Before starting a construction project, consider factors like budget, design, permits, materials, timeline, and hiring experienced professionals to ensure smooth execution.

The duration depends on the project's size and complexity. Small renovations may take weeks, while large commercial projects can take months or even years.

Concrete, steel, bricks, and high-quality wood are commonly used for durability. The choice depends on the project type and environmental conditions.

Optimize the design, use energy-efficient materials, hire experienced contractors, and plan well in advance to avoid delays and extra costs.
