1. A new building is being constructed and the following tasks are required. The normal workdays are 7am-3pm, Monday to Friday. Overtime is possible, however the costs make it highly underiable. Write a Gantt chart for completion of the job in 3 months.

Site Preparation - 1 month

Foundations - 1 month - after Site Preparation

Framing - 2 weeks - after Foundations

Plumbing - 5 weeks - after Framing

Electrical - 6 weeks - after Framing

Inspection - after Plumbing and Electrical

Drywall - 2 weeks - after Inspection

Painting - 1 week - after Drywall

Hardware - 1 week - after Painting

Carpet - 3 days - after Painting
