The construction industry (CI) has a significant impact on the environment and on climate change due to the emission of greenhouse gases like carbon dioxide. Globally accepted Sustainable Development Goals (SDG), specifically SDG 7 (Access to Affordable, Reliable, Sustainable and Modern Energy for All), SDG 9 (Industry, Innovation and Infrastructure), and SDG 11 (Sustainable Cities and Communities) stress the responsible utilization of energy in various industries, including construction. The CI uses almost half of the world’s produced energy. Therefore, this research presents insights into the efficient use of energy in the building sector and shows how energy efficiency can be achieved by altering different parameters and components like orientation, materials, glazing, and HVAC systems through a case study of a hospital building in Green Building Studio (GBS). This paper also aims to use the Building Information Modelling (BIM) approach to make environmentally sustainable decisions to reduce energy waste in projects. Initially, beneficial factors of BIM on green buildings were identified in the literature and later ranked, based on expert opinions collected using a set of questionnaires. Average Index was used for data analysis. The identified benefits were validated by conducting energy analyses on a hospital model through 3D BIM. It was concluded that a substantial share of energy cost, carbon dioxide (CO₂), and electricity can be saved using this approach. It was determined that a quick and sustainable design process, improved energy efficiency, enhanced building performance, and provision of better design alternatives are the key benefits of the adoption of BIM by such projects. A Cronbach’s alpha value of 0.822 was obtained, which further validates the results. The proposed approach may lead future structures to be sustainable and enriches the culture of energy-efficient green buildings.

Rivalry competitiveness, significant capital investments, and cultural diversity are defining the construction industry’s evolving nature. Therefore, construction organizations have to manage their construction projects’ relationships carefully. Construction management researchers have progressively recognized the intelligible link between Relationship Management and construction project performance. However, few studies structurally reviewed the precipitated progression in this topic. This paper follows a systematic approach to review the literature from reliable databases and prominent journals between 2000–2020 in topics associated with Relationship Management in construction projects. This investigation sets to identify the key characteristics, categorial dimensions, attributes, or enablers of relationship management in construction. More than 500 articles were explored in this systematic review by thorough keyword research, out of which 73 articles were found relevant to this topic where an explicit content analysis was carried out. The findings identified 18 key Relationship Management characteristics classified into four categories: Contract-related, Management-related, Team-related, and General characteristics. Project Managers are recommended to pay specific attention on investigated characteristics to strengthen relationships, promote collaboration, and thereby foster project performance.

Solid waste is a great threat not only to the economy of any country but for the environment too. The public through various sources generate tons of solid waste regularly. In the era of globalization, one of the rising issues of developing and under developed countries is handling such huge masses of solid waste. Hyderabad is the 2nd largest city of Sindh and 6th in Pakistan. Unfortunately, it does not poses proper solid waste management system right from collection up to its proper disposal. Most of those uncollected wastage poses a highrisk to the public through blockage of drains and formation of stagnant ponds which provide a breeding ground for flies and mosquitoes with a high risk of diseases. The public role and awareness can reduce this enormous load from Government. This research aims to uncover the reasons for solid waste generation in Hyderabad city. For data collection, various dumping sites in the city have been visited. Interviews were conducted with municipal officers of city for more precise data and possible causes of waste generation. Finally, a questionnaire survey has been conducted to list out top most significant causes of poor work management in the city. The data was analyzed in SPSS 24.0 with the help of average index technique. From the analysis of data, the top critical causes have been identified for Hyderabad city and discussed with the field expert for their possible solution.
