Poor performance of the pre-construction stage will negatively influence the progress of following works, consequently impairing the overall project’s performance (Waly and Thabet, 2002; Kolltveit and Gronhaug, 2004).
Previous studies done to improve the pre-construction stage were not holistically envisioned and focused only in improving certain aspects within the stage (Freire and Alarcon, 2002; Hagstrom and Wollner, 2011).
The importance of addressing process complexity is undermined due to limited research found in this area. It is extremely critical to address process complexity as it is the root cause for subsequent problems (Hogan et al. 2012), as shown in the following diagram.

Aim To establish a conceptual framework that applies lean
thinking to reduce process complexity at the pre-construction stage.
Objectives To define process complexity To provide linkage between lean thinking, process
complexity and the pre-construction stage To propose lean based solutions to improve process
complexity at the pre-construction stage To demonstrate the application of the framework in real
project.

Empirical data gathering stages Stage 1: Case selection. Interview with project
manager and personnel involved in order to understand the flow of work at the pre-construction stage.
Stage 2: Conduct case study by collecting pre-construction records, documents, time, processes, participants, etc.
Stage 3: Data from case study is represented in the form of lean based mapping using Value Stream Map (VSM) and process map. Current map that represents the present processes is produced. Belayutham, S. (2014), Process complexity at the pre-construction phase: A lean based solution, Research
paper presented at the 4th New Zealand Built Environment Research Symposium (NZBERS), 14 November, Massey University, Albany campus.
Method of data analysis Data will be analysed based on the current map, to distinguish the
complexity of the system.
Metrics and measurement standard Control-Flow Complexity (CFC) metrics (Cardoso, 2006). Using an established equation, complexity of the processes could be
calculated and results will be in the form of a round figure. The higher the value, the more complex the processes are.
Lean government metrics (US EPA, 2009). Variables include: Lead time, process steps, decisions, delays,
handoffs and loops. The occurrence rate of those variables will be determined from the
current map and lean based strategies will be proposed to reduce the amount of those waste.

Preliminary and Anticipated Results
Objective 1 Process complexity is defined with adoption from Business Process Management
(BPM). The metrics and measurement standards were later derived from BPM based
Control-Flow Complexity metrics and lean government metrics. The metrics and measurement standards will be used to assess complexity in
processes quantitatively. Objective 2 The establishment of relationship between lean thinking, process complexity and
pre-construction stage enables the pre-construction complexity to be viewed from a lean perspective, subsequently improving the system using lean approaches.
Objective 3 Lean based solution to improve the current processes is derived in relation to the
11 lean principles. Objective 4 The framework is modelled based on real case study. Quantitative value of
complexity on real project can be expected and future improved state is anticipated with recommended improvement strategies that abide the lean principles.

Significance of Research Theoretical
Introduced the perspective of process complexity as a waste, from the administration waste stand point.
The established metrics and measurement standards allow for rich and comprehensive understanding of complexity within the current state.
Practical Allows identification and improvements to be made for the commonly
neglected aspect of process complexity. Positive improvements taken to address the root cause (process
complexity) will have positive influence on other aspects of work that eventually increases project’s performance.
