PRODUCT 1. The ROCKS Framework is based on five key concepts that characterize the system, and provide the foundation to achieve its objective and intended outputs.

• The first concept seeks to systematically classify the different road work types and predominant work activities in order to be able to organize them and match them with typical civil works contracts. The road works have been classified in two categories: Preservation and Development. The details on road work classes, road work types and predominant work activities are presented in Figure 4 and 5. Display or download in MS-Excel the ROCKS Road Works Classification (work types and predominant work activities) dated 09/09/02;

• the second, defines a shared concept of unit cost as the fundamental cost element, and depending on the type of work suggests to use $/km, or $/m2;

• the third concept, establishes a minimum set of data requirements that is generally available in any country and that allows the system to work;

• the fourth concept seeks to add flexibility to the system by defining a set of highly recommended data set, and a series of optional data that allow the users to select the levels of detail or criteria to be used and adapt the system to their needs and data available; and

• the fifth concept suggests to collect the data on any currency and reference date, but to convert all data to a single currency and a single reference year to allow for data comparisons.
