Construction estimating involves a systematic process to determine the cost of a construction project. It is essential for effective project planning, budgeting, resource management, risk management, decision making, and client communication. Accurate estimations contribute to successful construction projects by minimizing financial risks, improving project outcomes, and enhancing client satisfaction.
The steps outlined below provide a general estimating framework, but the level of detail and specific considerations may vary depending on the project and the estimator’s expertise:
Project Review: Review all project documentation, including drawings, specifications, and any other relevant information. Understand the scope of work, project requirements, and objectives.
Quantity Takeoffs: Quantify and measure the various components of the project, including materials, labor, equipment, and other resources required for construction. This step involves breaking down the project into smaller elements and determining the quantities of each item needed.
Pricing: Gather pricing information for the different items identified during the quantity takeoff. This includes obtaining current prices for materials, labor rates, equipment rentals, subcontractor quotes, and other project-related costs. Consider factors like market conditions, geographical location, and project complexity when determining prices.
Labor and Productivity Analysis: Asses the labor requirements for each activity in the project. Analyze the productivity rates of the workforce based on past projects or industry standards. Estimate the number of labor hours required for each task.
Subcontractor Bids: If the project involves subcontractors, obtain bids from them for their specific scopes of work. Evaluate the bids based on price, reputation, experience, and capability.
Material and Equipment Costs: Determine the costs of materials and equipment required for the project. Consider factors such as quantity, quality, delivery, storage, and any additional costs associated with handling or using specific materials or equipment.
Indirect Costs: Account for indirect costs that are not directly associated with specific project items but are necessary for the project’s execution. These costs may include permits, insurance, project management, temporary facilities, and overhead expenses.
Markup and Profit: Add a markup or profit margin to the estimated costs. This ensures that the contractor covers their overhead expenses and generates a profit. This markup can vary depending on the contractor’s business strategy, market conditions, and risk factors associated with the project.
Contingencies: Include a contingency amount in the estimate to account for unforeseen or unknown factors that may arise during construction. This provides a buffer for potential cost overruns or changes in the project scope.
Finalize and Present Estimate: Summarize the detailed estimate into a comprehensive document. Present the estimate to the client, including a breakdown of costs, assumptions made, and any exclusions. Ensure clarity and transparency in the estimate presentation.
It’s important to note that construction estimating is a complex process, and there are various methods and techniques available. Here are a few commonly used ones:
Elemental Estimating: This method involves breaking down a construction project into distinct elements or components, such as foundations, walls, roofing, electrical systems, plumbing, etc. Each element is estimated separately based on its quantity, unit cost, and associated labor and materials.
Assembly Estimating: This involves grouping related activities or items into assemblies or systems. Instead of estimating individual components, the estimator calculates the cost of entire assemblies. For example, an assembly could be a wall system consisting of framing, installation, drywall, finishes, etc. Assembly estimating can improve efficiency by reducing the number of individuals estimates.
Unit Cost Estimating: In this method, the estimator assigns a unit cost to a specific item or activity based on historical data or industry averages. The unit cost is then multiplied by the quantity required to determine the total cost. Unit cost estimating is often used for repetitive or standardized items, such as flooring, painting, or roofing.
Cost Indexing: Cost indexing is a technique that adjusts historical costs to reflect current market conditions. It involves multiplying past costs by an appropriate cost index that accounts for inflation, changes in material prices, labor rates, and other factors affecting cost escalation. Cost indexing helps estimate the current cost of a project based on past data.
Three-Point Estimating: Three-point estimating combines the concepts of optimistic, pessimistic, and most likely scenarios to determine a range of possible costs. Instead of relying on a single value, the estimator assigns three values for each item: the best-case scenario, the worst-case scenario, and the most likely scenario. This approach accounts for uncertainties and helps assess the potential impact of risks.
