Study Notes

Objectives of Estimating

Estimating helps in predicting financial requirements of a project, ensuring it remains within the budget and avoiding cost overruns and financial losses.
Estimating identifies resources needed for a project, including materials, labor, and machinery, ensuring all necessary resources are procured and available when required.
Accurate estimates enable effective scheduling, ensuring projects are completed within stipulated timelines.
Estimating allows for evaluating potential profitability of a project by comparing estimated costs with expected revenue.
Accurate estimates provide essential data for making informed decisions regarding project feasibility, scope, design, and resource allocation.
Detailed and accurate cost estimates are crucial for preparing competitive bids for contracts.

Functions of Estimating

Estimating develops detailed budgets outlining expected costs associated with a project.
Estimating involves monitoring and controlling costs throughout the project lifecycle to prevent budget overruns.
Estimating ensures all necessary resources are identified and procured in a timely manner.
Estimating creates timelines that align with resource availability and project deadlines.
Estimating identifies potential cost risks and develops strategies to mitigate them.
Estimating compares actual costs against estimates to assess accuracy and improve future estimates.

Principles of Estimating

Estimates must be as precise as possible, based on reliable data and sound judgment.
The estimating process should follow standardized procedures to ensure uniformity across different projects.
The methodology and assumptions used in estimating should be clearly documented and communicated.
Estimating methods should be flexible enough to accommodate changes in project scope, design, or market conditions.
Comprehensive records of estimates, including all assumptions and calculations, should be maintained for future reference and analysis.

Principle Factors of Estimating

Project complexity can affect the accuracy and reliability of estimates.
Clear and detailed project specifications lead to more precise estimates.
Fluctuations in material prices can impact cost estimates significantly.
Variations in labor costs, including wages, benefits, and productivity, influence estimates.
The availability and efficiency of machinery and technology can affect time and cost estimates.
Market conditions, such as supply and demand, can impact material and labor costs.
Historical data can provide valuable insights for future estimates.

Estimating Procedure

The estimating procedure involves project analysis, quantity takeoff, costing, time estimation, overhead and profit, review and validation, and documentation and reporting.
Project analysis reviews project specifications, drawings, and requirements to understand the scope and objectives.
Quantity takeoff measures and lists all materials, components, and labor required for the project.
Costing assigns costs to each item on the quantity takeoff list based on current prices and rates.
Time estimation calculates the time required to complete each task and stage of the project.
Overhead and profit add indirect costs and desired profit margins to the estimate.
Review and validation check the estimate for accuracy, completeness, and reasonableness.
Documentation and reporting prepare detailed estimate reports for review and approval by stakeholders.

Estimation of Weights & Materials

Weight estimation is essential in engineering and manufacturing, particularly for structural components, machinery, and transportation projects.
Accurate weight estimation helps in structural design, transportation planning, and cost calculation.
The process involves material selection, volume calculation, density application, and documentation.

Estimation of Machining Time

Estimating machining time involves calculating the time required to perform various machining operations.
Accurate time estimation is vital for production planning, cost estimation, and resource allocation.
The process includes operation analysis, process planning, cutting parameters, and time calculation.

Estimation of Fabrication Cost

Fabrication cost estimation involves determining the total cost to produce a component or assembly, including materials, labor, overhead, and profit margins.
Key steps include material costs, labor costs, overhead costs, and profit margin calculation.

Estimation of Forging Cost

Forging cost estimation involves calculating the expenses associated with the forging process, including material, labor, and overhead.
Key steps include material costs, energy costs, labor costs, tooling costs, and overhead costs calculation.

Estimation of Foundry Cost

Foundry cost estimation involves calculating the expenses related to casting processes, including material, labor, and overhead.
Key components include material costs, mold costs, energy costs, labor costs, and overhead costs.
