Importance of Post-DLP Maintenance in Rural Infrastructure Development

Slide Note

The presentation by M.K. Gupta sheds light on the crucial aspect of post-Defects Liability Period (DLP) maintenance in rural infrastructure development. It emphasizes the need for timely maintenance to save assets worth millions, prevent accidents, and ensure the longevity of roads. The detailed insights cover the significance of routine maintenance, upgradation of roads, careful release of deposit amounts, and the necessity of a dedicated agency for maintenance. The module proposed for post-DLP maintenance aims to address the recurrent challenge of agency availability by providing a sustainable solution over 5-7 years. Additionally, it discusses the contractual design by NRIDA for effective post-DLP maintenance. Overall, the presentation highlights the key considerations and strategies essential for maintaining rural infrastructure effectively.

POST DLP MAINTENANCE National Rural Infrastructure Development Agency Presentation by M.K. Gupta Ret. EinC M.P.R.R.D.A

WHY MAINTENANCE One Stitch at time Saves Nine . It saves Assets of thousand of Cr. in MP 108351 Km @ 70 Lac per/km it comes about 72500 Cr. Expenditure of maintenance is 975 Cr. Which is 1.34% of assets value. You can ask maintenance fund accordingly. It prevent the Accidents Maintenance of Road is different from Building Maintenance To keep the roads in good condition Routine Maintenance, Renewal, Emergency works required to be done as and when required 1.

WHY MAINTENANCE Some Roads may require upgradation due to mining traffic and any other traffic of transportation like wheat, cement etc. Such roads should be taken for up-gradation on priority, from State Funds. MP has done upgradation of 783 roads of 5068 Km with 2227 Cr of Rs. Post DLP maintenance should start immediate after expiry of DLP. It required advance planning for estimation, tendering and agency in place for post DLP maintenance.

Point for consideration before release of roads for Post DLP maintenance Roads should be in good condition and their should not be any IR (Initial Rehabilitation) in original construction. All boards and road furniture are intact and properly painted. One should be very careful while releasing the deposit amount of DLP. MP has special provision, before releasing deposit amount of DLP. Joint inspection is conducted by two GMs on every road to verify good maintenance condition.

Some Glimpses Point of MP Total road length with MPRRDA - 108351 Km. PMGSY roads - 89351 Km. States funds roads 19000 Km. Roads in different position:- Within 5 year DLP 27051 Km Post 5 year 31666 Km Post 10 year 31184 Km Post 15 year 5467 Km Total 95368 Km

Necessity of post DLP maintenance module Main problem of maintenance is absence of agency for maintenance. Previously zonal contract or agency for 1 or 2 years is available for required maintenance. It takes time to fix the agency again and again for maintenance. This module will give you agency for maintenance for 5 to 7 year. This module will give you agency for every required maintenance in those 5 to 7 years.

Post (DLP) maintenance contract design by NRIDA Post DLP maintenance is done through separate contract for 5-7 years contract period The contract involves both work and service IR, Renewal and Emergency are works as given in BOQ Routine Maintenance is a service This is similar to contact for execution of PMGSY construction works The bidding document therefore is kept same as for PMGSY works with slight modifications 16
