“Integrated Project Delivery with a Lifecycle assessment” (IPALa)

Integrated Project Delivery (IPD) is a collaborative project delivery model that aligns the interests of all participants through shared risks, rewards and joint decision-making.
In Germany, its application is still emerging, particularly in public construction projects.

This research project extends the IPD approach by integrating a life cycle perspective (IPALa), with a particular focus on incorporating operational requirements into early project phases. While conventional IPD projects typically conclude with the completion of construction, this approach aims to systematically include the operational phase in project objectives, decision-making processes and incentive structures.

The project investigates how operational considerations can be embedded into collaborative delivery models to improve long-term performance, sustainability and economic efficiency.
A key aspect is defining an appropriate time horizon for the operational phase and developing incentive mechanisms that ensure alignment of interests among stakeholders over this extended period.

The research contributes to advancing project delivery structures through innovative approaches that enable more sustainable, performance-oriented and economically viable construction projects.
