What is a Change Order in Construction in the USA?

In the dynamic world of construction, the term change order plays a pivotal role. It is a formal document that modifies an existing contract between a contractor and the project owner. Understanding change orders is essential for anyone involved in construction, as they are inevitable in nearly every large-scale project. These changes are common in the construction industry and can arise due to a variety of reasons, including alterations in scope, unforeseen circumstances, or regulatory compliance issues. This article will provide a comprehensive overview of change orders in construction, highlighting their significance, types, and best practices for handling them.

What is a Change Order in Construction?

A change order in construction refers to a written order that modifies the original construction contract. It alters aspects of the contract such as scope of work, contract price, project timelines, or specifications. Change orders can be issued by either the contractor or the client, and they must be formally agreed upon by both parties before any modifications are made. These changes can impact the cost, quality, and delivery of the project, making them a critical aspect of managing a successful construction process.

Why are Change Orders Needed?

Change orders are needed for a variety of reasons, some of which are foreseen, while others are unforeseen. Common reasons for issuing change orders include:

• Design Changes: Sometimes, clients request modifications to the project’s design after the initial contract is signed.
• Unforeseen Conditions: These may include hidden site conditions such as poor soil quality, unexpected weather patterns, or the discovery of hazardous materials.
• Errors or Omissions: Mistakes in the design documents or bid specifications may require adjustments during construction.
• Regulatory Compliance: Changes in local laws, building codes, or other regulatory requirements may necessitate alterations in the construction plan.
• Additions or Deletions: The project owner might decide to add new features or remove existing elements during construction.

These modifications are inevitable in most construction projects, which is why change orders are an essential part of the contract.

Types of Change Orders

In construction, change orders can take several forms, depending on the nature of the changes being made. The most common types include:

1. Direct Change Order

A direct change order occurs when the project owner or contractor directly agrees to modify the scope of work or project cost without requiring any additional negotiation. This type of change order is typically straightforward and may involve small adjustments to the project.

For example, if a project owner wants to change the color of a building’s exterior or add a feature, a direct change order is issued.

2. Time and Material Change Order

A time and material change order is used when the scope of the work changes in a way that requires additional labor, materials, or resources. In this case, the contractor is reimbursed for the actual costs incurred due to the change, in addition to a set markup for overhead and profit.

This type of change order is commonly used when the scope is unclear or when unforeseen conditions arise that cause delays or require more materials. It allows flexibility in pricing and can be a useful tool for projects with high uncertainty.

3. Cost-Plus Change Order

A cost-plus change order occurs when the project cost increases due to additional work. The contractor is paid for the cost of the work plus a percentage markup for overhead and profit. This type of change order can be used for work that is not initially included in the project contract but is necessary for the successful completion of the project.

Cost-plus change orders are frequently used in situations where it is difficult to predict the final cost of changes due to complex design or unforeseen conditions.

4. Unit Price Change Order

A unit price change order is used when the scope of the work changes in a way that can be quantified using a unit price. For example, if a contractor needs to add additional cubic yards of concrete or a specific number of bricks to a building project, a unit price change order will be used to calculate the total cost of these additions.

This type of change order is useful when the contractor has pre-agreed-upon unit rates for common tasks, such as labor or material costs, making it easier to calculate the impact of changes on the overall budget.

The Change Order Process

The process of issuing and approving a change order typically involves several steps. It is essential that both the project owner and the contractor follow a clear procedure to ensure transparency and prevent disputes. Below is a general outline of the change order process:

Step 1: Identification of the Need for a Change

The need for a change can arise at any stage of the construction project. When either the contractor or the project owner identifies the need for a change, it is important to document the change and its potential impact on the project. This could involve new design specifications, unforeseen site conditions, or a request from the project owner.

Step 2: Proposal and Agreement

Once the change has been identified, the contractor will typically submit a change order proposal outlining the necessary adjustments. This proposal should include a detailed description of the work required, the estimated cost, and the impact on the project timeline.

Once the proposal is reviewed, the project owner will either accept or reject the change. If accepted, both parties will sign the change order, making it an official amendment to the original contract.

Step 3: Impact on Project Cost and Schedule

After the change order is accepted, the next step is to assess its impact on the project’s overall cost and schedule. Change orders that affect the project’s timeline must be addressed in terms of how they will delay the project’s completion.

Step 4: Implementation of the Change

Once the change order is signed, the contractor will proceed with the implementation of the change. This could involve sourcing additional materials, adjusting the work schedule, or modifying the project’s design. The contractor will also need to update the project’s cost tracking to reflect the adjustments made.

Step 5: Documentation and Final Accounting

The final step in the change order process involves documenting all changes and finalizing the adjustments to the project’s accounting. This ensures that the cost overruns or adjustments are properly recorded and that the contractor is reimbursed accordingly. Final documentation also helps avoid potential disputes later in the project or after its completion.

How to Avoid Change Orders in Construction

Although change orders are common in construction projects, they can lead to delays, increased costs, and conflicts if not managed properly. Here are some strategies to minimize the need for change orders:

1. Thorough Planning and Design

One of the best ways to minimize change orders is to invest time in comprehensive planning and design. By carefully evaluating the project’s requirements, potential challenges, and desired outcomes, you can reduce the likelihood of unexpected changes during construction. Proper planning helps ensure that both parties—contractor and project owner—have a clear understanding of the project’s scope and objectives from the start.

2. Accurate Estimates and Bidding

Providing accurate project estimates and clear specifications during the bidding process can help minimize change orders. When contractors have a detailed understanding of the project requirements, they are less likely to encounter unexpected changes during the construction process.

3. Addressing Issues Early

If unforeseen conditions or changes in scope are likely to arise, address them early in the process. By identifying potential issues upfront and discussing them with all stakeholders, it becomes easier to incorporate adjustments into the project before work begins.

4. Clear Communication

Good communication between the project owner, contractor, and subcontractors is essential. Ensure that all parties are aligned on project expectations, timelines, and deliverables to reduce the likelihood of disagreements or misunderstandings that may lead to change orders.

Conclusion

In conclusion, a change order is an important element of the construction process that ensures flexibility and adaptability when unforeseen issues arise or scope changes are requested. Whether due to design alterations, unforeseen conditions, or regulatory requirements, change orders provide a formal mechanism for adjusting the project contract. Understanding the types, processes, and strategies for managing change orders can help both contractors and project owners navigate these changes efficiently, keeping projects on track in terms of both cost and timeline.

By establishing clear communication, effective planning, and robust documentation processes, the risks associated with change orders can be mitigated. Proper management of change orders ensures that construction projects are completed successfully, meeting all expectations while minimizing delays and cost overruns.
