The U.S. data center build-out, tracked and sourced.
What we see across the market, how a data center job runs, and why trade change work goes unbilled. Every figure links to a published source.
Record spending, record-low vacancy, and a hard limit on power and people.
Figures as of November 2026.
- U.S. private data center construction reached a record annual rate of about $96.5B in September 2026, up about 90% from a year earlier (preliminary Census data).[1] It first passed $50B in April 2026.[2]
- Amazon, Alphabet, Meta and Microsoft plan roughly $700B to $830B of 2026 capital spending, and each raised or held its outlook.[3,4]
- North American data center vacancy hit a record low of 1.4% in the first half of 2026, with a record amount under construction.[5,6]
- Electricians are the most-cited shortage on data center builds, with pipefitters second; labor shortages are delaying projects.[8,9]
- Build cost is about $11.3M per MW for shell and core (JLL) and $8.9M to $23.3M per MW all-in (Cushman & Wakefield), up about 21% since late 2024.[24,25]
- Published breakdowns put electrical at roughly 40% to 50% of build cost and mechanical at roughly 15% to 20%.[26,27]
- Many 2026 projects are delayed, mostly by power, equipment and approvals; trackers show more delays than outright cancellations, and the "half canceled" claim is disputed.[10,11,12]
- JLL found 57% of data center projects were delayed at least three months in 2025.[16]
Six stages from land to turnover.
Published estimates run from about 18 to 30 months end to end where approvals are quick, to 4 to 7 years where they are not.[17,19,18]
- 01
Site and power
Owner or developer, utility, grid operator
Land, grid capacity, water and cooling decide whether a site works at all; power is often the binding constraint, and some teams turn to on-site generation.[17,20]
- 02
Entitlements and permits
Developer, county and state agencies, residents
Approvals run across federal, state and local agencies; zoning and environmental reviews are common causes of delay.[18,17]
- 03
Design and procurement
Owner, design engineers, general contractor, vendors
Engineering covers power distribution, cooling and redundancy.[17] Long-lead gear such as large transformers has been reported at around 36 months.[7]
- 04
Construction
General contractor, electrical, mechanical and other trades
Site work, utilities and the electrical and mechanical systems.[17] Electricians are the most-cited labor shortage, with pipefitters next.[8] Changes arrive through verbal directives and unacknowledged notices, and owners push acceleration to hit lease milestones.[13]
- 05
Commissioning
Commissioning agent, trades, owner operations
Commissioning runs from factory checks (L1) to integrated systems testing (L5), and guides recommend running it alongside construction rather than at the end.[21,22,17]
- 06
Turnover and operations
Owner operations, facilities contractors
Continuous monitoring, maintenance and compliance after commissioning.[17]
Commissioning levels, L1 to L5.
Each project's specification sets the exact definitions; these are the common meanings.[21,22,23]
- L1Factory and component checksFactory acceptance tests, certifications and documents before equipment ships.
- L2Installation checksCabling, piping, torque, terminations, earthing and labeling against the drawings.
- L3Start-upEach device (UPS, generator, pump, CRAH) energized and checked on its own, with alarms and control points.
- L4Functional performanceWhole systems and control sequences tested in normal and failure modes, such as utility loss to generator to UPS.
- L5Integrated systems testThe full facility tested as one system under simulated failures; may include load banks and heat load.
Why extra work on data center jobs goes unbilled.
What construction claims practitioners report on these projects.
- 01Owner and GC direction given verbally and never turned into a formal change order, plus change notices nobody acknowledges.[13]
- 02Acceleration to hit tenant lease milestones, bringing overtime, extra shifts and compressed commissioning.[13]
- 03Money spent to recover from delays caused by others is usually recoverable only if it was agreed in advance.[14]
- 04Constructive acceleration: owners refuse time extensions, so trades speed up at their own cost.[15]
- 05Scope ambiguity, incomplete design documents and tenant-driven changes produce contested change orders.[13]
- 06Mixed-up job-cost records make recovery harder.[13]
