How to Conduct Construction Cost Analysis

 

 

Steps to Perform a Construction Cost Analysis

Collect All Project Information

Start by gathering all the documents and details related to the project. This includes construction plans, contracts, invoices, and any other paperwork. Understanding the project’s scope and schedule helps you get a clear picture of all the costs involved.

Organise Costs into Categories

Break down all the costs into categories like labour, materials, equipment, subcontractors, permits, other overhead costs, and any unexpected expenses. Organising costs this way makes handling and analysing where the money is going easier.

Set Up a Cost Baseline

Create an initial budget or estimate at the project’s start. This baseline will help you track how well you stick to the budget as the project progresses.

Keep Track of Spending

Record all expenses regularly as the project progresses. This includes everything from the number of labour hours your workers are logging to the amount of material used. Ensure this information is accurate and updated often, especially if your project falls behind schedule.

Compare Budgeted Costs to Actual Expenses

Look at the differences between what you planned and what you spent. Understanding why these differences exist, whether due to unexpected changes or market price increases, can help you manage costs better.

Forecast Future Costs

Use past cost data and current trends to predict future expenses. Consider economic changes, material costs, or potential delays that might affect the total project cost. Accurate forecasting helps you prepare and make smart decisions.

Evaluate Cost Efficiency

Measure how effectively the project uses its budget using specific metrics like the cost performance index (CPI) and earned value. These figures show whether you’re over or under budget and by how much.

Look for Ways to Save

Always look for opportunities to cut costs. This might mean negotiating deals with suppliers, finding more efficient work methods, or eliminating unnecessary expenses.

Report Your Findings

Share your analysis with all stakeholders clearly and straightforwardly. Use reports or presentations to highlight issues, opportunities for savings, or suggestions for future projects.

Adjust and Monitor Continuously

Cost analysis isn’t a one-time task. Monitor expenses throughout the project, update your estimated cost forecasts, and tweak your strategies to stay on budget.

• Facilitates Comparisons: Makes it easier to compare costs across different projects or within different phases of the same project, providing valuable insights and benchmarks.

Disadvantages of Elemental Cost Analysis:

• Time-consuming: This method can be more time-intensive than other estimation techniques due to the detailed nature of breaking down each component.
• Complexity: Requires a high level of detail and accuracy in the initial stages of project planning, which can be complex and challenging to manage.
• Dependent on Design Completeness: Accurate cost estimation using this method relies heavily on the completeness and accuracy of the project’s design details. Incomplete designs can lead to inaccurate estimations.
• Potential for Overlooked Costs: Focusing on individual elements can lead to overlooking integrated costs or synergies between elements, which might affect the overall project budget.

 

 

Comparative Analysis

Comparative Analysis in construction cost estimating is a method where the costs of a new project are estimated based on the costs of similar, previously completed projects. This method relies on using historical data and adjusting for differences in size, materials, location, and other relevant factors to predict the actual costs of a new project.

Advantages of Comparative Analysis:

• Speed and Efficiency: This method can be faster than other techniques because it uses existing data, avoiding the need to start from scratch.
• Ease of Use: It’s relatively straightforward, especially when similar project data is readily available, making it accessible for quick, initial estimates.
• Good for Preliminary Estimates: This provides a useful ballpark figure early in the project planning process, which can help set expectations and secure initial budgets or funding.

Disadvantages of Comparative Analysis:

• Dependence on Historical Data: This method’s accuracy heavily depends on the availability and relevance of historical data from similar projects. Inaccurate or outdated data can lead to incorrect estimates.
• May Overlook Unique Aspects: Each construction project has unique aspects, and this method might not account for specific elements or challenges of the new project, potentially leading to oversights.
• Less Detail: This method provides less detailed breakdowns of costs compared to methods like Elemental Cost Analysis, which can make it difficult to perform precise budget allocations and cost controls.

 

Parametric Estimating

Parametric Estimation is a method used in construction cost estimation that involves statistical relationships between historical data and other variables (or parameters) such as square footage, capacity, or other quantifiable project characteristics. This technique applies these relationships to estimate the costs of a new project based on the defined parameters.

Advantages of Parametric Estimating:

• Efficient for Early Estimates: It’s particularly effective in the early stages of a project when detailed information may not yet be available.
• High-Level Accuracy: If accurate and relevant parameters are used, parametric estimating can quickly provide a high level of accuracy.
• Scalable and Flexible: This method can be applied to various sizes and types of projects and adjusted as more data becomes available.

Disadvantages of Parametric Estimating:

• Relies on Quality Data: The accuracy of estimates depends heavily on the quality and relevance of the historical data used to define parameters.
• Limited by Available Data: If specific data or parameters for a project type are not available, the reliability of the estimates can be compromised.
• Potential for Oversimplification: Because it uses generalised parameters, this method might oversimplify the cost of more complex project elements, leading to potential inaccuracies.
