Mission Critical Construction

Mission critical facilities are built for zero-fail moments. Data centers and infrastructure hubs power the systems people rely on every minute of the day, often without realizing it. When everything is working, no one notices. When it’s not, nothing else matters.

A Dedicated Mission Critical Builder

At Clune, Mission Critical construction is a core practice. Our teams specialize in data center construction where uptime, safety, and speed to market are non-negotiable. We bring deep field experience, national reach, and a builder-first mindset to every project.

Built from the Top Down

We approach Mission Critical projects with early MEP coordination, a robust procurement strategy, and constructability planning that starts long before work begins in the field. By identifying risk early and sequencing work intentionally, we help owners protect both schedule and long-term performance.

Speed Without Compromise

Our delivery model supports aggressive go-live timelines through phased turnover, concurrent scheduling, rigorous QA/QC, and commissioning integrated from day one. From greenfield data center campuses to live-site expansions, every project is meticulously planned, tested, and verified.

Proven at Scale

Clune delivers complex Mission Critical projects across the country, partnering with leading data center developers, owners, and operators. The measure of success is simple: facilities that perform on day one and every day after.
