“…Off-site operations are undertaken by trades with individual specialisations often without the necessary coordination to prevent work starvations in the production system. In other words, there is currently not much difference between onsite and off-site construction processes and initiatives used in other production settings such as integrating processes and cross-training have not yet been implemented in the prefabricated construction sector [10].…”

“…All three organisations reached a level in Captial Cost which is usually one of the most significant barriers to OSC as it tends to require higher up-front costs for the purchase of materials at the beginning of a project (Mtech, 2009). Once this initial investment has been absorbed into organisational business models, organisations should look for other available opportunities and joint ventures to achieve the economies of scale (Arif et al, 2012). On the other hand, organisations B and C have achieved level three in cost certainty and time certainty.…”

Purpose This paper aims to present factors affecting the Indian construction organisations in adopting off-site construction (OSC) methods. Design/methodology/approach An existing readiness maturity model has been used to assess three large organisations in different parts of India. A case study methodology has been adopted in this paper to highlight critical issues in OSC adoption in India. Findings This paper presents three case studies and concludes the Indian construction sectors readiness to adopt the OSC methods. Through the case studies, different issues related to the adoption of OSC have been identified and highlighted for the Indian construction sector. Although the three companies are large, there are several small- and medium-sized enterprises (SME) operating in India's construction sector, and future research shall be needed to review these SMEs. Research limitations/implications This research study is broadly focused on developing and assessing an OSC readiness framework for Indian construction organisations. The research scope and the population for data collection are limited to large construction organisations in India only. Practical implications The proposed OSC readiness maturity model guides construction practitioners in India through a structured process to assess their OSC readiness in the market. This assessment enables them to evaluate and benchmark their processes through the strategic and operational phases. This research will add to the existing knowledge of OSC in India by mapping issues relevant to India's construction industry. The research has provided background on the status of OSC, the drivers and barriers affecting the implementation of OSC techniques in the Indian construction industry. Originality/value Through the three case studies, several factors related to the implementation of OSC methods have been identified and highlighted within the Indian construction sector. Although the model has been applied to the Indian construction sector, it can easily be modified to fit into other areas and similar dynamics and business conditions.

“…These differences in the manufacturing and construction practices in terms of WBS, however, have brought their own issues in the attempt to plan a smooth interface between the manufacturing and construction processes in offsite construction projects. Among various aspects identified as priorities in implementing offsite construction techniques, synchronising construction processes and activities with that of the manufacturing as well as better linking manufacturing schedules to actual construction processes have been considered high priority to be resolved (Arashpour et al 2018;Arif et al 2012). Incompatibilities in offsite construction projects that have been reported mainly stemming from the difficulties to synchronise the manufacturing activities that are repetitive in nature and in a highly controllable environment with the onsite construction tasks that are typically unique and carrying high uncertainty and variability in delivery (Salama et al 2016;Harris and Ioannou 1998).…”

“…Thus, this particular case study has provided evidence that this "black box" approach is a common approach in the construction industry and further discussion has pointed out that within the context of offsite construction projects, the product oriented WBS is needed mainly to manage the offsite manufacturing processes but the activities oriented version of the WBS should also be prepared to synchronise the entire project in a holistic manner. This synchronisation between manufacturing schedules to actual construction processes have been considered high priority in the further development of offsite construction to be resolved (Arif et al 2012).…”

“…On the other hand, in executing construction site activities, the construction's WBS typically shows the site activities to be undertaken by the main and subcontractors (Winch and Kelsey 2005). This incompatibility between the WBS systems in the manufacturing based and construction based activities has potentially resulted in a less seamless interface and integration between them, which has been considered as one of the weaknesses and hence criticisms of the offsite construction projects (Arashpour et al 2018;Arif et al 2012). Attempting to address this issue, the research project reported here proposes WBS-matrix especially developed for offsite building projects as the potential solution.…”

Offsite construction techniques continue to receive considerable attention in academic/research discourse. Currently, offsite techniques still require a certain portion of construction works to be conducted onsite; albeit with a significant proportion delivered in a controlled offsite environment-typically in manufacturing facilities. Whilst discourse in seminal literature critique the positive and negative aspects of offsite; on balance, the benefits outweigh the barriers, especially when fully integrated and managed. From a management perspective, the project management techniques typically applied to offsite construction projects typically commence in determining the work breakdown structure (WBS) of these projects. Whilst the WBS approach originated from the manufacturing and engineering domain, this approach is equally applicable to offsite deliverables, reflecting site-based construction activities and concomitant dependencies with the manufacturing processes. However, there are slight discrepancies in processes, and equally, some areas of repetition and duplication. This mismatch has a fundamental impact on integration, creating pockets of confusion, where less seamless (sub-optimal) synergy between offsite and onsite works is lost. This is an acknowledged challenge. Even in cases where the WBS of the manufacturing side was converted into activities to facilitate synchronisation, precise information of the 'product' is still needed. There is therefore a real need to retain the product breakdown structure, particularly the manufactured portion of the works; but, at the same time, ensuring a seamless interface with the onsite works is maintained. This is a challenge. Whilst the WBS-matrix has been implemented in the project management domain to bridge the 'products' and 'activities', this arrangement has not yet been developed for offsite building construction projects. This paper reports an ongoing research project set up to implement WBS-matrix for offsite construction projects. Two cases of recently completed offsite construction building projects were used in a case study setting to analyse current practices-to inform the way forward to further develop the WBS-matrix. Findings from this research provide clear guidance for practitioners involved in offsite construction projects; particularly on the development of the WBS-matrix for manufacturing deliverables/activities in order to more effectively manage offsite construction projects.
