MEP drafting

We provide CAD drafting & BIM coordination services in the construction industry. We create 2D & 3D shop drawings and coordination drawings for MEP trades: duct, plumbing, HVAC piping, fire protection and electrical.

Our 3D BIM models are compatible with AutoDesk Suite and allow us to work with third parties in NavisWorks Manage for collision check and coordination.

Ductwork: Duct, equipment connected to duct, diffusers, registers, sleeves (if required) and elevations.

Plumbing & HVAC piping: Pipes types specification, sleeves (if required), invert and center elevations at each branch and at drains locations.

Fire protection: Pipes, sprinkler heads and center elevation at each branch.

Structure: Provided if the structure is complex or if required by customer. Include beams, joists and sleeves with elevations.

Who are we?

ShopDrawings.com is a CAD drafting company created under the name of Contractor Technical Services (CTS, Inc.) by David Fleming in 1980.

As Computer Aided Drafting (CAD) software became popular, we decided to create our own CAD program adapted for our specific needs, instead of using other popular CAD software. Our CAD interface allows us to draw our trades extremely fast and make quick editing.

When our clients require complex changes, we like to set up online meetings so they can view our editing in real-time and confirm that the new design is exactly what they want.

Today, we have the best of both worlds: fast editing through our CAD software with a final result as a 3D model. We also provide .DWG files compatible with AutoCAD for the convenience of our customers.

We are now located in Hagerstown, Maryland and provide CAD services countrywide.
