Sustainable development was partly defined as humanity’s ability to meet the needs of the present. Thus, in a bid to achieve sustainability from existing building, some public office buildings were improved (as against maintenance), however past studies showed that these interventions do not always reflect user requirement which consequently had impact on job productivity. This paper thus applied lean thinking (muda) drivers to the diagnosis of user requirement in an existing public office building in Nigeria to determine its impact on job productivity in developing countries and determine its feasibility in enhancing the assessment of end-user requirement in a typical improvement diagnosis technique. A total of 168 useable questionnaires were retrieved to conduct the quantitative study, using satisfaction index and multiple regression analyses. The paper concludes that the highly prominent muda drivers negatively affect building and workers performances, while the less prominent ones affect both performance positively, and that the application of lean could enhance improvement diagnosis technique. The paper recommends that lean should be used as a supplement rather than a replacement to a typical diagnosis technique, since it works only with inputs from the end-users who may not be able to provide the technical and professional details required for the assessment of the building elements condition, which might otherwise require the use of sophisticated equipment.

FACILITY MAINTENANCE MANAGEMENT PLAN 2: A FRAMEWORK
Sylvanus Musa Hassan
Department of Architecture, Kaduna State University, Kaduna State
Building maintenance operations ensure that facilities retain their structural, functional and aesthetic conditions throughout their lifespan, and are most effective when carried out according to well laid out plans and procedures, (Atkin & Brooks, 2005; Waziri & Vanduhe, 2013). A Facility Maintenance Management Plan (FMMP) therefore aims at increasing organizational profitability and operational efficiency by strategically outlining policies and procedures that synchronize organizational goals and objectives with appropriate maintenance operations. This research is a continuation of a previous study – on Kashim Ibrahim Library (KIL) of Ahmadu Bello University Zaria, which identified a link between poor building conditions and maintenance culture to the lack of a maintenance plan, thus recommending the use of a documented FMMP, (Musa, 2018). This research therefore aims at developing a framework for the FMMP – using literature review to establish the relevant theoretical concepts, and identify issues which will form the topical headings for the documents contents. The framework template developed in this research will hopefully provide a basis for developing a maintenance plan for KIL, and also aid industry practitioners with a clear and concise methodology for documenting a FMMP.

Baba Adamu Mohammed
Department of Geography, Yobe State University, P.M.B 1144 Damaturu, Nigeria
Desertification is one of the major threats to both ecological and agricultural productivity systems in arid and semi-arid environments, all over the world. This paper examined the impact of desertification on agricultural productivity and livelihood in Yunusari and Environs, Yobe State, Nigeria. For the purpose of this paper data were generated from both primary and secondary sources, using two-stage sampling technique. The first stage was the purposive sampling of three communities namely Yunusari, Bukarti and Kanamma. The second stage involves random sampling of 100 respondents from each of the purposively sampled three communities, totaling 300 respondents. The primary data were collected through field observations, group discussions and questionnaire administration. The study also explored relevant literatures in form of published and unpublished books, journals and e-materials as secondary sources. Analysis of data was achieved by using two suitable statistical tools namely percentage (use of tallying method and frequency tables) and Chi square analysis. The paper revealed that climatic variability and unregulated human induced activities such as deforestation, bush burning, over-grazing, poor irrigation practices and over-cultivation fueled the rate of desertification in the study area, thereby impacting on agricultural productivity and livelihood. It further revealed that farmers have been deprived of farmlands by sand dunes; inadequate water as most of the sources have shrank in volume, thereby negatively affecting agricultural productivity and income in the study area. Thus, the paper recommends environmental enlightenment program to foster result-oriented stakeholder mobilization and commitment; tree planting campaign in public places like schools; sustainable rural afforestation projects, affordable and available fuel efficient stoves and proper funding for investigative researches that are aimed at addressing desertification related developments.

This article presents assessment on the effect of partially replacing clay with Saw Dust Ash (SDA) and Tin Ore Waste (TOW) for the purpose of making bricks. The SDA was kept at constant 4% while TOW was varied at 2%, 4%, 6%, and 8% by volume of clay designated as E1, E2,E3 and E4, while the control specimen is C (100% clay). The produced specimens (cubes and prisms) were cured for 7 days using cellophane material. The bricks were fired at 4000c, 6000c, 8000c and 10000c in a furnace. After firing, properties such as compressive and flexural strengths, density and water absorption were examined. It was observed that the bricks strengths increases with an increase in Tin ore waste (TOW) .The optimum compressive and flexural strength results were found at E4 (4% SDA, 8%TOW and 88% clay) having 5.90N/mm2 and 3.15N/mm2 representing 39.50% and 27% increase when compared to control specimens with 3.57N/mm2 and 2.43N/mm2 at 10000c .The density and water absorption decreases when SDA and TOW were used. At optimum E4 (4% SDA, 8%TOW), the density and water absorption values were found to be 1676kg/m3 and 14.02% representing a decrease of 9.98% and 11.43% compared to control with density and water absorption values of 1862kg/m3 and 15.83% at 10000c firing temperature. It was concluded that incorporating sawdust ash (SDA) and tin ore waste (TOW) in clay bricks improve some engineering properties of fired clay bricks.

Environmental friendliness has been the campaign of several governments in developing, under developed and developed countries since the turn of the 21st century. It has been equally observed that while the sensitization and campaign have taken different turns and forms not much have been achieved. The environment have defied virtually all efforts at making it better or improved. This research is necessitated by the degenerating nature of human environment since the turn of the 21st century. The scholars adopted several empirical data collection techniques aimed at achieving a better human environment. The techniques included oral interviews, use of questionnaires, textbooks, journals, newspapers, periodicals and internet. A few theoretical strands were incorporated into the work to make it worthwhile. The work concluded with the scholars suggesting ways to improve our human environment in Nigeria in particular and the world in general.

The importance of transport as an essential service in Urban Centers, cannot be over – emphasized. Road transportation in particular has contributed in many ways to development. Babatunde (1998), for instance, has stated that road transport is significant in the sense of making possible the realizations of the broad development objectives of the average citizens social and economic desires. Road as an integrated system that is made up of nodes and routes. The nodes are towns which associated themselves to the roads, while the routes are the different types of roads. Roads are economic penetrating routes which are required to open ways for investment in activities like agriculture and commerce as well as elements which formed the necessary ingredients of nearly every aspect of economic and social development. It is in the light of this that this paper assesses the role of road transport network in urban development, by highlighting important factors that determine this role such as road design principles, relationship between land-use and transportation as well as strategies for making urban road transport more efficient to urban development. The research has employed desk study as method of data collection. Finally, recommendations were made towards achieving an efficient road transport network in urban areas in Nigeria

Monetization policy of the Federal Government was borne out of waste and and corruption being experienced from improper management of publicly owned property. The ownership and subsequent management of such landed property were transferred to private individuals. However, due to expedient reasons certain categories of these government properties are still being held and managed by public estate officers of which the residential quarters and main offices of National Industrial Court are included. This paper explores the problems of public property management which span from corruption, nepotism in awarding repair contracts to bureaucratic bottleneck involves in carry out some of the simple job of property management. The research adopts distribution of questionnaires to the stakeholders and use simple descriptive analysis in identifying the solutions to the problems aforementioned.

One characteristics perculair to man is that he progressively changes his environment to meet his biological and social needs. On a social organized basis man provides himself with the materials necessary for life which he removes initially as now materials from his environment. It is in the provision and utilization of these material necessities, that worthless and sometimes harmful by-products originates. This study is aim at increase awarness of the envirionemntal problems caused by the discharge of untreated or partially treated waste containing algae putrients, non-biodegradable organics, heavy metals etc; which will hasten the deterioration of receiving water bodies. The data of this study were collected through rate of flow of waste water from the various points of generation in the savannah sugar factory. The data was determined and samples analysed by measuring the following parameters; Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Suspended Solid (SS), PH and the temperature. The results obtained from the investigations showed that the conventional waste water treatment method using a combination of grit chamber and sedimentation tank for the primary unit and a low rate aerobic stabilization pond as the secondary unit were capable of reducing the carboceous BOD by more than 90% using a 9 day detention time for the pond.

Flagship projects act as a catalyst for further regeneration and development, many of which are led by a collaboration of municipality and private developers. The implementation of flagship regeneration projects involving the development of leisure and culture-based facilities and activities in urban areas has been a fast-growing type of urban intervention in post-industrial West European and North American cities right from 1980s. The idea that flagship or prestige projects can be employed as a driver for urban economic growth has become part of the newly accepted way by which cities seek to enhance their competitive position. The influence of flagship developments on socially problematic local neighbourhoods has become a more central concern of governments and other stakeholders in many Western countries over the last two decades. Flagship regeneration has had a substantial effects on improving the physical quality of public spaces by creating arenas for social interaction and educational activities. The implementation of flagship projects in developed countries and Nigeria were discussed as well as its positive and negative effects. This paper points out that the success of flagship projects in developed countries has spur the developing country like Nigeria to follow suit for urban regeneration through ppp (public private partnership arrangement).

The usual application of High Strength concrete[HSC] in many construction industry is reviewed, and HSC which is produced in the laboratory by the application of available local materials. The potential uses of the ordinary Portland cement (OPC) and Portland pozzolana cement (PPC) for the production of high strength structural concrete were observed. The rate of concrete compressive strength development and the effects of curing durations on the strength of concrete specimens were also investigated at the ages of 7, 14, and 28days after casting. The effects of close rate of chemical admixture on the compressive strength of concrete were used for the study. The observation on the test results revealed that ordinary Portland cement has higher rate of strength development and results in greater compressive strength
