The Productivity Basis of one hundred percent (100%) used in the book means the direct construction field labor workforce which produces 42 minutes of productive work out of each hour for a construction project having the following major characteristics:

• Grass Roots Chemical Processing Industry (CPI) processing facility using a proven design with one process train constructed in the U.S. Gulf Coast area
• USGC workforce supervised by an international contractor
• Non-Unionized direct hire workforce recruited from one local area labor pool near construction site
• Workforce having between 10 and 15 years construction experience
• Five day workweek, an eight-hour workday, and one shift per day
• Total direct field labor construction effort of approximately 100,000 USGC manhours
• Contiguous construction schedule after mobilization and prior to demobilization and start-up of 32 to 60 weeks
• Construction management performed by an independent firm for owner
• Prime Contractor having a backlog of less than three months work
• Prime Contractor has successfully completed previous projects for owner
• Fixed Price contract and no other work being performed by contractor near construction site
• All engineering work completed prior to the start of construction
• Quality of workforce supervision is good
• Moderate or low level of construction activity near the construction site during the construction period
• No construction work performed in operating areas
• No construction work performed wearing special safety clothing
• No strikes, labor disputes, or other outages or stoppages during construction
