The framework of a construction industry could be identified by the nature of the work, by material type, contract volume, difficulty, and position of end products. In the planning phase of the construction projects, two fundamental constraints should be taken into account, and they include; quality and cost. To ensure a successful outcome, it is crucial to evaluate both limitations in the project's schedule and implementation. The management, economics, and quality of home construction are rapidly becoming a subject of international study, practical analysis, and execution. The construction of a project involves a broad range of complex operations. While supervising a construction operation, clients' demands and budget should inform of the adequate standard fit for quality. This is because if a project is not adequately managed, construction firms will encounter a substantial economic impact. Consequently, project management is a critical means for developing construction processes and successful completion of the project. This study gave prominence to a conversation about management, economics, and quality of home building construction. This is considering that customers are generally concerned with quality and costs when engaging professionals for procurement. The quality of the project outcome depends on prescription construction details, and the cost is the quality-related financial outcome. This study explains how residential building companies can create external partnerships, obtain direct and indirect support, and deliver optimal project results. It also explains how it is necessary to monitor and manage the quality and efficiency of the project via an enhanced economy control in the home constructions.
The industry of construction is considered a strong economic factor and one of the most dangerous industries. This industry involves a wide range of activities that subject all employees from experts to non-skilled workers to intense undesired situations. Everybody is vulnerable to the hazards, risks, and dangers of this massive industry. Insufficient health and safety management, damage to construction, and constructed environments can also lead to increased accidents and injuries. Accidents not only have consequences of significant suffering and pain, but they are also marginalizing efficiency, time, productivity, negatively impact the environment and overall adding the construction costs. The results of the study will help to identify the essential factors that cause rising rates of risks in construction projects. By identifying these causes, emphasis on environmental, health and safety management will help in implementing awareness to all of those participating in the construction projects. This study demonstrates the criteria and guidelines for the identification, to determine the controlling environmental effects and health and safety hazards at construction project worksites. Furthermore, attempt to explain the techniques of decreasing hazards by the development of pre-construction planning and provide adequate controlling equipment for executing a safer, more profitable construction project from start to the end. Also, in the study suggestions are given for management that they must provide adequate health and safety training for the entire workforce, a supervised workplace by professional site safety managers and operators that will attempt to reduce health and safety hazards at sites.
When someone decides to buy a house or any other estate near the shoreline, they do not think that in future nature will impact the value of their asset significantly. Further to the risks of hurricanes or any other natural hazards (such as tsunami), waves are gradually shifting the coastlines by displacing soil from a location to various areas. In recent decades, coasts have been affected by a significant deterioration due to weather conditions, waves, and coastal soil erosion. Hence, it needs precise environmental consideration, and preserves coasts for leisure, specifying reasons that promoted effective technologies from immersed structures to coastal nourishing. Therefore, by constructing sea-walls should prevent shoreline environments, especially the mechanism of sedimentation, long-shore transfer of sand, altering the coasts to the significant proportion which results from weathering and sea waves sever. In this paper, an overview submitted to the kinds of seawalls and specifications needed to sustain the seawalls. There explained the positive and negative effects of seawalls on coastal area, and the required factors to enhance seawalls stabilization against overturning and sliding failure. Also, the developed types of seawall structures have been identified that, in addition to the more practical vertical model, the stepped, rubble-mound, and curves have also been designed. It is recommended to coastal structure designer and engineers, in the pre-construction stage should precisely be studied on the coast situation and weathering conditions in the area, that is essential to make sustainable decisions and designs for construction of these structures.
Nowadays, to analyse and determine the maximum seismic lateral displacement for reinforced concrete (RC) structures, the most applicable procedure used by structural engineers is the nonlinear static (pushover) analysis. The nonlinear static procedure (NSP) is a common approach for analysing the seismic performance of construction structures. By directing this procedure, the weak points in each structural member can be examined, and it also determines whether the members are safe or need to rehabilitate. This process defines the level of performance and shear strength under seismic diffusion to construct each element of the structure. The displacement, the base shear, the plastic hinge model, and the effect of the different plan on seismic response of structures has been reported. When concentrating on the RC structures, it requires the ability to conduct lateral resistant force systems, which one of them is commonly known as moment-resisting frames (MRFs). In this paper, three models of RC structures considered for low-, medium-, and high-rise buildings were examined, and each model has been analysed for three different spans. These models have been analysed applying ETABS software by inputting and examining a wide range of structural parameters. A comprehensive study on the pushover curve, performance curve, among others have been performed. The aim of this study is to consider the effect of plastic hinges in various ranges of performance capacities to evaluate the elastic stiffness factor of structures
