The length of the properties boundaries are also shown. Site / Plot PlanĪnother item of interest on the site plan is the building finished floor elevations for the garage and floor plan. A dimension is shown indicating how far each corner of the building is in relationship to the property line or boundary. As you can see in the example site plan below, the driveway is shown entering off of the roadway. The site plan is drawn at a small scale so that everything fits on one page including the property boundaries. The north arrow is shown in the upper right hand corner of the below drawing. Depending on which hemisphere you’re in, this will determine which exposure get shade and how the sun hits various aspects of the structure, effecting its heat gain or loss. There will be a north arrow somewhere on the drawing providing the orientation of the building to North, this is especially important when doing heating and cooling loads. The yellow lines highlighted in the image below shows the property line, while the blue highlighted area shows the building area as it’s located on the property. The plot plan furnishes the essential data for laying out the building. Surveyors use the plot plan shown below to set up the corners and perimeter of the building using batter boards and the line stakes. The site planshows the survey marks, including the bench mark (BM), with the elevations and the grading requirements.
It shows the locations of proposed structures in outline. The site plan shows the contours, boundaries, roads, utilities, trees, structures, and other significant physical features on or near the construction site.
Site Plan (Plot Plan) – this shows how the building structure is situated on the plot of land it’s built upon. Key Plan – this shows you where in the building the current drawing is located in reference to other sections of the building. Location map shows where the property is located on a Google map or other source. Grading plan – shows the new and existing grading, the contour of the land. A revision number will be given that corresponds to clouded areas on the drawing where changes were made under this revision number. You might also find the original issue date and comments such as “Issued for Construction”. Revision Block will show any changes made to the drawings since they were issued.
The title block should be visible when the drawings are rolled up, that way you can tell without having to unroll them which project it is related to. Title blocks can run horizontally along the bottom of the page or vertically along the right edge of the drawing. Also included is a place for the individual responsible for the design and a date a place to record the progression and date of any milestones such as a plan check set, addendums and their date.
The main purpose of the title block is to identify the project and engineers involved in the design.

In this first chapter we will cover how to interpret the meaning of the various lines, references, sections and the general layout of construction drawings.ĭrawing List could include the following Trade Drawings All the drawings together will provide for a fully constructed project, covering everything from the structure to the mechanical systems. The larger and more complex the project, the more drawings will be contained within the set. Reading a set of construction drawings requires that you learn basic drafting guidelines and the symbols that are used to convey meaning, much like a traffic sign tells you what to expect up ahead.
