Data center site offices in Iowa: The Grid, nationwide.

Iowa has 15 data centers under construction and 38 announced as of March 2026, with 58 operating, one of the oldest hyperscale footprints in the country, concentrated at Altoona east of Des Moines, Council Bluffs across the river from Omaha, West Des Moines and Waukee, and Cedar Rapids, according to Aterio.

Iowa is where the hyperscalers went first when they left the coasts: Google to Council Bluffs in 2007, Microsoft to West Des Moines in 2008, Meta to Altoona in 2013, on cheap wind-heavy power, cold air, flat land and a state that wrote the incentives early. The campuses are in their fifth and sixth phases now, and the crews that build them work through winters that reach 20 below on ground that freezes 42 inches down. The office has to be built for that, and this page starts there.

Where are data centers being built in Iowa right now?

Altoona and eastern Polk County. Meta's Altoona campus, east of Des Moines on Interstate 80, has been in construction since 2013 and is one of the largest hyperscale campuses in the country by building count, with phases still going up on the east side.

Council Bluffs and Pottawattamie County. Google's Council Bluffs campus, its first outside the coasts, has grown through a multi-billion-dollar investment and keeps adding buildings on the Missouri River flats across from Omaha, on Interstates 29 and 80.

West Des Moines, Waukee and Dallas County. Microsoft's campuses in West Des Moines are the state's most active construction program, with multiple sites in phase; Apple's announced Waukee campus sits next door in Dallas County.

Cedar Rapids and Linn County. Google's Cedar Rapids campus, announced in 2024, is the eastern Iowa anchor, on Interstate 380 with Alliant's power.

Ames, Story County and the rest. Colocation and enterprise builds follow the hyperscalers along Interstate 35, and campus-scale parcels near Ames and along Interstate 80 are in permitting.

Iowa attracts the work with MidAmerican Energy's wind-heavy grid and some of the lowest industrial rates in the country, a data center sales-and-use tax exemption on qualifying equipment and electricity that the legislature has extended, cold air that cuts cooling cost, and a construction workforce that has built these campuses for eighteen years. Phases and names change quarterly; JOLT checks each project against a county filing or local reporting at every refresh of this page.

Which hyperscalers, developers and general contractors are active in Iowa?

Meta, Google, Microsoft and Apple at campus scale; the colocation operators and developers following them along Interstates 35 and 80.

The general contractors with data center groups working in Iowa include Mortenson, which has built Iowa hyperscale campuses for a decade; Turner; Holder; JE Dunn; Ryan Companies; Kiewit, headquartered across the river in Omaha; and the Des Moines builders that grew up on the campuses, Weitz and Neumann Brothers. Iowa timelines run 14 to 20 months from permit to energized, among the fastest in the country, and the electrical contractor mobilizes its own office on a generator in a January that reaches 20 below.

What does an Iowa data center site office need?

Cold, wind, frost and snow, in that order.

Cold. Des Moines averages lows near 15 degrees in January and sees minus 20 in a bad year; Council Bluffs and Cedar Rapids the same, with wind. A site office that runs on a rooftop package unit or a resistance heater is the office where the crew leaves the heater on and the door open. The Grid carries two 12,000 BTU cold-climate mini-split heat pumps rated to heat at -13 F, behind R-19 closed-cell foam walls and an R-30 roof.

Wind. The Iowa prairie is windy, and tornado season runs April through June. Every Grid receives four-point anchoring; the owner's engineer and the authority having jurisdiction set any project-specific criteria.

Frost. Iowa frost depths run 36 to 48 inches. The Grid is leveled on cribbing at its four corner castings, so the compacted bearing surface must drain away from the doors.

Snow. Thirty-five inches a year, drifting on the prairie. Keep plowed snow away from the office and its two steel personnel doors.

Iowa crews can coordinate the bearing surface, electrical service and truck access with the site-requirements checklist.

How does The Grid get to an Iowa site?

As a legal-width flatbed load, an Iowa-bound Grid needs no oversize permit, pilot car or route survey.

Iowa DC Deploy covers freight, tilt-bed placement or crane set, cribbing and leveling, four-point anchoring, an electrical rough-in walkthrough with the site electrician and pickup at term end; the nationwide delivery page explains the package.

What does a Grid cost on an Iowa data center site?

Iowa projects can review the two Grid builds, deposit, terms and available upgrades on data-center pricing. DC Deploy is quoted per campus.

Iowa sales tax is added where it applies; the state's data center exemption covers the owner's equipment, not a rental office. DC Deploy is quoted for the specific campus.

What is the power picture in Iowa and when does temp power land?

MidAmerican Energy, the Berkshire Hathaway utility, serves Des Moines, Altoona, West Des Moines, Waukee and Council Bluffs, on a grid that is among the most wind-heavy in the country and carries some of the lowest industrial rates. Alliant Energy serves Cedar Rapids. Both carry large-load pipelines measured in hundreds of megawatts and have interconnection programs that commit capacity against long-term contracts. Iowa's power is the reason the hyperscalers came in 2007, and it is still the reason they stay.

For a site office, the utility's timeline matters on the day the office lands. On an established campus at Altoona, Council Bluffs or West Des Moines, temporary construction service is usually live at the gate before the next phase's office arrives. On a greenfield in Dallas or Story County, or at a new Cedar Rapids site, the GC's temporary service can trail the first mobilization by two to six weeks, in winter. Grid Command's 50 A generator inlet with a mechanical interlock lets a generator power the office until the electrician gets a 60 A circuit to the pad; the site electrician sizes the generator and confirms the load plan. JOLT's 25 kW standby generator is $1,850/mo plus fuel.

Do you need a permit for a temporary site office in Iowa?

In Polk, Dallas, Pottawattamie and Linn counties, a temporary construction office is an accessory to the project's building permit and is shown on the site logistics plan with an anchoring detail on file. The cities of Altoona, West Des Moines, Waukee, Council Bluffs and Cedar Rapids follow the same practice, and some fold it into a temporary-use permit with a fee. The Iowa State Building Code applies where a jurisdiction has not adopted its own.

Ask the authority having jurisdiction on the building permit which local requirement applies. Give the data center specialist the county's or GC's anchoring and insurance requests before the delivery window.

How long is an Iowa site office term?

Short and repeated. An Iowa building runs 14 to 20 months from permit to energized, so a single-building placement is a 12-to-18-month term, and JOLT's 12-month minimum with month-to-month after it fits without a renewal. The Altoona, Council Bluffs and West Des Moines campuses have been in phase for a decade and more, and on those the office moves every 12 to 15 months as a building turns over: one or two $1,250 relocations, not a new mobilization.

For a GC or an electrical contractor carrying an office through several Iowa phases, compare rental with the purchase and 36-month lease-to-own rows on the Grid buy page.

How do multi-building Iowa campuses use a Grid Campus?

An Altoona campus in its sixth phase is built one or two buildings at a time, and the GC's project office, the owner's rep, the electrical and mechanical contractors and the security office all move as buildings turn over. The Grid Campus combines 2 to 12 Grids in a row or stacked two-high, with a Stack Kit's stair tower, landing and guardrail for each stacked pair at $395/mo plus $1,500 setup. One order of at least 6 Commands receives a 5 percent rent credit monthly for its first 12 months.

Which Iowa counties and metros does JOLT serve?

All of them. The counties carrying data center construction today: Polk, which is Des Moines and Altoona; Dallas, which is West Des Moines and Waukee; Pottawattamie, which is Council Bluffs; Linn, which is Cedar Rapids; and Story, which is Ames. Other Iowa counties can be quoted too; DC Deploy is quoted per campus in one business day with an on-site window of 6–8 weeks.

Identify the Iowa utility boundary before choosing office power

Do not let the permanent campus power plan stand in for a temporary-office connection plan. Start with the exact parcel and confirm the serving utility, account path and customer-side electrical contractor for the selected office location.

The Iowa Utilities Commission electric overview explains its regulation and coordination role for electric utilities in the state. Use its utility information to verify territory rather than assuming the same provider serves every project along an interstate corridor.

Give the electrical lead a marked plan with the intended Grid position. Ask whether the customer-supplied shore circuit will be ready there when the office arrives. A general statement about campus capacity does not answer that placement question.

If temporary service will trail mobilization, decide whether Command's generator interface belongs in the office scope. The site electrician should confirm source compatibility, owner-added loads and the connection plan. Procurement can then choose the available generator add-on or arrange a compatible source through the project.

Create a separate handoff for shore power. The electrician verifies the temporary service and controls the connection through the provided inlet. The superintendent records that milestone without tying it to permanent building energization.

Match the permit question to the city or county

The authority on the building permit should classify the temporary office before delivery. Verify whether the parcel falls within a city's review boundary or begins with the county rather than routing it from the mailing address.

For an eastern Iowa project, the Cedar Rapids Building Services page is the city's entry point for building review. Ask whether the proposed construction office needs its own application, belongs on the main site plan or requires another approval.

Provide a short equipment description with the Grid dimensions and intended office use. Mark the proposed location, both doors, the access path, bearing area and customer-supplied utility route on the logistics drawing.

Ask the reviewer what anchoring information is required for that parcel. DC Deploy includes four-point anchoring, but the authority and project set site-specific criteria. Send any requested criterion before the delivery window.

Accessibility should be an explicit question, not an assumption. The reviewer and project determine whether the users and route require the ADA ramp option or other site work. Record the answer with the approved office location.

If the office may move to a later phase, ask whether the new position needs another review. Keep the permit reference and authority contact with the relocation plan instead of assuming an approval follows the unit.

Turn Iowa weather alerts into site-office actions

Use the forecast office that covers the project. Consult the National Weather Service Des Moines office and the National Weather Service Quad Cities office when selecting the applicable local forecast and alerts.

Before placement, compare the forecast with the bearing surface, site access and planned delivery method. Wet or frozen ground is a logistics condition for the project team to assess, not a reason to infer performance from a statewide rule.

Assign winter housekeeping around both personnel doors, exterior electrical equipment and HVAC equipment. Keep plowed material away from access paths. Reinspect the bearing area after freeze-thaw changes or drainage problems.

For severe-weather days, connect the office plan to the project's emergency program. A Grid is a site office, not a designated storm shelter. The superintendent should tell occupants where to go and how an alert will be communicated.

Compare Iowa quotes on the same scope

Separate recurring rent from one-time mobilization work. Confirm whether freight, placement, leveling, anchoring, the electrician walkthrough and pickup appear in the offer. DC Deploy includes those items, so a freight-only proposal is not equivalent.

Compare the interior as working space, not merely square footage. Record workstation count, meeting surface, chairs, network equipment and display needs. Note which furniture arrives with the office and which items the project must procure.

For Command, list security and connectivity boundaries. The camera system and Starlink package are included. Badge readers, credentials, owner fiber, utility service and project permits remain customer or vendor decisions.

Tie each optional item to an Iowa project condition. The generator decision follows the electrical plan. The ADA ramp follows the access review. A relocation line follows the phase plan, not a guess about how often a building will turn over.

How do I reserve a Grid for an Iowa project?

Select Core or Command, then provide the Iowa ZIP, unit count, target date and job details using the data-center reservation path. Your confirmation states the delivery window, and a written cancellation more than 14 days before that window opens costs nothing.

How many data centers are under construction in Iowa?

Aterio's March 2026 count records 15 under construction, 38 announced and 58 operating, one of the country's oldest hyperscale footprints.

Does JOLT deliver site offices anywhere in Iowa?

Yes. Iowa's per-campus DC Deploy quote includes freight, tilt-bed placement or crane set, cribbing and leveling, four-point anchoring, the electrical rough-in walkthrough and end-of-term pickup.

How long does delivery to Iowa take?

Allow an on-site window of 6–8 weeks for Iowa.

What does a Grid cost in Iowa?

Iowa rents are $1,950/mo for Core and $2,750/mo for Command, with a 12-month minimum. DC Deploy is quoted per campus in one business day.

Is The Grid built for an Iowa winter?

Yes. Two cold-climate heat pumps rated to heat at -13 F sit behind R-19 closed-cell foam walls and an R-30 roof. The project supplies a level, draining bearing surface and follows its local anchoring requirements.

Who is the utility and how does that affect the office?

MidAmerican Energy serves Des Moines, Altoona, West Des Moines and Council Bluffs; Alliant serves Cedar Rapids. Temp power on an established campus is usually live before the office lands; on a greenfield it can trail mobilization by 2–6 weeks, in winter, which Command's generator inlet covers.

Where are the Altoona and Council Bluffs campuses and can JOLT deliver there?

Meta's campus is at Altoona, east of Des Moines on I-80; Google's is at Council Bluffs on the Missouri River flats across from Omaha. DC Deploy serves both under the same lower-48 package.

How does the Grid hold heat at 20 below on the Iowa prairie?

The Grid has two 12,000 BTU cold-climate heat pumps rated to heat at -13 F, R-19 closed-cell foam walls and an R-30 roof. The site electrician sizes any generator and confirms the load plan.
