Whenever construction work is being performed to a single-family residence or
a residential facility with (usually) less than 3 or 4 units. If you
are working on an apartment complex this would more likely be considered
a commercial project instead of a residential project. Similarly, if
you are working at a condominium, the work would be residential if upon a
single unit, but if on the entire complex or the common elements, the
work would more likely be considered commercial.Large-scale construction
requires collaboration across multiple disciplines. An architect
normally manages the job, and a construction manager, design engineer,
construction engineer or project manager supervises it. Those involved
with the design and execution must consider zoning requirements,
environmental impact of the job, scheduling, budgeting,
construction-site safety, availability and transportation of building
materials, logistics, inconvenience to the public caused by construction
delays and bidding. Large construction projects are sometimes referred
to as megaprojects.
