Construction is a big investment. Building construction cost estimation guide is essential in determining the type of building, whether residential or commercial. You can’t control your budget by overestimating the cost. This can cause many problems. Understanding the building cost, estimating methods, and project budgeting is crucial. In this blog, we will discuss it in great detail. 

What Is Construction Cost Estimation? 

Estimating the costs of construction is the term used to describe this process. Materials, labor, equipment, and other expenses are included in the process. An accurate appraisal assists in making informed decisions and prevents erroneous spending. 

Approximately three-quarters of construction projects are over budget due to poor cost estimation, as reported by industry sources. We need to calculate the appropriate amount before starting work.

What Makes Construction Cost Estimation Significant? 

1. Avoids Extra Costs: Missing the mark can lead to financial strain before the completion of the project. 
2. Helps in Project Planning: A breakdown of the overall construction price can aid in project planning and cost control. 
3. Reduces Wastage: Effective estimation can help avoid wasteful material procurement. 
4. Attracts Investors: A well-crafted budget builds the confidence of investors and lenders, thereby drawing them in. 
5. Ensures Timely Completion: Proper cost estimation ensures timely completion, allowing for better planning and punctuality of work. 
6. Improves Decision Making: Preferential judgment of construction expenses can assist in making informed financial choices. 

Major Factors Affecting Building Cost

Various factors influence the cost of construction. Here are some of the significant ones: 

• The cost of materials such as cement, bricks, steel, and wood is constantly changing. The cost of steel saw a 50% increase in 2021, which had an impact on several projects. 
• The remuneration of workers is subject to variation among sectors and professions. The faster the work, the higher the price of a skilled worker. 
• Heavy equipment and machinery, such as cranes and bulldozers, come with a high price tag. Their rental fees increase as they stay with us for more extended periods. 
• Depending on where the project is located, materials and labor transportation will be expensive due to its remote location. 
• A high-rise building is more expensive than a simple house due to Project Complexity. Building costs increase with complexity.
• Government regulations in certain cities are strict, necessitating additional permits and safety measures to meet the overall cost. 
• High demand for labor and materials in construction leads to an increase in overall expense. 

Different Estimating Methods in Construction

The total cost of a construction project can be estimated using various methods. The following are some of the usual ones: 

1. Preliminary Estimate

This technique is also referred to as an approximate estimate and is utilized during the early planning phase. It offers an overall idea of the cost of constructing. Despite its lack of detail, it assists in making important decisions. 

2. Detailed Estimate

The method involves the utilization of all components, such as raw materials, labor, equipment, and overhead expenses. This is the most precise way to estimate construction costs. While a detailed estimation may require some time, it can prevent costly expenses in the future. 

3. Quantity Takeoff

The quantity of materials, such as bricks or cement bags, is calculated using this technique. This helps with cost control for materials. 

4. Unit Cost Estimate

The cost per unit is determined through this approach. A house with a square footage of 1000 square feet will cost $150,000, which is more than the $150 expense of building one square foot. 

5. Parametric Estimating

This approach utilizes historical data and formulas to anticipate the total cost. It’s advantageous to observe previous endeavors. 

6. Assembly Estimating

This method breaks the project into smaller components like walls, roofing, or flooring and estimates costs for each section separately.

Strategies to Manage Construction Costs in Project Budgeting 

Once you have estimated the cost, the next step is to budget the project. A budget is a financial structure that ensures the project’s sustainability. The following are some pointers for budgeting: 

1. Construct a Cost Profile: Segment the expenses into materials, labor, equipment, and other costs. 
2. Maintain a Contingency Fund: Maintain a contingency fund as construction projects may encounter unexpected expenses. Keep an extra 10-15% for such scenarios. 
3. Compare Prices: Always compare prices from different suppliers before making a purchase. 
4. Real-Time Accuracy: Technology can be utilized to estimate construction costs and track expenses with real-time accuracy. 
5. Review the Budget: Make sure to review the budget weekly and ensure that expenses are kept under control. 
6. Bulk Purchases: Agree with suppliers to negotiate reduced prices for bulk purchases, which can help reduce costs. 
7. Reduce Waste: Planning for labor and material use can help reduce waste and save money. The key is to maximize work efficiency. 

Real-world Illustrations of Construction Cost Estimation

For instance, suppose you want to build a home that is 1500 square feet. Here’s an estimated cost breakdown: 

• Materials: $90,000. 
• Labor: $50,000. 
• Permits and Fees: $10,000. 
• Equipment: $15,000. 
• Miscellaneous: $5,000. 
• Total Cost: $170,000. 

Efficiently estimating costs can aid in cost-cutting and saving money. 

Routine Mistakes in Construction Cost Estimating

• Permit fees, insurance, and site preparation costs are often overlooked in projects. 
• Material costs are adjusted annually by utilizing outdated prices. Always ensure that you are aware of the latest prices before estimating. 
• Even the smallest expenses, such as household items like nails and safety gear, should be included in the budget. 
• Always seek advice from an expert estimator if you’re uncertain about anything. 
• Numerous projects overlook risks such as delays, adverse weather, or material shortages.
