Grooved Construction Reduces Field Manhours
Total Field Manhours
Civil / Structural

Electrical
Piping
Large Component of Total Manhours
Grooved Construction Reduces Risk & Contingency
“Variable” Costs• Risk-Intensive
• High Contingency Factors
• Exposure
"Fixed" vs. "Variable" Costs - Welded
Labour“Variable” Costs: 60%
Material“Fixed” Costs: 40%
WELDED
“Fixed” Costs• Reduced Risk
• Low Contingency Factors
• Reduced Exposure
GROOVED"Fixed" vs. "Variable" Costs - Grooved
GROOVED
Material“Fixed” Costs: 60%
Labour“Variable” Costs: 40%
Grooved Method History British War Department sought faster way to join pipe in WWI
– Rapid deployment of water and fuel to front lines
– Faster than welding or threading
VICTAULIC company name– “VICTory Joint” for use on hydrAULICs

Schedule Impact with Grooved Construction
Case StudyPortlands Energy Centre
Toronto, Ontario, Canada
Portlands Energy CentreToronto, Ontario, Canada
• Challenged with schedule restraints
• Allocated available welders for P91 systems, pipefitters for grooved systems
• Press system allowed for two-person crew team, rather than three-person team
• Plant was delivered ahead of schedule
