Now Licensed in Arizona: Expanding PE Coverage for the US Data Center Buildout

Paul Waite, PE, SE is now licensed in Arizona — the fifth state on Palisade Engineering's roster, alongside Nevada, California, Utah, and Iowa. The new Arizona stamp lands alongside our recently-added Iowa license, bringing our coverage map into direct alignment with where the US data center buildout is happening fastest. See the full list of licensed states on our about page.

Why Arizona and Iowa

These two states did not end up on our expansion list by accident. Both are in the top five US markets for new hyperscaler and colocation capacity, and both have generated repeat anchorage and structural work for our team over the last two years — work we were previously handing off to local-of-record engineers in each state.

Phoenix metro (AZ). Greater Phoenix — including Mesa, Chandler, Goodyear, and Queen Creek — is tracking as the fastest-growing US data center market outside Northern Virginia. Meta, Microsoft, Apple, Google, QTS, CyrusOne, and EdgeConneX all have active campuses or announced builds. Arizona's seismic demand is lower than Reno's (typical SDS values in the Phoenix basin run roughly 0.20–0.35g, vs. 1.0–1.2g in Washoe County), but Risk Category IV importance factors still apply and wind loading is a meaningful driver for exterior-mounted equipment and generator enclosures.

Central Iowa. Des Moines and Altoona host Microsoft, Meta, Google, and Apple campuses, with steady expansion across West Des Moines and Grimes. Iowa SDS values sit in the low-seismicity range (roughly 0.10–0.20g depending on site class), but IBC 2024 adoption still requires PE-stamped anchorage for Risk Category IV equipment, and anchor design to ACI 318 Chapter 17 does not care what state the slab sits in.

What This Changes for Clients

For data center installers, mission-critical GCs, and hyperscaler project teams working multi-state rollouts, the practical benefit is that one engineering team can carry an anchorage standard across the whole program. Our ASCE 7-22 Chapter 13 methodology stays identical from Reno to Phoenix to Des Moines; only site-specific USGS seismic parameters change. Deliverables look the same, the anchor schedules are formatted the same way, and the PE stamp is on the same set of drawings your inspector in Storey County saw last month.

That matters because the alternative — handing off to a local-of-record engineer in each jurisdiction — usually means reformatted calc packages, a different anchor catalog, different inspection documentation, and a different project manager to chase. Every handoff is a place where edge-distance assumptions, embedment depths, or ICC-ES evaluation references can drift. Keeping one PE stamp across the program eliminates that class of bug.

For our Arizona and Iowa clients specifically: the pricing structure and turnaround times we publish for data center anchorage (Tier 1 at $850/rack, 48–72 hour turnaround; Tier 2 at $1,500–$2,000/unit; Tier 3 from $25,000) apply to projects in both states. Quotes are fixed-price and typically returned within 24–48 hours of receiving equipment cut sheets.

Our Expansion Policy Going Forward

We add states as our clients expand. That is the whole policy. When a current data center or multi-family client tells us they have a project going to ground in a state we are not yet licensed in, Paul typically pursues a comity PE license there — usually a 4–8 week process through NCEES, depending on the state board's paperwork load. We do not believe in accepting projects in states where we do not hold a stamp and routing them through a relationship local-of-record; the engineering responsibility follows the stamp.

If you are planning a project in a state that is not on our current license list, reach out early. In many cases we can time a new license acquisition to meet your submittal deadline.
