This construction video tutorial sheds light on definition of rough cost and detailed cost and variations among them.
Rough cost estimate plays an important role in construction. If there are huge variations among the rough estimate and the cost of construction that may impact the decision to begin a project. If the rough cost is too high, project may be left devoid of creating its detailed estimate.
Alternatively, if the rough cost is too low then project may begin but once the detailed estimate is made, design and drawings are cancelled because of shortage of fund.
Detailed cost estimates should be made cautiously. These briefly estimate the cost of different items work that set ups the entire project. Detailed estimates are accomplished once the detailed working drawings are made together with specifications. If any error occurs in rough cost estimate, then it will provide great influence in detailed cost estimates.
