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, …

Precast concrete as we know it today has been introduced to our markets over the past several decades. Having similar advantages to that of old precast building methods, the road has been paved for wider use …

Assessment Of Carbon Dioxide Emission And Its Impact On High-Rise Mixed-Use Buildings In Egypt, Ahmed Salah Hamza

Theses and Dissertations

With Egypt's vision of 2030 focusing on sustainable development with a true emphasis on Carbon Dioxide (CO₂) emission reduction in the newly built cities and high-rise buildings, efforts are exerted on various levels towards accomplishing the vision’s goals. This is achieved through multiple tools and models associated with aiding the reduction of carbon emissions, yet not a clear one was introduced for the mixed-use buildings in Egypt.

Through this work, a significant gap was identified with respect to high-rise buildings carbon emission assessment in Egypt. This was a main driving force for this work in an attempt to …

Interactive Expert System For Budgeting World Bank Consultancy Projects, Yosra Rafat

Theses and Dissertations

Cost estimating and forecasting are key components of the budgeting of any construction project. However, conventional approaches may result in uncertainty and usually do not utilize the organizational knowledge of past projects. Ideally, performing a cost estimation under the best predictions of the relevant future conditions, is the best approach of economic analysis to evaluate the optimum value for money. With the rise of Artificial Intelligence techniques, there are now several Machine Learning (ML) methods that are being studied to capitalize on accuracy gains with regards to cost estimating techniques to increase reliability during the tendering phase. This research aims …

Assessment Of Contract Terms And Conditions For Lump-Sum Contracts, Omar Othman

Theses and Dissertations

A Contract is a tool that defines the obligations of the contracting parties and assigns the risk between them. Contracts are usually drafted to meet the interests of the owner by addressing the legal issues and liabilities. Meanwhile, less emphasis is placed on clearly communicating the contract terms and ensuring that all contracting parties comprehend their risks and obligations. In a country like Egypt, which has faced drastic economic and political changes in the past few years, and yet is experiencing a boom in the construction sector, many developers tend to draft contracts that might be legally complicated or lacks …

Multi-Skilled Labor Optimization With Partial Allocation Of Resources, Amira Saleh

Theses and Dissertations

The current practice of labor allocation in construction schedules assumes single-skilled workforce; meaning that each worker is assumed to be skilled in only one trade. In such practice, at any instance in the project lifecycle, some of the workforce become idle waiting for other labor types to complete their work. Traditionally, companies may relocate idle workers to other projects and return them back to their original project when needed again. This complicates the resource management process and is not often performed successfully, leading to schedule and cost overruns. Alternatively, project managers may keep the idle workforce at their projects because …

A Web-Based Change Control Management Toolkit For Lump-Sum Turnkey Contractors: Transformation To Third Generation, Ahmed Omran

Theses and Dissertations

Project deviations and changes are one of the key common particulars encountered in the Construction industry. Project changes can occur in different forms, may impact different pillars of the project, and can be caused due to the existence of various underlying factors. Mismanaging or lack of controlling these changes is one of the key contributing factors leading to project hardships. Contractors incur profit erosion, scope creep, and time slippages mainly by failing to have an effective project change management system enforced within its project execution philosophy. Such adversity is amplified for contractors engaging in lump-sum turnkey “LSTK” projects. Contractors encounter …

Using System Dynamics To Study The Effect Of Change Orders On Labor Productivity, Shrouk Gharib

Theses and Dissertations

Change orders in construction projects lead to numerous negative impacts, including loss of labor productivity, delays, and cost overruns. Owners and contractors are usually in disagreement when it comes to allocating the extent of responsibilities with respect to the resulting overruns. Each party tries to hold the other party fully responsible for such overruns through a series of claims and disputes. Several delay analysis techniques have been developed to aid in settling such disputes, however, they do not fully grasp the rippled impacts of change orders and do not assist parties in reaching consensus when it comes to finding the …
