If you are here, you probably know that different construction projects require different approaches and methods to be successful. In the world of construction, there is no one-size-fits-all solution. Each project has its own unique challenges and requirements, which is why choosing the right project delivery method is crucial for its success.

In this blog, we will delve deep into the nuances of the different construction project delivery methods, providing insights gleaned from years of experience and industry best practices. Whether you’re a seasoned professional or new to the field, this guide is designed to equip you with the knowledge to navigate the intricate landscape of project delivery methods.

What is a project delivery method?

A project delivery method is a process used to organize and execute construction projects. It outlines the roles, responsibilities, and relationships between different parties involved in the project, such as the owner, architect, contractor, subcontractors, and stakeholders.

Choosing the right project delivery method depends on various factors such as budget, timeline, complexity of the project, and risk allocation. Each method offers its own set of advantages and disadvantages that need to be carefully considered before making a decision.

The 6 Project Delivery Methods

In the construction industry, there are six commonly used project delivery methods. We’ve listed them out here but will delve into the pros and cons of each later on:

  • Design-Bid-Design: Also known as the traditional method, Design-Bid-Design involves three distinct phases: the project is first designed by an architect, then put out for bid to contractors, and finally, the construction is carried out by the winning contractor. This method allows for a clear separation of design and construction responsibilities.
  • Design-Build: Design-Build simplifies the construction process by combining design and construction services under one contract, typically leading to faster project completion and streamlined communication, as a single entity is responsible for both designing and building the project.
  • Construction Manager at Risk (CMAR): In the CMAR method, a construction manager is engaged by the owner during the design phase and is involved in the project until completion, working closely with the design team. The construction manager commits to completing the project within a Guaranteed Maximum Price (GMP), assuming the risk of cost overruns.
  • Construction Management Multi-Prime (CMMP): This approach involves hiring multiple prime contractors, each responsible for different segments of the construction work. A construction manager oversees the project, coordinating the efforts of all prime contractors, which can lead to greater control over each phase of the construction.
  • Public-Private Partnership (P3): Public-Private Partnerships are collaborative contracts between government entities and private companies, often used for large-scale public infrastructure projects. These partnerships can leverage private sector efficiencies and are characterized by shared risks and rewards.
  • Integrated Project Delivery (IPD): IPD is a collaborative alliance of people, systems, business structures, and practices. It integrates the roles of all participants through all phases of design and construction, fostering a unified workflow that emphasizes collective problem-solving and maximizes efficiency.

Now that you know the basics of each type of method, we are going to go into each in more detail and explain how they can benefit your business. It’s important to understand the differences between these methods so that you can choose the best one for your specific needs.

1. Design-Bid-Design

DBD is the traditional method of project delivery that has been used for centuries. In this method, an owner hires a design team to create plans and specifications for the project. Once these plans are completed, they are then put out to bid for contractors to compete on who can build it at the lowest cost.

Advantages

One of the main benefits of DBD, a method often encountered in construction project management, is that it allows for competitive bidding which can potentially drive down costs.  Additionally, the owner has more control over the design process and can make changes as needed before construction begins. This method also allows for a clear separation of responsibilities between the design team and contractors.

Disadvantages

However, this method also has its downsides as it often leads to adversarial relationships between the owner, architect/designer, and contractor. It also leaves little room for collaboration and input from all parties involved in the project. This can result in a lack of innovation and potential delays due to conflicts and change orders.

DBD works best for projects with clear and well-defined scopes, as it relies heavily on the accuracy and completeness of the plans and specifications.

2. Design-Build

Design-build is a method where the owner enters into a single contract with a design-build team, consisting of both the designer and contractor. This approach streamlines the process by having one entity responsible for both the design and construction phases of the project.

Advantages

One of the main advantages of DB is its potential for time and cost savings. By eliminating the bidding process, there can be more efficient communication and decision-making between all parties involved. This can result in faster project completion times and potentially lower costs due to reduced change orders.

Another benefit of DB, especially relevant in project management for architects, is that it allows for greater collaboration between the designer and contractor. With everyone working together on the same team from start to finish, there is more opportunity for innovation and problem-solving. This can lead to more creative and efficient solutions for design challenges, ultimately resulting in a better end product.

From a client’s perspective, DB also offers a simplified experience. Instead of having to manage multiple contracts and communication with separate entities, the client only needs to work with one team. This can save time and reduce stress for the client, making the entire process more enjoyable.

Disadvantages

It’s important to note that while DB has many benefits, it may not be suitable for every project or client. For larger projects or clients who have specific requirements and preferences, traditional design-bid-design may still be the preferred method. Other downsides include potentially higher costs and less control over the design process.

3. Construction Manager At Risk

The Construction Manager at Risk is a project delivery method where a construction manager is engaged during the design phase to collaborate with both the design team and the project owner. This manager plays a pivotal role in providing valuable constructability reviews, cost estimates, and project management insights. One of the hallmark features of CMAR is the establishment of a Guaranteed Maximum Price (GMP), which the construction manager commits to, thereby assuming the financial risk of exceeding this cost ceiling.

Advantages

There are several advantages to the CMAR method, which are also significant in the context of construction risk management. Firstly, risk management is significantly improved as the construction manager takes on the responsibility of keeping the project within the GMP, offering financial predictability to the owner. Additionally, the early involvement of the construction manager enhances quality control and allows for more accurate cost forecasting. This method fosters enhanced communication, as the construction manager acts as a mediator between the design team and the contractors, leading to smoother information flow and reduced conflicts. 

The CMAR approach is also known for its time efficiency. Construction activities, such as site preparation, can commence while the design is still being finalized, expediting overall project completion. Moreover, this method provides flexibility, permitting adaptive changes during the construction process without significant delays or cost escalations.

Disadvantages

However, the CMAR method comes with its set of disadvantages. It can potentially lead to higher initial costs due to the early involvement of the construction manager. The lack of competitive bidding in the early stages may result in missed opportunities for cost savings. The success of the project heavily depends on the construction manager’s expertise, making their selection a crucial decision. 

The contractual relationships in CMAR can be more intricate compared to traditional methods, necessitating careful management and a comprehensive understanding by all parties. Finally, once the GMP is established, there might be limited scope to benefit from favorable market conditions that could otherwise reduce costs.

4. Construction Management Multi-Prime

In this model, the owner contracts directly with multiple prime contractors to oversee different portions of the project. This can include everything from the foundation and structure to plumbing and electrical work. The idea behind this method is that by dividing up responsibilities among specialized contractors, the project will run more efficiently and be completed faster.

Advantages

There are several advantages to the CMMP approach. It allows for specialized expertise in each segment of the construction, as contractors focused on specific areas bring high levels of quality and efficiency. This method gives the owner greater control over the project, with the ability to directly oversee and communicate with each contractor.

 CMMP is also characterized by its flexibility, as it can adapt to changes more easily, with the owner having the freedom to select contractors for each phase based on current needs. Competitive bidding for each segment can lead to potential cost savings, as specialized contractors might offer more attractive bids for their expertise. Additionally, the distribution of risk among various contractors can mitigate the impact of problems in one area on the overall project.

Disadvantages

However, CMMP comes with its set of challenges. Coordinating multiple prime contractors requires significant effort and strong communication skills, presenting a complex management task. The owner faces increased responsibilities in managing contracts and resolving conflicts among contractors. If not managed effectively, the involvement of multiple contractors can lead to scheduling conflicts and project delays. 

There’s also a risk of inconsistencies in work quality and project vision, as different contractors might have varying standards and interpretations. The complexity of managing diverse relationships and logistics under CMMP demands a high level of expertise and experience from the construction manager.

5. Public-Private Partnership

This type of project delivery method involves a partnership between a public entity, such as a government agency, and a private organization, typically a construction company or developer. The goal is to achieve the best possible outcome for both parties by combining their strengths and resources.

Advantages

One of the main benefits of a public-private partnership is financial flexibility by introducing alternative funding sources for public projects, thereby reducing the financial strain on government entities. 

Risk sharing is another significant benefit, as it leads to more comprehensive risk assessment and management strategies. The involvement of private companies, driven by profit and performance considerations, often results in higher quality outcomes and operational efficiency. Additionally, P3 arrangements can expedite project completion due to the private sector’s streamlined processes and the reduction of bureaucratic holdups typically associated with public projects.

Disadvantages

However, one of the major downsides is that the process of establishing a P3 agreement can involve intricate and prolonged negotiations, which might delay project initiation. There’s a concern that private sector entities might place profit above the public interest, potentially affecting service quality or accessibility. 

P3 projects usually entail long-term commitments, which pose risks in the face of changing project needs or economic conditions. Balancing the public’s need for transparency with the private sector’s confidentiality can create issues regarding transparency and accountability. Furthermore, dependence on private companies for essential services can be problematic, especially if a company encounters financial issues or fails to meet established performance standards.

6. Integrated Project Delivery

Finally, there is another delivery method known as Integrated Project Delivery. This approach involves collaboration between all stakeholders, including the owner, architect, contractor, and subcontractors. The goal of IPD is to create a more efficient and collaborative construction process by involving all parties from the start of the project.

Advantages 

Major advantages include improved communication, reduced conflicts and claims, and increased accountability among all parties involved. With IPD, everyone has a stake in the success of the project, which leads to a shared goal and commitment to delivering high-quality work.

Disadvantages

The downsides of this method include the initial time and resource investment required to establish trust and communication channels between all parties. However, these potential roadblocks can be mitigated through effective project management and open communication.

IPD is a great option for projects that are complex and require a high level of collaboration, such as healthcare facilities, educational institutions, and large commercial buildings. By involving all parties from the beginning, IPD can help avoid delays and cost overruns that often occur in traditional construction methods.
