Are you a contractor who needs HVAC shop drawings? If so, I can help you. Since 2007 I’ve been creating ductwork and piping shop drawings.
I’m based in NYC, but I take on projects from across the U.S.
My HVAC Shop Drawing Services
My name is Brian M. Curran. I draft ducting and piping shop drawings for HVAC contractors.
Every week I’m completing shop drawings for new projects. I’ve included a few examples of my work you can look through.
Ducting Shop Drawing Sample #1
Below are the mechanical shop drawings I created for the 4th, 9th, and 10th floors of 363 Lafayette Street in New York City. I produced these drawings in 2018, while the building was under construction. The photo above shows the ductwork on one of the building’s floors. And the photo below is of the whole building.
The building was new construction. Its owner and developer was CBSK Ironstate, and it was designed by Morris Adjmi Architects. It was a 10-story, 43,000-square-foot building with brick and terra cotta, angled floors, and a unique wedge-shaped site, as can be seen in my drawings below.
The building had a modern industrial design, so much of the ductwork was exposed architectural duct. Some sections had a flat galvanized finish, while others had a polished finish.
For my scope of work, I only had to draw the distribution duct coming off the AC units. Everything else was already completed on the base job.
On ducting shops, the maximum duct cut length we usually use is 59 inches. That means the duct is fabricated in 59-inch sections and then joined together. For this job, the contractor said we could use that as a dimension in our shops, but he believed the oval ducting would come in 10-foot (120-inch) sections. There was no insulation on the outside—just a 1-inch inner liner for the first 25 feet of the supply duct. Insulation or liner is usually applied to the full length of the supply duct, but the engineer on this job didn’t want that.
The drawings were created in AutoCAD ®. Click the drawing image to launch the actual shop drawings in PDF format.
Ducting Shop Drawing Sample #2
Here is another sample of my duct shop drawings, completed in 2019. For this project, I created ducting shop drawings for the Friends House Retirement Community and Apartments renovation and addition project, located in Sandy Spring, MD.
My shop drawings documented all the ductwork and HVAC components, including coordination with the existing structure and equipment. The ducts ran through attic spaces and between roof framing, with some sections left exposed in the occupied areas. Supply and return ducts were carefully routed to connect to the rooftop units, with transitions provided to tie into existing ductwork. Kitchen hood and dishwasher hood ducts were coordinated with the food service equipment contractor. Existing exhaust ductwork and electric wall heaters were left in place. Fan coil units were located to fit between existing joists, and cabinet heaters were installed recessed in bulkheads. Duct offsets were included to transition between attic spaces, mechanical rooms, and areas just below ceilings. Pressure sensors were provided for the VAV system following the manufacturer’s recommendations. The plans included references to roof and attic layouts to ensure proper continuation and coordination throughout the project.
