Abstract
The initial design phase fundamentally dictates the time, costs, and overall scale of construction efficiency in residential projects. Numerous construction issues like delays, rework and cost overruns are identified as being directly related to decisions at the initial phase of the project. This research investigates the impact of design-stage decision-making on project efficiency in residential developments (i.e. to understand powerful factors that shape outcomes).
It is research carried out with a systematic review of previous studies and a qualitative evaluation of the best practices in residential construction. The analysis considers factors such as coordination between stakeholders, design information clarity, timing of decisions and involving various disciplines. The research reveals that coordination gaps, incomplete drawings and design changes are some of the highest contributors to project inefficiencies at execution.
The results show that decision taken at early stages have a significantly greater impact on project outcomes compared to those made during later phases. Projects with improved governance include better organization, evidence of coordinated design documentation and faster decision making is shown by tighter time and cost control. Conversely, poorly structured decisions generally result in recurring failures and interruptions during the construction phase.
The study emphasizes the need to take a more structured and agreed-upon view of decision-making at design time. Early-stage process strengthens from uncertainty, workflow and predictability as per project. In sum, this research shows that to attain the efficiency of residential projects and manage their process well those decisions which are made at the design stage should be useful for delivery.
