Cost Reduction vs Constructability
Business ContextDesign simplification and reduced material quantities can lower estimated capital cost, but some savings can make installation more difficult, increasing field labor, lifting requirements, temporary works, or shutdown duration.
Brown Field Industrial Projects TRIZ ResolutionEvaluate cost at the installed-system level rather than through material or equipment price alone. Prefabrication, accessible connections, modular assemblies, and construction-friendly details can reduce both installed cost and field complexity.
Applicable TRIZ Principles
Principle 1 – Segmentation: divides installations into manageable construction modules.
Principle 10 – Prior Action: moves work from constrained field conditions into controlled preparation environments.
Principle 7 – Nested Doll: integrates assemblies to reduce separate field installation activities.
Expected Outcome
Lower installed cost
Improved constructability
Reduced field labor
Shorter execution duration
Decision IndicatorsEarly indicators that this contradiction is limiting project performance include:
Design savings increase field installation hours.
Low-cost layouts require complex temporary works.
Material savings create difficult connections.
Procurement savings increase shutdown work.
Constructability impacts are identified after design decisions.
Monitoring these indicators helps organizations reduce total installed cost rather than merely lowering individual design quantities.
