The use of geosynthetics in engineering has been a viable solution alternative more frequently in recent years due to the multiple advantages it offers. Today there is a great variety of these products, which already have regulations. In the paving field, its use is given for the conservation and reinforcement of the structure, applying the Giroud-Han methodology and being verified by means of the SpectraPave ™ software, we can obtain the ideal conditions for the pavement structure using TriAx® TX140 geogrids and TriAx® TX160. Therefore, in this article the same initial conditions will be taken to compare designs and costs of these products. In this way, it seeks to inform about the facilities of designing through software, how practical it can be for people dedicated to this area to search for the most suitable geosynthetic and to promote this type of programs so they will have a greater reach.

The construction industry remains one of the few most labor-intensive industries in developing countries. Therefore, it is very important to understand the concept of labor productivity and Equipment Productivity in construction. In different researches, it was argued that construction productivity measurement techniques could be perceived as theoretical, difficult and expensive for construction companies to adopt This research is performed to identify the factors affecting Equipment productivity and Labour Productivity in building construction projects. The questionnaire is designed based on the research method to be used after the thorough investigation of the literature and identification of various factors affecting labor productivity in building construction. Total Twenty factors are divided into main five groups for Equipment Productivity and a Total of forty-one factors are divided into main nine groups. Data Analysis through M.S excel has been carried out. Also, all factors affecting Labour Productivity and Equipment Productivity have been ranked using the RII method, FI method, and the SI method. Analysis has been carried out for each stakeholder group and also as an overall response from stakeholders. Spearman’s rank correlation coefficient for each possible combination has been carried out using the ranks between city, methods, and stakeholders, which showed that there is agreement among respondents regarding ranking the factors affecting labor productivity in construction sectors.

The U.N has launched 17 Sustainable Development Goals (SDGs) in 2015. It was adopted by 193 member states; the goals represent a vital international step in setting humanity on a trajectory towards sustainable development. We will also get an overview of how sustainability has been understood, as well as an introduction to the SDGs – what are they, how progress can be determined and measured, and how the SDGs are relevant for the system management of the world. We will also examine how various societal actors are responding to and implementing the SDGs. The process moves towards proper implementation; there is a need to focus the scope and disciplined nature of the 2030 Agenda and the importance of the challenges. It requires science-based analysis and many tools to realize the ambition. This report investigate the nature of interlinkages in between the SDG. It is based on a science-based and informed analysis of interactions across SDG domains that can support more coherent and effective decision- making, and better facilitate follow-up and monitoring of progress. Understanding possible trade-offs, and the relations between the different SDG, is crucial for achieving long-term sustainable development outcomes. Although all of the SDGs are essential to sustainable development, SDG 13, Climate Action, is usually the urgent one in terms of the need for a swift implementation on a global scale. Therefore, a particular focus is given to this SDG. The role of agriculture in destabilizing the Earth system at the planetary scale, by examining nine planetary boundaries, or “safe limits”: land-system change, freshwater use, biogeochemical flows, climate change, biosphere integrity, ocean acidification, stratospheric ozone depletion, atmospheric aerosol loading, etc. It will gain up-to-date knowledge of the current understanding of human impacts on the Earth at the planetary level. Kate Economics Green Model for the 21st century is also looked upon. Also, the data of interviews by experts are included, which provide insight relevant to the topic at hand.

Monitoring of a structure after its construction is as crucial as it is during its designing or construction. Properly monitored structure could avoid a lot of catastrophic accidents. Structural Health Monitoring (SHM) plays a vital role. Earlier analysis of the systems by professional experts was performed visually. Various Non-Destructive Tests (NDT) like Rebound Hammer, Ultrasonic Pulse Velocity Test, etc. are utilized for the inspection. Along with these piezoelectric transducers have proven to be another way if evaluation of the structures.Electromechanical Impedance (EMI) technique by means of piezoelectric materials has been widely carried out for the structural response at various stages. EMI has the potential to detect damages, corrosion and even the strength of any structural member. This review paper includes the various studies that evolved from the past decade related to EMI dealing with new concepts and ideas.
