Cost Estimating Analysis: PROJ6002 Bungalow Project Worksheet

This assignment presents a comprehensive cost estimating worksheet for the Bungalow Project, incorporating various estimation techniques. The worksheet includes parametric estimates, analogous estimates, and three-point estimates to determine project costs. The document also references a quality management plan and a cost management plan, outlining the design and construction philosophy of the bungalow. The project involves strip footings, double brick veneer walls, timber-framed floors, and tiled roofs. The construction is to be carried out by direct labor, and financed by a bank loan, with detailed payment schedules for labor, suppliers, and plant hire. The assignment provides a detailed breakdown of labor rates, work week hours, and the cost management plan, and is designed to present all cost and duration scenarios.
