ABSTRACT
Purpose>Critical knowledge and lessons learnt from the delivery of infrastructure projects have often remained untapped mainly due to the transient and fragmented nature of construction delivery. The main aim of this paper is to investigate the mediating role of a project facilitator in attenuating disruptions in knowledge flows during the delivery of an infrastructure project.Design/methodology/approach>An inductive case-study method is employed in examining the mediating role of the facilitator in an infrastructure project. Content analysis was undertaken by coding the data derived from eight focus group interactions, 23 semi-structured interviews and 24 documentary sources from workshops using NVivo 12 plus.Findings>(1) The project facilitator provided a coherent context to re-invent the narratives (i.e. behaviours and events) by creating a forum for understanding critical problems and stimulating constructive dialogue and intervention. (2) The project facilitator leveraged on both explicit and tacit knowledge within the team, leading to improvement in the proactive management of emergent technical, operational and behavioural challenges, and (3) The project facilitator sustained a valuable intervention in attenuating disruptions in knowledge flows for problem-solving, relationship-management, best-practice strategies, coaching and leadership, as well as reflexive practice.Originality/value>The novelty of this research is that a facilitator is used as the “knowledge-broker” in a multi-party infrastructure delivery team assembled using a traditional lump-sum contract framework. Facilitators have only previously been used in collaborative contract environments like alliancing and partnering.
