Get the engineering your project needs
Most firms sell you a stamped set of drawings. We'd rather get the numbers right first.
We provide professional load calculations, detailed plans, and submittals tailored to meet the technical requirements of diverse building projects.
Load calculations
Accurate heat gain and loss calculations sized to your building, not a rule of thumb.
Detailed plans
Complete mechanical plans that your mechanical contractor can actually build from.
Submittals
Equipment submittals prepared to match the specs we wrote, so the review process moves fast.
Three scopes, one standard of accuracy
Pick the deliverable your project needs. Every engagement gets the same technical review before anything leaves our desk.

ASHRAE-based load calcs for a single building system, delivered as a clear summary.

Priority turnaround
Plans that pass review the first time.
JW Designs delivered our load calcs on time, and the plans came back from review with zero comments. That has never happened for us before.
Michael Torres
Project Manager, multi-family developer
The submittal package was complete and code-compliant. We did not have to chase a single revision, which kept our timeline intact.
Dana Whitfield
General Contractor, light commercial
Clear technical work and fast turnaround. The plans matched what the building actually needed, so we had no surprises in the field.
Robert Chen
Principal, commercial architecture firm
We brought JW Designs in late on a commercial build. They got the plans done on schedule and the submittal passed without a single correction.
