Study Notes
Life Cycle Cost vs. Simple Payback Analysis
- Life Cycle Cost (LCC): Considers all costs associated with an asset or project throughout its entire lifespan, including initial investment, operating expenses, maintenance, repair, replacement, and eventual disposal.
- Simple Payback Analysis: Determines the time it takes for a project's total investments to be recovered from its net cash inflows. It only considers upfront costs and the expected benefits over a set period, neglecting future costs and savings beyond the payback period.
- Key Difference: LCC is more comprehensive, considering the entire project life, while simple payback analysis focuses solely on the initial investment recovery period. LCC provides a broader perspective, allowing for more informed decisions, while payback analysis is simpler and quicker.
Divisions (21, 22, 23)
- Division 21: Focuses on or encompasses the planning, design, or the conceptualization stage as a whole.
- Division 22: Involves the mechanical systems of a building or project, such as heating, ventilation, air conditioning (HVAC), plumbing, and fire protection. Often this encompasses a significant portion of a construction project.
- Division 23: Typically associated with the electrical systems within a building or project, including power distribution, lighting, and communications systems.
Mechanical Contractor vs. General Contractor
- Mechanical Contractor: Specializes in the installation and maintenance of mechanical systems like HVAC, plumbing, and fire protection. They are experts in those specific trades but aren't responsible for the whole building project's construction.
- General Contractor (GC): Oversees the entire construction process, coordinating all phases of the project, from foundation to finish. A GC manages multiple trades, including mechanical contractors. A GC, typically handles the planning, budgeting, scheduling, and general oversight.
- Key Differences in Responsibilities: A mechanical contractor handles only mechanical systems, while a general contractor handles everything.
- Relationship: Often, a GC hires specialist contractors (like mechanical contractors) to complete certain parts of the project. They are partners in achieving the project goal under overarching direction of the General Contractor.
