Understanding Construction Management vs. General Contracting

When planning a capital improvement project, one of the first decisions an agency must make is how to structure project delivery. Understanding the differences between construction management and general contracting is essential for making the right choice. ## What is General Contracting? In a traditional general contracting arrangement: - The owner contracts directly with a general contractor - The GC is responsible for delivering the completed project - The GC manages subcontractors and suppliers - The owner's involvement is typically limited to approvals **Advantages:** - Single point of responsibility - Fixed price (in lump sum contracts) - Contractor assumes construction risk **Disadvantages:** - Owner has limited visibility into construction process - Changes can be expensive - Potential for adversarial relationships ## What is Construction Management? Construction management adds a layer of professional oversight: - The owner engages a construction manager as their representative - The CM oversees the contractor on behalf of the owner - The CM provides independent quality assurance and cost control - The owner maintains greater visibility and control **Advantages:** - Independent oversight protects owner interests - Early identification of issues - Better cost control and change order management - Improved documentation and risk management **Disadvantages:** - Additional cost for CM services - Requires coordination between CM and contractor ## When to Use Construction Management CM is particularly valuable for: 1. **Complex technical projects** - Water treatment, desalination, advanced infrastructure 2. **High-value projects** - Where the cost of problems exceeds CM fees 3. **Public projects** - Where accountability and documentation are critical 4. **Projects with tight schedules** - Where delays have significant consequences 5. **Multi-phase programs** - Where consistency across projects matters ## The Hybrid Approach: CM at Risk Some projects use Construction Management at Risk (CMAR), where: - The CM provides pre-construction services - The CM then takes on contractor role with a guaranteed maximum price - This combines early CM involvement with contractor accountability ## Making the Right Choice Consider these factors when choosing your approach: | Factor | General Contracting | Construction Management | |--------|--------------------|-----------------------| | Owner involvement | Lower | Higher | | Cost visibility | Limited | Transparent | | Risk allocation | Contractor | Shared | | Flexibility | Lower | Higher | | Documentation | Basic | Comprehensive | For most public infrastructure projects, adding construction management oversight provides value that far exceeds its cost through better quality, fewer changes, and stronger documentation.
