General Contractor: Definition, Roles, and Common Forms

In the modern construction industry, “general contractor” has become a familiar term, holding a central role in all major projects, from industrial and commercial buildings to infrastructure. Clearly understanding the concept, roles, and various forms of general contracting and especially selecting the right professional general contractor like DaiDung Group is the key to success for every project.

Introduction and Definition of a General Contractor

A General Construction Contractor is an organization or company that undertakes all stages of a project under a contract signed with the project owner. This includes everything from design, construction, and supply of materials and personnel to the completion and handover of the project. According to Vietnam’s Law on Construction, a general contractor can undertake one or more significant parts of a project, depending on the contract type and project scale. Unlike a prime contractor or subcontractor, the general contractor holds a comprehensive coordination and management role, bearing overall responsibility for the quality, schedule, and safety of the project.

The Role of a General Contractor

A general contractor does more than just construction; they also act as a consultant, manager, and organizer, ensuring the project is executed synchronously and scientifically. Specifically, a general contractor performs the following main tasks:

• Overall Project Management: Overseeing the entire process from design and material procurement to construction and project completion.
• Planning, Construction Organization, and Subcontractor Coordination: Optimizing resources and sequencing work to ensure the overall project schedule and quality are met.
• Ensuring Schedule, Quality, Safety, and Cost Optimization: Applying modern management methods to minimize financial, technical, and labor safety risks.
• Responsibility for Materials, Manpower, Equipment, and Services: Proactively preparing and supplying all necessary resources, from personnel and materials to machinery and equipment, to meet stringent project standards.

The central role of the general contractor helps the project owner save time, optimize costs, and control risks throughout the project’s lifecycle.

Common Forms of General Contracting

1. Design Contractor A Design Contractor is responsible for the entire design phase of a project, from initial concept development and surveys to completing detailed drawings for architecture, structure, MEP (Mechanical, Electrical, Plumbing), technical systems, and other items. The role of a design contractor extends beyond creativity to ensuring feasibility, compliance with legal regulations, and optimizing the functional use of the structure.

• Plans the design and develops concepts based on the project owner’s requirements.
• Completes detailed drawings, including architecture, structure, and technical systems (electrical, water, ventilation, fire protection).
• Advises on suitable materials and construction methods to ensure quality and longevity.
• Coordinates with relevant parties to ensure synchronization and avoid conflicts during the design process.

2. Construction Contractor A Construction Contractor undertakes all construction work based on approved design drawings and technical documents. They are responsible for turning the design concept into reality, managing the entire construction process from site preparation to completion and project handover.

• Creates detailed construction plans, including resource allocation (manpower, materials, equipment) and schedules.
• Organizes and directs construction activities on-site.
• Manages quality, schedule, and labor safety throughout the construction process.
• Coordinates with subcontractors, suppliers, and other stakeholders.
• Conducts acceptance testing and hands over the completed project to the owner.

3. Design & Build Contractor The Design & Build (D&B) model combines both design and construction into a single contract, managed by one general contractor or a joint venture. This model helps the project owner minimize risks and optimize time and costs due to the close coordination between the design and construction phases from the very beginning.

• Executes all design and construction work under a single contract.
• Ensures the synchronization and feasibility of the design with the construction process.
• Proactively manages and resolves issues that arise, optimizing workflows.
• Helps the project owner save time and costs associated with project management.

4. EPC (Engineering, Procurement, and Construction) Contractor An EPC Contractor is a comprehensive form of general contracting that includes three main stages: Engineering, Procurement, and Construction. This model is often applied to large-scale, complex projects.

• Engineering: Performs all design work, including basic design, detailed design, and technical calculations.
• Procurement: Purchases and supplies all necessary materials and equipment for the project.
• Construction: Carries out all construction, installation, commissioning, and initial operation activities.
• Ensures the project is completed on schedule, within budget, and to the required quality.

5. Turnkey Contractor A Turnkey Contractor is the most comprehensive form of general contracting, where the contractor handles all stages from surveying, design, construction, material supply, and equipment installation to operational training and handing over a fully completed project to the owner.

• Manages the entire project lifecycle from A to Z, including investment project planning, surveying, design, procurement, installation, construction, testing, and training.
• Bears full responsibility for the final outcome of the project.
• Minimizes the project owner’s burden of managing and operating the project.
• Often used for projects where the owner has limited experience or management resources.
