Tight deadlines demand meticulous planning and proactive communication—both of which were essential to the success of our recent HVAC dunnage steel detailing project in New York. With only days to act before a crane pick, our team delivered accurate, approval-ready steel drawings on time—without compromising quality.
The Challenge:
This project involved designing and detailing a rooftop steel dunnage structure for HVAC equipment under significant time constraints. The crane pick date had already been scheduled, meaning we had just three days to:
- Model the structure
- Generate fabrication drawings
- Obtain approval
- Send the steel for galvanizing and delivery
The window was tight, and every hour mattered.
Our Expertise:
To meet the timeline, we prioritized proactive coordination. Right at the start, we raised critical questions regarding steel elevations and the exact HVAC unit footprint. Instead of waiting for formal submittals, we obtained “quick RFI” responses—enabling us to move forward confidently and avoid downstream delays.
We worked closely with the fabricator to align our model with shop preferences, minimizing back-and-forth and allowing steel processing to begin while approvals were still underway.
The Result:
Thanks to clear communication and disciplined detailing, we completed the model and shop drawings on time. The steel was delivered as scheduled, and the crane pick took place without a hitch.
This HVAC dunnage steel detailing project highlights how the right mix of urgency, accuracy, and teamwork can turn tight deadlines into smooth deliveries. Our ability to deliver under pressure reflects our broader commitment to efficient, high-quality structural steel detailing.
