A Perfect Lift After Weeks of Winter Challenges

After weeks of bitter cold and unpredictable Ohio weather, we were finally given the kind of day every field crew hopes for. Sunshine. Temperatures in the upper 40s. For Midwesterners, it felt like false spring had officially arrived.

And it arrived at exactly the right time.

This project had been in motion for weeks. Planning, engineering, coordination, scheduling, rescheduling, and constant communication. The kind of project where every detail matters because once the helicopter is in the air, there is no room for hesitation.

When lift day finally came, the conditions were ideal. But getting there took patience and persistence.


The Road to Lift Day

Winter did not make this easy.

Heavy snow events forced delays and cancellations. Crews worked through extreme cold temperatures to keep the project progressing. Schedules had to shift. Equipment timelines had to be reworked. Coordination calls became even more critical.

There is a lot that goes into a rooftop equipment replacement of this scale. Four existing rooftop units had to be safely decommissioned and removed. Structural reinforcement had to be installed. Gas lines modified. Electrical systems adjusted and labeled. Curb caps fabricated and set. New Cambridge make up air units staged and ready.

Every step had to align perfectly with the lift schedule.

When weather interferes, it tests the strength of planning and communication. It also tests the team’s ability to stay focused on the end goal.


Precision on Lift Morning

Lift day began early.

Our team was onsite at 6:00 AM.
The helicopter ground crew arrived at 6:30 AM.
Sunrise was at 7:34 AM.
The helicopter arrived just after sunrise.

There is something powerful about that moment. The air is still. Everyone knows their role. Weeks of preparation come down to a few critical hours of execution.

Four rooftop units removed.
Four Cambridge make up air units set into place.

The coordination between crews, rigging teams, structural partners, electricians, and safety personnel was seamless. Clear communication carried across the roof and the ground team. Every movement was deliberate.

It could not have gone more smoothly.


The Value of Communication

We partnered with Atomatic Mechanical Services on this project, working closely with Brett Johnson and his team throughout the process.

Brett shared:

“We really appreciate the great communication on this project.”

That feedback reflects what made this lift successful. Projects like this are not won on lift day alone. They are won in the planning meetings, the engineering reviews, the safety walkthroughs, and the daily check ins when conditions are less than ideal.


Why the Win Feels Different

There is something especially rewarding about a day like this after battling winter delays and long hours of coordination.

When you have worked on something for weeks, adjusting details, reviewing drawings, confirming timelines, and preparing for every possible scenario, a successful lift feels bigger than just completing a task.

It feels earned.

The team onsite felt it. The collaboration. The trust. The shared focus. Everyone pulling in the same direction to execute safely and efficiently.

Four outdated rooftop units are gone.
Four new units are in place.
Structural, gas, and electrical systems are upgraded and ready.

But more than that, it was a reminder of what strong teamwork and preparation can accomplish.

False spring may not last long in Ohio. But on this day, it showed up right when we needed it most.

WPAFB Sensors Lab

Wright-Patt Air Force Base sought contractors to renovate and add onto the Sensors Lab. The HVAC portion of the project was over $13 million.

  • MSD served as the Design Assist Contractor in conjunction with Heapy Engineering for this project. In collaborating with General Contractor, Butt Construction, MSD provided Design Assist solutions for the following:
    • A large, anechoic chamber
    • An outdoor range
    • Multiple, Class-100 clean rooms
    • A three-story office building addition with DCID 6-9 requirements on many of the rooms

WPAFB Chilled Water System

The chilled water system at a high-security building on the Air Force Base was undersized and unable to keep up with demand. The facility could not operate without chilled water due to the amount of information servers in the building, and the general nature of the building itself. The entire upgrade project would need to be completed with minimal shut down time at the building. HVAC portion of this project was over $3 million.

  • MSD worked in collaboration with Diaz Construction to complete the system upgrades on time and on budget with minimal shutdowns or disruption to the facility operations.

LJB, Inc.

LJB, Inc. was renovating their Miamisburg, OH office and wanted to incorporate energy-saving upgrades.

  • MSD provided Design Build services in tandem with Greensleeves Energy Solutions, a specialist in geothermal systems.
  • MSD and Greensleeves installed a new geothermal HVAC system with open and closed loops. In addition, MSD design and installed the plumbing portion of the renovation.
