Design of Construction Production Processes: Framework and Conceptual Model

Development of a process reference model for construction supply chains

“…First, the contractor has to 'Determine project needs'. The objectives of cost, time, quality, productivity, and efficiency in construction projects vary from project to project (Thiengburanathum and Diekmann 2002). Not all projects need to be measured with the same KPI system.…”

“…In construction, production of the final product takes place on-site with the transfer of goods and resources to the worksite. Construction production theory considers information from owners and/or architects and resources as process inputs and construction objects as outputs (Thiengburanathum and Diekmann 2002). Ebel and Clausen (2007) recognise three categories of construction logistics: supply logistics to the construction site, site logistics and disposal logistics.…”

“…Resources in the construction site can be categorised in two double axes according to Thiengburanathum and Diekmann (2002): renewable (e.g. labour) / non-renewable (e.g.…”

“…principle, scilicet, ordering and deliveries take place when work is halted due to lack of required materials, a practice that leads to frequent delays, loss of time and additional costs caused by express deliveries. Lack of planning in advance and reactive practices can lead to insufficient ways of working and allows repetitive mistakes (Thiengburanathum and Diekmann 2002). This leads to a vicious cycle, as Sacks (2016) describes, that "insufficient or late supply of resources in turn increases the instability of the plan".…”

“…Another is the space available to crews to perform their tasks. Space is a resource used by one or more workstations and is a main point of differentiation between the construction and the manufacturing process (Thiengburanathum and Diekmann 2002). Dawood et al (2005) identify space as one of the main resources and constraints that affect the delivery of construction projects.…”
