Project Delivery Methods Overview

Project Delivery Methods

• Project delivery methods define the structure of relationships, responsibilities, and communication among all project team members during a project.
• This structure is critical for smooth project execution and ensures project goals are met effectively.

Key Project Delivery Methods

1. Design-Bid-Build (DBB)

• Definition: The project owner contracts a designer for the design phase and separately hires a contractor for construction based on competitive bidding.
• Example: A local government commissions an architectural firm to design a school. After finalizing the design, contractors bid for the project, and the lowest qualified bidder constructs it.

2. Design-Build (DB)

• Definition: A single entity is responsible for both design and construction. This streamlines communication and speeds up project delivery.
• Example: A private developer hires a design-build firm to construct a shopping mall, ensuring quick decision-making and fewer conflicts between design and execution.

3. Construction Management at Risk (CMAR)

• Definition: The project owner hires a construction manager who commits to delivering the project within a guaranteed maximum price (GMP).
• Example: A university hires a CMAR firm to construct a library. The firm manages construction risks and ensures costs don't exceed the GMP.

4. Integrated Project Delivery (IPD)

• Definition: A collaborative approach where all key parties (owner, designer, contractor) share risks, responsibilities, and rewards to optimize project outcomes.
• Example: A hospital project uses IPD to align all stakeholders, ensuring the project stays on budget while prioritizing high-quality healthcare spaces.

5. Public-Private Partnership (PPP)

• Definition: A collaboration between a public entity and private sector firms for financing, designing, constructing, and operating a project.
• Example: A city partners with a private company to build and operate a toll road, where the company finances construction and collects tolls for a specified period.

Key Elements of Project Delivery Methods

1. Contractual Links

• Define responsibilities and accountability.
• Example: In DBB, the designer and contractor report separately to the project owner.

2. Communication Framework

• Ensure smooth coordination among stakeholders.
• Example: In IPD, all parties work collaboratively, reducing miscommunication.

3. Responsibility Distribution

• Clarifies roles of each stakeholder in the project.
• Example: In CMAR, the construction manager oversees risks and ensures cost control.

Benefits of Proper Project Delivery Methods

• Efficiency: IPD speeds up complex projects by aligning goals.
• Cost Control: CMAR ensures costs remain within the guaranteed maximum price.
• Flexibility: Design-Build allows adjustments during construction to meet project demands.

Key Roles and Relationships

• Principal: Represents the project owner or client.
• Design Consultant: Responsible for creating the project's design.
• Other Consultants: Specialists supporting the design process.
• Contractor: Responsible for constructing the project.
• Subcontractors: Oversee the work of subcontractors.

Types of Links

• Solid Line (Contract Link): Indicates a formal, legally binding contract.
• Dashed Line (Communication Link): Indicates an indirect working relationship requiring communication.

Procurement/Delivery/Contractual Methods

• These terms essentially refer to how a project is organized from start to finish, determining how contracts are established and who is responsible for what tasks.

Common Project Delivery Methods

1. Design-Bid-Build (DBB)

• Most traditional method where design by consultants, followed by contractors bidding for execution.
• Three phases: design, bidding, and construction.
• Example: School Project

2. Design-Build (DB)

• Single entity (design-build contractor) responsible for design and construction.
• Contractor works on design and construction simultaneously, reducing time.
• Example: Shopping mall project

3. Construction Management (CM)

• Construction manager acts as a consultant to the principal managing design and construction phases.
• Oversees multiple contractors and consultants, ensuring on-time delivery and within budget.

4. Public-Private Partnership (PPP)

• Private sector designs, builds, finances, and operates a public infrastructure project.
• Example: Highway construction project

5. Integrated Project Delivery (IPD)

• Highly collaborative approach where all stakeholders (principal, designer, contractor) share risks and rewards.
• Example: High-tech office complex

Choosing the Right Method

• Choice depends on factors like project complexity, time constraints, budget, and collaboration needs.
