Abstract: The work verifies the morphological variation of strength in various sizes of solid timber beam in order to ascertain their respective volumetric strength mode at the three (3) perpendicular directions. In this work, a mathematical tool known as Volume Integral was adopted to analyze the volumetric strength mode of timber in mutually perpendicular axes of three (3) batches (A, B & C) having five (5) different sizes of solid timber beam respectively and thereafter, morphological values generated were used in determination of ultimate bending strength assuming Ekki lophira alata, as the timber specie. The result of the analysis showed that increase in timber morphology increases the volumetric strength mode. Also that the maximum volumetric strength for all the sizes of the solid timber beam analyzed occurred at the tangential axis which is perpendicular to the grain direction and tangent to the growth ring (x-direction) followed by the volumetric strength of the radial axis which is als

Abstract: Reinforced concrete construction entails substantial support work and formwork activities, which expose workers to, inter alia, work at elevated heights, ergonomic hazards, and hazardous chemical substances. Furthermore, support work and formwork are required to support and or restrain substantial loads and forces, is dependent upon a range of resources, and is influenced and contributed to by a range of stakeholders. Consequently, the integration of design and construction, scientific designs, the implementation of documented Quality Management Systems and H&S programmes, and optimum appropriate education and training are essential. Certain categories of problems relative to support work and formwork such as damaged components, inadequate design, and inadequate erection are experienced more frequently than others; GCs adopt an informal approach to support work and formwork; in general, recommended support work and formwork interventions can be deemed to be taken between rarely to ofte
