With the existence of studies that confirmed that the quality of Built Environment (BEQ) is the most important factors that affect the quality of life, and In light of the absence of quality in the Egyptian built environment in one or more of its aspects and its repercussions on the behaviors of people living in it, which led to a decrease in the quality of life in general, this research paper seeks to present a model for a comprehensive framework for assessing the BEQ in general. To achieve this goal, a deductive approach is adopted by analysing built environments rating systems, identifying the concept of quality generally and BEQ, starting with the concept of quality, its aspects, and methods of measurement, and to analyse the current methods of assessing BEQ to check its comprehensiveness, followed by the proposed conceptual framework for assessing BEQ and its basic pillars. As a result, a conceptual framework for assessing the BEQ including its pillars and the mechanism of work was proposed. It could be a base for establishing a system for assuring and assessing the quality of the built environment in Egypt as the paper recommend. [ABSTRACT FROM AUTHOR]

Egypt's construction sector faces enormous challenges related to the construction phase, the most important of which is a considerable waste of effort, time, and money that may result in increasing the risk of losing projects. Indeed, eliminating such a waste will certainly improve the project performance, thereby enhancing the value of the project stakeholders. The researcher assumes that adopting lean construction (LC) approach is necessary to reduce waste, improve performance, and enhance the performance of the Egyptian construction sector at large. The research relies on a simplified methodology that has several positive outcomes: (1) saving time and cost; (2) boosting quality and safety; and (3) improving management process control, resource management, and relationships between project team members. Therefore, the main objective of the current paper is to examine and analyse the ability of wasteless construction principles to reduce waste in the construction process through an applied case study of a large construction project in Egypt. The study employs lean construction (LC) methodology and utilizes its technologies and tools to reduce waste in construction, particularly at the finishing stage, measuring their effectiveness in achieving the desired goals. The study assumes to have two major contributions: (i) determining the main causes of waste in the Egyptian construction industry; and (ii) applying LC methodology to prevent and eliminate the causes of waste inherent in the construction process.

Parametric design is called many meanings, including boundary design, modelling, standard design or variable design all lead to parametric meaning. Parameter design is an architectural approach that uses vocabulary in the light of a set of rules and design patterns that achieve design objectives in the presence of a design idea And research finds that the problem is that such a contemporary approach to design is rarely used in Egypt, although it is widely used around the world and in countries that share with Egypt the cultural heritage, nature and environmental condition, But the complexity of using programming techniques in design without studying or knowing the vocabulary on which the parameter and the associated formation rules depend directly affects design thinking and, in turn, affects the cost because it needs various and modern implementation techniques.. Therefore, the research aims to derive the vocabulary of the parametric approach and to identify the rules and patterns of this contemporary design approach. The paper addresses the different concepts of parameter design, the main principles on which it relies and the basic patterns on which the architect can identify the features of the parameter building. The study found that the parametric approach has been proven to be efficient using various modes of formation and various architectural vocabulary in achieving all design objectives. The research recommends using the benchmark for architectural design equation in identifying and analyzing parametric buildings in light of patterns and rules to reach the parametric vocabulary to achieve different design Features.
