What it means
Where the architect's and engineer's drawings show design intent, shop drawings show the specific details: dimensions, connections, materials and fastening. Typical examples include millwork, metal work, glazing, ductwork and electrical equipment layouts.
They are reviewed before fabrication starts, because once something is built to the wrong detail it is hard and costly to change.
Why it matters
Shop drawings are the last check before money is spent on materials. They help catch conflicts between trades, wrong dimensions and non-compliant products. Skipping or rushing the review is a common source of rework.
For owners, this step is where custom elements, such as feature millwork or specialty ceilings, are confirmed to look as imagined.
How HSM handles it
HSM prepares and checks shop drawings with a coordinated eye. Our carpentry and millwork team produces its own details, and our mechanical and electrical teams lay out ducts, pipes and equipment together so conflicts are resolved on paper.
Our engineering group reviews drawings against the design and the code, and sends them to the design team for approval when required. We track each one in a log, with dates and status, so nothing is fabricated before it is approved.
On projects with specialty materials, we also show owners samples and details early so there are no surprises on installation day.
What to plan for
Build review time into your own approvals. If your designer or landlord must sign off, tell us how long they usually take, and we will order the process around it.
