In the construction project, accurate data holds significant importance. With the expansion of the construction project, it has become difficult to maintain the timeline of the project related to resources and budget. Without a proper analysis, it is a daunting task to manage all the phases of construction. In this regard, Elemental Cost Analysis (ECA) comes in handy as it shines a light on project expenses through all the phases of the construction project.
ECA is a cost management technique that is used to break down costs and analyze the total cost of building a project by determining the costs of materials, labor, equipment, and contingencies. The blog will guide you through what elemental cost analysis is, the basic components of ECA, its benefits, process, methodologies, and applications. Let’s delve into the guidelines.
What is Elemental Cost Analysis?
Elemental Cost Analysis is a technique for breaking down construction expenses and costs into basic components, including labor, materials, contingencies, and overhead. By breaking down the cost items, one can allocate funds more easily, giving a detailed analysis and cost control in the construction project. ECA helps clients, contractors, and project managers to identify hidden surprises and cost overruns while helping them to make informed decisions to keep their project within budget.
Basic Components of ECA
ECA consists of basic components that are characterized by the fundamental aspects of a construction project.
Materials
This component contains all the physical elements that are required to complete the project. It includes concrete, bricks, lumber, cement, and steel rods.
Equipment
This component of the ECA possesses information about all the equipment, such as machinery, tools, and software, that is necessary to complete the project. It also includes the rental cost of all equipment that is used in the construction.
Labor
It covers all the expenses of the construction project that are associated with the labor force. It also includes the labor that is required during the different stages of the project, such as mechanical, electrical, and plumbing (MEP). In this step, different types of labor force, such as project managers, contractors, subcontractors, lenders, and vendors, are taken into account.
Subcontractors
It involves the cost of bids that are used in hiring specialized contractors for various subdivisions, including lumber, electrical, and mechanical contractors.
Overhead expenses
Overhead expenses are defined by the indirect costs that can influence your project’s budget. It includes permits, local codes, administrative costs, insurance fees, and contingencies.
Why Use ECA for Project Budgeting?
The accurate cost analysis in construction stems from the use of ECA for project budgeting. Here are the advantages of ECA.
Improved accuracy in Cost Estimation
ECA is important for the accuracy of cost estimations as it provides a granular view of the project’s expenses. ECA offers a detailed view of each cost element, ranging from the material selection to the labor hours that are needed for each phase of the plan. It ensures more precise budgeting and reduces the chances of cost overruns and surprises.
Budgetary Control
ECA delivers a comprehensive and detailed overview of costs, helping control overhead and overspending. Project managers can track spending on each element, so as to stay within budget.
Informed Decision-making
ECA gives all the stakeholders involved in the project actionable insights, helping them to steer the construction project efficiently. The stakeholders can assess the financial condition of the project by breaking down all the costs of basic components used in ECA. Resultantly, the stakeholders are equipped with insights and useful details can make informed decisions.
Allocation of Resources
It helps allocate resources efficiently by identifying the most crucial areas. The managers can allocate the spending and resources accurately by knowing the cost and necessity of each element. This approach ensures that some important areas of the project receive adequate funding and attention.
Streamlining the Project
ECA also plays an important role by enabling more realistic timelines and resource distribution. After understanding the cost implications of every element used in the project, one can easily streamline the project and optimize the use of elements. The planning helps in more efficient project execution and streamlining.
Risk Assessment & Management
Project managers can predict risks involved in a construction project and plan accordingly. For example, if materials prices rise unexpectedly, managers can adjust other parts of the budget to accommodate this change, minimizing the impact on the overall construction project.
The Process of ECA
The construction cost analysis consists of three steps of ECA, helping the project managers to project cost breakdown clearly and effectively.
1. Identification of Elements
The first step in ECA revolves around identifying elements used in the construction projects. These elements include iron, wood, concrete, brick, and steel. At every step, these elements are usually handled by the various contractors and project managers according to their expertise and professionalism. In this regard, BIM software helps create a virtual model to understand all essential elements for the project’s completion.
2. Assigning Costs to Each Element
The next step is breaking down all elements into different classes according to their uses and characterization. After summarizing all the elements into different categories, one must assign costs to each element. One can assign costs to different elements such as materials, labor, equipment, permit fees, and raw materials.
3. Summarizing and Analyzing the Data
After assigning costs to each element, the next step is based on the calculation of all components that belong to different categories. The accuracy in cost calculation depends on in-depth knowledge of market trends and strong knowledge about recent market rates of materials, and a labor per hour rate based on their expertise. The final step of ECA is summarizing and analyzing the cost data by using cutting-edge tools and software. One must keep these costs within one’s budget. In the case of exceeding the budget limit, you need to review your costs to make them adjustable.
