Framework Analysis Conclusions Recommendations
Background
Background
• Constraints:
• August 26th, 2017 deadline
• Resource allocation
• Penalties
• Potential Risks:
• Approximately 10-week strike
• Harsh winter:
• Charge for pouring concrete

5. 5
Framework Analysis Conclusions Recommendations
Assumptions
Project:
• Project start date: June 6th, 2016
• No work on weekends
• No overtime
• Equipment and materials are out of scope
• Winter months: December, January & February

6. 6
Framework Analysis Conclusions Recommendations
Assumptions (con’t)
Construction:
• Footings require three weeks to cure
• Work that follows footings cannot begin until curing is complete
• Site preparation and foundation includes staging areas and traffic flow
redirection
• “Filling of the field” is assumed to be activity C, build field
• Tasks can pause midway through duration and resume at a later time

7. 7
Framework Analysis Conclusions Recommendations
Assumptions (con’t)
Employees:
• 67% of employees laid off during winter
• 15 employees during December, January and February, 30 for other months
• 5 employees utilized for management
• SCC hires unionized employees
• Strike begins when contract expires
Costs
• Projected net income of project: $450,000
• Indirect cost applied to alternate scenarios based off of do nothing benchmark
• Federal Holidays are insignificant

Conclusions
Conclusions
• 76% chance of a strike or a harsh
winter
• Expediting H decreases duration and
increases net income
• Incur the $22,000 charge
• Cut task duration from 10 to 6 weeks
• Best alternative:
• No obstacles
• Cold winter
