Have you ever wondered why the operating and maintenance (O&M) costs of a project are surprisingly high compared to the initial design and construction expenses? This is a significant issue often overlooked by investors and project managers, yet it heavily impacts the long-term financial effectiveness of a project.

In reality, O&M costs can greatly surpass the initial design and construction expenses, not only creating financial pressure but also affecting project profitability. How can we address this issue?

This article delves deeper into operating and maintenance costs, comparing them with design and construction expenses, analyzing influencing factors, and exploring effective strategies to minimize these costs. Let’s look into optimizing design and construction processes to achieve a sustainable and cost-effective project!💡

Understanding Operating and Maintenance Costs

Definition of Operating Costs Operating costs refer to the total funds required to maintain the daily operations of a project or facility. This includes expenses like electricity, water, labor, consumables, and other routine costs.

Importance of Long-Term Cost Management Effective long-term cost management is essential for ensuring project sustainability and efficiency, supporting profitability, resource allocation, and extending asset life.

Comparison of O&M Costs with Design and Construction Costs Operating and maintenance costs can significantly impact a project's total budget. Often, O&M costs can be 3-5 times the initial design and construction expenses and may account for up to 80% of a building's total lifetime costs.

Components of Maintenance Costs

Maintenance costs include various elements, typically classified as follows:

Cost Type	Example
Direct Costs	Materials, replacement parts
Labor Costs	Maintenance staff wages, training
Indirect Costs	Maintenance equipment, management software
Contingency Costs	Reserve funds for unexpected incidents

Understanding and effectively managing these elements can help optimize overall maintenance expenses. Next, we’ll compare operating costs with design and construction costs to get a comprehensive view of the project’s total cost.

Comparing Operating Costs with Design and Construction Costs

When assessing an overall construction project, comparing operating costs to design and construction expenses is a critical step. Let’s analyze this in more detail.

• Impact on Total Project Budget
  Operating and maintenance costs often constitute a large portion of a construction project’s total budget. This might surprise some, but in practice, we observe:

  • Operating costs can be 3-5 times the initial design and construction costs.
  • Over a 30-year building lifespan, operating costs can represent up to 80% of total expenses.

• Example from Real Projects

Phase	Cost (billion VND)	Percentage (%)
Design	10	5%
Construction	90	45%
Operation (30 years)	100	50%

• In this example, operating costs account for 50% of total expenses, five times the initial design costs.

Reasons for Higher Operating Costs

Several factors contribute to high operating costs:

1. Extended Timeframe: Operations span the project’s entire lifecycle.
2. Labor Costs: Staff is continuously required for operations and maintenance.
3. Energy Consumption: Ongoing costs for electricity, water, gas, etc.
4. Repairs and Replacements: Equipment needs regular maintenance and replacement.

Cost Ratio Analysis

When analyzing cost ratios, we typically see the following:

• Design Costs: 2-5% of the total cost
• Construction Costs: 20-30% of the total cost
• Operating and Maintenance Costs: 65-80% of the total cost

This demonstrates the importance of investing in high-quality design and construction to minimize future operating costs. Next, we’ll examine specific factors that impact operating and maintenance costs.

Factors Affecting Operating and Maintenance Costs

After understanding operating and maintenance costs and comparing them with design and construction expenses, let’s look at the primary factors influencing these costs. Identifying these factors provides a comprehensive view of the issue and helps in finding optimal solutions.
