MEP Shop Drawings & BIM Coordination

CAD drafting services
for Contractors

We specialize in drafting and coordinating MEP trades: Shop Drawings / Fabrication Drawings and BIM coordination of Ductwork, HVAC piping, Plumbing, Fire Protection and Electrical.

We also offer CAD drafting services for raised access floors, millwork and glasswork.

Whether your project is a new construction, a renovation or simply requires as-builts, we’ve got you covered.

Why getting Shop Drawings matter

Contract Drawings are diagrammatic and rarely contain all the information your team needs for fabrication and installation. Many conflicts are overlooked, the most common ones being: insufficient ceiling space to fit multiple trades and overlooking the slopes of pipes for the coordination.

Instead of working with Value Engineering, get Shop Drawings to coordinate trades efficiently, send RFIs early in the construction phase to avoid construction delays, prevent costly field adjustments and save on pre-fabrication costs. Eliminate the guesswork: Give your shop and field crew the exact information they need.

Our MEP coordination drawings include: identification of trades, trades sizes, elevations, units per approved submittals, duct sheet metal length (TDC, S&D), reflected ceilings and diffusers per RCP layout, wall and floor sleeves when requested and more.

Full MEP coordination: No clashes left behind

When designated responsible for the full MEP coordination of a project, we have the capability to resolve the majority of trade clashes internally.

This eliminates the need for coordination meetings, which speeds up the overall coordination of a project and allows us to quickly deliver coordinated MEP drawings.

Avoid costly
field fixes

Contract drawings are meant to be diagrammatic — they don’t provide the full level of detail needed to fabricate and install without issues. That’s where shop drawings and BIM coordination make the difference. We help contractors bridge the gap by providing:

• Clear, buildable drawings that turn conceptual documents into practical details your crew can trust.
• Early conflict detection so clashes between trades are resolved on paper, not in the field.
• Support for prefabrication that speeds up installation and reduces labor costs.
• Accurate coordination across trades, minimizing RFIs and last-minute changes.
• Smooth project delivery with fewer delays, fewer change orders, and easier approvals.

Fast changes,
Real-Time Editing

When our clients require complex changes or need specific elevations for their MEP trades, we like to set up online meetings so they can view our editing in real-time and confirm that it is the design they exactly want.

Our drafting method is so quick and our team so efficient, that we often make changes before our customers finish describing the change they want to see!

Lead BIM meetings
with Confidence

Our policy is to model all projects to ensure accuracy, economy and efficiency in its design. As a result, we generate 3D models for all our trades to ensure a seamless and clash-free project.

We also offer online BIM meeting leading services: clash detection across all trades, clash assignments to each specific trade and verification of successful clash resolution.
