We are interested in a contact problem for a thin fixed beam with an internal point obstacle with possible rotation and shift depending on a given swivel and sliding friction. This problem belongs to the most basic practical problems in, for instance, the contact mechanics in the sustainable building construction design. The analysis and the practical solution plays a crucial role in the process and cannot be ignored. In this paper, we consider the classical Euler–Bernoulli beam model, which we formulate, analyze, and numerically solve. The objective function of the corresponding optimization problem for finding the coefficients in the finite element basis combines a quadratic function and an additional non-differentiable part with absolute values representing the influence of considered friction. We present two basic algorithms for the solution: the regularized primal solution, where the non-differentiable part is approximated, and the dual formulation. We discuss the disadvantages of the methods on the solution of the academic benchmarks.

Critical Elements

This research work is an introduction to sustainable construction. A few significant indicators and many related subsets, which are crucial to green sustainable construction and also to green buildings, are mentioned in this study. An ecocity is one that utilizes all the critical elements of the environment. Urban sustainable construction is a vital criterion in this context. Sustainable construction paves the way for the building industry to progress towards achieving realistic standards of performance, particularly in view of economic, environmental, and social concerns. Sustainability is a popular expression that has given rise to various activities throughout the world once people began to grasp the implications of sustainable construction. Sustainability, which is an important factor in reducing the negative environmental effects of construction, includes improving the control and efficiency in the use of raw materials, land and power consumption. The lifetime of a building is based on some factors that are prognostic regarding the manufacture, remodelling, support, utilization, and administration of the building, and finally, the sources of utilization and waste formation, annihilation and devastation. All of these give rise to a range of ecological issues in the life of a building. Generally, a sustainable building and construction involves a reduction in the utilization of energy and also wastage from the beginning of the construction process and throughout the lifecycle of the building. Moreover, the environment is faced with mounting devastation due to the exploitation of natural resources for building construction and the replacement of agronomic regions by residential areas.

Sustainable Environment

The extraction of building materials from their resources through harvesting, preservation, and utilization has become a significant segment of human contribution to the global ecosystem since the industrial revolution. Bamboo is the world's fastest-growing woody plant, and bamboo grows multiple times quicker than most species. Housing is one of the focused demands for bamboo, and as a result of the current scarcity of home units, the demand for bamboo is increasing. Bamboo building construction is portrayed by a basic edge approach like that applied in traditional building design and construction. Applying bamboo as an environmentally friendly material is seen as a movement towards creating a sustainable environment and reducing greenhouse emissions. The need to employ government policy in addressing the production and application of bamboo is reported, and the challenges of bamboo in the global market are highlighted in this chapter.

The forest product industry in Nigeria is barely surviving rather than thriving. Faced with a lot of challenges, the industry has witnessed the closure of many wood processing industries while a few are operating at low capacity. This paper examines engineered wood products and the outlook on wood and wood products in Nigeria. It discusses some of the challenges that have inhibited the growth of the industry and provides recommendations for reinventing the industry through development of modern value-added wood products for sustainable building construction.

Parametric Cost Estimation

An overall scoping review was conducted to examine research on building construction costs in the past decades. The aim is to provide a better understanding of conventional building construction cost estimation methods, gaps and potential improvement strategies that may mitigate the high risk of the cost overrun in conventional and sustainable building. This study first examined the components included in a building's construction cost and the commonly used calculation methods for cost estimation. Then, additional components included for sustainable buildings were identified and explained. The causal factors for construction cost overruns in sustainable building werediscussed as well. The findings concluded the following: (a) there is no consistent cost definition used in the industry; (b) a variety of cost estimation methods create ambiguity and confusion; and (c) newer cost estimating methods and tools, such as parametric cost estimation, which integrate risk and uncertainties have not been broadly adopted by the building industry. The current practice used to determine a sustainable building's cost estimation is the same traditional method that has been used over several decades, which is based on the material and labor costs. Such a conventional approach does not consider other factors, including the complexity of the sustainable building system, an organization's environment, and the capability of teams, among others. To respond to such a knowledge gap, a comprehensive and consistent cost estimation framework was proposed to integrate risk and uncertainty consideration, which is particularly prevalent in sustainable building.
