Types of Contracts in Construction You Need to Understand

Understanding construction contracts is crucial for anyone involved in the construction industry. Whether you are a contractor, subcontractor, or project manager, having a thorough understanding of different types of construction contracts can help you mitigate risk and ensure successful project completion.

The role of contracts in construction projects cannot be overstated. Contracts serve as legally binding agreements between parties involved in the construction process, outlining the scope of work, payment terms, and other crucial details. Clear and well-written contracts can save you from potential disputes and costly legal battles.

‍

What Is a Construction Contract?

Construction contracts are legally binding agreements that outline the specific work to be carried out by a general contractor and the corresponding payment obligations of the project owner. These contracts play a crucial role in facilitating effective construction management, ensuring that both parties are aware of their responsibilities and expectations.

Despite variations in complexity and scale, the contract process differs from a one-on-one approach. It involves a careful negotiation and drafting process, where the terms and conditions of the agreement are discussed and agreed upon. This includes defining the scope of work, project timelines, quality standards, and any special provisions that may be required.

Over time, various types of construction contracts have emerged to cater to different project needs. These include lump sum contracts, where a fixed price contract is agreed upon for the entire project, time and materials (TM) contracts, where the contractor is paid based on the time and materials used, and unit pricing contracts, where the price is determined by a predefined unit rate.

To effectively manage these contracts, construction professionals rely on robust contract management software like Project Manager. This software streamlines the contract administration process, allowing for efficient document management, tracking of deliverables, and monitoring of project progress. By centralizing contract information and automating key tasks, Project Manager helps ensure that construction projects stay on track and are completed successfully.

Types of Contracts in Construction

There are several types of construction contracts that you should familiarize yourself with before starting any construction project. Each type has its own unique characteristics, benefits, and drawbacks. Let's take a closer look at some of the most common construction contracts:

Lump Sum Contracts

This is perhaps the most commonly used type of construction contract. As the name suggests, a lump sum contract involves a fixed price for the entire project, which is agreed upon by both parties before any work begins. Lump sum contracts is suitable for projects with well-defined scopes of work, making it easier to estimate the final cost.

Pros:

• Provides a clear understanding of project costs
• Limits the client's financial risk

Cons:

• Any changes to the scope of work can result in extra charges

When to Use:

Lump sum contracts are ideal for small to medium-sized projects with specific and well-defined scopes of work. They are also commonly used for residential construction projects.

Cost Plus Contracts

In cost plus contracts, the contractor is paid for the actual costs incurred during the project, plus a predetermined fee or percentage of the total cost as profit. This type of contract is usually used when the scope of work is not easily defined, and there is a high risk of changes or delays.

Pros:

• Allows for flexibility in project scope and changes
• Ensures the contractor is fairly compensated for their work

Cons:

• Can lead to higher costs if not managed properly

When to Use:

Cost plus contracts are suitable for projects with a high degree of uncertainty or complexity, such as large commercial construction projects.

Time and Materials Contracts

Similar to cost plus contracts, time and materials contracts also involve paying for actual costs plus a fixed fee. However, with time and materials contracts, the project's scope is not clearly defined, and the client pays for all materials, labor, and equipment used.

Pros:

• Offers flexibility in project scope
• Allows for adjustments based on project progress

Cons:

• Can result in higher costs if not managed properly

When to Use:

Time and materials contracts are commonly used for projects with a high level of uncertainty or those that require frequent changes in the scope of work.

Unit Price Contract

In a unit price contract, payment is based on predetermined unit rates for specific items or tasks. This type of contract is useful when there is a standard set of tasks or items that can be easily quantified.

Pros:

• Allows for accurate cost estimation
• Provides flexibility in project scope

Cons:

• This can result in higher costs if there are changes to the unit rates

When to Use:

Unit price contract is suitable for projects with a repetitive nature, such as road construction or landscaping projects.

Guaranteed Maximum Price Contract (GMP)

Under a Guaranteed Maximum Price Contracts, the contractor guarantees that the project will not exceed a certain maximum price. Any savings made during the project are typically split between the owner and contractor. This type of contract provides cost certainty for clients while still offering flexibility for changes in scope.

Pros:

• Provides cost certainty for clients
• Encourages collaboration between owner and contractor to efficiently manage costs

Cons:

• Can be more expensive compared to other types of construction contracts

When to Use:

GMP contracts are commonly used for large-scale commercial or public projects, where the scope of work may change or evolve during the construction process.

Incentive Construction Contracts

Incentive contracts offer an additional incentive for contractors to meet certain project objectives, such as completing the project ahead of schedule or within budget. The contractor is typically rewarded with a bonus or additional compensation if these goals are met.

Pros:

• Encourages contractors to perform at their best
• Provides extra motivation to complete the project on time and within budget

Cons:

• Can be more expensive for the client due to added incentives

When to Use:

Incentive contracts are beneficial for projects with strict deadlines or budget constraints, where timely completion is crucial.

Integrated Project Delivery Contract

In this type of construction contract, all parties involved in a construction project (owner, contractor, and architect/engineer) work collaboratively from the start to achieve common goals. This approach promotes early involvement of all stakeholders and encourages constant communication and collaboration throughout the project.

Pros:

• Encourages collaboration between all parties involved
• Emphasizes on delivering exceptional quality within budget and on time

Cons:

• Requires a high level of trust and communication between all parties

When to Use:

Integrated project delivery contracts are best suited for large, complex projects where collaboration among all stakeholders is crucial for success.

Design-Build Contract

In a design-build contract, the contractor is responsible for both the design and construction of a project. This approach streamlines the process by eliminating the need for separate contracts with designers and builders.

Pros:

Simplifies project management as there is only one point of contact for clients

• Can lead to faster project completion due to overlapping design and construction phases

Cons:

• Limited control for the client over the design process

When to Use:

Design-build contracts are ideal for projects with tight deadlines and where cost savings are a priority.
