LSTK vs LSPB: Choosing the Right Contract Model

Selecting the right contracting strategy is crucial to managing project risk, scope, and value in infrastructure and industrial projects.

1. Scope Responsibility

LSTK includes design, procurement, and construction; LSPB excludes design and focuses solely on procurement and construction deliverables.

2. Risk Allocation

LSTK transfers most project risk to the contractor; LSPB shares more risk with the client, especially during the design stage.

3. Client Involvement

LSTK reduces client input post-award; LSPB requires client oversight and coordination during the design-to-procure interface phase.

4. Delivery Flexibility

LSTK offers a single point of accountability; LSPB allows more control and flexibility, especially when design is client-driven or evolving.
