About us

ShopDrawings.com was created under the name of Contractor Technical Services (CTS, Inc.) by David Fleming in the mid-1980s.

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 with slow drawing processes and never-ending pull down menus.

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

We are now located in Hagerstown, Maryland.

MEP trades

We provide drawings for duct, electrical, HVAC piping, plumbing and sprinklers. We always include: floor plans, column lines, ceilings, lights, sizes and dimensioning to the grid for each trade.

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

Plumbing & HVAC piping: Pipes specifying the type of pipe (CW, VENT, SAN, ST, etc.), sleeves (if required), invert and center elevations at each branch and at drains locations.

Sprinklers: 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.
