With buildings around the world accounting for nearly one-third of global energy demand and availability fossil fuels constantly on decline, there is a need to ensure that this efficiently effectively managed using renewable now more than ever. Most research case studies have focused efficiency ‘new’ buildings. In study, both technical financial viability Net Zero Energy Buildings (NZEB) ‘existing’ will be highlighted. A rigorous review open literatures concerning seven principal areas in...

Over the past centuries, millions of bridge infrastructures have been constructed globally. Many those bridges are ageing and exhibit significant potential risks. Frequent risk-based inspection maintenance management highway is particularly essential for public safety. At present, most rely on manual methods management. The efficiency extremely low, causing risk deterioration defects to increase day by day, reducing load-bearing capacity bridges, restricting normal safe use them....

Innovative digital twins (DTs) that allow engineers to visualise, share information, and monitor the condition during operation is necessary optimise railway construction maintenance. Building Information Modelling (BIM) an approach for creating managing inventive 3D model simulating information useful project management, monitoring of a specific asset whole life cycle assessment (LCA). BIM application can help provide efficient cost management time schedule reduce delivery throughout...

Railway track health monitoring and maintenance are crucial stages in railway asset management, aiming to enhance the train operation quality service life. For this aim, various inspection means (using diverse non-destructive testing techniques) have been applied, however, these mostly not able monitor whole network or underlying layers (e.g., ballast subgrade). The use of remote sensing techniques, such as Interferometric Synthetic Aperture Radar (InSAR), can expedite defect diagnosis...

Recycled concrete aggregate (RCA) has been widely adopted in construction and emerged as a sustainable alternative to conventional natural aggregates the industry. However, study of holistic perspectives recent literature is lacking. This review paper aims provide comprehensive analysis RCA, highlighting its properties, applications, overall sustainability benefits facilitate points view technology, ecology, economics. explores manufacturing process examines mechanical durability...

The railway station is a primary asset of public transport systems and plays crucial role in urban modernization. Most existing stations the UK historic have been operated for many years. Maintenance reconstruction are common concerns industry, clusters information pertaining to this maintenance must be managed appropriately effective outcome. Digital twin or BIM (Building modeling) term frequently employed construction industry nowadays, because its ability provide wider faster access...

In recent years, railway systems have played a significant role in transportation due to the demand increase conveying both cargo and passengers. Due harsh environments severe loading conditions, caused by traffic growth, heavier axles vehicles speed, tracks are at risk of degradation failure. Condition monitoring has been widely used support health assessment civil engineering structures infrastructures. this context, it was adopted as powerful tool for an objective track behaviour enabling...

Digital twin (DT) or so-called ‘building information model (BIM)’ has brought great revolution to the current building industry. Its applications life cycle management of buildings and infrastructures can further increase social economic benefits. As a complete model, digital integrates project from different stages into in order facilitate better asset communicate through data visualizations with participants. This paper unprecedently introduces digital-twin aided assessment evaluate subway...

There is no doubt that the use of waste rubber in concrete applications a genius alternative because Styrene main component rubber, which has strong toxicity and harmful to humans. Therefore, it will significantly reduce impacts on environment when can be recycled for genuine uses. In this paper, dynamic properties high-strength rubberised have been investigated by carrying out various experiments retain compressive strength, tensile flexural electrical resistivity, damping characteristics...

A number of bridge infrastructures are rising significantly due to economic expansion and growing numbers railway road infrastructures. Owing the complexity design, traditional design methods always create tedious time-consuming construction processes. In recent years, Building Information Modelling (BIM) has been developed rapidly provide a faster solution generate process integration information in shared environment. This paper aims highlight an innovative 6D BIM approach for lifecycle...

Abstract Railway maintenance is a complex and complicated task in the railway industry due to number of its components relationships. Ineffective results excess cost, defective structure components, longer possession time, poorer safety, lower passenger comfort. Of three main approaches, predictive trendy one, proven that it provides highest efficiency. However, implementation for cannot be done without an efficient tool. Normally, corrective when some things fail or preventive routine. A...

Structural responses of longitudinally coupled slab tracks (LCSTs) under extreme heat waves (EHWs) and the adaptability track reinforcement measures to cope with EHWs-related issues have been unprecedentedly investigated in this study. A novel finite element model (FEM) assess nonlinear mechanical behaviours LCSTs exposed temperature rise has established. The nonlinearities material constitutional properties, interfacial distribution are taken into account, FEM fully validated by...

This study investigates the engineering and mechanical properties of basalt fiber-reinforced (FRF) concrete, giving special attention to residual flexural strength dynamic modal parameters. These properties, which have not been thoroughly investigated elsewhere, are a precursor structural design applications for compliant structures (i.e., bridges, offshore platforms, railways, airport pavement). Accordingly, standard notched tests carried out assess concrete's with an additional 0.125%,...

Abstract Buildings are energy- and resource-hungry: their construction use account for around 39% of global carbon dioxide emissions; they consume 40% all the energy produced; responsible over 35% EU's total waste generation; about 50% extracted (fossil) materials. Therefore, present a significant challenge to meeting national international Net Zero targets reducing greenhouse emissions fossil resource use. The CircularB Project, is at heart this issue, which will underpin synergies...
