There is a real importance in using the right drawings on any project

There are several different kinds of drawings used in a refurbishment project. So it’s important to understand the difference.

These will depend on the size of your project

If it is a small job the original construction drawings may be the only set used. Any variations once    agreed can just be marked on them. But if your project is large or complex you may wish to have new ones printed every time a variation is agreed. Therefore its important to always check you are using the right drawings

Planning a project

When you are initially planning a Project the Architect will produce a set of drawings and internal details may be indicative only. They may show a general layout for sockets and lights or a standard design for the  kitchen. These are called planning drawings.

Once you start planning the layout in detail you may decide to move certain things, and once you have finalised your design and had these approved by building control these are the drawings that you will be sending out to contractors in a tender pack.

Once the contractors have priced against these and you have accepted their tenders these will now become the construction drawings. These drawings are sometimes called the Contract drawings

Once the contract has started and you decide you want changes made new drawings may be produced and these will be called the revised drawings. These may be revised several times and will be called Rev 1, Rev 2,  Rev 3 and so on

This is where problems may occur

You must ensure that your builder is working to the latest revision. It’s no good just agreeing variations with the Architect and not communicating this to the people carrying out the work. It can further complicate things if you have employed individual tradesmen. You may have decided to change the layout of the kitchen in revision 3 and issued that set to the kitchen fitter. But the electrician may still be working to revision 2

Using a design and build contract

If you have signed a design and build contract with your builder. This means that he will take responsibility for the design of certain elements of the project. These contracts are sometimes used so a project can start quickly. As a result all the drawings may not be in place when work begins.

In this case when the job is finished he will give you a set of drawings that are called “As built” drawings or “Red line “ drawings. These will show details of anything that has been added to or changed from the original drawings

Working to the wrong drawings is a common occurrence on jobs. This has the potential to cause major disruption and substantial extra costs. It’s something that can easily be avoided
