Development of Supply Chain Management Framework for Successful Construction Project Delivery in Nigeria.
The study explores and develops a supply chain management (SCM) framework for successful construction project delivery in Nigeria. Specifically, the study identifies the extent and level of awareness/adoption of SCM, evaluates key factors for successful SCM, as well as the factors constraining the adoption/application of SCM in the Nigerian construction industry. The study adopted a field survey and exploratory research design methods of investigation, while a purposive sampling technique was deployed in selecting the population size. The instrument for data collection and measurement were well structured standardized questionnaire modeled in Likert five point scales in addition to a semi-structured in-depth interview, multiple case study, and personal observations used in eliciting responses from construction firms located in Abuja, Lagos and Rivers State respectively. The questionnaires were pre-tested and validated for reliability. The data collected were presented using charts, figures and descriptive statistical tools, while the Relative Importance Index (RII), Severity Index (SI), and Analytical Hierarchy Process (AHP) were used in analyzing the major issues in the study with the aid of statistical tools in SPSS version 17.0 and Microsoft excel programmed software. The findings from the study show that there is a general low level of awareness /adoption of SCM as opined by 79.90% of the respondents. Findings from the evaluation of the eight (8) key factors for successful SCM indicate that disseminating quality information across the various chains (RII=1.16), deploying web based and other software and portals as well as the application of internet in enhancing the effectiveness of SCM in construction projects (RII=1.08) are the most important criteria. The findings of the study further revealed that the low level of adoption/application of SCM viz; lack of the understanding of SCM concepts (SI=50.76), unclear strategic benefits (SI=50.52), dearth of trust within and outside organizations (SI=50.31), lack of a common standard for collaboration (SI=49.32) and failure to broaden the supply chain vision beyond procurement or product distribution (SI=48.12) are the major constraints to SCM. While findings from the framework developed for SCM construction project delivery using the AHP indicates that the following are favourable and determining factors for successful SCM in construction project based on their Eigen value ranking; instituting trust and long term relationships among supply chain partners (28.26%), supply chain finance (18.93%), supply chain and continuous performance measurement (15.40%), information technology (9.92%), quality management (9.55%), supply base management (7.84%), etc amongst others. The study recommends that an awareness be created via professional associations platforms, while adequate attention and emphasis be accorded to quality information dissemination, deployment of web based portals, software and internet technologies, and that a forum be created through workshops, conferences and face-to-face interactions to aid in the application and understanding of what SCM construes in the successful delivery of construction projects.
