Heavy construction and civil engineering are the foundations of the construction industry. They encompass the design, building, and maintenance of infrastructure that forms the backbone of our society. This includes roads, bridges, tunnels, buildings, airports, dams, water supply systems, and more. With the growing complexity of projects and the increasing competition in the market, accurate cost estimation and efficient job bidding have become essential for the success of any heavy civil construction project.
Understanding Heavy Construction Civil Engineering
Heavy construction / civil engineering involves the creation of infrastructure that benefits our communities and enhances our quality of life. It includes projects such as highways, airports, railways, bridges, dams, and buildings. These projects are usually large-scale and require significant investment, specialized equipment, and a skilled workforce.
The Role of Cost Estimation in Heavy Civil Construction
Cost estimation in heavy civil construction forms the backbone of the entire project lifecycle. It involves the calculation of all necessary costs for a project, including direct costs like materials and labor, and indirect costs like equipment depreciation and overhead expenses. Accurate cost estimation is crucial because it helps project owners determine whether a project is feasible within the given budget, and helps contractors develop competitive and profitable bids.
The Importance of Job Bidding in Heavy Civil Construction
Job bidding is an integral part of the heavy construction civil engineering process. It involves contractors submitting proposals to undertake a project based on the estimated costs. The job bidding process aims to identify the most suitable contractor for a project, based on factors such as cost, experience, and project management capabilities.
The Critical Steps in Heavy Construction Civil Engineering Estimation
Estimating the cost of a heavy civil construction project involves several steps, each of which contributes to the overall accuracy and effectiveness of the estimate. Let’s delve into these steps:
1. Reviewing the Bid Package
The first step involves a comprehensive review of the bid package, which contains all the necessary documents for bidding. The bid package includes owner-contractor agreements, bond forms, general conditions, supplementary general conditions, and construction specifications. During this review, estimators ensure they are familiar with every aspect of the project, which forms the basis for an accurate estimate.
2. Conducting a Site Visit
A site visit provides the estimator with firsthand information about the site conditions, which can greatly influence project costs. Conditions such as poor drainage, difficult subsurface soil conditions, adjacent buildings, poor accessibility, or poorly located utilities, could add complexity and cost to a project.
3. Performing a Material Takeoff
To perform a material takeoff, you need to examine the construction documents and count every required item for the project. The list of material requirements is usually organized according to their measurements, such as quantity, area, volume, and length.
4. Soliciting Pricing from Suppliers and Vendors
Once the material takeoff is complete, estimators work with suppliers and vendors to get pricing information for materials and equipment. This process includes considering factors such as material waste, bulk pricing, and the lifespan of quotes.
5. Evaluating Labor Requirements
Estimators also need to determine the labor necessary for a project. This involves identifying the roles required for the project, estimating how many hours of labor will be needed, and assessing how productive the crew will be based on past projects and current project information.
6. Determining Insurance and Bonding Costs
Insurance and bonding costs are also crucial factors in the cost estimation process. These costs help mitigate risk for both owners and contractors and need to be included in project estimates.
7. Calculating Overhead and Indirect Costs
To calculate the total project cost, estimators need to consider the direct costs of the project as well as the indirect costs related to construction field expenses and general business overhead. Indirect costs may include permit fees, site cleanup, temporary trailers or offices, professional services, equipment expenses, and software costs.
8. Accounting for Profit and Contingency
The estimator will adjust the total cost of a construction project by adding profit margin and contingency after factoring in all expenses. The profit margin is the contractor’s fee, while contingency is a reserved amount for possible overruns and waste.
The Role of Heavy Civil Software in Cost Estimation and Job Bidding
In the heavy construction civil engineering industry, leveraging advanced heavy civil estimating software is becoming increasingly important. This software helps streamline the cost estimation and job bidding process, reducing human errors and increasing productivity.
Some of the top heavy construction software platforms include: Vizzn, Heavy Bid, Bid2Win, and others.
1. Avoiding Spreadsheet Errors
One of the primary benefits of using heavy civil software is the avoidance of costly spreadsheet errors. Spreadsheets are prone to errors due to manual data entry, complex formulas, and lack of real-time updates. In contrast, heavy civil software automates these processes, reducing the risk of errors and ensuring accuracy.
2. Establishing Cost Structures and Templates
Heavy civil software allows for the creation of cost structures and templates, which can significantly enhance the speed and accuracy of the cost estimation process. By having a centralized resource database, everyone involved in preparing bids has access to accurate and up-to-date costing information.
3. Speeding Up the Bidding Process
The use of heavy civil software can significantly speed up the bidding process. The more bids a contractor can complete accurately and confidently, the more chances it has to win work.
4. Enhancing Collaboration
Heavy civil software also facilitates effective collaboration among team members. This is particularly important for larger companies bidding on large and complex projects, where several people are required to provide input during the bid preparation process.
5. Connecting with the Field and Accounting System
Integration with the field tracking systems and accounting systems is crucial for efficient cost estimation and job bidding. This integration ensures real-time updates, enhances communication, reduces re-work, and promotes accuracy.
6. Optimize Electronic DOT Bidding Systems
For contractors who frequently prepare bids for Departments of Transportation (DOTs), heavy civil software provides significant time-saving advantages. This software allows for the import of electronic bid forms, automatic conversion of estimates to match the DOT format, and easy upload of the bid for submission.
Conclusion
In the realm of heavy construction civil engineering, cost estimation and job bidding are fundamental to project success. The use of heavy civil software has revolutionized these processes, enhancing accuracy, efficiency, and collaboration. By adopting these advanced tools and following the outlined steps, contractors can significantly increase their chances of winning bids and delivering successful projects.
