MEP Shop Drawings
At Bimacme, our MEP shop drawings are produced directly from coordinated Revit models. The geometry in the drawing is the geometry in the model.
What's Included
What MEP Shop Drawings Include
We produce shop drawings covering the full MEP scope. The specific content of each drawing depends on the trade and the project requirements:
Mechanical (HVAC) Shop Drawings
- Wet/dry/pre-action systems per BS EN 12845
- Head layouts with hydraulic zone boundaries
- Pipe sizing from design calculations
- Coverage zone validation in 3D model
Electrical Shop Drawings
- Detector & sounder layouts per BS 5839-1
- Control panel positions
- Cable route coordination
- Detection category compliance
Fire Protection Shop Drawings
- Damper at every rated penetration
- Smoke control ductwork & actuators
- Structural opening coordination
- Fire damper schedule production
Plumbing Shop Drawings
- Rising mains & landing valves
- Hose reel cabinet positions
- Coverage radii confirmed in model
- Inlet breeching coordination
Our MEP Shop Drawing Production Workflow
Coordinated Model Receipt & Review
We confirm that the Revit model has been through coordination sign-off before shop drawing production begins. Shop drawings produced from an uncoordinated model carry coordination risk into the drawings.
Drawing Sheet Setup
We establish the drawing sheet format, title block, and annotation standards required by the project or contractor. Scale, north point, grid references, and level datums are confirmed.
Plan & Section View Production
Coordinated views are extracted from the model with discipline-specific annotation. Duct sizes, pipe sizes, equipment tags, and support references are added from model data.
Isometric & Detail Views
For plant rooms, risers, and complex connection details, isometric and section views are produced to supplement plan drawings.
QA Review
Completed drawings are reviewed against the coordinated model to confirm consistency. Dimensions are spot-checked on critical runs. Discrepancies are corrected before issue.
Drawing Issue
Shop drawings are issued in PDF and DWG at the agreed revision. The drawing register is updated and drawings are transmitted through the agreed project document management system.
Frequently Asked Questions
Can you produce shop drawings if we already have a coordinated model from another party?
Yes. We regularly produce shop drawings from coordinated models delivered by other BIM consultants or MEP contractors. We review the model, confirm the LOD and coordination status, and produce drawings to your required format and scale. Where the model has residual coordination issues, we flag them before beginning drawing production.
What drawing formats do you deliver?
We deliver drawings as PDF for site use and construction records, and as AutoCAD DWG for contractor use and any downstream CAD work. We can also produce Revit sheets if required. Title block format, sheet size, and numbering convention are agreed at project outset.
Do your shop drawings include dimensions?
Yes. Shop drawings include all dimensions necessary for installation and fabrication. For ductwork, this includes overall dimensions, offset depths and widths, connection types, and access door positions. For pipework, dimensions cover pipe centreline levels, offset distances, and connection heights at equipment. For electrical containment, tray widths, depths, and support spacing are dimensioned.
Can you produce shop drawings for prefabricated MEP assemblies?
Yes. For off-site fabricated assemblies — duct spools, pipe modules, electrical racks — we produce fabrication drawings that include all information required for workshop manufacture: overall dimensions, connection point geometry, material specification, and assembly sequence. These are produced at LOD 400 from the coordinated model.
How do you manage drawing revisions during construction?
change, RFI response, or site instruction affects a coordinated zone, we update the model, recheck affected coordination, and issue revised drawings with a new revision suffix. The revision cloud and change note are added to each affected sheet. The drawing register is updated and transmitted through the project document management system.
