Inspect: Intelligent Node-Based System For Ifc Processing And Evaluation, With Conversational Tool Support —Llmassisted Natural Language Ifc Querying, Basel Abdelshaheid

Theses and Dissertations

Industry Foundation Classes (IFC) enables the open exchange of Building Information Models, yet effective validation of real-world IFC deliveries remains challenging. Project models frequently contain incomplete, inconsistent, or incorrectly exported metadata, and explicit IFC relationships are often missing or degraded during conversion from proprietary formats. Many validation questions are inherently spatial, including connectivity, containment, proximity, and clashes, and therefore cannot be answered reliably from properties alone. As a result, federated model validation is often slow, fragmented across tools, and dependent on specialized IFC expertise.

This challenge is increasingly important for coordination, quality assurance, and information management across disciplines and lifecycle …

Theses and Dissertations

Plastic recycling has emerged as a crucial strategy that aligns with environmental, social and economic sustainability indicators. Currently, substantial volumes of plastic waste are either deposited in landfills or incinerated, neglecting the potential to harness its embodied energy and the energy consumed for producing virgin materials. A key advantage of plastic lies in its promising mechanical properties. Concrete mix design is fundamental to a wide range of construction applications, including brick walls, reinforced concrete slabs and concrete pavements. Despite the adoption of recycled plastic in construction materials in various countries, its widespread implementation remains limited. This is primarily due to …

A Machine Learning Framework For Predicting Fabrication Hours For Industrial Steel Structure Projects, Dalia Ibrahim

Theses and Dissertations

Construction projects are considered high risk projects especially due to their required large capital making them require extreme attention in estimation as overestimating a project will lead to losing bids and underestimating them will lead to incurring more costs than budgeted resulting in losses. However, estimators are often faced with very tight timelines to finish their estimates leading them to primarily rely on their experience disregarding some crucial factors resulting in inaccurate estimates. In the steel structures industry, the steel fabrication phase accounts for 30 to 40% of the overall project cost; in addition, the steel industry is labor driven; …

Towards A Sustainable Model For Finishing Materials In Mixed-Use Gated Community Buildings, Dina Mohamed Shawky Ismail

Theses and Dissertations

ABSTRACT

The concept of sustainability has recently become widespread, and most industries attempt to fulfill all requirements to qualify as sustainable. The construction industry is a prime polluting activity that contributes significantly to carbon dioxide (CO₂) emissions. Moreover, use of specific finishing materials such as paint and coatings adds to the emission of volatile organic compounds (VOC) which are extremely harmful to the human health. Hence, proper choice of building and finishing materials can potentially reduce such emissions and takes the building a step closer to qualify a building as a sustainable one. While the construction industry in …

Framework For Enhanced Applicability Of The Egyptian Public Procurement Law To International Administrative Construction Contracts, Amr Abu Helw

Theses and Dissertations

Local governments and public authorities conclude contracts for the purpose of acquisition of goods, delivery of services and construction of public facilities like bridges, infrastructures and public buildings. A public contract is an agreement to perform particular tasks financed by government funds to the benefit of the whole community. Private entities and corporations are subject to stricter standards in their dealings with the government than in private transactions. Conversely, the government must deal fairly and equitably with those who it contracted with to achieve successful implementation of the projects. On October 3, 2018, a new Egyptian public procurement law, namely, …
