Site plans
A site plan is a paper-based, or computer program that provides information about the location of site services, features and fixed objects. This information may include:
overhead, surface-level or underground services
natural or man-made features
contours, heights and distances.
Reading a site plan
You can use the information on the site plan to locate services and features at the actual work site, including underground services that may not be apparent on visual inspection of the site.
The site plan contains a lot of important information about your work area. By comparing the symbols on the plan with the plan legend, you can identify the various services and features that you may encounter on the job.
Using the site plan legend to locate objects and features
The legend below shows some of the symbols that you might find on a site plan. Click on the symbols or text in the legend to highlight the feature on the site plan.
Using scale and triangulation to work out distances
The plan scale shows distances on the plan in relation to actual site distances. The following example is for a scale of 1:500, meaning that one unit of distance on the plan is equal to 500 units of distance at the site.

Triangulation can be used to locate underground or hidden objects. Using the plan, measure out the distances between two visible fixed objects and the hidden object – crossing at the position of the hidden object. At the site, you will find the object at the point where the measurements cross. Look at the example on the right.

Why bother checking the site plan?
Who knows every inch of the grounds where they work? Here are just a few good reasons why you should check the site plan before every renovation job:
It may be a standard operation procedure. Fairway Views has a policy that you must check the site plan before every turf maintenance job.
The site plans may have been updated. You could find out the hard way about the underground services installed while you were in Bali.
The reticulation may have been rearranged. You could waste time looking for sprinklers that are no longer there, or fail to mark out a new one.
Your own peace of mind. It would be embarrassing if you started work on the wrong site!
The dimensions on a plan detail:
the length of marked out lines
the width of marked out lines
the angles of lines in relation to fixed objects or other lines
the shapes of marked out lines (square, rectangle, circle, semi-circle etc.)
To be able to mark out a playing surface accurately, you need to be able to read and understand the dimensions on a plan and transfer these dimensions to the surface you're marking out.
Have a look at the plan of a tennis court below. Drag the magnifying glass over sections of the map to view it in more detail. Take note of the information presented in the plan.
