophy

The design differences between hyperscale and colocation facilities have direct implications for construction.

Hyperscale Design

Hyperscale facilities are purpose-built for a known workload and a single operator. This allows for extensive optimization:

• Standardized pods: Identical server rooms with identical power and cooling configurations
• Custom cooling: Cooling systems designed for specific heat loads, often including liquid cooling for AI workloads
• Simplified redundancy: Operators may accept lower facility-level redundancy (N+1 instead of 2N) because they build redundancy at the software and campus levels
• Streamlined finishes: Minimal architectural finishes — function over form
• Custom power architecture: Power distribution optimized for known rack densities

Colocation Design

Colocation facilities must balance efficiency with flexibility:

• Variable power density: Ability to support tenants ranging from 5 kW to 50+ kW per rack within the same facility
• Modular suites: Individually secured spaces (cages, suites, private data halls) for different tenants
• Higher redundancy: Typically 2N power and N+1 cooling to meet SLA requirements across diverse tenants
• Better finishes: Customer-facing spaces (meet-me rooms, lobbies, NOCs) require commercial-quality finishes
• Flexible infrastructure: Power and cooling systems that can be reconfigured as tenants change

Contractor Selection

The type of contractor best suited for each segment differs based on the construction requirements.

Contractors for Hyperscale

Hyperscale programs favor large general contractors with specific capabilities:

1. Program management capacity: Ability to manage multi-phase, multi-year campus construction programs
2. Workforce scale: Capability to mobilize 2,000-5,000+ workers across overlapping building phases
3. Prefabrication capability: In-house or partnered prefab facilities for producing modular components at scale
4. Bonding capacity: Ability to bond individual phases worth $200-500 million+
5. Repeat execution: Ability to deliver the same design repeatedly with improving efficiency

The hyperscale data center construction segment is dominated by a relatively small number of firms because few contractors can meet all of these requirements simultaneously.

Contractors for Colocation

Colocation construction engages a broader range of contractors:

1. Technical versatility: Ability to build flexible infrastructure that supports varying tenant requirements
2. Speed to market: Colocation operators are intensely focused on time-to-revenue; fast delivery is critical
3. Cost management: Colocation operates on thinner margins than hyperscale, making construction cost control essential
4. Tenant improvement capability: Experience building out individual tenant suites within shell facilities
5. Phased delivery: Ability to deliver some capacity quickly while continuing construction on remaining phases

Colocation projects are accessible to a wider range of contractors, including regional firms and specialist data center builders that may not have the scale for hyperscale programs.

Workforce Requirements

The workforce profiles for hyperscale and colocation construction differ in important ways.

Hyperscale Workforce

Hyperscale projects require enormous labor forces concentrated at a single site:

• Peak headcount: 2,000-3,000+ workers per building during peak construction
• Trade mix: Heavy electrical (30-35% of labor hours) and mechanical (20-25%), with growing pipefitter demand for liquid-cooled facilities
• Duration: Individual buildings typically take 12-18 months; campus programs run for 5-10 years
• Travel workforce: Often 40-60% of workers on a hyperscale project are travel workers brought in from other markets

The scale of hyperscale workforce requirements creates significant logistical challenges. Housing, parking, site access, and worker rotation all require careful planning. A major hyperscale campus can be the single largest employer in a county.

Colocation Workforce

Colocation projects require smaller but often more versatile crews:

• Peak headcount: 200-800 workers during peak construction
• Trade mix: Similar electrical and mechanical proportions, but with more architectural and finish trades
• Duration: Individual buildings typically take 10-14 months
• Local workforce: Higher proportion of local workers due to smaller project size and less market concentration

Colocation projects may also require ongoing construction crews for tenant improvement work — building out individual suites as new tenants sign leases. This creates a more continuous, lower-intensity workforce need compared to the surge-and-release pattern of hyperscale construction.

Cost Comparison

Construction costs differ between the two segments for structural reasons.

Hyperscale Cost Advantages

Hyperscale projects benefit from several cost advantages:

• Standardization: Building the same design repeatedly reduces design costs and improves construction efficiency
• Volume purchasing: Equipment procurement at campus scale commands significant discounts
• Campus infrastructure: Shared site infrastructure (substations, water treatment, roads) is amortized across multiple buildings
• Design optimization: Purpose-built designs can be optimized more aggressively than flexible designs

These advantages typically put hyperscale construction costs in the $7-10 million per MW range, though AI-optimized facilities with liquid cooling push higher.

Colocation Cost Considerations

Colocation construction typically carries higher per-MW costs:

• Flexibility premium: Building flexible infrastructure costs more than optimized, single-purpose infrastructure
• Higher redundancy: 2N power systems and higher-tier cooling add cost
• Finish quality: Customer-facing areas require commercial-grade finishes
• Smaller scale: Less ability to capture volume discounts and campus efficiencies

Colocation construction costs typically range from $10-15 million per MW, depending on market, tier level, and design specifications.

Choosing Your Focus

For construction companies and workforce providers, the choice between hyperscale and colocation work involves trade-offs.

Why Focus on Hyperscale

• Larger individual project values
• Multi-year program relationships with repeat revenue
• Standardized work that improves crew efficiency
• Premium labor rates driven by scale and urgency

Why Focus on Colocation

• More projects and clients to diversify risk
• Accessible to smaller contractors
• Ongoing tenant improvement work creates steady demand
• Less client concentration risk

Many successful construction companies and staffing firms serve both segments, adjusting their approach based on the specific requirements of each project type.

What This Means for Workforce Planning

Whether a project is hyperscale or colocation, workforce availability remains the critical constraint. The differences in scale, timing, and trade mix require different staffing strategies:

• Hyperscale: Requires large-scale mobilization and sustained deployment, heavy reliance on travel workforce, and close coordination between GC and staffing partners
• Colocation: Requires faster ramp-up and ramp-down cycles, more local workforce utilization, and flexibility to support tenant improvement schedules
