The battery rooms only have to carry the load until the generators start. Somebody wires every one.
Surveyors, dirt crews, laborers, concrete crews, ironworkers and roofers build the shell. Riggers set the big gear. Sheet metal workers put in the air handlers, and sprinkler fitters pipe the data hall. Pipefitters set the chillers, and run the chilled water loop that cools the servers. Electricians wire the switchgear, the UPS, and those battery rooms. Fuel crews put in the diesel tanks for the generators. Generator techs then start up the generators, and test them. Low-voltage crews pull the fiber, and the radio cable so firefighters can talk inside. Then insulators, painters and controls techs finish it.
Every one of them has a rulebook. Code Buddy shows what may apply, with the source.

The crew it takes:
Site: surveyors, dirt crews (the big pads), underground electrical duct bank crews, paving and fence crews, laborers
Structure: concrete crews (the slab, tilt-up or precast walls, generator pads), precast erectors, ironworkers (steel, the roof, equipment platforms), roofers, wall panel crews
Systems: electricians (medium-voltage gear, transformers, switchgear, UPS, battery rooms, busway to the racks, generator paralleling, grounding, lighting, fire alarm), pipefitters (chillers, the chilled water loop, cooling to the racks), sheet metal (air handlers, hot-aisle containment), sprinkler fitters (pre-action in the data halls), low-voltage and fiber crews (structured cabling, the fiber backbone, security, the emergency radio), commissioning agents (Level 1 to 5), fire alarm techs
Finishes: insulators (the chilled water), painters, controls and BMS techs
Specialty: linemen (the substation and medium-voltage feeds), crane operators, riggers (generators, transformers, chillers), generator techs, fuel crews, clean-agent fire suppression techs, security and access control crews
