It was a desktop survey as the study was effected via literature review and a direct observation and walkthrough evaluation. The study was conducted in SouthEast Nigeria specifically: Anambra, Imo, Enugu, Abia and Ebonyi for a period of 6 months. There are two methodologies used in this paper. The first is reviewing secondary data in order to develop the conceptual framework. Then, a set of pilot questionnaire was distributed to 50 organizations with 40 returned answers to validate the conceptual framework. This paper presented an integrated conceptual framework to manage risks in public building procurement systems in SouthEast , Nigeria. The framework covered the process in risk management in public building procurement. A set of questionnaire was distributed to organizations to validate the conceptual framework. The findings showed that avoiding the risk is the best risk management technique that has the greatest impact on cost reduction in the construction companies. The study concluded that in order to improve the chance of success and reduce these potential risks associated with building construction projects in Nigeria, risk management that is guided with the above framework should be an important part of the decisionmaking process for a construction enterprise.

It can also be defined as a (usually disastrous) overflow of water from a lake or other body of water due to excessive rainfall or other input of water (Livio, 2013). Flood is usually disastrous overflow of water from a lake or other body of water due to excessive rainfall or other input of water. Flood can also be stated as an over flowing or eruption of a great body of water over land not usually submerged. Olajuyigbe (2012) described flooding as a large amount of water covering an area that was usually dry. According to Nwafor (2000), flood is a natural hazard like draught and desertification which occurs as an extreme hydrological event. Flood can simply be said to be a flow of water above the carrying capacity of a channel Emmanuel et al (2015). The term flood according to Jha et al. (2011) encompasses a flow of water over areas which are habitually dry. Flooding which is the occurrence of a flood event is one of the most occurring natural disasters in the world today and could be said to have top the list of natural disasters that is becoming more of a threat than a constant or declining one (Schramn & Dries, 1986). Alternatively, flooding can be seen as any abnormally high stream-flow that overtops the natural or artificial bank of a stream. Simply put Flood is too much water in a wrong place; whether it be inundated city or a single street or a filled flooded due to a block drain. It covers a range of types of events, many of which can also include other sources of damage such as wind. Flooding can also occur as a result of failure of watercourses or man-made water containment systems such as dams, reservoirs and pumping systems. In 2012, Nigeria experienced its worst floods in decades. The 2012 Nigerian flood began early July 2012, killing 365 people and displaced over 2.5million people as of November, 2012. According to the National Emergency Management Agency [NEMA] (2012), 30 of Nigeria's 36 states were affected by the flood. The flood was termed the worst in 40 years. It affected an estimated total of seven million people. The estimated damages and losses caused by the flood were worth 2.6 Trillion Naira. Over 20,000 buildings affected (NEMA, 2015). In 2012, Anambra state was also hit by the devastating flood. It affected 57 communities in 8 local government areas, damaging 117,148 Farms and agro-based industries, 79 water and sanitary facilities, 325 schools, 122 health facilities and about 20,000 houses and damages totally about 30 billion naira (Emmanuel, Ojinnaka, Baywood, & Gift, 2012). In view of the effect of flood in Anambra state in 2012 in which 0ver 20,000 building, homes, schools, industries etc., were affected and what happens every year, it becomes necessary to study the type of flood in Awka which is one of the persistent places that flooding occur every year, with a view to understanding how to handle it.

The wind speed and design wind pressure for the different terrain categories adopted for this study were calculated as per logarithmic wind profile equation and BS6399-2:1997 respectively. Also, the nodal displacement of a 3D high-rise building model with reference to the calculated design wind loads were performed using finite element analysis software(STADDPROV8I). From the result obtained, it was shown that Terrain category IV when compared to other terrain categories recorded lower wind speed and pressure from the ground to a height of about 10m. The writers also observed that at greater terrain category(TC4), the wind speed and pressure tends to be much higher at the top floors(10m-48m) of the high-rise building whereas, terrain categories (TC3, TC2, TC1) recorded lower wind speed and pressure at that same height(10m-48m). this disparity however was discovered to be due to a ...

Hitherto performance evaluation of buildings has not received significant attention in Nigerian Universities. Universities procure buildings that neither respond to the demands of changing needs, nor fit for purpose. This study relies on current literature to explore how the constructs of BPE can be utilized to improve the design and management of educational buildings in the Nigerian university system. Data were generated using a convenient sample of construction professionals holding key positions in the physical planning and works departments of four Federal Universities in South East Nigeria. Data analyses were conducted using Excel and statistica; Version 9.0. The findings suggest that there appears to be an apparent lack of a systematic mechanism for measuring the success or performance of completed and occupied buildings in t...

Cognizance of prevailing acute scarcity of portable water supply, more often than not, during each year, this structural facility was also simulated for study under two distinct situations namely: when it is empty and when it is full of water. Structural analysis of the facility was carried out using the initial value model whereas the classical model served to establish validity. The study sought the stress effect arising from: empty condition and in full of water, on this facility. The investigation result revealed: Both classical and initial value models led to identical results. Effect of stress which resulted from the two different conditions did not diminish the structural integrity of this facility.

In its resolution, an interest in regenerative approaches to design and development had grown in many foreign countries, while Nigeria, has occupied herself with regeneration in the aspect of sustainable urban renewal. This research therefore, is aimed at assessing the extent to which regenerative design is practiced in Ngozika Housing Estate with a view to effectively implement the concept within the study area. The study adopted the use of survey method of research, review of related literature, and structured questionnaires to source for information. Sample size of 285 residences from a population of 1000 residences in Ngozika Housing Estate Awka, and 116 sample size from a population...

However, the dart of uncompleted and abandoned projects that littered the environment calls to mind the procurement method employed to deliver such projects. This paper seeks to appraise the contributory effects of procurement methods on abandoned projects. The population considered was developmental projects that have been developed to construction stage. This was stratified on the basis of project facility types. Primary data were obtained through structured questionnaire on procurement methods employed, factors that influence the choice of the procurement methods and the effects of selected procurement methods on project delivery. Data collected was analyzed using mean-score item, Chi-square and Spearman rank-order corre...

SBS is associated with non specific symptoms, which has attracted researchers and yet little has actually been proven about it. The aim of this study is on analysis of symptomatology of sick building syndrome in selected office buildings in Awka, Anambra State, Nigeria, The methodology involved survey research design, structured questionnaires, interviews and review of related literature. The Staff of the three office buildings A, B and C formed the population, while purposive sampling techniques was used to select one hundred and five (105) Workers Questionnaires were distributed to the 105 workers using stratified random sampling method. Ninety (90) was returned which was 86% response rate. Data was analyzed using frequencies, percentages, column charts, pie chart and Pearson correlation coefficient was employed in testing the hypothesis. Results identified the major...

Hitherto performance evaluation of buildings has not received significant attention in Nigerian Universities. Universities procure buildings that neither respond to the demands of changing needs, nor fit for purpose. This study relies on current literature to explore how the constructs of BPE can be utilized to improve the design and management of educational buildings in the Nigerian university system. Data were generated using a convenient sample of construction professionals holding key positions in the physical planning and works departments of four Federal Universities in South East Nigeria. Data analyses were conducted using Excel and statistica; Version 9.0. The findings suggest that there appears to be an apparent lack of a systematic mechanism for measuring the success or performance of completed and occupied buildings in t...

Cognizance of prevailing acute scarcity of portable water supply, more often than not, during each year, this structural facility was also simulated for study under two distinct situations namely: when it is empty and when it is full of water. Structural analysis of the facility was carried out using the initial value model whereas the classical model served to establish validity. The study sought the stress effect arising from: empty condition and in full of water, on this facility. The investigation result revealed: Both classical and initial value models led to identical results. Effect of stress which resulted from the two different conditions did not diminish the structural integrity of this facility.

Being a survey research, questionnaires containing information relating to issues and drivers on global competitiveness were administered to selected construction practitioners in Anambra State, Nigeria. Accordingly, a total of 84 questionnaires were administered out of which 80 copies were completed, returned and found useful. This corresponds to a response rate of 95%. Data collected were analyzed and presented using mean score, percentages, relative importance index (RII) and tables. The study found that the identified twelve (12) drivers of global competitiveness were all significant in the study area. However, the most perceived significant drivers for global competitiveness in the study area is labour market efficiency. Also, the study observed that the Nigerian construction industry operates at the level of factor-driven economy. Therefore, the...
