Sample interview questions: How do you conduct cost estimations for airport construction projects?
Sample answer:
When conducting cost estimations for airport construction projects, as an Airport Engineer, I follow a systematic approach that involves several key steps. Firstly, I gather all the necessary information related to the project, such as the airport design plans, project specifications, and any available cost data from similar projects. This helps me understand the scope and requirements of the project.
Next, I break down the project into various components, such as earthwork, pavement construction, terminal buildings, airfield lighting, utilities, and other infrastructure elements. I assess the quantities of materials, equipment, and labor required for each component by referring to engineering drawings, project specifications, and industry standards.
To determine the cost of materials, I obtain current market rates from reliable suppliers and factor in any potential price fluctuations during the project duration. It is crucial to consider the quality and suitability of materials to ensure compliance with safety and durability standards.
For labor costs, I analyze the required manpower for each phase of construction, considering the specific skill sets required for tasks like excavation, concrete pouring, steel reinforcement, electrical installations, and so on. This analysis helps in estimating the hours of labor required, including any overtime or shift differentials.
Equipment costs are estimated by considering the type and size of machinery needed, their rental or purchase rates, fuel consumption, and maintenance expenses. This estimation also includes any specialized equipment required for… Read full answer
