BIM vs CAD explained: compare features, costs, clash detection, and workflows to choose the right technology for your construction project.
What Is CAD Drafting Outsourcing and When Does It Make Sense for UK and European Firms?
CAD drafting outsourcing means hiring an external specialist team to produce, convert or update technical drawings for you, instead of employing in-house drafters. It makes sense for UK and European firms when workloads fluctuate, when hiring and retaining drafters is costly or slow, or when you need fast, accurate drawings without adding permanent headcount.
Computer-aided design (CAD) drafting is the process of turning concepts, sketches, markups and site data into precise technical drawings. These drawings guide design approval, tendering, manufacturing and construction.
Outsourcing hands part or all of that work to a dedicated drafting partner. You send your inputs, such as hand sketches, PDFs, scans, markups or design briefs. The partner returns finished drawings in the format you specify, ready for your review and sign-off. Your firm keeps design responsibility and client relationships, while the production work is handled by a specialist team.
Most outsourcing partners cover a wide range of drafting and modelling work. Typical services include:
Salaries, recruitment fees, software licences, training and office space add up quickly for in-house drafting teams. Outsourcing converts much of that fixed cost into a flexible, pay-for-what-you-use cost. Offshore teams, such as those in India, can often deliver the same standard of drawings at a lower overall cost.
Workloads in architecture, engineering and construction rarely run evenly. A tender deadline or a large project can overwhelm a small team. An outsourced partner lets you scale up for a busy period and scale back afterwards, without hiring or redundancy.
Skilled CAD and BIM technicians are in demand across the UK and Europe. An outsourcing partner gives you immediate access to drafters experienced in AutoCAD, Revit, 3D modelling and MEP coordination, without a long recruitment process.
When you send work at the end of your day, an offshore team can progress it while you are offline. You often start the next morning with drawings ready for review, which shortens project timelines.
Outsourcing routine production lets your senior designers and engineers focus on design decisions, coordination and client communication, which is where they add most value.
Outsourcing is usually a strong fit if:
Outsourcing is not always the best answer. Consider keeping work in-house when:
A phased approach helps. Many firms start by outsourcing one type of work, such as CAD conversion, and expand once they are confident in the results.
Erasmus CAD Solutions is a Bengaluru-based engineering services firm, established in 2018, providing CAD drafting, 3D modelling, BIM, MEP drafting, CAD conversion and related services to clients worldwide. Our team works to your drawing standards and delivers in the file formats you need, so our output fits into your workflow.
If you would like to try outsourcing on a small project first, get in touch and share a sample drawing for a no-obligation discussion.
It is the practice of hiring an external team to create, convert or update technical drawings, so you do not need to employ all of that capacity in-house.
For many firms, yes. You avoid fixed costs such as salaries, software licences and training, and pay only for the work you need. The saving depends on your volume and the complexity of the work.
Yes, provided you share your standards, templates and examples at the start. A good partner works to your layer conventions, title blocks and file naming rules.
Use a non-disclosure agreement, agree secure file-sharing methods, and clarify who owns the final files. Reputable partners will be familiar with these requests.
Common deliverables include DWG, DXF, RVT and PDF. Confirm the formats you need before the project starts.
Most firms can begin with a small pilot project quickly, often within days, once the brief and sample files are shared.
