What is it about?

The paper demonstrates the needs to expand the system boundaries of construction project productivity (CPP) to reflect its systemic value and to shift the paradigm of CPP evaluation from being output-orientated and quantity-focused to being outcome-orientated and value-focused.

Why is it important?

The paper identifies three system boundaries for CPP evaluation, i.e., parameter, timeframe and stakeholder, and develops a two-stage CPP evaluation framework to indicate site efficiency and utilisation effectiveness thereby accessing the productivity of both the construction and post-construction stages. The “investment-in-failure” paradox associated with current CPP evaluation approaches is primarily attributed to the narrowly defined CPP boundaries. The research demonstrates the needs to expand the system boundaries of CPP to reflect its systemic value and to shift the paradigm of CPP evaluation from being output-orientated and quantity-focused to being outcome-orientated and value-focused. The systemic CPP conceptualisation and the two-stage CPP evaluation framework support the systems thinking of industry stakeholders and enable them to formulate holistic strategies for long-term CPP enhancement.

Perspectives

While the investment in construction projects has increased over the past few decades, low Construction Project Productivity (CPP) appeared to be persistent, thereby reflecting an “investment-in-failure” paradox between the investment and CPP. The authors of this paper hope that the developed systemic and holistic CPP evaluation framework could help to explain and resolve the apparent paradox in the construction industry.
