RAMM allows you to describe your road network both linearly and geospatially. Each road can be divided into any number of sections. Normally this would be from intersection to intersection or based on factors such as width and traffic volumes.
Long highways can be split by reference stations and established route positions. This enables a third level of segmentation.

Road sections are categorised based on a number of standard groupings supplied with the system and a number of user defined categories. Each road section can also record usage information such as traffic counts, traffic estimates, as well as loading information such as percentage heavies, ESAs and so on.
The network can also be split into security zones so that restrictions can be placed on access to certain parts of the network. These splits can be physical, such as by suburb, or logical such as urban or rural.
RAMM comes with standard asset types that can be described on your network. All asset types have industry standard parameters already set up. There is a wide variety to meet almost every asset manager’s requirements.
If you manage assets not on the list you can set up your own User Defined Assets (UDTs).

The standard RAMM Asset set includes:
The Condition of an asset describes its fitness or readiness for use. RAMM comes with many standard ways of determining and recording the Condition of your network assets.
Additionally you can describe your own methods of assessing the Condition of an asset.

The standard set includes:
Asset Valuation defines rules for the valuation of the road network and the calculation of network asset replacement costs. Local government authorities are required to fund the depreciation of their infrastructure assets.
To do this, the current Replacement Cost (RC) must be determined for those assets.

Using this Asset Valuation information, together with details of Condition and methodologies for depreciation, the current and projected Depreciated Replacement Cost (DRC) can be determined. This DRC can be used to determine the funding required. Valuing assets also assists local government bodies with other planning activities, including:
An Assessment is the record of an inspection of an asset. You use Assessments for a number of reasons including to record the Condition of an asset or its associated likelihood and consequences of failure. In simple terms – the risks.
From this data, an overall risk value can be estimated.

Assessments can be performed using Pocket RAMM. For this you use Assessment templates that you have created yourself. For further information watch Setting Up Assessment and Assessments in RAMM Patrol.
You can also use a paper-based system in which worksheets are created and then used for Assessment inspections. The results are then entered into the Assessment system. Inspection schedules are generated giving you advance warning of Assessments that are due.
This enables you to calculate weighting for condition, risk likelihood or risk consequence. The calculations conform to the NAMS Standard Condition Categories (for Condition) or the Standards New Zealand document Guidelines for Managing Risk HB 143:1999 (for Risk Likelihood and Risk Consequence).
Let’s take the example of Assessment for a bridge. You may simply wish to know the Condition of a bridge over a period of time. You can build a worksheet template, create a worksheet and perform regular Assessments to do just that. On the other hand, you may like to know which bridges in your road network are more likely to fail or have a high economic consequence when they do fail. For this sort of Assessment you’d build a worksheet template for risk likelihood and/or consequence and perform the Assessment accordingly.
The detailed picture of your road network that emerges helps you plan for the future with greater accuracy and certainty.
FWP is used to manage medium to long term (up to 20 years) maintenance programmes. FWP assists asset engineers to meet NZTA’s philosophies and expectations for the management of assets as described in the State Highway Asset Management Manual (SHAMM).
Road Controlling Authorities (RCAs) will also find FWP useful for effective road asset management.

RAMM FWP is designed to store pavement Treatment Length information at project level for a period of up to 20 years. This is beneficial as it allows you to plan your budgets for the entire network on a yearly basis and to provide costings for that period, while projecting costings for future years.
For example, you could plan to carry out a grade 3/5 two coat reseal on SH 3 RS 269 RP 0.100 – 2.540 in six years’ time. Below is an overview of the process for development of a robust Forward Work Programme.
There are more features – too many to list on this page. The following are ones you might find useful. You can import data into RAMM, Export data from RAMM, query and report with SQL, Map assets, use the Bylaw registry for speed zones and parking, use Crash data from NZTA, use the Treatment Selection Algorithm and see a 3D representation of your pavements.
