Redox Properties of [Cp*Rh] Complexes Supported by Mono-substituted 2,2′-Bipyridyl Ligands
Authors: Stiel Jonah , Henke Wade , Moore William , Blakemore James
Published: October 2023

The redox properties of half-sandwich rhodium complexes supported by 2,2′-bipyridyl (bpy) ligands can be readily tuned by selection of an appropriately substituted derivative of bpy, but the influences of single substituents on the properties of such complexes are not well documented, as disubstituted bpy variants are much more common. Here, the synthesis, characterization, and redox properties of two new [Cp*Rh] complexes (where Cp* is η5-pentamethylcyclopentadienyl) supported by the uncommon mono-substituted ligands 4-chloro-2,2′-bipyridyl (mcbpy) and 4-nitro-2,2′-bipyridyl (mnbpy) are reported. Single-crystal X-ray diffraction studies and related spectroscopic experiments confirm installation of the single substituents (–Cl and –NO2, respectively) on the bipyridyl ligands; the precursor monosubstituted ligands were prepared via a divergent route from unsubstituted bpy. Electrochemical studies reveal that each of the complexes undergoes an initial net-two-electron reduction at potentials more positive than that associated with the parent unsubstituted complex of bpy, and that the complex supported by mnbpy can undergo a third, chemically reversible reduction at –1.62 V vs. ferrocenium/ferrocene. This redox behavior is consistent with inductive influences from the substituent groups on the supporting ligands, although the nitro group uniquely enables addition of a third electron. Spectrochemical studies carried out with UV-visible detection confirm the redox stoichiometry accessible to these platforms, highlighting the rich redox chemistry and tunable behavior of [Cp*Rh] complexes supported by bpy-type ligands.

Published: October 2023

Despite the rapid expansion of the organic cathode materials field, there is still a lack of materials obtained through facile synthesis that have stable cycling and high energy density. Herein, we report a two-step synthesis of small organic molecule from commercially available precursors that can be used as a cathode material. Oxidized tetraquinoxalinecatechol (OTQC) was derived from tetraquinoxalinecatechol (TQC) by the introduction of additional quinone redox active centers into the structure. The modification increased the voltage and capacity of the material. The OTQC delivers a high specific capacity of 327 mAhg-1 with an average voltage of 2.63 V vs. Li/Li+ in the Li-ion battery. That corresponds to an energy density of 860 Whkg-1 on the material level. Furthermore, the material demonstrated excellent cycling stability, having a capacity retention of 82 % after 400 cycles. Similarly, the OTQC demonstrates increased average voltage and specific capacity in comparison with TQC in Zn-organic battery using aqueous electrolyte, reaching the specific capacity of 326 mAhg-1 with an average voltage of 0.86 V vs. Zn/Zn2+. Apart from good electrochemical performance, this work provides an additional in-depth analysis of the redox mechanism and degradation mechanism related to capacity fading.

Mosaïque de Dionysos découverte à Hiérapolis (Manbij) en Syrie du Nord
Authors: ABDALLAH Komait , AL-KAIED Mouhamad
Published: October 2023

In 2017, the remains of the two mosaics were accidentally found in the city of Manbij, 60 km northeast of Aleppo in northern Syria. These mosaics seem to be part of the same architectural context that has completely disappeared. The best preserved mosaic has a very interesting theme. It is the Dionysus scene with his thiasos including Satyr and Bacchant and leopard. There is also an other scene of landscape with river god and animals. The last one, so damaged, conserve just a mask and the rest of two personages and an amphora, beside it, there is an inscription mentioning Eros. The scene of Dionysus evokes the well-known figures in Zeugma and Antioch, Turkey, dated to the end of the 2nd century AD and the beginning of 3nd centuries. Perhaps, it represents the epiphany of the god. The others scenes are probably linked with Dionysus iconography. The mosaic could be dated, according to the stylistic criteria, to the end of 2nd century AD and the beginning of 3nd century AD. It attests the diffusion of the Dionysus cult in the city of Manbij (Hierapolis) in the roman period.

Ayrıca öğrenim durum düzeyleri yüksek bireylerin güç paylaşımı boyutunu öğrenim düzeyi düşük velilere göre olumsuz değerlendirdikleri ve gelir durumu yüksek velilerin güç paylaşımı boyutundaki okul aile iş birliği düzeylerinin azaldığı söylenebilir.
ARISTOTELES’TE PRATİK AKIL YÜRÜTME: LOGISMOS
Authors: ÇÖTOK Tufan , KABİL Onur
Published: October 2023

Aristoteles’in teorik bilimler ile pratik bilimler arasında yaptığı ayrım iki tür akıl yürütme tarzına yol açar. Teorik bilimlerin konusu nesnesi değişmeyen varlıklar iken, pratik bilimlerin konusu olumsal özelliğe sahip olan eylem alanıdır. İnsanı eyleme geçiren temel saik tercihtir ve her tercihin arkasında pratik akıl yürütme (logismos) bulunur. Zengin bir anlam içeriğine sahip olan ve bu zenginliğin nedeni kabul edilebilecek ‘logos’ kavramından türeyen logismos kavramı, eylemin tercihi hususunda belirleyici olan kavramlardan biridir. Aristoteles’e göre pratik alanda akıl, klasik doğruya ulaşma çabası olan ve teorik akıl yürütmenin temel aracı olan teorik kıyasta olduğundan farklı bir şekilde işlem yapar. Çünkü söz konusu olan alan, belirtildiği üzere olasılığın söz konusu olduğu alandır. Dolayısıyla logismos’un anlamını açık kılmak için yapılması gereken ilk şey onun teorik kıyas ile farkını tespit etmektir. Bir eylem gerçekleşirken fail nasıl akıl yürütür ve bu akıl yürütme, klasik Aristotelesçi akıl yürütme olan teorik kıyas ile nasıl bir ilişki içerisindedir? Her şeyden önce pratik akıl yürütme istenen, arzu edilen bir şeyi dile getiren ve bir de bir algısal yargıyı, bir durumu belirten en az iki öncüle sahiptir. Buna karşın bu öncüllerden çıkarılan sonuç teorik kıyasdakinin tersine bir önerme değil, eylemdir. Pratik akıl yürütme biçimsel olarak teorik kıyasdan farklıdır ve teorik kıyasın sahip olduğu kesinliğe sahip değildir.
FİLİSTİN KURTULUŞ ÖRGÜTÜ’NÜN (FKÖ) DİPLOMASİ SERÜVENİ: OSLO BARIŞ SÜRECİ
Authors: KAYA Mehmet , POLAT Elif
Published: October 2023

1990’ların başında “Ortadoğu Barış Süreci” olarak adlandırılan süreç, Arap-İsrail çatışmalarını kapsayan yeni dünya düzenin tartışıldığı ve Sovyet Rusya’nın yıkılması ile sona eren Soğuk Savaş’ın ele alındığı bir dönem olmuştur. 1990’lardan itibaren kullanılan “barış süreci” kavramının uluslararası konjonktürde popülerlik kazanması, bir araya gelemeyecek tarafların diyalog yolu ile sorunlara çözüm bulmaya çalışması sayesinde olmuştur. Bu çalışmada, bölgesel dönüşümler ışığında Filistin ve İsrail özelinde başlayan diyalog süreci ele alınarak tarafların “barış için toprak” ilkesi çerçevesinde sorunlara çözüm aradıkları ve birbirlerini ilk kez resmi olarak tanıdıkları, gizli görüşmelerle başlayan Oslo Barış Süreci incelenmiştir. Bölgesel hegemonya yarışından zaferle çıkan ABD’nin, İsrail-Filistin çatışmasını sonlandırmaya yönelik sürdürülen barış görüşmelerinde öncü rol oynamak istemesi, bölgesel liderliğini pekiştirerek prestijini yükseltmeye çalışması, Sovyet Rusya’nın boşalttığı alanları doldurma yolundaki girişimleri, Ortadoğu’daki diyalog ve çatışmasızlık perspektifinde incelenmiştir. Büyük umutlarla başlayan ve İsrail ile Filistinli yetkililer arasında yaklaşık on sene süren diyalog ortamında elde edilen kazanımların, ülkelerin iç dinamikleri ve güvenlik algılarının ortak noktada buluşamaması, tarafları başladıkları yere geri götürmüştür.

Este artículo tiene como objetivo abordar los mecanismos de resistencia colectiva que las mujeres rurales despliegan a partir de las transformaciones en la habitabilidad rural del Valle del Aconcagua en Chile. La investigación se desarrolla en las zonas rurales de Pullalli y Olmué —con base en una etnografía encarnada colaborativa—, mediante técnicas de historias de vida con mujeres rurales en talleres colectivos y entrevistas abiertas a agentes clave, para dar cuenta de las agencias que se generan desde la habitabilidad del cuerpo. Los hallazgos evidencian que las mujeres movilizan sus agencias desde la vinculación del cuerpo, el territorio y las desigualdades del sistema sexo/género. Se establece la sostenibilidad de la vida como un engranaje que suscita dinámicas de crisis y exposición, pero también de movilizaciones y acciones que se asientan en los procesos territoriales que devienen de la escasez hídrica, las marcas territoriales corporales y la creación de redes de solidaridad.
Investigating the Potential for Standardization of Glass Reinforced Polymer (GRP) Shutter Molds Designs in Bridge Projects in the UAE
Authors: Alzaim Mhd Amer , Al Ali Mariam , Abu-Lebdeh Ghassan
Published: October 2023

This paper addresses the potential for design standardization of bridge construction moulds as a means to minimize waste and cost. Specifically, the paper looks at the potential for standardizing the design of bridge Glass Reinforced Polymer (GRP) shutter moulds that typically vary in size and design based on project-specific requirements. Environmental and economic sustainability aspects are addressed using a two-tiered approach views of construction experts were solicited, and production-to-demolition and disposing costs of a sample of completed projects estimated. There appears to be a consensus that there are significant benefits from standardizing the design of the modes including material waste reduction, cost savings, shorter procurement processes and possibly the reuse of shutter moulds. Given the size of the construction sector and its contribution to material and energy consumption and harmful emissions, and non-hazardous waste, the potential savings are significant.

Published: October 2023

Existing research reveals that by adopting leading technologies in the construction industry, worker's safety could be maximized. Presently, the application of technologies to promote safety in the construction sector is limited. The data for accident cases on the construction sites are very limited. Many tools and techniques have been created to increase worker safety on construction sites by designing and implementing good safety plans. A bibliometric and scientometric approach was used to identify the most prominent technologies in construction safety management. The data was retrieved from WOS database, and the analysis of the study is based on using VOS viewer to visualize the domain-specific knowledge. This study helps in the identification of emerging digital technologies such as Building Information Modelling (BIM), IT applications, Augmented Reality (AR) and Virtual Reality (VR), its application, and barriers in adoption during safety management. This study also highlights critical factors that promote technology adoption in construction safety management. This research also traces the current trends, future directions and supports crucial knowledge on safety technology to construction researchers and practitioners.
Offsite Construction in the UK: Economic and Environmental Benefits
Authors: Sadabad Mohammad Maleki
Published: October 2023

In contrast to traditional piece meal onsite construction, offsite construction comprises the planning, designing, production, transporting, and assembly of building elements for speedy site assembly to a higher degree of completion. Offsite building utilises a wide range of materials, scales, and systems, as well as modern manufacturing and fabrication techniques and computer software. Offsite construction is utilised to create componentised, panelised, and modular elements that support structural, enclosure, service, and interior partition systems. Integrating these systems with the supply chain through research, design, testing, and prototyping is an off-site optimisation technique. Due of economic, health and safety, and environmental factors, major UK contractors have adopted offsite construction over the past decade. Large projects are requiring major contractors like Mace, Laing O' Rourke, and Balfour Beatty to invest in off-site manufacturing. Offsite construction is defined in detail in this paper, along with how it can help construction projects to succeed economically and environmentally. The impact of offsite construction was examined in this research using a narrative review of the existing literature, and the findings demonstrate that there are numerous advantages both economically and environmentally. Offsite construction is more environmentally friendly because it requires less energy and large machinery uses on site. Since it is simpler to anticipate the amount of material required and buy in bulk, the organisation may reduce waste and the number of vehicles required to transport the finished product to the site. Cost savings always result from transferring site processes to a production workshop setting. The cost of labour in mechanical and electrical installation is one of the highest costs in construction industry, therefore, as prefabricated solutions have been fully or partially completed before they arrive on-site, labour can be reduced with offsite construction.
Why Construction Projects are delayed in PWA: Problems and Solutions
Authors: Al Marri Dana Ahmad , Al Kaabi Noof Mohamed
Published: October 2023

Construction is, by its nature, complex and uncertain. Changes and variations are inherently part of many construction projects, which require serious efforts to overcome. Project delay is a construction problem resulting in contractual claims, increased project cost, and decreased end-user satisfaction. This study investigates the root causes of project delay in Public Works Authority construction projects and gathers different perceptions on the causes of delay to propose a solution matrix that mitigate the effect of those delays and prevents its reoccurrence in future projects. A sample of over two-handed projects in 2021 have been granted an extension of time to its original completion date have been studied to identify and analyse the root causes of project delay and the risk relevant to the project delivery being prolonged. For these reasons, a categorization of delay has been adopted, and every cause of delay has been coded. The method adopted to identify the top root causes of project delay was the Pareto Analysis (Pareto analysis is premised on the idea that 80% of problems can be traced to 20% of the causes). The result of the study was the development of a holistic solution matrix to address the root causes of delay. The solution consists of two parts, (1) identify the relevant corrective, immediate and preventive actions, and (2) develop a responsibility matrix for the implementation of those solutions to ensure its governance.
Early Thermal Cracking Control of Concrete Structures in Qatar

Published: October 2023

Thermal cracks can occur in concrete elements at early stages during the hardening process. Also, the impact of thermal contraction and drying and autogenous shrinkage, may lead to excessive tensile strains and as a result cracks will occur. Consequently, an increase in reinforcements may be required to satisfy Early Thermal Cracking (ETC). ETC remains a major concern for concrete structures, especially for structures with high demand of water tightness. Considering the significance of water leaking in underground structures and the rising of the groundwater table in Qatar in the recent years, the Public Works Authority (ASHGHAL) has set the criteria to control early thermal cracks for Highway and Drainage Structures. This paper aims to present a comparison between the Early Thermal Cracking (ETC) codes and guidelines aiming towards providing sustainable and efficient design. This study compares the design method and parameters considered in BD 28/87, CIRIA C660 and CIRIA C766 currently used in Qatar for ETC calculations such as crack width permissible limit, minimum area of reinforcements, temperature change at early age, long term ambient temperature, autogenous shrinkage, drying shrinkage and restraint conditions. In addition, ETC calculations are carried out for a tunnel reinforced concrete box section with wall and top slab thicknesses ranging from 300mm to 1000mm. The least required area of reinforcements (As,req) for wall subject to edge restraint was by CIRIA C766 and for top slab subject to end restraint was by BD 28/87.
A Static and Free Vibration Analysis of Porous Functionally Graded Beams
Authors: Hadji Lazreg , Plevris Vagelis , Madan Royal
Published: October 2023

In this work, the static and free vibration analysis of functionally graded (FG) porous beams is investigated using a new higher-order shear deformation model (HSD). The porosity that develops naturally during the fabrication of a material is arbitrary in nature. Therefore, in the present study, a variation is considered taking into account three distribution patterns, namely (i) even distribution, (ii) uneven distribution, and (iii) the logarithmic-uneven pattern. Furthermore, the impact of several micromechanical models on the bending and free vibration behavior of the beams was investigated. Different micromechanical models were used to examine the mechanical properties of functionally graded beams, the properties of which change continuously throughout the thickness following a power law. Using the HSD model, the equations of motion are obtained using Hamilton’s principle. To obtain displacements, stresses, and frequencies, the Navier type solution method was employed, and the numerical results were compared to those published in the literature. The impact of porosity and volume fraction index, different micromechanical models, mode numbers, and geometry on the bending and natural frequencies of imperfect FG beams were investigated.

This study reports the statistical significance of using Graphene Oxides (GOs), Graphene Nanoplatelets (GNPs) and Carbon Nanotubes (CNTs) on the mechanical properties of cement paste. Samples containing several nanoparticles' weight fractions were prepared and tested for flexure and compression. The testing results were then statistically analysed using the t-statistical method to investigate the significance of using Nanomaterials on the properties of cement paste. The results highlighted the significance of using GOs and CNTs on the flexural strength of cement paste. Mixes containing 0.04% GOs, 0.08% GOs and 0.12% CNTs could enhance the flexural strength by at least 45% compared to the plain control mix. On the other hand, test results showed the significance of using 0.04% GNPs, 0.08% CNTs and 0.12 % GOs in increasing the compressive strength of cement paste by at least 10% compared to the plain control mix. Microstructural analysis using Scanning Electron Microscope (SEM) showed that proper Nanofilaments dispersion in most batches. Furthermore, the analysis highlighted the nanoparticles' impediment within the cement hydration products.

Starting in 2018, Musaimeer Pumping Station and Outfall Project (MPSO) was constructed to manage ground and storm water received from 270 km2 area of southern Doha, Qatar. The project consists of a pumping station, subsea tunnel, (constructed through Rus formation, Midra shale and Simsima limestone), riser shaft and diffuser bed structure. An Earth Pressure Balance (EPB) Tunnel Boring Machine (TBM) was used for subsea tunnelling where ground water inflows, mixed ground condition with the presence of vertical and lateral fractures connected to the seabed were encountered during tunnelling activity. This paper analyses the reliability of geotechnical investigation results and interpretations by comparison with encountered conditions. This will be beneficial to design a reliable geotechnical investigation programme for future projects of similar scope in the state of Qatar. Results and interpretations from drilled bore holes and geophysical survey provided an overall picture of underground conditions along the tunnel alignment, which identified the critical tunnelling areas for cutter head intervention and maintenance. These results were then compared with the built geotechnical conditions accessed by collecting data through the onboard TBM monitoring equipment, collecting rock mass samples, and performing geological face mappings during tunnelling activity. Comparison of pre-tendered investigation results with the built geotechnical conditions concluded that investigation results and encountered rock mass conditions were in line with each other. Geotechnical investigation programme followed for this project and interpretation as a result, made the tunnelling under sea to be carried out in more careful and low risk manner.

Published: October 2023

Sinkholes are a common and recurring problem with potential safety risks to road users and authorities. A sinkhole is a void in the ground caused by natural and/or manmade activities, and mainly associated with carbonate rocks and underground water movement. It occurs suddenly and manifests as a hole in the ground, with the potential to cause significant problems of road closure and interruption to road users and construction activities. With the vast infrastructure, development over the last two decades and the majority of soil formation of Qatar exposes limestone and dolomites, the number of reported sinkholes has increased dramatically. This paper presents the development and implementation of new guidelines for the evaluation and repair of sinkholes for the Roads Operation and Maintenance Department (ROMD) at the Public Works Authority (Ashghal). It reviews the methodology adopted for the classification of sinkholes, application of Ground Penetrating Radar (GPR) technique for the early detection of subsurface voids and sinkholes before they become major problems. It also covers the approach adopted by ROMD and its Framework Partners for the repair of sinkholes. A case study is presented on the implementation of the new guidelines for the effective evaluation and repair of sinkholes, with performance monitoring in service. Successful implementation of the new guidelines contributes to enhanced management of road network in Qatar by maximizing asset performance and minimizing accidents and service disruption.

Authors: Al-Kuwari Mohammed Bin Saif , Hassan Khaled E.
Published: October 2023

Volumes of accumulated solid waste materials of sewage sludge (SS) and municipal solid waste (MSW) in Qatar continue to increase annually with a potentially negative impact on the environment. This paper presents an innovative technology for the production of green cement and advanced construction products from SS and MSW. Chemical composition analyses of the solid waste materials indicated the presence of main oxides available in Portland cement, but at lower contents. The three solid waste materials were incinerated and ground to produce consistent powder materials of similar sizes to Portland cement. The physical and chemical characteristics of the solid waste materials were investigated and compared to that of Portland cement. Paste and mortar mixtures were prepared by replacing 25, 50, and 75% of Portland cement with the different solid waste materials. Solid waste materials were found to influence the fresh properties of concrete, mainly water demand and setting time. Increasing the content of solid waste materials resulted in reduced compressive strength at all tested ages. SS gave the best performance within the solid waste materials investigated. Recommendations are made on the effective use of solid waste materials in various construction applications.

Published: October 2023

As a result of numerous infrastructure projects which have taken place in Qatar in the last decade, there has been an unprecedented increase in demand for construction materials. In addition, the huge program of infrastructure development has led to production of massive quantities of construction waste. Consequently, the Public Works Authority of Qatar (Ashghal) launched an initiative to use recycled materials in projects in line with Qatar National Vision 2030 and Qatar National Development Strategy 2018 - 2022. A roadmap was developed in 2018 considering the available resources and experiences. Recyclable materials which can be used in Ashghal projects were identified. Excavation waste, demolition waste, Reclaimed Asphalt Pavement (RAP), Wadi Aggregate, Crumb Rubber and Steel Slag were selected for reuse. Controlled logistic areas to store, manage and process recyclable materials were established. Moreover, guidelines and prequalification procedures were developed for both materials sources and recycled materials producers. Testing programs were carried out on these materials to identify their basic characteristics. Laboratory trials and field trials were carried out at selected projects. Field trials were monitored and assessed using the local construction specifications QCS 2014. Based on lab and field trials, customized specifications were developed for the utilization of the selected recyclable materials in Ashghal projects. These specifications establish the baseline for construction using the selected recycled materials and determine the criteria and methods needed for quality control. Furthermore, Key Performance Indicators (KPIs), were established for Ashghal project departments to monitor their performance in relation to recycling. Ashghal's phenomenal performance in utilization of recycled materials in the last three years is presented.

Authors: Mohammed Almodather , Al-Saudi Ali , Al-Marri Mohammed
Published: October 2023

This case study addresses peak hour traffic timing in Qatar after COVID-19 as traffic conditions returned to normal. Traffic data were provided for multiple areas, mainly around Doha City. Flow data were obtained from traffic signal detectors for 318 intersections. The peak periods in morning, mid-day, and evening were 06:30 am–08:30 am, 12:30 pm–2:30 pm, and 5:15 pm–7:15 pm, respectively. These findings align with the Ministry of Transport’s state-wide study (Transportation Masterplan for Qatar, 2018). We found traffic in Qatar to differ on Thursday, Friday, and Saturday versus the rest of the week due to the weekend effect. Results offer useful insights for policymakers to reduce congestion and provide complex traffic solutions (e.g., understanding land use–specific peak hour timing, imposing zone-specific working hours). In addition, this case study highlights the potential to use existing infrastructure to expand traffic studies in Qatar at minimum cost.

Authors: Roy Bidhan Chandra , Bhattacharyya Satyaki
Published: October 2023

Nairobi, famous for Nairobi National Park, the world’s only game reserve found within a major city, started developing as a rail depot on the Uganda Railway. In 1963, Nairobi became the capital of the Republic of Kenya and showed phenomenal growth in terms of population ever since (from 11,500 in the year of 1906, to 3,138,369 by Year 2009, at growth rate of 4.1% a year). The city of Nairobi has experienced rapid urban sprawl. In 1970, average commuter distance was 0.8 km and increased to 25 km in 1998. Present commuter distance is over 40 km. The long commuter distances and heavy traffic congestion on the road has led to long travel time. At this rate, the difficulties commuting to the central business area is getting more and more complicated. The need of the hour is developing a world-class transport network, a combination of Road and Rail Based Mass Rapid Transit System (hereinafter mentioned as MRTS or MRT) technology. A comprehensive study was carried out in this direction to find out the feasibility of such MRTS in early 2000s. Based on the findings of the study, further study was conducted in 2013-2014 for developing the basis for a technical and financial harmonisation of measures. In 2019, the NMA Council gazetted 5 BRT and 7 Commuter Rail corridors vide Legal Notice No. 16 of 26th February 2019, which is outcome of all the efforts. This paper aims to put together the outcome of studies made so far.

Authors: Asaduzzaman Md. , Sadat Nafis
Published: October 2023

Being a developing country, Bangladesh has faced rapid growth in urbanization in the past few decades. This results in decreasing parks and other green spaces in urban areas. Rajshahi is one of the divisional districts in Bangladesh that is prone to rapid urbanization, though the urbanization rate of Rajshahi is less than the other megacities in Bangladesh. As a result, it is important to preserve the parks in Rajshahi before they are diminished. To assess the quantity and preserve the present urban green infrastructure in Rajshahi, it is necessary to identify and categorize them according to their regional characteristics. This paper aims at evaluating the urban green spaces in Rajshahi and finding out whether the existing urban green spaces are enough to meet the goal of a sustainable city. It is done by analyzing the regional characteristics of urban parks and green spaces located in Rajshahi, Bangladesh, based on GIS data and categorizing them according to their physical size to determine their catchment area. Statistical data and aerial images are processed and simulated through ArcGIS software and correlated with cadastral plans for accurate identification. Explanatory factors regarding UGS loss in a specific region are also investigated using socio-economic, cultural, and geographic in order to find out the reason for UGS change. The resultant data shows that only "6.14 " m2/capita urban open space is available for the urban inhabitants which are insufficient for achieving sustainability goals and should be preserved in order to enhance the liveability of the city.

Published: October 2023

The construction industry is faced with several Environmental, Social and Governance (ESG) challenges and opportunities that include, but are not limited to, a massive carbon footprint, the physical impacts of climate change, green building certifications, supply chain, innovative product design, pollution control, health and safety, diversity and inclusion, community development, business ethics, and biodiversity. With these ESG issues front and centre in daily headlines, investors, shareholders and all other stakeholders are demanding greater transparency in relation to the construction industry's interaction with the environment and the society in which they operate and upon which they depend for long-term business continuity. ESG factors are becoming fundamental nonfinancial information for the long-term valuation of a company, for the investment decision-making process and in determining capital allocations. All the key players in the construction industry, including engineering and construction services firms, manufacturers and distributors of construction materials, buildings products and furnishing companies, real estate developers, and real estate services companies, need to convince stakeholders that they are delivering optimal outcomes when it comes to the triple bottom line of people, planet and profit. In this paper, we will address and discuss the following questions: What are the key ESG challenges and opportunities that construction industry is facing? How are these key ESG challenges identified and acted upon? What are the enablers used by the construction industry to address and manage ESG factors? Among these enablers, we will look in details at the Global Sustainability Assessment System (GSAS) and its capability to satisfy the investors ESG disclosures needs.
