Final answer:
Poor communication, short-term planning, and risk management can result in low productivity and cost overruns in mega construction projects.
Step-by-step explanation:
Poor communication, short-term planning, and risk management can indeed lead to low productivity and cost overruns in mega construction projects. When there is poor communication among team members, it can result in misunderstandings, delays, and mistakes that can significantly impact the progress and success of a project. Short-term planning can lead to inadequate preparation and insufficient time allocation for critical tasks, which can lead to rushed work, rework, and cost overruns.
Additionally, inadequate risk management practices can result in unforeseen issues and delays, which can further contribute to low productivity and increased costs. For example, if potential risks are not identified and mitigated in advance, delays and disruptions caused by those risks can negatively affect the project's progress and financial outcome.
