It is mainly established by work measurement methodology giving the time allowed to an operator to carry out a specified task under specified conditions and defined level of performance. This definition may be with respect to a task (a job element or an activity) or a product (consisting of many tasks). In the latter case, which is the main thrust of this work, as one job element passes through different resource (work) centres, another job element of subsequent ones will immediately follow and this will continue until the last job element is completed as a whole, this means value added at each work centre. This scenario will affect the level of inventory in the system and the level of inventory in the system depends on the type of production system and configuration (series, parallel or a combination of both) adopted. This too will affect the standard time for a single product (one-off), single product (mass produced), mixed or different products which may utilize assembly line philosophy and products in batches even with backtracking. Different examples have been used to highlight this scenario with different approaches developed which have gone a long way to improve on the solution techniques of the existing models.

The study was guided by the technology acceptance model (TAM) theory. The study used a descriptive research design method of investigation, and a simple random sampling technique was used to select a sample size of 123 from a population of 194 practitioners using the Krejcie and Morgan's method of sample size determination. The data collection and survey instrument included a well-structured questionnaire, discussions, personal observations and visits to elicit information from respondents/construction project locations. The collected data was presented in the form of frequency distribution, figures, and charts using descriptive statistical tools using IBM SPSS Statistics version 25.0. The study's findings indicate a general low level of utilization/application of Blockchain technology in the delivery of construction projects in Imo state. This is due to the fact that none (0.00%) of the respondents have heard of Blockchain technology as applicable to construction projects-related activities, 9 (10.47%) have used Blockchain technology sparingly, 35 (40.70%) have never heard of Blockchain technology and 42 (48.84%) have heard of Blockchain technology, but never applied it on any construction project-related activity out of the eighty-six (86) responses used for the study. This study recommends that, a united front is needed to make Blockchain technology awareness-raising and encourage practitioners to embrace it. Blockchain can provide a dependable infrastructure for information management throughout all stages of the construction project life cycle as well as secure storage of sensitive sensor data.

Prior to the introduction of BIM, the construction industry was confronted with obstacles and was sluggish in adopting change. Until recently, existing BIM research has mostly focused on large enterprises and there has been an apparent pattern of underrepresentation of medium-sized firms in BIMrelated studies. Thus, the purpose of this article is to investigate the major hindrances to BIM's adoption in construction projects as well as the dynamics of these hindrances in a developing country like Nigeria, using the total interpretive structural modelling (TISM) approach. The TISM displayed an 11-level hierarchy of hindrances made up of independent, dependent and linkage categories. Based on the Matrice d'Impacts Croises Multiplication Appliqué a Classement (MICMAC) analysis, "Lack of skilled BIM personnel" had the highest driving and the lowest dependence (independent) power, thus indicating its importance in the adoption of BIM. The findings further showed that "Lack of awareness of BIM" and "Resistance to change" are critical for the adoption of BIM in construction projects. The drivers (dependents) for the ease of adoption of BIM by policymakers and practitioners within the built industry are thus defined in this study. This study contributes to the early studies of BIM adoption from a developing country's perspective.

The study further sought to address the reasons why Total Quality Management implementation would be of immense benefit to environmental sustainability as well as how to sustain an environment that meets today's needs without compromising the needs of the future generation. In achieving the objectives, a survey comprising a sample of 122 respondents using structured questionnaires was conducted using the Federal Environmental Protection Agency in Nigeria as case study. The questionnaire sought the respondent's views on the implementation of Total Quality Management for Sustainable Development. The data for the study were analyzed using descriptive statistical tools like frequency, pie chart and bar chart. Furthermore, the findings of the research revealed that the Federal Environmental Protection Agency has been in operation all this while but lacks the plan to implement Total Quality Management and quality related policies for purposes of achieving Sustainable Development. Finally, the research articulated the efforts of the Federal Environmental Protection Agency in striving to achieve a sustainable environment; hence the study concluded that the Deming's Plan Do Check Act (PDCA) and Define Measure Analyse Improve Control (DMAIC) Six-Sigma should be inculcated in their strategic plans for purposes of achieving sustainable development.

However, many problems especially in the areas of project management appear to have defied linear programming approaches in the search for optimal solution even though many have continued to use the technique without any verification as to the authenticity of the solution. Two of such cases earlier studied exhibited this tendency – the capital rationing problem as well as that of time/ cost trade-off analysis. The problem seems to lie at those assumptions associated with model formulation, which necessitated the use of linear programming in the first instance. This paper is an attempt to look into the historical perspective with a view to eliciting more comments and researches for a more appropriate solution especially in an industrial setting.

The data for the study was collated from 78 out of 150 graduates of Federal University of Technology, Owerri, Nigeria. Data was collated via questionnaires using the surveymonkey medium via email to the respondents. Microsoft excel was used in analyzing the descriptive statistics from the study. The findings from the study revealed that 91.9% of the respondents did envisage the idea of ICD/DCP as relevant to professional career advancement. While most graduates received training on IDP/CDP after graduation than as undergraduates. The study finally recommends professionals in HRD to incorporate aspects of IDP/CDP in student's curriculum so as to enable them create a niche for themselves in terms of career planning and development.

The research approach deployed for this study includes targeting purposively selected construction firms that are involved in GSCM in construction related projects in Imo State, Nigeria. A questionnaire survey was deployed amongst a sample of construction firms. Barriers to GSCM implementation were identified via an extensive literature review. Specifically, data for the study was acquired via questionnaires from relevant industry practitioners. The study was limited to construction firms that are involved in GSCM related activities within Imo State which is located within the high construction /'Niger Delta' hub of Nigeria. With the limited nature of the study in terms of geographic coverage, the results from this study can be extrapolated to cover other parts of the country. The findings revealed that barriers to GSCM implementation were mostly lack of knowledge and experience which headed the list of barriers as stated by the respondents. This is followed in that order by lack of top management support, cost of implementing GSCM, lack of government regulations and support systems amongst others were ascertained to be obstacles to GSCM implementation in Imo State. The study concludes by recommending that a more detailed analysis be carried out with a view to building the capacity of practitioners in GSCM pursuant to better construction project performance.

Secondary data of selected building elements of public storey building projects completed within a 10 year period of 2009 and 2018 are obtained for this study. This consists of cost data of 240 projects retrieved from archives of building construction contractors. Data collected which include production costs of materials, labour, plant and equipment of the selected building projects are analyzed using descriptive statistics and analysis of variance (ANOVA). Results of the study indicate that production cost of materials is highest while cost of equipment is the least among the selected building. Window and door elements have the highest cost of materials at 77.17%; staircase, floor and upper floor elements have the least cost at 52.98%. Mechanical installations and finishing elements have the highest production cost of labour at 35% while windows and door elements have the least total elements cost of 20.49%. Framework has the highest proportion of cost of equipment of 15.02% and the least is windows and door elements at 2.34%. The proportion of production costs are 52.98% to 77.17%, 20.49 to 35% and 15.02% to 2.34% for material, labour and equipment components respectively. The study establishes that the proportion of the selected components of the building elements are not the same across the selected elements evaluated (p-value < 0.05). The study recommends the adoption of the results of this study in ensuring accuracy of estimation of construction building projects.

The research approach deployed for this study includes targeting purposively selected construction firms that are involved in GSCM in construction related projects in Imo State, Nigeria. A questionnaire survey was deployed amongst a sample of construction firms. Barriers to GSCM implementation were identified via an extensive literature review. Specifically, data for the study was acquired via questionnaires from relevant industry practitioners. The study was limited to construction firms that are involved in GSCM related activities within Imo State which is located within the high construction /'Niger Delta' hub of Nigeria. With the limited nature of the study in terms of geographic coverage, the results from this study can be extrapolated to cover other parts of the country. The findings revealed that barriers to GSCM implementation were mostly lack of knowledge and experience which headed the list of barriers as stated by the respondents. This is followed in that order by lack of top management support, cost of implementing GSCM, lack of government regulations and support systems amongst others were ascertained to be obstacles to GSCM implementation in Imo State. The study concludes by recommending that a more detailed analysis be carried out with a view to building the capacity of practitioners in GSCM pursuant to better construction project performance.

The study adopted an exploratory research design (quantitative and qualitative) methods. A purposive and convenient sampling technique was deployed with the aid of semi-structured interview, case study; questionnaire survey in a construction firm in Port-Harcourt, Rivers State, Nigeria. Questionnaires were used to collect primary data after being pre-tested via a pilot study for validity and reliability. The data collected were analysed using the AHP. Findings from the study shows that the following features are key; Instituting trust and long term relationships amongst supply chain partners (ITP), supply chain finance (SCF), supply chain and continuous performance measurement (SCCPM), information technology (IT), quality management (QM), supply base management (SBM), senior management’s commitment (SMC) and s...

Secondary data of selected building elements of public storey building projects completed within a 10 year period of 2009 and 2018 are obtained for this study. This consists of cost data of 240 projects retrieved from archives of building construction contractors. Data collected which include production costs of materials, labour, plant and equipment of the selected building projects are analyzed using descriptive statistics and analysis of variance (ANOVA). Results of the study indicate that production cost of materials is highest while cost of equipment is the least among the selected building. Window and door elements have the highest cost of materials at 77.17%; staircase, floor and upper floor elements have the least cost at 52.98%. Mechanical installations and finishing elements have the highest production cost of labour at 35% while windows and door elements have the least total elements cost of 20.49%. Framework has the highest proportion of cost of equipment of 15.02% and the least is windows and door elements at 2.34%. The proportion of production costs are 52.98% to 77.17%, 20.49 to 35% and 15.02% to 2.34% for material, labour and equipment components respectively. The study establishes that the proportion of the selected components of the building elements are not the same across the selected elements evaluated (p-value < 0.05). The study recommends the adoption of the results of this study in ensuring accuracy of estimation of construction building projects.
