Construction Technologies and Architecture Vol. 13

Abstract: Computer vision and building information modeling (BIM) have gained significant attention in various fields, including construction, architecture, and infrastructure management. This study presents a novel method for automatically generating 3D models and estimating quantities of construction materials from 2D scanned floor plans using computer vision techniques. The proposed Python-based program integrates complex steps, such as image processing, line and room detection, wall recognition, and 3D model generation using Blender. Additionally, the program accurately calculates the areas of different elements in the floor plan and provides detailed cost estimations for materials like cement, steel, bricks, and tiles for various masonry construction. The results of the program are encouraging, showcasing its potential to be a valuable tool in the future for digital 3D modeling and estimation in construction projects. The program aims to minimize human effort and automate processes, making it user-friendly and efficient for architects, contractors, and clients alike. However, some limitations exist, such as resolution restrictions and sub-structure estimations, which can be addressed in future enhancements.

Abstract: Sustainable development entails the responsible utilization of resources while safeguarding the needs of future generations. Central to the concept is the creation of sustainable urban systems within cities, spanning energy, water, waste management, food production, green spaces, parks, and transportation. These sustainable city elements are rooted in environmental and social considerations, striving to balance economic growth with environmental preservation. This paper delves into the intricate web of challenges confronting sustainable development in Pakistan. It draws from a comprehensive review of relevant literature and primary data collected from policymakers, experts, and stakeholders. The research uncovers a myriad of obstacles, including poverty, illiteracy, inequality, inadequate infrastructure, and political instability, hindering the achievement of Sustainable Development Goals (SDGs). Additionally, climate change impacts, water scarcity due to population growth, natural resource depletion, and environmental degradation pose significant threats. To surmount these challenges, this study advocates for targeted governmental policies, emphasizing economic diversification and increased public investment in critical infrastructure to foster social inclusion and elevate living standards for all strata of society. An integrated approach to resource management, alongside community capacity-building initiatives, especially in the context of climate change mitigation, is also essential).

Abstract: This paper explores the existing condition of the energy supply through power grids, photovoltaic (PV) system commonly known as Solar Powered system, generators etc. to 81 healthcare facilities in Sindh that were identified during rapid assessment. As the Country is facing load shedding challenges, these healthcare facilities, apart from few, are not immune from it. This makes alternate sources of energy one of the most needed elements for a healthcare facility. In response to the findings, the paper underlines the importance of efficient utilization of existing PV system setup which is available in almost all healthcare facilities however underutilized due to various factors. This study helped in finding true potential of the PV system utilization. Ultimately, this research highlights the importance of environmental aspect from energy perspective in healthcare facility and present the effective utilization of already installed solar energy to make it viable solution in healthcare infrastructure which align with the principles of the UN's Sustainable Development Goals.
