Sustainable development requires scheduling and implementing construction project tasks considering cost, time, quality, environment, and energy factors. For a decade, there have been infrastructural developments and a population boom in Khartoum state, Sudan, but it is adversely known for many uncompleted construction projects. The good news is that the structural Engineers and Developers have put tremendous effort into reducing structural failures closely to zero, thereby reducing cost. Despite these efforts, many issues hinder the timely completion of projects. The purpose of this study is to narrate the current management of cost and time in construction sites in Khartoum state. This study randomly collects as much data and experiences as possible from contractors, Engineers, and others involved in construction projects for a broader understanding and to suggest the best solutions. The questionnaire includes a total of 21 questions divided into four sections. Hard copies and an online questionnaire were sent to more than 90 professionals working on construction projects. A relatively high response of more than 80% was received from eligible identified professionals, and the data were analyzed using SPSS software. The results of this study concluded that natural, political, and economic factors are the most important factors affecting cost and time control. Furthermore, good coordination, monitoring, and appropriate fund management are the key factors that play an essential role in reducing construction project implementation duration and cost delays
