ABSTRACT: Progress measurement is cardinal for effective project delivery. It assesses the physical amount of completed work within budgeted cost and manpower performance at a specified stage of the project. Effective progress measurement facilitates progress monitoring, an inevitability for identifying early warningsigns and confirmation of structured work proceeding. Different progress measuring methods are available and used for construction projects. They range from the traditional to the contemporary ones like three-dimensional and four-dimensional models. This paper examines current progress measurement methods used in the Ghanaian construction industry. Eight commonly employed methods were identified from the literatureandrated by sixty-two construction professionals, practicing with tier one construction firms and construction consultancy services. Relative Important Index ranking and Mann-WhitneyUtest statistics were used to rank and check the consistency of survey responses. Cost Ratio rankedthehighest, followed by Supervisor’s Opinion and UnitsCompleted. The fourth-ranked method was Time Ratio, then Incremental Milestone before Start-Finish.Weighted/Equivalent Unitswas atthe penultimate with Earned Value Analysis rankedthelowest. The study will not only underscore the relevance of the current project progress measurement practices and provoke prolific debates on their merits, but will also serve as a precursor for critical evaluation of the methods with the view to identifyingbarriers militating against realistic progress assessment of construction works.
