There appears to be a coordinated effort the world over to achieve digital switch over (DSO) from analogue based to digital technology. Ghana signed the Geneva agreement which set 17th June 2015 as the deadline for the DSO. This switch over will create new spectrum opportunities for many wireless technologies due to the abundance of radio spectrum the switch over provides. This paper focuses on the opportunity for using White Spaces (TV frequencies allocated to a broadcasting service but not ...
Abstract This paper presents the results of investigation conducted to evaluate the properties of concrete containing aluminum Roofing Sheet Waste as partial replacement of cement by weight. The properties investigated included the setting times of cement-ARSW paste, workability, density, compressive strength using 168 numbers of 150 x 150 x 150 mm cube specimens. The chemical compositions and pozzolanic properties were also investigated. The results showed that: (I.) the chemical composition...
ABSTRACT The study focused on maintenance management practice in public and private properties, (a case study of selected public and private housing estates) in Lagos state, Nigeria. To achieve this, case study of 10 selected housing estates were carried out by means of structured questionnaires. A total number of 200 questionnaires were administered to the selected estates and 141 were returned and used for the analysis, and this gave a response rate of 70.5%. Th...
Abstract The research was conducted on investigation into papercrete brick, as an alternative to paper waste management in Abubakar Tafawa Balewa University Bauchi. The demand of paper consumption represents a permanent issue in day to day activities which if a holistic approach is not taken to manage it waste effect, there won't be any sustainability achievement. A laboratory approach was employed ranging from soaking, mixing, casting and curing, finally physical and mechanical propertie...
ABSTRACT In recent years there has been an increase in the number of construction works and concrete is the main construction material for most of the structures that are being built. Nigeria is a developing Country with a large population and land area therefore a consumer of concrete. This paper considers the option of recycling concrete in order to meet the high concrete demand and effective management of construction and demolition waste. The test focused on the use of recycle...

Abstract This research is all about design, construction and preparation of cost estimate for a reinforced concrete winder stair. This type of stair is one of most important stair, use where there is no enough space. Winder stair is very common in older homes, often used as a secondary staircase where the grand staircase may have been in the entry and the winder used as an access to the kitchen, it has more visual interest. Winder stairs meander around corners. For this reason, it has gained ...
Construction industry in Nigeria had been a major source of employment for 70% of labour in the country, thus it controls the capital flow, as well as labour resources, which has cost implications. Adequate management of these resources is considered an important aspect of project works; so also if the resources are adequately harnessed, issues that pertain to cost overrun would not arise which could result to variations and claims. The growing need for construction of all types coupled with ...
The study emphasised on the maintenance manual and inspection of buildings. The paper reviewed the existing literature on building maintenance, and inspection of building, types of maintenance, causes of maintenance, inspection types and procedure, stages of maintenance, and factors influencing the decision to carry out maintenance work. The study utilized a structured questionnaire which was administered on the maintenance management industry and house owners in the study area. The analysis ...
This study is on an Appraisal of application of building facility maintenance of public buildings in Federal poly Oko. Some of the objectives include; determining the nature and types of public building, to examine the current condition and state of maintenance of public buildings, to identify the underlying factors that militated to poor maintenance of public buildings and make suggestions and recommendations towards the adoption of effective maintenance policy. A researc...

Abstract Investigations are ongoing for continuous improvement in the properties of stabilized earth for low cost housing. This research examined the influence of palm fibre on the characteristics of cement stabilized laterite interlocking bricks. Specific objective is to examine engineering properties of cement stabilized laterite with palm fibre additives and to compare the cost per square meter with conventional sandcrete blocks. Seventy-two (72) bricks were produced comprising six dif...
ABSTRACT This study investigates the effect of curing methods on the compressive strength of concrete with fine and coarse aggregates components fully and partly replaced with lateritic sand and periwinkle shell respectively. A total of 90 cube specimens of 100 x 100 mm dimensions for each percentage replacements ranging from 10 to 40% percentage replacement of fine aggregate with lateritic sand and coarse aggregate with periwinkle shell and 100% percentage replacement of fine aggregate w...
ABSTRACT The quest for the government to provide more affordable housing for the masses has necessitated more researchers to continue to investigate alternative means of low cost Building materials. Earth made bricks have been recognized as one of the oldest building material. It is not enough to provide these low cost houses but more efforts should be geared towards durability and other mechanical properties. This research examines performance characteristic of earth made brick to determ...
Abstract This research tends to compare the workability and compressive strength of granite against periwinkle and palm kernel shells as coarse aggregates in concrete production. Specific objective is to determine the workability of local substitute for granite using periwinkle and palm kernel shell as coarse aggregate, and to compare the compressive strengths of periwinkle and palm kernel shells with granite based concrete using different concrete mixes. The One-hundred and eight cubes p...
