The ERP system has been identified as a tool for delivering information technology (IT) services through software and other critical infrastructures using internet technologies. Given its nature as an industry-driven concept and system, this is universally accepted in industry as a tool to solve practical problems with a view to achieving an integrated enterprise information system. However, a developing country like Nigeria still faces a lot of hurdles in managing its construction supply chain. The aim of this study is to investigate the factors affecting the successful implementation of enterprise resource planning (ERP) systems in the Nigerian construction industry. After a literature search, expert input via the Delphi technique, the study identified four main factors and 21 sub-factors. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was used to prioritise the factors and to identify the relationship that exists between the factors. The findings revealed that the key factors affecting the implementation of ERP systems are "A lot of security concerns" (T7), "The management of ERP projects is too complex" (P5) and "The inability to align the ERP solution with the business plans of the organisation" (P2). This study recommends that the findings of this work will help both local and international practitioners alike.

Combustion is one of the fundamental processes in learning and teaching in laboratories that leads to the release of gaseous pollutants that are both hazardous and a threat to the environment and health of individuals. This paper sought to measure the amount of combustion pollutants generated and their effects on the indoor air quality of a typical university laboratory using some selected laboratories in Ahmadu Bello University Zaria as a case study. The Combustion pollutants were measured using an IMR 1400C gas analyser. At the same time, its effects were assessed using a well-structured questionnaire designed and administered to hundred and twenty-seven laboratory users who were randomly selected. Data collected from the questionnaires were analysed using computer-based SPSS software. The results revealed that CO during combustion exceeded the ASHRAE 62 and NAAQS limit of 9ppm, reaching up to 45ppm at some points; also, oxygen was observed to be at a critical level of 20.9% and at some point falling below the limit to 20.4%. It was also observed that fatigue (RII: 0.81) is the most prominent symptom of poor indoor air quality during combustion, among other symptoms like coughing and sneezing, dryness and irritation of eyes and throat, sinus congestion, shortness of breath and headache, arranged in the order of intensity. The absence of functional fume hoods, laboratory congestion, and inadequate ventilation systems intensify the discomforting effect of combustion-generated pollutants in laboratories. Thus, it is recommended that fume hoods should be well maintained for functionality and installed in Laboratories where they do not exist (chemistry lab I). Finally, providing adequate ventilation systems in the laboratories would help increase safety in labs for learning and teaching purposes.  Keywords: Combustion Generated Pollutants, Indoor Air Quality, Measurement of Pollutants.

Aim: The aim of this study is to assess benefit of BIM as a collaborative knowledge management tool for construction professionals. Study Design: It was a mixed design research, the study was effected via literature review and a well-structured questionnaire. Likewise, interviews were carried out to substantiate the findings of the questionnaire survey. Place and Duration of the Study: The study was conducted in Kaduna State, Nigeria for a period of 2 years. Methodology: Being a mixed design research, a total of 250 questionnaires were administered and 235 were properly completed and returned representing a percentage response of 94%. Data garnered were analysed using relative importance index and presented in tables and charts. Results: The study found that 94% of construction industry’s professionals are familiar with the concept of BIM but 94.47% of them never applied it whereas 4.68% rarely apply BIM, while 0.85 often apply BIM. Also, the research identified that all the thirteen areas where BIM can be used as a KM tool for collaboration among construction professionals were significantly important, however, Constructability Reviews and 4D Simulations which involves providing an interface to visualize the entire structure and simulate the construction process stood out as the most important. Conclusion: The study concludes by recommending that the built environment professional bodies in Nigeria should carry out a proper sensitization programme in-order to train and retrain professionals in Nigerian construction industry as regards BIM tools and its applications. Also, BIM should be introduced as an integral part of the school curriculum for the training of future construction professionals so equipped them with the requisite BIM knowledge.

A disaster cause disruption to the normal patterns of life, as it is usually severe, sudden, unexpected, widespread, and has direct effects on the smooth running of an organization. This article has assessed the role of the facilities manager in disaster management in Lagos, with a particular interest in the pre-disaster measures provided. A quantitative research design using a well-structured questionnaire survey was adopted. Out of the 150 questionnaires distributed, a total of 134 questionnaires were returned duly completed, a response rate of 89.3 percent. The data were analyzed using the computer software SPSS (7th ed.). The result of the analysis revealed that the most common and reoccurring disasters experienced by companies in the study area were, as listed in their order of predominance, as follows: flooding, power outage, civil unrest, fire, and pest disasters. The study found that most firms rarely use the disaster threat information as part of their preparedness plan, nor has developed any disaster response techniques or recovery measures. The study has identified the major roles of a facilities manager in disaster management. These roles ranged from disaster record-keeping for subsequent planning, routine survey of areas prone to disaster, disaster tracking and warning, and public enlightenment on disaster occurrence. The study has recommended that facilities managers ensure that there is good public awareness, functional facilities, good organization and planning, and excellent functional readiness facilities, such as having emergency operations centers.
