Taming the Overhead Beast: A Guide for Cost Engineers and Project Control Teams on Managing Overhead Costs in Building Construction Projects

The construction industry, a dynamic and complex ecosystem of interconnected activities, thrives on the careful management of resources, including finances. Within this landscape, overhead costs present a constant challenge, often impacting project profitability and ultimately, the success of the project as a whole.

This comprehensive guide addresses the critical issue of managing site overhead costs in building construction projects, specifically focusing on the Egyptian construction industry.

?The insights and methodologies presented here offer valuable advice to cost engineers and project control teams, empowering them to navigate the complexities of overhead cost estimation and control, ultimately leading to more accurate project estimates, improved project delivery, and enhanced profitability.

The Overhead Challenge:

The construction industry, especially in Egypt, is experiencing a significant shift with the increasing involvement of specialty contractors.

This shift has led to a rise in general contractor/construction firm overhead costs, comparable to direct costs. While direct costs are typically tied to tangible elements like labor, materials, and equipment, overhead costs encompass a broader range of expenses related to the project's overall management, administration, and support. These costs are often less tangible, making them harder to track and control.

Site Overhead Costs: The Hidden Expenses:

Site overhead costs are a major area of concern for construction projects. These are indirect costs that are essential for the successful execution of the project but are not directly incorporated into the finished product. Examples include:

• Site Staff:?Project managers, engineers, surveyors, and other personnel directly involved in overseeing the project.
• Site Maintenance:?Cleaning, clearing debris, and maintaining the site for safety and efficiency.
• Equipment:?Mechanical plant and equipment used for construction that is not directly tied to a specific work item.
• Temporary Services:?Accommodations, utilities, and welfare provisions for workers on site.
• Transportation:?Moving workers, materials, and equipment to the site.
• Contingency:?Expenses reserved for unforeseen circumstances or changes during the project.

The Consequences of Mismanaged Overhead Costs:

Failing to accurately assess and manage site overhead costs can have significant consequences for construction companies, including:

• Underestimating Project Costs:?An inaccurate estimation of overhead costs can result in a low bid, potentially winning the project but with a reduced profit margin or, even worse, leading to financial losses during the project execution.
• Missed Opportunities:?Overlooking significant overhead cost drivers can lead to inefficient resource allocation and lost opportunities for maximizing profit margins.
• Reduced Competitiveness:?Construction companies with inadequate overhead cost management systems are at a disadvantage when competing with international firms who have more sophisticated cost control methodologies.

The Importance of a Robust Approach:

• Project Location:?Factors like the availability of skilled labor, transportation costs, and local regulations in different locations across Egypt significantly impact site overhead costs.
• Special Site Preparation Needs:?Projects requiring special site preparation, such as temporary access roads, security fencing, or additional construction equipment, often incur higher overhead costs.

Less Significant Factors:

• Nature of the Client:?Whether the client is a public entity or a private client, the impact on site overhead costs is relatively less significant compared to other factors.
• Type of Contract:?While both cost-plus and fixed-price contracts are prevalent, their influence on site overhead costs is not as significant as other factors.
• Contractor-Joint Venture:?While joint ventures are common, their impact on site overhead costs is less pronounced compared to other factors.
