AI image by LocalRankMost renovation, fit-out and engineering jobs reach a point where someone has to turn sketches, site measurements or old paper plans into clean, editable drawings. That is the work of a CAD drafting service, and in Singapore the field runs from small drawing studios to BIM consultancies and civil engineering firms. This list covers eight providers that publish drafting, conversion or modelling work on their own websites. Descriptions come from what each firm says about itself, so treat them as a starting point. Check the file formats you need, ask for sample drawings, and request a written scope from two or three firms before you commit to one.
1. CAD Drafting Singapore
CAD Drafting Singapore is a Woodlands-based drawing and BIM practice whose website lists an unusually broad menu. Under 2D work it names architectural, MEP (M&E), shop and submission drawings, while its as-built group covers 2D as-built drawings, on-site measurement, 3D laser scanning and scan-to-BIM. The site says it can convert existing material into AutoCAD files, Revit projects (.rvt) and Revit families (.rfa), and it also lists BIM modelling, rendering, walkthroughs, physical scale models and outsourced contract drafting. It names AutoCAD and Revit among its tools and says it runs AutoCAD and BIM training too. Its contact page gives weekday office hours and a quote form for sending project details, which is the route for scoping a job.
2. Bimeco
Bimeco Pte Ltd, based in the Braddell area, positions itself as a BIM team that architects, contractors and building owners can call on as needed. For drafting buyers, the relevant page on its site describes 2D CAD drafting for architectural, structural, electrical and piping projects, plus shop drawings produced from coordinated BIM models. It also lists CAD-to-BIM conversion, standard CAD templates with consistent layers and annotation styles, BIM coordination and documentation. Wider services on its site include scan to BIM, drone survey and Revit work, and it says it supports Revit, ArchiCAD, Tekla and IFC. The firm also advertises staffing options, such as hiring Revit freelancers or BIM managers, for teams that want extra hands rather than a finished package.
3. Bimage Consulting
Bimage Consulting lists its Singapore headquarters in the Redhill area, alongside offices in several other countries, and describes itself as a BIM consultancy that also takes on modelling work. Its modelling services, as listed on its website, include converting 2D drawings into 3D models, shop drawings, as-built drawings, clash coordination, subcontractor coordination models, quantity generation and 4D simulation. The site says it has delivered modelling services for about eight years. Alongside production work it offers consulting, BIM implementation support and training programmes, and it develops Revit plugins and other software tools. That mix may suit an owner or contractor who wants drawings produced and also wants help setting up BIM workflows inside the team.
4. CAD Service Singapore
CAD Service Singapore is a compact drafting provider based in the Rochor area, and its homepage keeps the offer simple. It lists 2D CAD drafting covering plans, elevations, sections, details, layouts, shop drawings and technical drafting, along with 3D CAD modelling for product ideas, design coordination and visualisation. A third strand is CAD conversion, where the site says PDFs, sketches, scans and redlines can be turned into editable CAD files. Its service pages also mention as-built drawing updates and redline revisions, which suits owners with an existing drawing set that needs amending. The website shows a phone number and a WhatsApp number as the way to start a conversation, and no email address is printed on the homepage.
5. DECS
DECS Pte Ltd, which also appears on its site as Dilningecs, presents itself as an independent civil and infrastructure engineering consultancy, with CAD drafting for civil and structural projects as one of its listed services. Others on the same page include civil engineering design and structural detailing, geotechnical design and detailing, construction site supervision and remote staffing. It lists an office near Circular Road in central Singapore. The site states that its deliverables follow Singapore Standards and relevant agency requirements and go through internal technical review before issue; that is the firm's own statement, so ask what it covers. The service suits contractors and developers who want drawings prepared by an engineering team rather than a drawing-only shop.

6. 3D Specialist
3D Specialist is a Henderson-based business best known for 3D printing, and it earns a place here for its mechanical and product-side modelling. Its website describes a 3D modelling and CAD service covering concept-to-production CAD, parametric models, design-for-manufacture and additive review, generative design and topology optimisation. It names SolidWorks and Fusion 360 and lists STEP, STL and DXF among the files it delivers. Under its scanning service the site also describes reverse engineering legacy parts and converting scan data into CAD. The site does not list a standalone building-drawing service, so this is a match for product designers, makers and engineers needing part models, rather than for architectural plan sets or submission drawings.
7. S-CAD
S-CAD is a drawing-focused service that states on its website that it has operated since 2011, with a listed address in the Playfair Road area. Its service list is oriented to construction and fit-out trades, naming architectural drawings, civil and structural drawings, interior design drawings, steel and glazing drawings, aluminium cladding drawings, curtain wall drawings, GFRC drawings and water-proofing drawings. That specialist spread could suit facade contractors, fabricators and designers who need package drawings for particular trades. The site links pages for sample drawings and an architecture blog, and it shows an enquiry email and a phone number. It does not publish a company registration name, so ask for the contracting entity when you request a scope.

8. Rui Xin BIM Consulting
Rui Xin BIM Consulting Pte Ltd operates from the Robinson Road business district and describes itself as a BIM engineering and construction subcontractor. For drafting buyers, its website lists 2D CAD drafting and CAD-to-BIM conversion alongside 3D BIM modelling, with on-site or off-site BIM manager and coordinator roles, BIM execution plans and 3D clash coordination. Beyond that, it lists 4D construction sequencing, 5D quantity take-off, 6D sustainability data, scan-to-BIM, VR walkthroughs, digital twin mapping and software training. The site invites visitors to email their 2D drawings and requirements to receive a quote, and it shows a phone and WhatsApp number. Its offer reads as aimed at project teams more than one-off home jobs.

How to choose
- Start with the deliverable, not the firm. Decide whether you need editable DWG files, Revit models, PDF sets or drawings in a specific submission format, and say so in your first message. Providers describe different strengths, so a firm strong in BIM may not be the natural fit for simple 2D plan updates.
- Match the discipline. Architectural plans, MEP coordination, civil and structural detailing, trade packages and mechanical part models all draw on different skills. Read each website's service list for the discipline you need, and ask for a sample drawing in that discipline before sending your own confidential files across.
- Be clear about the source material. Conversion jobs depend on what you hand over, whether scanned paper plans, PDFs, hand sketches or site measurements. Ask whether the firm measures on site or scans itself, or only works from files you supply, because that changes who is responsible for accuracy.
- Ask about review and revisions. A drawing set usually changes after the first issue, so find out how many rounds of mark-ups are expected, how the firm checks its own work, and how it names files and versions. Get the answers in writing along with the scope and turnaround before work begins.
- Check the paperwork and the claims. If a firm cites approvals, standards or professional sign-off, ask exactly what they cover and who holds them, and verify with the issuing body. Drafting alone rarely replaces a qualified person's endorsement on authority submissions. Confirm the contracting company name, ownership of the drawings and how files are kept confidential.
