The Demolition Drawing
The demolition plan in a set of construction drawings shows which items in the existing space are to be removed. As well it shows which items are to remain.
The items to be removed are often existing walls, doors and frames and fixtures.
In some cases, fixtures or millwork are removed temporarily and then relocated once the new construction is completed. This is typical for remodel or renovation projects.
A plan is drawn of the existing layout of the space for the project.
This includes all items, such as walls, fixtures, furniture, plumbing fixtures, electrical panels, etc.
The items to be removed or relocated are indicated on this plan with dotted or dashed lines.
Notes are added directly to the plan or listed as numbered keynotes in a legend. When coded notes are used, they are added to the areas of the plan, which they reference.
Notes are important as they specifically state what is required of the general contractor or demolition contractor. For example, a note may state that a wall is to be removed and disposed of properly. Or that a chair rail is to be removed temporarily, and reinstalled in the same location after the new finish is applied to the wall.
A separate plan, referred to as a construction plan or partition plan, is drawn to indicate the new layout of the space.
The contractor typically reads the demolition plan in conjunction with the plan(s) for new construction.
In cases where minimal removal work is required, the demo work is indicated on the new partition plan. It is not necessary to produce a whole drawing sheet only to indicate the removal of one or two items. The items to be removed are drawn as dotted or dashed lines and the appropriate notes are added.
The demo sheet typically has a floor plan, drawing notes or keynotes and general notes.
The size of the drawing sheet follows the format of the set of construction drawings.
A reflected ceiling demo plan or a relevant elevation is included when necessary to convey specific details regarding the removal of items. The more information provided graphically with specific notes will ensures accurate pricing and that the removal work is clearly indicated.
The project will run smoothly for everyone involved.

Each project is unique and notes are specific to each project.
The following is an example of a demo plan with notes added directly to the plan.
The keynote system is typically used for projects, which require extensive removal work and many written notes to cover all aspects. A plan with keynotes is easier to read, as the notes are listed in a legend rather than directly on the plan.
A keynote, repeated several times on a plan is quickly adjusted, when required. It is listed only once in the legend and therefore the change needs only to be done once.
Whereas when the same note is repeated many times directly on the plan, it will need to be adjusted many times.
Below is an example of a plan with keynotes added.
The following is an example of the coded notes for the plan above.

General notes provide information covering the overall project. These notes outline conditions and requirements; a contractor must apply to a specific project. An example of one of these notes is:
The general contractor and/or demolition contractor must visit and review the site to be familiar with the scope of the project prior to submitting a bid.
Depending on the type and size of a project, the amount of general notes will vary.
The following is an example of some typical general notes.
These are an example only and should not be copied verbatim.
Each project is unique. General notes should relate to the specific project.
Interior designers and architects produce the demolition drawing, when it is necessary, for a project.
It is considered to be a part of the overall design and set of construction drawings.
An application for a building permit will include this drawing sheet in the set. Code compliance is required.
For some larger projects a demolition permit is applied for before the set of construction drawings for new work are completed. The demo plans are submitted separately. Once the permit is issued for removal work, the work can begin.
Meanwhile, the construction drawing set is completed and submitted for a building permit. By the time the permit is issued for new construction, the site is often clean and ready for the start of the new work.
Whatever the process, demolition takes place before new construction begins on the site.
