Estimator's Man-Hour Manual An estimator's man-hour manual is a reference book used to estimate the time required to complete a specific task or project. It provides a detailed breakdown of the tasks involved, the estimated time required for each task, and the total man-hours needed to complete the project. The manual is used by estimators, project managers, and contractors to prepare bids, proposals, and project schedules. Technical Calculations Technical calculations are an essential part of estimating and project management. They involve the use of mathematical formulas and equations to determine the quantities of materials, labor, and equipment required for a project. The calculations are based on the project's specifications, drawings, and scope of work. Some common technical calculations used in estimating and project management include:
Quantity takeoff : This involves calculating the quantities of materials required for a project, such as concrete, steel, and lumber. Labor productivity : This involves calculating the amount of time required for a worker to complete a specific task, such as installing a certain number of electrical fixtures. Equipment productivity : This involves calculating the amount of time required for a piece of equipment to complete a specific task, such as excavating a certain volume of soil. Material pricing : This involves calculating the cost of materials required for a project, including the cost of purchasing, transporting, and storing the materials. Labor costing : This involves calculating the cost of labor required for a project, including wages, benefits, and overhead.
