In the drawing office, the conversation about technical drafting costs rarely starts with a rate. It starts with a desk full of piles: a revision set that has been waiting for two months, detail drawings nobody picks up because live projects take priority, and an as-built dossier that everyone knows will become a problem.
The drafters are fully booked, the schedule slips, and only when the deadline comes into view does the question become urgent. At that point, it is no longer about the cheapest hour, but about what it costs when the drawing is late.
That is usually exactly where we come in. The trigger is almost always capacity: too little time, too few drafters, or a peak the in-house team cannot handle. We draft and model, in high volumes and with a lot of repetition. Below, we explain where the costs of this work really come from and where we bring them down. We do not mention amounts, because the setup differs per job and a figure on its own gives you nothing to go on.

Parametric working and what it saves in costs
The biggest saving does not come from a lower rate but from fewer actions. We build parametric Revit families, in other words smart components. A component like this adapts to a new situation or a different size: the drafter creates it once and then places it anywhere, without drawing it again. When the component changes, the linked material schedule updates automatically. That saves not only drafting time but also checking afterwards, because nobody has to compare by hand whether the schedule still matches the model.
The clearest example from our work comes from greenhouse construction. Companies there often draft in AutoCAD, and AutoCAD is not smart at building up parts such as valves in piping systems. Anyone who needs a valve in 90 and in 110 redraws it by hand every time, on every diagram and in every revision. With a smart family, it is in place in a single action. In work like this, it saves at least seventy per cent of the time. We can clean up existing families and templates or build them from scratch; which is wiser depends on the state of the existing set.
If it is very messy, rebuilding is sometimes faster than repairing. We would rather make that call up front than halfway through, because that is exactly when costs get out of hand. We present our findings with the reasoning behind them and the client decides. Everything we build remains their property afterwards, so they stay in control of their own library.
Software and formats in which we deliver technical drafting
Our main software is Revit, AutoCAD and Rhino. We also work in Inventor and Grasshopper, and to a limited extent in Dynamo and Vault. We always run the latest versions, in our own environment and with our own licences. That has a practical side that shows up on the bill: you do not have to set up a workstation, free up a licence or arrange access to your internal environment. Your IT administrators keep their hands free and we can start as soon as the files are in.
We process and deliver DXF, DWG, Revit formats and STEP files, and in practice any common CAD format. That is not a minor detail, because time gets lost precisely in the handover between packages. A model that sits neatly in Revit but picks up the wrong layer structure on DWG export creates manual work on the other side that someone has to redo at every delivery. That is why we agree in advance what the export should look like. We also work to the client's standard and drawing conventions, which we receive from them.
If nothing has been documented, we derive the standard from the supplied material and present our assumptions before we press on. Aligning with what already exists costs one conversation at the start and saves a great deal of correction afterwards. In this line of work, that is the cheapest time anyone can invest. For standalone drafting work, files simply go back and forth by email, and on larger projects such as greenhouse construction projects we work with software that the client can log into to follow the project.
No ongoing payroll costs and no idle staff once the peak is over. If one of our people is off sick or on holiday, we replace them and the work simply carries on.
What we deliver and how that shapes technical drafting costs
We deliver 2D drafting and, where needed, 3D modelling, as-built drawings and revisions. In practice, that means floor plans, elevations, sections, detail drawings, piping diagrams and the components used to build them. What we do not do is engineering: no calculations, no structural advice and no permit procedures. That boundary matters for the cost question, because it determines where our hours do and do not go. Most of our jobs involve high-volume work with a lot of repetition, and that is exactly where the price per drawing can be made predictable. With revision work, the scope depends heavily on the state of the supplied material. A clean DWG set with a consistent layer structure is quick to update. A dossier that was printed incorrectly and partly amended by hand requires investigation before a single line changes.
We handled a dossier like that for Firefly and sorted it out ourselves instead of calling the client constantly, and then delivered it properly all the same. That investigation is included in the hours, but it does not push work back to the client. We deliver in stages, gather feedback and carry on. That keeps it visible what has been done and where the time is going, which is exactly what a project lead needs to keep an eye on their own budget. We match the rhythm of our meetings to that: every two days when it needs to move fast, weekly otherwise. That way, the scope of the work stays visible before hours go into things nobody had anticipated.
Three review layers that reduce the cost of rework
The most expensive drafting work is the work that has to be redone. That is why nothing leaves our hands without being checked. A drafter draws, a second team member checks that work, Sam then checks it as team leader, and Barry, our project manager, carries out the final review. As a result, the number of errors in practice is minimal. Those four pairs of eyes cost us time, but they prevent the kind of error that only surfaces on site or during fabrication, when the bill is of a different order entirely.
Sam, our team leader, has more than fifteen years of background in architecture, worked in Iran for seven years, ran his own design firm in the Netherlands and still works as an engineer.
So he looks not only at the lines but also at the logic behind them. Everyone who works for us has more than ten years of CAD experience, and the core of the team has around twenty-five years of experience combined. We hold no certifications and make no promises about them; what we do have is a fixed way of working and people who have been in the trade long enough to know where things go wrong.
Besides the checks, rhythm helps. We deliver in stages, gather feedback and make adjustments, every two days on a tight schedule and weekly otherwise. Errors spotted early cost minutes; the same errors at the end cost days. We deliberately steer by that ratio. You also have one fixed point of contact, so a comment does not have to pass through three people before anything is done with it.
