What Happens Between Concept and Construction Drawings?
Author: Rick Ovenden
If you’ve approved your concept drawings, it’s easy to assume the next step is simply pressing print on the construction drawings.
In reality, that’s where a significant amount of work begins.
One of the most common questions we hear is, “How long until the construction drawings are ready?”
It’s a fair question. From the outside, it can look like we’re just taking an approved design and adding more detail.
But between concept approval and issuing construction drawings, there’s a lot happening behind the scenes. Much of it involves working with other people, checking information, resolving design details and making sure everything is coordinated before anyone starts building.
This stage is often one of the most important parts of the entire project.
The Concept Isn’t the Final Design
Concept drawings are exactly that.
They confirm the overall direction of the project, including things like the building size, layout, functionality and general arrangement.
Construction drawings are different.
They’re the documents your builder, fabricators and installers rely on actually to build the project. Every structural member, connection, level, dimension and detail needs to be accurate.
That level of information doesn’t exist on day one.
It has to be developed.
Every Project Depends on Information
One thing many people don’t realise is that our drafting team doesn’t work in isolation.
Before we can complete construction drawings, we often need information from multiple stakeholders.
Depending on the project, that may include:
- Engineers
- Architects
- Builders
- Surveyors
- Certifiers
- Clients
- Consultants
- Suppliers
- Internal design teams
Sometimes we’re waiting on engineering calculations.
Sometimes dimensions need to be confirmed.
Sometimes another consultant changes part of the design, which means several drawing packages also need updating.
Every piece of information affects something else.
Coordination Matters
Producing construction drawings isn’t simply drafting.
It’s coordination.
Our role is to make sure every piece of information works together before we release the drawings.
That means checking that:
- Structural layouts align with architectural requirements.
- Door openings, services and access all work together.
- Steel members and connections are correctly detailed.
- Building dimensions remain consistent across every drawing.
- Any design changes have been carried through the complete drawing set.
Finding an issue on paper is much easier than finding it on site.
That’s why this stage is so important.
It’s Rarely a Straight Line
No two projects follow exactly the same path.
Questions come up.
Design decisions evolve.
Information arrives at different times.
Sometimes approvals take longer than expected. Other times a change to one part of the building creates several updates elsewhere.
That doesn’t mean the project has stopped.
It usually means people are working together to make sure everything is right before construction begins.
Accuracy Is More Important Than Speed
We understand that everyone is keen to get on site.
Our team is too.
But rushing construction drawings often creates bigger problems later.
A missing detail or incorrect dimension can result in delays, additional costs or unnecessary rework during construction.
Taking the time to properly coordinate the documentation helps reduce those risks and gives everyone greater confidence once construction begins.
What We’re Really Doing Behind the Scenes
While it might look like drawings are simply “being drafted”, our team is often:
- Reviewing new information from multiple stakeholders.
- Coordinating design updates across different disciplines.
- Checking dimensions and structural details.
- Resolving clashes before construction.
- Programming and modelling the building.
- Preparing accurate documentation for manufacturing and construction.
- Completing quality assurance checks before issue.
It’s detailed work, but it’s what helps projects run more smoothly once they’re on site.
Good Construction Starts Long Before Site
One of the biggest misconceptions in construction is that progress only happens when you can see it.
In reality, some of the most valuable work happens long before the first piece of steel arrives.
The time between concept and construction drawings is where ideas become coordinated, buildable solutions.
When everyone works together and the details are resolved properly, construction becomes more predictable, efficient and far less stressful for everyone involved.
At TechSpan, we see this stage as one of the most important investments in the success of your project.
