Client-Centric Schedule Controls on Optimal Development of Water Resource Projects

Abstract

Construction delays remain one of the most critical challenges in water projects delivery, often resulting in cost overruns, schedule slippage, and weakened stakeholder confidence. Traditional time management methods are largely reactive, relying on periodic reporting and fragmented communication across project teams. Different project participants often have different objectives and expectations, and implement different controls aimed at advancing their own interest. This research explores project schedule controls exercised by clients during project design to execution for improved project time performance. To achieve the objective, 185 questionnaire sets successfully formed the sample based on 13 water projects. Data were analyzed inferentially and multiple regression for predicting the relationship. From the findings, project owners (clients) have less power in drafting and planning the scope of the work and time scheduling. Findings showed that regular progress monitoring, deadline management, team communication, and use of shared calendars and digital tools were the effective client time management practices with a combined correlation coefficient (r = 0.600, p<.001). Moreover, the findings showed that most clients experienced unrealistic timeframes, varying objectives among project stakeholders and bureaucracy as an external factor. The experienced challenges affect clients in managing project schedules negatively (r=-0.0002, p=098). These findings imply that client-schedule based controls can be an effective supplement to project delays in public construction projects in Tanzania, particularly for projects requiring project client personalized feedback. The study recommends adoption of digital and Real-Time schedule monitoring tools like Dashboards, and Real-time reporting tools to monitor project progress against approved schedules. Also, establishing early-warning and corrective-action systems for deviation control.
