Marlborough District Council Roading Assets - Activity Management Plan 2015 - 2018 SECTION 1 EXECUTIVE SUMMARY 1.5.3 Asset Management Systems The following systems are employed in managing the road assets; 1.5.3.1 RAMM – Roading Asset Register The roading network physical data is contained within the Marlborough District Council RAMM (Road Assessment and Maintenance Management) database. This information is continually updated as roads are constructed, sealed, resealed or rehabilitated, structures built and new traffic signs installed. In addition RAMM also stores condition information. The information which MDC currently collects in terms of condition on the: Sealed Network is; Roughness – summarised at 100m intervals for every road section. Condition rating – capturing of faults by way of manual inspection at a 10% sample rate on every treatment length. Form of fault recorded – shoving, rutting, potholes, cracking, drainage fault in terms of ineffective surface water channel, broken channel. High speed data info (roughness) on all sealed roads. Unsealed Network; Roughness – not currently done but selected sections to be monitored as part of proposed new LoS measure, summarised at 100m intervals. This is only some of many inputs used to generate a physical works programme to request funding and maintain levels of service. Further condition information that can be gathered and stored in RAMM is; Unsealed Network; Rutting, potholes, shoving, metal build up. Footpath Rating; Condition rated on a scale 1-5. 1 being excellent and five being replace immediately. 1.5.3.2 Pavement Performance Model (dTIMs) The Treatment Selection Algorithm (TSA) available in RAMM was originally used by Council to determine the immediate (or short term) and annual maintenance works programme for the road network. The RAMM TSA did not have a predictive modelling capability and did not consider the life cycle analysis for optimisation purposes. Council has used the Deighton’s Total Infrastructure Management System (dTIMs) system with predictive modelling functionality since 2003/04. The dTIMs system - a technical and economic appraisal tool, approved by the NZTA and introduced by Road Information Management System (RIMS Group, can be used for long1) term as well as short term planning of the road maintenance works. The dTIMs modelling is used to confirm the level of renewal investments are adequate to prevent consumption of the asset. The results are also an important input into the development of the Forward Works Programme. Pavement performance modelling is done utilising the Deighton’s d’Tims model in a number of ways; firstly to help in the long term planning of pavement and surfacing treatments on the network, secondly to help understand the impacts of the confirmed forward work programme in terms of condition outcome, and thirdly to test the outcomes of differing budgets in terms of the long term condition of the network. A pavement deterioration model has been developed for the network utilising the dTIMS software package and the HDM-4 deterioration model. 1.5.3.3 Service Request / Incoming Communications Council maintains a customer request database. This database is used to log calls from the customers and stake holders. The Council logs requests and passes road related issues onto Marlborough Roads as its agent 1 The RIMS Group is a working group of INGENIUM, comprising representation from Local Authority and the NZTA. 30 September 2014 Page 27 of Section 1
