MEP design support from load calculation to coordination
MEP systems take up a large share of a building's budget and most of its coordination effort. Our MEP engineering services cover the tasks that sit around the engineer's design decisions: calculating loads, preparing permit drawings, documenting energy compliance and coordinating systems in 3D before installation.
This category focuses on design support and compliance. For pure drafting of an engineer's design, see MEP drafting, HVAC drafting and electrical drafting in our CAD services.

MEP BIM Clash DetectionRevit MEP coordination models, Navisworks clash detection and the combined services, sleeve and hanger drawings trades install from.
Solar Design ServicesPermit-ready PV plan sets: site and roof layouts, single-line diagrams, attachment details, labels and calculations – for residential and commercial solar.What to send for an MEP quote
- Architectural floor plans, sections and elevations.
- Construction details: walls, roof, windows and insulation (for loads and energy).
- Equipment selections or the engineer's design intent.
- Your jurisdiction and the code editions it uses.
Most residential MEP packages – load calculations, permit drawings, PV plan sets – can be quoted within a few hours from these documents.

Engineering responsibility: we prepare drawings, models and calculations as a drafting and design-support team. Where the law in your state, province or council requires it, the final design must be reviewed, signed and sealed by the licensed engineer or architect of record for the project. We work to their markups and do not stamp drawings ourselves.
How we deliver MEP engineering services
- 1Send your files
Upload sketches, PDFs, markups, photos, scans or a model through the quote form. Tell us the standard (US, UK, Canada or Australia) and the deadline.
- 2Fixed quote in hours
We review the scope and reply with a fixed price, the deliverables list and a delivery date. Nothing starts until you approve it.
- 3Drafting & modeling
Your project is drawn in AutoCAD, Revit, Civil 3D, SolidWorks or the software you use, on your title block, layers and templates.
- 4QA check
A second drafter checks dimensions, annotations, layer standards, sheet numbering and cross-references against your input before anything is sent.
- 5Delivery & revisions
You receive native files plus PDFs. Comments come back as markups and we revise them quickly until the set matches the brief.
