Condition (Amber) surveys

If you are looking at more than one route, or working more widely on an area basis, you may wish to collect information about the current condition of all the routes before deciding where to focus your efforts. This is effectively a reconnaissance stage and you will need a consistent method of collecting data that can be compared between routes. This information can then be used to decide how much work is necessary, whether surveyed routes can be repaired, upgraded or constructed, and should help to inform priorities about which routes would provide the greatest benefit for the investment. You may also be able to make an indicative estimate of costs to repair, upgrade or construct each route. An amber survey is used to collect this information, which will be a mix of measurement, descriptions and assessments about the routes.

Amber surveys measure the condition of routes using a series of more than 30 measurements for each section of the route. The measurements collected cover the physical characteristics of the route such as slope, width and other real figures, along with assessments of condition, drainage and dynamism (how quickly change is likely to occur).

The amber survey method is designed to be fairly quick and, if required, more detailed information can be collected later using the red survey method. Try not to get bogged down in too much detail, there will be variations along a route and it is not necessary to capture everything at this stage.

Although this next section might appear quite daunting, the amber survey methodology is well structured and reasonably intuitive. It provides four types of data:
