This is an example of a construction project. The construction for a large corporate building must be started by February 19th and completed by the end of the year. The legal contract for the project includes a penalty of $10,000 for every week of delay beyond December 31st. This implies 315 days or 45 weeks for the expected project duration assuming a seven-day work schedule and no holidays in between! The details of the project activities are as follows - The project begins with clearing the site, an activity that takes eight weeks. Once the site is cleared, laying of the subsurface drainage takes another eight weeks, followed by filling of the earth which takes 14 weeks. Only after this activity is completed can installation of the artificial turf outside of the building can start - the task then takes 12 weeks. Simultaneously, the work on the building can also start once the site is cleared. The work on the building starts first by excavating and then by pouring of the concrete basement. Each of these activities takes 4 weeks to complete. Next comes the construction of the walls (12 weeks), followed by constructing the roof (13 weeks). The interiors
