Development of a Maintenance Management Model for Integrating Other Stakeholders' Utilities Network into Road Maintenance Project to Enhance Road Maintenance Performance: A Case Study of Kinondoni District, Tanzania

Abstract

This study developed an effective maintenance management model to improve coordination between road maintenance projects and utility networks (water, electricity, and telecommunications) in Kinondoni District, Tanzania. The research addressed the critical problem of unplanned utility disruptions during road works, which cause project delays, increased costs, and premature road damage. With only 36% of Kinondoni's roads in good condition, improving coordination between TARURA (road authority) and utility providers (DAWASA, TANESCO, TTCL) has become essential for sustainable urban development. The research employed a mixed-methods approach combining quantitative surveys with 40 professionals, qualitative interviews with engineers and technicians, and detailed case studies of five problematic road sections. Data collection included structured questionnaires administered to technical staff from road and utility agencies, in-depth interviews with project managers and field engineers, and a comprehensive analysis of maintenance records from 2019-2023. The study utilised Geographic Information Systems (GIS) mapping to visualise utility network overlaps and conflict zones along major transportation corridors. Key findings identified poor information sharing (reported by 78% of respondents) and conflicting schedules (65%) as major obstacles to effective coordination. Additional challenges included inadequate advance notification systems (72% of cases), lack of standardised excavation procedures (68%), and insufficient cost-sharing mechanisms (61%). The developed model, which introduces joint planning sessions, a shared digital platform, and standardised coordination protocols, demonstrated an 82% improvement in coordination efficiency during pilot tests conducted on three road segments. Notably, projects using the model reduced delays by an average of 37% compared to conventional approaches, while maintenance costs decreased by 24% due to reduced rework requirements. The study recommends establishing a dedicated Utility Coordination Unit within Kinondoni Municipal Council, implementing comprehensive GIS-based utility mapping systems, developing standardised utility relocation procedures, and mandating utility corridor designation in all new road designs. Professional development programs should enhance stakeholder capacity in integrated infrastructure planning, while the developed model should be incorporated into municipal planning processes to ensure minimum integration standards for project approval. The study provides a practical framework applicable not only to Kinondoni but to other Tanzanian urban areas facing similar infrastructure management challenges.
