Abstract: Despite the efforts of the Nigerian government at the federal, state and municipal levels to improve road networks, the country continues to suffer from bad roads due to frequent failures. The Value Engineering (VE) technique was used in this study to analyze the construction activities and management of three projects in Abuja, Nigeria. The project began with data collecting and ended with a predicting value engineering model for cost reduction while increasing road performance. All of the factors that contribute to cost overruns in road construction projects were considered in the study. The case study was conducted in Abuja, the Federal Capital Territory, with clients, consultants....

Abstract: This study investigated the effect of dampness in terms of condensation, rain penetration and capillary rising dampness on buildings constructed in Akure south local government. A total number of 129 buildings were thoroughly investigated through the use of structured questionnaire, observation and literature review. After the investigation and assessment, it was discovered that most of this buildings experienced dampness due to non- use of damp proof membrane and damp proof course during the construction of the buildings. Also, most of these buildings were constructed in water-logged area and were not constructed by professionals. The results of this observation and structured questionnaire showed that dampness occurred in the buildings due to the following factors: Pipe leakages, water-logged area of site, non-use of D.P.M and D.P.C.poor drainage, use of poor quality of concrete (permeable concrete), holes in roof, defective construction e.g. joints, rain penetration, poor foundation, design errors in building, condensation in bathroom area of buildings, poor communication or coordination by owner with other parties involved in the construction of the buildings, poor house maintenance and construction moisture.......

Abstract: The use of the supply chain method is believed to be one solution, so that it will bring benefits to both users and construction service providers. This study aims to analyze the supply chain of boulder stone material starting from the process of selecting a provider of coastal safety wall construction work on the coast of Matani Village, analyzing the criteria and sources of risk for coastal safety walls. And get the identity of the boulder stone supplier (Quarry). Structured interviews with the Selection Working Group (Pokja Kemerdekaan), Commitment Making Officials (PPK), as well as service providers and boulder stone suppliers to obtain a series of information that will be used in decision-making analysis. Observations in the field of work and supplier quarry to determine the optimal distance required. Literature review regarding the selection of government goods/services providers in accordance with Presidential Decree no. 16 of 2018....

Abstract: Sam Ratulangi is an international airport located in the city of Manado, North Sulawesi Province. The airport which is managed by PT. Angkasa Pura I is capable of receiving loads from Boeing 737 series aircraft and Air Bus A320 Series. Periodic maintenance is carried out to maintain the capability of the existing runway. One of the maintenance currently being carried out is the project "Overlay Runway 18-36 at Sam Ratulangi Airport – Manado". This study was conducted with the aim of identifying risk factors in the project "Overlay Runway 18-36 at Manado's Sam Ratulangi Airport" related to aviation accidents and to find out the dominant risk conditions that arise in the work method "Overlay Runway 18-36 at Sam Airport.

Abstract: The use of natural resources in concrete mix assured that they are environmental friendly and cost effectively and increasing material and structure durability. Even though, there are no plenty of structures were built using natural resources in concrete, but studies are in progress and different and there is a need for further studies and experimental works. This paper aims to use basalt aggregate to produce dense, high strength, and durable concrete compared to crushed limestone aggregate and rounded valley aggregate concrete. Results showed that the use of basalt aggregate improves concrete properties. An improvement in density is noticed to be about 5-8.7% more for all grades of concrete. The improvement in compressive strength of 15-40% more for different grades of concrete using basalt.......

Abstract: This study presents a new model used in the stability analysis of a three-dimensional thick rectangular plate that is clamped at the first and second edge, free at the third edge and the other edge simply supported (CCFS) using an exact solution approach. An expression of potential energy of thick plate was formulated using 3D elastic principles thereafter, a compatibility equation of 3D plate was derived through energy equation transformation to get the relations between the rotations and deflection. The solution of compatibility equations yields the exact plates shape function which is derived in terms of trigonometric and polynomial displacement and rotations. Similarly, by minimizing the energy equation with respect to the deflection, the direct governing equation was formulated. The solution of governing equation yields the deflection coefficient of the plate......
