Fast-track construction projects that begin with inadequate design information have become more common in response to rising construction industry demand. Fast-tracking shortens project duration while increasing rework. To achieve project deadlines while minimizing rework, specialists must select the best fast-tracking strategy. As a result, a questionnaire was developed to assess the success characteristics of fast-track construction and to provide constraints for these features and variables in national construction projects. National construction projects address specified government needs or investments in order to maximize the national return. The surveys limit these factors by specifying maximum and minimum percentages. These percentages were chosen in order to expedite project building. Period varies in national projects from the typical construction approach to the shortest time we can achieve with a plan. Cost and quality are within 20% and 10% of national project traditional construction methods, respectively. The best setting for various construction projects is determined by this proportion. It is preferable to use these percentages as a reference to complete construction projects in the shortest amount of time, with the highest quality, and at the lowest cost. This questionnaire was completed by sixteen building experts. Google Forms questionnaire was completed by 211 persons. This clarifies the results and construction variables time, cost, and quality.

Construction contributes to cities development. In Egypt, many projects had established using the accelerated method (ACM), others were traditional (TCM). Their life cycle cost (LCC) is analyzed to determine the benefit cost (BC) and decide the construction optimum way. In this paper, a Comparative study between LCC of ACM and TCM was held to improve the decision-making to form reasonable judgments on projects’ economics throughout their life cycle. The main question is what is the optimum way of construction to reach the highest benefit cost? Mustafa El-Nahass axis in Cairo studied, using LCC analysis to determine the development BC by analyzing the traffic impact before and after development. It was considered that operation cost (OC) of the axis were fuel and exhaust. Savings from OC by the ACM expressed by the case study BC. The main findings are that government entities should develop guidelines establishing the maximum time for construction. According to a prior study, extending construction time had no detrimental impact on public interest in these places. LCC study of the project was used to estimate this limit. This code specifies the regions to be classified based on traffic and population, and the maximum time for construction.
