A comparison of construction costs of concrete blocks, concrete caissons, steel sheet piles, steel deck and pile, concrete deck and pile docks, and selecting best of them.

Through carefully examining the types of berths in ports as well as the way they operate, and the time and costs involved in constructing them, mistakes can be avoided so that they can be constructed optimally, and consequently, higher efficiency in ports and docks will be achieved. Unnecessary maintenance costs will not be imposed in the future. Construction of durable and compatible docks with construction site as well as reducing the cost of finished berths and their execution time are the most important goals. In this research, five typical docks have been introduced, including steel deck and pile, concrete deck and pile, concrete blocks, concrete caisson and Sheet Piles, and the construction costs of them under real conditions have been investigated and compared. To do this, firstly, each dock is modeled in the Revit Structure program and the cost of making them are estimated by the Takeoff program. Real Construction price of steel deck and pile in the Khark island is 28.5 billion Tomans and the estimated price is 27.7 billion Tomans, which means that the estimated price for these docks is 5.04 % lower than the actual price, 5.04 % error is acceptable and the price estimate is correct by using Revit and Takeoff programs. By comparing the price of five docks, steel shields dock has the highest total cost of 49.95 billion Tomans, and the concrete deck and pile have the lowest total cost of 20.4 billion Tomans, which denotes that it is the most optimum wharf
