“…However, practitioners are expected to utilize lean construction principles in practice more frequently and realize full potential of the lean construction philosophy [19]. It was noticed that the positive effects of lean principles and methods on project management become more obvious as project complexity and the corresponding level of risk rise [20].…”

Project delivery quality (PDQ) is a potential target of the construction team, which is working on enhancing this quality thru project stages: design and construction. A very important side of this work is study and research to investigate the critical factors affecting PDQ. Some former studies uncovered that the delivery methods: Design-Build (DB) and Design-Bid-Build (DBB) notably affecting PDQ. A study appraised the mentioned methods among several features, such as: time, communication, drawings …etc. This paper assumes that there are other critical features to be studied as it's believed to complete the appraisal among DB and DBB. The aim of this paper is to get sound results for deciding which of them will contribute in enhancing PDQ. The paper will run unstructured conversations with design and construction players: owners, consultants (design/supervision), and contractors. They were requested to provide their feedbacks regarding (6) chosen features among DB & DBB. Also, they were asked to justify their scores adding more details. Collected data was organized, tabulated, and analyzed, then discussed, and concluded.Being DB in nature, the involvement of the consultants was easier, as they were contracted to the main contractor (the direct participant in the project), and the contractor also has a closer and earlier involvement of the main contractor in the design process with more consideration of build-ability issues [1].DB is not a new method of project delivery; its roots go back to antiquity. P Thomas mentioned that the pyramids were built though DB, as well as Saint Paul's Cathedral in London, but it fell into disuse in the United States about the time of the Civil War, and gave way to the "new" design-bid-build process through the latter years of the 20th century [2]. Also, he said that the DB delivery of buildings makes it less expensive and more certain that owners will get high performance and sustainability from their new buildings and renovation projects.Although the importance of DB operational differences is widely accepted, there is as yet little agreement of their classification. Different rules and terminologies are used and some of the classifications are contradictory [3]. For example, Janssens D.E.L (1991) and Akintoye A. (1994) consider Design and Manage to be a DB variant [4, 5], while Masterman, J.W.E. (1992), in contrast, refer to Design and Manage as a management-oriented procurement system [6]. Quatman G.W. (2001) and Gransberg D.D et al. (2006) include Bridging as a DB variant [7, 8]. In Beard et al. (2001) classification framework however, Bridging is not regarded as DB, because it is more akin to traditional Design Bid Build and the client/owner is again in the position of warranting the completeness of the design to the bridging contractor [9].Also, it's worth mentioning that The Direct DB process is qualifications-based, which involves the selection of a contractor through negotiation, and the selection of the team is primarily based on qualitative criteria such as past performa...

“…A study [1] about residential buildings in Jakarta reveal that they are in slum condition because of the level of damage and quality deterioration of the building material and the level of building maintenance budget availability. The other example is in construction phase, there are some problem like project delay that caused by low productivity rates and cost overruns [2], there are complexity of the finishing works in high-rise apartment. Sack and Goldin [3] explains that the complexity for execution finishing works in high-rise building is made complex by the need to customize apartment to the varying requirements and designs of individual clients.…”

Construction project success depends on success of design. It is very rare previous research about the success of design as a determinant to the success of construction projects. The Whole System Design (WSD) approach in a planning of a high-rise residential property consider the success interrelatedness of both problems and solutions. It can help to create more sustainable designs. Nevertheless, designers often face several factors that exclusively reduce the rate of successful design i.e. design model and methods. One way to manage this issue is to reduce ambiguousness by using a whole system design approach. This study purposes to explore framework of Whole System Design approach for successful design. Application of literature review method is used to understanding the problem by analysing 20 articles about high-rise building, residential and whole system design. The result presents a mapping of several methods that used in previous research. It is to help more widespread the successful design in a high-rise residential property.

“…Nascimento et al (2017) developed and applied a new model namely Digital Obeya Room (DOR) that demonstrated the interactions between Building Information Modeling (BIM) and lean prin ciples to improve workflows, data analysis, and 3D visual management of construction planning and control. The lean and non-lean scenarios were compared by Erol et al (2017) through applying a Monte Carlo simulation model on residential building project. Research findings demonstrated that the utilization of practical LC principles may result in a considerable amount of time reduction in some activities of residential building projects.…”

The wastes in construction projects such as wastes in materials, time, resources and achieving customer needs can be minimized using the new philosophy of Lean Construction (LC). This paper proposed a two-level model based on fuzzy logic technique for evaluating Causes of Wastes (CWs) and lean implementation in construction projects. The probability of occurrence and importance of CWs were two input parameters in level 01 of the model, whereas the output was the level of waste. On the other hand, level 02 of the model depended on using three input parameters which were: level of waste, controllability level for CWs and lean implementation level, while the output was the lean effect. Several linguistic variables and logical rules were used for relating inputs and outputs and new indices were introduced. The model was applied and validated for data collected in two countries: Egypt and Kingdom of Saudi Arabia (KSA). Results demonstrated that the expected lean effect is found with a positive correlation with various levels of wastes and can be improved by increasing controllability and lean implementation levels. Regarding the comparative study between the two countries, distinct disparities in lean effect were clarified. Most measured CWs indices were different in both countries while indices values in KSA were higher than in Egypt either in waste, controllability or implementation levels. The results presented an optimum arrangement to reach an effective new lean evaluation model that could be implemented for moving the traditional construction towards LC. Finally, the model can be applied easily in most countries to help decision makers in evaluating CWs and lean implementation in their construction projects.
