Abstract
Provision of affordable Housing is a basic human need, and in a developing economy such as Nigeria, the government is continuously seeking innovative means of tackling the challenge of housing deficit. The growing population coupled with the lack of adequate housing has necessitated the need for a strategy by architects and designers to proffer solutions that will complement government housing policies. This study aims to propose adaptable design strategies in the provision of affordable mass housing in a developing economy like Nigeria. To achieve that, the following objectives were pursued: to propose strategies for land-use efficiency, to recommend guidelines for flexibility in design and to incorporate end users’ opinion in the design of mass housing schemes. The study adopted the qualitative research method through the review of existing case studies. Among the recommendations made was proposing guidelines on adaptable design that will aid architects and designers in the design of affordable mass housing schemes.

Abstract
There’s been a significant increase in Natural disasters in the world today, which is as a result of global warming/climate change. Besides other contributors, buildings are high contributors to this, studies have shown that they are the largest energy consumers and greenhouse gases emitters in both developed and developing countries. This study is aimed at determining the extent to which the CO2 emission of a typical modern building can be reduced so as to help combat global warming/climate change, through reviewing related literature/data gotten from other researchers. Building embodied energy was critically analyzed, and it was observed that it can be more or less depending on the initial embodied energy of the building. The building materials embodied energy, which constitutes the initial indirect embodied energy of the building, can be significantly reduced by the use of environmentally friendly building materials which will in turn reduce the building initial embodied energy and eventually, the building embodied energy. This study tends to recommend that the commonly used ordinary Portland cement with high embodied energy should be totally replaced with fly Ash, as well as the replacement of the hollow concrete block with Autoclave Aerated Concrete (AAC) blocks which is a derivative of Fly-Ash. It also recommends the introduction of green vegetation within and around the building envelop, to help minimize the CO2 emitted by the buildings as much as possible, in the course of running and maintaining them.

Abstract
The measure of construction activity affects the general wellbeing of the construction industry. An improved method of construction delivery reduces the problems encountered in the construction process. Studies posit that the use of Information and communication technologies (ICT) tends to improve construction output. However, there are barriers to ICT applications in the construction industry. To date several, the literature on challenges to ICT has been limited to a specific study area. This study conducted a narrative literature review to identify the challenges to ICT application in the construction industry across Europe, Australia, North-America, Africa, and Asia. The review was conducted using selected relevant academic journals from SCOPUS database. The findings from the review identified that challenges to ICT application are classified into Technology, Process and People related factors. The attitude of staff and Management to ICT, technical barriers and cost related factors are identified as the common factors to the three classified categories of challenges to ICT used in the construction industry. The implication of the findings is to address a platform for better and innovative construction process. It is also important in addressing people, process and technology which are interwoven for construction work.

Abstract
Embracing the principles of green building in development is crucial in creating a sustainable environment. However, research on its adoption in educational institutions is very low and students’ opinions are not given priority in the few research that are available in Nigeria. This study therefore investigated the perception of built environment students on the need to embrace the principles of green building in Covenant University, Ota, Ogun State, Nigeria. 101 questionnaires were administered to students in the Departments of Architecture, Building Technology and Estate Management of the university and a response rate of 94% was achieved. The data collected was analysed using descriptive statistics such as percentage, weighted mean and relative importance index (RII) and the data was presented in tables. The study revealed that 88.42% of the students are aware of the concept of green building. According to the students, the degree of embracing green building standards in Covenant University is very low. Moreover, the benefits the students perceive the university can derive from adopting green building principles are: improved indoor air and water quality, reduction in pollution and environmental degradation, energy efficiency and water conservation. In addition, the students identified the following as the main barriers to green building adoption: ignorance on green building principles and their benefits (RII = 0.91), high cost of green building technology (RII = 0.89), ignorance on professional knowledge and expertise on green building (RII = 0.89), ignorance on green building principles promotion by government (RII = 0.87) and ignorance on importance attached to green building principles by management of universities (RII = 0.87). The study recommended, amongst others, that there should be a forum where university management teams can be enlightened on the gains of embracing green building standards. This study is expected to broaden the knowledge of the Management of Covenant University on the importance of green development which will make the university environment to be conducive for learning, which will in turn aid better students’ academic performance. The study concluded that green building principles are vital to the physical and aesthetic planning of any development as it will reduce the amount of raw materials used in construction.

Abstract
This study examines the perception of accessibility provisions in selected art centres in Lagos, Nigeria. The research investigated how architecture influences the people and their development, enabling or hindering them across many facets which influences economic growth. The concept of accessibility significantly affects a society’s interaction with its architecture and infrastructure. With a focus on accessibility, this study investigated the perception of users towards accessibility provisions in selected art centres alongside with how these provisions affect usability of these centres. A quantitative methodology of research was carried out via the distribution of questionnaires to workers and users of three selected art centres in Lagos state, Nigeria. Data collected was analysed using SPSS 21 and interpreted accordingly. The findings suggested that not all necessary access provisions are available and of the available ones, very few were effective. Inadequate accessibility leads to less utilisation of these facilities, which is having a negative effect on the users of the investigated facilities. The study concludes that in order to promote poverty alleviation, and the creation and sale of art, accessibility provisions need to be present and appropriate for all users to access the necessary facilities. It was recommended that, fully functional art centres are attainable by integrating accessibility from the onset of design.

Abstract
Utilization of clay brick wastes for production of high strength eco-concrete enables the combat of raw resources depletion due to excessive mining as well as mitigating environmental pollution caused by demolition of old brick structures in an effort to achieve environmental sustainability in line with the sustainable development goals (SDGs). This study investigates the beneficial usage of crushed clay brick as partial replacement for natural sand in producing high strength eco-friendly concrete. The replacement percentages of the crushed clay brick in respect to sand are 0, 10, 20, 30, 40 and 50% by weight using a mix proportion ratio of 1:1:2 at a constant water-cement ratio of 0.25, aiming at the 28 days compressive strength of about 40 MPa. The chemical characterization of the crushed clay brick and cement was conducted via X-ray fluorescence (XRF). The mechanical properties tests were performed on about 80 specimens using 100 x 100 x 100 mm for cubes, 100 x 100 x 500 mm for beams and 100 x 200 mm diameter for cylinders after 7, 14 and 28 days of curing in water. Results showed that concrete containing crushed clay brick as partial replacement for sand compare favourably well with the control. Consequently, it is suggested that generated clay brick wastes can be crushed and used as replacement for natural sand for the production of eco-friendly high strength concrete.

Published: November 2019

Abstract
Study of nonlinear dynamic behaviour of plates resting on two parameters foundation under various environmental conditions has been an area of increasing research interests in industrial and engineering applications. In this work, the dynamic behaviour of functionally graded plates resting on Winkler and Pasternak foundation is investigated. The inherent singularities in the governing equation are analyzed using differential transform method. Good relationship is established when the results of the semi - approximate analytical methods are compared with the already established research based on experimental. To assess the effect of nonlinear Pasternak foundation introduced, the governing differential equation is converted using Galerkin one-parameter approach into Duffing equation. Thereafter, the domain issue peculiar to semi analytical solutions is treated using cosine after treatment method. Analytical Solutions obtained are used to examine the material properties variation, linear Winkler, nonlinear Winkler and Pasternak foundation effects on plate vibration. It is established that natural frequency decrease with decrease in thickness of the plate, Natural frequency increases with increase in the value of Winkler and Pasternak foundation coefficients. The modal shape obtained satisfy the classical theory of the plate vibration. It is expected that the findings of this work will be relevant in tackling problems related to plate vibration in the industries.
Conceptual Issues in Outdoor Advertising Billboard Valuation – Lessons for Nigeria
Authors: Oni A S , Oloyede S A , Durodola D O , Oluwunmi A O 
Published: November 2019

Abstract
This paper examined, by literature, four principal conceptual issues that are germane to outdoor advertising billboard valuation namely; the concept of outdoor advertising billboard itself, the tripartite components of the billboard property, billboard legal status controversy and the money trail concept. A review of these conceptual issues was critically carried out, pinpointing their implications to valuation of billboards for many purposes such as compensation so as to enhance understanding of estate surveyors and valuers, especially in Nigeria. Findings from the literature are that; modern billboards are diverse in nature (material, displays and technology), there is no consensus yet about whether billboard is real or personal property and that the task of allocating income to the different assets that contribute to the total business value of an outdoor advertising business is herculean. While valuers should improve their understanding of the criteria that qualify an asset as real or personal property and treat each billboard to be valued on its own merit, educational and training institution in Nigeria should encourage capacity building in outdoor advertising billboard valuation.

Coordinated control of active and reactive capacity generation in electrical power distribution networks of railways
Authors: Tretyakov E A 
Published: November 2019

Abstract
This article presents an agent-based model algorithm for voltage coordinated control using reactive capacity sources in electrical power distribution networks of railways. Voltage control in an electrical network is coordinately implemented by the managing system between all local regulators within the controlled zone. We present an approach to coordinate the work of local regulators basing on auction-type ranking of their possibilities for achievement the global control purpose. During operational voltage control in electrical network we proposed to use linearization of the control task, since the relationship between relative power gains and loads of individual nodes in the form of sensitivity matrix (Jacobi) is almost linear. We performed simulation and mathematical modeling of the proposed algorithm in the distribution electrical network of railways and present the obtained results.
