Assessing the impact of scope adjustment on project cost as a measure of project success : A case study on the construction supervision of Kwik Residential Apartments in Mutungo, Kigo

Abstract

In the context of construction projects, a variation usually refers to any change or modification made to the original scope, design, or specifications of the project. Variations can arise due to various reasons such as design changes, unforeseen site conditions, client requests, changes in regulations, or any other factors that necessitate alterations to the original plans. Variations often have cost implications as they translate into increased project scope, modified design or specifications, increased quantities of materials and labour requirements. The Researcher therefore sought to assess the cost impact of scope changes as a crucial part of the project cost management process. It's important to manage variations effectively to ensure that they are properly documented, authorized, and communicated to all relevant stakeholders. This helps maintain clarity, control costs, and ensure that the project continues to meet the desired objectives despite any changes that may arise during its execution. This report therefore comprises of the causes of scope adjustments as well as their effect on cost as an indicator of project success. From previous studies, it is also highlighted that changes are almost inevitable when managing projects in practice and as such; there are project management principles and practices that have been adopted to minimise the disruption that results from scope adjustment. The Researcher therefore sought to assess how effective these change management practices have been at reducing the disruption caused by changes to successful project completion. The Researcher therefore took to active participation as an Assistant Quantity Surveyor on the Consultant's team during the construction of Kwik Apartments at Kigo to build up a detailed study and review of the issues pertaining to scope adjustment and how effectively they were handled on that Project culminating into conclusions and recommendations. The study was concluded by emphasizing the need for good rapport amongst stakeholders as handling of changes is best managed by negotiation amongst the parties beyond having a trail and justification for reasons of scope adjustment.
