Design-and-build projects demand robust project controls due to their complexity and overlapping responsibilities. This study investigates the functional strands, which are monitoring, evaluation, and corrective action, that underpin effective project control mechanisms from the perspective of construction companies. A purposive sample of ten experienced construction professionals, including managers, engineers, and consultants from firms with varied turnover levels, participated in a structured questionnaire. The instrument captured organizational arrangements, tools, reporting practices, and corrective action processes. Data were analyzed using descriptive statistics and thematic grouping to identify prevalent practices, efficiency levels, and challenges. Findings reveal that project monitoring is predominantly team-based (80%) and initiated as early as the design stage. Tools such as Primavera and MS Project are widely used, supplemented by progress and materials reports. Evaluation is conducted regularly, often weekly, with 80% of organizations integrating it into control team structures. Corrective action is largely management-led, with project managers responsible in 70% of cases, and is implemented collaboratively across departments. Efficiency analysis highlights significant time demands for data collection (30-50% of effort), excessive documentation burdens (80% reporting overproduction), and reliance on personnel with high technical expertise. The study confirms that monitoring, evaluation, and corrective action are interdependent strands essential to functional project controls. Challenges include documentation overload, variable reporting cadences, and limited use of specialized decision-support tools. A strategic framework emphasizing streamlined data collection, balanced reporting, and managerial responsiveness is proposed to enhance project control effectiveness in design-and-build projects.
