Development Of A New Electro-Osmotic Consolidation Apparatus, Yenni Mariana Ramírez-Mazo, Juan Pablo Osorio, Sergio Agudelo
Development Of A New Electro-Osmotic Consolidation Apparatus, Yenni Mariana Ramírez-Mazo, Juan Pablo Osorio, Sergio Agudelo
Conference papers
Electro-osmotic consolidation is a ground improvement technique in which a DC voltage is applied to the soil via electrodes, in order to drain the water contained in the pores increasing the effective stress, and thus improving the geotechnical properties of the soil. The technique increases the shear strength, reduces the compressibility, and changes the chemical composition of the saturated soft clayey and silty soils to which it can be applied. Electro-osmotic consolidation has been successfully applied in different projects worldwide. This paper presents the development of a new electro-osmotic consolidation apparatus built at Universidad de Antioquia. Tests were carried on …

Self-healing asphalt, which is designed to achieve autonomic damage repair in asphalt pavement, offers a great life-extension prospect and therefore not only reduces pavement maintenance costs but also saves energy and reduces CO2 emissions. The combined asphalt self-healing system, incorporating both encapsulated rejuvenator and induction heating, can heal cracks with melted binder and aged binder rejuvenation, and the synergistic effect of the two technologies shows significant advantages in healing efficiency over the single self-healing method. This study explores the fatigue life extension prospect of the combined healing system in porous asphalt. To this aim, porous asphalt (PA) test specimens with …
The Role Of Rejuvenators In Embedded Damage Healing For Asphalt Pavement, Shi Xu, Xueyan Liu, Amir Tabakovic, P Lin, Y Zhang, S Nahar, B J. Lommerts, Erik Schlangen
The Role Of Rejuvenators In Embedded Damage Healing For Asphalt Pavement, Shi Xu, Xueyan Liu, Amir Tabakovic, P Lin, Y Zhang, S Nahar, B J. Lommerts, Erik Schlangen
Articles
Rejuvenator encapsulation technique showed great potential for extrinsic asphalt pavement damage healing. Once the capsules are embedded within asphalt pavement, the healing is activated on-demand via progressing microcrack. When the microcrack encounters the capsule, the fracture energy at the tip opens the capsule and releases the rejuvenator. Then the released rejuvenator wets the crack surfaces, diffuses into and softens the aged bitumen, allowing two broken edges to come in the contact, preventing further asphalt pavement deterioration. The quality and speed of the damage repair process strongly depend on the quality of rejuvenator, thus it is important to choose a proper …
To What Extent Can Innovative International Project Delivery Strategies (Which Leverage Bim) Improve The Cost Certainty Of Large Complex Public Procurement Projects In The Context Of Irish Public Procurement?, Bim Tudublin, Roqaya Abouklaib
To What Extent Can Innovative International Project Delivery Strategies (Which Leverage Bim) Improve The Cost Certainty Of Large Complex Public Procurement Projects In The Context Of Irish Public Procurement?, Bim Tudublin, Roqaya Abouklaib
Capstone Reports
Cost overrun is one of the biggest issues in the construction sector, and cost certainty is one of the main aims of the public construction sector in Ireland. Studies have shown that multi-disciplinary collaboration will benefit a construction project throughout its lifecycle. BIM, Lean, and IPD are independent methodologies that encourage collaborative work, and there are existent effective synergies among these concepts. The synergetic innovative international strategies were utilised for delivering large complex projects successfully globally, and many authors have studied large complex public projects that have adopted innovative international project delivery strategies collaboratively and have shown that the cost …

A Critical Examination Of Visual Programming And Generative Design For The Compliance Checking Of Open Plan Office Layouts Against Hse Guidelines Post Covid-19., Bim Tudublin, Ronan Byrne
Capstone Reports
The purpose of this study is to explore the feasibility of Visual Programming (VP) and Generative Design (GD) in assisting employers review open plan office layouts against Ireland’s HSE guidelines implemented in May 2020 in response to Covid-19. The pandemic has affected all areas of life with workplace standards requiring a complete overhaul. This study will attempt to ascertain compliance with natural ventilation and social distancing requirements through the completion of an experimental research study, utilising Computational Design (CD) tools. A GD study will be undertaken to provide the designer with numerous office layout design solutions to evaluate and evolve. …

The unprecedent events which transpired in the 88-day period from the 31st of December 2019 to the 27th of March 2020 have changed the world in which we live and work. The outbreak of Coronavirus disease 19 (COVID-19) and the ensuing pandemic which has evolved are descripted as one in a hundred-year events. This paper researched and critically analyses the operations which large Irish Architecture firms initiated during this period in order to facilitate the ability of its employees working from a remote location, focusing on how the People, Processes and Policies of BIM (3 Ps of BIM); adapted to …

Should Acoustic Simulation Technology Be Utilised In Architectural Practice? Does It Have The Potential For Bim Integration?, Bim Tudublin, Keith Harvey
Capstone Reports
The research presented in this paper, firstly, aims to convey the importance of our acoustic environment through focusing on the effects of undesirable acoustic conditions on cognitive abilities in spaces where cognitive performance is of the utmost concern, our learning environments. Secondly, it aims to investigate current state-of-the-art acoustic simulation methods, available platforms, and their levels of interoperability with architectural BIM authoring software. Structured interviews were carried out with 7 Irish architects and architectural technologists to determine if a disconnection between architectural design and acoustic performance exists and to identify the advantages and disadvantages of current workflows for acoustic performance …

An Examination Of The Use Of Geotechnical Bim To Provide Value Engineering Solutions For Coastal Infrastructure., Bim Tudublin, Eric Brennan
Capstone Reports
The digitisation of construction is taking root as Building Information Modelling is becoming more prevalent across the industry. From an Irish context, the adoption rate of BIM has been slow; nationally its advantages and merits have been welcomed and the appropriate government support is either available, soon to be implemented or in the early conceptual stage. Within the Irish governments Project Ireland 2040 framework there are significant infrastructure developments looming ahead, in particular regarding ports and harbours. The importance of this type of infrastructure is only further compounded due to the UK’s departure from the EU and the need for …

Ireland has one of the highest rates of emissions per capita in the world and its residential sector is responsible for approximately 10% of total national CO2 emissions. Therefore, reducing the CO2 emissions in this sector will play a decisive role in achieving EU targets of reducing emissions by 40% by 2030. To better inform decisions regarding retrofit of the existing building stock, this study proposes Optimum Insulation Thicknesses (OIT) for typical walls in 25 regions in Ireland. The calculation of OIT includes annual heat energy expenditure, CO2 emissions, and material payback period. The approach taken is based on Heating …
